Hecla Reports Second Quarter 2019 Results

Hecla Mining Company (NYSE:HL) today announced second quarter 2019 financial and operating results.

HIGHLIGHTS

• Silver production of 3.0 million ounces and gold production of 60,768 ounces.
• Increasing annual silver production estimate Company-wide to 11.7 million ounces due to higher grades at Greens Creek.
• Total annual gold production estimate Company-wide unchanged at 274,000 ounces.
• Sales of $134.2 million.
• Adjusted net loss applicable to common shareholders of $36.4 million, or $0.07 per share.¹
• Adjusted EBITDA of $22.9 million and net debt/adjusted EBITDA (last 12 months) of 3.9x. ^2,3
• Cash and cash equivalents of $9 million, with a draw on the revolving line of credit of $52 million, at June 30, 2019.

• Amended revolving credit agreement to allow higher net debt/EBITDA ratios through the second quarter of 2020.
• Locked in minimum average prices of $1,400 per gold ounce and $15.13 per silver ounce by acquiring put options through the first quarter of 2020, while allowing full participation in potentially higher prices.

"Our financial performance in the second quarter was impacted by several items, including lower by-product credits and the timing of lead shipments at Greens Creek, and higher depreciation expense, which more than offset the positive impact of higher grades at Greens Creek," said Phillips S. Baker, Jr., President and CEO. "Silver production at Greens Creek continued to be strong due to higher grades, so we are increasing our estimates for silver production for the year. Casa Berardi per-ounce costs were higher due to lower production, which should improve in the second half of the year with changes made to the mill and expected higher grades. We were reminded of the strong exploration potential of Casa Berardi and San Sebastian this quarter with high-grade intersections underground in the East Mine at Casa and an expanding oxide discovery at El Toro at San Sebastian. Changes were made in June at the Nevada operations, so they did not have much impact on the financial results for the second quarter but should help improve the cash flow in the second half of the year."

Mr. Baker continued, "We have taken several steps in anticipation of refinancing our senior notes, due in 21 months. First, we bought put options that assure us of the minimum prices for the next few quarters that we receive for gold and silver. Next, we amended certain terms of our revolving credit agreement to improve availability to borrow funds. Finally, we have reduced expenditures, so we expect to be free cash flow positive in the third quarter and even more in the fourth quarter, enough to have no net revolver debt at year end. All of this should improve our debt to EBITDA profile heading into 2020."

FINANCIAL OVERVIEW

Net loss applicable to common shareholders for the second quarter 2019 was $46.7 million, or $0.10 per share, compared to net income applicable to common shareholders of $11.9 million, or $0.03 per share, for the same period in 2018. The second quarter result was mainly due to the following items:

• Gross loss in Nevada was $20.2 million, which includes $17.8 million in depreciation expense, due to higher costs and lower grades and recoveries. At Greens Creek, gross profit was $17.1 million lower, primarily due to pricing. While at Casa Berardi, gross profit was lower by $14.1 million as a result of 8,353 fewer gold ounces sold, than in the second quarter of 2018, due primarily to mill maintenance activities.
• Gain on metals derivative contracts of $3.8 million, compared to a gain of $16.8 million in the second quarter of 2018.
• Loss of $4.6 million on the sale of Hecla’s interest in the Fayolle property in Quebec.
• Net foreign exchange loss of $4.4 million compared to a gain of $2.5 million in the second quarter of 2018.

Cash used by operating activities was $11.3 million compared to cash provided by operating activities of $30.6 million in the second quarter of 2018, with the decrease mainly due to lower gross profit and timing of working capital changes.

Adjusted EBITDA was $22.9 million compared to $57.7 million in the second quarter of 2018, with the decrease mainly due to lower margins at Casa Berardi, negative results at our Nevada operations, and lower silver and base metals prices at Greens Creek.

Capital expenditures (excluding capitalized interest) at the operations totaled $38.9 million for the second quarter compared to $26.8 million in the second quarter of 2018, with the increase primarily due to the addition of the Nevada operations. Greens Creek and Casa Berardi expenditures decreased by $5.5 million and $0.4 million. Expenditures at Nevada operations, Casa Berardi, Greens Creek, San Sebastian and Lucky Friday were $17.3 million, $9.4 million, $8.7 million, $2.1 million, and $1.5 million respectively.

Metals Prices

The average realized silver price in the second quarter was $15.01 per ounce, 10% lower than the $16.61 in the second quarter of 2018. Average realized lead and zinc prices decreased 26% and 9%, respectively, while the average gold price increased 2%.

Metals Forward Sales Contracts

The following table summarizes the quantities of metals committed under financially settled forward sales contracts at June 30, 2019:

The forward contracts represent 14% of the forecasted payable zinc production for the 36-month period ended June 30, 2022 at an average price of $1.25 per pound and 3% of the forecasted payable lead production for the same period at an average price of $0.96 per pound.

Setting A Short-term Floor for Silver and Gold Prices

The Company has bought put option contracts in an amount approximating the expected silver and gold sales through a portion of 2020, setting a minimum average price of $1,400 per gold ounce and $15.13 per silver ounce. Buying a put option sets a floor on the price the Company expects to receive on substantially all of its projected near-term production while maintaining exposure to the upside, other than the transaction costs. This gives the Company confidence in the minimum prices it will receive.

OPERATIONS OVERVIEW

Overview

The following table provides the production summary on a consolidated basis for the second quarter and six months ended June 30, 2019 and 2018:

The following tables provide a summary of the final production, cost of sales, cash cost, after by?product credits, per silver and gold ounce, and AISC, after by-product credits, per silver and gold ounce for the second quarter and six months ended June 30, 2019, with comparisons to the prior year period:

Greens Creek Mine - Alaska

At the Greens Creek mine, 2.4 million ounces of silver and 13,257 ounces of gold were produced, compared to 2.0 million ounces and 13,719 ounces, respectively, in the second quarter of 2018. Silver production was the most in the last three years, and the increase compared to the second quarter of 2018 was due to higher grades. The mill operated at an average of 2,301 tons per day (tpd), which was slightly higher than the second quarter of 2018.

The cost of sales was $45.7 million, and the cash cost, after by-product credits, per silver ounce, was $2.38, compared to $47.7 million and $(3.47), respectively, for the second quarter of 2018.⁴ The AISC, after by-product credits, was $6.37 per silver ounce compared to $4.43 in the second quarter of 2018.⁵ The increased silver production means there is less by-product credit to apply to each ounce of silver so the cost per ounce after by-products is higher. The per ounce silver costs were higher primarily due to lower by-product metal prices and production, partially offset by higher silver production.

Production in the second half is expected to be similar to the first half, and to be spread fairly evenly between the third and fourth quarters, but due to shipment schedules the cash flow should mostly be in the fourth quarter.

Casa Berardi - Quebec

At the Casa Berardi mine, 31,270 ounces of gold were produced, including 6,685 ounces from the East Mine Crown Pillar (EMCP) pit, compared to 42,722 ounces in the second quarter of 2018. The decrease is primarily due to lower ore grades, and lower mill recovery as a result of planned adjustments to a number of mill components to accommodate a higher throughput and the requirement for a new carbon in leach (CIL) drive train, which was installed in May. The shortfall in production in the first half of the year is expected to be made up over the remainder of the year with the introduction of a pre-crush system and projected higher grades. The mill operated at an average of 3,820 tpd, which was slightly lower than the second quarter of 2018.

The cost of sales was $55.2 million and the cash cost, after by-product credits, per gold ounce was $1,101, compared to $51.7 million and $775, respectively, in the second quarter of 2018.^4,6 The increase in cash cost, after by-product credits, per gold ounce is mainly due lower gold production. Lower production, partially offset by lower capital spending, resulted in higher AISC, after by-product credits, of $1,437 per gold ounce, compared to $1,039 in the second quarter of 2018.⁵

Production and cash flow from Casa Berardi are expected to be higher in second half of the year, with the greater impact in the fourth quarter.

San Sebastian - Mexico

At the San Sebastian mine, 463,735 ounces of silver and 3,547 ounces of gold were produced, compared to 559,647 ounces and 3,872 ounces, respectively, in the second quarter of 2018. The decreases were due to lower grades, as expected, upon transitioning to increased throughput coming from underground material, versus higher-grade open pit material. The mill operated at an average of 504 tpd, which was 21% higher than the second quarter of 2018.

The cost of sales was $11.1 million and the cash cost, after by-product credits, was $9.22 per silver ounce, compared to $11.1 million and $9.79, respectively, in the second quarter of 2018. The cash cost, after by-product credits, decreased due to lower mining costs and higher by-product credits on a per-ounce basis. The AISC, after by-product credits, was $15.50 per silver ounce compared to $17.15 in the second quarter of 2018 with the variance due to the same factors along with lower capital and exploration spending.⁵

Production is expected to remain consistent with the first half of the year but with the cash flow weighted to the fourth quarter. A review of sulfide ore continues, including a bulk sample to test the capabilities of the third-party plant and the suitability of long-hole stoping for the ore body, with results expected by the fourth quarter of 2019.

Nevada Operations (acquired on July 20, 2018)

For the Nevada operations, 12,694 ounces of gold and 49,449 ounces of silver were produced. During the second quarter, a review of the Nevada operations was conducted and changes made. The mining contractor has been demobilized, and the decision made to mine only currently developed material at Fire Creek and to suspend production and development at Hollister. Mining at Midas is expected to continue through the end of the third quarter. Some surface exploration drilling and hydrology studies are still planned to gather information on the deposits to aid future development programs. Additional changes could also be taken with the goal of turning it into a positive cash flowing unit.

Third-party ore processing arrangements are also being pursued with the goal of reducing transportation and milling costs. This could include mills that can process ore that is considered refractory. With water discharge from Fire Creek higher than it was a year ago, work is underway to increase discharge permits, expected to be obtained in the near future and increase non-consumptive water rights, expected within approximately one year. These changes, combined with changing how the water is treated, are important steps towards addressing the increase in water inflow expected when the mine expands north and southwards.

Production and cash flow at the Nevada operations are expected to be higher in the second half of the year, particularly in the fourth quarter as a result of the reduction in development spending.

Lucky Friday Mine - Idaho

At the Lucky Friday Mine, 127,147 ounces of silver was produced compared to 24,687 ounces in the second quarter of 2018 mainly due to a shift in focus from development to production by the salaried staff. The higher level of production is helping to defray costs associated with the strike at Lucky Friday. Cost of sales was $5.0 million compared to $1.7 million in the second quarter of 2018, mainly the result of increased production.

The Remote Vein Miner (RVM) is fully fabricated. It is expected to begin operating at EPIROC's test mine in Sweden by the end of the summer, with delivery to Lucky Friday expected in the second quarter of 2020.

EXPLORATION

Exploration (including corporate development) expenses for the second quarter were $4.3 million, a decrease of $3.5 million compared to the prior year period.

A complete summary of exploration for the second quarter can be found in the exploration news release entitled "Hecla Reports New High-Grade at Casa Berardi and Expanding Near-Surface Oxide Resource at San Sebastian" issued on August 6, 2019.

PRE-DEVELOPMENT

Pre-development spending was $0.8 million for the quarter, compared to $1.4 million for the second quarter of 2018, principally to advance the permitting of Rock Creek and Montanore.

DIVIDENDS

Common

The Board of Directors elected to declare a quarterly cash dividend of $0.0025 per share of common stock, payable on or about September 3, 2019, to shareholders of record on August 23, 2019. The realized silver price was $15.01 in the second quarter and therefore did not satisfy the criteria for a larger dividend under the Company's dividend policy.

Preferred

The Board of Directors elected to declare a quarterly cash dividend of $0.875 per share of preferred stock, payable on or about October 1, 2019, to shareholders of record on September 13, 2019.

SENIOR MANAGEMENT CHANGES

Hecla today announced changes to its senior leadership structure.

Mr. Lauren Roberts joins the Company as its Senior Vice President and Chief Operating Officer. A mining engineer with over 30 years’ experience in the industry, Mr. Roberts has held progressively more senior roles at Kinross since joining them in 2004, ending as Senior Vice President and Chief Operating Officer. He previously worked for Hecla from 1989 to 1997 and then spent seven years at Barrick before joining Kinross.

Mr. Larry Radford, formerly Hecla’s Senior Vice President and Chief Operating Officer, transitions to the temporary role of Chief Technical Officer. He will assist with the transition of responsibilities to Lauren and lead the Technical Services and Project Development teams.

Mr. Dean McDonald, Senior Vice President, Exploration, is retiring. Since joining Hecla in 2006, Dean has been instrumental in the Company achieving record silver reserves in 10 of the past 11 years and strong growth in gold reserves.

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⁾ Adjusted net (loss) income applicable to common stockholders is a non-GAAP measurement, a reconciliation of which to net (loss) income applicable to common stockholders, the most comparable GAAP measure, can be found at the end of the release. Adjusted net (loss) income is a measure used by management to evaluate the Company's operating performance but should not be considered an alternative to net (loss) income, or cash (used in) 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.

⁽²⁾ Adjusted EBITDA is a non-GAAP measurement, a reconciliation of which to net (loss) 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 (loss) income, or cash (used in) 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.

⁽³⁾ Net debt to adjusted EBITDA is a non-GAAP measurement, a reconciliation of which to debt and net (loss) income, 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.

⁽⁴⁾ 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 silver and gold mining company, management also uses the statistic on an aggregate basis - aggregating the Greens Creek, Lucky Friday and San Sebastian 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 second quarters and first halves of 2019 and 2018, as production was limited due to the strike and results are not comparable to those from prior periods and are not indicative of future operating results under full production.

⁽⁵⁾ 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. AISC, after by-product credits, per silver ounce is not presented for Lucky Friday for the second quarters and first halves of 2019 and 2018, as production was limited due to the strike and results are not comparable to those from prior periods and are not indicative of future operating results under full production.

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 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.

⁽⁶⁾ Cash cost, after by-product credits, per gold ounce is only applicable to Casa Berardi and Nevada Operations production. Gold produced from Greens Creek and San Sebastian is treated as a by-product credit against the silver cash cost.

Other

⁽⁷⁾ Expectations for 2019 includes silver, gold, lead and zinc production from Greens Creek, San Sebastian, Casa Berardi, Nevada Operations and Lucky Friday converted using Au $1,400/oz, Ag $16.00/oz, Zn $1.10/lb, and Pb $0.90/lb. Prices formerly used were Au $1,250/oz, Ag $16.00/oz, Zn $1.25/lb, and Pb $1.00/lb.

Numbers may be rounded.

Qualified Person (QP) Pursuant to Canadian National Instrument 43-101

Dean McDonald, PhD. P.Geo., Senior Vice President - Exploration of Hecla Mining Company, who serves as a Qualified Person under National Instrument 43-101, supervised the preparation of the scientific and technical information concerning Hecla’s mineral projects in this news release. Information regarding data verification, surveys and investigations, quality assurance program and quality control measures and a summary of sample, analytical or testing procedures for the Greens Creek Mine are contained in a technical report prepared for Hecla titled “Technical Report for the Greens Creek Mine, Juneau, Alaska, USA” effective date March 28, 2013, and for the Lucky Friday Mine are contained in a technical report prepared for Hecla titled “Technical Report on the Lucky Friday Mine Shoshone County, Idaho, USA” effective date April 2, 2014, for the Casa Berardi Mine are contained in a technical report prepared for Hecla titled "Technical Report on the Mineral Resource and Mineral Reserve Estimate for the Casa Berardi Mine, Northwestern Quebec, Canada" effective date March 31, 2014 (the "Casa Berardi Technical Report"), and for the San Sebastian Mine are contained in a technical report prepared for Hecla titled "Technical Report for the San Sebastian Ag-Au Property, Durango, Mexico" effective date September 8, 2015. Also included in these three technical reports is a description of the key assumptions, parameters and methods used to estimate mineral reserves and resources and a general discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, title, taxation, socio-political, marketing or other relevant factors. Copies of these technical reports are available under Hecla's profile on SEDAR at www.sedar.com.

The current Casa Berardi drill program was performed on core sawed in half and included the insertion of blanks and standards of variable grade in every 24 core samples. Standards were generally provided by Analytical Solutions Ltd and prepared in 30-gram bags. Samples were sent to the Swastika Laboratories in Swastika, Ontario, a registered accredited laboratory, where they were dried, crushed, and split for gold analysis. Analysis for gold was completed by fire assay with AA finish. Gold over-limits were analyzed by fire assay with gravimetric finish. Data received from the lab were subject to validation using in-built program triggers to identify outside limit blank or standard assays that require re-analysis. Over 5% of the original pulps and rejects are sent for re-assay to ALS Chemex in Val d’Or for quality control.

Dr. McDonald reviewed and verified information regarding drill sampling, data verification of all digitally collected data, drill surveys and specific gravity determinations relating to the Casa Berardi mine. The review encompassed quality assurance programs and quality control measures including analytical or testing practice, chain-of-custody procedures, sample storage procedures and included independent sample collection and analysis. This review found the information and procedures meet industry standards and are adequate for Mineral Resource and Mineral Reserve estimation and mine planning purposes.

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 the Greens Creek, Lucky Friday, San Sebastian, Casa Berardi and Nevada Operations units for the three- and six-month periods ended June 30, 2019 and 2018 and for estimated result for the full-year of 2018.

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, royalties and mining production taxes. 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.
