i-80 Gold (TSX: IAUX) is executing a methodical three-phase development plan designed to transform the company from a marginal Nevada gold producer into a profitable mid-tier operator generating 200,000 ounces annually by 2028 with projected EBITDA of $200 million to $300 million. The company's third quarter 2025 results marked a critical inflection point, delivering the strongest financial performance in company history whilst completing permanent dewatering infrastructure that had previously constrained access to higher-grade mineralisation at the flagship Granite Creek underground mine.

President and CEO Richard Young confirmed that permanent dewatering systems installed during Q3 2025 will enable accelerated underground development over the next six months into zones where "grades get better, ground conditions get better, and we expect mining rates to rise." A 47-hole infill drilling programme scheduled for completion in mid-December 2025 is yielding results that Young characterised as "consistently solid. Very good grades over very good widths," with a feasibility study incorporating these results expected at the end of Q1 2026 showing "materially better" economics than previous assessments.

Construction of the Archimedes underground mine commenced in Q3 2025, providing the second production centre necessary to justify the strategic refurbishment of i-80 Gold's Lone Tree autoclave facility. The autoclave refurbishment represents the pivotal value creation opportunity in management's development thesis. With current toll milling costs ranging between $1,000 and $1,500 per ounce, i-80 Gold is effectively surrendering $200 million to $300 million in annual EBITDA at the 2028 production target of 200,000 ounces. Young stated unequivocally: "Strategically and economically, that refurbishment is very important for us to move forward with."

Engineering firm Hatch has largely completed engineering work on the approximately $400 million autoclave refurbishment, with the board approving a $25 million limited notice to proceed authorising detailed engineering, long-lead equipment orders, and permitting initiation. The company expects to commence pouring gold through the refurbished autoclave before the end of 2027, creating an 18 to 24 month payback period on the capital investment at current gold prices.

Beyond Granite Creek and Archimedes, i-80 Gold completed infill drilling at its Cove underground project during Q3 2025, with results showing the total mineralised envelope up between 10 and 20 percent compared to previous estimates. A feasibility study is scheduled for Q1 2026, with permitting targeted for completion before the end of 2028. The company will release three major feasibility studies between Q1 2026 and Q1 2027 covering its core underground operations, each expected to show material improvements over preliminary economic assessments.

Management has received six term sheets from financing partners and is advancing toward recapitalisation completion by Q2 2026 to fund both phase one and phase two of the development plan. The company has successfully recruited experienced technical teams across mining engineering, metallurgy, and geology disciplines, a critical leading indicator of execution capability as i-80 Gold transitions from single-asset operator to multi-mine producer.

For investors evaluating Nevada-focused gold producers, i-80 Gold offers substantial leverage to successful execution and higher gold prices, with the 2028 target of 200,000 ounces production and $200-300 million EBITDA generation providing a concrete benchmark for measuring management's progress toward transformational value creation.
