i-80 Gold (IAU) Corporate presentation summary

Strategy and portfolio

• Four brownfield gold projects with existing infrastructure are being developed around a Lone Tree autoclave hub, with three underground mines planned as feed sources.

• The five-year plan targets annual production of 400,000–500,000 oz; the broader development plan targets ~600,000 oz/year.

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

• More than $1B in secured and available capital has been raised since early 2025 to support development and growth plans.

Granite Creek

• Underground mine is operating in ramp-up, with 557koz of proven and probable reserves at 7.87 g/t Au and an estimated mine life of ~8.5 years.

• Feasibility study estimates average annual production of ~75koz at $1,915/oz AISC during 2028–2032 after Lone Tree commissioning; 2026 production guidance is 30,000–40,000 oz.

• WTP2 was treating ~1,500–1,800 gpm, up 68% since the start of 2026; optimization targets ~3,500 gpm continuously by mid-Q4 2026.

• Open-pit resource is 1.6Moz measured and indicated at 0.97 g/t and 100koz inferred at 0.81 g/t; technical studies and permitting are underway.

Ruby Hill projects

• Archimedes underground is under construction; first ore mining and first gold from upper Archimedes are targeted for Q4 2026.

• Archimedes’ 2025 PEA estimates ~100koz average annual production after ramp-up, a ~10-year mine life and $127M after-tax NPV at a $2,175/oz gold price.

• Mineral Point’s 2025 PEA outlines a ~17-year mine life and ~280koz annual gold-equivalent production; after-tax NPV is $614M at $2,175/oz gold and $27.25/oz silver.

• Mineral Point’s 2026 drilling program plans ~130,000 m in 312 holes; initial step-outs indicate potential to extend mineralization ~1 km along strike and 300 m in width.
