Hecla's Fourth Quarter Continues a Strong Second Half Of 2019

February 6, 2020 3:30 AM

Hecla reports record annual revenue, gold production and silver reserves

COEUR D'ALENE, Idaho--(BUSINESS WIRE)-- Hecla Mining Company (NYSE:HL) today announced fourth quarter and full year 2019 financial and operating results.

HIGHLIGHTS

"2019 was a tale of two halves where the second half had higher production, higher prices, better earnings and more cash flow," said Phillips S. Baker, Jr., President and CEO. "The strong third and fourth quarters markedly improved our financial condition, putting us in a better position to refinance the Senior Notes."

"In 2020, at current prices, we expect continued strong cash flow generation with the ongoing solid performance at Greens Creek, the ramp-up of Lucky Friday, expected improvements at Casa Berardi and the potential mine life extension at San Sebastian from the Hugh Zone," Mr. Baker added.

SILVER AND GOLD RESERVE SUMMARY

Proven and probable reserves are 212 million ounces of silver, an increase of 11% over last year and 2.71 million ounces of gold, a decrease of 5%. Proven and probable lead and zinc reserves of 810,930 tons and 1,001,930 tons are increases of 5% and 8%, respectively. The reserves for silver, lead and zinc are the highest in Company history. The price assumptions used for 2019 reserves of $14.50 for silver, $1.15 for zinc and $0.90 for lead are unchanged this year and our assumption for gold is $100 higher at $1,300 per ounce. The silver price assumption is among the lowest in the industry again this year.

Please refer to the reserves and resources tables at the end of this press release, or to the press release entitled "Hecla Reports Record Silver, Lead and Zinc Reserves" released on February 5, 2020, for the breakdown between proven and probable reserve and resource levels, as well as a detailed summary of the Company's exploration programs.

Net loss applicable to common stockholders for the fourth quarter and full year of 2019 was $8.1 million and $100.1 million, or $0.02 and $0.20 per basic share, respectively, compared to net losses applicable to common stockholders of $23.8 million and $27.1 million, or $0.05 and $0.06 per basic share, respectively, for the fourth quarter and full year of 2018. Among items impacting the results for the 2019 periods compared to 2018 were the following:

Cash provided by operating activities for the fourth quarter and full year of 2019 of $57.3 million and $120.9 million, respectively, was $38.2 million and $26.6 million higher, respectively, compared to the prior year periods. The increase in the fourth quarter of 2019 was primarily due to lower spending in Nevada, higher sales and lower exploration. The increase for the full year of 2019 was a result of the same factors, along with lower acquisition costs and Lucky Friday suspension costs and the impact of working capital changes, partially offset by lower cash proceeds from settlement of base metals derivative contracts prior to their maturity date.

Adjusted EBITDA increased $43.2 million quarter-over-quarter, and the $177.7 million in 2019 was $6.4 million more than 2018.1 The increases were primarily due to lower spending in Nevada, higher sales, and lower exploration spending.

Fourth quarter capital expenditures totaled $23.8 million, including $12.9 million at Greens Creek, $7.7 million at Casa Berardi, and $3.0 million at Lucky Friday. Capital expenditures, including non-cash items for equipment acquired under finance leases, for the year 2019 totaled $128.1 million, compared to last year's $140.6 million.

Metals Prices

Average realized silver prices in the fourth quarter and full year 2019 were $17.47 and $16.65 per ounce, respectively, compared to $14.58 and $15.63, respectively, for the prior year periods. Average realized prices for gold for the fourth quarter and full year 2019 were $1,488 and $1,413 per ounce, respectively, higher by 20% and 12%, respectively, compared to the prior year periods. Average realized prices for lead were 3% higher, with the zinc price 4% lower quarter-over-quarter. The average realized prices for lead and zinc for the full year of 2019 were 13% and 10% lower, respectively, compared to 2018.

Greens Creek Mine - Alaska

The increase in silver and gold production for the quarter and full year resulted from higher grades, with the quarterly increase also due to higher throughput. The mill operated at an average of 2,351 tons per day (tpd) in the fourth quarter and 2,318 tpd for the full year. The annual throughput was a record.

The higher cost of sales and per silver ounce cash costs, for the periods were primarily due to higher production costs and treatment charges. The decrease in AISC per silver ounce, for the quarter resulted from higher silver production.

For the full year of 2019, Greens Creek generated cash provided by operating activities of approximately $136.2 million and spent $29.3 million on additions to properties, plants and equipment, resulting in free cash flow of $106.9 million.5

Casa Berardi - Quebec

Lower quarterly and annual gold production was due to lower grades, as planned. Gold production was also impacted by lower mill throughput and recoveries in the first half of 2019 due to planned adjustments to a number of mill components to accommodate higher throughput, and the requirement for a new carbon in leach (CIL) tank drive-train, which was installed in May 2019. The mill operated at an average of 3,950 tpd in the fourth quarter 2019 and 3,775 tpd for the year.

Higher quarterly and annual cost of sales were due to the extension of stripping at the East Mine Crown Pillar (EMCP) pit as well as increased quantities of waste and ore extracted from the pit and higher haulage costs due to deepening of the pit. Milling costs were also higher due to costs for pre-crushing of ore to allow for increased throughput, and higher costs for mill enhancements, maintenance and reagents. These factors impacting mining and milling costs, along with lower gold production, also resulted in increased cash costs per gold ounce. However, AISC per gold ounce declined in the fourth quarter due to lower capital spending.

For the full year of 2019, Casa Berardi generated cash provided by operating activities of approximately $55.7 million and spent $35.8 million on additions to properties, plants and equipment, resulting in free cash flow of $20.0 million.5

Process improvement studies are being implemented in 2020 in an effort to improve throughput, recovery and lower costs to increase cash flow.

San Sebastian - Mexico

San Sebastian's lower metal production was expected due to the transition from shallow, high-grade open pits to lower-grade underground production. The mill operated at an average of 425 tpd in the fourth quarter 2019 and 479 tpd for the year.

The higher cost of sales was due to the higher cost of underground mining and depreciation. Cash cost and AISC per ounce, after by-product credits, were lower as a result of higher by-product credits, due to higher gold production prices, with AISC also impacted by lower exploration spending.

For the full year of 2019, San Sebastian generated cash provided by operating activities of approximately $19.1 million and spent $5.0 million on additions to properties, plants and equipment, resulting in free cash flow of $14.1 million.5

The Company is completing its study on the Hugh Zone sulfide ore and expects a decision on development in the first quarter, which would allow production to begin by the end of the year.

Nevada Operations

Gold production was 9% higher quarter-over-quarter. The assets were acquired on July 20, 2018. During 2019, ore was processed at an average of 576 tpd.

Cost of sales for the year rose primarily as a result of reporting a full year's results, and were higher for the fourth quarter due to higher sales volume and increased depreciation. However, per gold ounce cash costs and AISC declined for the fourth quarter by $305 and $996 per gold ounce because of increased gold production resulting from higher grades, with the decrease in AISC also due to lower exploration spending, partially offset by higher sustaining capital.

The mining of developed ore is expected to continue at Fire Creek until about mid-year, when the mining activities are planned to pause. To lower the cut-off grade, the Company is studying mining methods, processing of refractory ore and hydrology. Production is not anticipated to begin again until these studies are successfully completed and permitted.

Lucky Friday Mine - Idaho

Production in 2019 was similar to 2018 with the production and capital improvements being performed by salaried staff.

Union workers at Lucky Friday ratified the collective bargaining agreement in January 2020, and many are beginning to return to work. The Company anticipates re-staffing of the mine to take place in stages, with a ramp-up to full production levels expected by the end of 2020.

Underground testing and modification of the Remote Vein Mining (RVM) machine is underway in Sweden. The machine is expected to be sent to Lucky Friday by late 2020.

EXPLORATION AND PRE-DEVELOPMENT

Exploration

Exploration (including corporate development) expenses were $2.4 million and $15.9 million for the fourth quarter and full year 2019, respectively. This represents a decrease of 71% and 55% over the fourth quarter and full year 2018. These decreases were primarily the result of lower expenses at the Nevada operations and overall decreased site exploration during 2019.

A complete summary of exploration activities can be found in the news release entitled "Hecla Reports Record Silver, Lead and Zinc Reserves" released on February 5, 2020.

Pre-development

Pre-development spending was $0.6 million in the fourth quarter and $3.2 million for the full year 2019, principally to advance the permitting at Rock Creek and Montanore.

Rock Creek/Montanore

At Rock Creek, the Company updated and the Kootenai National Forest partially approved its plan of operation to reflect the Record of Decision (ROD) issued in 2018. In December 2019, the Company submitted an amendment application to the Montana Department of Environmental Quality to modify the existing Exploration License to match the ROD. The Company plans to continue the permitting process at the site despite the existence of litigation challenging the project.

At Montanore, the Kootenai National Forest issued a draft Supplemental Environmental Impact Study for the evaluation phase for public comment in the third quarter of 2019. The project remains the subject of ongoing litigation. The Company plans to continue the permitting process at the site despite the existence of litigation challenging the project.

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.

(2) 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, Lucky Friday and San Sebastian mines - to compare performance with that of other primary silver mining companies. 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. 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.

(3) 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.

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.

(4) Cash cost, after by-product credits, per gold ounce, is a Non-GAAP measurement 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.

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

Other

(6) Expectations for 2020 include silver, gold, lead and zinc production from Greens Creek, Lucky Friday, San Sebastian, Casa Berardi and Nevada Operations converted using Au $1,525/oz, Ag $17/oz, Zn $1.00/lb, and Pb $0.85/lb. Numbers may be rounded.

Cautionary Statement Regarding Forward Looking Statements, Including 2020 Outlook

This news release contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which are intended to be covered by the safe harbor created by such sections and other applicable laws, including Canadian securities laws. Such forward-looking statements may include, without limitation: (i) estimates of full-year 2020 silver and gold production, cost of sales, cash costs, after by-product credits, AISC, after by-product credits as well as estimated spending on capital, exploration, pre-development and research and development (which assumes metal prices of gold at $1,525/oz, Ag $17/oz, Zn $1.00/lb, Pb $0.85/lb; USD/CAD assumed to be $0.77, USD/MXN assumed to be $0.05; (ii) the Company’s mineral reserves and resources; (iii) the strong second half of 2019 puts Hecla in a better position to refinance the Senior Notes; (iv) expectations that strong cash flow generation will continue in 2020; (v) ramp-up of Lucky Friday to full production by the end of 2020; (vi) potential mine life extension at San Sebastian from the Hugh zone with production beginning later this year; (vii) improvement studies underway at Casa Berardi in an effort to improve throughput, recovery and cost gains to increase cash flow; (viii) number of employees at Lucky Friday that return to work; (ix) expectation that the RVM to be sent to Lucky Friday following successful completion of testing, estimated to be in late 2020; and (x) the ability to continue the permitting process at Rock Creek and Montanore despite litigation. Estimates or expectations of future events or results are based upon certain assumptions, which may prove to be incorrect. Such assumptions, include, but are not limited to: (a) there being no significant change to current geotechnical, metallurgical, hydrological and other physical conditions; (b) permitting, development, operations and expansion of the Company’s projects being consistent with current expectations and mine plans; (c) political/regulatory developments in any jurisdiction in which the Company operates being consistent with its current expectations; (d) the exchange rate for the Canadian dollar to the U.S. dollar, being approximately consistent with current levels; (e) certain price assumptions for gold, silver, lead and zinc; (f) prices for key supplies being approximately consistent with current levels; (g) the accuracy of our current mineral reserve and mineral resource estimates; and (h) the Company’s plans for development and production will proceed as expected and will not require revision as a result of risks or uncertainties, whether known, unknown or unanticipated. Where the Company expresses or implies an expectation or belief as to future events or results, such expectation or belief is expressed in good faith and believed to have a reasonable basis. However, such statements are subject to risks, uncertainties and other factors, which could cause actual results to differ materially from future results expressed, projected or implied by the “forward-looking statements.” Such risks include, but are not limited to gold, silver and other metals price volatility, operating risks, currency fluctuations, increased production costs and variances in ore grade or recovery rates from those assumed in mining plans, community relations, conflict resolution and outcome of projects or oppositions, litigation, political, regulatory, labor and environmental risks, and exploration risks and results, including that mineral resources are not mineral reserves, they do not have demonstrated economic viability and there is no certainty that they can be upgraded to mineral reserves through continued exploration. For a more detailed discussion of such risks and other factors, see the Company’s 2018 Form 10-K, filed on February 22, 2019, with the Securities and Exchange Commission (SEC), as well as the Company’s other SEC filings, including the Company's 2019 10-K expected to be filed on February 10, 2020. The Company does not undertake any obligation to release publicly revisions to any “forward-looking statement,” including, without limitation, outlook, to reflect events or circumstances after the date of this news release, or to reflect the occurrence of unanticipated events, except as may be required under applicable securities laws. Investors should not assume that any lack of update to a previously issued “forward-looking statement” constitutes a reaffirmation of that statement. Continued reliance on “forward-looking statements” is at investors’ own risk.

Cautionary Statements to Investors on Reserves and Resources

Reporting requirements in the United States for disclosure of mineral properties are governed by the SEC and included in the SEC's Securities Act Industry Guide 7, entitled “Description of Property by Issuers Engaged or to be Engaged in Significant Mining Operations” (Guide 7). Although the SEC has recently issued new rules rescinding Guide 7, the new rules are not binding until January 1, 2021, and at this time the Company still reports in accordance with Guide 7. However, the Company is also a “reporting issuer” under Canadian securities laws, which require estimates of mineral resources and reserves to be prepared in accordance with Canadian National Instrument 43-101 (NI 43-101). NI 43-101 requires all disclosure of estimates of potential mineral resources and reserves to be disclosed in accordance with its requirements. Such Canadian information is included herein to satisfy the Company's “public disclosure” obligations under Regulation FD of the SEC and to provide U.S. holders with ready access to information publicly available in Canada.

Reporting requirements in the United States for disclosure of mineral properties under Guide 7 and the requirements in Canada under NI 43-101 standards are substantially different. This document contains a summary of certain estimates of the Company, not only of proven and probable reserves within the meaning of Guide 7, but also of mineral resource and mineral reserve estimates estimated in accordance with the definitional standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in NI 43-101. Under Guide 7, the term "reserve" means that part of a mineral deposit that can be economically and legally extracted or produced at the time of the reserve determination. The term "economically", as used in the definition of reserve, means that profitable extraction or production has been established or analytically demonstrated to be viable and justifiable under reasonable investment and market assumptions. The term "legally", as used in the definition of reserve, does not imply that all permits needed for mining and processing have been obtained or that other legal issues have been completely resolved. However, for a reserve to exist, Hecla must have a justifiable expectation, based on applicable laws and regulations, that issuance of permits or resolution of legal issues necessary for mining and processing at a particular deposit will be accomplished in the ordinary course and in a timeframe consistent with Hecla's current mine plans. The terms “measured resources”, “indicated resources,” and “inferred resources” are Canadian mining terms as defined in accordance with NI 43-101. These terms are not defined under Guide 7 and are not normally permitted to be used in reports and registration statements filed with the SEC in the United States, except where required to be disclosed by foreign law. The term “resource” does not equate to the term “reserve”. Under Guide 7, the material described herein as “indicated resources” and “measured resources” would be characterized as “mineralized material” and is permitted to be disclosed in tonnage and grade only, not ounces. The category of “inferred resources” is not recognized by Guide 7. Investors are cautioned not to assume that any part or all of the mineral deposits in such categories will ever be converted into proven or probable reserves. “Resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of such a “resource” will ever be upgraded to a higher category or will ever be economically extracted. Investors are cautioned not to assume that all or any part of a “resource” exists or is economically or legally mineable. Investors are also especially cautioned that the mere fact that such resources may be referred to in ounces of silver and/or gold, rather than in tons of mineralization and grades of silver and/or gold estimated per ton, is not an indication that such material will ever result in mined ore which is processed into commercial silver or gold.

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

Kurt D. Allen, MSc., CPG, Director - Exploration of Hecla Limited and Keith Blair, MSc., CPG, Chief Geologist of Hecla Limited, who serve as a Qualified Person under National Instrument 43-101("NI 43-101"), supervised the preparation of the scientific and technical information concerning Hecla’s mineral projects in this news release, including with respect to the newly acquired Nevada projects. Information regarding data verification, surveys and investigations, quality assurance program and quality control measures and a summary of analytical or testing procedures for the Greens Creek Mine are contained in a technical report titled “Technical Report for the Greens Creek Mine” effective date December 31, 2018, and for the Lucky Friday Mine are contained in a technical report titled “Technical Report for the Lucky Friday Mine Shoshone County, Idaho, USA” effective date April 2, 2014, for Casa Berardi are contained in a technical report titled "Technical Report on the mineral resource and mineral reserve estimate for Casa Berardi Mine, Northwestern Quebec, Canada" effective date December 31, 2018 (the "Casa Berardi Technical Report"), and for the San Sebastian Mine, Mexico, 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 four 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. 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 Fire Creek Mine are contained in a technical report prepared for Klondex Mines, dated March 31, 2018; the Hollister Mine dated May 31, 2017, amended August 9, 2017; and the Midas Mine dated August 31, 2014, amended April 2, 2015. Copies of these technical reports are available under Hecla's and Klondex's profiles on SEDAR at www.sedar.com. Mr. Allen and Mr. Blair reviewed and verified information regarding drill sampling, data verification of all digitally-collected data, drill surveys and specific gravity determinations relating to all the mines. 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.

(1) Cash cost, after by-product credits, per ounce and AISC, after by-product credits. per ounce represent non-U.S. Generally Accepted Accounting Principles (GAAP) measurements. A reconciliation of cost of sales and other direct production costs and depreciation, depletion and amortization (GAAP) to cash cost, after by-product credits 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.

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 and for the Company for the three- and twelve-month periods ended December 31, 2019 and 2018, and for estimated amounts for the twelve months ended December 31, 2020.

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 mines' 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 mines versus those of our competitors. As a primary silver and gold mining company, we also use these statistics on an aggregate basis. We aggregate the Greens Creek, Lucky Friday and San Sebastian mines to compare our performance with that of other primary silver mining companies and aggregate the Casa Berardi and Nevada Operations units 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 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, exploration and sustaining capital projects. 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.

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 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 similar gold metrics for Casa Berardi.

Reconciliation of Net (Loss) Income Applicable to Common Shareholders (GAAP) to Adjusted Net Income (Loss) 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.

Reconciliation of Net 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 tax provision, depreciation, depletion, and amortization expense, exploration expense, pre-development expense, acquisition costs, interest and other income (expense), foreign exchange gains and losses, gains and losses on derivative contracts, unrealized gains on investments, provisions for environmental matters, stock-based compensation, and provisional price gains and losses. 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 Cash Provided by Operating Activities (GAAP) to Free Cash Flow (non-GAAP)

This release refers to a non-GAAP measure of free cash flow, calculated as cash provided by operating activities, less additions to properties, plants, equipment and mineral interests and a one-time item for settlement of an insurance policy for reclamation of the Troy Mine. Management believes that, when presented in conjunction with comparable GAAP measures, free cash flow is useful to investors in evaluating our operating performance. The following table reconciles cash provided by operating activities to free cash flow:

The term “reserve” means that part of a mineral deposit that can be economically and legally extracted or produced at the time of the reserve determination. The term “economically,” as used in the definition of reserve, means that profitable extraction or production has been established or analytically demonstrated to be viable and justifiable under reasonable investment and market assumptions. The term “legally,” as used in the definition of reserve, does not imply that all permits needed for mining and processing have been obtained or that other legal issues have been completely resolved. However, for a reserve to exist, Hecla must have a justifiable expectation, based on applicable laws and regulations, that issuance of permits or resolution of legal issues necessary for mining and processing at a particular deposit will be accomplished in the ordinary course and in a timeframe consistent with Hecla’s current mine plans.

(2)

Mineral reserves are based on $1300 gold, $14.50 silver, $0.90 lead, $1.15 zinc, unless otherwise stated. The NSR cut-off grades are $190/ton for Greens Creek, $216.19 for the 30 Vein and $230.98 for the Intermediate Veins at Lucky Friday, and $127/ton ($140/tonne) for underground and $90.72/ton ($100/tonne) for open pit reserves at San Sebastian.

(3)

Mineral reserves are based on $1300 gold and a US$/CAN$ exchange rate of 1:1.35 Reserve diluted to an average of 34.7% to minimum width of 9.8 feet (3 m). The average cut-off grades at Casa Berardi are 0.105 oz/ton gold (3.49 g/tonne) for underground mineral reserves and 0.025 oz/ton gold (0.85 g/tonne) for open pit mineral reserves.

(4)

Fire Creek mineral reserves are based on a cut-off grade of 0.433 gold equivalent oz/ton and incremental cut-off grade of 0.135 gold equivalent oz/ton. Unplanned dilution of 10% to 17% included depending on mining method.
