Designed for Value: A Proven Strategy

1. Acquire producing or near-term, cash-flowing mines at a discount to value we will create• Remedy history of underinvestment in sustaining capital that limits current performance

(e.g. underground development, stripping, maintenance)• Introduce major improvements in mining methods• Modernize plant and operating practices to increase throughput & recovery• Institute operating cost reductions and productivity improvements• Leverage commercial savvy and direct smelter relationships to improve treatment costs• Identify and develop unrecognized or underinvested exploration potential to support

expanded production and/or mine life extension2. Reinvest near-term, growing cash flow to fund turnaround plan3. Return cash to shareholders wherever possible4. Repeat5. Divest mature, optimized mines to parties who can create more value than we see

Mandalay acquires undervalued mines in accretive transactions; turns them around to crystallize increased value in the market; returns cash to shareholders

Mandalay has acquired three mines at discount and turned around all three inseven years; looking for more

Flat, virtual, low-cost organizational structure; local GM accountability

Direct relationships and sales contracts with customers

Return cash to shareholders when possible

No hedging of metal prices

Costerfield keys to turnaround:Record High Rate Record Low Cost

Improved mine output/mill throughput from 170 tpd to 450 tpd (capped by grid power and site grinding capacity)

Changed mining method from cut-and-fill to blast-hole stoping with cemented rock fill (greater production, lower unit costs)

Increased sub-level spacing from 5 to 10 m

Introduced contract capital development for faster and lower cost results

Replaced mechanized mining fleet

Introduced mobile crusher to decrease particle size of mill feed (better recoveries, higher throughput)

Grew mine life from zero reserves to roughly 4 years while mining continuously for 7 years – discovered Cuffley and N-lode

2016 Production 13,792 oz Au, 1,731,031 oz Ag

Project Status: Inundation at Delia NW mine on June 9, 2017 Production suspended pending risk assessment for restart Independent root cause investigation report ongoing Risk assessment on restart of Laguna Verde mines due Dec ‘17

No significant loss of Reserves or LOM production in long-term Restart timing depends on receipt of multiple permits required for

the LOM, some of which have been in progress for many months

“Sinter” Hill -- silicified and brecciated volcanics with abundant, coarse barite

• Possible zone of significant fluid upflow–“steam heated”

• Potential for Au mineralization below

Meseta veins– typical CB-style qtz-adularia-Ag-Au>Base Metal veins

Equus reports Ag-Base metal veins with intermediate argillic alteration some 5 km south

2. Execute focused operational improvement projects at each site

3. Apply relentless, disciplined financial management

• Maintain good Björkdal performance; further upside includes optical ore sorting, extended mine life with exploration, possibility of significant higher-grade skarn

• Extend Costerfield life with Brunswick lode development and beyond with further exploration• Restart Cerro Bayo with optimized, risk-assessed plan• Optimize Challacollo feasibility with lower capital and operating costs• Mining – projects focused on safer, more mechanized mining with higher extraction, lower dilution

and reduced cost• Metallurgical – projects focused on higher recovery, higher availability, higher quality products with

higher payables and reduced costs• Commercial – more diverse customers paying better terms

• Low cash cost and overheads for high EBITDA margins• Low DD&A for high P&L margins – low acquisition cost, focused CAPEX & exploration • Prudent, low-cost leverage to fund growth when needed• Minimize shareholder dilution• Compare all potential uses of cash to the benefits of returning cash to shareholders
