BJÖRKDAL OPERATIONS

An attractive asset with continued optimization potential

ASSET OVERVIEW – Similar challenges to those faced by Mandalay at Cerro Bayo and Costerfield A narrow vein, nuggety ore body that is highly levered to grade control Understanding gold deportment and executing proper sampling and mapping key to success Strengthened geology/mining team to ensure proper planning and execution Focus on reducing dilution from both underground and open-pit mines Open Pit

Grade control drilling in pit and employment of experienced pit geologists New pit contractor at lower rate with new equipment

Underground

Successful transition to owner-operated equipment (in Q3-2013 with full transition in Q4-2013) which reduced dilution and allows for better mine planning and also reduced mining costs

Increasing ore feed to mill from underground as overall composition of 3,700 tpd mill feed New “grade control” drill in operation providing better data for stope design and layout

Mill Metallurgical characteristics allow 88-90% recovery through gravity concentration Environmentally benign - no cyanide Simple, expandable mill employing gravity concentration with no leach tanks and no reagents Low sustaining capex Long life asset having produced over 1 million ounces of gold since start-up in 1988 and having M&I resource of 1.0Moz as at March 2013

2014 GUIDANCE Expected production between 44,000-49,000 ozs at cash costs of $886-982/oz and AISC of $1,106-1,227/oz Continue focus on developing and mining higher grade underground zones Maintain ongoing grade control focus in open pit to sustain grade at ±1 g/t

GROWTH PROJECTS

Upon completion of the transaction, Mandalay will continue developing several immediate growth prospects

Cerro Bayo (Expansion) Follow-up of recent exploration success on extensions of veins currently in reserves. Expansion of mine capacity through enhanced access with 5 of 12 veins with booked reserves currently accessed for mining Expansion of mill throughput from 1,200 tpd to 1,400 tpd achieved in Q2-2014

Process facility rated at 1,650 tpd, leaving room for further increase depending on exploration success Costerfield Cuffley lode now in production, supplying high grade feed for Costerfield mill

Increase in head grade as proportion of Cuffley feed grows, will raise production rate Four year mine life Extension and infill drilling targeting further extension of mine life in 2014 Increase in sublevel spacing lowering cost

Challacollo (Feasibility) Indicated resources of 8.0Moz Ag, 13.4koz Au, inferred resources of 24.3Moz Ag, 40.1koz Au(1)

Feasibility study underway – expected Q4-2014 Björkdal (Expansion) Alternative production growth strategies

More selective mining to raise head grades at current mine tonnage production rates Ore sorting to increase head grades at current processing rates Mill expansion

Capital costs are projected to be low given the simple mill flow sheet encompassing only crush/grind, gravity, and flotation concentration

Mine capital required is also low given ramp access with no shaft

OPERATIONAL IMPROVEMENTS AT CERRO BAYO

1. Restart from care and maintenance with localized management team– all residential, no fly-in fly-out

2. Changed from historic shrinkage stoping to fully mechanized open blast hole stoping mining method– similar production with half the people and much safer

3. Focused only on the large, higher grade veins– determined to operate mill at below capacity with only the most profitable mill feed.

4. Doubled reserves on existing veins in first year– first development revealed overly conservative manually interpreted ore shells from previous owner

5. Continued exploration has extended the reserves along existing veins by another 50% with another major increment discovered in late 2013 which will partly enter reserves in 2014.

6. Installed flotation automation system on plant to improve recoveries 7. Increased customer base from one at the restart to four at present, with improved

terms

OPERATIONAL IMPROVEMENTS AT COSTERFIELD

1. Restart from care and maintenance 2. Brought modern planning standards to bear– in year 1, completed first ever

NI 43-101 compliant resource and reserve Technical Report 3. Brought into compliance with noise, dust, water management standards and upgraded

operating permits 4. Shifted to local workforce, training people who wanted to live in the community to become

miners, rather than compete for FIFO miners. 5. Improved relations and commercial terms with Chinese smelter 6. Shift from cut and fill to long hole stoping with cemented rock backfill 7. Replace aged underground mining fleet 8. Discovered and developed two new orebodies– N-lode (deep), and now Cuffley, both with

higher gold grades than historic mining 9. Focused on improving flotation recoveries by abandoning ineffective leach plant and

temporarily suspending gravity gold production 10. Over time, replaced/resized all pumps and motors in the plant to provide excellent

availabilities, narrower operating variabilities, and improved recoveries 11. Introduced fine ore crushing (low-cost mobile crusher) to maintain fine grind size to flotation

at 2-3X previous throughput– 5000 tpm nameplate rising to 12,000 tpm. 12. Commissioned new, automated gravity gold room to reintroduce producing gravity gold

product at high rate with better commercial terms
