i-80 Gold Unveils Promising High-Grade Assays at Archimedes Underground Project
In a significant development for the mining sector, i-80 Gold Corp. has reported notable assay results from their Archimedes Underground Project, located in the Ruby Hill property in northeastern Nevada. The company, which is listed on both the TSX and NYSE American, shared that recent drilling has revealed impressive high-grade assays, notably 24.6 g/t of gold over a length of 23.6 meters in one of the drill holes. This extraordinary outcome is anticipated to bolster confidence in the mineral resource's continuity and extend its boundaries beyond previous estimates.
The Archimedes Underground Project is essential to i-80 Gold's three-phase development plan aimed at establishing the company as a solid mid-tier gold producer. Construction on this project began in the third quarter of 2025 and is progressing well, with initial production expected to start by late 2027 at the Lone Tree processing facility. Until then, processing of materials sourced from Archimedes will be handled through a third-party toll milling agreement.
As of December 31, 2025, the project hosts an indicated gold mineral resource estimated at 436,000 ounces, alongside an inferred resource of approximately 988,000 ounces, indicating strong potential for future extraction. The majority of these gold resources are located in the Ruby Deeps zone below the 5100-foot elevation, highlighting a solid foundation for ongoing development.
The drilling campaign at Archimedes has demonstrated consistency in high-grade mineralization, echoing previous outcomes from drilling at related projects. Tyler Hill, the company's Vice President of Geology, stated, "Drilling continues to return consistent and positive results that are improving our confidence in both the scale and the continuity of mineralization at Archimedes."
Several notable infill drilling results have emerged from the Upper Archimedes zone, including:
These promising assays have not only confirmed the upper zones’ potential but also hint at significant extensions beyond the previously defined mineral resource estimates supporting the project's economic assessments.
The current drilling program is on track to cover around 7,500 meters across 35 holes, with the complete drill campaign consisting of 36 holes expected to wrap up by the second quarter of 2026. The results aim to support further feasibility studies, with the updated mineral resource estimates anticipated early next year. Additionally, the exploration in Lower Archimedes, which remains open for substantial further resource potential, is slated to commence once the Upper Archimedes drilling wraps up.
The company is also investigating the possibility of integrating emerging oxide materials into the project to enhance the overall mine plan profitability. As the market conditions become favorable, these assorted impactful plans highlight i-80 Gold's strategic approach amid a continually evolving landscape.
In summary, the recent assay results from the Archimedes Underground Project remarkably position i-80 Gold for promising advancements within its mining ventures. The overall project remains on schedule, with expectations for initial gold extraction mid-year, solidifying its standing in the competitive Nevada mining sector. With a focus on both high-grade sulfide and potential oxide opportunities, i-80 Gold looks poised for significant growth as it targets a steady output moving forward, adhering to tight project timelines and budgetary constraints.

Several notable infill drilling results have emerged from the Upper Archimedes zone, including:
- - 24.6 g/t Au over 23.6 m from hole iAU26-05.
- - 10.2 g/t Au over 36.4 m from hole iAU25-09.
- - 8.0 g/t Au over 46.4 m from hole iAU26-01.
- - 6.1 g/t Au over 42.1 m from hole iAU25-14.
- - 3.9 g/t Au over 44.3 m from hole iAU26-03.
These promising assays have not only confirmed the upper zones’ potential but also hint at significant extensions beyond the previously defined mineral resource estimates supporting the project's economic assessments.
