Insights
i-80 Gold's development plan shows progress across five projects despite minor delays, positioning it well for incremental production growth through 2031.
i-80 Gold's development update reveals a methodical approach to transforming its Nevada asset portfolio into a mid-tier gold production platform. The company has established a clear sequential development roadmap with Granite Creek Underground as the first producing asset, followed by Archimedes (2026-2027), Cove (2029), Granite Creek Open Pit (late 2020s), and Mineral Point (2031).
The implementation of a predictive hydrogeological model at Granite Creek Underground represents a significant operational improvement, addressing previous dewatering challenges that likely impacted initial production ramp-up. This technical solution should provide more predictable mining conditions and potentially improve operational efficiency.
The company's sequential permitting strategy at Archimedes demonstrates pragmatic regulatory navigation, allowing mining to begin above the 5100-foot elevation while pursuing permits for deeper operations. This staged approach will accelerate initial production while mitigating permitting timeline risks.
The Lone Tree autoclave facility represents a strategic competitive advantage in Nevada's gold sector. As one of only three such facilities in the state, this asset provides i-80 with processing autonomy for its high-grade refractory material 鈥� a crucial capability as processing capacity in Nevada remains constrained.
While the update acknowledges minor timeline extensions for the South Pacific Zone feasibility study (Q1 2026 versus original Q4 2025) and Cove feasibility (Q1 2026 versus Q4 2025), these modest delays appear related to additional technical work rather than fundamental issues. Importantly, the company has maintained its broader production sequence milestones.
The advancement of infill drilling programs across multiple assets indicates the company is systematically de-risking its resource base ahead of development decisions. The substantial drilling campaign at Archimedes (175 holes, 60,000 meters) underscores the significance of this asset to the company's growth strategy.
i-80's expanded permitting team and ongoing regulatory engagement across its portfolio demonstrate appropriate prioritization of permitting as a critical path item for mining development in Nevada. This disciplined approach to permitting, feasibility studies, and sequential asset development positions i-80 for incremental production growth through 2031.
"We are making steady progress in laying the groundwork to bring i-80's industry-leading pipeline of high-grade projects into production over the coming years," stated Paul Chawrun, Chief Operating Officer of i-80 Gold. "Drilling is underway across several key properties聽as we prepare for upcoming feasibility studies, in addition to optimization work for the Lone Tree refurbishment study. At the same time, permitting efforts continue to gain momentum across our new projects, which we believe will help to de-risk our development pipeline."
Granite Creek Underground
Granite Creek Underground, i-80's first gold operation, continues to progress ramp-up activities toward steady state production. The implementation of a predictive hydrogeological model completed in the first quarter has enabled a more proactive dewatering of underground workings. The model has guided the management of mine contact water and the installation of permanent underground dewatering infrastructure planned through the remainder of the year, including additional surface wells and the installation of an expanded water treatment plant.
Infill drilling of the South Pacific Zone has commenced from both surface and underground following the completion of the underground exploration drift in the second quarter (see Figure 2 in Appendix). The infill campaign is expected to drill more than 40 holes for approximately 14,000 meters of core. In addition, a feasibility study is now underway, targeting completion in the first quarter of 2026, one quarter later than originally intended due to a delayed start to drilling. This feasibility study will incorporate an updated mineral resource estimate reflecting results from the current drill program.
Lone Tree Autoclave Processing Facility
Optimization of Lone Tree feasibility work is currently underway in collaboration with Hatch Ltd., an industry leader in autoclave technology, building on the internal feasibility study completed in 2023. The updated feasibility study for the facility's refurbishment will incorporate value engineering initiatives and updated cost estimates to support an improved execution strategy. Completion of the revised feasibility study is targeted for the fourth quarter of 2025. Concurrently, i-80 is recruiting the owner's team to oversee the engineering and execution of Lone Tree's refurbishment, along with risk mitigation planning and opportunities to accelerate the development timeline.
Lone Tree's existing processing facility is permitted, with the only additional permits and renewals required in the normal course being for the processing and environmental controls included in the refurbishment plan. Lone Tree is one of three autoclave facilities in
Archimedes Underground 鈥� Ruby Hill Property
At Archimedes, i-80's second planned underground mine, the final stages of permitting are nearing completion, with approval for advancement expected in the third quarter of 2025. This phase of permitting covers mining activities above the 5100-foot elevation, a threshold consistent with previously approved permits for open pit mining at Ruby Hill. Permitting below the 5100-foot elevation is expected to begin immediately upon receipt of the first phase of permits. This sequential approach to permitting expedites mining while simultaneously pursuing remaining permits for the lower section. Surface infrastructure for the external portal has been completed, and the initial development of the underground exploration drift is anticipated to commence shortly.
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 (see Figure 3 in Appendix). The upper zone will be the first to be mined as it is located above the 5100-foot elevation. 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 targeting completion in the first half of 2027. Archimedes is expected to begin contributing to production in late-2026 to early-2027.
Cove Underground
At Cove, the Company's third planned underground mine, infill drilling has been completed, and feasibility-level work is underway with feasibility study completion targeted for the first quarter of 2026, one quarter later than originally targeted in the development plan to accommodate additional metallurgical test work.
National Environmental Policy Act (NEPA) permitting activities are also underway with the Bureau of Land Management (BLM) in anticipation of an Environmental Impact Statement (EIS). i-80 is actively advancing major permit applications with the goal of aligning regulatory approvals with planned development timelines. The Company has recently expanded its permitting team and continues to work collaboratively with regulators and local stakeholders. Cove is expected to begin contributing to company-wide production in mid-2029.
Granite Creek Open Pit
Following the release of the Granite Creek Open Pit PEA, technical work is underway to advance the project toward either a pre-feasibility or a feasibility-level study. Simultaneously, trade off analyses are being conducted to optimize the economics of the project. Permitting work is in the initial stages and advancing as expected. Granite Creek Open Pit has the potential to contribute to company-wide production by the end of the decade.
Mineral Point Open Pit 鈥� Ruby Hill Property
Mineral Point, an oxide heap leach project, is an earlier stage project within i-80's portfolio of assets. Mineral Point has the potential to become the Company's largest producing asset and is expected to provide the biggest step change in company-wide production starting the second half of 2031. Core drilling was initiated in June to support ongoing hydrological, geological and geotechnical assessments. The results are expected to support the mine design and metallurgical studies as part of advancing the project toward the next stage of technical evaluation. Following the release of a PEA in the first quarter of 2025, strategic evaluations are underway to determine optimal timing of a pre-feasibility or feasibility-level study.
