Insights

Hecla's Q3 2024 results show mixed performance with some concerning trends. Revenue of $245.1 million was the second-highest in company history, but net income of just $1.6 million reflects significant operational challenges. The 45% revenue contribution from silver demonstrates strong precious metals focus, while debt reduction of $50.6 million shows commitment to strengthening the balance sheet.

Key concerns include increased costs, with silver AISC rising to $15.29 per ounce from $12.54 in Q2 and production challenges at Keno Hill due to tailings facility delays. The $14.5 million write-down of mining equipment signals potential operational strategy shifts.

However, strong free cash flow generation at core assets (Greens Creek: $46.9 million, Lucky Friday: $23.2 million) and improved net leverage ratio of 1.8x provide financial stability.

The operational metrics reveal significant challenges. Silver production declined to 3.6 million ounces from 4.4 million in Q2, with Greens Creek facing unplanned maintenance and Keno Hill struggling with throughput issues. The reduction in 2024 silver production guidance coupled with increased cost guidance is concerning.

However, Lucky Friday's achievement of second-highest mill throughput in 80 years demonstrates operational capabilities. The exploration results, particularly at Keno Hill (63.8 oz/ton silver over 10.2 feet) and Greens Creek (74.0 oz/ton silver over 33.8 feet), indicate strong resource potential.

The transition to a new CEO and operational strategy adjustments, including abandoning the remote vein miner technology, suggest a period of strategic realignment ahead.

Exploration

At Keno Hill, over 9,800 feet of definition drilling was completed. Drilling continues to intersect high-grade silver mineralization over significant widths and highlights the potential for high-grade silver mineralization in the district. Highlights include:
- Bermingham Footwall Vein: 63.8 oz/ton silver, 6.7% lead, and 6.4% zinc over 10.2 feet
  - Includes: 99.6 oz/ton silver, 10.7% lead, and 9.8% zinc over 6.4 feet
Flame & Moth Vein 1: 71.6 oz/ton silver, 11.6% lead, and 11.2% zinc over 14.8 feet
At Greens Creek, over 27,000 feet of drilling was completed, focused on resource conversion and extension of mineralization. Highlights include:
- 200 South Zone: 74.0 oz/ton silver, 0.03 oz/ton gold, 4.7% zinc, and 2.2% lead over 33.8 feet
- Southwest Bench: 51.4 oz/ton silver, 0.52 oz/ton gold, 9.3% zinc, and 4.9% lead over 19.0 feet

"Hecla produced 3.6 million ounces of silver in the third quarter, bringing year-to-date production to 12.3 million ounces. Lucky Friday had a strong quarter as the mill achieved the second-highest throughput in its 80-year history after a record last quarter," said Cassie Boggs, Interim President and CEO. "While Greens Creek’s silver production was lower than anticipated due to five days of unplanned mill maintenance in the third quarter, our team was able to complete the maintenance quickly and complete a portion of our fourth quarter scheduled maintenance simultaneously. Strong performance from our silver operations has generated free cash flow of $170 million year-to-date, which along with opportunistic use of our ATM program, has allowed us to substantially repay outstanding borrowings on our revolving credit facility, reducing total debt by $50.6 million.”

Boggs continued, “At Keno Hill, we have already mined more than 2.5 million ounces and produced 2.1 million ounces of silver this year, putting us on track to meet our production guidance for this year. We are prioritizing building the foundation for this operation's future to operate in Yukon successfully, which includes improving safety and environmental practices and, importantly, valuing the perspectives of the Yukon Government and the First Nation of Na-Cho Nyäk Dun, both of whom have important roles in permitting our improvements to infrastructure as well as our future operations.”

New President and CEO

Ms. Boggs continued, “What we are most excited about is welcoming our new President and CEO, Rob Krcmarov, a proven leader in the mining industry. His vision and expertise will be invaluable as we continue our journey toward growth, innovation and continuous improvement."

Mr. Krcmarov added, "Hecla has a remarkable legacy of operational excellence, innovation, and a strong commitment to responsible mining and sustainable practices. I am thrilled to be a part of this team and I look forward to contributing to the Company's continued growth and success."

Sales in the third quarter of $245.1 million were consistent with the prior quarter as lower sales volumes of silver, gold and lead, and lower realized prices for silver, zinc, lead were offset by higher sales volumes for zinc and higher realized prices for gold. The lower sales volumes stemmed from a combination of lower production and volumes sold at Lucky Friday and Casa Berardi (due to lower grades and lower mill throughput) and lower sales volumes at Keno Hill due to lower mill throughput attributable to delays in design and construction of the dry stack tailings facility ("DSTF"), including permitting delays following the heap leach failure at Victoria Gold's Eagle Gold mine. Sales of silver and zinc concentrate inventory built up at Greens Creek in the prior quarter partially offset lower sales volumes from other operations.

Gross profit increased by 15% to $59.3 million, primarily attributable to the lower cost of sales at Keno Hill and Casa Berardi partially offset by higher cost of sales at Greens Creek due to higher volumes of metals sold.

Net income applicable to common stockholders for the quarter was $1.6 million, a $26.1 million reduction from the prior quarter, primarily because of:

A non-cash write down of $14.5 million, $13.9 million related to the remote vein miner. The machine was determined to be obsolete due to the success of the Underhand Closed Bench mining method at Lucky Friday and the decision by the vendor to terminate the program and exit that line of business.
Ramp-up and suspension costs increased by $8.1 million to $13.7 million, reflecting the lower mill throughput at Keno Hill due to delays of the DSTF described above.
Foreign exchange loss of $3.2 million, compared to a gain of $2.7 million in the prior quarter, due to the appreciation of the Canadian dollar against the U.S. dollar.
Exploration and pre-development increased by $3.9 million, due to increased activity over the summer months.
Income and mining tax provision increased by $2.4 million to $11.5 million reflecting higher taxable income of our US operations compared to consolidated book income.

The above items were partly offset by:

General and administrative costs decreased by $4.3 million primarily due to costs related to the departure of the former CEO in the prior quarter.
Interest expense decreased by $1.6 million reflecting a decrease in the Company's borrowing on its revolving credit facility.

Consolidated silver total cost of sales in the third quarter increased by 8% to $132.7 million, reflecting a product inventory draw down at Greens Creek. Consolidated cash costs and AISC per silver ounce, each after by-product credits, were $4.46 and $15.29 respectivelyand only include costs of Greens Creek and Lucky Friday for the full quarter (commercial production has not been declared at Keno Hill). The increase in cash costs was primarily due to lower silver production and by-product credits (lower production for all metals except zinc and lower realized prices for all metals except gold).^3,4

Consolidated gold total cost of sales were $46.3 million, reflecting a decrease in sales at Casa Berardi. Cash costs and AISC per gold ounce, each after by-product credits, increased to $1,754 and $2,059, respectively, as lower production costs were offset by lower gold production, with AISC also impacted by higher planned capital investment in tailings construction.^3,4

Adjusted EBITDA for the quarter was $88.9 million, in line with the prior quarter (which was a record).⁵ The net leverage ratio improved to 1.8 times from 2.3 times in the prior quarter due to a reduction in total debt of $50.6 million as the Company decreased borrowings under its revolving credit facility. Cash and cash equivalents at the end of the quarter were $22.3 million and included $13.0 million drawn on the revolving credit facility. Borrowing on the revolving credit facility decreased by $49.0 million in the quarter as the Company utilized insurance proceeds and equity issuances under the At-The-Market ("ATM") program to reduce the drawn amount. At current price levels and expected production, the Company anticipates continuing to reduce borrowings on the revolving credit facility.

Cash provided by operating activities was $55.0 million and decreased by $23.7 million from the prior quarter due to a decrease in net income adjusted for non-cash items of $13.4 million and unfavorable working capital changes of $10.3 million.

Capital investment of $55.7 million increased by $5.3 million from the prior quarter. Capital investments at the operations were as follows (i) $11.5 million at Greens Creek related to development, mill projects including replacement of tails and concentrate filter presses, definition drilling, and equipment purchases, (ii) $18.6 million at Casa Berardi, primarily related to tailings construction activities, (iii) $11.2 million at Lucky Friday primarily related to equipment purchases, pre-production drilling, and development and (iv) $14.4 million at Keno Hill, primarily related to DSTF work, equipment purchases, and capital development.

Free cash flow for the quarter was negative $0.7 million, compared to $28.3 million in the prior quarter.² The decrease in free cash flow is primarily attributable to lower cash flow from operations and increased capital investment.

Forward Sales Contracts for Base Metals and Foreign Currency

The Company uses financially settled forward sales contracts to manage exposure to zinc and lead price changes in forecasted concentrate shipments. On September 30, 2024, the Company had contracts covering approximately 10% and 32% of the forecasted payable zinc and lead production, respectively, through 2026, at an average zinc price of $1.37 per pound and a lead price of $1.00 per pound.

The Company also manages Canadian dollar ("CAD") exposure through forward contracts. On September 30, 2024, the Company had hedged approximately 39% of forecasted Casa Berardi and Keno Hill CAD-denominated direct production costs through 2026 at an average CAD/USD rate of 1.33. The Company has also hedged approximately 15% of Casa Berardi and Keno Hill's projected CAD-denominated total capital expenditures through 2026 at 1.35.

Greens Creek produced 1.9 million ounces of silver, a decrease over the prior quarter, primarily due to lower grades and reduced mill throughput attributable to five days of unplanned maintenance on the Semi-Autogenous Grinding ("SAG") mill variable frequency drive (unplanned maintenance extended to two days in October). By-product metal production was lower for gold and lead due to lower mill throughput and lower grades, while zinc production was flat as higher grades offset the lower milled throughput. The mine added copper to its by-product metals as the silver concentrate now includes copper as a payable metal (copper has been produced at the mine for multiple years but previously was not a payable metal in concentrates).

Sales in the quarter were $116.6 million, a 22% increase due to higher quantities of payable metals sold (all metals) as silver and zinc concentrate inventory built up from the prior quarter was sold in the third quarter. Higher quantities of metals sold offset the lower realized prices for all metals except gold. Total cost of sales was $73.6 million, an increase of 30%, reflecting higher payable metals sold. Cash costs and AISC per silver ounce, each after by-product credits, were $0.93 and $7.04, respectively, and increased over the prior quarter as lower production costs were offset by lower silver production and lower by-product credits (lower production volumes and lower realized prices for all metals except gold).^3,4

Cash flow from operations was $54.1 million, a 25% increase, primarily due to higher gross profit. Capital investments were consistent with the prior quarter. Free cash flow for the quarter was $46.9 million, an increase of 40%, attributable to higher cash flow from operations.²

Lucky Friday produced 1.2 million ounces of silver, 9% lower than the prior quarter, due to 6% lower milled grades and 3% lower throughput. Mill throughput averaged 1,133 tpd, the second highest in the mine's history after a record in the prior quarter.

Sales in the third quarter were $51.1 million, 14% lower due to lower volumes of metals sold and lower realized prices. Total cost of sales increased to $39.3 million, primarily due to higher production costs attributable to higher underground mobile equipment maintenance costs and higher contractor costs. Key mill projects, including installation of new cyclones, were completed during the quarter, contributing to lower mill throughput. Cash costs and AISC per silver ounce, each after by-product credits, were $9.98 and $19.40 respectively and were higher due to higher production costs and lower by-product credits (lower production and realized prices), and lower silver production.^3,4

Cash flow from operations was $34.4 million and decreased over the prior quarter due to lower gross margins realized and lower insurance proceeds of $14.8 million (prior quarter included $17.8 million in insurance proceeds). With $14.8 million in insurance proceeds received during the quarter, the Company has completed the claim after reaching the underground insurance sublimit of $50 million.

Capital investment for the quarter was $11.2 million, consistent with the prior quarter. Free cash flow for the quarter was $23.2 million, lower compared to the prior quarter primarily due to lower gross margins.²

*Revised for 2Q-2024, 1Q-2024 and 4Q-2023'

Keno Hill produced 597,293 ounces of silver at an average grade of 25.7 ounces per ton. Mined throughput averaged 343 tpd, milled tonnage averaged 261 tpd during the quarter, and 314 tpd during the nine months ended September 30, 2024. Lower mill throughput during the quarter was attributable to the delays in receiving an authorization for construction and a permit modification for the DSTF as the Yukon Government ("YG") and the First Nation of Na-Cho Nyäk Dun ("FNNND") initially focused on the Victoria Gold's Eagle Mine heap leach pad failure that occurred in June and not on permitting matters (Keno Hill does not utilize heap leach processing). Mill operations resumed on October 26, after receiving the authorization and modification and completing related design and construction work on the DSTF. The mine has produced 2.1 million ounces of silver for the nine months ended September 2024 and had an ore stockpile inventory of approximately 0.46 million silver ounces as of October 26, when the mill resumed processing.

Sales during the quarter were $19.8 million and declined over the prior quarter due to lower production and volumes sold. Total expenditures on production costs (excluding depreciation) were $25.0 million and include $10.0 million classified as ramp-up costs on the consolidated statement of operations. Capital investments during the quarter were $14.4 million. Due to the delays in permits, construction of the cemented tails batch plant, a critical infrastructure project, is now expected to be completed in the second quarter of 2025. The project is expected to facilitate the change in mining method at the Bermingham deposit to underhand mining, which should improve safety and productivity. Conversion to underhand mining is expected in the first half of 2026.

Following the Eagle Mine heap leach pad incident, the FNNND expressed strong positions on mining activities within their Traditional Territory, where Keno Hill is located, including a call to halt mining production. The Company values the perspectives of the YG and FNNND and is committed to sustainable and responsible mining that governments and local communities support. Further, in 2025, the Company's environmental remediation services group (which performs environmental remediation work in Yukon on behalf of the Canadian government) is also expected to increase construction activities, adding incremental demand on Keno Hill's infrastructure and resources. As a result of these stakeholder matters, the Company expects 2025 production to remain similar to 2024 and we expect to use this opportunity to advance permitting, invest in improving safety, environmental practices, and infrastructure, and prioritize stakeholder engagement. In 2026, after implementing these priorities, the Company expects production to increase beyond 2024 levels.

Casa Berardi produced 20,534 ounces of gold in the quarter, 11% less than the prior quarter due to lower underground grades. The mill operated at an average of 4,017 tpd during the quarter.

Sales were $50.3 million, a decrease of 14% over the prior quarter due to lower gold production and sales volumes were partially offset by higher realized gold price. Total cost of sales were $46.3 million, a decrease of 31% attributable to lower sales volumes and lower production costs. Cash costs and AISC per gold ounce, each after by-product credits, increased to $1,754 and $2,059, respectively, as lower gold production was partially offset by lower production costs, with AISC also impacted by higher planned capital investment on construction of tailings.^3,4

Cash flow from operations was $15.3 million, lower than the prior quarter primarily due to less gold ounces sold. Capital investments for the quarter totaled $18.6 million ($6.1 million in sustaining and $12.5 million in growth). Free cash flow for the quarter was negative $3.3 million, a decrease over the prior quarter attributable to lower cash flow from operations and higher planned capital investments.²

Casa Berardi is transitioning from a combined underground and surface operation to a surface only operation, which will require significant permitting and development activities. As a part of this transition, along with mining the 160 open pit, only the higher margin stopes of the west underground mine will be mined until they are exhausted, which is expected to occur in mid-2025. Casa Berardi is expected to produce gold from the 160 pit until 2027, and is expected to have a production gap commencing in 2027 and continuing until 2032 or later. During this time, the focus is expected to be on investing in infrastructure and equipment, permitting and de-watering and stripping two expected new open pits, Principal and West Mine Crown Pillar. Upon conclusion of the hiatus and related permitting and construction, the Company expects the mine to generate significant free cash flow at current gold prices. Given the expected hiatus in future production, the uncertainty surrounding permitting and timing of construction of the new open pits, and the Company’s newly hired President and CEO, the Company is evaluating the mine's fit into its overall strategy and is evaluating other potential strategic alternatives.

EXPLORATION AND PRE-DEVELOPMENT

Exploration and pre-development expenses totaled $10.6 million for the quarter. Exploration activities during the quarter primarily focused on underground definition and exploration drilling at Greens Creek and Keno Hill.

Keno Hill

Underground drilling during the thirdquarter continued to intersect high-grade silver mineralization over significant widths and highlights the potential for high-grade silver mineralization in the district. Underground definition drilling continued to be focused on extending mineralization and resource conversion in the high-grade Bermingham Bear Zone veins (Bear, Footwall, and Main Vein zones) and in the Flame & Moth veins. During the quarter, two underground drills completed over 9,800 feet of definition drilling.

Drilling in the Bermingham Mine Footwall vein has intersected significant silver mineralization over significant width in a portion of the Footwall vein where mineralization was modeled to be low-grade. Results from this drilling will increase the modeled grade in the western portion of the vein over 200 feet of strike length and 100 feet of dip length, and mineralization is open down dip for expansion. Drilling in the Flame and Moth Mine Vein 1 has also intersected significant silver mineralization over significant widths in a portion of Vein 1 where mineralization had previously not been modeled. These results will increase the modeled grade in the central portion of the vein over 230 feet of strike length and 100 feet of dip length. This mineralization remains open to the west for expansion.

Three surface drills were also active on the property testing multiple targets including the Bermingham Deep, Bermingham Townsite, Elsa17-Dixie, Silver Spoon, and Inca target areas that have potential for additional large high-grade silver deposits. Over 23,700 feet of surface exploration drilling in 10 drillholes were completed during the quarter. Wide spaced surface drilling in the Bermingham Deep target has demonstrated the presence of high-grade mineralization in the vicinity of an emergent highly prospective vein intersection target with additional drilling planned to confirm this vein intersection is controlling metal distribution and to expand drilling along plunge. In the Bermingham Townsite target, surface drilling has defined a zone of narrow high-grade mineralization located within 100 meters of the currently planned development and is open at depth along plunge for expansion.

Greens Creek

At Greens Creek, three underground drills completed over 27,000 feet of drilling focused on resource conversion and exploration to extend mineralization of known resources. Drilling was focused in the 9a, 200 South, 5250, West, Gallagher, and Upper Plate areas. In addition, two helicopter supported surface exploration drills completed over 8,000 feet of drilling expanding Upper Plate Zone mineralization 250 feet to the west of current resources and drill testing the Mammoth, Gallagher West, East Ore Offset, and Lower Zinc Creek targets.

Assay highlights include (reported widths are estimates of true width):

Upper Plate: 22.2 oz/ton silver, 0.02 oz/ton gold, 1.4% zinc, and 0.7% lead over 11.6 feet

2024 Cost Outlook

At Greens Creek, guidance for cash costs and AISC per silver ounce, each after by-product credits, has decreased to reflect higher by-product credits due to strong realized prices. At Lucky Friday, guidance for cash costs and AISC per silver ounce, each after by-product credits, has increased to reflect higher production costs and lower expected silver production.

At Keno Hill, guidance for expenditures on production costs, excluding depreciation, are unchanged and are expected to be $25-$27 million per quarter for the remainder of 2024. Casa Berardi's cash costs and AISC, each after by-product credits, are unchanged.

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 net income (loss) applicable to common stockholders is a non-GAAP measurement, a reconciliation of which to net income (loss) applicable to common stockholders, the most comparable GAAP measure, can be found at the end of the release. Adjusted net income (loss) applicable to common stockholders is a measure used by management to evaluate the Company's operating performance but should not be considered an alternative to net income (loss) applicable to common stockholders as defined by GAAP. They exclude certain impacts which are of a nature which we believe are not reflective of our underlying performance. Management believes that adjusted net income (loss) applicable to common stockholders per common share provides investors with the ability to better evaluate our underlying operating performance.

⁽²⁾Free cash flow is a non-GAAP measure calculated as cash provided by operating activities less capital expenditures. Cash provided by operating activities for the Greens Creek, Lucky Friday, Keno Hill, and Casa Berardi operating segments excludes exploration and pre-development expense, as it is a discretionary expenditure and not a component of the mines’ operating performance. Capital expenditures refers to Additions to properties, plants and equipment from the Consolidated Statements of Cash Flows, net of finance leases.

⁽³⁾ Cash cost, after by-product credits, per silver and gold ounce is a non-GAAP measurement, a reconciliation of total cost of sales, can be found at the end of the release. It is an important operating statistic that management utilizes to measure each mine's operating performance. It also allows the benchmarking of performance of each mine versus those of our competitors. As a primary silver mining company, management also uses the statistic on an aggregate basis - aggregating the Greens Creek and Lucky Friday mines to compare performance with that of other silver mining companies. Similarly, the statistic is useful in identifying acquisition and investment opportunities as it provides a common tool for measuring the financial performance of other mines with varying geologic, metallurgical and operating characteristics. In addition, the Company may use it when formulating performance goals and targets under its incentive program.

⁽⁴⁾ All-in sustaining cost (AISC), after by-product credits, is a non-GAAP measurement, a reconciliation of which to total cost of sales, the closest GAAP measurement, can be found in the end of the release. AISC, after by-product credits, includes total cost of sales and other direct production costs, expenses for reclamation at the mine sites and all site sustaining capital costs. AISC, after by-product credits, is calculated net of depreciation, depletion, and amortization and by-product credits. Prior year presentation has been adjusted to conform with current year presentation.

⁽⁵⁾ Adjusted EBITDA is a non-GAAP measurement, a reconciliation of which to net loss, the most comparable GAAP measure, can be found at the end of the release. Adjusted EBITDA is a measure used by management to evaluate the Company's operating performance but should not be considered an alternative to net loss, or cash provided by operating activities as those terms are defined by GAAP, and does not necessarily indicate whether cash flows will be sufficient to fund cash needs. In addition, the Company may use it when formulating performance goals and targets under its incentive program. 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.

⁽⁶⁾ Expectations for 2024 include silver, gold, lead, and zinc production from Greens Creek, Lucky Friday, Keno Hill, and Casa Berardi converted using gold $1,950/oz, silver $22.50/oz, zinc $1.20/lb, and lead $0.95/lb. Numbers are rounded.

Current GAAP measures used in the mining industry, such as total cost of goods sold, do not capture all the expenditures incurred to discover, develop and sustain silver and gold production. Management believes that AISC is a non-GAAP measure that provides additional information to management, investors and analysts to help (i) in the understanding of the economics of our operations and performance compared to other producers and (ii) in the transparency by better defining the total costs associated with production. Similarly, the statistic is useful in identifying acquisition and investment opportunities as it provides a common tool for measuring the financial performance of other mines with varying geologic, metallurgical and operating characteristics.

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. Words such as “may”, “will”, “should”, “expects”, “intends”, “projects”, “believes”, “estimates”, “targets”, “anticipates” and similar expressions are used to identify these forward-looking statements. Such forward-looking statements may include, without limitation: (i) at current price levels and expected production, the Company anticipates continuing to reduce borrowings on its credit facility; (ii) At Keno Hill, construction of cemented tails batch plant project is expected to 1) be completed in the second quarter of 2025, 2) improve safety and productivity at the Bermingham deposit, and 3) facilitate the change of mining method to underhand mining by the first half of 2026; (iii) also at Keno Hill, the Company expects 2025 production to remain similar to 2024 and to advance permitting and invest in improving safety, environmental practices, and infrastructure, and prioritizing stakeholder engagement in 2025, and that production is expected to increase beyond 2024 levels in 2026; (iv) Casa Berardi is expected to 1) continue underground production through mid-2025, 2) produce gold from the 160 pit until 2027, and 3) have a production gap commencing in 2027 to 2032 or later. During this time, the focus is expected to be on investing in infrastructure and equipment, permitting and de-watering and stripping two expected new open pits, Principal and West Mine Crown Pillar. Upon conclusion of the hiatus and related permitting and construction, the Company expects the mine to generate significant free cash flow, particularly at current gold prices; (v) projected total cost of sales, as well as cash cost and AISC per ounce (in each case after by-product credits) for Greens Creek, Lucky Friday, and Casa Berardi individually and for silver overall for 2024; (vi) Company-wide and mine-specific estimated spending on capital, exploration and predevelopment for 2024; and (vii) Company-wide and mine-specific estimated silver, gold, silver-equivalent and gold-equivalent ounces of production for 2024. 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 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) there being no significant changes to the availability of employees, vendors and equipment; (ix) 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; (x) counterparties performing their obligations under hedging instruments and put option contracts; (xi) sufficient workforce is available and trained to perform assigned tasks; (xii) weather patterns and rain/snowfall within normal seasonal ranges so as not to impact operations; (xiii) relations with interested parties, including First Nations and Native Americans, remain productive; (xiv) maintaining availability of water rights; (xv) factors do not arise that reduce available cash balances; and (xvi) there being no material increases in our current requirements to post or maintain reclamation and performance bonds or collateral related thereto.

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; and (vi) litigation, political, regulatory, labor and environmental risks. For a more detailed discussion of such risks and other factors, see the Company's 2023 Form 10-K filed on February 15, 2024, Form 10-Q filed on August 7, 2024 and Form 10-Q expected to be filed on November 7, 2024, for a more detailed discussion of factors that may impact expected future results. The Company undertakes no obligation and has no intention of updating forward-looking statements other than as may be required by law.

Non-GAAP Measures

(Unaudited)

Reconciliation of Total Cost of Sales to Cash Cost, Before By-product Credits and Cash Cost, After By-product Credits (non-GAAP) and All-In Sustaining Cost, Before By-product Credits and All-In Sustaining Cost, After By-product Credits (non-GAAP)

The tables below present reconciliations between the most comparable GAAP measure of total cost of sales 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 and for the Company for the three months ended September 30, 2024, June 30, 2024, March 31, 2024, December 31, 2023 and September 30, 2023 and the nine months ended September 30, 2024 and 2023.

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. We use AISC, After By-product Credits, per Ounce as a measure of our mines' net cash flow after costs for 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 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 silver and gold mining company, we also use these statistics on an aggregate basis - aggregating the Greens Creek and Lucky Friday mines to compare our performance with that of other silver 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 reclamation and sustaining capital costs. AISC, Before By-product Credits for our consolidated silver properties also includes corporate costs for general and administrative expense and sustaining capital costs. 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 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, their primary product, and by-product revenues earned from silver, which is a by-product at Casa Berardi. 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 unit is not included as a by-product credit when calculating Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce for the total of Greens Creek and Lucky Friday, our combined silver properties. Similarly, the silver produced at our other two units is not included as a by-product credit when calculating the gold metrics for Casa Berardi. We have not disclosed cost per ounce statistics for the Keno Hill operation as it is in the production ramp-up phase and has not met our definition of commercial production. Determination of when those criteria have been met requires the use of judgment, and our definition of commercial production may differ from that of other mining companies.

Reconciliation of Net Income (Loss) (GAAP) and Debt (GAAP) to Adjusted EBITDA (non-GAAP) and Net Debt (non-GAAP)

This release refers to the non-GAAP measures of adjusted earnings before interest, taxes, depreciation and amortization ("Adjusted EBITDA"), which is a measure of our operating performance, and net debt to adjusted EBITDA for the last 12 months (or "LTM adjusted EBITDA"), which is a measure of our ability to service our debt. Adjusted EBITDA is calculated as net income (loss) before the following items: interest expense, income and mining taxes, depreciation, depletion, and amortization expense, ramp-up and suspension costs, gains and losses on disposition of assets, foreign exchange gains and losses, write down of property, plant and equipment, fair value adjustments, net, interest and other income, provisions for environmental matters, stock-based compensation, provisional price gains and losses, monetization of zinc and lead hedges and inventory adjustments. 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 income (loss) and debt to adjusted EBITDA and net debt:

Reconciliation of Net Income (Loss) Applicable to Common Stockholders (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 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 property, plant and mine development. 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:

Dollars are in thousands	Three Months Ended						Nine Months Ended

Free cash flow	$	(690	)	$	28,298		$	(2,901	)	$	(86,650	)

Free cash flow is a non-GAAP measure calculated as cash provided by operating activities less additions to property, plant and mine development. Cash provided by operating activities for our silver operations, the Greens Creek and Lucky Friday operating segments, excludes exploration and pre-development expense, as it is a discretionary expenditure and not a component of the mines’ operating performance.
