Second highest silver revenues in company history

COEUR D'ALENE, Idaho--(BUSINESS WIRE)-- Hecla Mining Company (NYSE:HL) today announced first quarter 2023 financial and operating results.

FIRST QUARTER HIGHLIGHTS

Operational

• Produced 4.0 million ounces of silver, a 10% increase over the fourth quarter of 2022 and more than any quarter since 2016.
• Record quarterly gold production of 14,885 ounces at Greens Creek; lead production was the 2^nd highest in Company's history.
• Greens Creek achieved record quarterly throughput of 2,591 tons per day ("tpd").
• Keno Hill development 75% complete and remains on track for third quarter mill startup.
• Achieved All-injury frequency rate (“AIFR”) of 1.13, lowest since 2012 led by Lucky Friday’s AIFR of 0.62, a safety record for the mine while at full production.

Financial

• Sales of $199.5 million with silver revenues 38% and gold revenues 35%; silver revenues were 2^nd highest in Company history.
• Consolidated silver total cost of sales of $100.8 million and cash cost and AISC per silver ounce (each after by-product credits) of $2.14 and $8.96, respectively.^3,4
• Cash flow from operations of $40.6 million, silver operations generated $89.5 million in cash flow from operations, and $68.6 million in free cash flow.²
• Net loss applicable to common stockholders of $3.3 million or $0.01 per share, and adjusted net income of $6.6 million or $0.01 per share.⁵
• Adjusted EBITDA of $61.9 million, net debt to adjusted EBITDA ratio of 1.9.¹
• Strong balance sheet with $95.9 million in cash and cash equivalents, credit facility undrawn, and $240 million in available liquidity.

Environmental, Social, Governance

• Casa Berardi received Quebec’s John T. Ryan safety award for lowest reportable injury frequency rate for the second time in three years.
• Net zero in 2022 as scope 1&2 CO₂ emissions offset with certified emission reduction credits.

Strategic

• ATAC Resources acquisition announced for CAD $31 million; transaction expected to close in the third quarter.

“As we continue our growth in silver production, silver revenues are now exceeding gold revenues for the second consecutive quarter,” said Phillips S. Baker Jr., President and CEO. “Greens Creek had excellent operational performance achieving record throughput and very strong silver and record gold production, and Lucky Friday exceeded 1.2 million ounces of silver production for third time out of the last four quarters.”

Baker continued, “Greens Creek and Lucky Friday generated $69 million in free cash flow with both mines exceeding $31 million. Our first priority in capital allocation of this free cash flow is investing it in our mines – particularly Keno Hill, which remains on track to produce more than 2.5 million ounces of silver this year, Casa Berardi, where we are beginning the transition to a primarily open pit operation, and Lucky Friday, where we are completing the ore bunker and service hoist.”

Baker concluded, “Hecla produced 45% of United States silver in 2022, making us the nation’s largest silver producer. With almost 17 million ounces of silver production expected in 2023 and potentially increasing to 20 million ounces by 2025, Hecla is expected to become Canada’s largest silver producer as well. Our production growth provides shareholders more exposure to silver from long-lived, low-cost mines that will help provide silver needed for solar power, the fastest growing renewable energy source.”

Net loss applicable to common stockholders decreased to $3.3 million in the first quarter of 2023 from $4.6 million in the fourth quarter of 2022 due to:

• Increased gross profit of $9.9 million due to higher revenues arising from higher realized metals prices (except lead) and lower cost of sales.
• Decreased general and administrative expenses of $2.3 million as a result of a higher incentive compensation accrued in the fourth quarter of 2022.
• Decreased provision for closed operations and environmental matters of $3.6 million reflecting the Troy Mine accrual recorded in the fourth quarter of 2022.
• Decreased exploration and pre-development expenses of $1.9 million reflecting lower expenditures across our portfolio.

The above items were partly offset by:

• Decreased fair value adjustments, net of $6.8 million resulting from changes in our marketable securities portfolio.
• Increased ramp-up and suspension costs of $3.8 million as a result of continued ramp-up at Keno Hill.
• Increased income and mining tax expense of $7.2 million, reflecting increased taxable income from our U.S. assets

Consolidated silver total cost of sales in the first quarter decreased by 2% to $100.8 million from the prior quarter due to lower fuel prices partially offset by higher labor costs. Cash costs and AISC per silver ounce, each after by-product credits, were $2.14 and $8.96, respectively.^3,4 The decrease in cash costs per ounce was due to higher silver production, lower total cost of sales, higher by-product credits due to higher gold and lead production, and higher gold prices, with AISC further impacted by lower sustaining capital due to timing of expenditures ^3,4

Consolidated total gold cost of sales decreased by 2% to $63.7 million primarily due to lower labor and consumables costs attributable to lower underground tonnage at Casa Berardi. Cash costs and AISC per gold ounce, each after by-product credits, were $1,775 and $2,392, respectively.^3,4 The increase in cash costs per ounce was primarily due to lower gold production resulting from lower grades, with AISC further impacted by higher sustaining capital.

Adjusted EBITDA for the quarter was $61.9 million, in line with the prior quarter as higher gross profit and lower depreciation, depletion and amortization and general and administrative expenses in the quarter were offset by the monetization of zinc hedges in the prior quarter. The ratio of net debt (calculated as long-term debt and finance leases less cash) to adjusted EBITDA was unchanged at 1.9, with long-term debt and finance leases of $526.0 million and cash and equivalents of $95.9 million at the end of the quarter.¹ The Company also issued stock under its ATM program in the first quarter for net proceeds of $11.9 million.

Cash provided by operating activities was $40.6 million, an increase of 12% over the prior quarter due to higher gross profit and favorable working capital changes partially offset by the monetization of zinc hedges in the prior quarter.

Capital expenditures, net of leases, totaled $54.4 million compared to $56.1 million in prior quarter. The decrease was due to timing related lower capital spend at Greens Creek, which was offset by higher capital spend at Casa Berardi primarily attributable to the tailings expansion, higher development, and equipment capital spend at Keno Hill as the mine prepares for mill startup in the third quarter of 2023, and higher capital spend at Lucky Friday with the service hoist and coarse ore bunker projects expected to be completed by the fourth quarter.

Free cash flow for the quarter was negative $13.8 million, compared to negative $20.0 million in the prior quarter due to higher gross profit, lower production costs, favorable working capital changes, and lower capital spending.²

Forward Sales Contracts for Base Metals and Foreign Currency

The Company uses financially settled forward sales contracts to manage exposures to zinc and lead price changes. On March 31, 2023, the Company had contracts covering approximately 29% of the forecasted payable zinc production for 2023 at an average price of $1.47 per pound, and 38% of the forecasted payable lead production (through 2025) at an average price of $0.99 per pound.

The Company also manages CAD exposure through forward contracts. On March 31, 2023, the Company had hedged approximately 47% of forecasted Casa Berardi CAD direct production costs through 2026 at an average CAD/USD rate of 1.32. The Company has also hedged approximately 21% of Casa Berardi capital costs through 2026 at 1.35. At Keno Hill, 70% of the total planned spend for 2023 and 2024 is hedged at an average CAD/USD rate of 1.36.

Greens Creek produced 2.8 million ounces of silver in the first quarter, an increase of 14% over the prior quarter due to higher throughput and grades. Gold production for the quarter was 14,885 ounces, a record in the mine's history and a 15% increase over the prior quarter. The mine achieved yet another quarterly throughput record of 2,591 tpd.

First quarter sales were $98.6 million and increased 3% over the prior quarter due to higher metal production except for zinc, which declined due to mine sequencing, and higher realized prices for silver, gold, and zinc. Total cost of sales for the quarter were $66.3 million, a decline of 5% over the prior quarter due to both lower fuel prices and fuel consumption as hydro power availability increased during the quarter, partially offset by higher labor costs. Cash costs and AISC per silver ounce, each after by-product credits, were $1.16 and $3.82 and decreased over the prior quarter due to higher silver production, lower production costs, and higher gold by-product credits (attributable to higher gold realized price and production). AISC was also favorably impacted by lower capital spend in the quarter due to timing.^3,4

Cash flow from operations was $43.3 million and decreased slightly over the prior quarter due to unfavorable working capital changes primarily related to an increase in accounts receivables. Free cash flow for the quarter was $37.1 million, an increase of 10% over the prior quarter due to the timing of capital spend.²

Lucky Friday produced 1.3 million ounces of silver, an increase of 3% over the prior quarter attributable to higher throughput.

Sales in the first quarter were $49.1 million, an increase of 8% over the prior quarter due to higher silver and lead production and higher realized prices. Total cost of sales were $34.5 million, an increase of 5% over the prior quarter due to increased sales volumes and higher labor costs, including higher profit sharing with the miners due to increased profitability. Cash costs and AISC per silver ounce, each after by-product credits, were $4.30 and $10.69 respectively and decreased over the prior quarter due to higher production and higher by-product credits. Lower sustaining capital spend for the quarter impacted AISC favorably.^3,4

Cash flow from operations was $46.1 million, higher than that of full year 2022, and an increase of $53.6 million over the prior quarter due to favorable working capital changes, which also included the receipt of $6.7 million related to a deferred silver concentrate shipment in the fourth quarter. Capital expenditures, net of leases, were $14.7 million, as the Company continues to invest in key projects including the service hoist and coarse ore bunker, increased development, and pre-production drilling to achieve the annual throughput goal of 425,000 tons in the fourth quarter of 2023. Free cash flow was $31.4 million, an increase of $52.6 million over the prior quarter primarily due to the increase in cash flow from operations.²

Casa Berardi produced 24,686 ounces of gold in the first quarter, a decrease of 20% over the prior quarter due to a 22% decline in overall gold grades primarily attributable to lower underground grades, partially offset by a 4% increase in mill recoveries. The mill continued to perform well, achieving a record quarterly throughput of 4,768 tpd.

Total cost of sales were $63.0 million, a decrease of 4% over the prior quarter primarily due to planned lower underground tonnage which resulted in lower underground labor, contractor, and consumables costs, partially offset by higher open pit tons. Cash costs and AISC per ounce, each after by-product credits, were $1,775 and $2,392, respectively, and increased over the prior quarter primarily due to lower gold production, with AISC also impacted by higher capital spend.^3,4

Cash flow from operations for the quarter was negative $0.7 million, a decrease of $10.9 million due to lower production and unfavorable working capital changes. Free cash flow for the quarter was negative $16.7 million, a decrease of $15.5 million over the prior quarter due to lower cash flow from operations and higher planned capital spend. ²

Expected gold production remains weighted towards the second half of 2023. Cash costs and AISC, each after by-product credits, per gold ounce, are also expected to trend lower in the second half of the year.

Underground grade at the mine has declined by approximately 30% since 2018 in accordance with the mine plan. Smaller stopes and higher relative development have contributed to cost increases, which have been further exacerbated by inflationary pressures over the past year. The Company remains focused on underground exploration, but the mine is beginning the transition from an underground to an open pit operation. The F160 pit acts as a bridge between mining at the underground mines and mining higher grade open pit material, which is in the permitting pipeline. The higher grade open pit ore has reserve grades approximately 70% higher than the F160 pit. The mine is undergoing a period of transition and investment over the next few years and remains a key operation in the Company's portfolio.

Keno Hill - Yukon Territory

At Keno Hill, ramp-up and development activities continued through the first quarter as the mine remains on track to commence production in the third quarter. As of the end of April, approximately 75% of the development required for production was complete. Capital spending for the first quarter was $17.1 million and included mine development, equipment purchases, and critical infrastructure projects including plant – reconfiguring the secondary crushing circuit and installing underground infrastructure. The workforce is about 290 people, in line with the plan. Ore from Flame & Moth and Bermingham deposit is being stockpiled. 2023 silver production is expected to exceed 2.5 million ounces with full throughput achieved by the end of the year.

EXPLORATION AND PRE-DEVELOPMENT

Exploration and pre-development expenses totaled $4.9 million for the first quarter of 2023. Exploration and definition drilling activities primarily focused on targets at Casa Berardi, Greens Creek, and Keno Hill. In addition to drilling activities, surface, and underground targets were advanced through ongoing 3D detailed geological modeling at San Sebastian, Republic, and all our operating properties. At San Sebastian, geophysical surveys are ongoing and are planned to begin at Republic during the second quarter.

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 long-term debt and finance leases 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, and mineral interests. Cash provided by operating activities for the Greens Creek, Lucky Friday, and Casa Berardi 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 total cost of sales, the sum of cost of sales and other direct production costs and depreciation, depletion and amortization (sometimes referred to as "total 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.

⁽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 total cost of sales and other direct production costs, expenses for reclamation at the mine sites and all site sustaining capital costs. AISC, after by-product credits, is calculated net of depreciation, depletion, and amortization and by-product credits. Prior year presentation has been adjusted to conform with current year presentation.

⁽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 total cost of goods sold, do not capture all the expenditures incurred to discover, develop and sustain silver and gold production. Management believes that AISC 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.

Other

⁽⁶⁾ Expectations for 2023 include silver, gold, lead and zinc production from Greens Creek, Lucky Friday, Keno Hill, and Casa Berardi converted using Au $1,800/oz, Ag $22/oz, Zn $1.15/lb., and Pb 0.90$/lb., CAD/USD 1.30. Numbers may be rounded.

Non-GAAP Measures
(Unaudited)

Reconciliation of Total Cost of Sales (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 total cost of sales, being the sum 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 months ended March 31, 2023 and 2022, the three and twelve months ended December 31, 2022, and the three months ended for September 30, 2022 and June 30, 2022.

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 reclamation and sustaining capital. Prior year presentation has been adjusted to conform with current year presentation. This is similar to the Cash Cost, After By-product Credits, per Ounce non-GAAP measure we report, but also includes 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 reclamation, and sustaining capital costs. AISC, Before By-product Credits for our consolidated silver properties also includes corporate costs for general and administrative expense 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.

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.

(1)		Includes all direct and indirect operating costs related to the physical activities of producing metals, including mining, processing and other plant costs, third-party refining and marketing expense, on-site general and administrative costs and royalties, before by-product revenues earned from all metals other than the primary metal produced at each operation. AISC, Before By-product Credits also includes reclamation and sustaining capital costs.
(2)		AISC, Before By-product Credits for our consolidated silver properties includes corporate costs for general and administrative expense, and sustaining capital.
(3)		During the three months ended March 31, 2023, the Company completed the necessary studies to conclude usage of the F-160 pit as a tailings storage facility after mining is complete. As a result, a portion of the mining costs have been excluded from Cash Cost, Before By-product Credits and AISC, Before By-product Credits.
(4)		Other includes $509,000 of sales and $432,000 of cost of sales for the environmental services business acquired as part of the Alexco acquisition.
(5)		Prior year presentation has been adjusted to conform with current year presentation to eliminate exploration costs from the calculation of AISC, Before By-product Credits as exploration is an activity directed at the Corporate level to find new mineral reserve and resource deposits, and therefore we believe it is inappropriate to include exploration costs in the calculation of AISC, Before By-product Credits for a specific mining operation.

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:
