3 A FUTURE OF GROWTH

Dominant positions in two highly prospective greenstone belts

Position of Strength

• Favourable mining jurisdiction of Western Australia
• Large under-explored greenstone belts
• Long-term operational optionality with 3 mills at Duketon and belt dominance at Tropicana with the only gold mill within 100's of kilometres

Exploration Strategy

• Grow existing mineral resources to extend mine life from both open pits and underground
• Grow mines into multi-million ounce systems
• Discovering new +1 million ounce deposits

KEY ELEMENTS OF VALUE GROWTH

Exploration Life Extension Growth

McPhillamys Step Change Growth

Grow Open Pits & Undergrounds New mines and extensions to existing mines

5 DUKETON EXPLORATION

Five Key Project Updates

Duketon North Operation (DNO) Projects

Buckingham-Wallace (Moolart Well)

Commonwealth

Duketon South Operation (DSO) Projects

• Garden Well Main Underground
• Rosemont South Underground

Ben Hur

6 DUKETON NORTH OPERATIONS

Mill Significant advances at two key projects around DNO

Buckingham-Wellington (Moolart Well)

Most significant fresh-rock mineralisation ever from Moolart reflecting limited historic work

High-grade intersections suggest excellent potential to define high-grade shoots beneath the extensive oxide mineralisation

Better results include:

• 10m @ 13.2 g/t gold from 107 m
• 26m @ 7.6 g/t gold from 128 m
• 19m @ 5.7g/t gold from 183 m (fresh rock)

Follow-up drilling has been planned to test the extensions

7 DUKETON NORTH OPERATIONS

Significant advances at two key projects around DNO

Commonwealth Prospect

An extensive 2km by 2km area of supergene gold mineralisation under definition drilling

Better results include:

• 16m @ 7.6 g/t gold
• 8m @ 3.1 g/t gold
• 8m @ 2.6 g/t gold

Future exploration will focus on infill drilling and targeting a number of deeper holes where mineralisation is interpreted to extend into the bedrock

Moolart Well Mill

15km

8 DUKETON SOUTH OPERATIONS

Significant advances to multiple projects around DSO

Garden Well Main UG Rosemont Mill

Further strong mineralisation from drilling beneath Garden Well Main pit continues to demonstrate the potential for establishing a new underground resource and potentially an additional underground production area

High-grade south plunging shoots beneath main pit taking shape

Better results include:

• 9.6m @ 4.4 g/t gold
• 9.6m @ 3.7 g/t gold
• 10.8m @ 2.3 g/t gold
• 7.1m @ 2.9 g/t gold
• 24.5m @ 3.2 g/t gold
• 8.9m @ 3.2 g/t gold

The potential for an exploration decline will continue to be investigated as further drilling is completed and confidence grows over the next 3-6 months

9 DUKETON SOUTH OPERATIONS

Significant advances to multiple projects around DSO

Rosemont South UG

High-grade gold mineralisation outside the current underground resource areas demonstrates potential for resource growth

Narrow, very high-grade intervals with free gold defined.

Better results include:

• 1.3m @ 20.4 g/t gold
• 3.9m @ 28.6 g/t gold
• 1.6m @ 23.6 g/t gold
• 1.0m @ 30.6 g/t gold
• 1.0m @ 28.2 g/t gold
• 0.3m @ 42.6 g/t gold
• 1.4m @ 11.9 g/t gold

10 DUKETON SOUTH OPERATIONS (DSO)

Significant advances to multiple projects around DSO

Ben Hur Project

Thick, high-grade extensions down dip are expected to grow the open pit resources. Deeper intercepts show early indications of potential UG lodes

Better results include:

• 18m @ 1.4 g/t gold
• 7m @ 5.4 g/t gold
• 9m @ 4.9 g/t gold
• 19m @ 3.7 g/t gold
• 14m @ 2.6 g/t gold
• 25m @ 1.4 g/t gold
• 16m @ 2.0 g/t gold
• 25m @ 1.3 g/t gold
• 23m @ 1.3 g/t gold
• 31m @ 1.6 g/t gold
• 16m @ 1.9 g/t gold
• 18m @ 5.2 g/t gold

12 TROPICANA – UNDERGROUND GROWTH

Boston Shaker UG

Strong results continue to demonstrate downplunge growth potential up to 200m below the current resource envelope and improve confidence in areas of inferred resource

Tropicana UG

Part of the production schedule with mine development allowing extension drilling from underground which is increasing confidence in the orebody

Six holes planned and underway to test the down-dip extensions to the mineralisation

13 TROPICANA – UNDERGROUND GROWTH

Havana Underground

Strong results continue from infill drilling to convert inferred resource to indicated in preparation for the 2022 Havana UG PFS

Havana South Underground

Four holes designed to test the down dip extension of high-grade ore shoots at Havana South, increase confidence in the potential for future underground extensions
