Net income applicable to common shareholders for the third quarter was $13.5 million, or $0.03 per share, compared to net loss of $19.7 million, or $0.04 per share, for the same period a year ago. The difference was mainly due to the following items:

• Improved gross profit at Greens Creek, Nevada Operations and San Sebastian, partially offset by slightly lower gross profit at Casa Berardi. Combined, our operations generated $38.6 million more gross profit.
• Higher other operating expense by $3.1 million primarily due to costs for an ongoing project to identify and implement potential operational improvements at Casa Berardi.
• Lower ramp-up and suspension-related costs by $2.2 million due to increased production and margins at Lucky Friday.
• Unrealized gains on equity investments of $4.0 million compared to losses of $0.1 million in the prior year period.

Cash provided by operating activities was $73.4 million compared to $54.9 million in the third quarter of 2019, with the increase due to higher income, adjusted for non-cash items.

Adjusted EBITDA was $75.7 million compared to $69.8 million in the third quarter of 2019.

Capital expenditures totaled $23.7 million for the third quarter 2020 compared to $26.1 million in the third quarter of 2019, with the decrease due to planned lower expenditures at the operations in 2020 with the exception of Lucky Friday, where we have been returning the mine to full production. Expenditures at the operations were $11.6 million at Casa Berardi, $5.6 million at Greens Creek, $5.5 million at Lucky Friday, $0.4 million at Hecla Nevada, and $0.2 million at San Sebastian.

Metals Prices

The average realized silver price in the third quarter 2020 was 39% higher quarter over quarter and the average realized gold price was 31% higher. The realized zinc price increased by 7%, while the realized lead price decreased by 8%. Based on the realized silver price for the quarter of $25.32 per ounce, a silver price-linked dividend of $0.005 per common share was triggered.

Greens Creek Mine – Alaska

At the Greens Creek Mine, 2.6 million ounces of silver and 12,838 ounces of gold were produced, compared to 2.5 million ounces and 13,684 ounces, respectively, in the third quarter of 2019. Higher silver production was a result of slightly higher ore production and grades. The mill operated at an average of 2,340 tons per day (tpd) in the third quarter, a similar throughput as the third quarter of 2019.

The cost of sales for the third quarter was $51.1 million, and the cash cost, after by-product credits, per silver ounce, was $4.12, compared to $40.5 million and $2.05, respectively, for the third quarter of 2019.^5,6 The AISC, after by-product credits, was $7.70 per silver ounce for the third quarter compared to $6.05 in the third quarter of 2019.⁷ The per ounce silver cash costs were higher primarily due to higher treatment costs resulting from unfavorable changes in smelter terms and COVID-19 mitigation costs. AISC was also higher due to these factors, partially offset by lower capital spending.

Lucky Friday Mine - Idaho

At the Lucky Friday Mine, 636,389 ounces of silver were produced, compared to 115,682 ounces in the third quarter of 2019. The mine has continued normal operations during the pandemic, with the ramp-up ahead of schedule. Lucky Friday, starting in the fourth quarter, will achieve full production with estimated annual production in excess of 3 million ounces of silver in 2021.

Underground testing and modification of the Remote Vein Miner (RVM) continued in Sweden, but with limitations due to COVID-19. In parallel, the Company is testing alternative mining methods to increase productivity at the mine.

Casa Berardi Mine - Quebec

At the Casa Berardi Mine, 26,405 ounces of gold were produced, including 6,800 ounces from the East Mine Crown Pillar (EMCP) pit compared to 36,547 ounces in the third quarter of 2019. The decrease is primarily due to lower mill throughput resulting from longer than planned down time of major mill maintenance activities, along with lower ore grades due to a delay in the availability of higher-grade underground stopes as a result of ground condition challenges. We anticipate ore from these higher-grade stopes to be mined and processed in the fourth quarter. The mill operated at an average of 3,138 tpd in the third quarter, a decrease of 14% over the third quarter of 2019.

The cost of sales was $53.8 million and the cash cost, after by-product credits, per gold ounce was $1,398, compared to $53.0 million and $966, respectively, in the prior year period.^5,6 The increase in cash cost, after by-product credits, per gold ounce is primarily due to the lower gold production from the longer than scheduled major mill repairs and two high-grade long hole stopes being delayed in the third quarter. These same factors, partially offset by lower capital and exploration spending, resulted in AISC, after by-product credits, of $1,855 per gold ounce compared to $1,348 in the third quarter of 2019.⁷

San Sebastian Mine - Mexico

At the San Sebastian Mine, 266,691 ounces of silver and 1,931 ounces of gold were produced, compared to 541,636 ounces and 4,699 ounces, respectively, in the third quarter of 2019. The lower silver and gold production was expected and the result of lower ore grades. The mill operated at an average of 512 tpd, an increase of 4% over the third quarter of 2019.

The cost of sales was $6.0 million and the cash cost, after by-product credits, was $7.53 per silver ounce, compared to $12.8 million and $3.70, respectively, in the third quarter of 2019.^5,6 The AISC, after by-product credits, was $8.87 per silver ounce for the third quarter compared to $7.21 in the third quarter of 2019.⁷ The increase in per ounce costs was primarily due to lower silver production.

Mining was completed in the third quarter and milling is expected to be completed in the fourth quarter of 2020. The Company continues to explore this highly prospective land package and will evaluate further mining based on exploration success.

Nevada Operations

At the Nevada operations, ore mined during the quarter has been stockpiled for the third-party processing expected in the fourth quarter. Gold production will not be realized until 2021. Mining of non-refractory ore is substantially complete. Mining of refractory ore is expected to continue through the remainder of 2020. Production from the processing of the refractory ore is expected to be about 5 thousand ounces of gold.

EXPLORATION

Exploration (including corporate development) expenses were $3.4 million, a decrease of $1.4 million compared to the third quarter of 2019, primarily due to decreased activity at all sites mainly related to COVID-19 precautions. Turnaround time for assay results has also been longer than normal during the year due to assay laboratory delays related to COVID-19 and increased overall sample loads.

Greens Creek – Alaska

At Greens Creek, one drill rig program was focused on the 200S Zone, approximately 750 feet south of existing mining. A second drill rig was mobilized to site in October to bring drilling at Greens Creek back to pre-pandemic levels. Strong definition drilling assay results confirmed and upgraded 200S Zone resources, including 20.2 oz/ton silver, 0.02 oz/ton gold, 6.3% zinc and 2.9% lead over 28.5 feet and 30.3 oz/ton silver, 0.03 oz/ton gold, 18.2% zinc and 9.7% lead over 8.0 feet on the upper bench structure. Drilling targeting the lower contact returned 31.6 oz/ton silver, 0.22 oz/ton gold, 1.2% zinc and 0.6% lead over 32.9 feet.

In the fourth quarter of 2020 definition drilling is planned in the Upper Plate, 9a, East Ore, West, and Northwest West ore zones with lesser amounts of pre-production drilling in the 9a and 5250 ore zones. The two drilling rigs are currently active on the East Zone and the Upper Plate Zone.

More complete drill assay highlights from Greens Creek can be found in Table A at the end of the release.

Casa Berardi – Quebec

At Casa Berardi, drilling in the East Mine focused on defining continuity and expanding mineralization in the 160 Zone Pit area and in the 148 Zone. Definition drilling in the 160 Zone targeted mineralization below the current 160 Pit shell to further define the continuity of the 160 lenses at depth. Intersections from this drilling included 0.07 oz/ton gold over 108.2 feet, 0.10 oz/ton gold over 59.7 feet, and 0.06 oz/ton gold over 138.4 feet including 0.11 oz/ton gold over 8.9 feet and expands mineralization in the 160-03 and 160-04 lenses at depth plunging to the east. Exploration drilling in the East Mine occurred in the 148 Zone from underground targeting the down-plunge trend of the known high-grade mineralization. Intersections include 0.67 oz/ton gold over 9.8 feet located 98 feet below the currently defined 148-01 lens limit at the contact of the Casa Berardi Fault. Exploration drilling in the 159 Zone located just south of the 160 Zone Pit area intersected a narrow high-grade vein containing 0.41 oz/ton gold over 5.6 feet including 0.84 oz/ton gold over 2.6 feet. This vein is open for expansion to the east and at depth.

In the West Mine area, definition and exploration drilling focused on defining and expanding mineralization in the Upper 123 Zone from the 350 level, the Lower 123 Zone from the 1070 level, and the 128 Zone from the 490 level. Recent high-grade intersections from the Upper 123 Zone indicate the 123-01 lens is open for expansion up dip and include 0.91 oz/ton gold over 9.2 feet, 0.63 oz/t gold over 9.6 feet, and 0.51 oz/ton gold over 9.8 feet. Drilling in the 128 Zone identifies that two additional lenses, one to the north and one to the south of the 128-01 lens. Intersections include 0.91 oz/ton gold over 1.0 feet and 0.12 oz/ton gold over 17.7 feet including 0.23 oz/ton gold over 3.3 feet and 0.31 oz/ton gold over 3.9 feet. These initial results indicate mineralization is open at depth for expansion.

In the fourth quarter of 2020, underground drilling will focus on refining and expanding resources in the 123, 124, and 128 zones in the West Mine and the 148, 159, and 160 zones in the East Mine.

More complete drill assay highlights from Casa Berardi can be found in Table A at the end of the release.

San Sebastian - Mexico

At San Sebastian two core rigs operated throughout the quarter, one at the newly discovered El Bronco Vein and one at the newly discovered El Tigre Vein. The El Bronco Vein was discovered late in the second quarter and the El Tigre Vein was discovered early in the third quarter of this year as a result of short vertical reverse circulation (SVRC) drilling in areas with thick soil cover. These two new blind vein discoveries represent strong new structures to explore for zones of high-grade mineralization and continue to demonstrate the excellent prospectivity of the San Sebastian District and the effectiveness of SVRC drilling to discover new veins under cover.

Early drilling at the El Bronco Vein produced positive results with a recent drillhole returning: 0.29 oz/ton gold, 20.7 oz/ton silver over 4.2 feet (true width). Follow-up offset drilling of this intercept is currently in progress. The El Tigre Vein is a strong vein structure with an average true width in the first seven holes of 12.8 feet. Step-out drilling at both the El Bronco and El Tigre veins on approximately 300-foot centers is in progress and scheduled to continue into the fourth quarter of 2020 and into 2021.

More complete drill assay highlights from San Sebastian can be found in Table A at the end of the release.

Midas - Nevada

At Midas, four core rigs operated in September and will continue drilling into late November testing high-priority targets. Detailed mapping and sampling, geology modeling, alteration mineral speciation, and CSAMT geophysics during the first two quarters of 2020 defined numerous high-priority drilling targets at Midas including the Green Racer Sinter, Elko Prince, North Block, Southern Cross, SV1, Jackknife Ridge, and G3 target areas. Targets were prioritized based on anomalous gold, silver, and pathfinder elements, strong alteration associated with a boiling hydrothermal system at depth, and structural preparation. Because they were outside the Plan of Operations, many of these targets have never been drill tested or limited previous drilling did not adequately test the target. Initial drill testing of these targets began late in the third quarter beginning with the Green Racer Sinter, North Block, Southern Cross, and SV1 targets. Assay results are pending for drilling completed to date.

⁽³⁾ Net debt to adjusted EBITDA is a non-GAAP measurement, a reconciliation of which to debt and net income (loss), the most comparable GAAP measurements, can be found at the end of the release. It is an important measure for management to measure relative indebtedness and the ability to service the debt relative to its peers. It is calculated as total debt outstanding less total cash on hand divided by adjusted EBITDA.

⁽⁴⁾ Free cash flow is a non-GAAP measure, a calculation of which can be found at the end of the release. Free cash flow is calculated as cash provided by (used in) operating activities, less additions to properties, plants, equipment and mineral interests ("Capital Expenditures"). It is a measure used by management to evaluate the Company's operating performance but should not be considered an alternative to cash provided by (used in) operating activities as those terms are defined by GAAP, and does not necessarily indicate whether cash flows will be sufficient to fund cash needs. Management believes that, when presented in conjunction with comparable GAAP measures, free cash flow is useful to investors in evaluating our operating performance.

⁽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 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 third quarters and first nine-month periods of 2020 and 2019, as production was limited due to the strike and subsequent ramp-up and results are not comparable to those from prior periods and are not indicative of future operating results under full production.

⁽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.

⁽⁷⁾ 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 third quarters and first nine-month periods of 2020 and 2019, as production was limited due to the strike and subsequent ramp-up and results are not comparable to those from prior periods and are not indicative of future operating results under full production.

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.

Other

⁽⁸⁾ Expectations for 2020 include silver, gold, lead and zinc production from Greens Creek, Lucky Friday, San Sebastian, Casa Berardi and Nevada Operations converted using $1,525 gold, $17 silver, $0.85 lead, and $1.00 zinc; these haven’t changed from the first quarter.

Prices for by-product credits were calculated using actual realized prices through the third quarter, and $1,650 gold, $18.00 silver, $0.85 lead, and $0.95 zinc, resulting in full year prices of $1,721 gold, $19.26 silver, $0.82 lead, and $0.95 zinc.

Numbers may be rounded.

Cautionary Statements to Investors on Forward-Looking Statements

This 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. When a forward-looking statement 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. Forward-looking statements often address our expected future business and financial performance and financial condition and often contain words such as “anticipate,” “intend,” “plan,” “will,” “could,” “would,” “estimate,” “should,” “expect,” “believe,” “project,” “target,” “indicative,” “preliminary,” “potential” and similar expressions. Forward-looking statements in this news release may include, without limitation: (i) estimates of future production, sales, costs, and capital expenditures; (ii) expectations regarding the development, growth potential, financial performance of the Company’s projects, including that Lucky Friday will be at full production in the fourth quarter and that estimated annual production for 2021 will be in excess of 3 million ounces in 2021; (iii) the effectiveness of the Company's protocols to mitigate the risks presented by COVID-19; and (iv) expected improvement at Casa Berardi, including related mining and processing ore from higher-grade stopes in the fourth quarter. The material factors or assumptions used to develop such forward-looking statements or forward-looking information include that 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, to which the Company’s operations are subject.

Estimates or expectations of future events or results are based upon certain assumptions, which may prove to be incorrect, which could cause actual results to differ from forward-looking statements. Such assumptions, include, but are not limited to: (i) there being no significant change to current geotechnical, metallurgical, hydrological and other physical conditions; (ii) permitting, development, operations and expansion of the Company’s projects being consistent with current expectations and mine plans; (iii) political/regulatory developments in any jurisdiction in which the Company operates being consistent with its current expectations; (iv) the exchange rate for the USD/CAD and USD/MXN, being approximately consistent with current levels; (v) certain price assumptions for gold, silver, lead and zinc; (vi) prices for key supplies being approximately consistent with current levels; (vii) the accuracy of our current mineral reserve and mineral resource estimates; (viii) 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; (ix) counterparties performing their obligations under hedging instruments and put option contracts; (x) sufficient workforce is available and trained to perform assigned tasks; (xi) weather patterns and rain/snowfall within normal seasonal ranges so as not to impact operations; (xii) relations with interested parties, including Native Americans, remain productive; (xiii) economic terms can be reached with third-party mill operators who have capacity to process our ore; (xiv) maintaining availability of water rights; (xv) factors do not arise that reduce available cash balances, (xvi) there being no material increases in our current requirements to post or maintain reclamation and performance bonds or collateral related thereto, and (xvii) the Company's plans for refinancing its high yield notes proceeding as expected.

In addition, material risks that could cause actual results to differ from forward-looking statements include, but are not limited to: (i) gold, silver and other metals price volatility; (ii) operating risks; (iii) currency fluctuations; (iv) increased production costs and variances in ore grade or recovery rates from those assumed in mining plans; (v) community relations; (vi) conflict resolution and outcome of projects or oppositions; (vii) litigation, political, regulatory, labor and environmental risks; (viii) 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; (ix) the failure of counterparties to perform their obligations under hedging instruments, including put option contracts; (x) our plans for improvements at our Nevada operations, including at Fire Creek, are not successful; (xi) our estimates for the fourth quarter results are inaccurate; (xii) we take a material impairment charge on our Nevada operations; and (xiii) we are unable to remain in compliance with all terms of the credit agreement in order to maintain continued access to the revolver. For a more detailed discussion of such risks and other factors, see the Company’s 2019 Form 10-K, filed on February 13, 2020, and Form 10-Q filed on May 7, 2020 with the Securities and Exchange Commission (SEC), as well as the Company’s other SEC filings. 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 presentation, 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.

(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 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 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- and nine-month periods ended September 30, 2020 and 2019.

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 measure 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 primary silver mining companies and aggregating Casa Berardi and Nevada Operations for comparison with 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 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 are not included as a by-product credit when calculating CashCost, 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.

(1) Excludes the discretionary portion of general and administrative costs for Greens Creek, Casa Berardi and corporate of $0.4 million, $0.4 million and $1.4 million, respectively, for the third quarter and first nine months of 2020. Also excludes estimated Q4 2020 discretionary general and administrative costs for Greens Creek, Casa Berardi and corporate of $0.2 million, $0.2 million, and $0.9 million respectively.

(2) Includes all direct and indirect operating costs related to the physical activities of producing metals, including mining, processing and other plant costs, third-party refining and marketing expense, non-discretionary on-site general and administrative costs, royalties and mining production taxes, before by-product revenues earned from all metals other than the primary metal produced at each unit. AISC, Before By-product Credits also includes on-site exploration, reclamation, and sustaining capital costs.

(3) The unionized employees at Lucky Friday were on strike from March 2017 until January 2020, and production at Lucky Friday has been limited since the start of the strike. Costs related to ramp-up activities totaling $5.4 million in the first nine months of 2020, and suspension-related costs totaling $5.7 million during the strike in the first half of 2019, along with $6.3 million and $3.1 million, respectively, in non-cash depreciation expense for those periods, have been excluded from the calculations of cost of sales and other direct production costs and depreciation, depletion and amortization, Cash Cost, Before By-product Credits, Cash Cost, After By-product Credits, AISC, Before By-product Credits, and AISC, After By-product Credits.

(4) In early April 2020, the Government of Mexico issued an order to the mining industry to reduce operations to a minimum level until April 30 in response to COVID-19, and the order was subsequently extended until May 30. Our operations at San Sebastian were suspended during that time. Suspension-related costs totaling $1.1 million for the first nine months of 2020 are reported in a separate line item on our consolidated statements of operations and excluded from the calculations of cost of sales and other direct production costs and depreciation, depletion and amortization, mining and milling cost per ton, and Cash Cost and AISC, After By-product Credits, per Gold Ounce.

(5) AISC, Before By-product Credits for our consolidated silver properties includes non-discretionary corporate costs for general and administrative expense, exploration and sustaining capital.

(6) In late March 2020, the Government of Quebec ordered the mining industry to reduce to minimum operations as part of the fight against COVID-19, causing us to suspend our Casa Berardi operations from March 24 until April 15, when mining operations resumed, resulting in reduced mill throughput. Suspension-related costs totaling $1.6 million for the first nine months of 2020 are reported in a separate line item on our consolidated statements of operations and excluded from the calculations of cost of sales and other direct production costs and depreciation, depletion and amortization and Cash Cost and AISC, After By-product Credits, per Gold Ounce.

(7) Production was suspended at the Hollister mine in the third quarter of 2019 and at the Midas mine and Aurora mill in late-2019. Suspension-related costs at Hollister, Midas and Aurora totaling $9.6 million for the first nine months of 2020 are reported in a separate line item on our consolidated statements of operations and excluded from the calculations of cost of sales and other direct production costs and depreciation, depletion and amortization and Cash Cost and AISC, After By-product Credits, per Gold Ounce. During the third quarter of 2020, all ore mined at Nevada Operations was stockpiled, with no ore milled and no production reported during the period. As a result, costs incurred at Nevada Operations during the third quarter of 2020 were excluded from the calculations of Cash Cost and AISC, After By-product Credits, per Gold Ounce.

Reconciliation of Net Income (Loss) Applicable to Common Shareholders (GAAP) to Adjusted Net Income (Loss) Applicable to Common Stockholders (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 Income (Loss) (GAAP) to Adjusted EBITDA (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. Adjusted EBITDA is calculated as net income (loss) before the following items: interest expense, income tax provision, depreciation, depletion, and amortization expense, acquisition costs, foreign exchange gains and losses, unrealized gains and losses on derivative contracts, ramp-up and suspension income and costs, provisional price gains and losses, stock-based compensation, unrealized gains and losses on investments, provisions for closed operations, Foundation grant expense and interest and other income (expense). Management believes that, when presented in conjunction with comparable GAAP measures, Adjusted EBITDA is useful to investors in evaluating our operating performance. The following table reconciles net income (loss) to Adjusted EBITDA:
