i-80 Gold Extends Upper Archimedes Mineralization, Accelerates Development
Event summary
- i-80 Gold reported high-grade assay results at the Archimedes Underground Project, including 24.6 g/t Au over 23.6 meters.
- Construction of the Archimedes underground project commenced in Q3 2025, with first gold expected in Q3 2026.
- The project hosts an indicated gold mineral resource of 436,000 ounces at 7.6 g/t and an inferred resource of 988,000 ounces at 7.3 g/t.
- Development footage at Upper Archimedes has exceeded plan, with approximately 1,200 meters completed as of Q1 2026.
The big picture
i-80 Gold’s progress at Archimedes underscores the continued interest in Nevada’s gold deposits and the potential for smaller-scale, underground operations to contribute meaningfully to overall gold supply. The company’s strategy of leveraging a central processing facility and pursuing a hub-and-spoke mining model aims to improve efficiency and reduce costs, but hinges on the successful integration of multiple underground projects.
What we're watching
- Resource Expansion
- The potential for further mineralization beyond the current resource estimate at Upper Archimedes will be a key driver of future value, and the results of the ongoing drilling program will be critical to assess.
- Oxide Integration
- The economic viability of integrating the newly discovered oxide mineralization into the mine plan remains uncertain and will depend on metallurgical testwork and gold price fluctuations.
- Feasibility Study
- The upcoming feasibility study, expected in Q1 2027, will be crucial in validating the project’s economics and outlining the long-term production profile.
