Third Quarter 2026 Highlights

Current report

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. If the project is approved, intermittent production using temporary equipment could occur from late 2027 through 2028, with construction of the new circuit expected to be completed in late 2028. Thereafter, preliminary metallurgical and engineering work indicate 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.

Current report

We acquired our Keno Hill operation as part of the Alexco Resource Corp. acquisition in September 2022 and since then we have focused on development activities and began ramping up the mill during the second quarter of 2023. The mine is currently permitted to a maximum annual average of 440 tons per day, with average mill throughput during the three months ended September 30, 2026 of 415 tons per day (2025: 323 tons per day), with silver grades milled of 26.2 ounces per ton (2025: 31.8 ounces per ton). In September 2026, the mill averaged 437 tons per day, approximately 99% of the mine's permitted rate. While this demonstrated Keno Hill's value generation at target throughputs, the tailings storage, waste rock disposal, and water treatment capacity available under our current permits will not support that rate until those permits are amended and the related infrastructure is built. As discussed further below under “Strategic Focus and Path to 440 Tons Per Day,” we expect to suppress throughput beginning in the fourth quarter of 2026, with a further reduction beginning in January 2027, and we expect to hold throughput at the lower rate until those permits are amended and the related infrastructure is built.

Current report

We estimate that approximately 200,000 tons of tailings storage capacity remains available under our current permits; additional capacity beyond that, through the next phase of the dry-stack tailings facility (Phase 3), will require permit amendments and related construction. How long the remaining capacity lasts will depend on the rate at which we mill ore and on the tailings generated per ton milled, which varies with ore grades, the characteristics of the ore processed, and the density at which tailings are placed. At milling rates for the nine months ended September 30, 2026, we project that we would exhaust that capacity in the second quarter of 2028, before Phase 3 is expected to be permitted and constructed. In an effort to maintain operational continuity and to extend the remaining capacity until Phase 3 is in place, we plan to suppress throughput as described below under “Strategic Focus and Path to 440 Tons Per Day.” Even at the reduced rate, however, we expect to exhaust our tailings storage capacity unless Phase 3 is permitted and constructed during the 2029 construction season. If it is not, milling could be further curtailed or interrupted. The construction season in the Yukon is approximately April through October, and if permits are received by the first half of 2029, it is possible that tailings expansion could be advanced far enough in 2029 to permit the mill to resume normal production levels, and begin ramping up to higher production levels by the end of 2029.

Current report

We expect to begin suppressing throughput in the fourth quarter of 2026 to approximately 300 tons per day, with further suppression, expected beginning in January 2027 to levels significantly below third quarter 2026 throughput. We expect to provide 2027 production guidance for Keno Hill in February 2027. Available capacity for water treatment, tailings storage, and waste rock disposal under our current permits will not support our current levels of production until our QML and WL are amended and the related projects constructed. We are suppressing throughput to preserve that capacity so that operations can continue until then; this is not a cost-driven decision. We are currently targeting license amendments to be finalized by mid-2029, after which, once the related infrastructure is constructed, we would expect to ramp back up toward throughput of 440 tons per day. Permitting timelines depend on regulatory review outside our control and could be extended. If those permits or the related infrastructure projects are delayed beyond our current schedule, throughput could be constrained further or interrupted entirely until the necessary tailings and waste rock storage capacity is in place.

Current report

We expect silver production to decline by proportionally less than throughput because, during 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 stockpile lower-grade material for later processing. Actual production will depend on the grades, dilution, and recoveries we achieve.

Current report

Our 2027 budgeting process is ongoing and subject to various internal reviews and ultimately Board of Directors approval. Current expectations are that capital investments, exploration and pre-development and general and administrative expenses will exceed 2026 amounts.

Second Quarter 2026 Highlights

Previous report

At Greens Creek, we are evaluating a proposed pyrite concentrate circuit that, if developed, could recover additional silver and gold that currently report to tailings. Preliminary engineering and metallurgical work indicates the potential for incremental future silver and gold production from this circuit, possibly as soon as late 2027 or the first half of 2028. These estimates are preliminary and remain subject to significant technical, economic, permitting, metallurgical, and other uncertainties, and the project has not been approved for construction.

Previous report

Income and mining tax expense decreased by $3.3 million primarily due to the release of a historical valuation allowance related to our Nevada subsidiary, partly offset by the revaluation of the Nevada subsidiary's deferred balance now that they are combined into the Hecla Mining Company Consolidated Group.

Previous report

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 June 30, 2026, was 368 tons per day (2025: 294 tons per day) (the mine is currently permitted to a maximum of an average of 440 tons per day), with silver grades milled of 19.3 ounces per ton (2025: 28.9 ounces per ton). During the first six months of 2026, the mine continued to focus on development and ramp up to higher tonnage rates with mining rates of 332 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 departed that zone and transitioned into the Arctic zone, as well as by mine sequencing at both Bermingham and Flame and Moth deposits, 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. These impacts have diminished, however, near-term production may decrease due to other factors discussed below.

Previous report

The currently permitted dry‑stack tailings storage area at Keno Hill (Phase 2E) is expected to reach capacity in approximately October 2026. We received governmental approvals for the Phase 2W dry‑stack expansion in early July 2026 and have begun construction. We currently expect Phase 2W to become operational before Phase 2E reaches capacity. Further in the future, at current milling rates, we project that we would run out of tailings storage space in the second quarter of 2028. If no alternative storage or disposal solution has been developed by that time, we may reduce mining rates in advance to preserve available storage capacity, which would curtail milling operations, or we may continue mining at or near current rates until storage capacity is reached, which could interrupt milling operations. The construction season in the Yukon is approximately April through October, and if permits are received by the first half of 2029, it is possible that tailings expansion could be advanced far enough in 2029 to permit the mill to resume normal production levels, and begin ramping up to higher production levels by the end of 2029.

Previous report

We continue to study the aforementioned issues to develop a plan to optimize Keno Hill for the periods described herein. Such a plan could result in accelerated production schedules and an earlier transition to care and maintenance. Alternatively, such a plan could result in slower mining rates so that curtailment periods are minimized, or possibly eliminated, until permits are received and sustained, profitable production at higher throughput rates is achievable.

Current wording

We are also evaluating the potential to reprocess all or part of the existing dry-stack tailings facility at Greens Creek. Advances in processing technology and growing market demand for this type of material have created the potential to turn material once managed only as tailings into a marketable low-grade feedstock. This project 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 this low-grade feedstock for shipment and sale to a third-party smelter.

Previous wording

Our financial results vary as a result of fluctuations in market prices primarily for silver and, to a lesser extent, gold, 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 geopolitical uncertainty and global growth expectations, which have resulted in significant volatility in the financial and commodities markets, including the precious metals market. See Item 1A. “Risk Factors” contained in Part I of our 2025 Form 10-K 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 investments, 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, 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 negative price adjustments to provisional settlements of $13.1 million and $6.2 million for the three and six months ended June 30, 2026, respectively, (three and six months ended June 30, 2025: $4.2 million and $11.1 million positive adjustments, 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, and zinc. Realized prices are calculated by dividing gross revenues for each metal (which include the price adjustments and gains and losses on the metals derivative contracts discussed below) by the payable quantities of each metal included in concentrate, doré, and carbon material shipped during the period.

Previous wording

we have historically presented Greens Creek and Lucky Friday as primary silver producers, based on the original analysis that justified putting the project into production, and the same analysis applies to Keno Hill. Further we believe that consistency in disclosure is important to our investors regardless of the relationships of metals prices and production from year to year;

Previous wording

We periodically review our revenues to ensure that reporting of primary products and by-products is appropriate. Because we consider zinc, lead, gold, and copper at Greens Creek, Lucky Friday, and Keno Hill to be by-products of our silver production, the values of these metals offset operating costs within our calculations of Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce. We currently do not report Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce for our Keno Hill operation as it has not met our definition of commercial production. We define an operation as being in commercial production upon achievement of the following criteria:

We define an operation as being in commercial production upon achievement of all of the following criteria:

Previous wording

Currently we meet only one of the above criteria - silver recoveries are at expected steady-state production levels. Determination of when these criteria have been met requires the use of judgment, and our definition of commercial production may differ from that of other mining companies.

Current wording

Determination of when these criteria have been met requires the use of judgment, and our definition of commercial production may differ from that of other mining companies. Currently Keno Hill meets two of the above criteria - silver recoveries are at expected steady-state production levels, and a significant portion of available funding allocated to Keno Hill is directed to operating activities.

Previous wording

As Keno Hill has not yet been determined to be in commercial production, its costs and by-product credits are excluded from our consolidated Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce because (i) by definition it has not reached the sustaining stage and (ii) including its costs and by-product credits we believe would distort consolidated Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce of our operating silver mines that are in commercial production and operating as designed, and would not facilitate a meaningful comparison of our performance versus that of our peers who do not report such metrics for mines that are not in commercial production.

Current report — wording carried from elsewhere

Our current QML places limits on the cumulative amount of waste rock that may be produced during mining and on waste rock storage capacity and classification. At current mining rates, we project that the waste rock production limit could be reached by approximately mid‑2027, at which point waste rock production would need to be halted absent receipt of a QML amendment. The planned suppression in throughput described below under “Strategic Focus and Path to 440 Tons Per Day” is intended to keep waste rock production and storage within our existing QML limits until the amended QML is received, which we currently expect by approximately mid‑2029.
