2023 First Quarter Highlights:

• Q1 2023 gold sales of 2,349 ounces, including the first gold sold from the Granite Creek property
• March 31 cash balance of $57 million and $33 million in restricted cash
• Continued exploration success at Ruby Hill including multiple new high-grade discoveries and expansion of gold and polymetallic mineralization
• 6,890 core feet and 320 RC feet drilled to expand monitoring of the hydraulic properties at McCoy Cove
• Continued underground core drilling delineation of the CSD Gap ore body at McCoy Cove (10,699 feet)
• 9,389 tons of oxide mineralized material shipped to Lone Tree from Granite Creek for processing
• Entered into an agreement to acquire Paycore Minerals Inc.
• Engineering Class III study of Lone Tree autoclave refurbishment continued on plan

"We are encouraged to have achieved the milestone of our first gold sale from Granite Creek, with over 400 ounces sold. We continue to advance development and improve production capabilities at this site and expect a ramp up through 2023. In addition, we continued to have production from the residual leaching at both Lone Tree and Ruby Hill", stated Ryan Snow, Chief Financial Officer of i-80. "We continued to advance development at McCoy-Cove and exploration at Ruby Hill spending nearly $9.0 million during the quarter to further understand the Hilltop and Blackjack zones at Ruby Hill and the CSD Gap ore body at McCoy Cove. With the additional capital raise completed in February, we will continue to advance i-80's projects towards our ultimate goal of being a mid-tier Nevada focused producer."

Production and sales totaled 2,349 gold ounces for the quarter at a realized gold price of $1,927¹ per ounce sold.

Exploration, evaluation, and pre-development costs were $9.0 million in Q1. This expenditure mainly reflects the exploration and pre-development work at McCoy Cove and Ruby Hill.

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 leaching the residual material on the pads as planned and shipped approximately 1,950 ounces of gold on loaded carbon from site to further processing. Additionally, the Company continued to advance the engineering study and cost estimate for the restart of the autoclave.

Lone Tree produced and sold from its residual leaching activities 663 ounces of gold during Q1 at a realized gold price of $1,962¹ per ounce sold.

Granite Creek

During Q1 the Company continued its efforts to upgrade existing de-watering infrastructure to ensure efficient operations and have mined 16,648 tons of mineralized material at an average grade of 9.9 g/t, of which 9,389 tons of oxide material was hauled to the Lone Tree leach pad to continue processing. As of March 31, 2023, 1,870 feet of development were completed as part of the Company's ramp up plan.

Granite Creek produced and sold 444 ounces of gold during Q1, at a realized gold price of $1,938¹ per ounce sold.

McCoy-Cove

There was 7,210 feet of core and RC drilling conducted during the first quarter of 2023 for hydrogeologic characterization to support permitting efforts. Underground delineation drilling continued during Q1 with 10,699 feet of core drilled. Expenditures continued during the quarter on the exploration ramp and hydrology studies, and engineering of de-watering and mining options. As of the end of the first quarter, development footage completed was 1,308 feet. Total footage development of the project life as of Q1 2023 is 4,403 feet.

Ruby Hill

During the first quarter of 2023, drilling at Ruby Hill was primarily focused on further definition and expansion of high-grade polymetallic mineralization along the Hilltop fault structure, successfully extending mineralization over a strike length of approximately 750 metres and resulting in the discovery of additional zones. 13,875 feet of core drilling and 25,750 feet of RC drilling was completed during the quarter. In addition to drilling at Hilltop, multiple holes are being drilled to test the Blackjack Zone and these holes are intended at testing new targets. The Ruby Hill property provides significant optionality as it is host to oxide gold, sulphide gold, polymetallic CRD and skarn base metal mineralization. All deposits are located in close proximity to the underground infrastructure development being planned in 2023.

Residual leaching activities at Ruby Hill produced and sold 1,242 ounces of gold during Q1 at a realized gold price of $1,904¹ per ounce sold.

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 Earnings / (Loss)

Adjusted earnings / (loss) and adjusted earnings / (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 earnings / (loss) nor adjusted earnings / (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 earnings / (loss) for the three months ended March 31, 2023 and 2022, to the net earnings / (loss) for each period.
