Production and sales from residual leaching at Ruby Hill and Lone Tree totaled 6,769 ounces for the quarter and 21,097 ounces year to date (YTD) at cash costs per ounce sold of $1,037¹ and $1,053¹, respectively, and all-in sustaining cost per ounce sold of $1,137¹ and $1,182¹, respectively.

Exploration, evaluation, and pre-development costs were $6.6 million in Q4 and $38.8 million YTD. This spend mainly reflects the exploration and pre-development work at Granite Creek and Ruby Hill.

Lone Tree Processing Facilities

Lone Tree is expected to become the hub of i-80's Nevada operations and the central processing facility for 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 to advance the detailed engineering study and cost estimate for the restart of the autoclave.

Residual leaching activities at Lone Tree produced 2,768 ounces gold during Q4 and 8,066 YTD at a cash cost per ounce sold of $894¹ and $936¹, respectively, and all-in sustaining cost per ounce sold of $1,067¹ and $1,174¹, respectively.

Granite Creek

The 2022 underground drill program at Granite Creek was focused on delineating mineralization for mining as well as upgrading and expanding resources expected to provide the bulk of mineralization to be mined in the following twelve months. Multiple underground levels have been developed, especially on the Ogee Zone, and the Company continued to extend the decline to depth, with the goal of initiating access to the new South Pacific Zone located immediately below and to the north of the underground mine workings. The Company targets to complete underground drilling and bring the newly discovered South Pacific Zone into the Granite Creek mine plan in 2023. In the upper parts of the mine, high-grade gold mineralization was being defined in the Otto, Adam Peak and Range Front horizons, while from the lower levels drilling was focused on defining mineralization in the Ogee Zone that is expected to be the primary zone in the near future. The amount of drilling completed as of December 31, 2022 totaling 83,887 feet was in line with the Company's drilling plan.

For the full year 2022, 17,455 tonnes of mineralized material was mined at an average grade of 7.6 g/t. The refractory material was shipped to the Twin Creeks facility for processing pursuant to the toll milling agreement that is in place with Nevada Gold Mines. The oxide material was stockpiled and has subsequently been shipped to Lone Tree for processing.

McCoy-Cove

Total development for the fourth quarter was 1,202 feet and 3,095 feet for the full year which included construction of the exploration ramp which continued on plan. Additional work on metallurgical and hydrology studies, engineering of de-watering and mining options, and reclamation activities associated with the inactive tailings storage facility is also being advanced.

Ruby Hill

During the fourth quarter, drilling of the Ruby Deeps and the Hilltop zones continued with multiple high-grade mineralization intercepts and multiple brownfield exploration targets tested, including discovery of polymetallic mineralization. 4,509 feet of core drilling and 6,875 feet of RC drilling was completed during the quarter, with a combined total of 137,210 feet completed in the year ended December 31, 2022. Due to the substantial success of the 2022 drill campaign at Ruby Hill, the program has been expanded into 2023. The primary targets of the first part of the program will be the Hilltop Corridor that includes polymetallic Carbonate Replacement Deposit (CRD) mineralization including the Upper, Lower and East Hilltop Zones, skarn mineralization in the Blackjack and Hilltop Corridor targets, and multiple untested geophysical anomalies. 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.

The Company continued to advance permitting for the construction of a decline to access the high-grade Ruby Deeps deposit and the Blackjack Zone with the intent of trucking refractory mineralization for processing at Lone Tree. The Company also completed a scoping study during the quarter for the restart of the existing oxide mill and subsequent conversion to a base metals facility.

Residual leaching activities at Ruby Hill produced 4,002 ounces gold during Q4 and 13,031 YTD at a cash cost per ounce sold of $1,135¹ and $1,126¹, respectively, and all-in sustaining cost per ounce sold of $1,185¹ and $1,187¹, respectively.

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: by-product cash cost per ounce sold, by-product all-in sustaining cost ("AISC") per ounce sold, earnings before interest, tax, depreciation and amortization, capital expenditures (expansionary), capital expenditures (sustaining), 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 significant write-down adjustments and the gain / (loss) from financing instruments.

All-in sustaining costs on a by-product basis per ounce include total production cash costs on a by-product basis and costs related to sustaining production.

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.

By-product credits include revenues from the sale of by-products from operating mines.

Capital expenditure (expansionary) is a capital expenditure intended to expand the business or operations by increasing production capacity beyond current levels of performance and includes capitalized exploration.

Capital expenditure (sustaining) is a capital expenditure necessary to maintain existing levels of production. The sustaining capital expenditures maintain the existing mine fleet, mill and other facilities so that they function at levels consistent from year to year.

Cost of sales per ounce sold is calculated by dividing the attributable cost of sales by the attributable ounces sold.

Exploration and evaluation (sustaining) expense is presented as mine site sustaining if it supports current mine operations.

Rehabilitation – accretion and amortization include depreciation on the assets related to the rehabilitation provision of gold operations and accretion on the rehabilitation provision of gold operations.

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.

Cash Costs

Cash costs per ounce sold represents all direct and indirect operating costs related to the physical activities of producing gold, including on-site mining costs, processing, third-party smelting, refining and transportation costs, on-site general and administrative costs, community site relations, royalties and royalty taxes. State of Nevada net proceeds taxes are excluded. Cash costs incorporate the Company's share of production costs but exclude, among other items, the impact of depletion, depreciation and amortization ("DD&A"), reclamation costs, inventory write-downs, financing costs, capital development and exploration and income taxes. In order to arrive at consolidated cash costs, the Company includes its attributable share of total cash costs from operations where less than 100% interest in the economic share of production is held.

Cash cost: by-product - When deriving the cash costs associated with an ounce of gold, the Company includes by-product credits, as the Company considers that the cost to produce the gold is reduced as a result of the by-product sales incidental to the gold production process. Accordingly, total production costs are reduced for revenues earned from silver sales.

Cash costs per ounce is a common financial performance measure in the mining industry, but the term does not have any standardized meaning. In determining its cash cost and cash cost per ounce, the Company has considered the guidelines provided by the World Gold Council, a non-regulatory, non-profit market development organization for the gold industry. A Company's adoption of the standard is voluntary and other companies may quantify these measures differently as a result of different underlying principles and policies applied.

All-in Sustaining Costs ("AISC")

AISC include total production cash costs incurred at the Company's mining operations, which forms the basis of the Company's by-product cash costs. Additionally, the Company includes sustaining capital expenditures which are expended to maintain existing levels of production (to which costs do not contribute to a material increase in annual gold ounce production over the next 12 months), rehabilitation accretion and amortization, and sustaining exploration and evaluation expenses. The Company does not allocate corporate general and administrative expenses. The measure seeks to reflect the full cost of production from current operations, therefore expansionary capital is excluded. Certain other cash expenditures, including tax payments (including the State of Nevada net proceeds tax), dividends and financing costs are also excluded. The Company reports AISC on a per ounce sold basis.

This financial performance measure was adopted as a result of an initiative undertaken within the gold mining industry; however, this performance measure has no standardized meaning and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. In determining AISC, the Company has considered the guidelines provided by the World Gold Council, a non-regulatory, non-profit market development organization for the gold industry. A Company's adoption of the standard is voluntary and other companies may quantify these measures differently as a result of different underlying principles and policies applied.

The following table provides a reconciliation on a by-product basis for gold cash cost and AISC for the three and twelve months ended December 31, 2022:

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 and twelve months ended December 31, 2022 and 2021, to the net earnings / (loss) for each period.
