Consolidated cash flow from operations of $23.8 million for the quarter, and year to date $64.4 million; with silver operations generating $62.2 million in cash flow from operations for the quarter and year to date $151.7 million.
Silver operations generated $38.8 million in free cash flow for the quarter, and year to date $107.4 million.²Since 2020, silver operations have generated cash flow from operations of $788 million and free cash flow of $566 million.
Net loss applicable to common stockholders of $(15.8) million or $(0.03) per share and adjusted net income of $15.1 million or $0.03 per share.⁵
Strong balance sheet with $106.8 million in cash and cash equivalents, and available liquidity of $219 million.

Environmental, Social, Governance

Strong safety performance with an all-injury frequency rate of 1.18, the lowest in Company history.

Strategic

Acquired ATAC Resources on July 7^th for $18.8 million in Hecla stock, adding a massive land package of over 700 square miles comprised of the Rackla and Connaught properties in the Yukon.

"Our silver operations reported another solid quarter of operational and financial performance with strong free cash flow generation and our lowest all-injury frequency rate in our history," said Phillips S. Baker Jr., President and CEO. "Greens Creek continued its strong and consistent performance, Lucky Friday produced the most silver in a quarter since 2000, and with the service hoist now operational, this mine is closer to achieving 425,000 ore tons in annual throughput by year-end, and we restarted the Keno Hill mill during the quarter."

Baker continued, "Our silver mines have generated $107 million in free cash flow in the first half of the year and in excess of $560 million since 2020. With this free cash flow, we are investing to extend the mine lives and increase the production of our mines making Hecla the fastest growing established silver producer with 17 million ounces of production expected this year and about 20 million ounces by 2025, all in the U.S. and Canada."

Baker concluded, “Silver is an essential metal in powering the transition to a green economy, particularly photovoltaics, whose rapid growth is now using 15 to 20% of global annual silver production. Hecla, with our growing, long-lived, low-cost mines, is well positioned to reliably provide the silver the world needs."

Sales in the second quarter declined by 11% to $178.1 million from the first quarter of 2023 ("prior quarter") due to lower quantities of all metals sold and lower realized lead and zinc prices, partially offset by higher precious metals prices.

Gross profit increased to $37.7 million, an increase of 8% over the prior quarter, as lower total cost of sales attributable to lower quantities of metals sold offset lower sales.

Net loss applicable to common stockholders was $(15.8) million in the second quarter due to:

Increased ramp-up and suspension costs of $5.0 million, reflecting the impact of the suspension of operations at Casa Berardi in June due to wildfires in Quebec and the start-up of Keno Hill.
Increased provision for closed operations and environmental matters of $2.1 million reflecting adjustments to the reclamation costs at the legacy Johnny M and Durita properties.
An unrealized loss on investments of $5.6 million compared to a gain of $2.2 million, reflecting changes in the fair value of our marketable securities portfolio.
A foreign exchange loss of $3.9 million compared to a gain of $0.1 million, reflecting the impact of the appreciation of the Canadian dollar on our monetary assets and liabilities.
Increased income and mining tax expense of $1.9 million, reflecting increased taxable income from our U.S. assets.

The above items were partly offset by:

Lower adjustments of inventory to net realizable value of $1.5 million at our Casa Berardi and Nevada operations.
Lower depreciation, depletion, and amortization expense of $6.3 million, reflecting the impact of the suspension of operations in June at Casa Berardi and lower silver sales.

Consolidated silver’s total cost of sales in the second quarter decreased by 4% to $96.8 million from the prior quarter, primarily due to lower concentrate tons sold, partially offset by higher production costs at Lucky Friday. Cash costs and AISC per silver ounce, each after by-product credits, were $3.32 and $11.63, respectively.^3,4The increase in cash costs per ounce was due to higher production costs at Lucky Friday, lower consolidated silver production, and lower base metal by-product credits attributable to lower realized prices partially offset by higher Greens Creek gold production and realized price. AISC was further impacted by higher planned sustaining capital spending at the silver operations.^3,4

Consolidated total gold cost of sales decreased by 32% to $43.6 million in the second quarter due to lower production costs attributable to the June wildfires-related suspension at Casa Berardi. Cash costs and AISC per gold ounce, each after by-product credits, were $1,658 and $2,147, respectively.^3,4The decrease in cash costs per ounce was attributable to lower production costs partially offset by lower gold production at Casa Berardi, with AISC also impacted by lower sustaining capital spend.

Adjusted EBITDA for the second quarter increased by 9% to $67.7 million compared to the prior quarter due to higher gross profit, lower general and administrative expenses, and monetization of zinc hedges. During the quarter, average zinc prices declined to $1.15/lb., the lowest since April 2020 and a 19% decrease over the prior quarter. The Company monetized its zinc hedge contracts for proceeds of $7.6 million during the quarter.

The ratio of net debt to Adjusted EBITDA increased to 2.1 for the second quarter due primarily to the wildfires-related suspension at the Casa Berardi mine. With Keno Hill's ongoing ramp-up to full production, and Casa Berardi resuming production, the Company expects net debt to Adjusted EBITDA ratio to decline to less than the Company's target of 2.¹

Cash and cash equivalents at the end of the second quarter were $106.8 million and included $31 million drawn on the revolving credit facility. Available liquidity was $219 million as of the end of the quarter.

Cash provided by operating activities was $23.8 million and decreased by $16.8 million over the prior quarter primarily due to unfavorable working capital changes partially attributable to the increase in product inventory at the Lucky Friday and Keno Hill as it commenced production during the quarter, and payment of 2022 incentive compensation.

Capital expenditures were $51.5 million (net of finance leases of $15.2 million) in the second quarter, compared to $54.4 million in the prior quarter (net of finance leases of $0.9 million). Capital spend at Casa Berardi was for purchases of open pit equipment for approximately $11.9 million (partially financed by leases of $6.6 million) as the mine begins the transition from underground and open pit production to all production from surface operations. The increase in Greens Creek's capital spend was related to the timing of equipment purchases and seasonal surface projects, with the increase in Lucky Friday's capital spend also impacted by the timing of equipment purchases and the service hoist and coarse ore bunker projects. Keno Hill's capital spend was $3.5 million (net of finance leases of $6.7 million) and declined over the prior quarter as the mine began ramp-up to full production during the quarter.

Free cash flow for the quarter was negative $27.7 million, compared to negative $13.8 million in the prior quarter. The decrease in free cash flow was attributable to lower cash flow from operations attributable to unfavorable working capital changes during the quarter.²

Forward Sales Contracts for Base Metals and Foreign Currency

The Company uses financially settled forward sales contracts to manage exposures to zinc and lead price changes in forecasted concentrate shipments. On June 30, 2023, the Company had contracts covering approximately 39% of the forecasted payable lead production from 2023 - 2025 at an average price of $0.99 per pound.

The Company also manages CAD exposure through forward contracts. At June 30, 2023, the Company had hedged approximately 48% of forecasted Casa Berardi CAD direct production costs through 2026 at an average CAD/USD rate of 1.32. The Company has also hedged approximately 22% of Casa Berardi capital costs through 2026 at 1.35. At Keno Hill, 54% of the total planned spend for 2023 and 2024 is hedged at an average CAD/USD rate of 1.36.

Greens Creek produced 2.4 million ounces of silver in the second quarter, a decrease of 15% over the prior quarter due to expected lower mined grades. Gold production increased by 10% to 16,351 ounces due to higher grades; zinc and lead production was consistent with the prior quarter. Throughput for the quarter was 2,555 tons per day ("tpd"), and the mine remains on track to achieve an annual throughput of 2,600 tpd by year-end.

Sales in the second quarter were $95.9 million, a decrease of 3% over the prior quarter due to lower realized prices for base metals, primarily zinc, and lower payable metals sold (except gold), partially offset by higher realized prices for silver and gold. Total cost of sales were $63.1 million, and decreased by 5% over the prior quarter due to lower sales volumes, and lower production costs attributable to lower fuel prices. Cash costs and AISC per silver ounce, each after by-product credits, were $1.33 and $5.34 and increased over the prior quarter as lower production costs were offset by lower base metal by-product credits (primarily zinc, due to lower prices) and lower silver production. Increased AISC per silver ounce was attributable to higher sustaining capital spend of $8.8 million due to timing of equipment purchases and surface projects.^3,4

Cash flow from operations was $43.3 million, in line with the prior quarter. Capital spend was $8.8 million (all sustaining) during the quarter, an increase of $2.2 million over the prior quarter due to the timing of equipment purchases and seasonal construction projects. Free cash flow for the quarter was $36.2 million, a slight decrease over the prior quarter due to higher exploration and capital spend. The Greens Creek mine generated $73.4 million in free cash flow during the first half of 2023.²

Lucky Friday produced 1.3 million ounces of silver, an increase of 2% over the prior quarter due to higher grades partially offset by lower throughput due to the local utility's unplanned replacement of the main electrical transformer. Second quarter silver production was the highest since the first quarter of 2000, marking the fifth consecutive quarter of silver production exceeding one million ounces. Throughput for the quarter was 1,033 tpd and is expected to increase to an annual rate of 425,000 tons by year end.

Sales in the second quarter were $42.6 million, a decrease of 13% over the prior quarter, attributable to a combination of lower payable metals sold and lower realized base metals prices, partially offset by higher realized silver prices. Lower payable metals sold was due to an increase in silver concentrate inventory (impact of approximately $3 million) as maintenance activities impacted a smelter’s ability to take delivery of certain shipments at quarter end, with the sales deferred to the third quarter. Total cost of sales were $32.2 million, a decrease of 7% over the prior quarter primarily due to lower concentrate volumes sold. Production costs at the mine increased over the prior quarter due to higher labor costs related to the new Collective Bargaining Agreement ("CBA") signed in the first quarter of 2023 (CBA related costs are expected to be $2.5 million for the year), and higher consumables costs partially offset by lower fuel costs. Cash costs and AISC per silver ounce, each after by-product credits, were $6.96 and $14.24 respectively, with the increase primarily attributable to higher production costs, lower zinc by-product credits due to lower realized prices, partially offset by higher silver production.^3,4 AISC per silver ounce was further unfavorably impacted by higher sustaining capital spend reflecting accelerated project completion.^3,4

Cash flow from operations was $18.9 million, a decrease of $27.2 million over the prior quarter. The decrease was attributable to lower sales, higher production costs, unfavorable working capital changes and the prior quarter's favorable impact of $6.7 million receipt related to payment for a silver concentrate shipment shipped in the fourth quarter of 2022. Capital expenditures for the quarter totaled $16.3 million (net of $2.0 million in finance leases), comprised of approximately $9.2 million each in sustaining and growth capital, which included the coarse ore bunker and the service hoist projects. The service hoist project was completed in early August, and the coarse ore bunker project which will decouple the mill from the mine, is expected to be completed in the fourth quarter. Free cash flow was $2.6 million, a decrease of $28.8 million over the prior quarter primarily due to the decrease in cash flow from operations and higher capital spend during the quarter.²Lucky Friday generated $34.0 million in free cash flow during the first half of 2023.²

Casa Berardi produced 18,901 ounces of gold in the second quarter, a decrease of 23% over the prior quarter, primarily due to lower tons mined and milled because of wildfires-related suspension in June. The mill operated at an average of 4,600 tpd during the first two months of the quarter.

Lower production during the quarter led to lower sales of $36.9 million, a 28% decrease over the prior quarter, and lower total cost of sales of $42.6 million, 32% lower compared to the prior quarter. Cash costs and AISC per gold ounce, each after by-product credits, were $1,658 and $2,147 respectively and decreased over the prior quarter due to lower production costs which offset the decline in gold production. AISC was further favorably impacted by lower sustaining capital spend as capital allocated to growth increased during the quarter.^3,4

Cash flow from operations was negative $8.1 million, a decrease of $7.5 million over the prior quarter due to lower sales partially offset by lower costs. Capital spend for the quarter was $20.8 million (net of finance leases of $6.6 million) with $9.0 million and $18.4 million in sustaining and growth capital spend, respectively. Growth capital spend included the increase in equipment fleet of $11.9 million for the open pit operations as the mine is beginning to transition from an underground/open pit operation to an open pit only operation. Free cash flow for the quarter was negative $27.9 million, compared to negative free cash flow in the prior quarter of $16.7 million due to lower cash flow from operations and higher capital spending.²

The Company announced in May 2023 that the Casa Berardi mine is beginning to transition from an underground/open pit operation to an open pit only operation. As part of that transition, the lower margin East Mine underground operations were closed in July. The better margin stopes at the underground West Mine are planned to be mined until mid-2024, at which time most underground activity will stop except exploration. To increase the productivity of the surface operations, the Company has begun insourcing with the purchase of $11.9 million of mobile mining equipment, and another $4 million is expected to be spent in the third quarter.

The Company expects to release an updated technical report in the first quarter of 2024. After closure of the underground operations in 2024, Casa Berardi will mine the 160 open pit until 2027 and is expected to be free cash flow positive. During a period of investment from 2028 to 2030, the Company expects no production while the permitting is being completed, investing in infrastructure and equipment, and exposing the first ore. Significant free cash flow is expected after 2030.

East Mine closure and June’s wildfires have reduced production guidance by about 25,000 ounces in 2023 and have increased AISC per gold ounce (after by-product credits) guidance by approximately $200 per ounce. For further details, see the Guidance section of this release.

Keno Hill - Yukon Territory

At Keno Hill, the mill restarted and began processing lower grade, stockpiled ore in June, producing 184,264 ounces of silver for the quarter The mill operated as expected at 330 tpd, which is 73% of projected year-end throughput, processing stockpiled, lower-grade ore of 17 ounces per ton (“opt”). The mine advanced the primary development sufficiently to initiate ore mining. The mill reconciled well to the model in the quarter with slightly fewer tons and better grades resulting in the expected silver and lead content with more zinc. Silver production is expected to exceed 2.5 million ounces in 2023.

Capital spend during the quarter was $3.4 million (net of $6.7 million in finance leases), and included mine development, surface infrastructure projects, and mill upgrades. Keno Hill will be included in silver operations reporting by the end of the year.

EXPLORATION AND PRE-DEVELOPMENT

Exploration and pre-development expenses totaled $6.9 million for the second quarter and $11.9 million for the first half of the year. Exploration activities during the quarter primarily focused on underground targets at Greens Creek, and Keno Hill. Highlights include:

Keno Hill: Exploration drilling discovered high-grade mineralization in the Bermingham Townsite vein located within 500 feet of planned mine infrastructure.
Greens Creek: Exploration and definition drilling continued to define and expand mineralization on strike of current mineralization with strong assay results from four targeted areas.

Keno Hill, Yukon Territory

At Keno Hill, $3.7 million of exploration is expected for the year. This quarter’s focus is on extending mineralization and resource conversion at the high-grade Bear Zone and defining new mineral resources at the Townsite Zone. During the first half, one underground drill completed over 11,000 feet of definition drilling, while two surface core drills completed over 13,000 feet of exploration drilling targeting the Bear and Townsite zones.

Bear Zone: Definition drilling targeted extending the Bear Zone to the North towards the Ruby Fault, which is interpreted to constrain mineralization of both the Bermingham Main and Bear veins. At the Bear vein, drilling results suggest that grade continues and strengthens outside the currently programmed stopes and is open for expansion. Highlights include:

44.9 oz/ton silver, 1.7% lead, and 0.8% zinc over 11.1 feet
120.9 oz/ton silver, 1.5% lead, and 3.3% zinc over 2.8 feet
47.5 oz/ton silver, 0.8% lead, and 0.2% zinc over 7.8 feet
79.4 oz/ton silver, 3.0% lead, and 1.3% zinc over 6.1 feet

Townsite Zone: High-grade mineralization was discovered in the Townsite vein approximately 2,000 feet southwest of the historical Townsite Mine stopes, and at a depth of 1,300 feet. This high-grade mineralization is open for expansion and continues to confirm the exploration potential within the district. Assay results to date include:

25.5 oz/ton silver, 0.9% lead, and 0.3% zinc over 9.2 feet, including 108.2 oz/ton silver, 4.5% lead, and 1.0% zinc over 1.7 feet

Greens Creek, Alaska

At Greens Creek, $8.0 million of exploration is focused on expanding mineralization both from surface and underground. Four underground core drills completed over 70,000 feet of drilling in 132 holes focused on resource conversion in the 200 South, East, Gallagher, Upper Plate, 9A, and West ore zones and exploration targeting the southern extensions of the 200 South, and Gallagher zones. Additionally, two helicopter supported core drills completed over 4,000 feet of drilling in 12 holes targeting near mine extensions to the Upper Plate and East ore zones. Assay results have been received for drilling in the 200 South, East, Gallagher, Upper Plate, and West areas, and results continue to confirm and expand mineral zones. Highlights include:

200 South Zone:

17.0 oz/ton silver, 0.19 oz/ton gold, 3.3% zinc, and 1.9% lead over 8.1 feet

East Zone:

12.6 oz/ton silver, 0.05 oz/ton gold, 7.7% zinc, and 3.5% lead over 5.7 feet
20.9 oz/ton silver, 0.04 oz/ton gold, 3.4% zinc, and 2.2% lead over 3.6 feet

Gallagher Zone:

7.9 oz/ton silver, 0.22 oz/ton gold, 10.5% zinc and 4.8% lead over 45.3 feet
15.0 oz/ton silver, 0.28 oz/ton gold, 2.6% zinc, and 1.3% lead over 9.0 feet
9.8 oz/ton silver, 0.19 oz/ton gold, 10.8% zinc, and 2.9% lead over 25.7 feet
21.6 oz/ton silver, 0.07 oz/ton gold, 0.6% zinc, and 0.4% lead over 41.3 feet

Upper Plate Zone: Underground and surface drilling has expanded resources over 600 and 300 feet of strike length, respectively. Initial surface drillholes completed to date have intercepted significant lengths of base metal rich white ore lithologies. Assay results from these initial surface drillholes are expected in the third quarter. Results to date indicate that drilling is upgrading and expanding mineralization in the Upper Plate Zone. Highlights from this drilling include:

23.0 oz/ton silver, 0.05 oz/ton gold, 6.2% zinc and 3.1% lead over 13.2 feet
20.7 oz/ton silver, 0.06 oz/ton gold, 1.7% zinc, and 0.7% lead over 18.0 feet

West Zone: Underground drilling expanded the strike length 550 feet with strong, high-grade mineralization over significant widths. Highlights from this drilling include:

63.4 oz/ton silver, 0.84 oz/ton gold, 11.9% zinc and 3.8% lead over 15.2 feet
13.0 oz/ton silver, 0.11 oz/ton gold, 14.4% zinc, and 3.4% lead over 8.3 feet

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

2023 GUIDANCE ⁶

The Company has updated its annual gold production, cost, and capital guidance as below. There is no change to silver production guidance.

Gold production guidance for Greens Creek is increased to reflect higher gold production. Wildfires-related suspension of operations in June and the closure of the East Mine underground operations has resulted in lower expected gold production for 2023. Three-year gold production outlook has also decreased to include the closure of underground operations in mid-2024, and transition to full surface operations in 2024.

* Equivalent ounces include Lead and Zinc production

2023 Cost Outlook

At Greens Creek, guidance for cash costs, per silver ounce (net of by-products) has increased slightly to reflect lower zinc prices by-product credits due to lower zinc prices. Guidance for AISC, per silver ounce (each after by-product credits) has decreased due to higher expected gold production, and lower planned sustaining capital spend. At Lucky Friday, guidance for cash costs per silver ounce (each after by-product credits) is increased due to higher expected labor costs attributable to the CBA, and lower zinc by-product credits due to lower zinc prices. Lucky Friday guidance for AISC, per silver ounce (each after by-product credits) has been increased to reflect higher expected sustaining capital. Impact of the CBA changes on labor costs is approximately $2.5 million in 2023. Consolidated AISC per silver ounce (after by-product credits) is unchanged.

At Casa Berardi mine, increase in cash costs and AISC, per gold ounce, each after by-product credits, is primarily due to lower gold production due to wildfires-related suspension of operations in June and closure of the East Mine operations.

	Costs of Sales (million)		Cash cost, after by-product credits, per silver/gold ounce³		AISC, after by-product credits, per produced silver/gold ounce⁴

2023 Capital and Exploration Outlook

Consolidated capital guidance is increased for all operations except Greens Creek. At the Lucky Friday, increase in capital guidance is attributable to higher growth capital spend primarily related to the service hoist project, which was commissioned in early August. Increase in sustaining capital spend is attributable to increased development and timing of receipt of mobile equipment. At Keno Hill, increase in capital is attributable to mill upgrades, and increased underground development.

At Casa Berardi, the increase in capital is primarily attributable to growth capital, which comprises the addition of surface equipment fleet (approximately $16 million) and capitalization of 160 pit waste stripping costs. Sustaining capital spend at the mine is guided lower due to the allocation of stripping costs to growth capital.

Guidance for exploration and pre-development expenditures is unchanged at $32.5 million.

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 EBITDA is a non-GAAP measurement, a reconciliation of which to net income, 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.

⁽²⁾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.

⁽³⁾ Cash cost, after by-product credits, per silver and gold ounce is a non-GAAP measurement, a reconciliation of 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.

⁽⁴⁾ All-in sustaining cost (“AISC”), after by-product credits, is a non-GAAP measurement, a reconciliation of which to total cost of sales, the closest GAAP measurement, can be found at the end of the release. AISC, after by-product credits, includes total cost of sales and other direct production costs, expenses for reclamation at the mine sites and all site sustaining capital costs. AISC, after by-product credits, is calculated net of depreciation, depletion, and amortization and by-product credits. Prior year presentation has been adjusted to conform with current year presentation.

⁽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) applicable to common stockholders is a measure used by management to evaluate the Company's operating performance but should not be considered an alternative to net income (loss) applicable to common stockholders 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) applicable to common stockholders per common share provides investors with the ability to better evaluate our underlying operating performance.

Current GAAP measures used in the mining industry, such as total cost of goods sold, do not capture all the expenditures incurred to discover, develop and sustain silver and gold production. Management believes that AISC is a non-GAAP measure that provides additional information to management, investors and analysts to help (i) in the understanding of the economics of our operations and performance compared to other producers and (ii) in the transparency by better defining the total costs associated with production. Similarly, the statistic is useful in identifying acquisition and investment opportunities as it provides a common tool for measuring the financial performance of other mines with varying geologic, metallurgical and operating characteristics. In addition, the Company may use it when formulating performance goals and targets under its incentive program.

Other

⁽⁶⁾ Expectations for 2023 include silver, gold, lead and zinc production from Greens Creek, Lucky Friday, Keno Hill, and Casa Berardi converted using Au $1,800/oz, Ag $22/oz, Zn $1.15/lb, and Pb 0.90$/lb, for equivalent ounce calculations and Au $1,950/oz, Ag $24.50/oz, Zn $1.15/lb, and Pb 1.00$/lb, for by-product credit calculations. Numbers are rounded.

Such assumptions include, but are not limited to: (i) there being no significant change to current geotechnical, metallurgical, hydrological and other physical conditions; (ii) permitting, development, operations and expansion of the Company’s projects being consistent with current expectations and mine plans, including with respect to the transition of Casa Berardi from an underground/open pit operation to an open pit only operation; (iii) political/regulatory developments in any jurisdiction in which the Company operates being consistent with its current expectations; (iv) the exchange rate for the USD/CAD being approximately consistent with current levels; (v) certain price assumptions for gold, silver, lead and zinc; (vi) prices for key supplies being approximately consistent with current levels; (vii) the accuracy of our current mineral reserve and mineral resource estimates; (viii) there being no significant changes to Company plans for 2023 and beyond due to COVID-19 or any other public health issue, including, but not limited to with respect to availability of employees, vendors and equipment; (ix) the Company’s plans for development and production will proceed as expected and will not require revision as a result of risks or uncertainties, whether known, unknown or unanticipated; (x) counterparties performing their obligations under hedging instruments and put option contracts; (xi) sufficient workforce is available and trained to perform assigned tasks; (xii) weather patterns and rain/snowfall within normal seasonal ranges so as not to impact operations; (xiii) relations with interested parties, including First Nations and Native Americans, remain productive; (xiv) maintaining availability of water rights; (xv) factors do not arise that reduce available cash balances; and (xvi) there being no material increases in our current requirements to post or maintain reclamation and performance bonds or collateral related thereto.

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, including with respect to obtaining or renewing permits; (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 any of our assets; and (xi) inflation causes our costs to rise more than we currently expect. For a more detailed discussion of such risks and other factors, see the Company’s (i) 2022 Annual Report on Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on February 17, 2023. The Company does not undertake any obligation to release publicly, revisions to any “forward-looking statement,” including, without limitation, outlook, to reflect events or circumstances after the date of this presentation, or to reflect the occurrence of unanticipated events, except as may be required under applicable securities laws. Investors should not assume that any lack of update to a previously issued “forward-looking statement” constitutes a reaffirmation of that statement. Continued reliance on “forward-looking statements” is at investors’ own risk.

Non-GAAP Measures
(Unaudited)

Reconciliation of Total Cost of Sales to Cash Cost, Before By-product Credits and Cash Cost, After By-product Credits (non-GAAP) and All-In Sustaining Cost, Before By-product Credits and All-In Sustaining Cost, After By-product Credits (non-GAAP)

The tables below present reconciliations between the most comparable GAAP measure of total cost of sales to the non-GAAP measures of (i) Cash Cost, Before By-product Credits, (ii) Cash Cost, After By-product Credits, (iii) AISC, Before By-product Credits and (iv) AISC, After By-product Credits for our operations and for the Company for the three months and six months ended June 30, 2023 and 2022, the three months ended March 31, 2023 December 31, 2022, September 30, 2022 and June 30, 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. We use AISC, After By-product Credits, per Ounce as a measure of our mines' net cash flow after costs for reclamation and sustaining capital. This is similar to the Cash Cost, After By-product Credits, per Ounce non-GAAP measure we report, but also includes reclamation and sustaining capital costs. 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 with 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 reclamation and sustaining capital costs. AISC, Before By-product Credits for our consolidated silver properties also includes corporate costs for general and administrative expense and sustaining capital costs. 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.

In addition to the uses described above, 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 and 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, their 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.

(1)		Includes all direct and indirect operating costs related to the physical activities of producing metals, including mining, processing and other plant costs, third-party refining and marketing expense, on-site general and administrative costs and royalties, before by-product revenues earned from all metals other than the primary metal produced at each operation. AISC, Before By-product Credits also includes reclamation and sustaining capital costs.

(2)		AISC, Before By-product Credits for our consolidated silver properties includes corporate costs for general and administrative expense, and sustaining capital.

(3)		During the three months ended March 31, 2023, the Company completed the necessary studies to conclude usage of the F-160 pit as a tailings storage facility after mining is complete. As a result, a portion of the mining costs have been excluded from Cash Cost, Before By-product Credits and AISC, Before By-product Credits.

(4)		Other includes $354,000 and $786,000 of total cost of sales for the three and six months ended June 30, 2023, respectively, related to the environmental services business acquired as part of the Alexco acquisition.

(5)		Prior year presentation has been adjusted to conform with current year presentation to eliminate exploration costs from the calculation of AISC, Before By-product Credits as exploration is an activity directed at the Corporate level to find new mineral reserve and resource deposits, and therefore we believe it is inappropriate to include exploration costs in the calculation of AISC, Before By-product Credits for a specific mining operation.

(6)		Keno Hill is in the ramp-up phase of production and as such costs associated with ramp up at this operation which amounted to $9.4 million and $15.3 million for the three and six months ended June 30, 2023 are excluded from the calculation of total cost of sales, Cash Cost, Before By-product Credits, Cash Cost, After By-product Credits, AISC, Before By-product Credits, and AISC, After By-product Credits.

Reconciliation of Net Income (Loss) (GAAP) and Debt (GAAP) to Adjusted EBITDA (non-GAAP) and Net Debt (non-GAAP)

This release refers to the non-GAAP measures of adjusted earnings before interest, taxes, depreciation and amortization ("Adjusted EBITDA"), which is a measure of our operating performance, and net debt to adjusted EBITDA for the last 12 months (or "LTM adjusted EBITDA"), which is a measure of our ability to service our debt. Adjusted EBITDA is calculated as net income (loss) before the following items: interest expense, income and mining taxes, depreciation, depletion, and amortization expense, ramp-up and suspension costs, gains and losses on disposition of properties, plants, equipment and mineral interests, foreign exchange gains and losses, fair value adjustments, net, interest and other income, provisions for environmental matters, stock-based compensation, provisional price gains and losses, monetization of zinc hedges and adjustments of inventory to net realizable value. Net debt is calculated as total debt, which consists of the liability balances for our Senior Notes, capital leases, and other notes payable, less the total of our cash and cash equivalents and short-term investments. Management believes that, when presented in conjunction with comparable GAAP measures, adjusted EBITDA and net debt to LTM adjusted EBITDA are useful to investors in evaluating our operating performance and ability to meet our debt obligations. The following table reconciles net loss and debt to adjusted EBITDA and net debt:

Reconciliation of Net (Loss) Income Applicable to Common Stockholders (GAAP) to Adjusted Net (Loss) Income Applicable to Common Shareholders (non-GAAP)

This release refers to a non-GAAP measure of adjusted net income (loss) applicable to common stockholders and adjusted net income (loss) per share, which are indicators of our performance. 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.

Reconciliation of Cash Provided by Operating Activities (GAAP) to Free Cash Flow (non-GAAP)

This release refers to a non-GAAP measure of free cash flow, calculated as cash provided by operating activities, less additions to properties, plants, equipment and mineral interests. Management believes that, when presented in conjunction with comparable GAAP measures, free cash flow is useful to investors in evaluating our operating performance. The following table reconciles cash provided by operating activities to free cash flow:

Free cash flow	$	(27,691	)	$	5,854		$	(41,531	)	$	22,285

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.
