THIRD QUARTER HIGHLIGHTS

• Record throughput at Greens Creek; Lucky Friday produced 1 million silver ounces for two consecutive quarters
• Consolidated silver production guidance increased, operating and capital cost guidance maintained
• Deferred approximately $24 million in sales at Greens Creek and Lucky Friday to the fourth quarter
• Keno Hill has completed 30% of total planned pre-production development as of October 31, 2022
• Net loss applicable to common stockholders of $(23.7) million or $(0.04) per share (basic), and adjusted net loss of $(12.0) million or $(0.02) per share¹
• Adjusted EBITDA of $26.6 million, net debt to adjusted EBITDA ratio of 1.9²
• All operations free cash flow positive year to date with total cost of sales for silver of $246.4 million and all-in sustaining cost (AISC) per silver ounce of $10.17
• $144.7 million in cash and cash equivalents with approximately $260 million in available liquidity
• Positive drilling results at Keno Hill and Greens Creek with intercepts in excess of 100 ounces of silver per ton at Keno Hill and wide high-grade intercepts at Greens Creek
• Strong safety performance with an all-injury frequency rate of 1.32 for the first nine months, 37% below the U.S. average and an improvement of 19% over the nine-month period in 2021

"Hecla reported another quarter of solid operational performance as Greens Creek achieved its best ever throughput and Lucky Friday's production exceeded 1 million ounces for the second consecutive quarter," said Phillips S. Baker Jr., President & CEO. "Free cash flow generation was lower for the quarter due to deferral of the sale of about a million ounces of silver and other metals, increased capital investment in our mines, and Alexco acquisition costs. All operations are free cash flow positive year to date and reflect the strong margins at our silver operations despite lower prices and an inflationary environment."

Baker continued, "Hecla is the United States' largest silver miner, producing about 40% of all the silver mined. With Keno Hill's pre-production development on plan, we should become Canada's largest silver miner in the next few years."

FINANCIAL OVERVIEW

"Total cost of sales" as used in this release is comprised of cost of sales and other direct production costs and depreciation, depletion and amortization.

Sales in the third quarter declined by $44.9 million compared to the second quarter of 2022 primarily due to lower realized prices for all metals, and lower revenue from the deferral of silver concentrate shipments from Greens Creek and Lucky Friday to the fourth quarter. Compared to the prior quarter, realized silver prices have declined 12%, gold has declined 8%, lead and zinc prices are lower by 2% and 15% respectively. In comparison to the same quarter last year, gold prices are relatively unchanged, while silver prices have declined by 24% with lead and zinc lower by 7% and 9% respectively. The deferral of approximately 1 million ounces of silver, 1,800 ounces of gold, and 1,300 tons of lead in the silver concentrate shipments at Greens Creek was to ensure adequate volumes of concentrate for cost-effective shipping. At Lucky Friday the deferral was due to a planned multi week shutdown of the Trail smelter for maintenance. This concentrate is being shipped to a new customer and represents approximately 5% of Lucky Friday's annual concentrate production.

Total cost of sales for silver were $76.7 million for the third quarter and were lower by $14.2 million over the prior quarter due to lower depreciation and higher product inventory. Cash costs and AISC (each after by-product credits) for silver were $3.43 and $14.20 per silver ounce respectively. Cash costs increased by $4.57 per ounce over the prior quarter primarily due to lower by-product credits attributable to lower lead and zinc production as well as lower prices. AISC increased by $5.65 per silver ounce over the prior quarter due to the factors affecting cash costs.^4,5

Total cost of sales for gold were $59.5 million and declined marginally over the prior quarter. Gold cash cost per ounce, after by-product credits, declined by $22 attributable to higher production. AISC increased by $97 per ounce due to higher sustaining capital and exploration spend partially offset by higher production.^4,5

Labor and the current inflationary environment are challenging at all operations. Labor availability remains constrained in the market with a shortage of skilled miners and maintenance workers. Inflationary pressures have led to a 10-15% increase in costs since the beginning of the year. Labor and input costs for steel, reagents, fuel, and other consumables continue to remain elevated impacting all the operations.

In the first half of the year, by-product credits helped offset the inflationary pressures for the silver segment due to strong by-product production as well as prices. However, lower base metal production and prices in the third quarter reduced the by-product credits. The inflationary environment is expected to remain challenging for the fourth quarter and into 2023.

Loss applicable to common stockholders for the third quarter was $(23.7) million, or $(0.04) per share, compared to a loss of $(13.7) million, or $(0.03) per share, in the second quarter of 2022, impacted by the following factors:

• Gross profit decreased by $28.8 million primarily due to lower revenues and higher per unit costs as described above
• Exploration and pre-development expenses increased by $3.9 million reflecting increased exploration and drilling activity across Hecla's mines and projects during the exploration season
• General and administrative expenses increased by $1.3 million reflecting incremental costs following the Alexco acquisition

Partially offset by:

• A net foreign exchange gain of $5.7 million versus $4.5 million in the prior quarter reflecting the appreciation of the U.S. dollar ("USD") against the Canadian dollar ("CAD") during the current quarter
• Lower unrealized losses on our investment portfolio of $10.6 million reflecting a smaller reduction in the fair value of the portfolio compared to the prior quarter
• An income tax benefit of $9.5 million versus a provision of $0.3 million in the prior quarter

Cash used in operating activities was $24.3 million, compared to cash provided by operating activities of $40.2 million in the prior quarter. However, cash provided before working capital changes increased over the prior quarter. Working capital changes in the third quarter were negative $36.7 million compared to $32.6 million in the prior quarter, and are primarily related to an increase in ending inventory from the deferral of silver concentrate shipments at Greens Creek and Lucky Friday to the fourth quarter and semi-annual interest payment on the outstanding debt.

Capital expenditures totaled $37.4 million, an increase of $3.1 million over the prior quarter as planned. Expenditures were at Greens Creek of $7.0 million, Lucky Friday of $16.1 million, Casa Berardi of $10.8 million, and Keno Hill of $3.6 million. Free cash flow for the quarter was negative $61.8 million, a decline of $67.6 million over the prior quarter due to the increase in working capital changes and higher capital spend.³

Forward Sales Contracts for Base Metals and Foreign Currency

The Company uses financially settled forward sales contracts to manage exposures to changes in prices of zinc and lead. At September 30, 2022, the Company had contracts covering approximately 39% of the forecasted payable zinc production (through 2025) at an average price of $1.32 per pound, and 38% of the forecasted payable lead production (through 2024) at an average price of $1.00 per pound. The fair value of the net metal derivative contracts on our forecasted hedges was an asset of $27.4 million, an increase of $11.3 million over the prior quarter.

The Company also manages CAD exposure through forward contracts. At September 30, 2022, the Company had hedged approximately 52% of forecasted CAD direct production costs for Casa Berardi through 2026 at an average CAD/USD rate of 1.31. The Company has also hedged approximately 32% of capital costs for Casa Berardi for 2022 at 1.33. At the Keno Hill, 66% of planned spend for the fourth quarter is hedged at an average CAD/USD rate of 1.34. The fair value of the net currency derivatives contracts is a liability of $10.8 million, an increase of $12.7 million over the prior quarter.

Greens Creek produced 2.5 million ounces of silver and the mill achieved record mill throughput of 2,500 tons per day. Lead and zinc production for the quarter declined 15% and 6% respectively due to lower grades which led to the deferral of a silver concentrate shipment into the fourth quarter to ensure adequate volumes for cost effective shipping. Costs associated with the shipment were included in inventory in the third quarter, and the approximate revenue and cash flow impact of this deferral in the fourth quarter is expected to be $18 million.

Cash cost per silver ounce increased by $5.94 over the prior quarter primarily due to lower by-product credits. AISC per silver ounce increased by $5.13 compared to the prior quarter due to the reasons impacting cash costs, and increased exploration which was partially offset by lower capital spending.^4,5

Cash flow from operations for the quarter was $7.7 million, a decline of $34.1 million over the prior quarter; free cash flow for the quarter was $4.5 million, a decline of $23.5 million. For the first nine months of the year, Greens Creek has generated $105.8 million in cash flow from operations and $86.0 million in free cash flow respectively and remains on track to achieve its production and cost guidance for the year.

Lucky Friday produced 1.1 million ounces of silver during the third quarter, a 12% decrease over the prior quarter due to lower mined tons and feed grades attributable to mine sequencing, commissioning of new equipment, and prioritization of projects for increasing future throughput and production. The third quarter also marked two consecutive quarters of throughput exceeding 90,000 tons and silver production exceeding 1 million ounces.

At the Lucky Friday, 2,000 dry metric tonnes of silver concentrate was inventoried to be shipped to a new customer in the fourth quarter. Costs associated with the deferral of this concentrate shipment were in inventory in the third quarter, and impact on revenues and cash flow for the fourth quarter is expected to be approximately $6.0 million. Total cost of sales was $24.2 million, a decrease of $6.2 million over the prior quarter due to lower depreciation expense, an increase in concentrate inventory, and lower ore volume mined and production. Cash cost and AISC per silver ounce (each after by-product credits) were $5.23 and $15.98, respectively, and higher compared to the prior quarter due to lower production, and lower by-product credits because of lower base metal production and prices.^4,5

Casa Berardi produced 33,335 ounces of gold compared to 33,306 ounces in the prior quarter. The mill continues to perform well and operated at an average quarterly throughput of 4,239 tons per day ("tpd") with a new record set in September as monthly production throughput reached 4,856 tpd, beating the last monthly record in May 2022 of 4,533 tpd.

Total cost of sales for the third quarter 2022 was $59.5 million, a reduction of $2.3 million from the $61.9 million in the prior quarter. Cash cost per gold ounce decreased by $22 over the prior quarter to $1,349 primarily due to higher production. AISC per gold ounce increased by $97 to $1,738 driven by higher exploration and capital spend partially offset by higher production.^4,5

Keno Hill - Yukon Territory

At the Keno Hill mine, focus is on development and drilling of the Bermingham and Flame & Moth deposits to bring the mine into full and consistent production by the end of 2023. As of October 31, 2022, 30% of total planned pre-production development is complete, and we expect to complete approximately 50% of the development by the end of the fourth quarter.

Fourth quarter capital spending is forecast at $10-$12 million for development, infill drilling, and equipment purchases. Since the acquisition, Keno Hill is seeing its lowest turnover in the mine's recent history and is expected to achieve the hiring rate for production. We are implementing Hecla's Health and Safety Management System and Environmental Management System in the fourth quarter.

EXPLORATION AND PRE-DEVELOPMENT UPDATE

Exploration and pre-development expenditures were $15.1 million for the quarter with focus on exploration drilling at Keno Hill, exploration and definition drilling at Greens Creek, underground drilling at the West Mine in Casa Berardi, and exploration drilling at the large land packages at Aurora, Nevada and Republic, Washington.

Keno Hill, Yukon Territory

Exploration drilling on the underexplored Coral Wigwam target area has discovered high-grade silver mineralization. Assay results to date include 101.5 oz/ton silver over 7.3 feet estimated true width.

Greens Creek, Alaska

At Greens Creek, drilling has focused on resource expansion and conversion which have yielded positive results. Three underground core drills are focused on resource conversion in the 200 South and East ore zones and on exploration in the East, 5250, 200 South, and Gallagher Fault Block zones. Additionally, two helicopter supported core drills are focused on drilling extensions to the Upper Plate Zone near the mine and the Lil'Sore target area approximately 3 miles northwest of the mine. These positive results continue to confirm and expand mineral zones. Significant assay intercepts for different zones are:

• Southwest Bench: 74.3 oz/ton silver, 0.52 oz/ton gold, 5.7% zinc and 2.9% lead over 10.5 feet and 25.7 oz/ton silver, 0.15 oz/ton gold, 6.4% zinc, and 3.1% lead over 20.1 feet
• 200 South: 18.5 oz/ton silver, 0.02 oz/ton gold, 2.6% zinc, and 1.1% lead over 44.7 feet
• East Zone: 51.6 oz/ton silver, 0.05 oz/ton gold, 0.1% zinc, and 0.0% lead over 11.1 feet and 227.8 oz/ton silver, 2.84 oz/ton gold, 4.2% zinc, and 0.4% lead over 2.9 feet
• West Zone: 37.0 oz/ton silver, 0.26 oz/ton gold, 18.3% zinc, and 9.5% lead over 47.2 feet and 55.2 oz/ton silver, 0.16 oz/ton gold, 16.5% zinc, and 8.9% lead over 31.2 feet

Detailed complete drill assay highlights can be found in Table A at the end of the release.

Casa Berardi, Quebec

At Casa Berardi, up to seven underground core drills and one surface core drill were focused on definition and exploration drilling in multiple zones and target areas and one surface core drill was focused on condemnation drilling.

Drilling targeted the 113, 118, 119 and Lower Inter zones. In the 113 Zone, two drill rigs are testing offsets and depth extensions of multiple 113 lenses. In the 118 Zone, drilling has been focused on defining continuity and expanding mineralization in the 118-14, and 118-15 lenses up and down plunge and to the east. Most of the 118 drilling has been showing good vertical continuity of mineralization. The drilling targeting the 119-02 lens show that the structure remains open at depth while closing to the east. Highlights include:

• 113: 0.56 oz/ton gold over 9.5 feet, including 1.61 oz/ton gold over 2.6 feet
• 118: 0.20 oz/ton gold over 8.2 feet
• 119: 0.16 oz/t gold over 14.8 feet.

More complete drill assay highlights can be found in Table A at the end of the release.

Aurora, Nevada

Exploration drilling has confirmed wide and high-grade vein mineralization along the Martinez-Juniata-Chesco mineral trend. This mineralization continues to be open for expansion along strike and dip. Some significant intercepts are:

• Martinez Zone: 0.40 oz/ton gold and 1.8 oz/t silver over 31.1 feet estimated true width, which includes 1.26 oz/ton gold and 4.4 oz/t silver over 6.7 feet estimated true width.
• Juniata Zone: 0.43 oz/ton gold and 1.9 oz/ton silver over 14.9 feet estimated true width, which includes 0.76 oz/ton gold, 3.5 oz/ton silver over 8.0 feet estimated true width.
• Chesco Zone: 0.73 oz/ton gold and 7.7 oz/ton silver over 12.2 feet estimated true width

Republic, Washington

Exploration drilling identified high-grade vein mineralization at both the Lone Pine-Blacktail and Tom Thumb target areas. Wide zones of lower grade, potentially bulk mineable, material surround some of the high-grade vein intercepts at Lone Pine-Blacktail. Drilling also discovered an offset segment of the Tom Thumb Vein 850 feet across the Mud Lake Fault into the basin.

DIVIDENDS

Common Stock

The Board of Directors declared a quarterly cash dividend of $0.00375 per share of common stock for the minimum dividend component. The common stock dividend is payable on or about December 7, 2022, to stockholders of record on November 25, 2022. The realized silver price was $18.30 per ounce in the third quarter and did not satisfy the criterion for the silver-linked component under the Company's common stock dividend policy.

Preferred Stock

The Board of Directors elected to declare a quarterly cash dividend of $0.875 per share of preferred stock, payable on or about January 3, 2023, to stockholders of record on December 15, 2022.

2022 GUIDANCE

The Company has reaffirmed its guidance for annual production, cost, and exploration and pre-development. The Company is maintaining its consolidated capital guidance with lower forecasted capital spend at the Lucky Friday and Casa Berardi due to timing of expenditures, offset by the inclusion of Keno Hill.

NOTES

Non-GAAP Financial Measures

Non-GAAP financial measures are intended to provide additional information only and do not have any standard meaning prescribed by United States generally accepted accounting principles (GAAP). These measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The non-GAAP financial measures cited in this release and listed below are reconciled to their most comparable GAAP measure at the end of this release.

⁽¹⁾ Adjusted net income (loss) applicable to common stockholders is a non-GAAP measurement, a reconciliation of which to net income (loss) applicable to common stockholders, the most comparable GAAP measure, can be found at the end of the release. Adjusted net income (loss) is a measure used by management to evaluate the Company's operating performance but should not be considered an alternative to net income (loss) as defined by GAAP. They exclude certain impacts which are of a nature which we believe are not reflective of our underlying performance. Management believes that adjusted net income (loss) per common share provides investors with the ability to better evaluate our underlying operating performance.

⁽²⁾ Adjusted EBITDA is a non-GAAP measurement, a reconciliation of which to net income(loss), the most comparable GAAP measure, can be found at the end of the release. Adjusted EBITDA is a measure used by management to evaluate the Company's operating performance but should not be considered an alternative to net income, or cash provided by operating activities as those terms are defined by GAAP, and does not necessarily indicate whether cash flows will be sufficient to fund cash needs. In addition, the Company may use it when formulating performance goals and targets under its incentive program. Net debt to adjusted EBITDA is a non-GAAP measurement, a reconciliation of which to debt and net income (loss), the most comparable GAAP measurements, can be found at the end of the release. It is an important measure for management to measure relative indebtedness and the ability to service the debt relative to its peers. It is calculated as total debt outstanding less total cash on hand divided by adjusted EBITDA.

⁽³⁾ Free cash flow is a non-GAAP measure calculated as cash provided by operating activities less additions to properties, plants and equipment. Free cash flow for Greens Creek, Lucky Friday and Casa Berardi adjusts cash provided by operating activities by excluding exploration and pre-development expense, as it is a discretionary expenditure and not a component of the mines' operating performance.

⁽⁴⁾ Cash cost, after by-product credits, per silver and gold ounce is a non-GAAP measurement, a reconciliation of which to total cost of sales, can be found at the end of the release. It is an important operating statistic that management utilizes to measure each mine's operating performance. It also allows the benchmarking of performance of each mine versus those of our competitors. As a primary silver mining company, management also uses the statistic on an aggregate basis - aggregating the Greens Creek and Lucky Friday mines - to compare performance with that of other silver mining companies, and aggregating Casa Berardi and the Nevada operations, to compare its performance with other gold 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.

⁽⁵⁾ All-in sustaining cost (AISC), after by-product credits, is a non-GAAP measurement, a reconciliation of which to cost of sales and other direct production costs and depreciation, depletion and amortization, the closest GAAP measurement, can be found in the end of the release. AISC, after by-product credits, includes total cost of sales, expenses for reclamation and exploration at the mines sites, corporate exploration related to sustaining operations, 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 cost of goods sold, do not capture all the expenditures incurred to discover, develop and sustain silver and gold production. Management believes that all-in sustaining costs 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.

The tables below present reconciliations between the most comparable GAAP measure of cost of sales and other direct production costs and depreciation, depletion and amortization to the non-GAAP measures of Cash Cost, Before By-product Credits, Cash Cost, After By-product Credits, AISC, Before By-product Credits and AISC, After By-product Credits for our operations at the Greens Creek , Lucky Friday, Casa Berardi and Nevada Operations units for the nine month periods ended September 30, 2022 and 2021 and the three month periods ended September 30, June 30 and March 31, 2022.

Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce are measures developed by precious metals companies (including the Silver Institute and the World Gold Council) in an effort to provide a uniform standard for comparison purposes. There can be no assurance, however, that these non-GAAP measures as we report them are the same as those reported by other mining companies.

Cash Cost, After By-product Credits, per Ounce is an important operating statistic that we utilize to measure each mine's operating performance. AISC, After By-product Credits, per Ounce is an important operating statistic that we utilize as a measures of our mines' net cash flow after costs for exploration, pre-development, reclamation, and sustaining capital. Current GAAP measures used in the mining industry, such as cost of goods sold, do not capture all the expenditures incurred to discover, develop and sustain silver and gold production. Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce also allow us to benchmark the performance of each of our mines versus those of our competitors. As a silver and gold mining company, we also use these statistics on an aggregate basis - aggregating the Greens Creek and Lucky Friday mines - to compare our performance with that of other silver mining companies, and aggregating Casa Berardi and Nevada Operations for comparison to other gold mining companies. Similarly, these statistics are useful in identifying acquisition and investment opportunities as they provide a common tool for measuring the financial performance of other mines with varying geologic, metallurgical and operating characteristics.

Cash Cost, Before By-product Credits and AISC, Before By-product Credits include all direct and indirect operating cash costs related directly to the physical activities of producing metals, including mining, processing and other plant costs, third-party refining expense, on-site general and administrative costs, royalties and mining production taxes. AISC, Before By-product Credits for each mine also includes on-site exploration, reclamation, and sustaining capital costs. AISC, Before By-product Credits for our consolidated silver properties also includes corporate costs for general and administrative expense, reclamation, exploration, and pre-development. By-product credits include revenues earned from all metals other than the primary metal produced at each unit. As depicted in the tables below, by-product credits comprise an essential element of our silver unit cost structure, distinguishing our silver operations due to the polymetallic nature of their orebodies. Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce provide management and investors an indication of operating cash flow, after consideration of the average price, received from production. We also use these measurements for the comparative monitoring of performance of our mining operations period-to-period from a cash flow perspective.

The Casa Berardi, Nevada Operations and combined gold properties information below reports Cash Cost, After By-product Credits, per Gold Ounce and AISC, After By-product Credits, per Gold Ounce for the production of gold, its primary product, and by-product revenues earned from silver, which is a by-product at Casa Berardi and Nevada Operations. Only costs and ounces produced relating to units with the same primary product are combined to represent Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce. Thus, the gold produced at our Casa Berardi and Nevada Operations units is not included as a by-product credit when calculating Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce for the total of Greens Creek and Lucky Friday, our combined silver properties. Similarly, the silver produced at our other two units is not included as a by-product credit when calculating the gold metrics for Casa Berardi and Nevada Operations.
