i-80 Gold Announces Feasibility Study and Initial Mineral Assays

What Happened
i-80 Gold Corp. filed a Form 8-K on September 22, 2026, disclosing two press releases. On September 21, 2026, the company announced a positive feasibility study and an initial mineral reserve for the Granite Creek underground project, reporting an after-tax NPV(5%) of $118 million at $2,750/oz Au that increases to $598 million at $4,500/oz Au. On September 22, 2026, i-80 issued results from the Mineral Point open-pit project, including a step-out drill hole that returned 1.33 g/t Au and 39.2 g/t Ag over 225.6 meters. The press releases are attached to the 8-K as Exhibits 99.1 and 99.2.

Key Details

• Feasibility study: Positive outcome for Granite Creek underground and an initial mineral reserve reported.
• Project economics: After-tax NPV(5%) = $118M at $2,750/oz Au; $598M at $4,500/oz Au.
• Mineral Point assay: Step-out hole returned 1.33 g/t Au and 39.2 g/t Ag over 225.6 meters.
• Filings/dates: Press releases dated Sept 21 (Granite Creek) and Sept 22 (Mineral Point), 2026; included as Exhibits 99.1 and 99.2 to the 8-K.

Why It Matters
A positive feasibility study with an initial reserve provides a more concrete estimate of Granite Creek’s economic potential and is a key milestone toward project development, permitting and financing. The NPV figures show sensitivity to gold price and suggest material potential value at higher gold prices. The Mineral Point step-out assay indicates continued exploration potential at that open-pit target. Investors should view these as technical and commercial milestones; next items to watch include detailed technical reports, permitting updates, production plans, and financing actions.
