i-80 Gold Corp. Unveils Noteworthy Assay Results and Project Updates

Introduction
On June 25, 2026, i-80 Gold Corp. (NYSE: IAUX) announced the remaining assay results from its recent drilling campaign at the Archimedes Underground Project located on the Ruby Hill property in northeastern Nevada. As the company prepares for production, the latest high-grade findings underscore the promising mineralization at the site, with further studies and mining operations slated for 2026-2027.

Impressive Drill Results
The assay results reveal several notable findings from the upper 426 zone, including:

• - 16.2 g/t Au over 56.4 m in hole iAU26-09 (sulfide)
• - 21.9 g/t Au over 20.2 m in hole iAU26-11 (sulfide)
• - 11.0 g/t Au over 26.1 m in hole iAU26-13 (sulfide)
• - 5.4 g/t Au over 56.5 m in hole iAU26-17 (oxide)

Paul Chawrun, the Executive Vice President and COO, expressed excitement over these results, emphasizing the expansion of the mineralized area and the continuity of high-grade materials. This information is crucial for the planning of mining operations as the company seeks to define the future development strategies for Archimedes and the Granite Creek underground sites.

Future Plans and Timelines
As i-80 Gold continues to refine its development plan, the timing for feasibility-level studies of the Granite Creek and Cove underground projects has been extended to the third quarter of 2026. The company’s renovation of the Lone Tree Plant is progressing well, aimed at positioning it to process both sulfide and oxide material efficiently, further enhancing the economic viability of the Archimedes Project.

Current Development Status
Archimedes is on track to become the company's second underground mine, with operations set to begin in late 2027. The drilling program of 2025-2026 saw 8,500 meters drilled across 40 holes. The results confirm not only the high-grade nature of materials but also reveal potential expansions beyond current estimates. Currently, the Archimedes site hosts an Indicated Mineral Resource of 1.8 million tonnes, equivalent to 436,000 ounces of gold, underscoring its significant contribution to the company's resources.

2026 Drilling Initiatives
Looking at the coming years, an additional infill drilling program targeting the lower 426 zone and Ruby Deeps zone commenced in Q2 2026, planning to complete around 55,000 meters across 140 drill holes. The outcomes from this drilling will play a pivotal role in the anticipated feasibility study for the Archimedes Project, slated for late Q1 2027. This subsequent phase aims at better defining the mineral resource, especially focusing on the oxide-sulfide transition boundary.

Conclusion
With substantial high-grade gold results and a well-defined development strategy, i-80 Gold Corp's Archimedes Project stands out in Nevada’s productive mining landscape. As the company advances towards its scheduled projections for gold mining, it positions itself for significant growth in the coming years. Keeping stakeholders informed, i-80 Gold is set to deliver promising updates and detailed technical studies by the third quarter of 2026, showcasing its commitment to sustainable and profitable mining operations.
