i-80 Gold Provides a Development Update; Archimedes Underground and Lone Tree Plant Refurbishment Remain on Track and Mineral Point Open Pit Prioritized in Updated Development Plan
i-80 Gold reported that its Nevada development plan remains on track, with Archimedes underground set to begin production mining in Q4 2026 and the Lone Tree Plant refurbishment advancing on schedule toward first gold pour in Q4 2027. Capital discipline is holding: the $430 million Lone Tree cost estimate remains largely intact with roughly 10% of contingency drawn, though labor costs are running 5-10% above initial estimates, and the company is prioritizing the Mineral Point open pit — its most valuable asset, with potential to add approximately 280,000 gold equivalent ounces annually over a 17-year mine life — ahead of the Granite Creek open pit.
