"The release of the Archimedes PEA marks another step forward in our plan to establish i-80 Gold's broader hub-and-spoke mining and processing strategy in northeastern Nevada. Based on the PEA, Archimedes is expected to contribute meaningfully to the overall production and economics of the Company's hub-and-spoke strategy in spite of higher transportation costs to our central autoclave facility, and lower grades relative to the Company's two other underground projects. The PEA's findings show that at a base case gold price of $2,175/oz, Archimedes Underground is at the lower end of valuation compared to other underground gold projects in our portfolio, however it presents the highest leverage to gold prices," stated Richard Young, Chief Executive Officer.
PEA Highlights
Mineral Estimates, Production and Mine Life
- High-grade underground gold mine with a life of mine ("LOM") of approximately 10 years.
- Average annual gold production of approximately 100,000 ounces of gold following ramp up.
- Estimated LOM cash costs(1) of $1,769 per ounce and all-in-sustaining costs(1) of $1,893 per ounce.
- Updated mineral resource estimate resulting in an indicated gold mineral resource of 436,000 ounces at 7.6 grams per tonne ("g/t") and an inferred gold mineral resource of 988,000 ounces at 7.3 g/t.
- All drilling conducted within the Archimedes underground area since the property's acquisition in 2021, is included in the PEA. Additional infill drilling is expected to be completed from the underground on the Ruby Deeps and the 426 zone in 2027 to be included in a planned feasibility study in 2028.
- Several exploration targets to be followed up on in the coming years to potentially extend the mine life beyond the current 10 years.
Project Economics
- Based on a $2,175/oz gold price, the Project's undiscounted after-tax cash flows(2)(3) total $212 million with an after-tax net present value(2)(3) ("NPV") of $127 million, assuming a 5% discount rate, generating a 23% internal rate of return ("IRR").
- Based on a spot gold price of $2,900/oz, the Project's undiscounted after-tax cash flows(2)(3) total $902 million with an after-tax NPV(2)(3) of $581 million, assuming a 5% discount rate, generating a IRR of 75%.
- Mine construction capital is estimated at $49 million.
- LOM development and sustaining capital is estimated at $106 million.
Mining and Processing
- Long hole open stoping with delayed backfill is the primary planned mining method.
- Approximately 90% of the material mined is anticipated to be processed at i-80 Gold's Lone Tree autoclave facility (see Figure 1) starting in 2028. The remainder is expected to be processed at a third-party autoclave facility in 2026 and 2027, as well as the property's heap leach facility.
- Overall average gold grade processed of 7.0 g/t with an average gold recovery of 90% (autoclave) and an average expected heap leach grade of 3.8 g/t gold with an average recovery of 87%.
All amounts are in United States dollars, unless otherwise stated.

"The Archimedes PEA reinforces its value within i-80 Gold's portfolio, with the potential to achieve the highest mining rate among our underground operations. The geometry of the mineralized body supports the use of bulk mining methods, driving lower unit costs and enhancing project economics. Additionally, extensive infrastructure is already in place, and the sequential permitting approach allows us to expedite mining activities through mid-2027, while finalizing approvals for the lower section," added Matthew Gili, President and Chief Operating Officer.
Mineral Resource Update
The PEA includes all drilling conducted on the Archimedes underground since i-80 Gold's acquisition of the property. The updated mineral resource estimate includes a total of 436,000 ounces of gold at 7.6 g/t Au in the indicated category and 988,000 ounces of gold at 7.3 g/t Au in the inferred category (see Table 2). The majority of the resource estimate is currently hosted in the Ruby Deeps deposit (see Figure 1). The mineral resource estimate is based on stope optimization software. This methodology is more accurate than previous estimation techniques and has become the industry standard for underground deposits in Nevada.
The updated resource estimate includes all drilling since 2021, as well as stope optimization which results in additional mineralized body constraints. Overall, the indicated resource tonnes and gold ounces have increased by 49% and 116%, respectively, as compared to the 2021 resource estimate resulting in a total of 436,000 indicated gold ounces contained. The increase in indicated ounces is offset by a decline in inferred tonnes and ounces by 49% and 37%, respectively, resulting in a total of 988,000 inferred ounces contained. Gold grades have increased in all categories of resource, improving by 46% in the indicated category and 21% in the inferred category.
Once the underground drill platforms are constructed, a significant infill drill program is planned for Ruby Deeps and the 426 zone in the coming years to follow up on earlier positive results in a more cost-effective manner with the goal of extending the mine life beyond the current 10 years. Ruby Deeps remains open to the north and south, offering substantial exploration potential.
An updated mineral resource estimate is expected to be completed in 2028 for inclusion in a planned feasibility study. The updated resource is expected to include 50,000 meters of drilling, of which the majority is infill drilling to define reserves, targeting the 426 zone and the Ruby Deeps scheduled for 2027.

Project Overview
Archimedes is located along the southeastern end of the Battle Mountain/Eureka gold trend. The Project is a component of the broader Ruby Hill Complex and an extension of the historically mined open pit, which was a major past-producing asset. During the 1990s, an ore body was discovered, which became the Archimedes Pit. Later discoveries included the Ruby Deeps sulfide deposit with the most recent discovery of the polymetallic Hilltop zone.
The Complex also includes the Mineral Point deposit, an open pit heap leach project, as well as several base metal deposits. Mineral Point is a large oxide gold and silver deposit with the potential to become the Company's largest gold producing asset. An updated PEA for the Mineral Point open pit project is expected to be completed in the first quarter of 2025. Processing infrastructure at the Complex includes a primary and secondary crushing plant, grinding mill, leach pad, and carbon-in-column circuit, which are designed to process oxide material. The Archimedes deposit is composed of single refractory sulfide material, which is not amenable to the facilities at the Complex, and therefore, will be trucked to the Company's Lone Tree property.
Geology and Mineralization
The Archimedes underground deposit is comprised of the Ruby Deeps and 426 zone, which are located immediately northwest and below the historic Archimedes Pit (see Figure 1). Both the 426 zone and Ruby Deeps consist of Carlin-Type mineralization, characterized by fine-grained pyrite with gold bearing arsenic-rich rims. In the 426 zone, mineralization is primarily located in the lower laminated portion of the Ordovician Goodwin limestone along the northeast striking 426 fault zone. The 426 zone is generally flat-lying and consists of a mixture of oxide and sulfide material. At Ruby Deeps, mineralization is found in the Cambrian Windfall limestone, Dunderberg shale, and a Cretaceous granodiorite sill, in the hanging-wall of the north striking Holly fault. The mineralized zone in Ruby Deeps is generally flat-lying and consists entirely of sulfide material.
Mining and Processing
The PEA demonstrates an initial 10-year mine life with average annual gold production of approximately 100,000 ounces of gold following ramp up. The PEA represents a preliminary point-in-time estimate of the mine plan.
Underground access will be through twin portals located in the north wall of the Archimedes Pit adjacent to the pit haulage ramp. The main decline will provide personnel and equipment access to all areas of the mine and will be wide enough to accommodate 30-ton haul trucks.
Long hole open stoping ("LHOS") with delayed backfill is the primary mining method planned for Ruby Hill. Drift and fill mining can be implemented when the mineralization geometry does not have sufficient vertical extent to allow LHOS, sill mining, or where ground conditions will not maintain vertical stope walls. Underhand drift and fill mining is preferred since the backfill quality will be better than the rock quality.
While a small component of the upper levels of the 426 zone contains oxide mineralization, metallurgical testing has demonstrated that both the 426 and Ruby Deep zones of the Archimedes Underground are generally single refractory and require an oxidation process to increase gold extraction using whole cyanidation of mineralized material. Additionally, testing has demonstrated that the gold recovery for both deposits is materially higher when an autoclave is operated in the acidic environment.
The PEA incorporates toll-milling arrangements with associated over-the-road trucking costs for the years 2026 and 2027. Starting in 2028, the processing costs and recoveries associated with hauling to and processing at the Lone Tree autoclave in the acidic environment have been incorporated into the PEA. Processing materials in the acidic environment increases per tonne processing costs by approximately $35; however, the additional cost is offset by higher recovery rates. The oxide mineralization from the 426 zone will be processed via heap leach at the existing Complex leach pad, with the associated recoveries applied. A LOM processing schedule is illustrated in Figure 4.
Capital Cost Summary
Mine construction capital is estimated to be $49 million.
Archimedes benefits from the extensive facilities and infrastructure that remains from the Archimedes Pit. The majority of the capital budget, including mine construction and sustaining, is associated with mine development. Construction of the underground portals and associated near portal facilities is budgeted at $8.6 million. These activities are currently underway in preparation for commencement of underground development early in the second quarter of 2025.
Archimedes is expected to generate an estimated $212 million in after-tax cash flow over the current 10-year mine life (see Figure 5).

Permitting
The phased permitting process at Archimedes is well underway, allowing for simultaneous mining while permitting for the next phase progresses. The initial phase covers mining activities above the 5100-foot elevation, a threshold consistent with previously approved permits for open pit mining at Ruby Hill. The first phase of permitting is nearing completion and once finalized, will allow for mining through June 2027.
The second phase of permitting covers mining below the 5100-foot elevation and is set to begin immediately upon receipt of the first phase of permits. This phase is scheduled for completion by the end of the second quarter 2027, with the objective of ensuring uninterrupted mining at the Project.
National Environmental Policy Act ("NEPA") associated permitting activities continue to progress. Amended Plan of Operations and Environmental Assessment documents have been provided to the Bureau of Land Management ("BLM") with the next step being completion of the Decision Record (DR). Nevada Division of Environmental Protection ("NDEP") permitting activities are also progressing, focusing on the site's Water Pollution Control Permits. Both the NEPA and NDEP permits are expected at the end of the first quarter of 2025.
Next Steps to Feasibility Study
A feasibility study in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and Subpart 1300 of Regulation S-K ("S-K 1300") with an updated mineral resource estimate is expected to be completed in 2028. The updated resource is expected to include 50,000 meters of drilling targeting the 426 zone and the Ruby Deeps. Below is a summary of additional work to be conducted.
Resource Delineation and Exploration
- Begin resource conversion drilling as decline advances and drill platforms become available. Incorporate this data into an updated resource model.
Permitting
- Complete the NEPA and NDEP permitting amendments for mining below the 5100 foot elevation.
Metallurgical Testing
Additional metallurgical testing is required from the initial Ruby Hill production areas to confirm metallurgical recoveries with Lone Tree autoclave process conditions. Sample selection will be based on available mine production plans to reflect typical stope dimensions and expected dilution. Testing will include:
- Comminution testing to confirm throughput through the Lone Tree mill.
- Additional pressure oxidation tests using both alkaline and acidic pressure oxidation conditions for the Lone Tree autoclave.
- Carbon-in-leach tests on pressure oxidation productions.
Technical Disclosure and Qualified Persons
The PEA was prepared in accordance with NI 43-101. The full PEA will be filed within 45 days under the Company's issuer profile on SEDAR+ at www.sedarplus.ca and on i-80 Gold's profile. An Initial Assessment for the Archimedes Underground Project ("S-K 1300 Report") was also prepared in accordance with S-K 1300 and Item 601 of the Regulation S-K and the S-K 1300 Report will be filed on EDGAR at www.sec.gov. Both reports will be available on the Company's website at www.i80gold.com. The mineral estimates and project economics are the same under the PEA and the S-K 1300 Report.
The technical information contained in this press release has been prepared under the supervision of, and has been reviewed and approved by Dagny Odell, P.E., (SME No. 2402150) Practical Mining LLC, and Tyler Hill CPG., Vice President Geology for the Company, who are all qualified persons within the meaning of NI 43-101 and S-K 1300.
For a description of the data verification, assay procedures and the quality assurance program and quality control measures applied by the Company, please see the Company's Annual Information Form dated March 12, 2024 filed under the Company's profile on SEDAR+ at www.sedarplus.ca and filed with the Company's Form 40-F under the Company's profile on EDGAR at www.sec.gov. Further information about the PEA referenced in this news release, including information in respect of data verification, key assumptions, parameters, risks and other factors, will be contained in the PEA.
The PEA is preliminary in nature and includes an economic analysis that is based, in part, on inferred mineral resources. Inferred mineral resources that 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, and there is no certainty that the results of the PEA will be realized. Mineral resources do not have demonstrated economic viability and are not mineral reserves.

Forward-Looking Information
Certain statements in this release constitute "forward-looking statements" or "forward-looking information" within the meaning of applicable securities laws, including but not limited to, statements regarding the updated results of the PEA on the Project, such as future estimates of internal rates of return, net present value, future production, estimates of cash cost, proposed mining plans and methods, mine life estimates, cash flow forecasts, metal recoveries, estimates of capital and operating costs, timing for permitting and environmental assessments, timing, completion and results of feasibility studies, and the size and timing of phased development of the Project. Furthermore, forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by the Company as of the date of such statements, are inherently subject to significant business, economic and competitive uncertainties and contingencies. With respect to this specific forward-looking information concerning the development of the Project, the Company has based its assumptions and analysis on certain factors that are inherently uncertain. Uncertainties include: (i) the adequacy of infrastructure; (ii) geological characteristics; (iii) metallurgical characteristics of the mineralization; (iv) the ability to develop adequate processing capacity; (v) the price of gold, silver and other commodities; (vi) the availability of equipment and facilities necessary to complete development; (vii) the cost of consumables and mining and processing equipment; (viii) unforeseen technological and engineering problems; (ix) natural disasters and/or accidents; * currency fluctuations; (xi) changes in regulations; (xii) the compliance by and/or key suppliers with terms of agreements; (xiii) the availability and productivity of skilled labour; (xiv) the regulation of the mining industry by various governmental agencies, including permitting and environmental assessments; (xv) the ability to raise sufficient capital to develop such projects; (xiv) changes in project scope or design; and (xv) political factors.
Such statements can be identified by the use of words such as "may", "would", "could", "will", "intend", "expect", "believe", "plan", "anticipate", "estimate", "scheduled", "forecast", "predict" and other similar terminology, or state that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved. These statements reflect the Company's current expectations regarding future events, performance and results and speak only as of the date of this release and are expressly qualified in their entirety by this cautionary statement. Subject to applicable securities laws, the Company does not assume any obligation to update or revise the forward-looking statements contained herein to reflect events or circumstances occurring after the date of this release.
This release also contains references to estimates of mineral resources. The estimation of mineral resources is inherently uncertain and involves subjective judgments about many relevant factors. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation (including estimated future production from the Project, the anticipated tonnages and grades that will be mined and the estimated level of recovery that will be realized), which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. Mineral resource estimates may have to be re-estimated based on: (i) fluctuations in commodities prices; (ii) results of drilling, (iii) metallurgical testing and other studies; (iv) proposed mining operations, including dilution; (v) the evaluation of mine plans subsequent to the date of any estimates; and (vi) the possible failure to receive required permits, approvals and licenses or changes to existing mining licenses.
Forward-looking statements and information involve significant known and unknown risks and uncertainties, should not be read as guarantees of future performance or results and will not necessarily be accurate indicators of whether or not such results will be achieved. A number of factors could cause actual results to differ materially from the results expressed or implied by such forward-looking statements or information, including, but not limited to: the Company's ability to finance the development of its mineral properties; assumptions and discount rates being appropriately applied to the PEA and S-K 1300 Report, uncertainty as to whether there will ever be production at the Company's mineral exploration and development properties; risks related to the Company's ability to commence production at the Project and generate material revenues or obtain adequate financing for its planned exploration and development activities; uncertainties relating to the assumptions underlying resource and reserve estimates; mining and development risks, including risks related to infrastructure, accidents, equipment breakdowns, labour disputes, bad weather, non-compliance with environmental and permit requirements or other unanticipated difficulties with or interruptions in development, construction or production; the geology, grade and continuity of the Company's mineral deposits; the uncertainties involving success of exploration, development and mining activities; permitting timelines; government regulation of mining operations; environmental risks; unanticipated reclamation expenses; prices for energy inputs, labour, materials, supplies and services; uncertainties involved in the interpretation of drilling results and geological tests and the estimation of reserves and resources; unexpected cost increases in estimated capital and operating costs; the need to obtain permits and government approvals; material adverse changes, unexpected changes in laws, rules or regulations, or their enforcement by applicable authorities; the failure of parties to contracts with the company to perform as agreed; social or labour unrest; changes in commodity prices; and the failure of exploration programs or studies to deliver anticipated results or results that would justify and support continued exploration, studies, development or operations. For a more detailed discussion of such risks and other factors that could cause actual results to differ materially from those expressed or implied by such forward-looking statements, refer to i-80 Gold's filings with Canadian securities regulators, including the most recent Annual Information Form, available on SEDAR+ at www.sedarplus.ca.
Non-IFRS/Non-GAAP Financial Performance Measures
The Company has included certain terms or performance measures in this news release that commonly used in the gold mining industry that are not defined under International Financial Reporting Standards ("IFRS") or United States Generally Accepted Accounting Principles ("US GAAP"). This includes: all-in sustaining costs per ounce and cash cost per ounce. Non-IFRS/Non-GAAP financial performance measures do not have any standardized meaning prescribed under IFRS or US GAAP, and therefore, they may not be comparable to similar measures employed by other companies. The data presented is intended to provide additional information and should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS US GAAP and should be read in conjunction with the Company's financial statements. Because the Company has provided these measures on a forward-looking basis, it is unable to present a quantitative reconciliation to the most directly comparable financial measure calculated and presented in accordance with IFRS or US GAAP without unreasonable efforts. This is due to the inherent difficulty of forecasting the timing or amount of various reconciling items that would impact the most directly comparable forward-looking IFRS or US GAAP measure that have not yet occurred, are outside of the Company's control and/or cannot be reasonably predicted.
Definitions
"All-in sustaining costs" is a non-IFRS or US GAAP financial measure calculated based on guidance published by the World Gold Council ("WGC"). The WGC is a market development organization for the gold industry and is an association whose membership comprises leading gold mining companies. Although the WGC is not a mining industry regulatory organization, it worked closely with its member companies to develop these metrics. Adoption of the all-in sustaining cost metric is voluntary and not necessarily standard, and therefore, this measure presented by the Company may not be comparable to similar measures presented by other issuers. The Company believes that the all-in sustaining cost measure complements existing measures and ratios reported by the Company. All-in sustaining cost includes both operating and capital costs required to sustain gold production on an ongoing basis. Sustaining operating costs represent expenditures expected to be incurred at the Project that are considered necessary to maintain production. Sustaining capital represents expected capital expenditures comprising mine development costs, including capitalized waste, and ongoing replacement of mine equipment and other capital facilities, and does not include expected capital expenditures for major growth projects or enhancement capital for significant infrastructure improvements.
"Cash cost per gold ounce" is a common financial performance measure in the gold mining industry but has no standard meaning under IFRS or US GAAP. The Company believes that, in addition to conventional measures prepared in accordance with IFRS or US GAAP, certain investors use this information to evaluate the Company's performance and ability to generate cash flow. Cash cost figures are calculated in accordance with a standard developed by The Gold Institute. The Gold Institute ceased operations in 2002, but the standard is considered the accepted standard of reporting cash cost of production in North America. Adoption of the standard is voluntary, and the cost measures presented may not be comparable to other similarly titled measures of other companies.

Notes to table above: (1) A portion of the drilling capital ($2.1M) is included in construction capital, while the remaining $8.5M is classified as sustaining capital. (2) The annual calculation for all-in sustaining costs include reclamation costs on a cash basis rather than on an accrual basis. As such, the weighted average of the annual all-in sustaining costs amounts will not agree to the life of mine all-in sustaining costs. |
