Date assessed : 4/12/2020 No. samples processed : 56

Impact Scan utilises mineralogy obtained from either Hyperspectral Scans (automated core or hand held scans), X-Ray Diffraction

(XRD) or geological logging sources, in addition to strategic chemistry data to predict important geological material properties and

potential behaviour associated with resource development activities. With appropriate input data, the tool can identify the

following potential impacts and properties:

Acid & Metalliferous Drainage (AMD) / Acid Rock Drainage (ARD) / Neutral Metalliferous Drainage (NMD), Saline Drainage (SD), ANC/MPA

ratio, Excess Acid Neutralisation Capacity, Potential Leachate pH and Turbidity Potential.

Potential for Erodibility by Water, Potential Sodicity / Dispersivity in Water, Low Permeability Materials, Presence of organic matter,

Materials with Potential Milling Resistance.

Additional information on potential water quality impacts, including detailed AMD/ARD/NMD classifications and statistics, are

provided where possible. Mineral identification limitations in hyperspectral scan techniques may affect the accuracy of some Impact

Scan predictions. Recommendations for supplementary analytical procedures are provided to optimise the accuracy of predicted

potential hazards. Where potential impacts have been identified, supplementary testwork protocols are recommended to assist in

clarifying the potential risks.

Information on the Mineral Characteristics and Classification Categories can be found at the rear of this assessment, along with a

Glossary of technical terms.

The mineralogical and analytical data indicated below was provided by the CLIENT and/or third party laboratories and used for the

purposes of conducting the assessment.

The aim of Impact Scan is to predict the properties and potential behaviour of geological materials based on mineralogy identified

by hyperspectral scan, x-ray diffraction and visual techniques. Outputs generated by Impact Scan are not to be used for purposes

other than those for which they were intended.

Mineral characteristics that could contribute to potential hazards identified by Impact Scan are based only on mineralogy, and

where available, analytical sulfur and carbon data provided by the Client, or third party laboratory, and is assumed to be accurate.

All assessments provided are based on individual sample characteristics. The assessed potential of individual samples may vary

greatly from the actual potential due to a range of factors and, as a result, some samples may require supplementary testwork to

better clarify their properties or behaviour. Where appropriate, supplementary analytical procedures are suggested. It is

recommended that any supplementary testwork be discussed with a professional geochemist prior to implementation.

This output has been generated by Impact Scan 1.02 (release date 01/11/2020) using the data provided by the Client and

supersedes any previous reports(s) issued under the same work order / report number.

GLOSSARY

Fibrous minerals: Minerals with the potential to occur in an asbestiform habit (ie. particles with a diameter of less than 3 µm, length greater than 5 µ m

and an aspect ratio (length to width) greater than or equal to 3:1). The mineralogy of potentially asbestiform minerals may be identified, the crystal

shape and size is not.

Acid Neutralising Capacity (ANC) : A measure of the potential acid neutralising capacity of the sample, typically due to the presence of calcium- and/or

magnesium-bearing carbonate minerals. The calculated ANC value assumes that all of the carbonate minerals present are available for acid

neutralisation. ANC values are provided in units of kg H2SO4/tonne rock.

AMD/ARD: Acid and Metalliferous Drainage / Acid Rock Drainage generated by the oxidation of sulfide minerals (predominantly pyrite), and the

dissolution of acid storing sulfate minerals (eg. jarosite, alunite). The resultant drainage is generally low pH (<4.5) and contains elevated dissolved metals

and sulfate concentrations.

AMD/ARD Assessment Notes: Additional information on the sample assessments possibly including specific interpretation on the Total Sulfur and Total

Carbon data (if provided). A detailed explanation of the codes used in this section is provided below.

Chromium reducible sulfur (S-Cr): Laboratory analytical technique for quantifying the proportion of sulfur in the form of sulfide minerals within a

sample.

Detailed AMD/ARD Classification: The classification of a sample’s potential AMD risk, based on the NAPP calculated from mineralogical and possibly

Total Sulfur data. Detailed classification categories from highest to lowest acid generating risk are High Potential for Acid Generation; Moderate / High

Potential for Acid Generation; Moderate Potential for Acid Generation; Low Potential for Acid Generation; Unlikely to be Acid Generating; Likely to be

Acid Consuming.

Total Sulfur (Total S): The total sulfur content of a sample can be determined by laboratory analysis, or it can be calculated from the mineral chemistry.

The difference between laboratory measured total sulfur and the mineralogy calculated total sulfur can result from some mineralogical techniques not

being able to identify all sulfide minerals (eg. hyperspectral scans).

General AMD/ARD Classification: The simplified classification of a sample’s potential AMD/ARD risk, based on the NAPP calculated from mineralogical

and possibly Total Sulfur data. By convention samples are classified as either Potentially Acid Forming (PAF) (calculated NAPP > 0 kg H2SO4 / tonne) or

Non-Acid Forming (NAF) (calculated NAPP≤ 0 kg H2SO4 / tonne). It is often recommended that materials identified with the potential to generate acid

(PAF) should undergo supplementary static geochemical testwork.

Maximum Potential Acidity (MPA): A calculation of the maximum amount of sulfuric acid (H2SO4) acidity equivalent that could be produced by the

acid generating minerals (eg. some sulfides and sulfates). The amount of acid potentially produced by each mineral is controlled by the stoichiometry of

its acid generating reactions. Not all sulfide-bearing minerals have the capacity to produce acid. MPA is expressed in units of kilograms of sulfuric acid

equivalent per tonne of sample (kg H2SO4 / tonne). Discrepancies between Total Sulfur calculated from mineralogy and that provided by Total Sulfur

analyses are used to enhance the accuracy of MPA calculations.

Net Acid Generation (NAG) Suite: Net Acid Generation (NAG) tests determine the balance between acid generating and acid consuming materials

present. The tests involve the use of hydrogen peroxide to accelerate the oxidation of sulfides to produce the maximum acid generation possible within

a sample. Acid released by sulfide oxidation may be involved in simultaneous neutralisation reactions with and carbonate minerals present. As well as

acid generation by oxidation of sulfides, any acid-producing sulfate minerals may also release stored acid.

Net Acid Producing Potential (NAPP): One measure of the overall acid-generating potential of the sample, calculated by subtracting the ANC value

from MPA. NAPP values are expressed in units of kilograms of H2SO4 equivalent per tonne of sample (kg H2SO4 / tonne).

Non-Acid Forming (NAF): Samples that are classified as likely to be Non-Acid Forming based on the static geochemical parameters or calculated from

mineralogy provided (ie. NAPP ≤ 0).

Potentially Acid Forming (PAF): Samples that are classified as Potentially Acid Forming based on the static geochemical parameters or calculated from

mineralogy provided (ie. NAPP > 0).

Primary Description / Lithology: This represents the primary sample descriptor provided by the Client, generally representing various mine materials

(eg. ore, waste rock, wallrock and tailings). This term may also represent any differentiating characteristic of the rock that may be provided by the Client

(eg. prospect name, mine name, deposit name, lithology, geological formation, Flood Plain Sample…etc).

Secondary Description / Lithology: This represents the secondary sample descriptor provided by the Client, often representing the sample lithology

provided. This term may also represent any differentiating characteristic of the rock that may be provided by the Client (eg. prospect name, mine name,

deposit name, geological formation, Flood Plain Sample…etc).

Total Carbon (Total C or CTOT): The total amount of carbon in a sample can be determined by laboratory analysis, or it may be possible to calculate from

the provided mineralogical data. It is possible that there could be discrepancies between laboratory measured Total Carbon values and the mineralogy

calculated Total Carbon values.

MINERAL CHARACTERISTICS AND CLASSIFICATION CATEGORIES

Low Permeability Materials: This parameter assists with the identification and quantification of low permeability minerals. Such materials are often

useful as construction resources (eg. dams or tailings embankments). A suite of minerals with the potential to generate low permeability construction

resources has been collated. Samples containing <10 % combined fine grained materials are not reported. The remaining samples are classified as

having low, moderate, high and very high concentrations of low permeability materials when the combined content of the potentially low permeability

minerals is 10-25%, >25-50% and >50-75% and >75% respectively. It is worthwhile cross-checking the sodicity / dispersivity potential of any low

permeability materials. Supplementary analytical work is recommended for materials that are rated as comprising potentially significant low

permeability resources.

Output: Low, Moderate, High, Very High.

ANC/MPA Ratio: This parameter provides the ratio between a samples Acid Neutralising Capacity (ANC) and its Maximum Potential Acidity (MPA). This

ratio offers a good indication of the likelihood of AMD/ARD generation and additionally provides a safety factor for acid release from theoretically NAF

materials. ANC/MPA ratios of <1 are PAF (potentially acid forming) materials. ANC/MPA ratios from 1-2 represent high risk NAF (non-acid forming)

materials, values from >2-3 indicate moderate risk NAF materials, and anything with an ANC/MPA>3 is a low risk NAF material. Values in red are

calculated from mineral and excess sulfur data.

Output: Numerical values <1, 1-2, >2-3, >3.

AMD/ARD Hazard Classification: This parameter provides AMD/ARD hazard classifications that are based on mineralogy provided by the Client. Some

minerals have the potential to be acid generating and others can be acid neutralising. It should be noted that not all sulfide minerals are acid generating

and not all carbonate minerals are acid neutralising. Given these limitations, mineralogy data is used to calculate the Maximum Potential Acidity (MPA)

and Acid Neutralisation Capacity (ANC) for each sample, which permits determination of its AMD/ARD Hazard Classification (ie. Potentially Acid Forming

(PAF) or Non-Acid Forming (NAF)). Hyperspectral Scan mineralogy data may need to be supplemented with additional static geochemical data due to its

limitations in identifying all reactive sulfide minerals. Recommendations for supplementary analytical procedures are provided where appropriate.

Output: General - NAF, PAF; Detailed - High Potential for Acid Generation, Moderate/High Potential for Acid Generation, Moderate Potential for Acid

Generation, Low Potential for Acid Generation, Unlikely to be Acid Generating, Likely to be Acid Consuming.

Erodibility by Air (Dust): This parameter assesses the likely physical stability of each sample when exposed to erosion by wind. The potential for a dust

hazard from any material is proportional to its concentration of fine sand to clay particles. The Wind Erodibility classification of Hazelton and Murphy

(2007) is used as the basis for this parameter. The erodibility of the sample is classified as High if ≥90% occurs as fine sand to clay, Moderate if 70-90%

occurs as fine sand to clay and Low if 10-70% occurs as fine sand to clay. Any concentration below 10% is not reported. Common grainsize

characteristics of typical rock forming minerals (eg. clay minerals), are applied to each mineral identified. This assessment provides a good initial

indication of the potential of samples to generate dust. It should be noted that several other factors (eg. hardness, metamorphic grade, associated

mineralogy, environment, blasting) can also impact on dust generation. If dust generation on site could be an issue, supplementary testwork procedures

are recommended.

Output: Low, Moderate, High.

Erodibility by Water: This parameter assesses the likely physical stability of a sample under the action of erosion by water. The potential for erosion by

water is strongly related to the texture of a material and the bonding between particles. Water erosion is normally a parameter assigned to a highly

weathered or soil-like material. Material textures are assigned to samples based on their mineralogy. Clays with the potential to display a high ESP

(exchangeable sodium percentage – high sodicity) are included in this list, as the ESP provides a measure of particle bonding. Erodibility potential is

therefore assigned to samples based on the relative proportion of very fine grained, clay-rich materials with the potential to contain exchangeable

sodium. No reporting is conducted on samples with <10% potentially fine grained materials. A low, moderate, high and very high erosion rating is

based 10-25%, >25-50% and >50-75% and >75% combined potentially fine grained materials respectively.

Output: Low, Moderate, High, Very High

Excess ANC: Indicates an acid neutralising capacity (ANC) in excess of a samples acid generating capacity (MPA). Materials with an excess acid

neutralising capacity may be a potential resource for mitigating acid generating materials or assist in the construction of geochemically benign

engineered facilities. Units of measure for Excess ANC are in kg CaCO3 eq. / tonne rock. Values in excess of 100 would normally indicate potentially

significant neutralising materials.

Output: Numerical value with units of kg CaCO3 eq. / tonne rock.

Minerals with Potential Fibrous Habit: This parameter provides a preliminary high-level assessment of the presence of minerals that could theoretically

exhibit an asbestiform habit. The WHO (1999) has identified up to 10 minerals as having the potential to be asbestiform and regards a mineral as

asbestiform if the diameter of individual crystals is <3 µm, the length >5 µm and the aspect ratio is ≥ 3 to 1. Mineralogy data alone cannot assess the

physical properties of these minerals. Additional supplementary testwork procedures such as optical or electron microscopy are recommended if one or

more of the potential asbestiform minerals is identified. It should be noted that hyperspectral scan mineralogy cannot identify all potentially

asbestiform minerals, meaning that their absence from such data is not an indication that no potentially fibrous minerals are present.

Output: Possible


Example

Maximum Potential CO2 Emissions: This parameter reports on the maximum potential carbon dioxide (CO2) emissions that could be released from each

sample. CO2 gas can be released from carbonate minerals in the presence of acid generating minerals (ie. reactive sulfides and acid-sulfates). This

parameter is recorded in units of kg CO2/tonne of rock. The magnitude of potential CO2 emissions is limited by either the concentration of acid

generating or acid neutralising carbonate minerals, whichever is stoichiometrically the smallest. Values < 0.1 kg CO2/tonne not reported.

Output: Numerical value with units of kg CO2/tonne of rock.

Milling Resistance: This parameter reports on the relative resistance likely to be encountered during the milling of each sample based on mineral

hardness alone. The resistance factor varies from 1 to 5 (minimum to maximum resistance) based on the combined silica mineral content of each sample.

Note that while a milling resistance factor is applied to all samples, it is only relevant to samples classified as ore. A grainsize assessment of materials is

normally also considered for ore materials when assessing milling resistance, and this is not included in this preliminary assessment. Supplementary

analytical work is recommended for materials identified with potential milling resistance factors.

Output: Numerical value between 1 and 3, 1 = 30-50%, 2 = 50-70%, 3 > 70%.

Neutral Metalliferous Drainage (NMD) Potential: This parameter estimates the initial potential of a sample to generate near-neutral but metalliferous

drainage. Acid released from reactive minerals has the potential to react with neutralising phases such as carbonates to generate near neutral water.

However, some metals and metalloids mobilised into solution under acid conditions remain in solution at neutral pH values. This type of drainage is

referred to as Neutral Metalliferous Drainage or NMD. Typical NMD components in water can include Zn, As, Sb, Se, Mn, Cr and Mo. Samples with a

Maximum Potential Acidity (MPA) values >10 kg H2SO4/tonne and a negative NAPP (ANC>MPA) are considered to have the potential to generate NMD.

Additional supplementary analytical procedures are recommended to confirm the formation and assess the composition of NMD.

Output: Possible

NORM (Naturally Occurring Radioactive Minerals): This parameter records the presence of NORMs within each sample. Mineralogical data is cross

referenced with a list of eight (8) common radioactive minerals. The number of NORMs is listed for each sample. It is important to note that

hyperspectral scan data cannot identify many of the NORMs. Therefore, the absence of one or more radioactive mineral signatures in any hyperspectral

dataset may not mean that they are not present in the sample.

Output: Numerical value listing the number of NORMs identified.

Organic Matter: This parameter identifies the presence and indicative abundance of organic matter in each sample. Organic matter is generally

amorphous and is only directly recognised using hyperspectral scan methods, rather than conventional XRD techniques. The types of organic matter

that are likely to be recognised using hyperspectral scanning include recent surficial biomass, ligneous material, bituminous carbon and other near

graphitic or graphitic materials. Values <1 % are not highlighted, but values from 1-10%, >10-30% and >30% are reported as Low Moderate and High

respectively.


Likely Drainage pH: This parameter provides an initial indication of the likely pH of drainage (leachate) from each sample following their extended

exposure to air and water. There are two categories of leachate indicated: (i) pH <4.5 (acid) and (ii) pH ≥4.5 (non acid).

Output: Numerical values <4.5, ≥4.5

Salinity: This parameter estimates the potential for sulfate, bicarbonate and chloride salinity release from each sample. The ability to accurately quantify

the potential release from each salinity type relies on the accurate and comprehensive reporting of all potentially saline mineral phases. It should be

noted that hyperspectral scan mineralogy cannot identify all potentially saline mineral phases. Sulfate salinity can be released from reactive sulfides and

soluble sulfate minerals. Bicarbonate salinity can be released from carbonate minerals in the presence of acid generating minerals. Chloride salinity can

be released from soluble chloride mineral phases which can be identified by conventional XRD analysis. The salinity potential is classified as Low,

Moderate or High, based on sulfate equivalent salinity units corresponding to 1-5 wt.% S, 5-10 wt.% S and >10 wt.% S. Additional oxygen consumption

testwork may be useful for samples displaying elevated sulfate and/or bicarbonate salinity. Other leach testwork may be more appropriate for chloride

salinity.


Sodicity / Dispersivity: This parameter identifies the presence and records the relative abundance of minerals with the potential to exchange sodium

when exposed to water. This cation exchange capacity can be responsible for the swelling or shrinkage (molar volume change) of specific minerals,

which can sometimes enhance their ability to automatically disperse (disaggregate) when exposed to water, promoting various forms of erosion (eg.

tunnelling and channelling). A strategic short list of potentially dispersive minerals has been compiled. Additional supplementary testwork procedures

are recommended if these properties may be problematic for re-use or disposal of these materials. The potential for a sample to display dispersive

behaviour is rated as Low, Moderate, High and Very High, based on the combined content of potentially dispersive clays from, 10-25%, >25-50% and >50-

75% and >75% respectively.

Output: Low, Moderate, High, Very High

Turbidity: Turbidity provides a measure of the quantity of suspended solids in water resulting from erosion. It is a measure of the cloudiness, or loss of

clarity in water. This parameter is closely related to the “Erodibility by Water” parameter, as well as the potential for “Sodicity / Dispersivity” in a sample.

The potential for materials to impact on the turbidity of surface water is proportional to the concentration of fine silt and clay particles. A list of minerals

with the potential to exhibit an ultra-fine grained habit has been compiled. The potential to generate turbid water is rated as Low, Moderate, High and

Very High based on the proportion of combined clay-sized minerals at 10-25%, >25-50% and >50-75% and >75% respectively.

Output: Low, Moderate, High, Very High.
