Cash Flow from Continuing Operations up 61% Year-Over-Year to $175 million; Free Cash Flow¹ More Than Doubles Year-Over-Year to $136 million; Strongest balance sheet in Company's history; Lucky Friday sets new production record

Hecla Mining Company ((HL) ("Hecla", or the "Company") today announced second quarter 2026 financial and operating results. "Prior quarter" refers to the first quarter of 2026. Prior period financial information has been recast to reflect Casa Berardi as a discontinued operation.

SECOND QUARTER 2026 HIGHLIGHTS

Financial Performance:

Revenue: $334 million, an expected pullback from a record prior quarter, primarily reflecting lower realized silver and gold prices, in line with the trend of lower market prices during the quarter. Consolidated silver and gold production was higher than the prior quarter; the softer sales volumes reflect the timing of shipments, mainly at Greens Creek.
Profitability: Income from continuing operations of $118 million or $0.18 per share - down from $165 million or $0.25 per share in the prior quarter.
Adjusted EBITDA: $199 million from continuing operations, a 25% decrease over the prior quarter but more than double the $93 million recorded in the second quarter of 2025 (both periods on a continuing operations basis, excluding Casa Berardi).⁴
Continued strong cash flow generation: $175 million cash generated from continuing operations, and second best quarterly free cash flow from continuing operations of $136 million, with all producing assets contributing and Greens Creek and Lucky Friday setting new quarterly site-level free cash flow records.¹
Building balance sheet strength: Cash position of $483 million underscores continued balance sheet strengthening and strategic flexibility. With the redemption of the remaining $263 million in 7.25% Senior Notes ("Senior Notes"), the Company ends the second quarter debt free (excluding financial leases) and backed by a fully undrawn $225 million revolving credit facility, with $3.5 million of availability utilized for outstanding letters of credit, plus a $75 million undrawn accordion option, representing the strongest balance sheet position in the Company's history.

Operational Performance:

Operations:
- Silver production from continuing operations of 4.2 million ounces, up 8% from the prior quarter.
- Consolidated costs applicable to sales from continuing operations of $117 million, down 6% from the prior quarter. Silver cash cost of ($8.10) per ounce and AISC of $6.07 per ounce (both after by-product credits and excluding Keno Hill, which has not yet achieved commercial production).^2,3,5
- Safety: Consolidated TRIFR of 1.57, down from 2.07 in the prior quarter.
- Production and cost guidance: Consolidated silver production is expected to be 15.1-16.1 million ounces revised from 15.1-16.5 million ounces, with lower Keno outlook partly offset by improved outlooks for Greens Creek and Lucky Friday. Consolidated silver cash cost and AISC guidance lowered on outperformance in 1H26 compared to plan.^2,3See Guidance section for more details.
Individual Mine Performance:
- Greens Creek: Produced nearly 2.1 million ounces of silver and over 14 thousand ounces of gold. Costs applicable to sales of $50 million, with silver cash cost of ($17.11) per ounce and AISC of ($10.71) per ounce (both after by-product credits).^2,3,5
- Lucky Friday: Record silver production of 1.5 million ounces. Costs applicable to sales of $35 million, with silver cash cost of $3.95 per ounce and AISC of $17.08 per ounce (both after by-product credits).^2,3,5The surface cooling project is 88% complete and remains on track for completion in September.
- Keno Hill: Produced 0.6 million ounces of silver in the second quarter after working through a lower-grade zone. Subsequent to quarter end, the Company received authorization for construction of the Phase 2 West extension of its dry stack tailings facility.
- Growth pipeline: Preliminary work on the Greens Creek pyrite concentrate circuit points to potential for incremental annual production of approximately 1.0 to 1.2 million ounces of silver and 10,000 to 15,000 ounces of gold once fully ramped up. Separately, the Greens Creek dry-stack tailings facility currently holds an estimated 51 million ounces of silver and 600 thousand ounces of gold. 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" section below for further details.
- Exploration: As previously announced on July 29, 2026, drilling extended the high-grade Bermingham Deep trend at Keno Hill toward the historic Hector-Calumet Mine - a past-producer of approximately 96 million ounces of silver - now traceable over 800 feet of strike length. Separately, new high-grade vein discoveries were made at Midas in Nevada.

Rob Krcmarov, President and Chief Executive Officer, said: "Our second quarter results reflect the strength of the platform we have built. We ended the quarter with the strongest balance sheet in the Company's history, and Lucky Friday delivered record quarterly silver production, underscoring the quality of our silver portfolio. I'm also encouraged by our strong safety performance across the operations, which remains a foundation of everything we do. At the same time, our organic project pipeline continues to advance, demonstrating real potential for meaningful value creation and further solidify Hecla's position as North America's premier silver producer."

SECOND QUARTER RESULTS

Sales of $334 million decreased 19% compared to the prior quarter, primarily reflecting lower realized precious metals prices, due largely to timing of sales, a declining price environment and lower precious metals sales volumes. Payable silver sold was roughly 5% lower compared to the prior quarter, primarily driven by the timing of sales at Greens Creek.

Income from continuing operations was $118 million, or $0.18 per share compared to the record $165 million in the prior quarter (in each case from continuing operations, excluding Casa Berardi). The decline was primarily related to:

A 19% decrease in revenue from continuing operations for the items noted above
A $7 million increase in exploration and pre-development expense, primarily related to the seasonal increase in exploration activities across the portfolio
A $3 million increase in depreciation expense due primarily to higher production and sales volumes at Lucky Friday and Keno Hill

Partly offset by:

A $32 million decrease in tax expense primarily related to lower profitability compared to the prior quarter and tax planning strategies allowing for consolidation of tax groups
A $7 million decrease in costs applicable to sales primarily related to lower consolidated volumes of silver sold⁵
A $3 million decrease in interest expense primarily related to the repayment of the Senior Notes

Adjusted EBITDA from continuing operations was $199 million, down 25% from the prior quarter (in each period, excluding Casa Berardi), primarily reflecting the decrease in revenue, partly offset by lower costs applicable to sales.^4,5

Cash and cash equivalents at June 30, 2026, of $483 million, with no draws on the revolving credit facility, with $3.5 million of availability utilized for outstanding letters of credit.

Cash provided by operating activities from continuing operations was $175 million, down 4% from the prior quarter, primarily due to lower realized metal prices for silver, gold and lead, and lower volumes of payable silver and gold ounces sold, partly offset by a higher realized zinc price (in each period, excluding Casa Berardi). Cash provided by operating activities was positively impacted by a $63 million decrease in accounts receivable, driven by timing of concentrate shipments, the collection of receivables and lower metal prices reducing the value of concentrate receivables as of June 30, 2026.

Capital investment in continuing operations was $39 million, nearly unchanged from the prior quarter (in each period, excluding Casa Berardi). Capital investment is expected to increase in the third quarter and remain elevated in the fourth quarter, as projects across the portfolio advance through the warmer-weather construction season and into the fall. The Company continues to invest in 2026 corporate initiatives to strengthen planning discipline and operational efficiency.

Free cash flow from continuing operations was $136 million, compared to a record $144 million in the prior quarter, with the 5% decrease primarily due to lower cash flow from operations (in each period, excluding Casa Berardi).¹Greens Creek and Lucky Friday set new quarterly site-level free cash flow records of $130 million and $88 million, respectively.¹

^(a) Precious metals concentrates include intersegment sales to Greens Creek.

Consolidated silver production from continuing operations was 4.2 million ounces, up 8% from the prior quarter. The increase was driven by Lucky Friday's new quarterly record of 1.5 million ounces, benefiting from a 31% higher milled grade, a level consistent with plan, but not expected to be sustained, partly offset by 6% lower tons milled. Production also increased 28% at Keno Hill, as milling rates rose 38%, partly offset by 7% lower milled grade.

Gold production from Greens Creek was 14 thousand ounces, up 10% from the prior quarter due to 4% higher mill throughput and a higher grade milled.

Silver payable ounces sold of 3.4 million ounces, down 5% from the prior quarter, primarily due to lower payable ounces sold at Greens Creek and Keno Hill, partly offset by higher sales at Lucky Friday.

Gold payable ounces sold of 10 thousand ounces, down 12% from the prior quarter due to the timing of sales at Greens Creek.

Concentrate volumes produced and sold were higher at Lucky Friday and Keno Hill compared to the prior quarter. At Greens Creek, concentrate production was higher for one of the three concentrates produced, while concentrate sales were lower across all three, reflecting a lag between production and shipment: zinc and precious metals concentrate sales roughly matched production, while silver concentrate shipments lagged production, resulting in a build-up of silver concentrate inventory at quarter end that was shipped in early August. Concentrates sales at Lucky Friday were broadly in line with production in the second quarter. At Keno Hill, silver and zinc concentrate sales were below production volumes due to timing of sales, despite overall concentrate production and sales being higher than the prior quarter.

Consolidated silver costs applicable to sales (excludes depreciation) from continuing operations improved 6% over the prior quarter to $117 million, primarily due to lower volumes of silver sold.⁵

Silver cash costs and AISC per silver ounce from continuing operations, each after by-product credits and excluding Keno Hill, which has not yet achieved commercial production, were ($8.10) and $6.07, respectively, lower than the prior quarter, primarily due to higher ounces produced and $6 million higher by-product credits, mostly associated with higher volumes, partly offset by $2 million higher treatment charges. The decrease in AISC compared to the prior quarter reflects these same cash cost drivers, along with $1 million lower general and administrative expense, offset by $11 million higher sustaining capital investment, split roughly evenly between Lucky Friday and Greens Creek.^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 increased for Greens Creek, tightened up for Lucky Friday, and reduced for Keno Hill. There is no change to Greens Creek gold production guidance. Total silver cash costs and AISC per ounce (after by-product credits)^3,4 guidance is lowered on better than planned 1H26 results, and the lower end of total capital investment guidance is raised by about 2%.

2026 Production Outlook

Consolidated silver production is expected to be 15.1-16.1 million ounces, a lower upper end compared to prior guidance.

Greens Creek's silver production is expected to be 8.0-8.3 million ounces, raised up from the prior guidance of 7.5-8.1 million ounces.
Lucky Friday's silver production is expected to be 4.9-5.2 million ounces, tightened up from the prior 4.7-5.2 million ounces.
Keno Hill's silver production is expected to be 2.2-2.6 million ounces, lowered from the prior 2.9-3.2 million ounces. The Company's plan at Keno Hill is to run the operation at a sustained, more modest rate, while permitting and infrastructure build-out is prioritized, as previously disclosed.

Greens Creek's gold production guidance of 51.0-55.0 koz is reiterated.

2026 Cost Guidance Revised Lower

Total silver cash cost and AISC guidance per silver ounce (after by-product credits) is improved to ($4.00)-($3.75)/oz and $12.50-$13.50/oz respectively.^2,3 This guidance only incorporates Greens Creek and Lucky Friday, as Keno Hill remains in a state of pre-commercial production.

At Greens Creek, guidance for costs applicable to sales (excludes depreciation) at $240 million. Cash cost per silver ounce (after by-product credits) and AISC per silver ounce (after by-product credits) guidance is lowered to ($12.50)-($12.00) and ($4.25)-($3.75) respectively from ($9.00)-($8.25) and $0.00-$0.50 respectively.^2,3,5
At Lucky Friday, guidance for costs applicable to sales (excludes depreciation) of $139 million. Cash cost guidance is lowered to $9.00-$9.75 from the prior $10.25-$11.00 (after by-product credits), per silver ounce, and the lower end of AISC raised to $24.50-$26.00 from $23.50-$26.00 (after by-product credits), per silver ounce to reflect the higher sustaining capital investment guidance at the mine.^2,3,5

2026 Capital and Exploration

Lower end of total capital (growth and sustaining) investment guidance raised, top end reiterated, now at $208-$223 million from $204-$223 million.

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 expected to be completed by September and to increase the designed 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 remain unchanged and are expected to be $55 million, with the focus at Greens Creek and Keno Hill, Nevada and Lucky Friday.

Metal Prices and FX rate assumptions for 2H26 (1H26 actuals). Expectations for gold $4,000/oz, silver $55.00/oz, zinc $1.40/lb, lead $0.85/lb and copper $4.00/lb, for byproduct credit calculations. Numbers are rounded. Assumed exchange rate for Canadian dollar is unchanged at 1.35 CAD/USD.

PROJECT PIPELINE UPDATE

Hecla remains focused on advancing a pipeline of organic growth opportunities that build on existing infrastructure, established permitting paths, and the Company's deep operational expertise. The projects outlined below are anticipated to be low-capital-intensity opportunities with the potential to meaningfully expanding precious metal output, cash flows and net asset value over time, while avoiding 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 robust return on capital meeting Company thresholds, while potentially also reducing the rate of tailings deposited into the tailing storage facility, which would be expected to lower future tailings-related capital investment.

This work is at a preliminary economic assessment level of engineering, incorporating some advanced design (equivalent to an AACE Class 4 cost estimate advancing toward Class 3). Given the projected favorable benefit-to-cost ratio and low technical risk, the project is well suited to an accelerated engineering and execution path subject to receipt of applicable permits, and final investment approval. The Company currently targets first production between the fourth quarter of 2027 and the first half of 2028, with a ramp-up period of approximately one year required to reach full capacity. A dedicated internal project manager has been assigned to oversee execution, consistent with Hecla's approach to advancing near-term growth opportunities.

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, market conditions, and other factors described under "Cautionary Statement Regarding Forward-Looking Statements, Including 2026 Outlook" in this news release and under "Risk Factors" in the Company's 2025 Form 10-K filed on February 17, 2026, and Form 10-Q expected to be filed on August 4, 2026, as well as in other reports filed by the Company from time to time with the Securities and Exchange Commission. References to preliminary economic assessment, prefeasibility, and feasibility levels in this section describe the engineering and cost-estimate maturity of processing circuit design work and are not technical reports, preliminary economic assessments, or feasibility studies as those terms are defined under SEC Regulation S-K 1300 or 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. The project 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 testing scheduled for completion in August 2026. This next 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 positive results, it is expected the project would advance through a prefeasibility study 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 the early stages of testing and 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 liability.

At June 30, 2026, the dry-stack tailings facility at Greens Creek held an estimated 10.6 million tons of material, containing roughly 51 million ounces of silver, nearly 600 thousand ounces of gold, and additional critical minerals, representing a combined estimated in-situ gross metal value of approximately $6.1 billion (based on June 30, 2026 metals prices and before transportation, processing or sales costs, which are expected to be significant).

Midas Restart Project

Hecla continues to evaluate the potential to restart the existing, permitted Midas mill in northern Nevada, a historic high-grade gold and silver operation. Midas benefits from fully permitted infrastructure, which could help reduce the capital required for restart, 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 and 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 with a heavy focus on the Sinter Offset Zone and the Pogo target. The nearby Hollister high-grade gold and silver project is within trucking distance of the Midas mill and drilling has recently resumed after a multi-year pause. With multiple veins and trends still open along strike and at depth, and programs at Hollister and Aurora beginning, the Company expects continued exploration momentum through the second half of 2026 and aims to provide regular exploration updates for the Nevada exploration projects throughout 2026.

EXPLORATION AND PRE-DEVELOPMENT

Investment and Strategy

During the second quarter, the Company invested $11.3 million in exploration and corporate development (and $0.4 million in pre-development) activities, focused on high-impact discovery drilling at Keno Hill in Yukon and Midas in Nevada, and resource expansion programs at the Company's producing assets. This strategy balances district-scale discovery with near-mine resource definition and reserve extension. Guidance for 2026 remains at $55 million investment in exploration and pre-development. See our exploration update news release from July 29, 2026 for detailed results.

DIVIDENDS

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 investment, 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, net of finance leases.

⁽²⁾ Cash cost, after by-product credits, 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 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.

⁽³⁾ All-in sustaining cost ("AISC"), after by-product credits, 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, after by-product credits, includes costs applicable to 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.

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. 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.

Cautionary Statements to Investors on Reserves and Resources

This news release uses the terms "mineral resources", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources." Mineral resources that are not mineral reserves do not have demonstrated economic viability. You should not assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. Further, inferred mineral resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically, and an inferred mineral resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve. The Company reports reserves and resources under the SEC’s mining disclosure rules ("S-K 1300") and Canada’s National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") because the Company is a "reporting issuer" under Canadian securities laws. Unless otherwise indicated, all resource and reserve estimates contained in this press release have been prepared in accordance with S-K 1300 as well as NI 43-101.
