- Received construction permits for the Archimedes project
- Initiated underground development at Archimedes (portals, haulage decline, ventilation, exploration bays)
- Released initial assay results from Granite Creek Underground and provided infill drilling updates at Cove
- Advanced permitting and technical work on five projects following Q1 2025 assessments
- Development contract with SMD is stated to be consistent with cost estimates in the Ruby Hull PEA
- No financial details disclosed (capital costs, contract value, or financing sources not provided)
- Forward‑looking statements and references to 10‑K risk factors highlight ongoing regulatory and execution risks
Insights
TL;DR: Permits received and underground development started at Archimedes; assay and infill updates provided for other high‑grade targets.
The receipt of construction permits and the start of underground development are clear execution milestones for Archimedes and support the timeline referenced (mid‑2027) for major underground works including portals and haulage decline. The company also disclosed initial assay results from Granite Creek Underground and infill drilling at Cove, indicating ongoing exploration and resource definition efforts. The statement that the SMD development contract is consistent with the Ruby Hull PEA cost estimates suggests alignment between contractual terms and prior economic planning, though the filing does not disclose contract value or detailed schedule milestones. Reference to the 10‑K risk factors and forward‑looking disclaimers is standard and highlights regulatory and operational risks remain.
TL;DR: Multiple project updates and permit receipt are positive operational indicators, but no new financial metrics were disclosed.
The filing conveys progress on permitting and development and confirms continued exploration activity across five projects initiated in Q1 2025. These operational developments can de‑risk project delivery if executed, yet the report contains no revenue, capital expenditure, or financing details to assess funding or near‑term cash impact. Investors are pointed to the company’s 10‑K for risk disclosures; the filing reiterates standard forward‑looking statement limitations. Overall, the update is operationally constructive but lacks financial specifics in this filing.

Item 7.01 Regulation FD Disclosure
On September 5, 2025, i-80 Gold Corp. (the “Company”) issued a press release titled “i-80 Gold Receives Construction Permits and Initiates Underground Development at Archimedes.” The Company also issued a press release on September 10, 2025, titled “i-80 Gold Reports Initial Assay Results from Granite Creek Underground and Provides Infill Drilling Update at High-Grade Cove Project.” Copies of the press releases are attached hereto as Exhibit 99.1 and Exhibit 99.2 to this Current Report on Form 8-K and are incorporated herein by reference.
The information contained in this Item 7.01 and Exhibit 99.1 and Exhibit 99.2 attached hereto is being furnished and shall not be deemed filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liability of that section, and shall not be incorporated by reference into any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
Item 8.01 Other Events
The Company recently provided an update on its new development plan, which outlines a path for advancing the Company’s Nevada gold projects and creating a mid-tier gold producer. As part of the new development plan, the Company released initial assessments in the first quarter of 2025 for five projects, and continues to advance permitting, technical, and development work on these projects.
The Company recently received all of the required permits and commenced construction at the Archimedes project (“Archimedes” or the “Project”) in connection with Phase One of its development plan.
The environmental permits secured from both the Nevada Division of Environmental Protection and the Bureau of Land Management allow the Company to proceed with underground mining activities. Located on the Ruby Hill property (the “Property”) in Nevada, U.S., Archimedes is the Company’s second planned underground mine and lies approximately 180 kilometers from the Company’s wholly owned Lone Tree autoclave and carbon-in-leach (“CIL”) processing facility (see Figure 1 below). Archimedes is expected to begin contributing to gold output in the fourth quarter of 2026 (see Figure 2 below).
The Company’s three-phase development plan is expected to increase gold output to an annual target of 600,000 ounces in the early 2030s(1). Phase One of the development plan includes the ramp up of Granite Creek underground, construction of Archimedes, as well as the refurbishment and commissioning of the Lone Tree autoclave and CIL processing facility. The Lone Tree refurbishment Class 3 engineering study remains on schedule for completion in the fourth quarter of 2025, followed by the feasibility study for Granite Creek Underground planned for completion in the first quarter of 2026.
Under the SEC’s mining disclosure rules in Subpart 1300 of Regulation S-K (“S-K 1300”), all of our properties are exploration stage as no mineral reserves have been determined.
Permitting
The current phase of permitting and development at Archimedes covers mining activities above the 5100-foot elevation, a threshold consistent with previously approved permits for open pit mining on the Property (see Figure 3
below). This phase of the Project is anticipated to provide development and production mining into the first half of 2028. Permitting activities below the 5100-foot elevation are underway with an estimated completion in the first half of 2027. This phased approach to permitting allows the Company to begin mining the Archimedes upper zone while simultaneously pursuing the remaining technical work and permits for the lower zone.
Development Work
The construction of surface infrastructure, such as a maintenance shop and offices, to support the Archimedes underground portal is complete (see Figure 4 below). Utilities such as water, power and compressed air are in place, and the highwall around the portals has been secured. Small Mine Development, L.L.C. (“SMD”) has been contracted to develop Archimedes to the 5100-foot elevation and is currently mobilized to advance the development drift. Underground development above the 5100-foot elevation is expected to be completed by mid-2027 and will include two underground portals, the main haulage decline, a series of raises for ventilation and secondary access, exploration bays and supporting infrastructure. The development contract with SMD is consistent with the cost estimates outlined in the Preliminary Economic Assessment of the Ruby Hull Project (“PEA”) filed on March 31, 2025.
Next Steps to Feasibility Study
The timing of the infill drill program and Archimedes feasibility study has been accelerated by approximately 12 months compared to the timing outlined in the PEA. Accelerating the drill program and feasibility study is expected to increase the cost of drilling by a range of approximately $10 million to $25 million primarily due to drilling from higher elevations resulting in longer drill holes.
Initial infill drilling of the upper zone is scheduled to begin from underground in the fourth quarter of 2025, followed by underground infill drilling of the lower zone planned in the first quarter of 2026. Collectively, these infill programs are anticipated to include more than 175 holes for approximately 60,000 meters of core. Results from the infill drilling will be included in a feasibility study which is targeted for completion in the first quarter of 2027.
The next steps will focus on three areas: resource drilling, permitting, and metallurgical testing. Resource conversion drilling will commence as the underground decline advances with results incorporated into an updated resource model. On permitting, related actions to meet National Environmental Policy Act and Nevada Department of Environmental Protection requirements for mining below the 5100-foot elevation will be carried out. Metallurgical test work will target initial Ruby Hill production areas to confirm metallurgical recoveries with the anticipated Lone Tree process conditions, including comminution, pressure oxidation under both alkaline and acidic conditions, and CIL testing on oxide material.
This anticipated Archimedes feasibility study will be prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) and S-K 1300 with an updated mineral resource estimate.

Endnotes
| (1) | Consolidated production estimates and average annual production targets include the Cove Project, Archimedes Underground Project, Mineral Point Open Pit Project, Granite Creek Underground Project, and Granite Creek Open Pit Project and are based on the most recent life-of-mine production schedules disclosed in the latest technical studies filed for each respective project and related property. These anticipated production figures are preliminary in nature and are based on mineral resources, which do not have demonstrated economic viability, and which are not mineral reserves. In addition, each of the foregoing technical reports are preliminary economic assessments/initial assessment that are preliminary in nature and each include an economic analysis that is based, in part, on inferred mineral resources. Inferred mineral resources are considered too speculative geologically to have for the application of economic considerations applied to them that would enable them to be categorized as mineral reserves. As such, there is no certainty that the production targets will be realized. The production target is also pending the completion of the autoclave refurbishment Class 3 engineering study (where a series of trade-off scenarios will be considered comparing full autoclave refurbishment to alternate toll milling and ore purchase agreement options that could potentially be available), Board approval, and the successful funding, development, and commissioning of the Company’s Lone Tree autoclave processing facility. The production target presented herein is a Company goal and not a projection of results and should not be taken as production guidance. |
