1 Hecla Reports Third Quarter 2026 Results Cash Flow from Continuing Operations up 16% Quarter - Over - Quarter to record $203 million; Free Cash Flow 1 Nearly Triples Year - Over - Year to record $151 million COEUR D'ALENE, IDAHO - November 3, 2026 - Hecla Mining Company ( NYSE:HL ) ("Hecla", or the "Company") today announced third quarter 2026 financial and operating results. "Prior quarter" refers to the second quarter of 2026. Prior period financial information has been recast to reflect Casa Berardi as a discontinued operation. THIRD QUARTER 2026 HIGHLIGHTS Financial Performance: • Revenue: $395 million from continuing operations, the second highest in company's history. • Profitability: Income from continuing operations of $150 million or $0.22 per share - up from $118 million or $0.18 per share in the prior quarter. • Adjusted EBITDA: $211 million from continuing operations, a 6% increase over the prior quarter (both periods on a continuing operations basis, excluding Casa Berardi). 4 • Record cash flow generation: Cash flow generated from continuing operations of $203 million, and record quarterly free cash flow from continuing operations of $151 million; Greens Creek set a new site - level quarterly record of $147 million. 1 • Strengthening balance sheet: The Company ended the quarter with $692 million of cash and cash equivalents, reflecting continued balance sheet strength and strategic flexibility. The Company remains debt free (excluding finance leases) and has entered into a new $500 million revolving credit agreement with an additional $100 million a ccordion option. The facility is undrawn, with $3.4 million of capacity currently utilized for outstanding letters of credit. This is the strongest balance sheet position in the Company's history. Corporate Matters: • New Director: Mr. Dale Andres has joined the Board of Directors. Mr. Andres is a mining executive with over 35 years of experience in base and precious metals. Operational Performance: • Operations: o Safety: Consolidated TRIFR of 1.51, down from 1.57 in the prior quarter. o Silver production from continuing operations was 4.2 million ounces, nearly unchanged from the prior quarter, with consolidated silver sales volumes stronger, reflecting the timing of shipments, mainly at Greens Creek. o Consolidated costs applicable to sales from continuing operations of $158 million, up 35% from the prior quarter due primarily to the timing of sales. Silver cash cost remained negative at ($3.20) per ounce and AISC was $14.34 per ounce (excluding Keno Hill, which has not yet achieved commerci al production). Year - to - date AISC of $9.37/oz is essentially in line with $9.26/oz a year ago, and YTD cash cost improved to ($4.94)/oz from ($2.20)/oz. 2,3,5

2 o Production and cost guidance: Consolidated 2026 silver production is expected to be 15.3 - 16.1 million ounces, with low end raised compared to prior guidance of 15.1 - 16.1 million ounces. Consolidated silver cash cost and AISC guidance improved to ($4.75) - ($4.25)/oz and $11.50 - $12.50/oz respectively, 2,3 on outperformance during the first nine months of the year, reduced sustaining capital investment guidance, and higher by - product credits. 2,3 See Guidance section for more details. • Individual Mine Performance: o Greens Creek: Produced over 1.9 million ounces of silver and nearly 12 thousand ounces of gold. Costs applicable to sales were $76 million, with silver cash cost of ($10.11) per ounce and AISC of ($3.25) per ounce. 2,3,5 o Lucky Friday: Produced nearly 1.3 million ounces of silver. Costs applicable to sales were $34 million, with silver cash cost of $7.31 per ounce and AISC of $27.68 per ounce. 2,3,5 The surface cooling project is expected to commission in the fourth quarter. o Keno Hill: Produced nearly 1.0 million ounces of silver. Milled silver grade improved more than 35% from the prior quarter and milling rates reached a new quarterly record. Milling rates will be suppressed beginning in the fourth quarter to preserve the tailings stor age, waste rock and water treatment capacity available under current permits while license amendments are pursued (see "Keno Hill Update" below). o Growth pipeline: Preliminary work on the Greens Creek pyrite concentrate continues, and has led to a revision to growth capital expenditure guidance for Greens Creek. Subject to final investment approval, intermittent production using temporary equipment could begin in la te 2027 with potential to reach full capacity in late 2028, when construction of the new circuit is expected to be completed. Separately, the scope of the Greens Creek dry - stack tailings reprocessing evaluation has broadened to include two additional poten tial paths forward, or a combination of them. In Nevada, 2026 exploration investment guidance of $16 million is more than three times the 2025 level with expanded programs at Midas and new programs at Hollister and Aurora. See "Project Pipeline Update" sec tion below for further details. o Exploration: Exploration success continued in the third quarter, led by the discovery of a new mineralized extension at Keno Hill's Flame & Moth, 900 feet southwest of the existing resource; ongoing progress along the Bermingham trend toward the historic Hector - Calume t Mine; and massive sulfide intercepts at Greens Creek’s West Ore Offset target, with assays pending. Hecla also commenced drilling in Nevada at Aurora and Hollister and continued follow - up drilling on the new high - grade veins discovered at Midas in the se cond quarter. Rob Krcmarov, President and Chief Executive Officer, said: “Our third quarter results reflect the strength of the platform we have built, and we are well positioned to achieve our 2026 guidance. We generated record free cash flow of $151 million, led by Gr eens Creek's record $147 million. Our free cash flow generation and debt - free balance sheet provide us with the strongest financial position in our history, with nearly $700 million in cash and total liquidity of approximately $1.2 billion. Our organic pip eline continues to advance at Greens Creek, where preliminary work on the pyrite concentrate circuit is progressing and we are now evaluating two additional potential paths forward for the dry - stack tailings. These opportunities are still early stage, but they demonstrate the potential for meaningful value creation and to further solidify Hecla’s position as North America’s premier silver producer. We are delighted to welcome Dale Andres to our Board. We look forward to his insight and contributions as we c ontinue to grow Hecla."

4 Income from continuing operations was $150 million, or $0.22 per share compared to the $118 million in the prior quarter (in each case from continuing operations, excluding Casa Berardi). The increase was primarily related to:  An 18% increase in revenue from continuing operations for the items noted above  A $36 million increase in fair value adjustments, net, primarily due to realized and unrealized marketable securities gains Partly offset by:  A $41 million increase in costs applicable to sales primarily related to higher consolidated sales volumes of concentrates 5  A $22 million increase in tax expense primarily related to higher profitability compared to the prior quarter  A $6 million increase in exploration and pre - development expense, primarily related to the seasonal increase in exploration activities across the portfolio and the start up of programs at Hollister and Aurora in Nevada Adjusted EBITDA from continuing operations was $211 million, up 6% from the prior quarter (in each period, excluding Casa Berardi), primarily reflecting the increase in revenue, partly offset by higher costs applicable to sales and exploration and pre - development expense. 4,5 Cash and cash equivalents at September 30, 2026, of $692 million, up over 43% from the prior quarter. The increase reflects strong cash flow generation as well as $64 million of proceeds from the sale of investments. The Company's new $500 million credit facility remains undrawn, wit h $3.4 million of availability utilized for outstanding letters of credit. Record cash provided by operating activities from continuing operations was $203 million, up 16% from the prior quarter, primarily due to favorable working capital changes, higher volumes of payable silver and gold ounces sold and higher realized gold price, partly offset by a lower realized lead and zinc price (in each perio d, excluding Casa Berardi). Capital investment in continuing operations was $52 million, up 32% from the prior quarter (in each period, excluding Casa Berardi). Capital investment is expected to increase in the fourth quarter, as projects across the portfolio advance, including the planned completion of the dry stack tailings facility expansion at Keno Hill. Record free cash flow from continuing operations was $151 million, surpassing the previous all - time high of $144 million set in the first quarter of 2026, primarily due to higher cash flow from operations (in each period, excluding Casa Berardi). 1 Greens Creek set a new quarterly site - level free cash flow record of $147 million. 1

Consolidated silver production from continuing operations was 4.2 million ounces, nearly unchanged from the prior quarter. Production decreased 6% at Greens Creek and 17% at Lucky Friday, but these declines were offset by a 54% increase at Keno Hill which set a new quarterly record of nearly 1.0 million ounces. Keno Hill’s increase was driven by record tons milled of 38,163 and a 36% higher milled silver grade compared with the prior quarter. Greens Creek production declined from the prior quarter ma inly due to higher than planned maintenance during the quarter. Greens Creek plans to reduce mill availability in the fourth quarter for additional scheduled maintenance. As planned, Lucky Friday production declined as the mine moved out of a high - grade po cket of ore that drove a production record in the second quarter.

6 Gold production from Greens Creek was 12 thousand ounces, down 16% from the prior quarter due primarily to 5% lower mill throughput for the reasons noted above. Silver payable ounces sold of 4.1 million ounces, up 23% from the prior quarter, primarily due to higher payable ounces sold at Greens Creek and Keno Hill, partly offset by lower sales at Lucky Friday. Gold payable ounces sold of 13 thousand ounces, up 25% from the prior quarter due to the timing of sales at Greens Creek. Concentrate volumes produced and sold were higher at Keno Hill and for zinc concentrate at Lucky Friday compared to the prior quarter. At Greens Creek, concentrate production was lower for all three concentrates produced, while concentrate sales were higher for silver concentrate, compared to the prior quarter, reflecting the catch up in shipments: zinc and precious metals concentrate sales roughly matched production. Concentrates sales at Lucky Friday and Keno Hill were broadly in line wit h production in the third quarter. Consolidated silver costs applicable to sales (excludes depreciation) from continuing operations rose 35% over the prior quarter to $158 million, primarily due to higher sales volumes of silver, gold, lead and zinc. 5 Silver cash costs and AISC per silver ounce from continuing operations, excluding Keno Hill , which has not yet achieved commercial production, were ($3.20) and $14.34, respectively, higher than the prior quarter, primarily due to lower ounces produced at Greens Creek and Lucky Friday, $26 million higher costs applicable to sales (on higher sales volumes as noted above) and $14 million lower by - product credits compared to the prior quarter primarily due to lower gold production. This was partly offset by $4 million lower treatment charges ("TCs"). The increase in AISC compared to the prior quarter reflects these same cash cost drivers, along with $5 million higher sustaining capital investment, mostly attributable to Lucky Friday. 2,3 GUIDANCE In the tables below the Company provides production, cost, and capital guidance on a consolidated basis and by mine, as well as projected consolidated exploration and pre - development expenditures. Silver production guidance is unchanged for Greens Creek, t ightened up for Lucky Friday and for Keno Hill. There is no change to Greens Creek gold production guidance. Total silver cash costs and AISC per ounce 2,3 guidance is improved on better than expected results during the first nine months of 2026 and reduced sustaining capital investment guidance contributing to the improved AISC guidance. Total capital investment guidance is reduced by about 4%. 2026 Production Outlook Consolidated silver production is expected to be 15.3 - 16.1 million ounces, with low end raised compared to prior guidance of 15.1 - 16.1 million ounces, and Greens Creek's gold production guidance of 51.0 - 55.0 koz is reiterated.  Greens Creek's silver production is expected to be 8.0 - 8.3 million ounces, unchanged from prior guidance.  Lucky Friday's silver production is expected to be 5.0 - 5.2 million ounces, with low end raised from the prior 4.9 - 5.2 million ounces.  Keno Hill's silver production is expected to be 2.3 - 2.6 million ounces, with low end raised from the prior 2.2 - 2.6 million ounces.

7 Keno Hill Update In an attempt to maintain operational continuity, the Company is choosing to suppress Keno Hill mill throughput to approximately 300 tons per day in the fourth quarter of 2026 with further suppression, expected beginning in January 2027 to levels significantly below third quarter 2026 throughput. Including the Phase 2W dry - stack expansion, the Company estimates that approximately 200,000 tons of tailings storage capacity remains available under its current permits; how long that capacity lasts will depend on the rate at which ore is milled and the tailings generated per ton milled. The suppression is intended to preserve the tailings storage, waste rock and water treatment capacity available under our current permits while we pursue the license amendments needed to expand that capacity; it is not a cost - driven decision. We expect to hold the lower milling rate until those amendments are received, currently estimated by approximately mid - 2029, and the related infrastructure is built. We expect silver production to decline by proportionally less than throughput because, dur ing this period, we expect to be more selective in both mining and processing. In the mine, we will attempt to reduce dilution and prioritize higher - grade areas of the deposit. In the mill, we expect to preferentially process higher - grade material and stoc kpile lower - grade material for later processing. Actual production will depend on the grades, dilution, and recoveries we achieve. We expect to provide 2027 production guidance for Keno Hill in February 2027. See “Risk Factors” in the Company’s Form 10 - Q f or the quarter ended September 30, 2026. 2026 Cost Guidance Improved Total silver cash cost and AISC guidance per silver ounce is improved to ($4.75) - ($4.25)/oz and $11.50 - $12.50/oz respectively. 2,3 This guidance only incorporates Greens Creek and Lucky Friday, as Keno Hill has not yet reached commercial production.  At Greens Creek, guidance for costs applicable to sales (excludes depreciation) at $250 million, up $10 million from the prior guidance due mostly to actual results over the first nine months and higher expected power generation on site in the fourth quart er. Cash cost per silver ounce and AISC per silver ounce (guidance is improved to ($13.00) - ($12.50) and ($5.50) - ($5.00) respectively from ($12.50) - ($12.00) and ($4.25) - ($3.75) respectively. 2,3,5  At Lucky Friday, guidance for costs applicable to sales (excludes depreciation) of $140 million is reiterated. Cash cost guidance is improved to $8.50 - $9.00 from the prior $9.00 - $9.75, per silver ounce, and the higher end of AISC improved slightly to $24.50 - $25.50 from $24.50 - $26.00, per silver ounce to reflect better than expected results during the first nine months of 2026, with AISC guidance partly offset by the higher sustaining capital investment guidance at the mine. 2,3,5 2026 Capital and Exploration Investment Total capital (growth and sustaining) investment guidance lowered, now at $198 - $214 million from $208 - $223 million to reflect lower spend in the first nine months.  Greens Creek's capital investment is primarily attributable to mine development and the expansion of its tailings facility, which, when completed is expected to provide tailings storage capacity through 2045.  Lucky Friday's capital investment is heavily tied to underground development, a new tailings facility and a surface cooling project, which is now in a commissioning phase (subsequent to quarter end) with construction recently completed. The surface cooling project is designed to increase the cooling capacity at the mine to support its reserve mine - life of fifteen years.  Expected capital investment at Keno Hill comprises mine development, expansion of its tailings facility, and infrastructure projects. Exploration and pre - development expenditures, from continuing operations, remain unchanged and are expected to be $55 million, with the focus at Greens Creek and Keno Hill, Nevada and Lucky Friday.

The projects outlined below are anticipated to be low - capital - i ntensity opportunities with the potential to meaningfully expand precious metal output, cash flows and net asset value over time, while reducing many of the exploration and development risks inherent in greenfield projects. Greens Creek Pyrite Concentrate Circuit Greens Creek is advancing engineering and evaluation of a pyrite concentrate circuit which has the potential to recover additional silver and gold that currently report to tailings. Preliminary metallurgical and engineering work indicates the project could , at average reserve grades, add approximately 1.0 to 1.2 million ounces of silver and 10,000 to 15,000 ounces of gold in annual production, once fully ramped up. Preliminary cost estimates are underway. Early indications point to a potential return on capital exceeding Company thresholds, while potentially also reducing the rate of tailings deposited into the tailing storage facility, which would be expected to low er future tailings - related capital investment. This work is at a scoping level of engineering, incorporating some advanced design. Given preliminary indications of favorable benefit - to - cost ratio and perceived low technical risk, the project is well suited to an accelerated engineering and execution pa th subject to receipt of applicable permits, and final investment approval. Under that path, the Company expects to begin intermittent production of pyrite concentrate in late 2027 using temporary equipment, ahead of completing the new circuit, expected in late 2028. These estimates are preliminary, based on early - stage engineering and metallurgical work, and remain subject to change as the project advances. Actual results may differ materially from these estimates due to further technical work, permitting timelines, m arket conditions, and other factors described under "Cautionary Statement Regarding Forward - Looking Statements, Including 2026 Outlook" in this news release and under "Risk Factors"

The reference to scoping level of engineering in this section describes the engineering and cost - estimate maturity of processing circuit design work. It does not refer to an initial assessment, pre - feasibility study, feasibility study or technical report s ummary under SEC Regulation S - K 1300 or a preliminary economic assessment, pre - feasibility study, feasibility study or technical report under NI 43 - 101 in Canada. Greens Creek Tailings Reprocessing Project The Greens Creek tailings reprocessing project offers potential organic value creation, though significant groundwork is still needed before that value can be realized. Overall, the Company is evaluating three potential paths forward. The path with the gre atest amount of time invested to date, is at a preliminary, conceptual stage of engineering (equivalent to an AACE Class 5 to Class 4 cost estimate) and is progressing through a multi - phase metallurgical study conducted with a third party, with Phase 3 tes ting completed in August 2026 (metallurgical results pending). This third phase of multi - ton metallurgical work is a key milestone that should help shape next steps, with the potential to advance to a pilot plant test in Phase 4. If the tests yield positiv e results, it is expected the project would advance through further engineering and economic studies before any decision to execute. Early indications point to a potentially low capital intensity path for Hecla to achieve initial cash flows, though the project remains in early - stage testing and dep ends on the potential third - party partner securing a suitable processing facility. As an added benefit, reprocessing all or part of the existing tailings could decrease the space needed for tailings storage and help lower the mine's long - term reclamation l iability. The Company is also at an early stage of evaluating two additional pathways associated with the dry - stack tailings. The first is based on advances in processing technology and growing market demand for material like Greens Creek tailings, which has created the potential to turn material once managed only as tailings into a marketable low - grade feedstock. This potential project pathway could recover additional silver and gold currently contained in tailings material, subject to further metallurgical testing and the identification of a suitable third - party processing arrangement. In the fourth quarter, we expect to load a test parcel from Greens Creek of approximately 5,500 dry metric tonnes of low - grade feedstock for shipment and sale to a third party smelter. The second option is a potential self - processing pathway that would require an onsite processing facility that could require new or amended permits. The Company expects to begin metallurgical evaluation of the self - processing concept in the first quarter of 2027, with results from this testing potentially available by spring 2027 to help determine potential next steps. The Company expects to be able to provide further details on these options in coming quarters as evaluation work advances. Potenti al for the combination of two or more of these three options is also being evaluated. At September 30, 2026, the dry - stack tailings facility at Greens Creek held an estimated 10.7 million tons of material, containing roughly 51 million ounces of silver, nearly 600 thousand ounces of gold, and additional critical minerals, representing a com bined estimated in - situ gross metal value of approximately $6.4 billion (based on September 30, 2026 metals prices and before transportation, processing or sales costs, which are expected to be significant). This material is not a mineral resource or mineral reserve. Any recovery would depend on further testing, a suitable processing arrangement and favo rable economics. Midas Restart Project Hecla continues to evaluate the potential to restart the existing Midas mill in northern Nevada, a historic high - grade gold and silver operation. Midas benefits from existing permitted infrastructure, which could help reduce the capital required for restar t, and the Company is working to expand the existing high - grade gold and silver resource to the scale needed to support that restart. Midas represents a potential hub - and - spoke operating model, with ore potentially sourced from multiple regional deposits a nd fed into the 1,200 tpd mill. The site also includes an existing permitted tailings facility, offering approximately 15 years of storage capacity at the mill's nameplate capacity. The Company has allocated $16 million of the 2026 exploration budget for the Nevada project portfolio, more than three times the investment made in 2025. The 2026 drill program at Midas is focused on following up on the success of the 2025 drill program wi th a heavy focus on SE Pediment area that includes multiple targets

Page 10

10 including Sinter, Sinter Offset, and Pogo. The nearby Hollister high - grade gold and silver project is within trucking distance of the Midas mill and drilling resumed in the third quarter after a multi - year pause. With multiple veins and trends still open a long strike and at depth, and programs at Aurora and Hollister beginning in the third quarter, the Company expects continued exploration momentum through the fourth quarter of 2026 and aims to provide regular exploration updates for the Nevada exploration projects throughout the coming quarters. EXPLORATION AND PRE - DEVELOPMENT _____________________________________________________________________________________________________________ Investment and Strategy During the third quarter, the Company invested $16.6 million in exploration and corporate development (and $0.6 million in pre - development) activities, focused on high - impact discovery drilling at Keno Hill in Yukon and Midas, Aurora and Hollister in Nevad a, and resource expansion programs at the Company's producing assets. Year - to - date, the Company has invested $32.5 million in exploration and corporate development, with this strategy balancing district - scale discovery with near - mine resource definition an d reserve extension. Guidance for 2026 remains at $55 million investment in exploration and pre - development. Producing Asset Resource Definition Underground drilling at Greens Creek and Keno Hill continues to extend and upgrade mineralization near existing resource boundaries. The aim is to convert Inferred resources, the least certain category, into more certain categories and to identify reserve extensions. Greens Creek Three underground rigs continued drilling around existing resources, with results received from the 200S, East and SWB zones. Notable intercepts include:  200S Zone. 63.6 oz/ton silver, 0.01 oz/ton gold, 4.1% zinc and 1.9% lead over 14.1 feet.  200S Zone. 48.1 oz/ton silver, 0.11 oz/ton gold, 0.8% zinc and 0.4% lead over 15.9 feet.  East Zone. 6.4 oz/ton silver, 0.04 oz/ton gold, 25.4% zinc and 12.0% lead over 20.7 feet. Keno Hill One underground rig continued drilling in the Arctic Zone of the Bermingham mine. Notable intercepts on the Bermingham Main Vein include:  54.3 oz/ton silver, 7.4% zinc and 4.7% lead over 4.6 feet, which upgrades the resource.  24.8 oz/ton silver, 1.6% zinc and 1.9% lead over 5.0 feet, which expands the resource on the same vein. EXPLORATION PROGRAMS Keno Hill Exploration Exploration drilling at Keno Hill ramped up through the quarter after a period of reduced drilling capacity earlier in the year. The primary contractor returned its second and third drills to service in late July and late August, and a second contractor ad ded one drill at Flame & Moth in late July. Four drills are now operating and are expected to continue through the remainder of 2026. Flame & Moth, a new zone of high - grade silver Drilling has been successful in testing the favorable Basal Quartzite on strike with the Lightning vein. The zone has currently been defined over 350 feet of dip length and sits 900 feet southwest of the existing resource. Four holes tested the area and th ree found significant mineralization. Assays are back for two holes (Figure 1).  Hole K - 26 - 0944. 26.1 oz/ton silver and 14.0% zinc over 8.5 feet.  Hole K - 26 - 0951. 6.5 oz/ton silver and 3.5% zinc over 16.1 feet. The zone is open to the northeast, toward the existing resource, and to the southwest. Follow - up drilling will continue in the fourth quarter and into 2027.

Key results include 25.7 oz/ton silver and 4.2% lead over 10.0 feet (K - 26 - 0940) and 14.6 oz/ton silver over 5.2 feet (K - 26 - 0935B) in the Footwall Vein. The Ruby Vein returned 9.3 oz/ton silver over 15.8 feet (K - 26 - 0941). The subparallel Main Vein 2 returned 61.1 oz/ton silver and 3.8% lead over 5.3 feet and has been extended about 260 feet to the southwest. Together, the trend now spans about 1,300 feet, up 500 feet from Q2 , though that length relies on visual observations from two holes (K - 26 - 0942 and K - 26 - 0945) with assays still pending (Figure 2). The northeast extension points toward the historic Hector - Calumet Mine, where the company believes the two mineralizing system s may converge at depth, making it a major target for late 2026 and 2027.

12 Nevada Exploration Midas is the only Nevada property with results this quarter: hole DMC - 494 confirmed a second narrow high - grade gold vein (0.73 oz/ton gold and 2.9 oz/ton silver over 1.4 feet), and five follow - up holes all hit the expected structure, though only one has be en assayed so far. Midas remains in restart evaluation with no decision made, and the key question is whether the veins have enough continuity and grade to support a resource. At Aurora and Hollister, drilling has just begun and all assays are pending. Early holes at both found alteration and veining typical of gold - silver systems, which supports continued drilling, with remaining targets scheduled for Q4 and follow - up drilling in 2027. Detailed exploration drill assay highlights can be found in Table A at the end of this release.

ABOUT HECLA Founded in 1891, Hecla Mining Company (NYSE: HL) is the largest silver producer in the United States and Canada. In addition to operating mines in Alaska and Idaho, the Company is advancing its Keno Hill mine in the Yukon, Canada, and owns a number of expl oration and pre - development projects in world - class silver and gold mining districts throughout North America. 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) Free cash flow is a non - GAAP measure calculated as cash provided by operating activities less capital investment. Cash provided by operating activities for the Greens Creek, Lucky Friday, and Keno Hill operations excludes exploration and pre - development in vestment, as it is a discretionary expenditure and not a component of the mines’ operating performance. Capital investment refers to Additions to properties, plants and equipment from the Consolidated Statements of Cash Flows.

Page 13

13 (2) Cash cost per silver ounce is a non - GAAP measurement, a reconciliation of costs applicable to 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 al so 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 comm on 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”) is a non - GAAP measurement, a reconciliation of which to costs applicable to sales, the closest GAAP measurement, can be found in the end of the release. AISC includes costs applicable to sales and other direct production co sts, expenses for reclamation at the mine sites and all site sustaining capital costs. AISC is calculated net of depreciation, depletion, and amortization and by - product credits. Current GAAP measures used in the mining industry, such as total costs applicable to sales, 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 p rovides 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) Adjusted EBITDA is a non - GAAP measurement, a reconciliation of which to income from continuing operations, 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 income from continuing operations, 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. (5) Excludes depreciation, depletion and amortization.

20 Reconciliation of Costs Applicable to Sales to Cash Cost, Before By - product Credits (non - GAAP) and Cash Cost (non - GAAP) and All - In Sustaining Cost, Before By - product Credits (non - GAAP) and All - In Sustaining Cost (non - GAAP) The tables below present reconciliations between the most comparable GAAP measure of costs applicable to sales to the non - GAAP measures of (i) Cash Cost, Before By - product Credits, (ii) Cash Cost, (iii) AISC, Before By - product Credits and (iv) AISC for our operations and for the Company for the three and nine months ended September 30, 2026 and 2025, the three months ended June 30, 2026, March 31, 2026 and December 31, 2025. Cash Cost and AISC 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 n on - GAAP m easures as the Company reports them are the same as those reported by other mining companies. Cash Cost is an important operating statistic that the Company utilizes to measure each mine's operating performance. The Company uses AISC as a measure of our mines' net cash flow after costs for reclamation and sustaining capital. This is simila r to the Cash Cost non - GAAP measure the Company reports, but also includes reclamation and sustaining capital costs. Current GAAP measures used in the mining industry, such as costs applicable to sales, do not capture all the expenditures incurred to disc over, develop and sustain silver and gold production. Cash Cost and AISC 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 basi s - a ggregating 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 measu ring 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 r efining 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 structur e, distinguishing our silver operations due to the polymetallic nature of their orebodies. In addition to the uses described above, Cash Cost and AISC per Ounce provide management and investors an indication of operating cash flow, after consideration of the average price received from production. The Company also uses these measurements for the comparative monitoring of performance of our mining operations period - to - period from a cash flow pers pective.

24 Reconciliation of Income from Continuing Operations (GAAP) to Adjusted EBITDA from Continuing Operations (non - GAAP) This release refers to the non - GAAP measures of adjusted earnings before interest, taxes, depreciation and amortization ("Adjusted EBITDA") from continuing operations, which is a measure of our operating performance. Adjusted EBITDA from continuing operati ons is calculated as income from continuing operations 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, foreig n exchange gains and losses, write down of property, plant and equipment, fair value adjustments, net, interest and other income, provisions for closed operations and environmental matters, stock - based compensation, provisional price gains, monetization of zinc and lead hedges and inventory adjustments. Management believes that, when presented in conjunction with comparable GAAP measures, adjusted EBITDA is useful to investors in evaluating our operating performance and ability to meet our debt obligations. The following table reconciles income from continuing operations to adjusted EBITDA from continuing operations: Dollars are in thousands 3Q - 2026 2Q - 2026 1Q - 2026 4Q - 2025 3Q - 2025 LTM September 30, 2026 YTD 2025 Income from continuing operations $ 149,600 $ 117,876 $ 164,653 $ 110,059 $ 89,363 $ 542,188 $ 148,000 Interest expense 620 2,413 5,656 5,396 13,264 14,085 35,604 Income and mining tax provision 40,548 18,767 50,900 37,351 31,030 147,566 61,390 Depreciation, depletion and amortization 36,549 36,772 33,768 31,185 38,481 138,274 101,152 Care and maintenance 3,353 3,062 3,246 2,060 2,003 11,721 6,559 Loss on disposition of properties, plants, equipment, and mineral interests (5 ) 1,932 1,750 6 2,706 3,683 3,005 Foreign exchange loss (gain) 652 4,445 (498 ) 2,196 (436 ) 6,795 3,724 Fair value adjustments, net (26,691 ) 9,246 5,945 19,334 (19,828 ) 7,834 (27,666 ) Provisional price losses (gains) 7,029 7,089 (848 ) (28,993 ) (10,903 ) (15,723 ) (21,969 ) Provision for closed operations and environmental matters 4,017 1,329 1,297 4,965 1,268 11,608 2,902 Stock - based compensation 3,377 3,297 2,784 3,356 2,639 12,814 7,562 Inventory adjustments — — — 8,501 51 8,501 2,421 Other (7,575 ) (7,049 ) (3,549 ) 5,539 (2,501 ) (12,634 ) (5,286 ) Adjusted EBITDA from continuing operations $ 211,474 $ 199,179 $ 265,104 $ 200,955 $ 147,137 $ 876,712 $ 317,398 Reconciliation of Cash Provided by Operating Activities from Continuing Operations (GAAP) to Free Cash Flow from Continuing Operations (non - GAAP) This release refers to a non - GAAP measure of free cash flow from continuing operations, calculated as cash provided by operating activities from continuing operations, less capital investments.
