CHAIRPERSON’s OvERvIEW

tHe eND oF tHe YeAR marked the beginning of Mintek’s 80th year in existence and South Africa’s 20th year of democracy. With such significant milestones upon us, it is important to consider the contribution and the impact the institution has made to both the South African mineral resources sector and to the lives of the ordinary people of South Africa. It is only by reflecting on what we have achieved so far that we can make an even better impact going forward.

Mintek also founded the Artisanal and small scale mining (ASSM) programme. the programme was established under the auspices of the Mining Qualifications Authority (MQA) and funded by the Department of labour as a National Skills Fund project. this programme ensured the upgrading of skills of small-scale miners, and enabled them to work more productively and to comply with legal, safety and environmental requirements. the Advanced Metals Initiative (AMI) at the Advanced Materials Division (AMD) was launched in 2006, the AMI of the DSt facilitates research, development and innovation across the whole value chain in the field of advanced metals. Mintek’s AMD focuses on value-addition to metals such as pGMs, gold and ferrous and base metals. Other significant achievement in 2006 was the commercialisation of the leachStar gold circuit controller. the year 2007 welcomed the introduction of two key research facilities, the HySA Catalysis Centre of Competence and the DSt/Mintek Nanotechnology Innovation Centre (NIC). the vision of the DSt/Mintek NIC is to be the leading provider of innovative nanotechnology based solutions for South Africa while the aim of the HySA Catalysis Centre is to produce pGM-based catalysts and to commercialise these in order to achieve 25% of the global fuel cell catalyst supply by 2020.

Mintek’s idea of developing a Ceramic Strategy for South Africa, contributed significantly towards job creation in the country. Since implementing the strategy in 2008, Mintek has set-up 19 pottery projects in 7 provinces across the country that have benefited 307 disadvantaged individuals, 23% of whom have some form of disability. Mintek has successfully demonstrated the transfer of ceramic / pottery technologies to rural and marginalised communities and by doing so have significantly contributed to poverty alleviation, skills development, job

over the last decade, key programmes at Mintek targeted products and processes, training and development and human capital development. Mintek’s Cynoprobe project is one such an example. In 2004, the Cynoprobe on-line cyanide-measurement system was installed on gold mines in peru, Mexico and Tasmania. The first commercial version of the flotation optimiser was commissioned at the world’s fourth-largest copper mine. In that year,

creation and business development. later that year, Mintek also celebrated the 100th installation of the Minstral furnace controller.

Regardless of the challenges experienced by the local mining houses it is quite reassuring that we have been able to build on our past performance and hard earned industry confidence to continue providing innovative products, services and technology. two examples of this in the platinum industry are the commissioning of the flotation pilot plant for Royal Bafokeng platinum and the continuation of the project demonstrating water atomisation of metal for Anglo platinum. the latter campaign has successfully demonstrated that difficult to process Platinum Group Metal feedstocks can be successfully transformed into metal powder that is amenable to further processing.

It is a positive development that Mintek continued to achieve a positive cash balance and the institution’s finances remained as solid as they have been for the past two years. However, going forward the effects of the ongoing strike in the platinum mining sector will impact negatively on our results for a long time to come as an operation such as ours experiences the effects long after incidents like these have passed. this is due to the fact that labour unrests often affect investor confidence and capital-raising ability. Consequently, this may result in some projects being postponed or cancelled. Regardless, we are hopeful that the expected stabilisation of the

global economic outlook will culminate in a positive demand for our products and services thus compensating for the negative effects of the strike.

During the year, several commercial projects were executed and several MTEF projects were finalised, the income of which contributed towards a positive balance. this we have achieved through collaboration with government, research institutions and the private sector. We are now anxiously awaiting the implementation of the Mineral and petroleum Resources Development Amendment Act, which include, among others, the enhancement of provisions relating to beneficiation of minerals. Now more than ever, with its implementation, South Africa has to demonstrate its innovation capacity with initiatives being championed at ministerial level. taking this into account, we expect our world class scientists and engineers to continue, at an accelerated pace due to more demand, to provide innovative solutions, including several instrument and technology prototypes, for the benefit of the industry in the medium term to long term.

Globally, energy and water efficiency remain determinants for viability of operations. It is our view that efficiencies relating to water and electricity costs will be achieved through technology advancements and improvements. looking back at the past eight decades of Mintek’s existence, one cannot help but notice the unintended consequences

of mining on the environment, or the potential thereof, particularly acid mining drainage and the scourge of abandoned mines. Acid mine drainage is a major threat to our water resources as polluted water from old mined out areas may contain toxic heavy metals and radioactive elements. these are not only dangerous to communities living in the mining areas but also to the flora and fauna. It is in this vein that Mintek is taking great strides to reverse this legacy of decades of mining in South Africa. the management of the campaign to rehabilitate derelict and ownerless mines, which is part of a contract with the Department of Mineral Resources, entered its second phase and already, one project has been completed as planned. the programme to process acid mine drainage is also at an advanced stage with the site preparation for the SAVMIN™ pilot plant in the West Rand being completed.

It is inevitable that the global mining industry is entering an interesting phase in Africa as the continent continues to become a growth opportunity for research and development. Governments are expending more energy to explore the possibilities of value-add beneficiation activities and this, coupled with an increase in exploration and development around the continent, creates an opportunity for Mintek’s research and development efforts.

largely unexplored territory, making the continent an attractive destination for exploration, platinum group metals, gold, chrome, diamonds, manganese and uranium, among other metals, and with this comes an opportunity for Mintek to play a role. As they mature and develop, African economies will need technology expertise in the mining sector. Several African mining authorities like the Geological Survey of tanzania (GSt) in tanzania as well as the ministry of mines in Malawi and Sudan are already showing interest in partnering with Mintek. this serves as an endorsement of our global position in terms of innovation, research, development and technology transfer. our products and services continue to be used in operations in various countries including Burkina Faso, Zimbabwe, Zambia, Ivory Coast,Ghana, DRC, Namibia and Mozambique.

However, as the developments around the protracted strike in the Western limb of the Bushveld Complex attest, communities are increasingly getting involved in terms of how the resources should benefit them. We therefore see community and social responsibility intertwining with labour relations and the regulatory space, especially in relation to the environment, and becoming an important aspect of the mineral resources value chain. Mintek is therefore proud to be setting up training programmes in some of the far flung but traditional mining towns for the benefit of the communities

living there. In the Northern Cape, for example, centres have been set up to train selected community members on the manufacturing of jewellery and cutting and polishing of gemstones while in other parts of the country, progress is being made to train communities on ceramic and pottery manufacturing. Mintek’s Small-Scale Mining and Beneficiation (SSMB) division continues to work with small scale miners, around South Africa, with the intention to incubate and educate miners with regards to legal and technical aspects of small scale mining. these solutions require building new relationships with labour, government and the industry and also take into consideration the needs of communities living in the mining areas.

let me conclude by expressing our gratitude as the Board to the president and Ceo, his management team and all members of staff at Mintek for making the first year of our tenure at Mintek as pleasant as it has been. We are encouraged and delighted that, regardless of the challenges; the institution has remained afloat and continued with its now sustained achievement of clean audits.

thank you to the outgoing Minister of Mineral Resources, Ms Susan Shabangu and her deputy Mr Godfrey oliphant, for having entrusted us with this responsibility and for their political guidance whenever we needed it. on behalf of the Board, I extend a warm welcome to Adv Ngoako Ramatlhodi, the


incoming Minister of Mineral Resources and congratulate Mr Godfrey oliphant on his reappointment. the Board pledges its cooperation with them and hope to work diligently at Mintek in order to contribute building a better South Africa.

CEO’s STATEMENT

NotWItHStANDING tHe MANY CHAlleNGeS faced by the South African minerals industry, Mintek continued unabatedly with its mineral processing and beneficiation drive mainly on Research and Development that is supported by the parliamentary grant. Due to these industry challenges, Mintek revenue was R74 million shy of the budgeted total revenue. However, the continuous culture of saving that has been entrenched in the group, posted a surplus that is 11% more than in the previous year.

looking ahead, there is little doubt that the global mining industry is poised to enter a period of distinct structural change as the rest of the continent is becoming the new exploration destination due to its untapped and largely unexplored resources. Mintek followed the trend during the year by increasing its role in the continent. Mintek successfully sold a 75kg/h Minfurn Carbon Regeneration Furnace to a company in Ivory Coast. the Minfurn offers an alternative to the traditional rotary kiln used in industry for regeneration of activated carbon. Mintek also successfully collaborated with the Geological Survey of tanzania (GSt) through a visit to their laboratories. the visit was part of a complex multi-disciplinary project known as SMMRp (sustainable management of mineral resources project) in tanzania. the purpose of the visit was to carry out a needs requirement analysis in order to be able to assist GSt with their laboratory upgrade through acquisition of essential equipment and setting up of operational procedures with a view to achieving international accreditation. the visit was very successful and culminated in a full report of recommendations to the GSt. Mintek also hosted an engineer from the Malawi Ministry of Mines for one month. the purpose of the visit was to get exposure to Mineral processing activities at Mintek. Mintek was chosen due to its reputation in the metallurgy and mining industry, and due to South Africa being a member of Southern African Development Community (SADC). During his stay, the engineer was exposed to various theories in Mineral processing followed by practical observation of test work and pilot plant execution and his visit coincided with the commissioning of the Royal Bafokeng pilot plant.

on the process monitoring and control front, large installations of Mintek’s world leading FloatStar level Stabiliser (FSlS) and MillStar technologies were also completed at a number of Southern African concentrators, including a FSlS at Mimosa in Zimbabwe and a full MillStar and FSlS for Mopani Copper Mines in Zambia. Furthermore, strong sales of Mintek’s Cynoprobe online cyanide concentration measurement instrument were experienced, with 15 Instruments being sold during the year, including four to Burkina Faso, one in Ivory Coast and one in Ghana.

In the area of nanotechnology, the MinpeptidestM facility (under the Biolabels unit) has been refurbished and is completely operational. the facility produces peptides

for R&D and commercial purposes. MinDiagnosticstM (also under the Biolabels unit) has sent the Malaria Diagnostic kit for field trials in Kenya while the HIV diagnostic tests have been validated on clinical samples and are now ready to be audited by the DSt. the Cholera diagnostic prototype has entered into an advanced stage and is being tested in the presence of interfering species.

Finally, as exploration and development spend no longer comes to South Africa as before, owing to limited “downstream” beneficiation, we are concerned but as a recognised leader in the minerals technology field, we will continue to call upon our scientists and engineers to provide innovative solutions for the future that will benefit the industry as a whole.

Financial Summary

After the effects of the financial crisis, Mintek was able to continue to make a sustainable surplus for the past three years

with varying degrees of success. With concerted efforts to contain cost, we continued to bear fruits but due to problems experienced mainly with our water atomisation project, our surplus ended up shy of the anticipated amount. However, the principles of atomising metal to produce powder have been successfully demonstrated on material that is difficult to treat.

this year Mintek achieved a surplus of R17.4-million, which is an improvement of 71% on the targeted amount of R10.4-million. This year’s financial achievement was made possible due to the execution of several pilot plants, finalisation of several MTEF projects and the generation of higher than expected income through rentals and investments. However, despite the surplus, our total income of R462-million was lower than anticipated due to the Bay 2 downtime and a decrease in commercial work towards the third quarter of the year. However, we are hopeful that the global financial outlook will be reaching some stability going forward and

accompanied by a positive demand for our products and services leading to more commercial activities and stronger income streams.

Technical Highlights

Mintek’s started the construction of a pilot facility for the demonstration of processing technology for rare earth elements (Ree) last year. the aim of the facility was to aid the development of a number of Ree mines in Southern Africa as well as downstream high-technology Ree manufacturing enterprises. the installation of this rare earth pilot plant has now been completed. the water commissioning as well as the configuration and calibration of the pH control system have also been completed. the main focus now remains on the generation of the process design criteria from laboratory scale test work and this will commence in the new financial year.

Acid mine drainage (AMD) is a threat to our country as the flow, or seepage, of polluted water from old mined out

areas may contain toxic heavy metals and radioactive elements which are dangerous to people’s health, as well as plants and animals. Mintek’s response to this was the development of the SAVMINtM process which is a novel technology for treating polluted mine water. the SAVMINtM process has several major advantages compared to similar technology applications. Amongst others, it can treat a wide spectrum of polluted mine water (i.e. from gold, platinum, coal and base metal mines) and waste products from the process can be disposed of either as a stable waste, or, in certain instances, constitute a usable by-product. A suitable test site for demonstrating the SAVMIN™ technology had been secured on the West Rand and an agreement with the site owners has been finalised.

Construction of the slab and the site preparation for the SAVMIN™ pilot plant are complete. procurement of mechanical equipment is complete while the assembly of equipment at Veolia workshops is 75% complete. A plan to mitigate expected delays in the installation due to the design of the cyclone circuit and site interface circuits has been formulated. Significant time savings from on-site fitting is expected. In order to compensate for potential delays in the test work start date, an extension to the original Gold one site use agreement has been negotiated to be until May 2015.

Due to new operating conditions required for test work on the automated continuous autoclave plant, certain aspects of the installation had to be assessed, not only from a legal and design perspective, but also from training and operational perspective to make sure it is completely safe for use. An international expert in the operation of autoclaves was approached to evaluate all aspects of design, installation and operation of the pilot plant to specify all modifications and checks required to ensure safe operation. the automated continuous autoclave plant is scheduled to be commissioned in the second quarter of 2014. there is continuous interest in the facility and it is envisaged that a successful pilot campaign can convert interest into

commercial revenue for Mintek.

We continued to increase our market penetration of products in the area of advanced process control for flotation, milling, furnace control and cyanide measurement and control throughout the world. the Cylas device, an online laser-based distance meter that can be used for measuring the hydroclone underflow flare angle, was sold to local and international clients. Mintek also investigated the feasibility of utilising solid state thermoelectric generators to recover thermal energy from hot tapped ferroalloy metals, where significant amounts of latent heat are presently being lost to the environment. A laboratory-scale setup was constructed to test readily available thermoelectric devices to determine the practical viability of the technology. Results indicated that although there are reports of highly efficient thermoelectric devices in circulation, these are highly specialised proprietary devices, and generally, available units still suffer from very low efficiencies. As the technology further evolves, it may become a more attractive prospect in future.

our Nicksyn™ synergistic nickel extraction reagent was piloted successfully for an international nickel producer. Sales of the reagent are likely to provide significant income to Mintek as well as potential new implementation and test work due to commercial exposure of the reagent. the nickel extraction reagent has attracted further interest from other large international process engineering companies. this is expected to accelerate the introduction of this technology into the market.

Mintek continued to manage the DMR’s derelict and ownerless mines project during the year. However, due to the timing of the conclusion of the contract to further manage the rehabilitation of derelict and ownerless mines for a further 3-year period, we were able to finish only one of the four targeted projects, the Strelley Mine revegetation project. the majority of the programme spending has been directed towards planning and procurement, while spending on rehabilitation project implementation

is envisaged to increase rapidly when construction work commences next year. Going forward, the Mintek team will ensure that the rehabilitation designs are much more robust than the previous practice and thus realise more sustainable, long-term solutions.

During the second year of the MteF project in the Northern Cape, buildings were selected that would serve for the set-up of gemstone training and beneficiation centres. Gemstone cutting and polishing equipment were moved to a building in prieska and the training of twelve learners in jewellery manufacturing and another two learners in gemstone cutting and polishing continues. “Die ou Mill Huis” which is known as a tourist attraction will be utilised in upington for training, manufacturing and as a point of sale. the project has the full support of both local and District Municipality and also the Rotary Club. the Kimberley Diamond and Jewellery Centre will be utilised as the third centre. this building currently houses the Kimberley International Diamond and Jewellery Academy (KIDJA). the introduction of the cutting and polishing of semi-precious gemstones will complement the training already conducted by the academy which is diamond polishing training. the project is supported by the Northern Cape economic Development and tourism Department.

through the training of ceramic and pottery manufacturers (CpM), Mintek developed the idea of drying the clay products produced by their project beneficiaries by using solar energy as opposed to electricity. A low cost solar oven was successfully designed and manufactured and the technology was transferred to a group of potters in Giyani.

this year, I am proud to again announce that Mintek was named a winner in the Sunday times technology top 100 Awards for excellence in the Management of Research. In addition, we were announced as a finalist in the category of Management of technology, Innovation people and Systems. Similar accolades were bestowed upon us last year.


Safety, Health, Environment and Quality (SHEQ)

this year, Mintek again passed a surveillance audit against ISo 9001:2008 (Quality), ISo 14001:2004 (environmental Management) and oHSAS 18001:2007 (Safety and Health) standards.

the lost time Injury Frequency Rate (ltIFR) at the end of the year was 0.5, well below the target of 1. this is the lowest that the ltIFR has been in over 2 years. We will continue to emphasise Health and Safety with a view to lowering the ltIFR even further. unfortunately, Mintek suffered five lost time injuries during the year. All injuries were either hands or legs, four of which resulted in lacerations. Since four of the injuries occurred at engineering and Maintenance Services (eMS), clear plans were put in place by this division to diligently conduct work place inspections, with the emphases on training and job observations in an effort to reduce the number of injuries.

Focus on making our clients happy has continued to pay off as can be seen from our Client Dissatisfaction Frequency Rate (CDFR) which has decrease further and was 5 at the end of the year, well below the target of 10. this means that only 5% of clients that were surveyed were unhappy with any aspect of Mintek’s services.

the public Dissatisfaction Frequency Rate (pDFR), which amongst others, measures public complaints about noise levels resulted in a pDFR of 4, indicating 4 complaints in the past year against a target of 1. All complaints were investigated and found to be genuine and were related to maintenance failures that were immediately corrected. this is the only statistic that is of concern relative to our targets. A noise monitoring programme has been introduced to enable Mintek to detect noise levels, which are above an acceptable decibel level, before they escalate into complaints by our neighbours.

there were no major environmental incidents which occurred over the preceding 12-month period resulting in

an environmental Incident Frequency Rate (eIFR) of 0. the Health Incident Frequency Rate (HIFR) changed from 0 to 0,13.

People

In growing the talent pipeline for Mintek in the medium to long term, we implement a number of development programmes. the Graduate Development programme (GDp) and an Internship programme are examples of such programmes. through the GDp we recruit young scientists and engineers into Mintek and take them through a structured development programme which produces graduates that have a comprehensive understanding of the business of Mintek. Due to a diminishing staff turnover rate, we reduced the number of full time bursaries for students and instead, awarded more bursaries for part time studies to our staff. During the year we awarded a total of 129 bursaries to employees for both undergraduate and postgraduate studies. the undergraduate programme is strongly allocated to Africans and female employees.

Mintek also has a Work-Integrated learning (WIl) programme for Diploma students and an Artisan learnership programme implemented in partnership with the Mining Qualifications Authority (MQA). This year, the physical Metallurgy Group has managed to facilitate industry placements for 37 interns under the DSt-WIl programme.

At school level, Mintek promotes Science, technology, engineering and Mathematics through a special programme known as Minquiz. this is a National Science competition for grade 12 learners.

Mintek continues to focus its training interventions for its employees on technical and soft skills. At the end of this year, we managed to spend over R5.3-million on training which was in line with the target of 2% of payroll.

The Future

As South Africa continues to build a future for our youth, we will continue

with our efforts to ensure that the many challenging but yet achievable milestones set out by the National Development plan in 2013 come to fruition. We therefore look forward to expanding our various learnership programmes, enriching our graduate development interventions and intensifying the training of our artisans and technical professionals.

Whilst we thank the Honourable Susan Shabangu and her team for her guidance during the course of the year, we welcome and call upon the insightful leadership of the Honourable Minister Ngoako Ramatlhodi supported by Deputy Minister Godfrey oliphant and their entire team at the Department of Mineral Resources as we continue on our journey to help make this country an excellent place to live in.

In conclusion, I would like to express my gratitude to our Board of Directors, led so astutely by Advocate linda Makatini. In particular, I wish to thank the Board for their commitment, integrity and hard work in ensuring that Mintek lives by its vision and fulfils its mandate and responsibility towards the minerals industry. My appreciation also goes to the executive team for their commitment and unwavering dedication to ensure that Mintek continues to innovate and produce, often under difficult circumstances. lastly, thank you to all our employees. I believe that with all our continued hard work, next year will be an even better year for our organisation.

And so, as we salute Mintek on its 80th birthday this year, I wish to recognise all the individuals, past and present, and the many stakeholders that in a variety of ways contributed so generously of their time and effort to support the work of Mintek throughout this financial year and indeed over the last eight decades.

the ARC comprises of three non-executive directors of the Board, two independent members appointed by the Board, the Ceo in his capacity as an ex-officio member and three executive members representing the company portfolios of finance, corporate services and risk. the executive members previously attended the ARC as invitees and were formally appointed by the Board on 31 January 2014. the Auditor-General South Africa and the Internal Auditor attend as invitees. Both internal and external auditors have unrestricted access to the ARC.

During the past year, the ARC considered various reports from the internal auditor, while the audit report on the financial statements from the external auditor was considered first by the ARC and then by the Board. the Auditor-General expressed (pages 52 and 53) audit opinion on Mintek’s annual financial statements for the year ended 31 March 2014.

Internal Control

Mintek maintains internal controls and systems, designed to provide reasonable assurance regarding the integrity and reliability of its financial statements, to safeguard, verify and maintain the accountability of assets, and to comply with applicable laws and regulations. the effectiveness of these controls is monitored by the internal auditors, who report to the Audit and Risk Committee. the Audit and Risk Committee requested management to review and evaluate Mintek’s existing internal controls to further identify areas that can continually be improved upon.

Internal Audit

Internal Audit is established in terms of section 51(a)(ii) of the public Finance Management Act No. 1 of 1999 as amended. Mintek’s Internal Audit (IA) is governed in terms of the Standards for the professional practice of Internal Auditing (SppIA) as prescribed by the Institute of Internal Auditors.

Mintek’s IA function is an independent, objective assurance and consulting


activity designed to add value and improve Mintek’s operations.

Human Resources Committee

the Human Resources Committee (HRC) consists of three Board members and the CEO as ex-officio member. the GM: Corporate Services and the Manager: Human Resources attended as invitees. the HRC reviews and determines the remuneration and terms of employment for Mintek, and as part of this process, the HRC gives consideration to the annual review of remuneration packages based on independent surveys. the HRC also looks into HR policies, internal controls, circumstances, conditions and activities that affect material changes to policies and procedures and conditions of service for all employees.

Technical Committee

the technical Committee (tC) is established as a Committee of the Board to assist the Board in discharging its duties relating to Mintek’s core business. It provides a forum for discussing technical issues for developing relevant recommendations for consideration by the Board in informing strategy development and implementation in Mintek. Furthermore,

Attendance at Human Resources Committee MeetingsName Category Possible Attended

D Block (Chairperson) Non-executive 3 3

V toni penxa Non-executive 3 2




the tC is set up to advise on utilisation of expertise, project proposals and financing thereof, looking into various strategies and the possible expansion of Mintek business within the said mandate. In addition to the above, the tC must ensure that there is compliance with any other function or responsibility as may be prescribed by relevant legislation and in line with national priorities.

the tC consists of three non-executive directors of the Board, the Ceo as ex-officio and three executive members of Mintek who are responsible for Business Development, technology, and Research & Development. the executive members who previously attended the tC as invitees, were formally appointed by the Board on 31 January 2014.

Fraud Prevention Committee

Mintek has adopted a fraud prevention plan that incorporates principles contained in the public Sector Anti-Corruption Strategy, and which focuses particularly on creating awareness and promoting ethical business conduct. the Fraud prevention Committee, which consists of standing members with roles in Finance, Security and the Human Resources Division (HRD) as well as a neutral Chairperson, is tasked with an ongoing review of the effectiveness of internal controls.

Management

Mintek is managed by a Chief Executive Officer assisted by five General Managers. this team makes up Mintek’s executive Management Committee and meets on a weekly basis to review strategic and operational issues.

executive Management is supported by fourteen formally appointed Divisional Managers who are in charge of Mintek’s operating divisions and centralised support functions.

Operational Performance

Mintek reports to the Department of Mineral Resources (DMR) and is also accountable to the Department of Science and technology (DSt) for its technology-related Research and Development (R&D) activities. Various Key performance Indicators (KPIs), encompassing financial, organisational, innovation and learning, human resources and transformation perspectives, provide Mintek with a basis for evaluating its activities in the identified key performance areas.

each KpI is supported by a set of identified measures, that provide a more specific and consistent base from which to assess progress. there is also a framework for peer review should the need arise.

While Mintek’s executive Committee meets on a weekly basis, the Management Committee convenes on a monthly basis where business plans, financial results and policy updates are presented. the budget for the current year is reviewed in September by executive management in order to keep track of and ensure overall sound financial management.

Going Concern

the Mintek Board reviewed the entity’s financial budgets for the period from 01 April 2014 to 31 March 2015 and is satisfied that adequate resources exist to continue business for the foreseeable future.

Safety, Health, Environment and Quality (SHEQ)

During July 2013, Mintek’s SHeQ management systems underwent a combined surveillance against the requirements of oHSAS 18001:2007 (Safety and Health), ISo 14001:2004 (environmental Management), and ISo 9001:2008 (Quality). Mintek has been certified by accredited independent external auditors to

meet the requirements of safety and health (oHSAS 18001), environmental management (ISo 14001), and quality (ISo 9001).

the lost time Injury Frequency Rate (ltIFR) remained above target for the first six months of the year. However, by the end of the year it had decreased to 0,5 which is well below the target of 1.

the environmental Incident Frequency Rate (eIFR), Health Incident Frequency Rate (HIFR) and the public Dissatisfaction Frequency Rate (pDFR) was zero throughout the year; HIFR has increased to 0,13. However the public Dissatisfaction Frequency Rate (pDFR) increased to 4 due to 4 noise complaints.

the external Client Dissatisfaction Frequency Rate (CDFR) decreased continuously during the year from 9 at the beginning of the year to 5 at the end of the year, which is below the target of 10. The drop is a result of significant effort being expended in improving our service to clients and more intense oversight of remedial activities. every client survey that indicated a measure of client dissatisfaction was analysed by the Business unit involved and the necessary corrective action taken.

A groundwater quality assessment indicated that the overall groundwater quality underlying the site is good with no significant impact from any potential contamination sources.

Radiation Protection Programme

Mintek is registered as a uranium and thorium test work facility with the National Nuclear Regulator (NNR) and the Department of energy (Doe). Mintek has been issued with the following authorisations from the Department of energy:

• Exportation of Uranium and Thorium.

• Importation of Uranium and Thorium.

• Possession of Uranium and Thorium.

• Acquisition, processing, use and transportation of uranium and thorium.

the Radiation protection programme (Rpp) has been incorporated as part of the overall Safety, Health, and environment programme, and an internal audit schedule has been implemented to ensure that the Rpp remains relevant and is updated as approved by the NNR.

MINteK, one of the world’s largest and longest running minerals technology facilities is known for providing comprehensive, accredited metallurgical, analytical and mineralogical services across all metallurgical disciplines. Mintek has been in existence since 1934 and strives to continually develop unique technologies and products. Also, Mintek has more than 700 employees, including engineers and scientists that contribute to the overall understanding of Southern African and worldwide mineral resources.

During the year the following activities were undertaken by Mintek:

GOLDthe current gold price and the general depletion of free milling gold deposits have stimulated an increase in gold projects world-wide. Many of these projects are under time and budget constraints, which necessitate the execution of focussed development and test work programmes to provide relevant information for the comparison of available processing options and economic trade-offs.

there has been an increase in requests for XRF sorting of gold ore with current work being conducted for Village Main Reef and testwork for Anglo Gold Ashanti being in the pipeline. these have the potential to develop into full scale pilot projects and are expected in the third quarter of next year. the technology is now able to track gold proxies that were previously difficult and now can increase the amount of gold recovered. XRF sorting on gold ores from Barberton Mines showed that waste reduction can lead to enhanced gold recovery.

the Hydrometallurgy Division (HMD) organised a highly successful Gold Day on 30th July 2013 to re-establish strong links between Mintek and the gold industry. this event allowed Mintek to showcase its gold expertise and attracted over a hundred participants from the gold industry in South Africa. the response to this day was very good and a number of enquiries to several Mintek divisions could be linked directly to the Gold Day. the Cyanide Centre has maintained its Sanas 17025 accreditation.

Advanced Leach Facility

the Advanced leach Facility (AlF) in the Gold Group is complete. this has allowed parallel operating and data capturing which allowed HMD to reduce the cost per leach test from R19 000 to R8000. Subsequently, this allows HMD to offer this service at a reduced cost to their clients. the increased affordability is expected to stimulate an increase in demand for work at the AlF thus increasing revenue.

Gold Catalysis

the Catalysis group received a new order to deliver 75 kg of gold catalyst to SIMSA in Chile. A large percentage of this order has already been delivered. Gold catalyst has also been supplied to a gas mask manufacturer in the uSA for testing. thus far, the manufacturer has reported excellent results. Additional tests are under way and the company has shown interest in purchasing a further 300 kg of gold catalyst. Beth el Industries from Israel, with whom Mintek had a strong relationship since 2007, has requested a quote for 336 kg of gold catalyst.

the group has also developed a new

gold catalyst that shows excellent conversion and selectivity efficiency in the oxidation of ethanol to acetic acid. Gold catalyst development has progressed to a stage where a series of Au/tio2 core-shell catalysts, Au/nano-structured-tio2 and surface acidity modified Au/TiO2 catalysts can now be synthesised. tests are ongoing to determine if these catalysts are more durable than the group’s Au/tio2 catalyst.

Advanced Materials Division (AMD) ensured that a successful precious Metals 2013 conference was hosted by Mintek under the precious Metals Development Network (pMDN) of the Department of Science and technology’s (DSt) Advanced Metals Initiative (AMI). the DSt has expressed its satisfaction to Mintek with regard to the success of the conference. the catalysis group presented 2 oral papers at the conference which were well received.

Nanoscience and Nanotechnology

the Nanotechnology Innovation Centre (NIC) at AMD has made significant contributions during the year. the four contributing units at the NIC include Biolabels, Water, Sensors and Nanominerals. At the start of the year, NIC implemented VISIoN 2015 which brought about realignment of projects to focus NIC activities towards developing products and services in line with the management and operational plans of the NIC Cleanroom facilities (ISo 3 and ISo 5). NIC researchers received training locally and abroad, in line with envisaged ISo 3 and ISo 5 projects. Further to this, the business plan for projects relating to malaria, membranes and screen printed electrode (Spe) were outlined in order to address the commercial aspect of these R&D projects.

the Sensors unit successfully demonstrated the capability to produce and validate large scale Spes. In addition, an electrochemical elISA Malaria biosensor as well as a Cholera biosensor have been internally validated. NIC Sensors Group is currently collaborating with Mintek’s Measurement and Control Division (MaC) to develop a sensing unit for this technology.

towards the later part of 2013, the

An electrochemical ELISA Malaria biosensor as well as a Cholera biosensor have been internally validated by AMD.

NIC Water unit received a scale-up reactor to perform the grafting reaction of membranes at a significantly larger scale (up to 20 l). Researchers from NIC Water fabricated and tested peS-g-PSS capillary ultra-filtration membranes at Ikusasa Water in Cape town. these were tested using normal membrane tests and were also used to treat river water. It was demonstrated that the new membranes had higher flux than the baseline membranes, a great achievement for the unit. NIC Biolabels and Nanominerals have developed several nanostructured materials as products and for in-house applications including new monolayer protected clusters, bioconjugates and peptides.

the MinpeptidestM facility (under the Biolabels unit) has been refurbished and is completely operational. the facility produces peptides for R&D and commercial purposes and currently services Wits university, university of pretoria and the Biomed Group within AMD. MinDiagnosticstM (under the Biolabels unit) has sent the Malaria Diagnostic kit for field trials in Kenya. the HIV diagnostic tests have been validated on clinical samples and are now ready to be audited by the DSt. the Cholera diagnostic prototype has entered into an advanced stage and is being tested in the presence of interfering species.

the NIC have strived towards producing high-quality publications in international peer-reviewed journals and presentations at both international and national conferences.

Continuous Autoclave Plant

Due to new operating conditions required for test work on the automated continuous autoclave plant, certain aspects of the installation had to be assessed, not only from a legal and design perspective but also from a training and operational perspective to make sure it is completely safe for use. As part of a dual approach to get the plant ready for operation, all the individual components were certified by an authorised certification engineer. This certification was based on actual measurements and confirmation of the design calculations. A design data book was compiled from the measurements. An international expert in the operation of autoclaves was approached to evaluate all aspects of design, installation and operation of the pilot plant to specify

all modifications and checks required to ensure safe operation. Although this resulted in extra commissioning costs, it significantly reduces the risks associated with the operation of the plant. orders for long lead items as well as layout drawings and piping schedules have been completed. In addition, physical inspection of the individual components is complete and all the welds have been X-rayed and certified for use at the intended process conditions. Furthermore, all the pressure vessels have been tested and nameplates issued to certify compliance with legal requirements for the intended use. the automated continuous autoclave plant is scheduled to be commissioned by July 2014. there is continuous interest in the facility and it is envisaged that a successful pilot campaign can convert interest into commercial revenue for Mintek.

Mintek AuSimPro: Gold Process Advisor

Mintek has developed the AuSimpro Gold processor Advisor. the AuSimpro is a growing database in which Mintek’s knowledge on historical as well as current projects is captured. Such information includes among others, gold grades, mineralogical information on the ore, site location and gold recovery. AuSimpro uses a proprietary algorithm to provide suitable baseline options for any new gold project by comparing the input pertaining to mineralogy, ore type and metallurgical information from sourcing tests against the database. the knowledge contained in AuSimpro results in better decision-making and cost and time saving by increasing the efficiency and focus of the development work.

Minfurn Carbon Regeneration Furnace

Minfurn offers an alternative to the traditional rotary kiln used in industry for regeneration of activated carbon. In the year, the responsibility for the Minfurn product was allocated to the pyrometallurgy Division and the Division embarked upon an active marketing campaign to facilitate the re-branding of the product internationally. The Division’s first order for a 75 kg/h of Minfurn was successfully handed over to a satisfied client at the end of November 2013 and commissioning was successfully concluded at their gold mine in Ivory Coast during January 2014. Installations of Minfurn units


across the world continue in operation and positive feedback is received continuously from existing clients. Mintek is actively involved in developing the Minfurn for application in the water and food industries and aims to expand the current client base significantly.

PLATINUM GROUP METALS the platinum group metals (pGMs) refer to six transitional metal elements viz. Iridium (Ir), osmium (os), palladium (pd), platinum (pt), Rhodium (Rh) and Ruthenium (Ru). they are chemically, physically and anatomically similar, and uniquely durable. In addition, their ability to be recycled ensures a uniquely long lifecycle as well as protection of the environment by reducing metal waste disposal. they are the densest known metal elements and are most often used as catalysts because of their chemical stability. However, prior to application, the mined, raw material is first treated to improve the PGM concentration. Mintek’s MpD treats the raw material through a process involving comminution and flotation.

Flotation Test Work

there has been renewed interest in platinum Group Metals (pGM) testwork from Zimbabwe focussing on talc

depression. two projects are currently at proposal stage for pilot plant testwork where a client is looking at increasing tonnage through the existing plant and the other client is looking at a greenfields Pt project. Locally, flotation pilot plant campaigns were undertaken for Royal Bafokeng platinum, the results of which indicated that Royal Bafokeng platinum could increase tonnages through their existing plant without the need for building a new concentrator at Styldrift.

A lot of testwork is currently being done for Ivanhoe platreef on their platreef deposit in the North West. this is a green fields operation with future pilot plant testwork being required to confirm design data.

Sensor-Based Sorting

Rados X-ray fluorescence surface assay remains an effective method for discriminating between barren

and mineralised waste in these ores. over 10 bulk samples (20 tons) from various mines have been evaluated. Downstream milling and flotation benefits have been evaluated showing good potential for reduced operating costs at identical pGM recovery. ore variability tests have shown that the X-Ray sorter techniques can produce consistent discard grades with varying head grades of sample. Although there was a decrease in new requests for pGM sensor-sorting projects, the Minerals processing Division has focused mainly on packaging testwork results so that the technology can be implemented at the respective mines. projects for Anglo platinum have contributed to the approval of a proof-of-concept plant which is scheduled to be commissioned next year.

Fuel Cell Catalysts

the HySA Catalysis group at the AMD have seen the first low temperature peM (proton exchange Membrane) MeAs (Membrane electrode Assembly) fabricated at 50 cm2 active areas with performance matched at industrial benchmark MEAs. This significant increase in area, when compared to earlier fabricated MeAs, is a milestone in the group’s path to assemble the first short fuel cell stacks. Production of an advanced 20 wt% ptCo/C fuel cell catalyst has reached the 40g per batch scale while maintaining the enhanced activity compared to pt-only catalysts. progress towards achieving the same performance on higher loadings of 40wt% ptCo is at an advanced stage. Development of the 40wt% ptCo/C fuel cell catalyst has advanced considerably and its enhanced activity is retained at the 2g batch size. Work towards scaling this activity to 50g batch size is underway. the 20 wt% ptCo/C catalyst was previously scaled to 50g batches and has now been benchmarked against and shown to be equivalent to commercial material from premetek, uSA.

Commercialisation of the HySA developed fuel cell catalysts looks promising. A German university that runs a large fuel cell programme has requested a quotation for 200g of pt/C catalyst. Discussions with other potential customers are ongoing through HySA partners at the university of Cape town (uCt).

2 independent reviews were conducted

on Mintek-hosted DSt programmes, 2 under the Advanced Metals Initiative (AMI), the precious Metal Development Network (pMDN), the Ferrous Metals Development Network (FMDN) and the HySA/Catalysis Centre of Competence (hosted by uCt and Mintek). the review feedback indicated that the programmes have achieved their mandate and should, from here on, concentrate on the commercialisation aspect with industrial partners.

Water Atomisation

21 months of the two year contract for the operation of the demonstration plant for the water atomization of alloys have been completed. overall 1756 tons of metal has been produced from nearly 12 500 tons of feed. About 670 tons of metal was successfully converted to metal powder. During the second year of operation, the furnace lining required replacement and a shutdown was planned for July 2013. During the plant shutdown, the pyrometallurgy Division embarked on a titaniferous magnetite pilot plant vanadium smelting campaign for a South African junior company. this deposit located north of Mokopane was successfully completed in the Bay 1 DC-arc furnace. the atomising plant was re-commissioned during September 2013, but an unfortunate hot metal leak occurred during an atomisation run. the hot metal spillage was contained, but resulted in significant equipment damages, delaying the re-start of the project. the duration of the outage was extensive due to a breakdown on the main power supply for the facility. the atomizer facility was restarted after repairs to the power supply were concluded in January 2014, but ramp-up was limited due to unseasonal rains during the months of February and March, which hampered the drying rate. the main focus remaining for the project is to treat the existing stockpile of metal and convert the valuable metal product to powder. to this end a new roof panel for the DC furnace was designed to allow for loading of ingots directly into the DC furnace. the new roof design adds additional flexibility to the plant. Nickel recovery from the waste material consistently exceeds 95% thus successfully demonstrating the recovery of nickel from difficult to treat materials.

URANIUM AND BASE METALS uranium is a clean energy source that will be used well into the future to help meet the world’s growing energy requirements. As more nuclear reactors come online, the demand for uranium will increase, resulting in higher uranium prices. Nuclear power accounts for nearly 6% of the world’s energy and 13% of the world’s electricity. uranium, used in nuclear power, is a relatively clean source of energy that does not produce greenhouse emissions.

Base metals are the major industrial non-ferrous metals other than precious metals. the base metals’ major applications are found in industries such as automotive and transport, building and construction, infrastructure, electrical and electronics, packaging, consumer goods and batteries. over the last 10 years China has overtaken the traditional markets in europe, the uSA and Japan. China now accounts for around 40% of global production and consumption of each base metal, i.e. aluminium, copper, lead, nickel, tin and zinc.

Mintek, SRK Consulting and Goviex are currently discussing the prospect of a pilot scale uranium sorting, ablation and hydrometallurgical project. Approval of this project will lead to a proof-of-concept plant being assembled at Mintek. this is expected in the third quarter of next year.

Cu/Co test work from DRC and Zambia has maintained its high pace with test work ranging from scouting level (feed characterisation and basic amenability testing) through to assessing modification/alterations to existing plants.

Recently the Kamoa project test work has been acquired, which was initially conducted at a competitor in Canada. Mintek showed that it was able to reproduce results obtained in Canada. the test work is now focussing on improving the flowsheet as the number of milling and regrinding stages make the project uneconomical. other base metal projects are focussing on variability studies and treating of lower grade material.

There has been a steady flow in tantalite projects with a feasibility study on the Noventa Highlands African

Mining Company (HAMC) Marrua tantalite ore body that focused on spiral test work being undertaken.

Gravity separation work was done on a Cassiterite (Sno2) dump sample for the Pacific Strategic Minerals Group in Spain. The flowsheet consisted of 4 stages (Rougher, Cleaner, Scavenger, Re-Cleaner) of spiral work, followed by two stages of Shaking table. the ore responded favourable to gravity separation and the final gravity product showed 12% Sn content in 0.4% of the overall mass and was able to recover 86% of the Sn by Wet High Intensity Magnetic Separation.

As part of the on-going research programme assessing sensor-based sorting applications in the minerals industry, the new sorting initiatives with tomra (formally Commodas-ultrasort) have shown that previous difficult ores like Kimberlite and Manganese can now more easily be sorted via Near-Infrared Spectroscopy. this new technique can also be used for effective removal of non-mineralised waste from pGM ores to particle sizes as low as 10mm (compared to the Rados XRF sorting equipment where the lower limit of particle size is 30mm). Notwithstanding this, testwork using the Rados XRF sorter has been on-going on uG2, Merensky and platreef ores from Anglo-platinum with very encouraging results.

preliminary work using laser sorting has shown good promise in recovering Witwatersrand reef from waste. Sorting of base metals has been slow initially but there has been an increase in requests with 400 tons of copper ore expected later this year. Bathlako Chrome is assessing the potential for the use of sensor based sorters instead of conventional Dense Media Separation (DMS) plants in pre-concentration of lumpy ore.

the Nicksyn™ synergistic nickel extraction reagent developed at Mintek was piloted successfully for a large international nickel producer and has been included in the feasibility study for a new project. Sales of the reagent are likely to provide significant income to Mintek as well as potential new implementation and test work due to commercial exposure of the reagent. the nickel extraction reagent has attracted further interest from other large international process engineering companies. this is expected to further

accelerate the introduction of this technology into the market.

Very encouraging flotation test results have been obtained on a copper ore from Zambia (Konkola) and a pilot plant campaign processing 100 tons of sample is now planned.

INDUSTRIAL MINERALSIndustrial minerals may be defined as minerals mined and processed (either from natural sources or synthetically processed) for the value of their non-metallurgical properties, which provides for their use in an extremely wide range of industrial and domestic applications. As a general rule, they can also be defined as being non-metallic, non-fuel minerals

the Fluorspar work has maintained a high pace. pre-concentration of Fluorspar through Dense Media Separation, followed by downstream flotation is on-going. Several Fluorspar projects have been undertaken mainly for clients such as Sephaku, Witkop, Doornhoek and Mongolian Minerals.

test work for Syrah (Mozambique) on the High pressure Grinding Roll (HpGR) vs. Conventional Crusher, and Column Cell vs. Conventional Cells were completed.

the Industrial Minerals unit of Small-Scale Mining and Beneficiation division (SSMB) has continued with research into new product designs for ceramics and have developed three new prototypes. these designs will be transferred to groups that have been trained to manufacture as part of their product range. Research is still in progress into developing a glaze used for ceramic products made out of phosphor.

A study on cultured granite was

undertaken and staff was trained on the manufacturing of products. Further research was done during the year into the technique used together with a market assessment of the products required. the process of producing cultured granite was then successfully transferred to a group of 12 beneficiaries in Phakisa, Free State. this group is operating at the Harmony Mine Industrial Centre and is now able to produce cheaper tombstones and table tops using cultured granite. the initiative was also supported by the Free State Development Corporation (FDC) and the local Development Agency (lDA).

FERROUS METALS Ferrous metals are those which contain iron, such as nickel, steel and iron. these metals are highly durable and cost effective and have a relatively low electrical and thermal conductivity. Ferrous metals have applications in building structures, the automotive industry and even consumer products. the physical Metallurgy group at AMD are involved in the energy efficiency and recycling in South African Foundries (effSAFound) project which deals with investigating the thermo mechanical properties of High chrome cast iron for the South African Foundry Industry.

the effSAFound project is a collaboration between the Department of trade and Industry (DtI), National Foundry technology Network (NFtN), Mintek, Ametex and foundries in South Africa. A consortium was established and in an exercise to increase competitiveness between South African foundries, the effSAFound project allows all members of the consortium to use the MAGMA 5 casting process simulation software and perform the simulation of complete casting and post casting process.

During August and September 2013, the AMI - FMDN project team had successful technical discussions with transnet Freight Rail (tRF - a division of transnet limited and a user of both cast and forged wheels/tyres) and eskom (the high temperature and energy materials user). Subsequently, tFR have supplied the team with a set of cast and forged rail wheels together with an axle for metallurgical characterisation. Also, under the AMI-

pMDN project, the commissioning of the gas atomiser has been completed and the production of spherical powders of pGM-containing ti-Al alloys with tungsten or vanadium is being investigated.

the application for funding to commercialise the umpaball™ technology has been approved by technology Innovation Agency (tIA) and the Mou between Mintek and Autocast has been signed. under the supervision of Mintek, three batches of grinding balls have been produced at the Autocast Foundry premises in port elizabeth. A batch containing 70mm diameter balls has been delivered to Mintek in preparation for Marked Ball testing.

the Metals technology Centre (MtC) has set up an important, strategic materials characterisation project on behalf of DCD Ringroller and Actom (supplier of forged rail wheels from China). the Foundry and Corrosion sectors at MtC executed a strategic alloy development project on behalf of Impala platinum and engineering Systems. Impala has an abundance of Ruthenium (Ru) and expressed the need to beneficiate it through alloy development.

the Iron (Fe) ore test work at the Minerals processing Division (MpD) looks promising and has picked up considerably, focussing on liberian, Angolan and Brazilian material. Bulk test work has been signed up for 2014, for Vetria (Brazilian deposit), based on the scoping and feasibility work conducted previously. owing to the complexities of fine Fe ore processing, this will be a central focus going forward. Fe ore requests from exxarro have been prominent owing to the successful laboratory application of tungsten Carbide, DMS (?) and Mintek’s ability to cut at densities >4.0g/cm3.

With large reserves of fine chromite available either in the form of uG2 tailings or in its natural state; interest in further upgrade and recovery has been seen. Novel approaches in terms of magnetic separation (introduction of Slon technology) and gravity separation (reflux classifier) are being investigated. If successful this will significantly increase Chromium resources and economic growth.

RARE EARTHSMintek has enhanced the reputation of its competence in rare earth processing internationally through high quality conference presentations as well as excellent references from local and international clients. the Mintek paper presented at the CoM 2013 Ree Symposium in Canada, has been selected to be published in the peer reviewed Canadian Metallurgical Quarterly, while Avalon Rare Metals have been very complimentary in their investors presentations and media releases about their cooperation with Mintek and the process development work done by Mintek for them. the Hydrometallurgy Division (HMD) also showcased its Rare earth element (Ree) processing expertise internationally with a presentation of a paper at the MS&t ’13 (Materials Science and technology) Conference in Montréal, Canada from 27 October – 31 october 2013. this paper was well accepted and attracted much interest. It is expected that a positive spinoff of this interest will be seen as soon as the Ree projects that were put on hold due to the poor business climate in 2013 are resumed.

the work on the Ree pilot separation facility has progressed well and the plant is complete. Due to insights gained from test work done for a large Canadian client, the scope of the pilot plant had been expanded to include a feed preparation stage prior to refining. The process development work on the cracking, extraction and impurity removal has been completed in parallel and the main focus remains on developing a flow sheet that can accept material from a variety of sources and produce a feed of consistent composition for the separation process.

Comprehensive process simulations and mass balance calculations had been done to investigate the influence of different feed sources on the flow sheet design of the central cracking and purification facility. These models can now be used to do scenario planning in order to evaluate the Capex and opex impacts of the potential feed stocks on a centralised Ree processing facility. to this end the Steenkampskraal’s Rare earth carbonate material is currently being treated in a pilot campaign in a joint project with Mintek. the entire circuit as designed from the laboratory phase of work is being followed with the

aim of confirming design parameters for the full-scale plant. Improved Ree concentrate grade on the lofdal project has been attained through the usage of Vertical High Gradient pulsed Magnetic Separator (VHGpMS).

Due to the continued concern about Ree availability, there has been continued interest in South Africa’s Rare earth deposits. ores from Zandkopsdrift, Steenkampskraal and lofdal have been investigated to assess their upgrading potential and to optimise the metallurgical flowsheet.

Ree projects have reached feasibility and bankable stages with continued work on ores from Steenkampskraal and lofdal. X-ray sorting of Ree ores has shown that it is possible to reject barren waste and results obtained are comparable with dense media separation (DMS).

PROCESS MONITORING AND CONTROLIn furthering Mintek’s efforts to provide direct benefit to Southern Africa minerals industry through the development and application of process control technologies, the Measurement and Control division at Mintek has implemented several large solutions that were shown to realise substantial benefit. In addition, MaC successfully commercialised a number of new technologies, produced several new product prototypes, and on the technology development front, excellent progress was made with prototyping of new technologies to be used for auto-modelling and adaptive control.

Mintek presented demonstration results for three of its new technologies at international and local conferences during the year. A paper explaining the benefits of Mintek’s patented SlipCam machine-vision based Submerged-Arc furnace electrode slipping measurement device was presented at the tri-annual Infacon XIII Conference in Almaty Kazakhstan in July 2013. the device was also selected as a finalist for the prestigious NStF-BHp Billiton Awards for 2013 under the category: “Research leading to Innovation by a team or individual in a Corporate organization or Institution” earlier on in the year. Results showing improvement in recovery of both copper and lead in excess of 2% at a Base Metals concentrator through the introduction of Mintek’s FloatStar Grade-Recovery


optimiser (FSGRo) were presented at procemin 2013 in Chile in october, and even more impressive results from the same technology implemented on BCl’s Base Metals concentrator in Botswana was presented at Metplant in Australia. the commissioning of the FSGRo technology is underway at Northam’s local greenfield Booysendal platinum concentrator - this will be the first FSGRO installation on a PGM concentrator using the BlueCube MQi grade analyser technology. lastly, at this year’s platinum 2013 conference held in November 2013, demonstration test results showing the improved grade control provided through Mintek’s new FloCam visual monitoring system were presented.

During the year, large installations of Mintek’s world leading FloatStar level Stabiliser (FSlS) and MillStar technologies were also completed at a number of Southern African concentrators, including a FSlS in Zimbabwe, a full MillStar and FSlS for Mopani Copper Mines in Zambia, and FSlS and FloatStar Flow optimiser at Northam’s Booysendal project near lydenburg. In terms of impact, these control technologies often realise improvements in recovery of well in excess of 1%. Such an improvement on a typical pGM plant translates to increased revenue of the order of R20m per year, without any notable

increase in operating cost. Further to the FloatStar and MillStar technologies, strong sales of Mintek’s Cynoprobe online cyanide concentration measurement instrument were experienced, with 15 Instruments being sold during the year, including four to Burkina Faso, one in Ivory Coast, one in Ghana, and five to Australia. Mintek’s FurnStar submerged-arc furnace controller was also installed on a ferrochrome furnace in turkey and on Glencore lion’s new ferrochrome furnace near tubatse.

In terms of the development and commercialisation of new products, several licenses of Mintek’s Robust Nonlinear Model predictive Control (RNMpC) algorithm, applied to stabilise the discharge end the milling circuit, were sold during the year. the RNMpC intellectual property (Ip) is the first IP at Mintek to be successfully commercialised under the Intellectual property Rights from publicly Financed Research and Development Act (Act No 51 or 2008), and apparently only the second such instance in South Africa. the RNMpC control technology is also on trial at two local gold plants

for Mill power optimisation and is being configured to provide Uranium leaching control at another local plant. A further product successfully commercialised during the year is Mintek’s Cylas device. Cylas is an online laser-based distance meter used for measuring the hydrocyclone underflow flare angle in order to ensure these critical process units are operating correctly. Cylas was produced as a prototype in the previous year and sold to both local and international clients during the year.

In terms of advanced process control technology development, excellent progress was made with prototyping of new technologies to be used for auto-modelling and adaptive control. this is the first milestone in Mintek’s medium term strategy to enable their advanced control systems to perform optimally for longer periods unattended. Currently, these sophisticated control systems require retuning once or twice a year as process conditions and the responses of plant actuators change. the auto-modelling and adaptive control will enable the controllers to perform “self-tuning” when they detect conditions have changed or performance has deteriorated. The benefit to industry is that a more consistent optimum level of performance will be maintained over longer periods, despite process changes, and without incurring .

WATER AND ENERGyA suitable test site for demonstrating the SAVMIN™ technology had been secured on the West Rand and an agreement with the site owners has been finalised. Procurement of mechanical equipment is complete while the assembly of equipment at Veolia workshops is 75% complete. the construction of the demonstration plant is currently progressing well although a plan to mitigate expected delays in the installation due to the design of the cyclone circuit and site interface circuits has been formulated. Significant time savings from on-site fitting is expected and a staged installation and commissioning process will be followed in order to recover some of the lost time. In order to compensate for delays in the test work start date, an extension to the original Gold one site use agreement has been negotiated to be until May 2015.

An exciting new approach to the recycling of Al(oH)3 is also under

investigation in collaboration with Veolia and shows good promise to lower the operational costs of the SAVMIN™ technology even further. Although this involves only the substitution of the current Al(oH)3/CaSo4 separation device with a device proven in the water treatment industry, there has been delays due to an in depth process review and the fact that an important component in the Al(oH)3 recovery process was shown to be unsuitable.

through the training of ceramic and pottery manufacturers (CpM), Mintek developed the idea of drying the clay products produced by their project beneficiaries by using solar energy as opposed to electricity. Since these CpMs are located in various areas that are very warm and dry and also exposed to a great deal of solar energy, the idea of drying out their products by using the sun’s heat seemed plausible. A low cost Solar oven was successfully designed and manufactured and the technology was transferred to a group of potters in Giyani.

there is an overwhelming need for renewable and green energy in all industrial sectors. However, industries are mindful over changes in energy costing. Ferroalloy producers are no exception but have expressed keen interest towards investigating the prospect of energy recovery systems, provided there are minimal disturbances to the current processes of tapping and casting. the MaC division investigated the feasibility of recovering thermal energy from hot tapped ferroalloy metals using solid state thermoelectric generators. Currently, there is a significant amount of latent heat being lost to the environment. therefore, a laboratory-scale setup was constructed to test readily available thermoelectric devices and thereby determine the practical viability of the technology. the results show that these devices generally suffer from very low efficiencies. There are a few reports of highly efficient thermoelectric devices but these are in reference to highly specialised proprietary devices. When considering existing electricity prices, energy capture systems provides a viable alternative and are rapidly gaining popularity within the industrial sector. As the technology evolves it will become a more attractive prospect in future applications.

BuSINeSS DeVelopMeNt provides support to Mintek’s business units and focuses on the management and commercialisation of intellectual property, corporate marketing, mineral economics and policy. Mintek provides support to the DMR and other government departments on among others, mineral policy and development and rehabilitation of derelict and ownerless mines. Mintek’s Office for technology transfer provides centralised coordination, oversight and support to the technical divisions who in turn are responsible for the creation and commercialisation of intellectual property. The Office for technology transfer interfaces with the National Intellectual property Management Office (NIPMO), records and monitors Mintek’s Ip portfolio and Ip training, and manages the patent and trademark register.

During this year, Mintek filed 8 patents and registered 11 discoveries.

Rehabilitation of derelict and ownerless mines

the DMR and Mintek concluded an agreement on 6 June 2013 for Mintek to continue to manage rehabilitation of certain derelict and ownerless mine sites for a further 3-year period.

MINteK ANNuAl RepoRt 2014 BuSINeSS DeVelopMeNt, etC.28

During the course of the year the Strelley Mine revegetation project was completed. However, Mintek was able to award three other tenders - two in Mafefe area in the limpopo province (Mahlatjane and Dithabogong) and one near lusikisiki in the eastern Cape (lusikisiki Quarry Wall). Site establishment and construction activities are underway on all three sites. Mintek also completed concept designs for three other projects in the Mafefe area (Cork, Ga-Madiba and Mang-le-Mang) and submitted these to the DMR for approval. three other asbestos sites in the Northern Cape (ettrick/exit, Masaneng and Buisvlei) are currently being surveyed, with a view to undertaking the designs and publishing the tenders during the first two quarters of next year.

A substantial amount of work was done on the osizweni project in the form of attending and contributing to the KwaZulu-Natal Department of Co-operative Governance and traditional Affairs (CoGtA) task meetings, and preparing the next stage of the design for the rehabilitation for the osizweni coal and clay pit.

the majority of programme spending has been directed to planning and procurement of services to the programme, but spending on rehabilitation project implementation will increase rapidly next year when construction work commences.

the Mineral economics and Strategy unit (MeSu) also continued to contribute to Mintek’s projects on Northern Cape gemstones and contributed a market study report on tigers eye.

Support to rural and marginalised communities through training and SMME development

received certificates from the Mining Qualifications Authority (MQA) after successfully completing their level 2 Jewellery Manufacturing learnership and five for completing a Level 2 skills programme on the Manufacturing of Indigenous Jewellery. twenty learners have also been selected and registered for a level 3 learnership at Mintek.

pottery training has progressed smoothly during the year with fifteen learners being trained in the township of Wattville, south of Benoni (ekurhuleni Metropolitan Municipality) and five more in Virginia in the Free State. the Gauteng Department of Sports, Arts & Culture awarded Mintek another contract to further up-skill learners in Wattville in intermediate/advanced pottery training. As part of the effort to create more jobs, the same department awarded Mintek a contract to train ten learners in Glass Bead Manufacturing in Sharpeville.

the second year of the three-year contract with the National lotteries Board has been successfully completed. the Masibambane Co-operative in De Aar, Northern Cape consists of six beneficiaries, mainly youth that were trained in pottery manufacturing. the building that was donated to the group by the local Municipality required refurbishment and the funding received by Mintek was used for this.

three SSMB staff have been trained on the manufacturing of cultured granite. Cultured granite is “artificial” granite made of polymer, fillers and other material but is made to look and feel like real granite. the mixture is shaped, caste and hardened before it is ready for use. Cultured granite is less expensive than granite and hence creates several market opportunities for products like countertops, tombstones, flooring etc. Further research was done during the year into the technique used together

with a market assessment of the products required. the process of producing cultured granite was then successfully transferred to a group of twelve beneficiaries in Phakisa, Free State, at the Harmony Mine Industrial Centre. the initiative was also supported by the Free State Development Corporation (FDC) and the local Development Agency (lDA).

the Gauteng enterprise propeller (Gep) entered into a Mou with Mintek to collaborate in the setup of “manufacturing hubs” consisting of production units trained in glass bead making, jewellery, pottery and cultured granite.

the second year of the Gemstone project in the Northern Cape resulted in the assessment of a number of buildings for the set-up of gemstone training and beneficiation centres. training of twelve learners in Jewellery Manufacturing and another two learners in Gemstone Cutting and polishing continued in prieska, centres will also be set-up in upington and Kimberley.

the Small enterprise Development Agency (SeDA) awarded Mintek a contract for the training of a group of twelve small scale miners in Mokopane on surface mining and quarrying.

Technology for Jewellery Manufacturing

the SSMB division researched and developed appropriate technologies required by rural communities and small scale miners to manufacture products from minerals and other waste materials. the objectives of the project was to create home-made crackled quartz infused with metallic dye, to be able to use different colour dyes and to increase the number of technologies currently used by jewellers and crafters. tests were performed and results indicated that

the best temperature to crackle in is 500°C which can only be achieved using dry crackling. It was shown that the longer the crystal is immersed in the water dye bath the deeper and richer the colour would become. Changing the colour of the quartz proved successful and this was achieved using the dry crackling method. the home-made crackled quartz technology has thus been successfully adapted, and may be used in jewellery to add variety in the pieces produced for sale.

the next step in the process would be to transfer this technology to jewellery groups that are being trained on jewellery manufacturing. Before this, however, a few confirmations will need to be done. these would include testing for strength of the samples and deciding which would be the best way to finish the crystals off. This would be a choice between faceting to give a glossy appearance and polishing or tumbling to achieve a more natural look.

PEOPLEEmployee Relations

the employee Relations unit maintains a harmonious working relationship within Mintek by implementing a first line labour relations consulting service to managers and employees, ensuring that any form of dispute is handled effectively so that it does not escalate to a level that requires external mediation. During the past year, Mintek operated in an environment where there was no recognized labour union. this was a result of the continued loss of membership by the National union of Mineworkers (NuM), which was the only union that had been recognized at Mintek on the strength of their membership figures. The membership threshold for recognition is 50%+1 and the NuM’s membership at the end of the financial year was 7%.

Although there was a decrease in the number of disciplinary cases that were dealt with during the last quarter, Mintek averaged around 26 disciplinary cases, the majority of which were cases of misconduct and absenteeism, with a small number of labour Court cases. Disciplinary cases around absenteeism steadily decreased over the year as a result of progressive discipline in conjunction with an employee Assistance programme (eAp).

Attracting and Retaining People

In an increasingly changing and competitive job market, employees expect more from their jobs than


financial benefit alone. More so, employees look for opportunities that are meaningful and beneficial to society. to be an employer of choice, Mintek focused on supporting employees in their career development, paying employees competitively, creating a safe work environment for all and offering stimulating work.

the number of employees that resigned from Mintek remained steady throughout the year. the category that had the highest number of resignations was that of “skilled technical, academically qualified, junior management and supervisors”. However, this is also the largest employment category. the majority of these resignations were people who work in support services but who were categorised in this occupation level according to the Department of labour’s categorisations. labour turnover for the year amounted to 8.9% in the “skilled technical, academically qualified, junior management and supervisors” category of which only 2.6% were in the category of “researchers and scientists”. the most cited reasons given in exit interviews were the quest for innovation and pursuit of further studies and to a lesser extent a lack of career growth

Developing People

Mintek’s human capital development interventions include an inward focused skills development, training and development of employees, as well as interventions that have an external

focus aimed at developing science and engineering students. Mintek provides undergraduate/postgraduate bursary programmes for full-time students; as well as internships and mentoring.

Mintek continues to develop its talent pipeline through the award of undergraduate (uG) and postgraduate (pG) bursaries to students undertaking full time studies in Science and engineering disciplines. For the past year, 30 uG and 15 pG bursaries were awarded and absorption rates of 100% were achieved for both uG and the Master’s component of pG. No phD’s were absorbed as they have not completed their studies yet. Mintek continues to focus on reaching female student engineers and student scientists, as well as African students. In the full-time uG studies 72% were African while 67% were female. the pG student profile turned out similar, with 67% bursars being African, and 58% female.

to mitigate the long term impact of the ageing workforce, Mintek encourages its employees to undertake part time pG studies and during the year awarded 74 uG and 55 pG bursaries. At uG level, 86% of bursaries were awarded to Africans and 49% to females, whilst at pG level, 80% of bursaries were awarded to Africans and 47% to female.

A total of R5 300 576 which represented 2.1% of payroll was spent on training programmes provided to employees for the year. of the total spend, more than

Mintek implemented a number of programmes in partnership with different organizations. these included the DSt/NRF Internship programme, an annual programme facilitated by the Department of Science and technology (DSt) through the National Research Foundation (NRF). under this programme Mintek hosted 8 interns.

the DSt-NRF professional Development programme (pDp) is a critical initiative, addressing the declining numbers of students registering for full-time postgraduate studies. the programme entails hosting full-time Masters and Doctoral students at Mintek on a fixed-term basis so that the students conduct their research using Mintek equipment and resources. there were 7 fellows in the programme during the year.

Scheme, known as Work Integrated learning (WIl) to give practical learning to S4 students from universities of technology. this practical learning, forms part of the assessment to qualify for a Diploma. A total of 103 candidates took part in the programme of which 6.7% were absorbed as employees.

Mintek and the MQA, implemented an MQA/Het programme, which provided opportunities for unemployed graduates to gain industry experience. there were more than 20 interns in the programme.

the Advanced Material Division received a grant of R3 million to support 41 interns in the DSt/tAp Foundry programme.

Mintek also worked with the MQA and established an on-site Artisan learnership programme (Alp). At the end of the year 3 there were 15 Alp candidates which comprised a combination of 11 internal and 4 external candidates. one internal candidate resigned. of the 4 external candidates, 2 completed the programme and 2 are still continuing in the programme.

Transformation and Diversity

Mintek continues to make excellent progress with regards to transformation in the work place. the table below presents the occupational levels overview at the end of the year.

Employees with Disabilities

the number of employees living with disabilities increased, following a campaign to ascertain underlying non-observant mental impairments as defined in the Code of Good Practice on Disability (for example epilepsy, bipolar and partial-sightedness and hearing-impairment). Such claims require medical proof and an examination by the Mintek Clinic Doctor. By the end of the financial year, 2.6% of Mintek employees were people living with disabilities.

HEALTHChemical and physical hazards in the workplace may result in a number of occupational diseases if not controlled. As such, Mintek aspires to achieve zero harm and a healthy and productive workforce through the effective and sustained management of occupational health risks.

Occupational Health

occupational Health Statistics revealed an increase in Spirometry tests, with no significant abnormalities. In terms of Audiometry, there was an increase in the number of tests and a 10% increase in the cases above plH (percentage of Hearing loss). However, none of the cases were associated with Noise Induced Hearing loss because the affected employees have had hearing problems since childhood. only three cases were referred to the Audiologist for confirmation of hearing disability status.

Biological Monitoring

Results for biological monitoring of cobalt, nickel and arsenic were all within the tolerated exposure limits. For uranium, which showed a consistent decrease in the number of samples submitted over the year, all results so far were below 10 µg/l for the divisions that tested.

With regards to out of specification uranium urine analysis, one sample submitted for analysis in November 2013 showed readings of 38.8µg/l. this result was received in January 2014. the employee underwent monthly monitoring of the liver function tests, Kidney function, Full Blood Count and urine Microscopy tests and no abnormalities related to uranium exposure have been detected. the Urine–uranium result for the sample submitted in December was 0.912µg/l.

All the results were far below the occupational exposure limit.

Health Incident Reporting

the Health Incident Frequency Rate (HIFR) is the number of occupational health incidents x 2000 / total man-hours worked by all Mintek staff over the preceding 12 months, expressed as a percentage. Mintek’s HIFR has increased to 0,13.

Wellness

Mintek’s employee wellness programme is a comprehensive programme that includes occupational and primary health management provided under the auspices of the Clinic, as well as an employee Assistance programme (eAp).

the South African National Blood Services (SANBS) visited Mintek three times during the year and a total of 39 employees donated blood during the period. the target for Mintek is 16 blood donors per visit. Screening failures continue to result in between 20% and 25% per SANBS visit.

the Cancer Association of South Africa (CANSA) Shavathon event was held on the 28th February 2014 and a total of R15 328 was donated to CANSA.

During the health awareness week in the first quarter of the year, activities included blood donations, candlelight memorial service, health screening and an HIV Counselling and testing (HCt) campaign. participation of employees in the HCt campaign continues to increase and this year 314 employees were screened for HIV. other wellness events during the year included a weight-loss challenge and AIDS Day event, which formed part of the Mintek annual Imbizo programme for staff.

Employee Assistance

the employee Assistance programme (eAp) aims to improve employee and organisational effectiveness. eAp cases throughout the year comprised management referrals, self-referrals and coaching, guiding and advising of supervisors.

employees who voluntarily approached the eAp for assistance reported challenges that included marital and relationship problems, trauma and bereavement, job stress and performance related counselling, ill health issues and excessive use of sick leave, substance abuse interventions and parenting challenges.

SAFETyMintek strives to have an injury-free workplace and as such, the safety of all those who work for us is one of the main priorities, beyond the point at which Mintek achieves zero harm to its employees.

the lost time Injury Frequency Rate (ltIFR) represents the number of lost time injuries x 2000 (the assumed number of working hours in one man year) / total man-hours worked by all Mintek staff over the preceding 12 months, expressed as a percentage.

There were five lost time injuries during the year some of which were caused by defective equipment, inadequate training and inspection, and negligence. the incidents caused torn ligaments in an ankle, lacerations to a leg and fingers and minor bruises. In all instances, a lost cause analysis is conducted and addressed. the overall ltIFR achieved at the end of the year was 0.5, which was within the target of less than 1.

the public Dissatisfaction Frequency Rate (pDFR) is the number of public complaints received by Mintek over the preceding 12-month period. Some of the complaints included the noise from a high pitched whistling noise. this was corrected as the pump was switched off at 18:00 and a time switch was installed to prevent noise at night. other noise complaints centered around the Bay 1 extraction fan and for this a new attenuator was installed in the extraction fan.

PUBLICATIONS, CONFERENCES AND STAFF PAPERS

puBlISHING A ReSeARCH pApeR in a journal or conference is an important activity within Mintek as it allows our researchers to network with other scholars and to further refine their ideas and research. these contributions are valuable contributions to the discourse in every field of inquiry and to the culture of all creative fields. Local and international conference attendance help researchers feel integrated with the research community. At conferences, researchers meet people who are interested in the same topic of research and discuss theoretical and methodological ideas. By attending these conferences, researchers also identify business opportunities for Mintek and enhance the organisation’s reputation for high quality research. Against this background, Mintek maintains a high level presence at relevant conferences locally and abroad. the following included some of Mintek’s publications, conference attendance and other related activities during the year.

• Eight (8) papers were presented at the 5th International Conference on Nanoscience and Nanotechnology hosted by the South African Nanotechnology Initiative (SANi).

• Isabel Geldenhuys delivered a plenary address on chromite smelting in DC arc furnaces at the 13th International Ferro-Alloys Congress (Infacon XIII) in Almaty, Kazakhstan – the pre-eminent technical conference in the field of ferro-alloy smelting. this conference series was initiated by Mintek (then the National Institute for Metallurgy), SAIMM, and FAPA, and was first held at Mintek in 1974.

• Rodney Jones gave a plenary address on electric smelting in southern Africa at the european Metallurgical Conference held at Weimar, Germany, and also spoke about the pyrometallurgical recovery of nickel at the same conference.

• Another significant conference this year was a Symposium on pyrometallurgy in honour of David G.C. Robertson, held in San Diego, California, uSA. Rodney Jones was one of the conference organizers and editors of the proceedings – published as ‘Celebrating the Megascale’ by tMS. Rodney Jones and Quinn Reynolds both presented invited papers at the conference.

• An MPD staff member presented at the 11th International DMs powders Symposium in February 2014.

• Two MPD Senior Staff members presented on a method of modelling of physical processes using data derived from mineralogical characterization of fine ores at the Iron Ore Beneficiation

Africa, International Mining and Metal Series Conference.

• HMD presented four papers at the ALTA perth 2013 uranium, gold and Ree conferences. All papers, especially the gold and Ree papers generated much interest and prompted a number of enquiries from prospective clients as well as requests for possible collaboration such as the approach from the CSIRo in perth.

• HMD presented four papers at the SAIMM Base Metals 2013 and the quality of these papers was such that Mintek received a special letter of commendation from the SAIMM.

• The HMD paper presented at the COM 2013 Ree Symposium in Canada has been selected to be published in the peer reviewed Canadian Metallurgical Quarterly

• The HMD paper presented at the SAIMM precious Metals 2013 Conference was selected to be published in the Journal of the South African Institute of Mining and Metallurgy.

• The ASD Symposium, held on 18 october 2013, followed the theme “Challenges and Solutions in Analytical Chemistry”. the program included nine highly informative presentations from industry representatives, academic professionals and analytical technology suppliers.

• Three staff members from MNL presented at the SAIMM Young professionals Conference. this conference is a good starting experience for conference presenting and networking in a professional capacity for Mintek’s young scientists.

• MNL played a significant role at the Kimberley Process Certification Scheme’s plenary conference, held in November 2013. the MNl team contributed to an administrative decision submitted by the Working Group of Diamond experts and accepted by plenary, which will allow import of conflict diamonds, particularly from the Côte d’Ivoire, for the purposes of fingerprinting research. This is in consultation with the united Nations Group of experts on Côte d’Ivoire.

• Dr Deshenthree Chetty presented a technical talk on X-ray Computed Tomography – Applications in Process Mineralogy during July 2013 at peking university, Beijing, the China university of Geosciences in Beijing, Nanjing university and the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences.

• Three papers and one poster were presented at the Southern African Institute of Mining and Metallurgy (SAIMM) Young professionals Conference held at Monte Casino on 11-13 March 2014. the titles of the papers were “Small Scale Mining: Deficiencies within the sector”, “The elegant solution to safe drinking water challenges in the rural communities” and “Implementation of urban mining training and awareness programmes in Gauteng”. the title of the poster presentation was “technological advancements in the small-scale mining sector”.

• Two papers were presented at the Southern African Institute of Mining and Metallurgy (SAIMM) Mining, environment and Society Conference held at Misty Hills in November 2013.

DIRECTORS’ RESPONSIBILITIES AND APPROvAL

tHe DIReCtoRS ARe ReQuIReD IN teRMS oF tHe puBlIC FINANCe MANAGeMeNt ACt to maintain adequate accounting records and are responsible for the content and integrity of the financial statements and related financial information included in this report.

It is their responsibility to ensure that the financial statements fairly present the state of affairs of the group as at the end of the financial year and the results of its operations and cash flows for the period then ended, in conformity with South African Statements of Generally Accepted Accounting practice and are based upon appropriate accounting policies consistently applied and supported by reasonable and prudent judgements and estimates. the external auditors are engaged to express an independent opinion on the financial statements.

the directors acknowledge that they are ultimately responsible for the system of internal financial control established by the group and place considerable importance on maintaining a strong control environment. to enable the directors to meet these responsibilities, the directors set standards for internal control aimed at reducing the risk of error or loss in a cost effective manner. the standards include the proper delegation of responsibilities within a clearly defined framework, effective accounting procedures and adequate segregation of duties to ensure an acceptable level of risk.

these controls are monitored throughout the group and all employees are required to maintain the highest ethical standards in ensuring the group’s business is conducted in a manner that in all reasonable circumstances is above reproach. the focus of risk management in the group is on identifying, assessing, managing and monitoring all known forms of risk across the group. While operating risk cannot be fully eliminated, the group endeavours to minimise it by ensuring that appropriate infrastructure, controls, systems and ethical behaviour are applied and managed within predetermined procedures and constraints.

the directors are of the opinion, based on the information and explanations given by management, that the system of internal control provides reasonable assurance that the financial records may be relied on for the preparation of the financial statements. However, any system of internal financial control can provide only reasonable, and not absolute, assurance against material misstatement or loss.

In the opinion of the directors the group has adequate resources to continue in operational existence for the foreseeable future. this opinion is based on the 2014 budget and the current financial position of the group.

the external auditors are responsible for independently reviewing and reporting on the group’s financial statements. The financial statements have been examined by the group’s external auditors and their report is presented on pages 52 to 53.

The financial statements set out on page 54 to 74, which have been prepared on the going concern basis, were approved by the directors on 24 July 2014 and were signed on their behalf by:

DIRECTORS’ REPORT

MINteK CoNtINueD to DeMoNStRAte its financial sustainability during the financial year under review despite the difficult economic climate. The ongoing uncertainty and impact on global economic growth has negatively affected the demand for commodities and the industry in which Mintek operates. Changes in Mintek’s surplus margins between 2009/2010 and 2013/2014 have been in line with the substantial shifts in the demand for our products and services which has been a reflection of the volatility of the underlying global and geopolitical factors affecting the mineral resources industry. Mintek’s biggest customer base is predominantly in the South African minerals sector and the chronic labour unrest, work stoppages, poor productivity and price inflation in utilities had a knock on effect on Mintek’s financial results. Our revenue and cash flows are further influenced by changes in the South African Rand due to the geographical diversity of our customer and supplier base. Given the dominant role of the uS currency in our foreign transactions, the depreciation of 14% of the Rand against the US Dollar had an impact on our financial results as the Rand continued its downward trend during 2013/2014 reaching R10.53 to the uS Dollar at the end March 2014. Mintek does not hedge exchange rate fluctuations as we do not believe that active currency hedging would provide long term benefits to our financial performance and position.

Mintek continuously reviews its operating costs focusing on its costing model to ensure that project costs do not spiral out of control over the life cycle of projects. As a result, significant time and resources are devoted to project planning, approval and review processes. Notwithstanding that, our cash generating assets have been adversely affected by changes in markets and industry structures, high energy costs, interruptions in supply, equipment damages and failures and other technical challenges. this has led to increased operational and capital costs and the envisaged returns that were anticipated from the assets not being fully realised.

We contract with a large number of commercial counterparties including customers and suppliers and the ongoing global economic volatility has placed strains on global financial markets, reduced liquidity and adversely affected business conditions generally and our approach in managing credit risk is to ensure that all credit exposures are quantified and strictly managed to prevent financial losses.

The selected financial information below reflects the operations of the Mintek Group and should be read in

conjunction with the 2013/2014 financial statements, together with the accompanying notes on pages 54 to 74.

Income

Mintek group revenue decreased by 2% during the year under review and it amounted to R441.1m (2013:R451.9m). the decrease in revenue is mainly due to the continued reduction in the demand for mining research and equipment damages and operational challenges in Bay 2 that resulted in downtime during the year.

the State Grant contributed 43% (2013: 41%) to the total revenue in 2014, whereas products and Services and Contract Research contributed 36% (2013:31%) and 17% (2013:24%) respectively. total State Grant increased by 2% in 2014 from R192.5m to R196.8million.

Commercial revenue decreased by 4% from R222.6million in 2013 to R213.9million in 2014. this revenue was generated from both local and foreign sales. local sales contributed 61% (2013:58%) and foreign sales contributed 39% (2013:42%) on the total commercial revenue. the decrease in foreign revenue over the last 5 years has been due to the weakening of the Rand and lower growth in the mineral processing, pyrometallurgy and hydrometallurgy fields where fewer large pilot plants were conducted.

other income mainly comprises of interest received from short term investments and rental income. Interest received has been generated as a result of the investment of income received in advance from both government grants and funding for projects from private sector clients and it amounted to R16.8million (2013:R15.6million). over the


past couple of years Mintek has been prudent in managing its cash resources and this has been achieved through investing in higher interest bearing investments so as to achieve higher short term returns.

Expenditure

operating costs decreased by 2% from R454.5million in 2013 to R443.7million. Fees for services decreased significantly by R48.9million to R40.6m. The decrease is due to significant expenditure incurred for the management of the derelict and ownerless mines rehabilitation during the 2012/2013 financial year that was significantly less in the current year under review. the review of the useful life and residual values of property, plant and equipment decreased depreciation by only R2.7million compared to 2013 where the effect of the depreciation decrease was R5.1million.

employees’ costs increase by 14% which is mainly due to increases in inflation and new staff recruited during 2013/2014. the high ratio of remuneration expenditure to revenue is in line with the nature of Mintek operations which is highly labour intensive and requires a highly skilled technical staff complement. this ratio has remained stable between 2009/2010 and 2013/2014 at an average of 60%.

Review of Financial Position

Cashflow

Mintek’s financial position remains strong. Cash resources are a significant portion of total assets (57%) and have increased by 39% in the last financial year due to an

increase in MteF funding and income received in advance from customers. the operations generated a strong cash flow which has been used to finance working capital and capital expenditure requirements. Cash generated by operations amounted to R74.5million compared to the cash utilised in the previous year of R49.8million. this is largely due to the funds received in advance.

this current status supports Mintek’s continued business activities and execution of projects. However Mintek will continue to exercise caution with such investment, given the uncertainty and volatility of the current economic conditions.

Working Capital

Mintek continued to manage its working capital efficiently despite the volatility in global economic conditions. the current ratio has been maintained at 2 for the past 5 years, the cash ratio increased significantly by 11 percent during the year under review where cash and cash equivalents increased from R13.1 m in 2013 to R39 million. Debtor’s days decreased from 69 days in 2012/2013 to 61 days in 2013/2014.

Capital expenditure

Capital expenditure decreased by R18.6 million to R41.1 during the 2013/2014, this was mainly due to fewer acquisitions and replacement of fixed assets in 2013/2014.

the Return on Invested Capital (RoIC) provides an indication of how efficiently Mintek has invested the capital under its control; this ratio remained stable at 4% between 2012/2013 and 2013/2014.

Mintek received funding of R58.5million (2012/2013- R60.4m) in the current year for the purchase of property, plant and equipment. total depreciation increased by R2.9m from the previous year, the increase is due to a decrease in depreciation effect of the review of useful lives and residual values which was less in 2013/2014 (R2.7m) compared to the previous year (R5.63m).


REPORT OF THE AUDITOR-GENERAL SOUTH AFRICA

REPORT OF THE AUDITOR-GENERAL TO PARLIAMENT ON COUNCIL FOR MINERAL TECHNOLOGy (MINTEK).REPORT ON THE CONSOLIDATED AND SEPARATE FINANCIAL STATEMENTS.

Introduction

1. I have audited the consolidated and separate financial statements of Mintek and its subsidiary set out on pages 46 to 66, which comprise the consolidated and separate statement of financial position as at 31 March 2014, the consolidated and separate statement of comprehensive income, statement of changes in equity and statement of cash flow for the year then ended, as well as the notes, comprising a summary of significant accounting policies and other explanatory information.

Accounting authority’s responsibility for the consolidated and separate financial statements

2. the board of directors, which constitutes the accounting authority is responsible for the preparation and fair presentation of these consolidated and separate financial statements in accordance with South African Statements of Generally Accepted Accounting practice (SA Statements of GAAp) and the requirements of the public Finance Management Act of South Africa, 1999 (Act No. 1 of 1999) (pFMA) and the Companies Act of South Africa, 2008 (Act No. 71 of 2008), and for such internal control as the accounting authority determines is necessary to enable the preparation of consolidated and separate financial statements that are free from material misstatement, whether due to fraud or error.

Auditor-general’s responsibility

3. My responsibility is to express an opinion on these consolidated and separate financial statements based on my audit. I conducted my audit in accordance with the public Audit Act of South Africa, 2004 (Act No. 25 of 2004) (pAA), the general notice issued in terms thereof and

International Standards on Auditing. those standards require that I comply with ethical requirements, and plan and perform the audit to obtain reasonable assurance about whether the consolidated and separate financial statements are free from material misstatement.

4. An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated and separate financial statements. The procedures selected depend on the auditor’s judgement, including the assessment of the risks of material misstatement of the consolidated and separate financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the consolidated and separate financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated and separate financial statements.

5. I believe that the audit evidence I have obtained is sufficient and appropriate to provide a basis for my adverse audit opinion.

Opinion

6. In my opinion, the consolidated and separate financial statements present fairly, in all material respects, the financial position of the Mintek and its subsidiary as at 31 March 2014 and their financial performance and cash flows for the

year then ended, in accordance with the SA statements of GAAp and the requirements of the pFMA.

Additional matter

7. I draw attention to the matter below.

Other reports required by the Companies Act

8. As part of my audit of the financial statements for the year ended 31 March 2014, I have read the Directors’ Report, the Audit Committee’s Report and the Company Secretary’s Certificate for the purpose of identifying whether there are material inconsistencies between these reports and the audited financial statements. These reports are the responsibility of the respective preparers. Based on reading these reports I have not identified material inconsistencies between the reports and the audited financial statements in respect of which I have expressed an unmodified opinion. I have not audited the reports and accordingly do not express an opinion on them.

Report on other legal and regulatory requirements

9. In accordance with the pAA and the general notice issued in terms thereof, I report the following findings on the reported performance information against predetermined objectives for selected objectives presented in the annual performance report, non-compliance with legislation as well as internal control. the objective of my tests was to identify reportable findings as described under each subheading but not to gather evidence to express assurance on these matters. Accordingly, I do not express an opinion or conclusion on these matters.

Predetermined objectives

10. I performed procedures to obtain


evidence about the usefulness and reliability of the reported performance information for the following selected objectives presented in the annual performance report of the public entity for the year ended 31 March 2014:

• Research and develop efficient mineral processing technologies and value added products and services: Strategic objective 2 on pages 13 to 14

• Promote the mineral-based economies of rural and marginalised communities: Strategic objective 3 on page 14.

11. I evaluated the reported performance information against the overall criteria of usefulness and reliability.

12. I evaluated the usefulness of the reported performance information to determine whether it was presented in accordance with the National treasury’s annual reporting principles and whether the reported performance was consistent with the planned objectives. I further performed tests to determine whether indicators and targets were well defined, verifiable, specific, measurable, time bound and relevant, as required by the National treasury’s Framework for managing programme performance information (FMppI).

13. I assessed the reliability of the reported performance information to determine whether it was valid, accurate and complete.

14. I did not raise any material findings on the usefulness and reliability of the reported performance information for the selected objectives.

Additional matter

15. Although I raised no material findings on the usefulness and reliability of the reported

performance information for the selected objectives, I draw attention to the following matter:

Achievement of planned targets

16. Refer to the annual performance report on page(s) 13 to 16 for information on the achievement of the planned targets for the year.

Compliance with legislation

17. I performed procedures to obtain evidence that the public entity had complied with applicable legislation regarding financial matters, financial management and other related matters. My findings on material non-compliance with specific matters in key legislation, as set out in the general notice issued in terms of the pAA, are as follows:

AFS and annual report

18. The financial statements submitted for auditing were not prepared in accordance with the prescribed financial reporting framework and as required by section 55(1)(b) of the public Finance Management Act

19. Material misstatements of disclosure items identified by the auditors in the submitted financial statement were subsequently corrected and, resulting in the financial statements receiving an unqualified audit opinion.

Expenditure management

20. the accounting authority did not take effective steps to prevent irregular expenditure, as required by section 51(1)(b)(ii) of the public Finance Management Act.

Procurement and contract management

• Sufficient appropriate audit evidence could not be obtained that a contract was awarded to a supplier whose tax matters have been declared by the South African Revenue Services to be in order as required by the preferential

procurement Regulations.

• The procurement processes did not comply with the requirements of a fair SCM system as per section 51(1)(a)(iii) of the pFMA, in that an award was made to a supplier not based on criteria that is consistent with the original invitations for bids.

Internal control

21. I considered internal control relevant to my audit of the financial statements, performance against objectives report and compliance with legislation. the matters reported below are limited to the significant internal control deficiencies that resulted in the basis for an adverse opinion, the findings on the non-compliance with legislation included in this report.

Financial and performance management

22. Irregular expenditure could have been avoided had management taken care and ensured that approved policies and procedures are adhered to at all times.

23. Non-compliance with laws and regulations could have been avoided had the accounting authority implemented effective controls over monitoring of compliance with laws and regulations.

ACCOUNTING POLICIES FOR THE yEAR ENDED 31 MArCh 2014

1. Presentation of Financial Statements The financial statements have

been prepared in accordance with South African Generally Accepted Accounting practices, the public Finance Management Act and treasury Guidelines. The financial statements have been prepared on an accrual basis in accordance with historical cost basis except for certain assets and liabilities at fair value, and incorporate the principal accounting policies set out below. they are presented in South African Rand.

these accounting policies are consistent with the previous period.

For purposes of these financial statements, all references to ‘Company’ refers to Mintek, the public entity.

1.1 Basis of consolidation The consolidated financial statements

incorporate the financial statements of the company and all entities, controlled by the company.

Control exists when the company has the power to govern the financial and operating policies of an entity so as to obtain benefits from its activities.

All intra-group transactions, balances, income and expenses are eliminated in full on consolidation.

1.2 Property, plant and equipment the cost of an item of property, plant

and equipment is recognised as an asset when:

it is probable that future economic benefits associated with the item will flow to the company; and

the cost of the item can be measured reliably.

property, plant and equipment are initially measured at cost.

Costs include costs incurred initially to acquire or construct an item of property, plant and equipment and costs incurred subsequently to add to, replace part of, or service it. If a replacement cost is recognised in the carrying amount of an item of property, plant and equipment, the carrying amount of the replaced part is derecognised.

land and buildings are carried at revalued amount, being the fair value at the date of revaluation less any subsequent accumulated depreciation and subsequent accumulated impairment losses. Revaluations are made with sufficient regularity such that the carrying amount does not differ materially from that which would be determined using fair value at the end of the reporting period.

When an item of property, plant and equipment is revalued, any accumulated depreciation at the date of the revaluation is restated proportionately with the change in the gross carrying amount of the asset so that the carrying amount of the asset after revaluation equals its revalued amount.

Any increase in an asset’s carrying amount, as a result of a revaluation,

is recognised to other comprehensive income and accumulated in the revaluation surplus in equity. the increase is recognised in other comprehensive income to the extent that it reverses a revaluation decrease of the same asset previously recognised in the Statement of Comprehensive Income.

Any decrease in an asset’s carrying amount, as a result of a revaluation, is recognised in the Statement of Comprehensive Income in the current period. the decrease is recognised in other comprehensive income to the extent of any credit balance existing in the revaluation surplus in respect of that asset. the decrease recognised in other comprehensive income reduces the amount accumulated in the revaluation surplus in equity.

the revaluation surplus in equity related to a specific item of property, plant and equipment is transferred directly to retained earnings when the asset is been utilised.

the useful lives of items of property, plant and equipment have been assessed as follows:

Item Average useful life

Buildings 50 years plant and machinery 5 - 10 years Furniture and fixtures 5 - 10 years Motor vehicles 5 years Office equipment 5 - 10 years It equipment 3 - 5 years the residual value, useful life and

depreciation method of each asset are reviewed at the end of each reporting period. If the expectations differ from previous estimates, the change is accounted for as a change in accounting estimate.

the depreciation charge for each period is recognised in the Statement of Comprehensive Income unless it is included in the carrying amount of another asset.

the gain or loss arising from the derecognition of an item of property, plant and equipment is included in the Statement of Comprehensive Income when the item is derecognised. the gain or loss arising from the derecognition of an item of property, plant and equipment is determined as the difference between the net disposal proceeds, if any, and the carrying amount of the item.

1.3 Intangible assets An intangible asset is recognised when: it is probable that the expected future

economic benefits that are attributable to the asset will flow to the entity; and

the cost of the asset can be measured reliably.

Intangible assets are initially recognised at cost.

expenditure on research (or on the research phase of an internal project) is recognised as an expense when it is incurred.

Intangible assets are carried at cost less any accumulated amortisation and any accumulated impairment losses.

Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognised in the statement of comprehensive income when the asset is derecognised.

Amortisation is provided to write down the intangible assets, on a straight-line basis, to their residual values as follows:

Item Useful life Computer software 3 - 5 years

1.4 Investments in subsidiaries In the Mintek financial statements,

investments in subsidiaries are carried at cost less any accumulated impairment.

the cost of an investment in a subsidiary is the aggregate of:

the fair value, at the date of exchange, of assets given, liabilities incurred or assumed, and equity instruments issued by the company; plus

any costs directly attributable to the purchase of the subsidiary.

An adjustment to the cost of a business combination contingent on future events is included in the cost of the combination if the adjustment is probable and can be measured reliably.

1.5 Financial instruments Classification The group classifies financial assets

and financial liabilities into the following categories:

Financial assets at fair value through the Statement of Comprehensive Income - held for trading

Held-to-maturity investment loans and receivables Financial liabilities measured at

amortised cost Classification depends on the purpose

for which the financial instruments were obtained / incurred and takes place at initial recognition. Classification is re-assessed on an annual basis, except for derivatives and financial assets designated as at

fair value through the Statement of Comprehensive Income, which shall not be classified out of the fair value through the Statement of Comprehensive Income category.

Initial recognition and measurement

Financial instruments are recognised initially at fair value when the group becomes a party to the contractual provisions of the instruments.


the group classifies financial instruments, or their component parts, on initial recognition as a financial asset or a financial liability in accordance with the substance of the contractual arrangement.

For financial instruments which are not at cost through the Statement of Comprehensive Income, transaction costs are included in the initial measurement of the instrument.

Subsequent measurement Financial instruments at cost through

the Statement of Comprehensive Income are subsequently measured at fair value, with gains and losses arising from changes in fair value being included in profit or loss for the period.

loans and receivables are subsequently measured at amortised cost, using the effective interest method, less accumulated impairment losses.

Held-to-maturity investments are subsequently measured at amortised cost, using the effective interest method, less accumulated impairment losses.

Gains and losses arising from changes in fair value are recognised in other comprehensive income and accumulated in equity until the asset is disposed of or determined to be impaired.

Financial liabilities at amortised cost are subsequently measured at amortised cost, using the effective interest method.

Derecognition Financial assets are derecognised

when the rights to receive cash flows from the investments have expired or have been transferred and the group has transferred substantially all risks and rewards of ownership.

Impairment of financial assets At each reporting date the group

assesses all financial assets, other than those at fair value through the Statement of Comprehensive Income, to determine whether there is objective evidence that a financial asset or group of financial assets has been impaired.

For amounts due to the group, significant financial difficulties of the debtor, probability that the debtor will enter bankruptcy and default of payments are all considered indicators of impairment.

Impairment losses are recognised in the Statement of Comprehensive Income.

Impairment losses are reversed when an increase in the financial asset’s recoverable amount can be related objectively to an event occurring after the impairment was recognised, subject to the restriction that the carrying amount of the financial asset at the date that the impairment is reversed shall not exceed what the carrying amount would have been had the impairment not been recognised.

Reversals of impairment losses are recognised in the Statement of Comprehensive Income except for equity investments classified as available-for-sale.

Impairment losses are also not subsequently reversed for available-for-sale equity investments which are held at cost because fair value was not determinable.

Where financial assets are impaired through use of an allowance account, the amount of the loss is recognised in the Statement of Comprehensive Income within operating expenses. When such assets are written off, the write-off is made against the relevant allowance account. Subsequent recoveries of amounts previously written off are credited against operating expenses.

Loans to/(from) group companies these include loans to and from the

holding company and the subsidiary. Loans to group companies are classified

as loans and receivables. loans from group companies are

classified as financial liabilities measured at amortised cost.

Trade and other receivables trade receivables are measured at

initial recognition at fair value, and are subsequently measured at amortised cost using the effective interest rate method. Appropriate allowances for estimated irrecoverable amounts are recognised in the Statement of Comprehensive Income when there is objective evidence that the asset is impaired. Significant financial difficulties of the debtor, probability that the debtor will enter bankruptcy or financial reorganisation, and default or delinquency in payments are considered indicators that the trade receivable is impaired. the allowance recognised is measured at the carrying amount.

the carrying amount of the asset is reduced through the use of an allowance account, and the amount of the loss is recognised in the Statement of Comprehensive Income within operating expenses. When a trade receivable is uncollectable, it is written off against the allowance account for trade receivables. Subsequent recoveries of amounts previously written off are credited against operating expenses in the Statement of Comprehensive Income.

Trade and other payables trade payables are initially measured

at fair value, and are subsequently measured at amortised cost, using the effective interest rate method.

Cash and cash equivalents Cash and cash equivalents comprise

cash-on-hand and demand deposits, and other short-term highly liquid investments that are readily convertible to a known amount of cash and are subject to an insignificant risk of changes in value. these are initially and subsequently recorded at fair value.

Derivatives the Group does not use derivative

financial instruments including forward rate agreements and forward exchange contracts to hedge exposure rate and foreign fluctuations. It is the Group’s policy not to hedge its exposure from foreign currency fluctuations, as it does not consider the impact to be significant. It is the policy of the Group not to trade in derivative financial instruments for speculative purposes.

1.6 Investments Investments consist of short-term

money market instruments initially recorded at cost, which is the fair value of the cash placed with the institution. these investments are surplus funds which are classified as held-to-maturity financial assets. Interest is accrued using the effective interest rate method and included in the Statement of Comprehensive Income on an accrual basis.

1.7 Taxation Current tax assets and liabilities Current tax for current and prior periods

is, to the extent unpaid, recognised as a liability. If the amount already paid in respect of current and prior periods exceeds the amount due for those periods, the excess is recognised as an asset.

Current tax liabilities/(assets) for the current and prior periods are measured at the amount expected to be paid to/ (recovered from) the tax authorities, using the tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period.

the company is exempt from paying Income tax in terms of section 10(1) CA(i) of the Income tax Act no.58 of 1962, but registered for VAt. Mindev is registered for Income tax.

the tax currently payable is based on taxable profit for the financial year. Mindev’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted at the financial year end date.

1.8 Irregular, fruitless and wasteful expenditure

Irregular expenditure means expenditure incurred in contravention of, or not in accordance with, a requirement of any applicable legislation, including:

the public Finance Management Act; or,

Any provincial legislation providing for procedures in that state owned entity.

Fruitless and wasteful expenditure means expenditure that was made in vain and could have been avoided had reasonable care been exercised. All irregular, fruitless and wasteful expenditure is charged against income in the period in which they are incurred.

1.9 Financing costs Interest in Mintek arises from bank

overdraft, creditors and post retirement


medical aid liability. Financing costs are recognised in the statement of comprehensive income in the period in which they are incurred.

1.10 Leases A lease is classified as a finance lease

if it transfers substantially all the risks and rewards incidental to ownership. A leases classified as an operating lease if it does not transfer substantially all the risks and rewards incidental to ownership.

Finance leases – lessee Finance leases are recognised as

assets and liabilities in the Statement of Financial position at amounts equal to the fair value of the leased property or, if lower, the present value of the minimum lease payments. the corresponding liability to the lessor is included in the Statement of Financial position as a finance lease obligation.

the discount rate used in calculating the present value of the minimum lease payments is the company’s incremental borrowing rate.

the lease payments are apportioned between the finance charge and reduction of the outstanding liability. The finance charge is allocated to each period during the lease term so as to produce a constant periodic rate on the remaining balance of the liability.

Operating leases - lessor operating lease income is recognised

as an income on a straight-line basis over the lease term.

Initial direct costs incurred in negotiating and arranging operating leases are added to the carrying amount of the leased asset and recognised as an expense over the lease term on the same basis as the lease income.

Income for leases is disclosed under other operating income in the Statement of Comprehensive Income.

Operating leases – lessee operating lease payments are

recognised as an expense on a straight-line basis over the lease term. the difference between the amounts recognised as an expense and the contractual payments are recognised as an operating lease asset.

this liability is not discounted.1.11 Inventories Inventories are measured at the lower

of cost and net realisable value on the weighted average cost method.

Net realisable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale.

the cost of inventories comprises of all costs of purchase, costs of conversion and other costs incurred in bringing the decrease/(increase) in inventories to their present location and condition.

the cost of inventories of items that are not ordinarily interchangeable and goods or services produced and segregated for specific projects is

assigned using specific identification of the individual costs.

When inventories are sold, the carrying amounts of those inventories are recognised as an expense in the period in which the related revenue is recognised. the amount of any write-down of inventories to net realisable value and all losses of inventories are recognised as an expense in the period the write-down or loss occurs. the amount of any reversal of any write-down of inventories, arising from an increase in net realisable value, are recognised as a reduction in the amount of inventories recognised as an expense in the period in which the reversal occurs.

1.12 Impairment of assets the group assesses at each end of

the reporting period whether there is any indication that an asset may be impaired. If any such indication exists, the group estimates the recoverable amount of the asset.

Irrespective of whether there is any indication of impairment, the group also:

tests intangible assets with an indefinite useful life or intangible assets not yet available for use for impairment annually by comparing its carrying amount with its recoverable amount. this impairment test is performed annually.

If there is any indication that an asset may be impaired, the recoverable amount is estimated for the individual asset. If it is not possible to estimate the recoverable amount of the individual asset, the recoverable amount of the cash-generating unit to which the asset belongs is determined.

the recoverable amount of an asset or a cash-generating unit is the higher of its fair value less costs to sell and its value in use.

If the recoverable amount of an asset is less than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount. that reduction is an impairment loss.

An impairment loss of assets carried at cost less any accumulated depreciation or amortisation is recognised immediately in profit or loss. Any impairment loss of a revalued asset is treated as a revaluation decrease.

the company assesses at each reporting date whether there is any indication that an impairment loss recognised in prior periods for assets may no longer exist or may have decreased. If any such indication exists, the recoverable amounts of those assets are estimated.

A reversal of an impairment loss of assets carried at cost less accumulated depreciation or amortisation other than goodwill is recognised immediately in the Statement of Comprehensive

Income. Any reversal of an impairment loss of a revalued asset is treated as a revaluation increase.

1.13 Share capital and equity An equity instrument is any contract

that evidences a residual interest in the assets of an entity after deducting all of its liabilities.

1.14 Employee benefits

Defined contribution plans Payments to defined contribution

retirement benefit plans are charged as an expense as they fall due.

Payments made to retirement benefit schemes are dealt with as defined contribution plans where the group’s obligation under the schemes is equivalent to those arising in a defined contribution retirement benefit plan.

For defined contribution plans, the Group pays contribution to privately administered pension insurance plans on a contractual basis. the Group has no further payment obligations once the contributions have been paid. the contributions are recognised as employee benefit expense when they are due.

Defined benefit plans Actuarial valuations are conducted

on an annual basis by independent actuaries separately for each plan.

Actuarial gains and losses are recognised in full in the reporting period it relates to and is the excess over the greater of the present value of the past service obligation at the reporting period before deducting the present value of assumed assets at the same date.

Valuations of these obligations are carried out annually by independent, qualified actuaries using the appropriate mortality tables, long-term estimates of increases in medical costs and appropriate discount rates.

Consideration is given to any event that could impact the funds up to the end of the reporting period where the interim valuation is performed at an earlier date.

past service costs are recognised immediately to the extent that the benefits are already vested, and are otherwise amortised on a straight line basis over the average period until the amended benefits become vested.

the liability recognised in the Statement of Financial position in respect of the defined benefit pension plans is the present value of the defined obligation at the Statement of Financial position date less the fair value of plan assets, together with adjustments for unrecognised past-service costs. the defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method.

prepaid contributions are recognised as an asset to the extent that a cash refund or a reduction in the future payment is available.


the Group has an obligation to fund the medical aid benefits of all its past employees and dependents of past employee who retired or were in the employment of the Group prior to 1 January 2000. the plan liability is unfunded and fully provided for in the financial statements. The Group uses the projected unit credit actuarial method to determine the present value of its past service cost. General increases to medical aid contributions were estimated taking into account the projected future changes in the cost of medical services resulting from both inflation and specific changes to medical costs.

1.15 Provisions and contingencies

provisions are recognised when: the group has a present obligation as a

result of a past event; it is probable that an outflow of resources

embodying economic benefits will be required to settle the obligation; and

a reliable estimate can be made of the obligation.

the amount of a provision is the present value of the expenditure expected to be required to settle the obligation.

Where some or all of the expenditure required to settle a provision is expected to be reimbursed by another party, the reimbursement shall be recognised when, and only when, it is virtually certain that reimbursement will be received if the entity settles the obligation. the reimbursement shall be treated as a separate asset. the amount recognised for the reimbursement shall not exceed the amount of the provision.

provisions are not recognised for future operating losses.

If the company has a contract that is onerous, the present obligation under the contract shall be recognised and measured as a provision.

After their initial recognition contingent liabilities recognised in business combinations that are recognised separately are subsequently measured at the higher of:

the amount that would be recognised as a provision; and

the amount initially recognised less cumulative amortisation.

Contingent assets and contingent liabilities are not recognised. Contingencies are disclosed in note 24.

1.16 Government grants Government grants are recognised

at fair value when there is reasonable assurance that:

the group will comply with the conditions attaching to them; and

the grants will be received. Government grants are recognised as

income over the periods necessary to match them with the related costs that

they are intended to compensate. A government grant that becomes

receivable as compensation for expenses or losses already incurred or for the purpose of giving immediate financial support to the entity with no future related costs is recognised as income of the period in which it becomes receivable.

Government grants related to assets, including nonmonetary grants at fair value, are presented in the Statement of Financial position by setting up the grant as deferred income or by deducting the grant in arriving at the carrying amount of the asset.

Grants related to income are presented as a credit in the Statement of Comprehensive Income (separately).

Where a loan is received from government at below market interest rate, the difference between the fair value of the loan and the amount received is recognised as a government grant.

1.17 Revenue Revenue from the sale of goods is

recognised when all the following conditions have been satisfied:

the group has transferred to the buyer the significant risks and rewards of ownership of the goods;

the group retains neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold;

the amount of revenue can be measured reliably;

it is probable that the economic benefits associated with the transaction will flow to the group; and

the costs incurred or to be incurred in respect of the transaction can be measured reliably.

When the outcome of a transaction involving the rendering of services can be estimated reliably, revenue associated with the transaction is recognised by reference to the stage of completion of the transaction at the end of the reporting period.

the outcome of a transaction can be estimated reliably when all the following conditions are satisfied:

the amount of revenue can be measured reliably;

it is probable that the economic benefits associated with the transaction will flow to the group;

the stage of completion of the transaction at the end of the reporting period can be measured reliably; and

the costs incurred for the transaction and the costs to complete the transaction can be measured reliably.

When the outcome of the transaction involving the rendering of services cannot be estimated reliably, revenue shall be recognised only to the extent

of the expenses recognised that are recoverable.

Service revenue is recognised by reference to the stage of completion of the transaction at the end of the reporting period.

Stage of completion is determined by the actual costs in relation to the planned cost of a project.

Service fees included in the price of the product are recognised as revenue over the period during which the service is performed.

Contract revenue comprises: the initial amount of revenue agreed in

the contract; and variations in contract work, claims and

incentive payments: - to the extent that it is probable that

they will result in revenue; and - they are capable of being reliably

measured. Revenue is measured at the fair value of

the consideration received or receivable and represents the amounts receivable for goods and services provided in the normal course of business, net of trade discounts and volume rebates, and value added tax.

Interest is recognised, in the Statement of Comprehensive Income, using the effective interest rate method.

1.18 Translation of foreign currencies

Foreign currency transactions A foreign currency transaction is

recorded, on initial recognition in Rand, by applying to the foreign currency amount the spot exchange rate between the functional currency and the foreign currency at the date of the transaction.

At the end of the reporting period: foreign currency monetary items are

translated using the closing rate; nonmonetary items that are measured

in terms of historical cost in a foreign currency are translated using the exchange rate at the date of the transaction; and

nonmonetary items that are measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined.

exchange differences arising on the settlement of monetary items or on translating monetary items at rates different from those at which they were translated on initial recognition during the period or in previous financial statements are recognised in profit or loss in the period in which they arise.

Cash flows arising from transactions in a foreign currency are recorded in Rand by applying to the foreign currency amount the exchange rate between the Rand and the foreign currency at the date of the cash flow.

Other information

Details of properties

Funding received during the current financial year for the purchase of assets is R58,463,012 (R60,366,325 for 2013).

A register containing the information required by Regulation 25(3) of the Companies Regulations, 2011 is available for inspection at the registered office of the company.

Fully depreciated assets and funded assets with a total acquisition value of R182,779,858 (2013 - R137,127,343) are still in use. these assets are recorded at R1 in the asset register.

Mintek reassessed the useful life of all zero value assets due to the fact that they are still in use and have future economic value. the useful lives were extended based on the assumptions that assets will be replaced in the next two years due to a capitalisation plan. the original acquisition value for these assets were R12,016,434 and the resultant depreciation write back was R2,748,670, of which R2,344,147 relates to property, plant and equipment and R404,523 relates to intangible assets (refer to note 19).

Fair value of trade receivables

trade and other receivables 55 005 262 45 463 717 55 005 262 45 463 717

In terms of IAS 39 outstanding customer invoices are discounted throughout the year to show the deemed interest that Mintek has forfeited. A basis rate of prime interest rate (annual weighted average) less 5% has been used due to the fact that this is a fair representation of the interest that Mintek earns through liquid deposits.

Provision for impairment

Included in the trade receivable balance are debtors which are past the original expected collection date at the reporting date, with a carrying amount of R2,494,212 (2013:R3,500,778) for which the company has not provided as there has not been a significant change in credit quality and the amounts are still considered recoverable. the company does not hold any collateral over these balances. the average age of outstanding balances is 61 days (2013: 69 days). A summarised age analysis of due debtors is set out below.

the ageing of amounts due but not impaired is as follows:

In determining the recoverability of a trade receivable, the company considers any change in the credit quality of the trade receivable from the date credit was initially granted up to the reporting date. Accordingly, the directors believe that there is no further credit provision required in excess of the provision for doubtful debts.

the maximum exposure to credit risk at the reporting date is the fair value of each class of receivable. the group does not hold any collateral as security.

27. Financial Instruments

Foreign currency risk

Foreign currency risk is the risk that the fair value or future cash flow of a financial instrument will fluctuate because of changes in foreign exchange rates. The group undertakes certain transactions denominated in foreign currencies hence exposure to exchange rate fluctuations arises. exchange rate exposures are managed by operating a uS Dollar based bank account within approved policy parameters and the group does not use derivatives to hedge its exposure.

Credit risk management

Financial assets that could subject the group to credit risk consist principally of bank balances and cash, deposits, trade and other receivables, and short-term investments. The Group bank balances and short-term investments are placed with several financial institutions with at least BBB credit ratings as rated in terms of the Fitch Global Rating system. the Group reviews its trade and other receivables at each balance sheet date to ensure adequate allowances for doubtful receivables or loan write-offs are made, the level of this provision is disclosed in note 6. Credit risk with respect to trade receivables is limited to the large number of customers comprising the Group’s customer base and their dispersion across different industries and geographical areas. Accordingly the Group does not have significant concentration of credit risk.

the Group considers its short-term investments to be secured and readily available as cash should the need arise for the conversion of the investments.

The carrying amounts of financial assets included in the balance sheet represent the Group’s exposure to credit risk in relation to these assets. The Group does not have any significant exposure to any customer or counter party.

Liquidity risk

Prudent liquidity risk management implies maintaining sufficient cash resources to meet cash flow requirements. Management monitors forecasts of liquidity reserve on the basis of expected cash flow. Analysis of the various requirements is disclosed in note 7 of the financial statements.

Fair values

As at 31 March 2014 the carrying amount of bank balances and cash, deposits, trade and other receivables, trade and other payables, contracts in progress, advances received and short-term borrowings approximated their fair values due to the short-term nature of these assets and liabilities.

The group does not hedge foreign exchange fluctuations.

Interest rate risk

the valuation of interest rate exposure and investment strategies is done on a regular basis. the risk arises from substantial interest-bearing assets at variable interest rates. To minimise exposure to this risk, the Group uses a mixture of variable and fixed interest rates.
