Warriedar Resources (WA8) Investor Presentation summary

Strategic focus and resource base

• Advancing gold and antimony resources in Western Australia, with a focus on the Murchison region and a belt-scale opportunity along a 70km mineralised shear.

• Holds 1.38 Moz gold and 60kt antimony for a total of 2.3 Moz AuEq, with resources open at shallow depth and along strike.

• Ricciardo deposit is the largest gold and antimony deposit within the portfolio, with a recent MRE update to 1.96 Moz AuEq.

• Aggressive drilling and exploration pipeline in 2025 targeting further growth in gold and antimony resources.

• All resources are on granted mining leases, supported by existing infrastructure including an 800ktpa CIL plant.

Ricciardo deposit and antimony resource

• Maiden antimony MRE at Ricciardo: 12.2Mt @ 0.5% Sb for 60.3kt contained Sb, making it the largest open-pit antimony resource in Australia on a granted mining lease.

• Open-pit MRE: 11.4Mt @ 3.3g/t AuEq, containing 56.8kt Sb and 331koz Au, with 37% Sb resource in M&I categories.

• High-grade gold and antimony remain open at depth, with significant drill intercepts and immediate high-grade growth targets.

• Initial metallurgical results show concentrate grade of 49% Sb with 81% recovery and up to 96% gold recovery via flotation.

• Dedicated antimony drilling is underway to define high-grade zones and update the MRE.

Growth strategy and exploration upside

• Three-pronged growth strategy: rapid advancement of Ricciardo, expansion along the 25km Golden Corridor, and greenfield discoveries along the 70km shear.

• Six discrete mineral resources along the Golden Corridor total 2.22 Moz AuEq, with 18 historic open pits and substantial exploration upside.

• Ongoing and planned drilling at Windinne Well, M1, Azure Coast, and Bugeye, targeting both brownfields and greenfields resource growth.

• 20,000m aircore program planned for Q3–Q4 2025 to test underexplored sections of the main shear.

• Rigorous geology review and ongoing target pipeline generation, with multiple rigs active on site.
