Production and sales totaled 2,486 gold ounces for the quarter at a realized gold price of $2,083 per ounce sold¹. Additionally, mineralized material sales totaled 10,167 tons for the quarter for proceeds of $3.2 million.

Exploration, evaluation, and pre-development costs were $2.8 million for the quarter. This expenditure mainly reflects the exploration and pre-development work at McCoy-Cove and Ruby Hill.

Granite Creek

Highlights for the three months ended March 31, 2024, include:

• 10,167 tons of mineralized material sold under the Ore Sale Agreement for proceeds of $3.2 million.

• 28,500 tons of mineralized material added to stockpile, bringing the total stockpile material to 37,907 tons before sales.

• 3,178 feet of horizontal development.

Management of increased groundwater inflows into the underground workings continues to be a top priority. Dewatering Well #6 was completed and is in operation, and a second contact water discharge line was commissioned from the underground workings.

McCoy-Cove

The Cove deposit and the McCoy-Cove Property is expected to be the core asset in the Company's "hub and spoke" business plan and likely the highest-grade gold deposit in i-80's portfolio. During the quarter the Company achieved high grade infill drilling results at Helen and Gap Zones with 3,594 feet of total drilling completed.

Ruby Hill

During the quarter drilling at Ruby Hill was focused on infill drilling of the Hilltop zones for metallurgical sampling in relation to the previously announced potential joint venture. 4,032 feet of core drilling was completed during the quarter, fully funded by the potential joint venture partner in order to complete due diligence during the exclusivity period. Drilling highlights for the quarter include:

• 0.2% Zn, 6.3% Pb, 180.0 g/t Ag & 2.2 g/t Au Over 5.0 m in hole iRH24-01

• 6.2% Zn, 5.6% Pb, 198.0 g/t Ag & 1.0 g/t Au Over 3.6 m and 13.4% Zn, 2.5% Pb, 93.7 g/t Ag, & 0.6 g/t Au over 5.5 m in hole iRH24-02

• 13.7% Zn, 0.6% Cu, & 17.5 g/t Ag Over 57.8 m in hole iRH24-03

Residual leaching activities at Ruby Hill produced and sold 444 ounces of gold during the quarter at a realized gold price of $2,016 per ounce sold^1. As the heap leach pad is nearing the end of its production cycle the Company continues to analyze the breakeven cost and anticipates that the heap leach pad will cease production in 2024.

Lone Tree

Lone Tree is expected to become the hub of i-80's Nevada operations and the central processing facility for gold mineralization from the Granite Creek, McCoy-Cove and Ruby Hill underground gold deposits. Importantly, Lone Tree is host to infrastructure that, following successful refurbishment efforts, will position i-80 as one of only three companies in the United States capable of processing both oxide and refractory mineralization.

During the quarter the Company continued its review of the value engineering studies and total refurbishment costs for the autoclave.

Lone Tree produced and sold from its residual leaching activities 2,042 ounces of gold during the quarter at a realized gold price of $2,097 per ounce sold^1.

NON-IFRS FINANCIAL PERFORMANCE MEASURES

The Company has included certain terms or performance measures commonly used in the mining industry that are not defined under IFRS in this document. These include: adjusted net earnings and average realized price per ounce. Non-IFRS financial performance measures do not have any standardized meaning prescribed under IFRS, 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 and should be read in conjunction with the Company's Financial Statements.

Definitions

Adjusted earnings / (loss) and adjusted earnings / (loss) per share excludes from net earnings / (loss) significant write-down adjustments and the gain / (loss) from financing instruments.

Average realized gold price represents the sales price of gold per ounce before deducting mining royalties, treatment and refining charges and gains or losses derived from the offtake agreement with Orion.

Average realized gold price per ounce of gold sold

Average realized gold price per ounce of gold sold is a non-IFRS measure and does not constitute a measure recognized by IFRS and does not have a standardized meaning defined by IFRS. It may not be comparable to information in other gold producers' reports and filings.

Adjusted loss

Adjusted loss and adjusted loss per share are non-IFRS measures that the Company considers to better reflect normalized earnings because it eliminates non-recurring items. Certain items that become applicable in a period may be adjusted for, with the Company retroactively presenting comparable periods with an adjustment for such items and conversely, items no longer applicable may be removed from the calculation. Neither adjusted loss nor adjusted loss per share have any standardized meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other companies.

The following table shows a reconciliation of adjusted loss to the net earnings / (loss) for each period. Adjusted loss and adjusted loss per share exclude a number of temporary or one-time items detailed in the following table:
