Hecla Reports First Quarter 2021 Results

May 06, 2021

COEUR D'ALENE, IDAHO--(BUSINESS WIRE)--May 06, 2021--Hecla Mining Company (NYSE:HL) (Hecla or the Company) today announced first quarter 2021 financial and operating results.

HIGHLIGHTS

* Sales of $210.9 million, second highest in the 130-year history, a 54% increase over prior year. * Gross profit of $64.8 million, an increase of $53.4 million over prior year. * Cash provided by operating activities of $37.9 million and $16.5 million of quarterly free cash flow1. * Silver production of 3.5 million ounces, a 7% increase over prior year period. * Net income applicable to common shareholders of $18.8 million, or $0.04 per share (basic). * Adjusted net income applicable to common stockholders of $30.6 million, or $0.06 per share.2 * Record Adjusted EBITDA of $86.1 million; net debt/adjusted EBITDA (last 12 months) of 1.4x.4

* Strong liquidity with quarter-end cash position of $139.8 million and undrawn revolving credit facility. * Increased the silver -linked dividend at the $25 per ounce silver price threshold by 50% to $0.03 annually. Board has also increased each level of the silver-linked dividend by $0.01 per year. * Greens Creek AISC6 in the first quarter of $1.59 per silver ounce and a new estimate for the year of less than $7.25. * Ratings upgrade from Moody's with Corporate Family Rating (CFR) upgraded to B2 from B3. * Continued safe management of COVID-19 across all our operations. * Sustainability report outlining our 2020 ESG performance and exploration results to be released in conjunction with the Company's Annual Meeting of Shareholders on May 19, 2021.

"The strong performance Hecla has had in five of the last six quarters continued in the first quarter of 2021 with the second highest sales in our history, a new record for EBITDA and gross profit on sales that is about a third higher than the next closest quarter," said Phillips S. Baker, Jr., President and CEO. "Free cash flow generation was the most Hecla has had in the first quarter in a decade. Since the first quarter is typically our smallest quarter, we anticipate cash flow increasing over the rest of the year. Therefore, the Board has increased the silver-linked dividend at the $25 price threshold by 50% to $0.03 per share annually."

Mr. Baker continued, "The backdrop for silver remains very positive with improving industrial demand due to global policies that support green energy where silver is a key component, strong investment demand and tight supply. Hecla is in a key position as the United States' largest silver producer, mining more than a third of all U.S. production, which should increase as our U.S. silver production is anticipated to be 15 million ounces by 2023 with the Lucky Friday's silver production expected to increase to 5 million ounces by then."

FINANCIAL DATA (000s except per share)

Sales (000) $ 210,852 $ 136,925

Gross profit (000) $ 64,812 $ 11,372

Income (loss) applicable to common stockholders $ 18,833 $ (17,323) (000)

Basic income (loss) per common share $ 0.04 $ (0.03)

Diluted income (loss) per common share $ 0.03 $ (0.03)

Cash provided by operating activities (000) $ 37,936 $ 4,927

Income applicable to common shareholders for the first quarter was $18.8 million, or $0.04 per share, compared to a loss of $17.3 million, or ($0.03 per share), in the first quarter of 2020, and was impacted by the following factors:

* Gross profit increased by $53.4 million due primarily to higher metal prices and production of silver, lead, and zinc. Production increased due to higher grades and Lucky Friday being in full production. Profit also improved due to lower treatment charges at Greens Creek. Casa Berardi also contributed with strong gold production from higher grades, recovery, and improved throughput in the current period. * Ramp-up and suspension costs decreased by $8.7 million primarily due to Lucky Friday's return to full production in the fourth quarter of 2020. * Lower interest expense by $5.6 million due to the following items in the first quarter of 2020: (i) interest recognized on both the 7.25% Senior Notes due 2028 and since-redeemed 2021 Notes for an overlapping period, (ii) $1.7 million in unamortized initial purchaser discount on the 2021 Notes recognized as expense upon their redemption, and (iii) amounts drawn on our revolving credit facility. * Provision for closed operations and environmental matters increased by $3.2 million due to an increase at an historic site. * Exploration and pre-development expense increased by $3.6 million. In the first quarter of 2021, exploration was primarily at our San Sebastian, Casa Berardi and Nevada Operations units. * Higher other operating expense by $2.7 million due to operational improvement project costs at Casa Berardi. * A gain on metal derivatives contracts of $0.5 million compared to a gain of $7.9 million in the first quarter of 2020. * A net foreign exchange loss of $2.1 million versus a net gain of $6.6 million in the first quarter of 2020, with the variance primarily related to the impact of strengthening of the Canadian dollar relative to the U.S. dollar. * An income and mining tax provision of $4.6 million compared to an income and mining tax benefit of $1.1 million in the first quarter of 2020 due to increased income at Casa Berardi and the inclusion of $3.1 million following reclassification of the Alaska mine license tax. Cash income and mining taxes paid for the first quarter totaled $2.5 million.

Cash provided by operating activities of $37.9 million increased $33.0 million compared to the first quarter of 2020, primarily due to higher gross profit, partially offset by negative working capital changes of $29.3 million related to lower accounts payable and accrued liabilities, the timing of payment of incentive compensation related to prior-year performance and higher accounts receivable due to the timing of concentrate shipments.

Adjusted EBITDA3 of $86.1 million increased 145% compared to the first quarter of 2020, primarily due to higher sales partially offset by lower gross margins at Nevada and San Sebastian. Adjusted EBITDA is $12 million more than any quarter in Hecla's history.

Capital expenditures totaled $24.7 million compared to $20.0 million in the first quarter of 2020, with the increase primarily due to spending at Lucky Friday and Casa Berardi. Capital expenditures during the first quarter of 2021 at Casa Berardi, Greens Creek, Lucky Friday, and Nevada operations were $13.8 million, $4.9 million, $5.9 million, and $0.1 million, respectively.

Greens Creek Mine - Alaska

Greens Creek continued its strong performance with slightly lower silver grades due to normal variations in the ore body and produced 2.6 million ounces of silver and 13,266 ounces of gold compared to 2.8 million ounces of silver and 12,273 ounces of gold in the first quarter of 2020. The decrease in silver production was primarily due to lower grade, with the increase in gold production resulting from higher grade, as planned. Compared to 2020, cost per ounce decreased primarily due to $5.7 million in lower treatment costs as a result of favorable smelter terms, of which $4 million are nonrecurring, and the reclassification of the Alaska mine license tax to income and mining tax provision effective January 1, 2021. With higher by-product prices, the cash cost5 and AISC6, after by-product credits, per silver ounce decreased by $6.30 and $6.31 per ounce, respectively. The mill operated at an average of 2,156 tons per day (tpd) in the first quarter compared to 2,185 tpd in the first quarter of 2020.

The Company reaffirms estimated 2021 silver production of 9.5 - 10.2 million ounces of silver and 40 - 43 thousand ounces of gold. The estimate for 2021 cost of sales is $213 million. Estimated cash cost, after by-product credits5, and AISC, after by-product credits6, each per silver ounce is $1.50-$2.25 and $6.50-$7.25, respectively, with lower costs due to anticipated higher by-product credits, lower treatment charges, and the reclassification of mine license tax from production costs to income and mining tax provision effective January 1, 2021.

Casa Berardi Mine - Quebec

At the Casa Berardi Mine, 36,190 ounces of gold were produced compared to 26,752 ounces in the first quarter of 2020. This represents an increase of 35% due to higher tonnage, grades and recoveries. The mill operated at an average of 4,093 tpd in the first quarter of 2021 compared to 3,644 tpd in 2020. The increase in cost of sales was primarily due to higher sales volume. The decrease in cash cost and AISC, after by-product credits5,6, per gold ounce for the first quarter of 2021 compared to the first quarter of 2020 was primarily the result of higher gold production, with AISC also impacted by lower sustaining capital spending, partially offset by higher exploration spending.

Business improvement activities continued in 2021 and these efforts are expected to reduce costs and increase cash flow over the next two years.

Lucky Friday Mine - Idaho

At the Lucky Friday Mine, 0.9 million ounces of silver were produced in the first quarter of 2021. Lucky Friday returned to full production in the fourth quarter of 2020 with estimated annual production in excess of 3.4 million ounces of silver in 2021. The mill operated at an average of 901 tpd. We continue to test and optimize the new mining method to improve safety and increase productivity which could allow Lucky Friday to increase production beyond the 5 million ounces expected by 2023 due to grade.

The cost of sales for the first quarter was $22.8 million, and the cash cost, after by-product credits, per silver ounce5 was $7.62. AISC6, after by-product credits, was $14.24 per silver ounce.

Nevada Operations

At the Nevada operations, 2,548 ounces of gold were produced from 16,459 tons of a stockpiled bulk sample of refractory material processed at a third-party facility. Cost of sales for the first quarter were $7.5 million and cash cost5 and AISC6, after by-product credits, per gold ounce was $1,416 and $1,461, respectively in the first quarter of 2021. The increase over the prior year period was the result of the lower gold production.

In the second quarter of 2021, the Company expects to process oxide material through the Midas mill. Over the remainder of the year, 22,000 tons of refractory material are expected to be processed in third-party facilities, roughly 12,000 tons in a roaster and 10,000 tons in an autoclave. Production for the remainder of the year is expected to be in the range of 17,000 to 19,000 ounces of gold. Fire Creek and the Midas mill are expected to be on care and maintenance by the end of the second quarter. Activities will be limited primarily to development at Hollister for Hatter Graben and exploration at Midas.

PRE-DEVELOPMENT

Pre-development spending was $0.7 million for the quarter, principally in connection with permitting of Rock Creek and Montanore. The Federal District Court's recent ruling set aside the U.S. Forest Service's 2018 Record of Decision and the U.S. Fish & Wildlife Service's 2019 Supplement to the Biological Opinion for the evaluation phase of the Rock Creek project. While we await action by the Federal agencies on possible appeal of this decision, the Company will reconsider its evaluation plan for the Rock Creek project and continue to advance the Montanore evaluation project.

At Hollister, development of the decline to allow drilling of the Hatter Graben has commenced. The pre-development cost in 2021 is expected to be about $4 million.

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 generally accepted accounting principles in the United States (GAAP). These measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP.

(1) Free cash flow is a non-GAAP measure calculated as cash provided by operating activities less additions to properties, plants and equipment.

(2) 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.

(3) Adjusted EBITDA is a non-GAAP measurement, a reconciliation of which to net income (loss), 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 (loss), 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.

(4) Net debt to adjusted EBITDA is a non-GAAP measurement, a reconciliation of adjusted EBITDA and net debt to the closest GAAP measurements of net income (loss) and debt 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.

(5) Cash cost, after by-product credits, per silver or 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 cash cost, after by-product credits, per silver ounce on an aggregate basis - aggregating the Greens Creek, Lucky Friday and San Sebastian mines - to compare performance with that of other primary silver mining companies. Gold, lead and zinc produced have been treated as by-product credits in calculating silver costs per ounce. With regard to Casa Berardi and Nevada Operations, management uses cash cost, after by-product credits, per gold ounce to compare its performance with other gold mines with a by-product credit recognized for the value of their silver 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.

(6) 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 mine 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.

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 AISC is a non-GAAP measure that provides additional information to management, investors and analysts to help in the understanding of the economics of our operations and performance compared to other producers and in the investor's visibility 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.

(1) Cash cost, after by-product credits, per ounce and AISC, after by-products credits, per ounce represent a non-U.S. Generally Accepted Accounting Principles (GAAP) measurement. A reconciliation of cash cost, after by-product credits and AISC, after by-products credits to cost of sales and other direct production costs and depreciation, depletion and amortization (GAAP) can be found in the cash cost per ounce reconciliation section of this news release. Gold, lead and zinc produced have been treated as by-product credits in calculating silver costs per ounce. The primary metal produced at Casa Berardi and Nevada Operations is gold, with a by-product credit for the value of silver production.

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 Costs, Before By-product Credits and All-In Sustaining Costs, 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 Cash Cost, Before By-product Credits, Cash Cost, After By-product Credits, AISC, Before By-product Credits and AISC, After By-product Credits for our operations at the Greens Creek, Lucky Friday, San Sebastian, Casa Berardi and Nevada Operations units for the three-month periods ended March 31, 2021 and 2020.

Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce are measures developed by precious metals companies (including the Silver Institute and the World Gold Council) 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. AISC, After By-product Credits, per Ounce is an important operating statistic that we utilize as a measures of our mines' net cash flow after costs for exploration, pre-development, reclamation, and sustaining capital. 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 mines versus those of our competitors. As a silver and gold mining company, we also use these statistics on an aggregate basis - aggregating the Greens Creek, Lucky Friday and San Sebastian mines - to compare our performance with that of other silver mining companies, and aggregating Casa Berardi and Nevada Operations for comparison to other 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, and royalties. AISC, Before By-product Credits for each mine 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, reclamation, exploration, and pre-development. By-product credits include revenues earned from all metals other than the primary metal produced at each unit. 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. 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. 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 our reporting of these non-GAAP measures are the same as those reported by other mining companies.

The Casa Berardi, Nevada Operations and combined gold properties information below reports Cash Cost, After By-product Credits, per Gold Ounce and AISC, After By-product Credits, per Gold Ounce for the production of gold, its 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 units 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 our Casa Berardi and Nevada Operations units 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, Lucky Friday and San Sebastian, our combined silver properties. Similarly, the silver produced at our other three units is not included as a by-product credit when calculating the gold metrics for Casa Berardi and Nevada Operations.

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 tax provision (benefit), depreciation, depletion, and amortization expense, acquisition costs,, foreign exchange gains and losses, unrealized gains and losses on derivative contracts, suspension-related costs, provisional price gains and losses, stock-based compensation, unrealized gains and losses on investments, provisions for closed operations, and interest and other income (expense). Net debt is calculated as total debt, which consists of the liability balances for our Senior Notes and 2021 Notes and capital leases, 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) income and debt to Adjusted EBITDA and net debt:
