Positive Impact 4 of 5 other Written later

i-80 Gold furnished a September 21, 2026 press release on a feasibility study for its Granite Creek Underground gold project in Nevada. The base case shows an after-tax NPV (5%) of $118 million at $2,750/oz gold, rising to $598 million at $4,500/oz, and the study reports initial reserves of 556,500 oz gold. The filing also furnishes Mineral Point assay results, and the company says the study's production and sustaining capital figures improved on the March 2025 preliminary economic assessment.

Key points

  • Base case at $2,750/oz gold: after-tax NPV (5%) of $118 million and undiscounted after-tax cash flow of $153 million.
  • Initial proven and probable reserves of 2.20 million tonnes grading 7.87 g/t gold, containing 556,500 oz gold; mine life of about 8.5 years.
  • Average annual gold production of about 75,000 oz from 2028 to 2032, versus the March 2025 PEA; sustaining capital of $83 million, which the company says is lower than the PEA.
  • Lone Tree Plant commissioning is planned for the fourth quarter of 2027; inferred resources fell 38% as infill drilling upgraded material to higher categories.
