Exploration

Drilling at Keno Hill intersected significant widths of high-grade silver mineralization at both the Bermingham and Flame & Moth deposits, confirmed and expanded mineralization in both areas. Highlights include:
- Bermingham Bear Vein: 35.4 oz/ton silver, 2.2% lead, and 2.0% zinc over 20.2 feet.
- Flame & Moth Veins 0, 1, and Stockwork: 28.6 oz/ton silver, 3.3% lead, and 6.2% zinc over 22.3 feet.
Drilling at Greens Creek intersected strong mineralization in multiple ore zones adding confidence and expanding mineralization. Most notably, the West Zone: 72.7 oz/ton silver, 0.23 oz/ton gold, 9.6% zinc, and 5.2% lead over 26.9 feet.

* Net Leverage ratio is calculated as long-term debt and finance leases less cash to adjusted EBITDA.

"Hecla saw significant improvement in gross profit and free cash flow during the quarter - with our gross profit increasing more than 1.5 times over the prior quarter, and free cash flow generation of $28.3 million, which allowed us to reduce our net debt by $25.1 million," said Cassie Boggs, interim President and CEO. "This financial performance was driven by strong results and free cash flow generated at Greens Creek and Lucky Friday, while Keno Hill's ramp-up progressed well with throughput in excess of 400 tpd. With this strong performance and favorable price environment, we will continue our focus on reducing debt while continuing to invest in our operations and exploration programs."

Boggs continued, "At Keno Hill, while the ramp-up has gone well, our focus will be to ensure Hecla's culture of safety and environmental excellence is instilled in the operational and mining practices. As a result, we expect costs and investment at the mine will remain at current levels as more work is required to deliver long-term value. We are committed to collaborating and working with the First Nation of Na-Cho Nyäk Dun as they work through the clean-up work after the heap leach failure at Victoria Gold's Eagle Gold mine. We have offered our assistance and will continue to be available where we can during this time of crisis."

Boggs concluded, "Silver demand is projected to remain robust, supported by the growing solar demand as the world transitions to a cleaner, greener economy. With Hecla's silver production expected at about 17 million ounces this year, potentially increasing to 20 million ounces by 2026, Hecla remains the fastest growing established silver producer with growth in the best mining jurisdictions."

Sales in the second quarter increased by 30% from the prior quarter to $245.7 million due to higher quantities sold of all metals produced except zinc, as well as higher realized prices for all metals. The higher sales volumes were due to a full quarter of production at Lucky Friday, increased sales at Keno Hill and Casa Berardi, partially offset by lower volumes sold at Greens Creek.

Gross profit increased by 168% to $51.4 million, reflecting higher realized prices and higher sales volumes at Lucky Friday and Casa Berardi.

Net income applicable to common stockholders for the quarter was $27.7 million, a $33.6 million improvement from the prior quarter, primarily because of:

Ramp-up and suspension costs decreased by $9.0 million to $5.5 million, reflecting a full quarter of Lucky Friday production following the restart in January and improved performance at Keno Hill.
Fair value adjustments, net increased by $6.9 million due to unrealized gains on both our derivative contracts not designated as accounting hedges, and marketable equity securities portfolio.

The above items were partly offset by:

Income and mining tax provision increased by $7.3 million to $9.1 million reflecting higher taxable income of our US operations.
General and administrative costs increased by $3.5 million due to costs incurred related to the former CEO's retirement, which were primarily non cash equity compensation costs.

Consolidated silver total cost of sales in the second quarter increased by 14% to $123.3 million, reflecting a full quarter of production at Lucky Friday and increased sales at Keno Hill. Consolidated cash costs and AISC per silver ounce, each after by-product credits, were $2.08 and $12.54 respectively and only include costs of Greens Creek and Lucky Friday for the full quarter (commercial production has not been declared at Keno Hill). The decrease in cash costs and AISC per silver ounce was due to higher silver production and higher by-product credits partially offset by higher production costs.^3,4

Consolidated gold total cost of sales were $67.3 million, reflecting an increase in sales volumes at Casa Berardi. Cash costs and AISC per gold ounce, each after by-product credits, were $1,701 and $1,825, respectively.^3,4 The increase in cash costs per ounce was attributable to higher contractor, maintenance and consumables costs partially offset by higher gold production at Casa Berardi, with AISC also impacted by lower sustaining capital.

Adjusted EBITDA for the quarter was a record $90.9 million, an increase of $18.2 million primarily due to higher gross profit for the reasons mentioned above.⁵ The net leverage ratio improved to 2.3 from 2.7 in the prior quarter due to higher adjusted EBITDA and a reduction in net debt of $25.1 million as the Company decreased borrowings under its revolving credit facility.⁵ Cash and cash equivalents at the end of the quarter were $24.6 million and included $62.0 million drawn on the revolving credit facility. Borrowing on the revolving credit facility decreased by $78 million in the quarter as the Company utilized free cash flow and insurance proceeds to reduce the drawn amount. At current price levels and expected production, the Company anticipates the net leverage ratio to return to the Company's target of less than 2.0 by the end of the year 2024.⁵

Cash provided by operating activities was $78.7 million and increased by $61.6 million due to an increase in net income adjusted for non-cash items of $32.3 million and a favorable working capital change of $29.3 million.

Capital expenditures of $50.4 million increased by $2.8 million from the prior quarter. Capital investments at the operations were as follows (i) $11.7 million at Greens Creek related to development, equipment purchases and surface projects, (ii) $12.4 million at Casa Berardi, primarily related to tailings construction activities, (iii) $10.8 million at Lucky Friday primarily related to development, pre-production drilling, and equipment purchases, and (iv) $14.5 million at Keno Hill, related to underground development, mobile equipment purchases, and camp expansion.

Free cash flow for the quarter was $28.3 million, compared to negative $30.5 million in the prior quarter.² The improvement in free cash flow was attributable to a full quarter of Lucky Friday production and improved performance at Keno Hill which led to higher sales volumes and realized prices.

Forward Sales Contracts for Base Metals and Foreign Currency

The Company uses financially settled forward sales contracts to manage exposure to zinc and lead price changes in forecasted concentrate shipments. On June 30, 2024, the Company had contracts covering approximately 7% and 34% of the forecasted payable zinc and lead production, respectively, through 2026, at an average zinc price of $1.37 per pound and a lead price of $0.99 per pound.

The Company also manages Canadian dollar ("CAD") exposure through forward contracts. At June 30, 2024, the Company had hedged approximately 54% of forecasted Casa Berardi and Keno Hill CAD- denominated direct production costs through 2026 at an average CAD/USD rate of 1.33. The Company has also hedged approximately 21% of Casa Berardi and Keno Hill's projected CAD-denominated total capital expenditures through 2026 at 1.35.

Greens Creek produced 2.2 million ounces of silver during the quarter, a decrease of 9% compared to the prior quarter, primarily due to lower mined grades which reverted to plan. Throughput for the quarter averaged 2,481 tpd, a decline of 3% as multiple mill maintenance projects including installation of a new primary screen, relining of the grinding circuit, and concentrate thickener rake replacement, were completed during the quarter. By-product metal production was lower primarily due to lower grades.

Sales in the quarter were $95.7 million, a 2% decrease due to lower quantities of all metals sold, partially offset by higher realized prices. Lower sales volumes were also attributable to an increase in silver and zinc concentrate inventory due to the timing of shipments at quarter end. Total cost of sales decreased to $56.8 million, reflecting lower sales volumes. Cash costs and AISC per silver ounce, each after by-product credits, were $0.19 and $5.40, respectively, and decreased over the prior quarter due to lower treatment charges and higher by-product credits (higher realized prices for by-products offset lower production volumes).^3,4

Cash flow from operations was $43.3 million, an increase of $14.6 million, primarily due to higher realized prices. Free cash flow for the quarter was $33.6 million, an increase of $13.2 million, as higher cash flow from operations was partially offset by planned higher capital investment during the quarter.

Lucky Friday produced 1.3 million ounces of silver, the highest quarterly production since 2000 and an increase of 23% over the prior quarter, reflecting a full quarter of production. Mill throughput of 1,181 tpd also set a record in the mine's 80-year history.

Sales in the second quarter were $59.1 million, and total cost of sales were $37.5 million, compared to $35.3 million and $27.5 million, respectively in the prior quarter, reflecting higher sales volumes and realized prices. Cash costs and AISC per silver ounce, each after by-product credits, were $5.32 and $12.74 respectively, and were lower due to higher production, but higher than guidance due to higher labor and contractor costs, and higher profit sharing (under the collective bargaining agreement) reflecting the strong performance and higher realized prices.

Cash flow from operations was $44.5 million and includes $17.8 million in insurance proceeds received during the quarter, as well as positive working capital adjustments due to ramp-up being achieved in the prior quarter.

Capital expenditures for the quarter were $10.8 million, and included capital development, mobile equipment purchases, and completion of the rehabilitation work related to the secondary egress (#2 shaft). Free cash flow for the quarter was $33.7 million, an increase of $21.6 million reflecting a full quarter of operations and the collection of $17.8 million of insurance proceeds.² The Company's underground insurance sublimit coverage is $50 million, of which $35.2 million has been received to date and the Company expects to receive the remaining $14.8 million in insurance proceeds before the end of the year.

At Keno Hill, ramp-up continued and the mine produced 900,440 ounces of silver in the second quarter, a record for the operation, and an increase of 39% over the prior quarter. Throughput in the quarter averaged 406 tpd, an increase of 47%, partially offset by lower silver grades, which were 25.1 ounces per ton. Production commenced from the Flame & Moth deposit at the beginning of July and is expected to supplement ore production from the Bermingham deposit.

Sales during the quarter were $29.0 million, an increase of $18.1 million over the prior quarter due to a combination of higher realized prices and volumes. Ramp-up costs during the quarter were $1.8 million and are included in ramp-up and suspension costs on the consolidated statement of operations. Expenditures on production costs, including ramp-up costs (excluding depreciation), totaled $27.4 million for the quarter, higher than the guidance of $15-$17 million per quarter due to increased production volumes and throughput. Capital investments during the quarter were $14.5 million for underground and surface infrastructure projects including camp expansion, mine development, and mobile equipment purchases.

The Company continues to make progress on the cemented tails batch plant, a critical infrastructure project, which will facilitate a change in the mining method at the Bermingham deposit to underhand mining, which should improve safety and productivity. Construction of the project is expected to be completed in the fourth quarter with full conversion to underhand mining expected by the end of 2025. Other key capital projects in progress are expansion of camp facilities, water treatment plant upgrades, and key equipment purchases.

Keno Hill's AIFR, one of several improving measures, improved 12% to 1.98. As the Keno Hill operation moves towards full production, the Company expects sustained investment in long-term infrastructure to support sustainable and safe mining operations throughout the current reserve mine plan of eleven years. Continued focus on safety, environmental, permitting, and mining practices, and relations with First Nation of Na-Cho Nyäk Dun are key to maintaining and increasing production levels and delivering long-term value at this operation.

Casa Berardi produced 23,187 ounces of gold in the quarter, an increase of 5% over the prior quarter as a 7% increase in throughput and recoveries were offset by lower grades from the 160 pit. The mill operated at an average of 4,194 tpd during the quarter.

Sales were $58.6 million, a 41% increase due to a combination of higher sales volumes and realized prices. Total cost of sales were $67.3 million, a 16% increase compared to the prior quarter, attributable to higher sales volumes and higher costs. Cash costs and AISC per gold ounce, each after by-product credits increased to $1,701 and $1,825, respectively, primarily due to higher production costs attributable to higher contractor costs and consumables (higher volumes). AISC was favorably impacted by planned lower sustaining capital spend. ^3,4

Cash flow from operations was $17.8 million, an increase of $14.6 million over the prior quarter. Capital investments for the quarter totaled $12.4 million ($2.7 million in sustaining and $9.7 million in growth) and were primarily related to construction costs for tailings facilities. Free cash flow for the quarter was $5.8 million and improved by $15.2 million from the prior quarter due to higher cash flow from operations and lower capital spending.²

With the increase in gold prices, the Company has completed a stope-by-stope analysis of the west mine underground operations and is extending the underground operations for the remainder of 2024. Please refer to the guidance section of the release for updated production guidance for the mine.

EXPLORATION AND PRE-DEVELOPMENT

Exploration and pre-development expenses totaled $6.7 million for the quarter. Exploration activities during the quarter primarily focused on underground definition and exploration drilling at Greens Creek, Keno Hill, and Casa Berardi.

Keno Hill

At Keno Hill, underground drilling during the first half of 2024 continued to intersect high-grade silver mineralization over significant widths and highlights the potential for high-grade silver mineralization in the district. Underground definition drilling is focused on extending mineralization and resource conversion in the high-grade Bermingham Bear Zone veins (Bear, Footwall, and Main Vein zones) and in the Flame & Moth veins. During the quarter, two underground drills completed over 13,000 feet of definition drilling. Three surface drills were also active on the property testing multiple targets including the Bermingham Deep, Bermingham Townsite, Elsa17-Dixie, and Silver Spoon target areas that have potential for the discovery of additional large high-grade silver deposits. Over 25,000 feet of surface exploration drilling has been completed in 13 drillholes.

Assay highlights include (reported widths are estimates of true width):

Bear Vein: 35.4 oz/ton silver, 2.2% lead, and 2.0% zinc over 20.2 feet
- Includes: 150.8 oz/ton silver, 9.9% lead, and 4.8% zinc over 3.0 feet
Main Vein: 29.8 oz/ton silver, 1.6% lead, and 0.2% zinc over 10.3 feet
- Includes: 86.0 oz/ton silver, and 8.0% lead over 0.8 feet.
- Includes: 203.9 oz/ton silver, 8.4% lead, and 0.1% zinc over 0.9 feet
Flame & Moth Veins 0, 1, Stockwork: 28.6 oz/ton silver, 3.3% lead, and 6.2% zinc over 22.3 feet
- Includes: 129.8 oz/ton silver, 5.7% lead, and 6.6% zinc over 1.7 feet
- Includes: 35.1 oz/ton silver, 6.6% lead, and 10.6% zinc over 7.4 feet

Greens Creek

At Greens Creek, three underground drills completed over 44,000 feet of drilling focused on resource conversion and exploration to extend mineralization of known resources. Drilling was focused in the 9a, 200 South, 5250, NWW, West, Gallagher, and Southwest Bench areas. In addition, two helicopter-supported surface exploration drills completed over 8,000 feet of drilling (assays pending) focused on expanding the Upper Plate Zone to the west of current resources and drill testing the Mammoth target.

Assay highlights include (reported widths are estimates of true width):

NWW Zone: 32.0 oz/ton silver, 0.18 oz/ton gold, 14.2% zinc, and 5.0% lead over 19.3 feet
200 South Zone: 15.7 oz/ton silver, 0.02 oz/ton gold, 2.0% zinc, and 1.0% lead over 26.9 feet
West Zone: 72.7 oz/ton silver, 0.23 oz/ton gold, 9.6% zinc, and 5.2% lead over 26.9 feet

At Casa Berardi, underground drilling is continuing to evaluate the remaining underground stopes and mineral zone extensions.

2024 GUIDANCE ⁶

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

2024 Production Outlook

Gold production guidance for Casa Berardi is increased to reflect the extension of underground operations until the end of the year 2024.

	Silver Production (Moz)	Gold Production (Koz)		Silver Equivalent (Moz)		Gold Equivalent (Koz)
	Current	Previous	Current	Previous	Current	Previous	Current

*Equivalent ounces include lead and zinc production

2024 Cost Outlook

At Greens Creek, guidance for cash costs and AISC per silver ounce, each after by-product credits, has decreased to reflect higher by-product credits (due to strong realized prices), and strong silver production. AISC per silver ounce, after by-product credits, is also favorably impacted by lower expected capital investment during the remaining year.

At Lucky Friday, guidance for cash costs and AISC per silver ounce, each after by-product credits, has increased to reflect higher labor and contractor costs incurred through the first half of 2024, and expected higher profit sharing costs (under the collective bargaining agreement) during the remaining year attributable to higher prices.

At Keno Hill, expenditures on production costs, excluding depreciation, are expected to be $25-$27 million per quarter for the remaining year to reflect current levels of expenditures associated with the increase in production volumes.

For Casa Berardi, cost of sales guidance is increased to include expected underground production costs for the rest of 2024. Cash costs and AISC, per gold ounce, each after by-product credits is unchanged as the increased costs are offset by higher expected production.

	Costs of Sales (million)		Cash cost, after by-product credits, per silver/gold ounce³		AISC, after by-product credits, per produced silver/gold ounce⁴
	Previous	Current	Previous	Current	Previous	Current
Greens Creek	252	252	$3.50 - $4.00	$2.25 - $3.00	$9.50 - $10.25	$8.25 - $9.00

2024 Capital and Exploration Guidance

The Company is increasing capital guidance for the year to reflect higher expected capital investment at Keno Hill, partially offset by lower capital investment at Greens Creek. At Greens Creek, capital investment guidance is reduced to reflect lower capital investment through the first half of the year and timing of equipment purchases and capital projects.

At Keno Hill, increase in capital investment guidance is primarily attributable to increased underground development, water treatment plant upgrades, camp expansion, equipment purchases, and cemented tails batch plant.

Exploration and pre-development guidance 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⁾ 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.

⁽²⁾ Free cash flow is a non-GAAP measure calculated as cash provided by operating activities less capital expenditures. 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. Capital expenditures refers to Additions to properties, plants and equipment from the Consolidated Statements of Cash Flows, net of finance leases.

⁽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. 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 in 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 EBITDA is a non-GAAP measurement, a reconciliation of which to net 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 loss, 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.

⁽⁶⁾ Expectations for 2024 include silver, gold, lead, and zinc production from Greens creek, Lucky Friday, Keno Hill, and Casa Berardi converted using gold $1,950/oz, silver $22.50/oz, zinc $1.20/lb, and lead $0.95/lb. Numbers are rounded.

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.

Information regarding data verification, surveys and investigations, quality assurance program and quality control measures and a summary of analytical or testing procedures for (i) the Greens Creek Mine are contained in its Technical Report Summary and in a NI 43-101 technical report titled “Technical Report for the Greens Creek Mine” effective date December 31, 2018, (ii) the Lucky Friday Mine are contained in its Technical Report Summary and in its technical report titled “Technical Report for the Lucky Friday Mine Shoshone County, Idaho, USA” effective date April 2, 2014, (iii) Casa Berardi are contained in its Technical Report Summary and in its NI 43-101 technical report titled “Technical Report on the Casa Berardi Mine, Northwestern Quebec, Canada” effective date December 31, 2023 and (iv) Keno Hill are contained in its Technical Report Summary and in its NI 43-101 technical report titled “Technical Report on the Keno Hill Mine, Yukon, Canada” effective date December 31, 2023. Also included in each technical report is a description of the key assumptions, parameters and methods used to estimate mineral reserves and resources and a general discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant factors. Mr. Allen and Mr. Blair reviewed and verified information regarding drill sampling, data verification of all digitally collected data, drill surveys and specific gravity determinations relating to all the mines. The review encompassed quality assurance programs and quality control measures including analytical or testing practice, chain-of-custody procedures, sample storage procedures and included independent sample collection and analysis. This review found the information and procedures meet industry standards and are adequate for Mineral Resource and Mineral Reserve estimation and mine planning purposes.

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 ended June 30, 2024, March 31, 2024, December 31, 2023, September 30, 2023, June 30, 2023 and the six months ended June 30, 2024 and 2023.

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. 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 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. 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 unit 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.
