i-80 Gold Provides a Development Update; Archimedes Underground and Lone Tree Plant Refurbishment Remain on Track and Mineral Point Open Pit Prioritized in Updated Development Plan

i-80 Gold targets 150,000–200,000 oz annual gold output by 2028, scaling to 600,000 oz in 2030s.

What the company is saying

i-80 Gold Corp. presents a detailed update on its Nevada gold development pipeline, emphasizing that all major projects remain on schedule and largely on budget. The company frames its narrative around becoming a Nevada-focused mid-tier gold producer, with a phased plan anchored by the Lone Tree Plant refurbishment and a hub-and-spoke mining model. Management, led by President & CEO Richard Young and COO Paul Chawrun, highlights technical progress, resource expansion—specifically a 230% increase in Granite Creek underground measured and indicated resources—and the reprioritization of Mineral Point open pit as the next major development. The announcement stresses cost discipline, citing only 10% of project contingency drawn and cash expenditures trending below $140–$160 million guidance, while acknowledging labor cost pressures of 5–10% above initial estimates. The company claims significant future cost savings at Lone Tree ($1,000–$1,500/oz) and targets a production ramp from 150,000–200,000 oz/year in 2028 to 500,000–600,000 oz/year in the early 2030s. The tone is confident, with forward-looking milestones and technical studies outlined, but most production and economic benefits are still projections.

What the data suggests

The company discloses a $430 million capital cost estimate for the Lone Tree Plant, with 12% contingency included, and reports that 44% of capital is committed and 74% of procurement packages awarded by value. Bulk demolition at Lone Tree is complete, and construction mobilization is set for Q4 2026, with first gold pour targeted for Q4 2027. Only 10% of contingency has been used, and cash expenditures are below the $140–$160 million 2026 guidance, though labor costs are running 5–10% higher than planned. Granite Creek underground's measured and indicated resources have increased by 230% per the September 2026 feasibility study, supporting the company's view of extended mine life and feed flexibility. Mineral Point open pit is projected to add 280,000 gold equivalent ounces annually over 17 years, based on a March 2025 PEA. The Lone Tree Plant is expected to reduce third-party processing costs by $1,000–$1,500 per ounce. Production targets are 150,000–200,000 oz/year from 2028, 400,000–500,000 oz/year from 2031 (with Mineral Point), and 500,000–600,000 oz/year in the early 2030s (with Granite Creek open pit). Permitting is advanced, with all major state and federal permits in place for Lone Tree. Most claims are forward-looking and contingent on successful construction, commissioning, and future technical study outcomes.

Analysis

The announcement is highly positive in tone, emphasizing ambitious production targets (150,000–200,000 oz/year by 2028, scaling to 500,000–600,000 oz/year in the early 2030s) and major project milestones. However, the majority of key claims are forward-looking, with realized progress limited to bulk demolition at Lone Tree, some procurement, and a reported 230% resource increase at Granite Creek. The largest benefits—substantial production growth and cost reductions—are not expected until 2028–2030+, and depend on successful completion of multi-year, capital-intensive projects (notably the $430M Lone Tree Plant refurbishment, of which only 44% of capital is committed). While capital spend is reportedly on budget and technical studies are advancing, there is no disclosure of current revenue, profit, or cash flow, and most operational improvements remain projections. The language inflates the signal by presenting targets and potentials as near-certainties, despite the long execution timeline and ongoing technical/financing risks.

Risk flags

• ●Execution risk is high due to the long timeline and capital intensity: the Lone Tree Plant refurbishment alone requires $430 million, with only 44% of capital committed and construction not yet started. Delays or overruns could materially impact the schedule and cost structure.
• ●Production targets rely on successful completion and integration of multiple projects: the ramp from 150,000–200,000 oz/year to 500,000–600,000 oz/year depends on timely delivery of Archimedes underground, Mineral Point open pit, and Granite Creek open pit, each with separate technical and permitting hurdles.
• ●Cost inflation risk is present: labor costs are already running 5–10% above initial estimates, and while within contingency, sustained inflation or supply chain issues could erode margins or require additional capital.
• ●Resource and technical risk remains: key production and cost-saving assumptions are based on preliminary studies (PEAs and feasibility studies in progress), and actual recoveries, grades, or metallurgical performance could fall short of projections.
• ●Financing risk is flagged by the company's ongoing discussions with lenders for a revolving credit facility, indicating that additional liquidity may be needed to execute the full development plan.

Bottom line

i-80 Gold is advancing a multi-asset Nevada gold plan with a clear sequence: ramping up Granite Creek underground, bringing Archimedes underground online, and refurbishing the Lone Tree Plant as a central processing hub. The company claims it will achieve 150,000–200,000 oz/year gold production by 2028 and scale to 500,000–600,000 oz/year in the early 2030s, but these are long-term targets contingent on successful execution of several capital-intensive projects. The Lone Tree Plant refurbishment is progressing, with $430 million budgeted and 44% of capital committed, but construction is only just commencing. Technical progress is evident, especially at Granite Creek, but most of the projected value remains unrealized and subject to further study outcomes and permitting. Investors should focus on near-term milestones: Lone Tree construction start in Q4 2026, Archimedes mining in Q4 2026, and Lone Tree's first gold pour in Q4 2027. The most important takeaway is that while management is meeting interim milestones and controlling costs so far, the bulk of the value is several years and multiple execution steps away.

Announcement summary

(NYSE:IAUX) (TSX:IAU) i-80 Gold Corp. provided a comprehensive update on its Nevada development plan, confirming that operating and near-term development projects are advancing on schedule toward a total annual production target of 150,000 to 200,000 ounces of gold starting in 2028. The company has updated its development plan to prioritize the Mineral Point open pit as the next major project after establishing its underground hub-and-spoke mining and processing platform. Archimedes underground mine development is progressing as planned, with production mining expected to commence in the fourth quarter of 2026. The Lone Tree Plant refurbishment is advancing, with bulk demolition completed and initial construction activities set to begin in Q4 2026. Capital expenditures remain largely on budget, with approximately 10% of the total project contingency drawn down to date. The Mineral Point open pit is projected to add approximately 280,000 gold equivalent ounces of annual production over a 17-year mine life, based on the March 2025 PEA. Ongoing metallurgical test work at Archimedes underground's 426 zone indicates potential for low-cost oxide processing on the Ruby Hill heap leach pad, which was not included in the March 2025 PEA. Richard Young, President & CEO, stated that Granite Creek underground's measured and indicated mineral resources increased by approximately 230% in the September 2026 feasibility study compared to the March 2025 PEA. The Lone Tree Plant refurbishment is on track, with a first gold pour targeted for Q4 2027. Paul Chawrun, Executive Vice President and COO, highlighted the resource expansion potential at Granite Creek and Archimedes underground, supporting the supply of refractory feed to the Lone Tree Plant for longer than previously contemplated. The broader development plan targets 500,000 to 600,000 ounces of average annual gold production in the early 2030s. The Lone Tree Plant is expected to reduce third-party processing costs by $1,000 to $1,500 per ounce of gold, depending on grade and gold price, based on the December 2025 engineering study. The total capital cost estimate for the Lone Tree Plant refurbishment is $430 million, including approximately 12% contingency, owner's cost, and capital spares. Cash expenditures to date are trending below the 2026 guidance of $140 million to $160 million. Labor costs are running approximately 5% to 10% above initial estimates but remain within contingency. Approximately 44% of capital was committed by the end of Q3 2026, and about 74% of procurement packages by value were awarded as of September 2026. The plant is federally permitted, with state permits received on schedule. Lone Tree is expected to process approximately 2,250 tonnes per day, or 825,000 tonnes per annum, at 85% availability. The updated plan sequences Granite Creek underground ramp-up, Archimedes underground production, and Lone Tree Plant commissioning, followed by Mineral Point open pit development, then Granite Creek open pit and Cove underground. The September 2026 Granite Creek feasibility study reported a 230% increase in measured and indicated underground mineral resources compared to the March 2025 PEA. Annual gold production is targeted at 150,000 to 200,000 ounces beginning in 2028, increasing to 400,000 to 500,000 ounces in 2031 with Mineral Point open pit, and 500,000 to 600,000 ounces in the early 2030s with Granite Creek open pit. Mineral Point is described as the company's largest and most valuable project, hosting a large undeveloped bulk-mineable oxide gold-silver resource. Infill and step-out drilling are supporting a planned pre-feasibility study in mid-2027. The company is in dialogue with lead lenders to establish a corporate revolving credit facility for additional liquidity if needed. An analyst site tour is scheduled for October 14-15, 2026. Upcoming milestones include Lone Tree Plant construction commencement in Q4 2026, filtration plant completion in early Q4 2027, and first gold pour in Q4 2027; Archimedes underground first gold mined in Q4 2026; feasibility studies for Cove underground and Archimedes underground by Q4 2026 and mid-2027, respectively; and Mineral Point and Granite Creek open pit pre-feasibility studies by mid-2027 and timing under review, respectively.
