Portfolio strategy and scale

• Four brownfield gold projects with existing infrastructure are planned around the Lone Tree autoclave and CIL processing hub.

• Production targets are 400,000-500,000 oz annually in the five-year plan and ~600,000 oz annually by the early 2030s.

• Portfolio resources include 7.3Moz measured and indicated gold at 0.79 g/t and 7.4Moz inferred gold at 0.99 g/t; deposits remain open for expansion.

• Nevada ranked #1 globally for mining investment attractiveness in the Fraser Institute's 2025 survey, up from #2 in 2024.

Funding and Lone Tree plant

• Recapitalization completed in Q1 2026, with >$1B in secured and available capital and $165M of existing debt retired in March 2026.

• Secured and committed capital fully funds Granite Creek and Archimedes underground development and the Lone Tree plant refurbishment.

• Lone Tree's estimated project cost is $430M, including contingency and capital spares; potential payback is 12-24 months depending on grade and gold price.

• Granite Creek underground is operating and ramping up; 2025 gold production was 22,977 oz, and 2026 guidance is 30,000-40,000 oz.

• Granite Creek's September 2026 feasibility study estimates 557koz of proven and probable reserves, an ~8.5-year mine life, and 75.1koz average annual production in 2028-2032 at $1,915/oz AISC.

• Archimedes is under construction, with 436koz indicated and 988koz inferred resources; its PEA estimates 101.9koz average annual production at $1,893/oz AISC.

• Upper Archimedes first gold mined is targeted for Q4 2026; lower 426 and Ruby Deeps drilling is underway, with a feasibility study anticipated around mid-2027.
