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.

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.

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.

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.
