i-80 Gold Corp. announced the results of a Preliminary Economic Assessment (PEA) for its Archimedes Underground Project, located within the Ruby Hill Complex in northeastern Nevada. The PEA demonstrates an after-tax Net Present Value (NPV) of $127 million at a 5% discount rate, based on a gold price of US$2,175 per ounce.

The study also highlights an after-tax Internal Rate of Return (IRR) of 23% at the same gold price, confirming the economic viability of the Archimedes Project. These results underscore the project's potential to become a key component of the company's regional hub-and-spoke mining and processing strategy.

The Archimedes Project is expected to contribute significantly to i-80 Gold's goal of becoming a mid-tier gold producer. This positive assessment provides crucial technical and economic validation as the company continues to advance its high-grade gold deposits.
