HECLA REPORTS SECOND QUARTER 2022 RESULTS

9th consecutive quarter of free cash flow generation, consolidated silver guidance affirmed

Hecla Mining Company (NYSE:HL) today announced second quarter 2022 financial and operating results.

SECOND QUARTER HIGHLIGHTS

• Silver and gold production of 3.6 million and 45,719 ounces respectively, a 10% increase over the first quarter 2022 ("the prior quarter")
• Sales of $191.2 million, a 3% increase over the prior quarter despite lower gold and silver prices
• Cash provided by operating activities of $40.2 million and $5.9 million in free cash flow with continued positive free cash flow generation from all three operations³
• Total cost of sales for silver of $90.9 million and cash cost and all-in sustaining cash cost (AISC) per ounce (each after by-product credits) of ($1.14) and $8.55 respectively^1,2
• Net loss applicable to common shareholders of $13.7 million or $0.03 per share (basic), and adjusted net income of $20.1 million or $0.04 per share⁵
• Adjusted EBITDA of $70.5 million, net debt/adjusted EBITDA (last 12 months) of 1.4x ⁴
• $198.2 million in cash and cash equivalents with approximately $335 million in available liquidity
• Pending acquisition of Alexco Resource Corp ("Alexco") and its high-grade silver property in Yukon; transaction expected to close in early September
• Published 2021 Sustainability report 'Building Strong Communities Through Responsible Mining'

“All three of our mines continue to deliver strong operational and financial results with each generating positive free cash flow," said Phillips S. Baker Jr., President & CEO. “Lucky Friday achieved record quarterly tons milled reflecting the significant strides we have made in managing seismicity and improving productivity with the Underhand Closed Bench (UCB) mining method. I strongly believe as we optimize this mining method, the Lucky Friday along with Greens Creek will further increase our position as the dominant U.S. silver producer."

Baker continued, "While we are exposed to inflationary pressures like the rest of the industry, our silver mines have largely been able to offset inflation with by-product credits. For the second half of the year with our strong balance sheet, we plan to increase our investment in operations with the goal of further accelerating production, earnings and cash flow growth. We are looking forward to closing the Alexco acquisition, which adds a high-grade silver property in the Yukon to our best in class portfolio. This acquisition could make Hecla the largest silver producer in Canada, as well as the United States, an important and a unique characteristic of Hecla among all silver producers for decades to come."

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.

Loss applicable to common shareholders for the second quarter was $13.7 million, or $(0.03) per share, compared to income of $4.0 million, or $0.01 per share, in the first quarter of 2022, and was impacted by the following factors:

• Gross profit decreased by $8.2 million primarily due to lower realized prices for all metals and higher mining costs at Greens Creek caused by increased use of contractors
• A negative fair value adjustment, net of $16.4 million, versus a gain of $6.0 million in the prior quarter, primarily due to unrealized losses on the Company's investment portfolio of $15.7 million during the second quarter

These decreases were partially offset by:

• Higher sales volume at Greens Creek and Lucky Friday
• Lower income and mining tax provision of $0.3 million compared to $5.6 million in the prior quarter reflecting lower income from operations
• A net foreign exchange gain of $4.5 million versus a loss of $2.0 million in the prior quarter reflecting the appreciation of the U.S. dollar (“USD”) against the Canadian dollar (“CAD”) during the current quarter
• Lower exploration and pre-development expense of $1.6 million versus the prior quarter reflecting timing of expenditures across the Company's exploration portfolio

Cash provided by operating activities of $40.2 million increased $2.3 million compared to the prior quarter, primarily due to positive working capital changes of $32.6 million reflecting the semi-annual interest payment on the outstanding long-term debt in the prior quarter.

Capital expenditures totaled $34.3 million, an increase of $12.9 million over the prior quarter with increased planned expenditures at Greens Creek of $14.7 million, Lucky Friday of $11.5 million, and Casa Berardi of $8.1 million. Free cash flow for the quarter was $5.9 million, a decrease of $10.6 million over the prior quarter primarily due to higher capital expenditures.

Cash costs and AISC (each after by-product credits) for silver were $(1.14) and $8.55 per ounce respectively. Cash costs declined by $2.23 per ounce over the prior quarter due to higher by-product credits at Greens Creek and higher silver production at the Lucky Friday as well as Greens Creek. AISC increased by $0.91 over the prior quarter, as a result of increased sustaining capital spend at both Greens Creek and Lucky Friday, partially offset by increased production at the Lucky Friday.

Gold cash cost per ounce and AISC declined by $145 and $169, respectively, attributable to higher gold production during the second quarter.

The Company is seeing the impact of inflationary pressures and labor constraints at all its operations. By-product credits continue to help offset the inflationary pressures for the silver segment due to strong by-product production and prices. At the Casa Berardi mine, while AISC per gold ounce after by-product credits declined over the prior quarter, the mine continues to see 15-20% overall increases in costs, notably impacting fuel, steel, reagents, and other consumables that have a greater impact on this mine because it handles the largest volume of ore and waste among the three operations. While Casa Berardi is focused on increasing underground ore feed to the mill, the mill is kept full with ore sourced from the surface, which exposes the mine to further inflationary pressures due to relatively higher volume of material moved.

Inflation is also impacting capital projects, particularly at the Lucky Friday where multiple projects are underway to support the production growth.

At the time of guidance issuance earlier this year, inflation expectations were 5%, which have been surpassed in the first half of the year. The Company expects these inflationary pressures to continue in the second half of the year at similar levels seen in the first half of the year and has revised gold cost guidance for Casa Berardi. The Company has also revised the consolidated capital expenditure guidance to reflect sustained inflationary pressures and to account for supply chain uncertainties that might delay equipment delivery schedules to 2023.

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 June 30, 2022, the Company had contracts covering approximately 65% of the forecasted payable zinc production (through 2025) at an average price of $1.32 per pound, and 49% of the forecasted payable lead production (through 2024) at an average price of $0.99 per pound.

The Company manages CAD exposure through forward contracts. At June 30, 2022, the Company had hedged approximately 43% of forecasted CAD direct production costs through 2025 at an average CAD/USD rate of 1.30. The Company has also hedged approximately 32% of capital costs for 2022 at 1.29.

OPERATIONS OVERVIEW

Greens Creek Mine - Alaska

Total cost of sales for the second quarter 2022 was $60.5 million compared to $49.6 million in the prior quarter. Cash cost and AISC per silver ounce (each after by-product credits) were $(3.29) and $3.48, respectively. Cash cost per silver ounce decreased by $2.39 over the prior quarter due to higher by-product credits and additional silver production which was due to increasing mined grades which more than offset higher costs primarily driven by the use of contractors. AISC per silver ounce increased by $1.58 compared to the prior quarter due to planned increased capital spending for the capital projects and additional definition and development drilling.^1,2 The decline in cash flow from operations is primarily due to lower metals prices and increased costs due to inflation

Lucky Friday Mine – Idaho

Lucky Friday produced 1.2 million ounces of silver during the second quarter, a 38% increase over the prior quarter due to higher production resulting from higher throughput due to the UCB mining method and a 9% increase in grade. The throughput rate and the mined tons in the quarter are the highest in the mine's 80-year history. The UCB method mined 91% of tons in the second quarter compared to 82% of tons in the second quarter of 2021.

Total cost of sales for the second quarter 2022 was $30.3 million, an increase of $1.1 million over the prior quarter due to increased use of consumables to support higher mining volumes and higher contractor costs resulting from manpower shortages. Cash cost and AISC per silver ounce (each after by-product credits) were $3.07 and $9.91, respectively, and decreased over the prior quarter due to higher production, the reasons outlined above, and higher by-product credits^1,2

Casa Berardi Mine - Quebec

Casa Berardi produced 33,306 ounces of gold compared to 30,240 ounces in the prior quarter, an increase of 10% due to higher grades milled as more material was sourced from the underground mine. The mill continued to perform well, operating at an average of 4,413 tons per day ("tpd") in the second quarter of 2022 compared to 4,291 tpd over prior quarter.

Total cost of sales for the second quarter 2022 was $61.9 million compared to $62.2 million in the prior quarter. Cash cost and AISC per gold ounce decreased by $145 per ounce and $169 per ounce over the prior quarter to $1,371 and $1,641, respectively, with the decrease primarily driven by higher production. ^1,2

EXPLORATION AND PRE-DEVELOPMENT UPDATE

Exploration and Pre-development expenditures were $11.2 million for the quarter with the focus on both surface and underground drilling at Greens Creek, underground drilling at Casa Berardi and the re-initiation of exploration at the large land packages at Republic, Washington; Creede, Colorado and Aurora, Nevada. Programs continued at San Sebastian and Midas with permitting for water removal at Hollister advancing.

Greens Creek

At Greens Creek, three underground core drills focused on resource conversion in the Southwest Bench, 200 South, East, and West ore zones and exploration in the East and Gallagher Fault Block zones while two helicopter supported core drills started drilling extensions to the Upper Plate Zone from surface late in the Quarter. Assay results received during the 2^nd quarter for drilling in the Southwest Bench, 200 South, East, West, and 9A areas are confirming and expanding all mineral zones.

Southwest Bench drilling during the quarter targeted inferred resource areas along a strike length of 400 feet with the goal of upgrading and expanding resources. Highlights from this drilling includes 42.7 oz/ton silver, 0.09 oz/ton gold, 18.8% zinc and 8.9% lead over 7.4 feet.

200 South drilling targeted the southern portion of the zone along a strike length of 600 feet and along with assay results received during the quarter, the 200 South drilling confirms the expansion of the deep bench up and down dip 50 feet, and down plunge 100 feet, from previous ore grade intercepts. Intercepts characteristic of this portion of the 200 South zone include 83.2 oz/ton Ag, 0.12 oz/ton Au, 3.1 % Zn, and 1.7% Pb over 7.2 feet. Assays received also confirm the expansion of the middle bench 100 feet down plunge from previous ore grade intercepts and includes 15.8 oz/ton Ag, 0.03 oz/ton Au, 1.5% Zn, and 0.6% Pb over 21.3 feet.

Drilling in the central portion of the East Zone focused on infilling areas between existing ore intercepts along the mine contact over a strike length of 850 feet. While limited assay results have been received so far, intercepts are typically narrow and can contain high-grade mineralization such as hole GC5716 with 429.0 oz/ton silver, 1.38 oz/ton gold, 6.4% zinc, and 1.7% lead over 1.0 foot.

Drilling at the West Zone targeted 400 feet of mine contact strike to upgrade and expand known mineralization. Assay highlights from this drilling include intercepts containing 50.4 oz/ton silver, 0.30 oz/ton gold, 14.4% zinc, and 7.6% lead over 57.1 feet. Assays results were received from 9A Zone drilling completed during the first quarter. Highlights from this drilling include 55.3 oz/ton silver, 1.3 oz/ton gold, 16.9% zinc, and 9.1% lead over 14.3 feet.

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

Casa Berardi

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 targets in the West Mine, Principal Mine, and East Mine areas. In addition to drilling in the mining lease, one surface Sonic drill completed the initial drill testing of three small, select historical gold till anomalies in the West, Central, and East Blocks of our large Casa Berardi property package which covers 23 miles of strike length along the Casa Berardi Break.

Drilling in the West Mine targeted the 118 zone where drilling has been focused on defining continuity and expanding mineralization in the 118-06,14, and 15 lenses up and down plunge and to the east. Highlights from this drilling includes an intercept grading 0.45 oz/ton gold over 14.1 feet which is located down plunge from the 118-06 lens showing that mineralization extends at least 360 feet below the current model and follow up exploration drilling is being planned to further test this zone at depth.

Drilling in the Principal Mine targeted the 119, Lower 123, and extensions of the 124 and 134 zones. In the 119 Zone, drilling is focused on defining the controls of mineralization in the 119-02 lens with recent intercepts including 0.14 oz/ton gold over 6.2 feet. Drilling at depth and to the west of the Lower 123 Zone intersected 0.17 oz/ton gold over 21.0 feet expanding mineralization 100 feet to the east of the modeled 123-02 lens. Surface drilling targeting the area between the 124 and 134 zones focused on expanding and connecting mineralization between these two zones which could have a positive impact on future mining in the proposed Principal and 134 open pits. Highlights from this drilling include 0.10 oz/ton gold over 48.9 feet and 0.07 oz/ton gold over 71.1 feet.

Exploration drilling in the East Mine targeted expanding mineralization in the 148 zone. Assay results have been received for one drillhole which extends high-grade mineralization an additional 85 feet to the east of the 148-01 lens. This drillhole grades 0.27 oz/ton gold over 24.6 feet and includes a narrower and higher-grade section grading 2.81 oz/ton gold over 1.6 feet. This drillhole intercept opens the area at depth and to the east for expansion.

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

San Sebastian

Exploration at San Sebastian advanced drill testing multiple targets within the district in addition to completing our Short Vertical Reverse Circulation (SVRC) drilling in areas under cover between the San Sebastian Mine and La Roca target areas.

Republic

Surface exploration is underway at our Republic District, which has had very limited exploration since we ceased underground mining operations in 1994. So far this year, we have completed a geophysical survey, detailed surface mapping and sampling, and one core drill is on site testing the Lone Pine-Blacktail and Tom Thumb target areas.

Drilling to date has been focused on the Blacktail target and four drillholes have been completed. The Blacktail target area is currently being evaluated for both bulk-tonnage mineralization as well as narrow underground mineable mineralization. Several known vein zones including the Belligerent, Bellicose, and Apex veins have been intersected in the current drilling in addition to multiple zones of small veins and veinlets. Assay results have been received for the high priority vein zones in the first three core holes and highlights from this initial drilling include 0.57 oz/ton gold and 5.7 oz/ton silver over 8.1 feet in the Belligerent Vein and 0.40 oz/ton gold and 0.3 oz/ton silver over 5.1 feet in an unnamed vein.

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

San Juan

Surface exploration is also underway at our Creede District in Colorado. Detailed surface mapping is underway in the areas north and west of the Bulldog vein system detailing the Alpha Corsair, Pathfinder, and Rat Creek Basin target areas known to have large alteration footprints at the surface and very limited exploration. We also have one core drill testing the North Bulldog target area. This drilling is focused on following up on a narrow high-grade silver intercept that was intersected high in the volcanic stratigraphy in a poorly welded tuff. Current drilling is targeting the northern extension of the Bulldog structure deeper within the Campbell Mountain welded tuff which is historically the best host to mineralization in the district.

In addition to exploration drilling, Phase 1 of the Bulldog underground rehabilitation work is in progress which is designed to provide long-term access and water management and provide access for underground exploration and resource confirmation drilling.

Nevada

Drilling with two drill rigs at Midas continued to focus on drill testing the Racer structure within the East Graben Corridor along 1.7 miles of strike length and drill testing several other targets in the district including Little Opal, Southern Cross, Silica Ridge, SVI, and Vapor Trail.

Drilling at Aurora began during the quarter with one core drill targeting areas within the Martinez and Last Chance Hill target areas. The initial drillholes are testing, confirming, and defining the character of mineralization contained in some of the historical high-grade reverse circulation drillhole intercepts.

ALEXCO ACQUISITION UPDATE

On July 5, 2022, the Company announced a definitive agreement to acquire all outstanding common shares of Alexco that Hecla does not already own. Each outstanding common share of Alexco will be exchanged for 0.116 of a share of Hecla common stock implying consideration of US$0.47 per Alexco common share based on the companies’ 5-day volume weighted average price on the NYSE and NYSE American on July 1, 2022. As part of the agreement, Hecla agreed to (i) provide interim financing of $30 million to provide working capital and ensure the development and exploration at Keno Hill continues to be advanced and (ii) subscribe for additional common shares bringing its ownership stake to 9.9%. At the time of this release, of the $30 million interim financing, $20 million has been drawn and the subscription of common shares has been completed. The Company has also entered into an agreement with Wheaton Precious Metals Corporation to terminate its silver streaming interest at Alexco’s Keno Hill property in exchange for US$135 million of Hecla common stock conditional upon the completion of Hecla’s acquisition of Alexco. On July 27, 2022 the Supreme Court of British Columbia issued an interim order authorizing the holding of Alexco's special meeting of its security holders to consider and, if deemed advisable, to pass a special resolution implementing Hecla's acquisition of Alexco. The acquisition is expected to close in early September 2022.

Upon closing of the acquisition, the Company expects to focus on (i) development and drilling at the Bermingham and Flame & Moth deposits over the next 12-18 months to open multiple sources of feed, (ii) to complete certain underground infrastructure projects, and (iii) to make improvements to the processing facility. At the Bermingham deposit, development will focus on the Bear zone to open working faces in addition to infill definition drilling. At the Flame & Moth deposit, the Company anticipates advancing development and conducting infill drilling focusing on the upper Lightning zone.

CREDIT FACILITY

On July 21, 2022, the Company entered into a new senior secured revolving credit facility of $150 million with a $75 million accordion feature. The facility has a maturity date of July 21, 2026 and will incur an interest rate at SOFR plus margins ranging from 0.10% to 0.25% plus an applicable margin between 2.00% and 3.50% depending on our total leverage ratio. The facility is collateralized by a mortgage on the Greens Creek mine and the equity interests of subsidiaries that own the Greens Creek mine or are part of the Greens Creek Joint Venture. Proceeds of the revolving loans under the facility may be used for general corporate purposes. Bank of America acted as the Administrative Agent and Sole Lead Arranger and Sole Bookrunner.

In connection with entry into the New Credit Agreement, the Company’s prior Fifth Amended and Restated Credit Agreement dated as of July 16, 2018, was terminated on July 21, 2022.

DIVIDENDS

Common Stock

The Board of Directors declared a quarterly cash dividend of $0.00625 per share of common stock, consisting of $0.00375 per share for the minimum dividend component and $0.0025 per share for the silver-linked component. The common stock dividend is payable on or about September 2, 2022, to stockholders of record on August 19, 2022. The realized silver price was $20.68 per ounce in the second quarter satisfying 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 October 1, 2022, to stockholders of record on September 15, 2022.

2022 GUIDANCE⁶

The Company has updated its guidance for annual cost and capital guidance as below. There is no change to the production guidance. The Company is also providing guidance for capital expenditures planned by the three operations.

2022 Cost Outlook

Annual guidance for Greens Creek's cost of sales has increased to reflect certain inflationary pressures. Increased production and by-product prices in the first half of the year are expected to more than offset inflation and as a result, Greens Creek's 2022 guidance for cash cost and AISC has been reduced. At the Lucky Friday, increased costs of sales guidance is driven by additional throughput as well as higher labor and other key input costs, which have resulted in increased 2022 guidance for cash cost and AISC. At the Casa Berardi mine, increased cost of sales guidance reflects higher costs of energy, materials and labor and continued usage of contractors to supplement manpower due to labor shortages in the area. Costs in the second half are expected to remain similar to levels seen in the first half of the year resulting in increased guidance for 2022 cash costs and AISC.

2022 Capital and Exploration Outlook

Consolidated capital guidance is increased for the year to include further inflationary pressures, expansion in scope and acceleration of certain capital projects from 2023 to 2022. At the Greens Creek mine, planned capital spend is expected to increase marginally as some planned expenditures from 2023 will be accelerated to the second half of 2022. At the Lucky Friday, capital expenditures for the second half are expected to increase approximately two fold compared to the first half of 2022 primarily due to expansion in scope, advancement of expenditures from 2023 into 2022, and inflationary adjustments. Capital expenditures at the Casa Berardi over the next six months are forecast to increase primarily due to design change in the planned raise of tailings storage cell #7.

Guidance for exploration and pre-development expenditures is unchanged.

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⁾ 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.

⁽²⁾ 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.

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

⁽⁴⁾ 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.

⁽⁵⁾ 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.

Other

⁽⁶⁾ Expectations for 2022 include silver, gold, lead and zinc production from Greens Creek, Lucky Friday and Casa Berardi converted using Au $1,700/oz, Ag $22/oz, Zn $1.50/lb., and Pb $1.00/lb. Numbers may be rounded.

In addition, material risks that could cause actual results to differ from forward-looking statements include, but are not limited to: (i) gold, silver and other metals price volatility; (ii) operating risks; (iii) currency fluctuations; (iv) increased production costs and variances in ore grade or recovery rates from those assumed in mining plans; (v) community relations; (vi) conflict resolution and outcome of projects or oppositions; (vii) litigation, political, regulatory, labor and environmental risks; (viii) exploration risks and results, including that mineral resources are not mineral reserves, they do not have demonstrated economic viability and there is no certainty that they can be upgraded to mineral reserves through continued exploration; (ix) the failure of counterparties to perform their obligations under hedging instruments; (x) we take a material impairment charge on our Nevada operations; (xi) we are unable to remain in compliance with all terms of the credit agreement in order to maintain continued access to the revolver, and (xii) we are unable to refinance the maturing senior notes. For a more detailed discussion of such risks and other factors, see the Company’s 2021 Form 10-K, filed on February 23, 2022, with the Securities and Exchange Commission (SEC), as well as the Company’s other SEC filings, including its Quarterly Report on Form 10-Q filed with the SEC on or about August 4, 2022.
