Hecla Reports Fourth Quarter and Full-Year 2022 Results

10% silver production growth in 2022; Expect 18% growth in 2023 and 35% by 2025; Silver cost guidance achieved with 2023 set at similar levels

Hecla Mining Company (NYSE:HL) today announced fourth quarter and full-year 2022 financial and operating results.

ANNUAL HIGHLIGHTS

Strategic

• Completed the acquisition of Alexco Resource Corp., adding nearly 50 million ounces of silver reserves; highest-grade and largest primary silver reserves in Canada.

Operational

• Record silver reserves of 241 million ounces, gold reserves of 2.6 million ounces.
• Produced 14.2 million ounces of silver, Hecla's second highest, and 175,807 ounces of gold.
• Record lead production of 49 thousand tons and zinc production of 65 thousand tons.
• Achieved silver cost guidance with total silver cost of sales of $349.3 million and all-in sustaining cost after by-product credits ("AISC") of $11.25 per silver ounce.⁴
• Increased Lucky Friday silver production by 24% to 4.4 million ounces using the Underhand Closed Bench (UCB) mining method.
• Achieved record mill throughput milestones at all three operations.

Financial

• Reported sales of $718.9 million with almost 70% from Greens Creek and Lucky Friday.
• Net loss applicable to common stockholders of $37.9 million or $0.07 per share, and adjusted net income of $27.8 million or $0.05 per share.⁵
• Adjusted EBITDA of $217.5 million, net debt to adjusted EBITDA ratio of 1.9.¹
• Strong balance sheet with $104.7 million in cash and cash equivalents with approximately $245 million in available liquidity.
• Dividends of $12.9 million, or 14% of cash flow from operations.

Environmental, Social, Governance

• Strong safety performance with an All-Injury Frequency Rate of 1.22, which equals prior Company record and is 42% below the U.S. average.
• The San Sebastian mine received the 2022 Environmental and Sustainability Excellence Award given by AEMA.
• Lucky Friday received the SME Murray Innovation Award for 2023 for the pioneering UCB mining method.
• Ratified a 6-year contract agreement with the Union at the Lucky Friday.

"Hecla is the world's fastest growing established silver company," said Phillips S. Baker Jr., President and CEO. "This growth has been built on the strong foundation of Greens Creek, the United States' largest silver mine, and the Lucky Friday, a mine in production for 80 years whose throughput this year was the most in its history. Added to these growing mines is Keno Hill, one of the world's highest grade silver mines, which we expect to be in production in the second half of this year."

Baker continued, "In 2022, we achieved our largest silver reserves and second highest silver production in our history, and expect to set new records in 2023 and 2024. If our growth continues as expected, Hecla would produce not only 40% of all the silver mined in the US, but also 40% of all silver mined in Canada. In 2022, we had among the best silver margins in the industry with AISC a little more than half of our realized silver price allowing us to maintain a strong balance sheet even after significant investment in the Lucky Friday and Keno Hill. We expect silver AISC in 2023 to be about the same as 2022 despite inflationary pressures and increased investment in all our mines. With our largest silver reserves, our growing production in Canada and the US, and strong silver margins, we believe our shareholders are well-positioned for higher silver prices as the transition to renewables increases the need for silver as an energy metal."

Loss applicable to common stockholders decreased to $4.6 million in the fourth quarter 2022 from $23.7 million in the third quarter due to:

• Increased gross profit of $16.6 million due to higher revenues arising from deferred silver concentrate shipments from Greens Creek and Lucky Friday to the fourth quarter, higher realized prices and production partially offset by higher cost of sales.
• Exploration and pre-development expense decreased by $8.2 million due to the completion of seasonal exploration programs in the prior quarter.

The above items were partially offset by:

• Increase in general and administrative expenses of $3.4 million due to higher incentive compensation accruals and a full quarter of additional staffing as a result of the Alexco acquisition.
• Increase of $2.9 million in provision for closed operations reflecting updated costs for Troy mine reclamation.
• Higher ramp-up and suspension costs of $2.5 million related to the Keno Hill ramp-up.

Consolidated silver cost of sales in 2022 increased 12% to $349.3 million from the prior year due to higher labor costs including contractor costs, and inflationary pressures for fuel, consumables, ground support and other inputs. Cash costs and AISC per silver ounce, each after by-product credits, were $2.06 and $11.25, respectively.^3,4 The increase in cash costs and AISC per silver ounce was due to higher cost of sales, and increased sustaining capital, partially offset by higher by-product credits due to higher by-products and silver production.^3,4

Consolidated gold cost of sales decreased by 9% to $253.0 million primarily due to Nevada operations were being on care and maintenance. Cash costs and AISC per gold ounce, each after by-product credits, were $1,478 and $1,825, respectively.^3,4 The increase in total cash costs was due to higher labor, contractor costs, and inflation in diesel, reagents, and other key inputs as well as lower gold production with AISC also impacted by higher sustaining capital.

Loss applicable to common stockholders was $37.9 million in 2022 compared to net income of $34.5 million in 2021 with decrease in profitability attributable to:

• Lower sales of $88.6 million due to lower gold production and lower metal prices for silver, lead, and zinc, partially offset by higher silver, lead and zinc production.
• Lower gross profit due to lower sales and higher production costs.
• Higher general and administrative expenses of $8.8 million due to higher incentive compensation accruals, compensation increases effective July 1, and additional staffing as a result of the Alexco acquisition.
• A decrease in income tax benefit of $22.0 million

The above items were partially offset by:

• Decrease in exploration and pre-development expense of $1.9 million.
• Fair value adjustments that resulted in a loss of $4.7 million in 2022 compared to a loss of $35.8 million in 2021 as result of lower realized and unrealized losses on derivatives and investments.
• Decrease in provision for closed operations and environmental matters of $5.8 million.

Adjusted EBITDA for the year was $217.5 million and decreased by $61.3 million over the prior year primarily due to lower revenues and higher production costs amidst inflationary pressures. The ratio of Net debt to adjusted EBITDA increased to 1.9 due to lower Adjusted EBITDA and use of cash as the Company invested in development of the Keno Hill mine.¹

Cash provided by operating activities was $89.9 million for 2022 and decreased $130.5 million year over year due to lower net income and unfavorable working capital changes. When compared to the third quarter, cash provided by operating activities increased by $60.4 million due to increased gross margin and monetization of zinc hedges.

Capital expenditures, net of leases, totaled $149.4 million in 2022 compared to $109.0 million in 2021. The increase was due to higher capital spend at Lucky Friday, as the Company invested in the infrastructure necessary to increase throughput, sustaining expenditures at Greens Creek, and development capital at the Keno Hill partially offset by lower spend at Casa Berardi. Fourth quarter capital expenditures totaled $56.1 million, including $12.2 million at Greens Creek, $13.0 million at Casa Berardi, $13.7 million at Lucky Friday, and $16.1 million at Keno Hill.

Free cash flow for the year was negative $59.5 million, a decrease of $170.8 million over the prior year due to lower revenues, higher production costs, higher capital spend at Lucky Friday and Greens Creek, and investment in the Keno Hill development. Free cash flow for the fourth quarter was negative $20.0 million and increased by $41.7 million over the prior quarter primarily due to higher cash flow from operations partially offset by higher capital spend.²

Forward Sales Contracts for Base Metals and Foreign Currency

The Company uses financially settled forward sales contracts to manage exposures to changes in prices of zinc and lead. At December 31, 2022, the Company had contracts covering approximately 36% of the forecasted payable zinc production for 2023 at an average price of $1.34 per pound, and 40% of the forecasted payable lead production (through 2024) at an average price of $0.99 per pound. In the fourth quarter, the Company monetized zinc hedges for cash proceeds of approximately $17.0 million.

The Company also manages CAD exposure through forward contracts. At December 31, 2022, the Company had hedged approximately 46% of forecasted CAD direct production costs for Casa Berardi through 2026 at an average CAD/USD rate of 1.31. The Company has also hedged approximately 34% of capital costs for Casa Berardi for 2023 at 1.33. At Keno Hill, 74% of the planned spend for 2023 is hedged at an average CAD/USD rate of 1.38.

Greens Creek produced 9.7 million ounces of silver in 2022, an increase of 5% over the prior year achieving record mill throughput.

Fourth quarter sales were $95.4 million, and increased $34.5 million over the third quarter due to higher realized prices, increased by-product production and the favorable impact of a deferred silver concentrate shipment from the third quarter resulting in higher metals sold. Cost of sales for the quarter were $70.1 million, an increase of $17.6 million over the prior quarter with the increase attributable to higher costs related to higher volumes of metals sold and higher fuel and consumables costs. Cash costs and AISC per silver ounce, each after by-product credits, were $4.26 and $9.04 and increased quarter over quarter due to higher treatment and freight costs due to higher concentrate quantities shipped, and higher costs related to fuel and consumables as the mill achieved record throughput.^3,4 Cash flow from operations increased by $37.0 million over the prior quarter due to increased sales and lower exploration spend partially offset by higher costs. Free cash flow for the fourth quarter was $33.7 million, an increase of $29.1 million over the prior quarter due to higher cash flow from operations partially offset by higher capital spend.²

2022 sales were $335.1 million, a decrease of $49.8 million compared to 2021 due to lower realized silver prices partially offset by higher silver and gold production. Cost of sales increased to $232.7 million compared to $213.1 million in 2021 due to higher labor and contractor costs due to record tons mined, inflationary pressures for fuel, reagents and other inputs, and higher volumes of consumables as the mill achieved record throughput in 2022. Cash costs and AISC per silver ounce (each after by-product credits) were $0.70 and $5.77, respectively, increasing year over year due to the reasons outlined above, partially offset by higher by-product credits.^3,4 The increase in AISC was also impacted by higher exploration and sustaining capital spend during the year. Cash flow from operations for the year was $150.6 million, and decreased by $58.1 million over the prior year due to lower revenues and higher production costs. Free cash flow generation for the year was $119.6 million and declined by $69.8 million over the prior year due to lower cash flow from operations and higher planned capital spend.²

Lucky Friday produced 4.4 million ounces of silver, an increase of 24% over the prior year due to record throughput, and higher mined grades. Silver production for the fourth quarter was 1.2 million ounces, an increase of 14% over the prior quarter due to higher grades mined.

Fourth quarter sales were $45.4 million, an increase of $17.0 million over the prior quarter due to increased production, higher realized prices, and the sale of the silver concentrate shipment which was deferred from the third quarter. Cost of sales were $32.8 million and increased $8.7 million over the prior quarter due to costs associated with the deferred silver concentrate shipment inventoried in the third quarter, and higher labor costs as the mine continued to fill key positions. Cash costs after by-product credits per silver ounce were $5.81 and increased over the prior quarter due to higher labor costs and higher treatment and freight costs resulting from higher concentrate sales, partially offset by higher by-product credits and higher silver production. AISC after by-product credits per silver ounce was $12.88 and decreased over the prior quarter as the factors affecting cash cost per ounce were offset by lower capital spend in the fourth quarter.^3,4 Cash flow from operations was negative $7.4 million, a decrease of $19.1 million over the prior quarter due to unfavorable working capital changes and receipt of $6.7 million related to the deferred silver concentrate shipment received in January 2023. Free cash flow was negative $21.2 million and decreased over the prior quarter primarily due to decreased cash flow from operations partially offset by lower capital spend.²

2022 sales were $147.8 million, an increase of $16.3 million over 2021 as higher metal production offset lower realized prices and higher treatment costs due to increased concentrate production. Cost of sales increased to $116.6 million compared to $97.5 million in 2021 reflecting higher costs related to increased tons mined and milled, as well as inflationary pressures for fuel, reagents and other input costs realized during the year. Cash costs and AISC per silver ounce, each after by-product credits, were $5.06 and $12.86, respectively, decreasing year over year due to higher production and by-product credits partially offset by higher costs and capital spend. ^3,4 Cash flow from operations for the year was $37.8 million, a decrease of $24.8 million over the prior year due to higher production costs and unfavorable working capital changes. Free cash flow was negative $13.2 million due to lower cash flow from operations and increased capital spend for the year.²

Casa Berardi produced 127,590 and 30,709 ounces of gold in 2022 and the fourth quarter, respectively. Gold production for the year decreased by 5% compared to last year due to a 12% decrease in overall gold grade, partially offset by a 4% increase in tonnage and a 3% increase in mill recoveries. The lower grade was due to a higher ratio of lower grade ore sourced from the open pits. The mill continued to perform well, achieving record throughput of 4,468 tons per day (tpd) in the fourth quarter of 2022.

Full year 2022 cost of sales was $248.9 million, an increase of $19.1 million over the prior year due to inflationary pressures and increased labor, consumables, and contractor costs. Cash costs and AISC per ounce, each after by-product credits, were $1,478 and $1,825, respectively.^3,4 The year over year increase in cash costs and AISC per gold ounce was due to higher production costs and lower gold production in 2022, and AISC per ounce was also impacted by higher sustaining capital and higher exploration spending.^3,4

Cash flow from operations for the year was $34.4 million and decreased year over year due a combination of lower production and higher operating costs. Free cash flow for the year was $3.0 million compared to $33.7 million in 2021.²

Keno Hill - Yukon Territory

At Keno Hill, production is expected to commence in the third quarter 2023 with a phased ramp up projected to reach 440 tpd by the end of the year. Anticipated silver production for the year is 2.5-3 million ounces expected from the Bermingham and Flame & Moth deposits. As of the end of January 2023, approximately 40% of development required to achieve full production was completed. Capital spending to bring the mine to full production is estimated to be $35-$40 million in 2023. Some key capital projects underway include camp expansion, mill improvements and engineering, and other surface capital infrastructure projects.

EXPLORATION AND PRE-DEVELOPMENT

Exploration and pre-development expenses totaled $6.9 million for the fourth quarter and $46.0 million for the full year. Exploration activities during the fourth quarter focused on targets at Keno Hill, Casa Berardi, and Greens Creek.

For the year ended 2022, the Company reported the highest silver reserves of more than 240 million ounces, an increase of 21% over 2021. The increase was primarily due to the acquisition of Keno Hill in Canada's Yukon territory. Gold reserves declined 6% to 2.6 million ounces compared to 2021 due to cost increases which increased the cut-off grade at Casa Berardi. A breakdown of the Company's reserves and resources is located in Table A at the end of this news release.

For further details on Company's 2022 exploration and pre-development program and 2023 planned expenditures as well as reserves and resources at year-end 2022, please refer to the news release entitled "Hecla Reports Highest Silver Reserves in Company History" released on February 14, 2023.

2023 ESTIMATES⁶

The Company is providing a three-year production outlook and 2023 estimates of costs, capital and exploration and pre-development expenses.

2023 - 2025 Production Outlook

Production guidance for 2023-2025 includes expected production from Keno Hill. Consolidated silver production is expected to increase over the three years to reach 18.5-20 million ounces by 2025. Consolidated gold production is expected to decrease to 160-170 thousand ounces in 2023 primarily due to Casa Berardi as an increase in the underground cut-off grade will lower gold production and reduce lower margin material and lower contractor costs.

Casa Berardi's production is expected to be lower in the first half of 2023 and increase in the latter half of the year. Cash costs and AISC, each after by-product credits, per gold ounce are expected to be higher in the first half and trend lower in the second half of the year.

NOTES

Non-GAAP Financial Measures

Non-GAAP financial measures are intended to provide additional information only and do not have any standard meaning prescribed by United States generally accepted accounting principles (GAAP). These measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The non-GAAP financial measures cited in this release and listed below are reconciled to their most comparable GAAP measure at the end of this release.

⁽¹⁾ Adjusted EBITDA is a non-GAAP measurement, a reconciliation of which to net income, the most comparable GAAP measure, can be found at the end of the release. Adjusted EBITDA is a measure used by management to evaluate the Company's operating performance but should not be considered an alternative to net income, or cash provided by operating activities as those terms are defined by GAAP, and does not necessarily indicate whether cash flows will be sufficient to fund cash needs. In addition, the Company may use it when formulating performance goals and targets under its incentive program. Net debt to adjusted EBITDA is a non-GAAP measurement, a reconciliation of which to debt and net income (loss), the most comparable GAAP measurements, can be found at the end of the release. It is an important measure for management to measure relative indebtedness and the ability to service the debt relative to its peers. It is calculated as total debt outstanding less total cash on hand divided by adjusted EBITDA.

⁽²⁾ Free cash flow is a non-GAAP measure calculated as cash provided by operating activities less additions to properties, plants and equipment. Cash provided by operating activities for the Greens Creek, Lucky Friday, Casa Berardi, and Nevada operating segments excludes exploration and pre-development expense, as it is a discretionary expenditure and not a component of the mines' operating performance.

⁽³⁾ Cash cost, after by-product credits, per silver and gold ounce is a non-GAAP measurement, a reconciliation of which to cost of sales and other direct production costs and depreciation, depletion and amortization (sometimes referred to as "cost of sales" in this release), can be found at the end of the release. It is an important operating statistic that management utilizes to measure each mine's operating performance. It also allows the benchmarking of performance of each mine versus those of our competitors. As a primary silver mining company, management also uses the statistic on an aggregate basis - aggregating the Greens Creek and Lucky Friday mines - to compare performance with that of other silver mining companies, and aggregating Casa Berardi and the Nevada operations, to compare its performance with other gold mining companies. Similarly, the statistic is useful in identifying acquisition and investment opportunities as it provides a common tool for measuring the financial performance of other mines with varying geologic, metallurgical and operating characteristics. In addition, the Company may use it when formulating performance goals and targets under its incentive program. Cash cost, after by-product credits, per silver ounce is not presented for Lucky Friday for the first nine-months of 2020, as production was limited due to the strike and subsequent ramp-up and results are not comparable to those from prior periods and are not indicative of future operating results under full production.

⁽⁴⁾ All-in sustaining cost (AISC), after by-product credits, is a non-GAAP measurement, a reconciliation of which to cost of sales and other direct production costs and depreciation, depletion and amortization, the closest GAAP measurement, can be found in the end of the release. AISC, after by-product credits, includes cost of sales and other direct production costs, expenses for reclamation and exploration at the mines sites, corporate exploration related to sustaining operations, and all site sustaining capital costs. AISC, after by-product credits, is calculated net of depreciation, depletion, and amortization and by-product credits.

⁽⁵⁾ Adjusted net income (loss) applicable to common stockholders is a non-GAAP measurement, a reconciliation of which to net income (loss) applicable to common stockholders, the most comparable GAAP measure, can be found at the end of the release. Adjusted net income (loss) is a measure used by management to evaluate the Company's operating performance but should not be considered an alternative to net income (loss) as defined by GAAP. They exclude certain impacts which are of a nature which we believe are not reflective of our underlying performance. Management believes that adjusted net income (loss) per common share provides investors with the ability to better evaluate our underlying operating performance.

Current GAAP measures used in the mining industry, such as cost of goods sold, do not capture all the expenditures incurred to discover, develop and sustain silver and gold production. Management believes that all-in sustaining costs is a non-GAAP measure that provides additional information to management, investors and analysts to help (i) in the understanding of the economics of our operations and performance compared to other producers and (ii) in the transparency by better defining the total costs associated with production. Similarly, the statistic is useful in identifying acquisition and investment opportunities as it provides a common tool for measuring the financial performance of other mines with varying geologic, metallurgical and operating characteristics. In addition, the Company may use it when formulating performance goals and targets under its incentive program.

Non-GAAP Measures
(Unaudited)

Reconciliation of Cost of Sales and Other Direct Production Costs and Depreciation, Depletion and Amortization (GAAP) to Cash Cost, Before By-product Credits and Cash Cost, After By-product Credits (non-GAAP) and All-In Sustaining Cost, Before By-product Credits and All-In Sustaining Cost, After By-product Credits (non-GAAP)

The tables below present reconciliations between the most comparable GAAP measure of cost of sales and other direct production costs and depreciation, depletion and amortization to the non-GAAP measures of (i) Cash Cost, Before By-product Credits, (ii) Cash Cost, After By-product Credits, (iii) AISC, Before By-product Credits and (iv) AISC, After By-product Credits for our operations at Greens Creek, Lucky Friday, Casa Berardi and Nevada Operations and for the Company for the three- and twelve-month periods ended December 31, 2022 and 2021, and for estimated amounts for the twelve months ended December 31, 2023.

Cash Cost, After By-product Credits, per Ounce is a measure developed by precious metals companies (including the Silver Institute) in an effort to provide a uniform standard for comparison purposes. There can be no assurance, however, that these non-GAAP measures as we report them are the same as those reported by other mining companies.

Cash Cost, After By-product Credits, per Ounce is an important operating statistic that we utilize to measure each mine's operating performance. We have recently started reporting AISC, After By-product Credits, per Ounce which we use as a measure of our operation's net cash flow after costs for exploration, pre-development, reclamation, and sustaining capital. This is similar to the Cash Cost, After By-product Credits, per Ounce non-GAAP measure we report, but also includes on-site exploration, reclamation, and sustaining capital costs. Current GAAP measures used in the mining industry, such as cost of goods sold, do not capture all the expenditures incurred to discover, develop and sustain silver and gold production. Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce also allow us to benchmark the performance of each of our operations versus those of our competitors. As a primary silver and gold mining company, we also use these statistics on an aggregate basis. We aggregate Greens Creek and Lucky Friday to compare our performance with that of other primary silver mining companies and aggregate Casa Berardi and Nevada Operations to compare our performance with that of other primary gold mining companies. Similarly, these statistics are useful in identifying acquisition and investment opportunities as they provide a common tool for measuring the financial performance of other mines with varying geologic, metallurgical and operating characteristics.

Cash Cost, Before By-product Credits and AISC, Before By-product Credits include all direct and indirect operating cash costs related directly to the physical activities of producing metals, including mining, processing and other plant costs, third-party refining expense, on-site general and administrative costs, royalties and mining production taxes. AISC, Before By-product Credits for each operation also includes on-site exploration, reclamation, and sustaining capital costs. AISC, Before By-product Credits for our consolidated silver properties also includes corporate costs for general and administrative expense, exploration and sustaining capital projects. By-product credits include revenues earned from all metals other than the primary metal produced at each operation. As depicted in the tables below, by-product credits comprise an essential element of our silver unit cost structure, distinguishing our silver operations due to the polymetallic nature of their orebodies.

In addition to the uses described above, Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce provide management and investors an indication of operating cash flow, after consideration of the average price, received from production. We also use these measurements for the comparative monitoring of performance of our mining operations period-to-period from a cash flow perspective. However, comparability of Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce for 2022 to 2021 is impacted by, among other factors, (i) the return to full production at Lucky Friday in the fourth quarter of 2020 and (ii) suspension of production at San Sebastian in the fourth quarter of 2020 and discontinuation of San Sebastian being reported as an operating segment in 2021.

The Casa Berardi and Nevada Operations sections below report Cash Cost, After By-product Credits, per Gold Ounce and AISC, After By-product Credits, per Gold Ounce for the production of gold, their primary product, and by-product revenues earned from silver, which is a by-product at Casa Berardi and Nevada Operations. Only costs and ounces produced relating to operations with the same primary product are combined to represent Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce. Thus, the gold produced at Casa Berardi and Nevada Operations is not included as a by-product credit when calculating Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce for the total of Greens Creek and Lucky Friday, our combined silver properties. Similarly, the silver produced at our other two operations is not included as a by-product credit when calculating the similar gold metrics for Casa Berardi.

Reconciliation of Net Income (Loss) (GAAP) and Debt (GAAP) to Adjusted EBITDA (non-GAAP) and Net Debt (non-GAAP)

This release refers to the non-GAAP measures of adjusted earnings before interest, taxes, depreciation and amortization ("Adjusted EBITDA"), which is a measure of our operating performance, and net debt to adjusted EBITDA for the last 12 months (or "LTM adjusted EBITDA"), which is a measure of our ability to service our debt. Adjusted EBITDA is calculated as net income (loss) before the following items: interest expense, income and mining taxes, depreciation, depletion, and amortization expense, ramp-up and suspension costs, gains and losses on disposition of properties, plants, equipment and mineral interests, foreign exchange gains and losses, unrealized gains and losses on derivative contracts, interest and other income, unrealized gains on investments, provisions for environmental matters, stock-based compensation, provisional price gains and losses, the grant of common shares to the Hecla Charitable Foundation, adjustments of inventory to net realizable value. Net debt is calculated as total debt, which consists of the liability balances for our Senior Notes, capital leases, and other notes payable, less the total of our cash and cash equivalents and short-term investments. Management believes that, when presented in conjunction with comparable GAAP measures, adjusted EBITDA and net debt to LTM adjusted EBITDA are useful to investors in evaluating our operating performance and ability to meet our debt obligations. The following table reconciles net loss and debt to adjusted EBITDA and net debt:

Reconciliation of Net (Loss) Income Applicable to Common Stockholders (GAAP) to Adjusted Net (Loss) Income Applicable to Common Shareholders (non-GAAP)

This release refers to a non-GAAP measure of adjusted net income (loss) applicable to common stockholders and adjusted net income (loss) per share, which are indicators of our performance. They exclude certain impacts which are of a nature which we believe are not reflective of our underlying performance. Management believes that adjusted net income (loss) per common share provides investors with the ability to better evaluate our underlying operating performance.

(1) The term "reserve" means an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. The term "proven reserves" means the economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource. See footnotes 8 and 9 below.
(2) Mineral reserves are based on $17/oz silver, $1600/oz gold, $0.90/lb lead, $1.15/lb zinc, unless otherwise stated. All Mineral Reserves are reported in-situ with estimates of mining dilution and mining loss.
(3) The reserve NSR cut-off values for Greens Creek are $210/ton for all zones except the Gallagher Zone at $215/ton; metallurgical recoveries (actual 2022): 81% for silver, 72% for gold, 82% for lead, and 89% for zinc.
(4) The reserve NSR cut-off values for Lucky Friday are $241.34/ton for the 30 Vein and $268.67/ton for the Intermediate Veins; metallurgical recoveries (actual 2022): 95% for silver, 95% for lead, and 88% for zinc.
(5) The average reserve cut-off grades at Casa Berardi are 0.12 oz/ton gold underground and 0.04 oz/ton gold for open pit. Metallurgical recovery (actual 2022): 87% for gold; US$/CAN$ exchange rate: 1:1.3.
(6) The reserve NSR cut-off value at Keno Hill is $244.24/ton (CAN$350/tonne), Metallurgical recovery: 93% for silver, 25% for gold, 93% for lead, 72% for zinc; US$/CAN$ exchange rate: 1:1.3.
(7) The term "probable reserves" means the economically mineable part of an indicated and, in some cases, a measured mineral resource. See footnotes 9 and 10 below.

Totals may not represent the sum of parts due to rounding.

Note: All estimates are in-situ except for the proven reserves at Greens Creek which are in surface stockpiles. Mineral resources are exclusive of reserves.

(8) The term "mineral resources" means a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled.

(9) The term "measured resources" means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.

(10) The term "indicated resources" means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve.

(11) The term "inferred resources" means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve.

(12) Mineral resources are based on $1700/oz gold, $21/oz silver, $1.15/lb lead, $1.35/lb zinc and $3.00/lb copper, unless otherwise stated.
