i-80 Gold reports high-grade drill results at Nevada’s Archimedes project

The campaign, which spanned 40 drill holes and approximately 8,500 meters, targeted the upper 426 zone to improve resource confidence ahead of mining. Beyond the high-grade sulfide mineralization, the drilling identified significant oxide intervals not previously included in the project’s preliminary economic assessment. These findings offer a potential low-cost processing path, as the company explores using its existing heap leach pad at the Ruby Hill property alongside the planned Lone Tree Plant refurbishment.

While development at the Archimedes site continues according to plan, the company is adjusting its broader technical schedule. Feasibility-level studies for the Granite Creek and Cove underground projects have been pushed from the second quarter to the third quarter of 2026. Meanwhile, a new 55,000-meter drill program is already underway, focusing on the lower 426 zone and the Ruby Deeps zone to support an updated feasibility study expected in early 2027.
