Current wording

Hecla Mining Company stands as North America's premier silver producer, with a rich heritage dating back to 1891. Our operations at Greens Creek, Lucky Friday and Keno Hill combined to produce 37% of 2025 silver production in the U.S. and Canada, complemented by significant gold production from Greens Creek and our former Casa Berardi operation. Our strategic positioning in the stable jurisdictions of the U.S. and Canada provides us with distinct operational advantages and reduced political risk compared to our global peers. Our operational and strategic framework centers on four core pillars:

Previous wording

Strong Production- We produced 4.6 million ounces of silver with increased silver production at all primary silver operations, compared to 3.6 million ounces of silver in the third quarter of 2024. We produced 40,654 ounces of gold, an increase over 32,280 ounces of gold produced in the third quarter of 2024, driven by higher grades and recoveries at Greens Creek and the continuation of underground mining at Casa Berardi.

Current wording

Production- We produced 3.9 million ounces of silver at our primary silver operations, compared to 4.1 million ounces of silver in the first quarter of 2025. At Greens Creek, we produced 12,886 ounces of gold, a decrease compared to 13,759 ounces of gold produced in the first quarter of 2025, driven primarily by lower throughput.

Previous wording

Revenue Generation - Generated record sales of $409.5 million, a 67% increase over the third quarter of 2024.

Current wording

Revenue Generation - Generated sales of $411.4 million, a 100% increase over the first quarter of 2025.

Our financial results vary as a result of fluctuations in market prices primarily for silver and gold and, to a lesser extent, zinc, lead and copper. World market prices for these commodities have fluctuated historically and are affected by numerous factors beyond our control. To date, tariffs have not materially impacted our financial results. However, future tariffs or other global trade restraints could impact our performance. Historically our US operations have had significant sales into China and Canada, and each of those countries is or could be subject to tariffs, and each has or may retaliate in kind. Notwithstanding these recent developments, we believe that the outlook for precious metals fundamentals is favorable due to macro-economic factors such as lower interest rate expectations, geopolitical uncertainty and global growth expectations, which have resulted in significant volatility in the financial and commodities markets, including the precious metals market. See Part II, Item 1A. “Risk Factors” of this Form 10-Q, Item 1A. “Risk Factors” contained in Part I of our 2024 Form 10-K, and Part II, Item 1A of our first and second quarter 2025 Form 10-Q for further discussion. Because we cannot control the price of our products, except to the extent we have entered into hedging transactions, the key measures that management focuses on in operating our business are production volumes, payable sales volumes, Cash Cost, After By-product Credits, per Ounce (non-GAAP) and All-In Sustaining Cost, After By-product Credits, per Ounce (“AISC”) (non-GAAP), operating cash flows, capital expenditures, free cash flow (non-GAAP) and adjusted EBITDA (non-GAAP). The average realized prices for all metals sold by us continued to exhibit significant volatility during the period. We have also experienced significant cost inflation across our operations, principally associated with higher energy prices, increased costs for other consumables such as reagents, explosives and steel, and higher labor and contractor costs.

Previous wording

Average realized prices typically differ from average market prices primarily because concentrate sales are generally recorded as revenues at the time of shipment at forward prices for the estimated month of settlement, which differ from average market prices. Due to the time elapsed between shipment of concentrates and final settlement with the customers, we must estimate the prices at which sales of our metals will be settled. Previously recorded sales are adjusted to estimated settlement metals prices each period through final settlement. We recorded net positive price adjustments to provisional settlements of $10.9 million and $5.0 million for the three months ended September 30, 2025 and 2024, and $22.0 million and $19.5 million for the nine months ended September 30, 2025 and 2024, respectively. The price adjustments related to silver, gold, zinc, lead and copper contained in our concentrate shipments were partially offset by gains and losses on forward contracts and collars for those metals. See Note 8 of Notes to Condensed Consolidated Financial Statements (Unaudited)for more information. The gains and losses on these contracts are included in revenues and impact the realized prices for silver, gold, lead, zinc and copper. Realized prices are calculated by dividing gross revenues for each metal (which include the price adjustments and gains and losses on the forward contracts discussed above) by the payable quantities of each metal included in concentrate, doré and carbon material shipped during the period.

We acquired our Keno Hill operation as part of the Alexco Resource Corp. acquisition in September 2022 and have focused on development activities and began ramp-up of the mill during the second quarter of 2023. The average mill throughput during the nine months ended September 30, 2025, was 307 tons per day (the mine is currently permitted to a maximum of an average of 440 tons per day), with silver grades milled of 30.0 ounces per ton. During the year, the mill has relied on existing ore stockpiles as the mine continues to focus on development and ramp up to higher tonnage rates with mining rates of 273 tons per day during the nine months ended September 30, 2025, with material sourced from both the Bermingham and Flame and Moth deposits. Mill throughput, while currently steady, has been negatively impacted by last year's events as described below.

Current wording

We acquired our Keno Hill operation as part of the Alexco Resource Corp. acquisition in September 2022 and have focused on development activities and began ramp-up of the mill during the second quarter of 2023. The average mill throughput during the three months ended March 31, 2026, was 276 tons per day (the mine is currently permitted to a maximum of an average of 440 tons per day), with silver grades milled of 20.8 ounces per ton. During the first three months of 2026, the mill has relied on existing ore stockpiles as the mine continues to focus on development and ramp up to higher tonnage rates with mining rates of 276 tons per day during the quarter, with material sourced from both the Bermingham and Flame and Moth deposits. Mill throughput, while currently steady, was negatively impacted in the first quarter by limited ore availability from the Bermingham deposit due to reduced output from the Bear zone and dilution control issues in narrow vein stopes caused by mining remnant areas as we depart that zone and transition into the Arctic zone, as well as by mine sequencing at the Flame and Moth deposit, which was altered as a result of power curtailments by Yukon Energy (the electric utility that supplies the Mine) lasting sixteen days in December 2025 and five days in January 2026 due to extreme cold weather. We expect these impacts to diminish throughout the remainder of the year.

Previous wording

From commencement of production until late August, 2024, ore production and mill throughput generally increased as planned, leading to increased levels of production (though still not reaching the permitted capacity at the mill). However, starting in mid-2024 and continuing today, Keno Hill has been impacted by external events which have affected permitting, projects and production, and delayed our ability to reach sustained, profitable production. In late June 2024, an unrelated, third party, Victoria Gold, experienced a heap leach failure at its Eagle Mine which is located near Keno Hill. This incident had several immediate and ongoing impacts on our operations. The primary impact was that we were forced to suspend milling operations at Keno Hill between August 27 and October 26, 2024 due to delays in receiving authorizations and permits because the focus of the Yukon Government (“YG”) and the First Nation of Na-Cho Nyäk Dun (“FNNND”) was on the Eagle Mine incident response and not on routine permitting matters. Mill operations and design and construction projects resumed during the fourth quarter of 2024. Our original planned schedule for permitting and projects has been extended, but we are taking steps, including working with regulators, to establish a viable schedule for our operational plans.

Current wording

From commencement of production until late August 2024, ore production and mill throughput generally increased as planned, resulting in higher production levels, although still below the mill’s permitted capacity. Beginning in mid‑2024 and continuing into 2025, however, Keno Hill was impacted by external events that affected permitting, projects and production, and delayed our ability to achieve sustained, profitable operations.

Previous wording

Then, starting in late October 2024, Keno Hill began experiencing power curtailments when the utility, Yukon Energy, experienced a turbine failure at its Aishihik hydroelectric plant in Whitehorse. That failure and Yukon Energy’s resulting focus on line maintenance, combined with cold temperatures in the Yukon (and the resulting increase in demand for power), caused Yukon Energy to reduce power to Keno Hill, resulting in the operation’s inability to fully power the mine and mill on several occasions in late 2024 and for 8 days in the first quarter of 2025. Temporary power constraints in the Yukon region impacted approximately 130,000 ounces of silver production and labor costs for idled employees of approximately $0.5 million through September 30, 2025. These conditions improved subsequent to the first quarter of 2025 when we experienced no power disruptions by Yukon Energy, and we do not expect any further disruptions as the hydroelectric plant turbine was successfully repaired in the third quarter.

Current wording

Beginning in late October 2024, Keno Hill experienced power curtailments after Yukon Energy suffered a turbine failure at its Aishihik hydroelectric plant in Whitehorse. This failure, combined with Yukon Energy’s focus on line maintenance and increased power demand due to cold winter temperatures, resulted in reduced power deliveries to Keno Hill and prevented us from fully powering the mine and mill on multiple occasions in late 2024 and the first quarter of 2025. These power constraints reduced silver production by approximately 130,000 ounces and resulted in approximately $0.5 million of labor costs for idled employees through September 30, 2025. Power conditions improved following the first quarter of 2025 and we do not expect additional curtailments due to the Aishihik turbine, which was successfully repaired in the third quarter of 2025. However, as mentioned above, we experienced power curtailments in the fourth quarter of 2025 and the first quarter of 2026. See the Risk Factor in our 2025 Form 10-K,"We may be subject to a number of unanticipated risks related to inadequate infrastructure."

Previous wording

Permitting is one of the most important factors in our ability to reach sustainable, profitable production at Keno Hill. Increased production means a need for increased tailings storage, waste storage, water treatment and discharge, camp space and reliable power, all of which are typical requirements for mines in the expansion phase. These projects require new or modified permits, as well as the capital to implement them. Although we continue to make progress on these normal-course permitting matters, we have yet to make up for the delays described above. In addition, as we develop new zones for ore production at Keno Hill (and our other mines), we are frequently confronted with challenging conditions such as rock quality and ground water volumes. Currently, we are developing new headings at Keno Hill to supplement existing, or replace mined out headings. At some of these new headings, we are encountering more groundwater than expected. The mine's water license has limits on the amount of water that can be discharged from the mine. Although we currently are within permitted water discharge limits, if production from these new zones would cause water discharges greater than the license allows we will need to make alternative arrangements, which likely includes seeking an amendment to our current water license. There can be no assurances that the Yukon Water Board will grant such an amendment. If we are unable to amend our license in a timely manner and we confirm that continued mining in these new zones would lead to discharges in excess of license limits, our options would then include curtailing production to remain within existing permitted discharge limits and/or developing a different operational plan to reduce discharges. Although we consider it unlikely, if none of these potential solutions is achieved, it is possible we would consider pausing production and other mining activities at the impacted areas and reassess our permitting strategy and other future operational aspects of the mine. See the Risk Factor in our 2024 Form 10-K"We are required to obtain governmental permits and other approvals in order to conduct mining operations."

Current wording

See the Risk Factor in our 2025 Form 10‑K, “We are required to obtain governmental permits and other approvals in order to conduct mining operations.”

During the three and nine months ended September 30, 2025, an income and mining tax provision of $54.9 million and $103.6 million, resulted in an effective tax rate of 35.3% and 35.6%, respectively. This compares to an income and mining tax provision of $11.5 million and $22.3 million, which resulted in an effective tax rate of 86.7% and 48.3%, respectively, for the three and nine months ended September 30, 2024. The comparability of our income and mining tax provision and effective tax rate for the reported periods was impacted by multiple factors, primarily: (i) mining taxes; (ii) variations in our income before income taxes; (iii) geographic distribution of that income; (iv) foreign exchange rates including non-recognition of foreign exchange gains and losses; (v) percentage depletion; and (vi) the non-recognition of tax assets. The effective tax rate will fluctuate, sometimes significantly, period to period. The change in the effective tax rate during the three and nine months ended September 30, 2025, compared to the comparable periods in 2024 is primarily related to the reported consolidated income as well as the losses incurred at our consolidated Alexco subsidiaries, and our Nevada subsidiaries, for which no tax benefit is recognized due to uncertainty surrounding our ability to utilize these future tax benefits.

We believe that our liquidity and capital resources from our continuing operations are adequate to fund our operations and corporate activities.

As a result of our current cash balances, the expected performance of our operations, current metals prices, proceeds from potential at-the-market sales of common stock, and availability under our Credit Agreement, we believe we will be able to meet our obligations and other potential cash requirements during the next 12 months and beyond. Our obligations and other uses of cash may include, but are not limited to: debt service obligations related to the Senior Notes; interest payments under our Credit Agreement; ramp up and suspension costs; capital expenditures at our operations; potential acquisitions of other mining companies or properties; regulatory matters; litigation; potential repurchases of our common stock under the program described above; and payment of dividends on common stock, if declared by our Board of Directors. On August 1, 2025, we issued a notice of redemption for a portion of our Senior Notes and redeemed $212 million of our Senior Notes plus a call premium of $3.8 million. See Note 7 of Notes to Condensed Consolidated Financial Statements (Unaudited)for more information.

While the formerly held Casa Berardi operation was a significant part of our operations, we don't believe its divestiture will have an impact on our ability to meet future obligations due to projected cash flow generation from our remaining operations, as the proceeds were utilized to repay our Senior Notes and eliminate our debt service costs on April 9, 2026. Our obligations and other uses of cash may include, but are not limited to: debt service obligations related to the Senior Notes; interest payments under our Credit Agreement; care and maintenance costs; capital investments at our operations; potential acquisitions of other mining companies or properties; regulatory matters; litigation; potential repurchases of our common stock under the program described above; and payment of dividends on common stock, if declared by our Board of Directors.

2025 may change based upon our financial position, metals prices, and other considerations. Our ability to fund the activities described above will depend on our operating performance, metals prices, our ability to estimate revenues and costs, sources of liquidity available to us, including the revolving credit facility (which requires compliance with certain financial and other covenants), and other factors. A sustained downturn in metals prices, significant increase in operational or capital costs or other uses of cash, poor results of our operating units, our inability to access the credit facility or the sources of liquidity discussed above, or other factors beyond our control could impact our plans.
