i-80 Gold Corp. announced positive results from a Feasibility Study (FS) for its Granite Creek underground gold project in Nevada. The study outlines an after-tax Net Present Value (NPV) of $118 million at a base case gold price of $2,750 per ounce, establishing initial mineral reserves and a clear production plan for the asset.
Key Details
- Project Economics: The study projects an after-tax NPV (5% discount) of $118 million and total after-tax cash flow of $153 million, based on a gold price of $2,750/oz. At a higher gold price of $4,500/oz, the NPV increases to $598 million.
- Mineral Reserves & Production: The FS establishes initial Proven and Probable Mineral Reserves of 556,500 ounces of gold at an average grade of 7.87 g/t. The project has an estimated mine life of 8.5 years, with average annual gold production projected to be approximately 75,000 ounces during the steady-state period of 2028-2032.
- Costs & Timeline: Life of Mine (LOM) All-in Sustaining Costs (AISC) are estimated at $2,273/oz. The company plans to process ore through third parties until mid-2027, followed by stockpiling before commissioning its wholly-owned Lone Tree processing plant in Q4 2027 to lower future processing costs.
