Mandalay Resources is continuing to see production growth and exploration success at its Costerfield gold-antimony mine in Australia. Costerfield has seen a significant ramp-up of high-grade Youle vein production since late 2019, with stable production scheduled over the next 4 years. Recent exploration success has also grown the mine life. Cash costs are expected to be $675-825 per ounce in 2021. Mandalay plans $16-20 million in capital expenditures at Costerfield in 2021, focusing on further exploration to test targets and generate new prospects.

2. Forward-looking Statements
This presentation contains "forward-looking statements" within the meaning of applicable securities laws, including statements relating to life of mine
production plans, exploration plans and the growth and strategy of Mandalay. Actual results and developments may differ materially from those contemplated
by these statements depending on, among other things: exploration results or production results not meeting management’s expectations; capital, production
and operating cost results not meeting current plans; and changes in commodity prices and general market and economic conditions. The factors identified
above are not intended to represent a complete list of the factors that could affect Mandalay. A description of additional risks that could result in actual results
and developments differing from those contemplated by forward looking statements in this presentation can be found under the heading “Risk Factors” in
Mandalay’s annual information form dated March 31, 2021, a copy of which is available under Mandalay’s profile at www.sedar.com. Although Mandalay has
attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements,
there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. There can be no assurance that forward-
looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly,
readers should not place undue reliance on forward-looking statements.
Quality Control and Assurance

2021 PRODUCTION GUIDANCE
Two producing gold mines in Australia and Sweden –
both mining-friendly, tier-one jurisdictions
• Successful turnaround with both operations continuing to be
significant cash generators in 2021
• At Costerfield, significant Shepherd discovery during 2021,
currently performing extension drilling
• Björkdal beginning to reap the benefits of higher grade, wider
Aurora zone
• Exploration success at Björkdal, finding higher grades at
depth to north-east
• Cerro Bayo’s overall contribution to be 9,000 – 10,000 ounces
of gold equivalent by year end

• Costerfield is the second highest grade gold mine in Australia after neighboring
Fosterville mine. Shepherd discovery continues high grade results
• Increasing gold recoveries at plant with CavTube flotation installation
Targeting high-grade mineralization at depth
• Regional success has shown potential for super grade deposits within the region
• The second hole in this program intercepted visible gold in two zones at a depth of 900m and
1,000m.
• Deep hole program recommenced in 2021 targeting under Shepherd discovery
Surface drilling on highly-prospective targets
• Shepherd and Brown’s targets returned significant results in 2021.
• Targets currently being drilled and planned include; Margaret, Brunswick Deeps, Cuffley Deeps

23. • Fosterville is the highest grade mine in the
world based on Q1 2021 production(1)
• Costerfield was the 7th highest grade mine in
the world based on Q1 2021 production and is
30 km east of Fosterville(1)
• Costerfield is mineralogically similar to
Fosterville and probably shares a source and
timing of mineralization
• The emplacement environment of Fosterville
has been located below Costerfield
• Deep drilling at Costerfield looks to unlock a
highly enriched domain within the field

29. Aurora Zone: Key to Lifting Underground Production
• Mineralization found to extend hundreds of
metres; previously was constrained by a marble
contact
• Significantly wider and consistently higher-grade
than current ore – open at depth
• Current known mineralization over 500 m
horizontally and 400 m vertically
• Readily accessible; 13 levels currently being
developed
• Stoping has been initiated on first levels
• Large step-out drilling occurring below and
East and West of currently known mineralization

Emerging growth catalyst in development

(Blue) and Björkdal shear (Yellow). Drilling of the 2021 Main Zone extension and Lake Zone infill drilling is also shown

30. Aurora Zone Exploration Success
Mineralization open in all directions
• Underground drilling campaign focused on extending
Aurora zone
• Drill results demonstrate potential to extend Aurora in all
laterally and down dip
• High-grade mineralization continuity has been confirmed
at depth and to the east in early 2021
