Study shows potential value of $600 million for i-80 Gold’s Granite Creek Underground - Elko Daily Free Press

AI desk brief

i-80 Gold’s Granite Creek Underground feasibility study assigns the project a nearly $600 million NPV at current gold prices, highlighting a materially higher-value asset as the company advances redevelopment of its Nevada gold complex. The study cites initial production of about 105,000 oz from 2027-2031, with all-in sustaining costs around $1,645/oz over the five-year steady-state period and an initial mine life of roughly 6.3 years.

The project is also framed as a key feed source for the Lone Tree autoclave, with i-80 saying Granite Creek underground and Archimedes ore are expected to supply a third-party processing route in the near term before Lone Tree restarts. Management said the updated underground resource model, improved geologic continuity and added exploration targets support further expansion potential.
