Portfolio and strategy

• Three Great Basin assets: producing Florida Canyon in Nevada, DeLamar in Idaho and Nevada North in Nevada; stated resource inventory of 7.7Moz AuEq M&I and 4.3Moz inferred, using $3,000/oz Au and $35/oz Ag.

• Strategy combines Florida Canyon cash flow with DeLamar and Nevada North development; long-term target is a 250–300koz AuEq multi-asset platform.

• Cash balance was US$111M at June 30, 2026; basic shares outstanding were 202.9M and fully diluted shares outstanding 216.7M.

Florida Canyon operations and outlook

• 2026 production guidance is 70–75koz Au; updated mine plan targets 82koz average annual production over an 8-year mine life through 2033, plus 2 years of residual leaching.

• Updated plan estimates after-tax NPV5% of $723M at current price assumptions, $0.8B life-of-mine after-tax free cash flow and mine-site AISC of $2,331/oz.

• Reserves increased 74%, mine life extended by 3 years and annual gold production increased 17% versus the prior plan; acquisition cost in 2024 was $68M.

• A 50,000m 2026 drill program allocates 42,500m to Florida Canyon, 5,500m to DeLamar and 2,500m to Nevada North.

• Near-mine drilling targets oxide material in historic dumps, gaps between pits and pit extensions; preliminary North and South dump targets total 34–56Mt at 0.11–0.25g/t Au and remain conceptual.

DeLamar development

• 2025 feasibility study outlines a 10-year heap-leach operation averaging 106koz AuEq annually, with years 1–5 averaging 119koz; current-price case estimates after-tax NPV5% of $1.9B and 97% IRR.

• The feasibility study estimates $389M initial capital, 1.0-year current-case payback, 1.8-year base-case payback and $1,480/oz AuEq life-of-mine AISC.

• NEPA began with publication of the Notice of Intent on May 29, 2026; the Record of Decision is expected in H2 2027.

• Early works, procurement, land acquisition and engineering are underway; a February 2026 US$61M bought deal supports project readiness and pre-production activities.

• DeLamar was selected for the FAST-41 transparency program in January 2026 and has a relationship agreement with the Shoshone-Paiute Tribe.
