TORONTO, Nov. 10, 2026 (GLOBE NEWSWIRE) -- Discovery Mining Ltd. (TSX: DSV, OTCQX: DSVSF) (“Discovery” or the “Company”) today announced financial and operating results for the third quarter (“Q3 2026”) and first nine months (“YTD 2026”) of 2026. Q3 2026 includes the first full quarter of results from the Kidd Operations, which were acquired on June 1, 2026. All amounts are in US dollars, unless otherwise noted.

Tony Makuch, Discovery’s President, CEO & Chairman, commented: “Q3 2026 was a critical quarter of accomplishment for Discovery, highlighted by record gold production and sales, solid earnings and strong cash flow. Our cash increased 24%, reaching $450.7 million at September 30, 2026. We generated over $200 million of operating cash flow and $87 million of free cash flow during a quarter when we invested close to $120 million of cash for capital expenditures aimed at supporting our growth and business improvements. Our ability to generate cash that enhances our financial position and supports our investment programs is an important competitive strength that will benefit us moving forward.

“Another key competitive strength is our continued exploration success at Porcupine. Last quarter, we discussed the evolving transformation of Pamour, which has been established over a 4 km strike length and where high-grade zones have been identified in multiple target areas. We recently issued additional drill results from Pamour that demonstrated strong continuity of the gold-bearing structures, including in the key area between Pamour and Pamour West. We also recently released encouraging drill results at Dome, which included identifying new areas of mineralization to the north, and extending mineralization to the south by 600 metres. With these results, we now believe Dome is an open-pit project that, like Pamour, has the potential to become substantially larger and more valuable than previously envisioned. Dome remains open to the north, south and west, with potential to extend into the neighbouring Paymaster property. Speaking of Paymaster, through the acquisition of certain mineral properties from McEwen Inc. in October, we now have 100% ownership in Paymaster.

“Q3 2026 was also an important quarter for Cordero, our large-scale silver project in Mexico. We obtained the Change of Land Use permit on September 28, 2026, with approval of the Environmental Impact Assessment (“MIA”) being received on October 5th. Receiving these approvals completes the Federal environmental permitting process and positions Cordero to advance towards development. We are updating the 2024 feasibility study capital and cost estimates, with an update to be released over the next few months.

“Looking ahead, we are well positioned to end the year with a strong fourth quarter and remain on track to issue an updated technical report for Porcupine early in 2027.”

(2) Gold sold includes ounces delivered in-kind under the Franco Nevada royalty arrangement.
(3) Gold AISC refers to all-in sustaining costs and excludes share-based compensation costs.

Discovery began reporting the results of gold production and sales following the Company’s acquisition (“Porcupine Acquisition”) of the Porcupine Complex (“Porcupine”) in and near Timmins, Ontario on April 15, 2025.

The Company began reporting results for the Kidd Operations, including the Kidd Creek Mine and Kidd Metallurgical Site, following their acquisition on June 1, 2026.

Q3 2026

  • Revenue of $371.4 million, of which $299.1 million related to gold sales from the Porcupine Operations, with the remainder from concentrate sales related to the Kidd Operations. Gold revenue compared to $237.0 million in Q3 2025 and $289.4 million the previous quarter, with the 26% increase from Q3 2025 resulting from a 3% increase in gold sales and a 23% improvement in the average realized gold price.
  • Netearnings totaled $58.4 million ($0.07 per basic share) compared to net earnings of $42.4 million ($0.05 per basic share) in Q3 2025 and net earnings of $52.1 million ($0.06 per basic share) the previous quarter.
  • Adjustednetearnings(1) totaled $83.0 million ($0.10 per basic share) versus $61.1 million ($0.08 per basic share) in Q3 2025 and $92.3 million ($0.11 per basic share) the previous quarter. The $24.6 million difference between net earnings and adjusted net earnings in Q3 2026 largely reflected the after-tax impact of excluding from adjusted net earnings $19.3 million of share-based compensation costs (related to the impact of significant share-price appreciation on the mark-to-market value of long-term incentive awards), as well as the impact of purchase price allocations (“PPA”) adjustments, foreign exchange loss, and Transition Services Agreement costs related to the Porcupine Acquisition.
  • EBITDA(1)(2) totaled $181.4 million, a 49% increase from $122.1 million in Q3 2025 and 7% higher than $170 million the previous quarter.
  • Keyoperating results: 
    • Record gold production of 70,564 ounces, a 12% increase from 63,154 ounces in Q3 2025 and 5% higher than 67,309 ounces in Q2 2026
    • Record gold sold(3) of 71,200 ounces compared to 69,004 ounces in Q3 2025 and 66,068 ounces the previous quarter.
    • Total gold production costs of $97.6 million versus $106.8 million in Q3 2025 (including $18.5 million of PPA adjustments) and 89.7 million in Q2 2026;
    • Operating cash costs(1) of $1,470 per ounce sold compared to $1,339 per ounce sold in Q3 2025 and $1,387 per ounce sold in Q2 2026, with the increase from both prior periods largely related to higher-cost tonnes processed from stockpiles during Q3 2026.
    • Site-level AISC(1)(4)(5) of $2,123 per ounce sold versus $1,699 per ounce sold in Q3 2025 and $2,028 per ounce sold the previous quarter, with higher operating cash costs and sustaining capital expenditures largely accounting for the increases from both prior periods
    • AISC(1)(5) of $2,293 per ounce sold compared to AISC of $1,734 per ounce sold in Q3 2025 and $2,154 per ounce sold the previous quarter.
  • Capital expenditures(1) totaled $139.1 million, compared to $65.2 million in Q3 2025 and $86.4 million in Q2 2026. Included in the $139.1 million in Q3 2026 were $42.0 million of sustaining capital expenditures, largely related to mobile equipment purchases at Borden, investments at the Dome Mill and work to buttress the No. 6 tailings management area (“TMA6”), and $97.1 million of growth capital expenditures(1) (including $6.9 million of capitalized exploration), mainly for increasing capacity and implementing a new deposition strategy at the TMA6 and for continued pre-stripping at Pamour.
  • Net cash generated from operating activities in Q3 2026 totaled $203.3 million compared to net cash from operating activities of $153.5 million in Q3 2025 and net cash from operating activities of $74.0 million the previous quarter. Net cash from operating activities before changes in working capital totaled $146.8 million versus $82.0 million in Q3 2025 and $130.0 million in Q2 2026. A $56.5 million favourable impact from working capital changes in Q3 2026 compared to a $56.1 million unfavourable impact in Q2 2026, with the change reflecting the normalization of accounts payable following accelerated payments made in Q2 2026 as part of the implementation of a new enterprise resource planning ("ERP") system, partially offset by higher accounts receivable related to the timing of collections on Kidd concentrate sales.
  • Free cash flow(1) in Q3 2026 totaled $86.9 million, unchanged from $86.8 million in Q3 2025 and compared to free cash outflow of $11.4 million the previous quarter, with the favourable impact of increased net cash from operating activities more than offsetting significantly higher capital expenditures in accounting for the quarter-over-quarter improvement.
  • Cash at September 30, 2026, totaled $450.7 million compared to $364.3 million at June 30, 2026, and $410.7 million at December 31, 2025, with the increase in cash from June 30, 2026 resulting mainly from higher net cash from operating activities during the quarter.
  • Working capital(1) at September 30, 2026, totaled $265.0 million compared to working capital of $224.2 million at September 30, 2025, and $270.7 million at June 30, 2026.

YTD 2026

  • Gold production totaled 198,142 ounces compared to 113,706 ounces for YTD 2025, while gold sales totaled 196,714 ounces. Revenue totaled $975.5 million ($873.5 million from Porcupine Operations), which compared to $379.0 million for YTD 2025 representing revenue generated from the closing of the Porcupine Acquisition on April 15, 2025, through September 30, 2025. Production costs totaled $327.5 million for YTD 2026 compared to $161.7 million for YTD 2025. Gold operating cash costs averaged $1,426 per ounce sold, while gold AISC per ounce sold averaged $2,170, compared to $1,340 per ounce sold and $1,863 per ounce sold, respectively, for YTD 2025.
  • Net earnings totaled $192.3 million, or $0.24 per basic share. YTD 2026 net earnings compared to net earnings of $41.5 million, or $0.06 per basic share, in YTD 2025.
  • Adjusted net earnings totaled $258.1 million ($0.32 per basic share) compared to $86.5 million ($0.13 per basic share) for YTD 2025. The difference between net earnings and adjusted net earnings for YTD 2026 mainly reflected the after-tax impact of excluding from adjusted net earnings $19.7 million of deferred tax expense, $19.3 million of share-based compensation costs related to the mark-to-market value of long-term incentive awards, PPA adjustments, Transition Services Agreement costs, and a payment to First Nations in connection with the closing of the Kidd Transaction.
  • EBITDA was $529.3 million versus $171.0 million in YTD 2025.
  • Net cash generated from operating activities totaled $320.2 million compared to net cash generated from operating activities of $214.5 million for YTD 2025.
  • Total capital expenditures totaled $295.4 million, which included $99.0 million of sustaining capital expenditures and $196.4 million of growth capital expenditures (including $20.8 million of capitalized exploration). Of the $196.4 million of growth capital expenditures for YTD 2026, $176.7 million related to Porcupine largely for pre-stripping at Pamour and longer-term investments at the TMA6.

Gold production at the Porcupine Operations in Q3 2026 totaled 70,564 ounces, a 12% increase from 63,154 ounces in Q3 2025 and 5% higher than 67,309 ounces the previous quarter. The 70,564 ounces in the quarter resulted from 943,761 tonnes being processed at an average grade of 2.61 g/t, with recovery rates averaging 89.0%, which compared to 808,688 tonnes at an average grade of 2.69 g/t and recovery rates averaging 90.3% in Q3 2025, and 904,244 tonnes at an average grade of 2.57 g/t and recovery rates averaging 90.2% in the previous quarter. The increase in production in Q3 2026 compared to both prior periods was driven by higher tonnes processed, which increased 17% and 4% from Q3 2025 and Q2 2026, respectively.

Mined tonnes in Q3 2026 increased 9% from the previous quarter, to 1,210,118 tonnes. At September 30, 2026, there was more than 1.7 million tonnes of stockpiled material. Mining costs per ore tonne improved compared to both Q3 2025 and the previous quarter, reflecting lower mining costs per tonne at Pamour, which more than offset higher mining costs per tonne at Hoyle Pond.

Mill operating costs per tonne processed improved during Q3 2026, averaging $20.1 per tonne compared to $21.2 per tonne in Q3 2025 and $21.5 per tonne the previous quarter, with the improvement from Q2 2026 mainly related to higher processing volumes and lower total mill operating costs. Based on full operating days, Dome Mill's processing capabilities continued to achieve significant improvement with daily throughput exceeding 11,000 tonnes per day on 48 days in Q3 2026, including 16 days when the mill achieved the operating capacity of over 12,000 tonnes per day.

Total production costs in Q3 2026 were $97.6 million versus $106.8 million in Q3 2025 (including $18.5 million of purchase price allocation adjustments on inventory related to the Porcupine Acquisition) and $89.7 million the previous quarter. Gold operating cash costs(1) per ounce sold averaged $1,470 compared to $1,339 in Q3 2025 and $1,387 the previous quarter, largely reflecting the impact of higher cost tonnes from inventory processed during the quarter compared to both prior periods. Site-level gold AISC(1)(2) averaged $2,123 per ounce sold compared to $1,699 in Q3 2025 and $2,028 in Q2 2026. The increase in gold AISC compared to both periods reflected higher operating cash costs and sustaining capital expenditures(1). Sustaining capital expenditures in Q3 2026 mainly related to mobile equipment purchases at Borden, investments at the Dome Mill and work to buttress the TMA6 at the Dome property.

For YTD 2026, a total of 198,142 ounces of gold were produced, which resulted from 2,546,989 tonnes being processed at an average grade of 2.69 g/t, with recovery rates averaging 89.9%. Total mill operating costs were $55.8 million for YTD 2026, for an average of $21.9 per tonne processed.

KIDD OPERATIONS REVIEW

Discovery's Kidd Operations consist of the Kidd Creek Mine, an underground copper, zinc and silver mining operation, the Kidd Met Site, a large-scale processing facility that includes four concentrator circuits, tailings infrastructure and related operating assets, and a large exploration land position north of Timmins held through Kidd Creek Timber Ltd. Current operations consist of underground mining at the Kidd Creek Mine, with ore transported by rail for processing into copper and zinc concentrate at the Kidd Met Site. The Company is currently evaluating the construction of a new conventional gold circuit at the Kidd Met Site, as well as other modifications to support gold production from different kinds of mineralization. The upgrading and expansion of the Kidd Met Site, together with the site's surface rights contiguous to Hoyle Pond and Pamour, and tailings, power and other infrastructure is expected to support the planned future growth of Discovery's gold operations. Comparative information for Q3 2025 and YTD 2025 is not presented for the Kidd Operations, as the Company acquired the Kidd Operations on June 1, 2026. YTD 2026 results reflect the Kidd Operations from the Acquisition Date.

In Q3 2026, a total of 283,763 ore tonnes were processed at the Kidd Met Site, resulting in the production of concentrate of 3,644 tonnes of copper (average grade of 1.34% and average recoveries of 96.2%) and 5,491 tonnes of zinc (average grade of 2.25% and average recoveries of 85.9%), compared to 102,839 ore tonnes processed resulting in the production of concentrate of 1,286 tonnes of copper (average grade of 1.30% and average recoveries of 96.1%) and 3,361 tonnes of zinc (average grade of 3.63% and average recoveries of 89.9%) for the period from June 1 to June 30, 2026.

A total of 3,349 tonnes and 4,589 tonnes for copper and zinc were sold during Q3 2026, compared to 1,230 tonnes and 2,967 tonnes for the partial period in Q2 2026.

Revenue at Kidd from copper and zinc concentrates sales totaled $72.3 million, while production costs totaled $45.1 million, compared to revenue of $29.7 million and production costs of $18.9 million in Q2 2026. Cash costs for copper averaged $3.21 per pound sold, while cash costs for zinc averaged $1.36 per pound sold in Q3 2026, compared to $1.29 per pound sold for copper and $0.84 per pound sold for zinc in Q2 2026. Silver sales, which are treated as by-product credits attributable to copper, totaled $7.9 million in Q3 2026, compared to $5.3 million the previous quarter. The concentrate payment process operates on specified time intervals based on the terms of off-take agreements. In the case of the Kidd Operations, existing off-take terms result in longer periods for cash collection on outstanding receivables as compared to the Company’s gold business.

CORDERO OVERVIEW

The Cordero Project was acquired by Discovery in 2019. Since that time, the Company has invested over $100.0 million in Mexico, conducting significant exploration drilling and technical analysis, leading to the release of multiple studies, most recently the FS dated February 16, 2024, and filed on SEDAR+ (www.sedarplus.ca) on March 28, 2024. The results of the FS confirmed Cordero to be one of the world’s largest undeveloped silver deposits, with the potential for large-scale production at low unit costs, and capable of generating substantial free cash flow and attractive economic returns. Since the filing of the FS, the Company has continued to advance work at the Cordero property, engaging in community and government relations as well as other activities that further de-risk the project. The Company achieved a major milestone for the Cordero Project with the receipt of the Change of Land Use permit from SEMARNAT on September 28, 2026, followed by approval of the MIA permit on October 5, 2026. Together, these complete the federal environmental permitting process and position the Company to advance Cordero towards development.

Key highlights of the FS include:

  • Average annual production of 37.0 million silver equivalent ounces(1) (“AgEq”) over the first 12 years with a total project life of 19 years;
  • AISC(2) averaging below $12.50 per AgEq ounce in Years 1 – 8;
  • Base-case after-tax net present value (“NPV”) of $1.2 billion (Base-case metal prices: Silver – $22.00 per ounce; Gold – $1,600 per ounce; Zinc – $1.20 per pound; Lead – $1.00 per pound);
  • Initial capital expenditures(2) of $606.0 million (resulting in an NPV to capital ratio of 2:1);
  • Large-scale Mineral Reserves totaling 302 million ounces of silver, 840,000 ounces of gold, 5.2 billion pounds of zinc and 3.0 billion pounds of lead;
  • Important socio-economic contribution to Mexico, including an initial investment of over $600 million, the creation of 2,500 jobs during development, and over 1,000 jobs during operations, $4.0 billion in total procurement, all to remain within Mexico, and, assuming a fixed $35.00 per ounce silver price, total tax contributions within Mexico of $2.4 billion over the project life; and,
  • High levels of environmental responsibility and a commitment to contributing to the management of key social issues such as carbon reduction and water quality and availability.

Third Quarter 2026 Highlights

During Q3 2026, there were a number of key developments in support of advancing the Cordero Project towards development, including:

  • Receiving the Change of Land Use permit (MIA approval received on October 5, 2026);
  • Progressed work on updating the February 2024 Feasibility Study capital and operating cost estimates to reflect the current pricing environment;
  • Engaged a third-party specialist power consultant and commenced work on the development schedule and capital cost update to establish natural gas power at site, in an effort to reach a decision point in 2026 on the selection of either natural gas power or grid power as the primary source of power for Cordero;
  • Advanced discussions with water treatment plant operators on the planned upgrade and operation of the local water treatment plant; and,
  • Advanced work on finalizing the development schedule and financing strategy for Cordero.

(1) AgEq Produced is metal recovered in concentrate. AgEq is calculated as Ag + (Au x 72.7) + (Pb x 45.5) + (Zn x 54.6); these factors are based on metal prices of Ag - $22/oz, Au - $1,600/oz, Pb - $1.00/lb and Zn - $1.20/lb.

Discovery’s full-year guidance for 2026 was announced in a press release dated February 19, 2026. With the exception of Cordero - Fees and capital and Corporate G&A costs, discussed below, the Company's guidance remained unchanged as of September 30, 2026. Discovery's Kidd Operations, acquired on June 1, 2026, are not included in the 2026 guidance.

Gold Production

Gold production for YTD 2026 totaled 198,142 ounces. Consistent with the Company's business plan for the year, quarterly production in 2026 is expected to be higher in the second half of the year than in the first six months, largely reflecting an increase in tonnes processed. The Company remains on track to achieve the 2026 production guidance of 260,000 – 300,000 ounces.

Unit Costs

Gold operating cash costs per ounce sold and gold AISC per ounce sold averaged $1,426 and $2,170, respectively, for YTD 2026, compared to full-year guidance of $1,250 – $1,400 and $1,950 – $2,250, respectively. The Company expects full-year 2026 gold operating cash costs per ounce sold and gold AISC per ounce sold to finish the year in line with the guidance ranges, with operating cash costs per ounce sold targeted to be at the top end of the range. Gold AISC of $2,170 excludes the $197 per ounce impact of share-based compensation.

Royalties

Royalty expense YTD 2026 totaled $19.8 million compared to full-year 2026 guidance of $25 – $35 million. Royalty expense is highly dependent on the average realized gold price and will fluctuate based on the commodity cycle. Royalty expense primarily relates to agreements with First Nations groups and private interests at Borden and, to a lesser extent, at Hoyle Pond and Pamour. The Company continues to target royalty expense of $25 – $35 million for full-year 2026.

Sustaining Capital Expenditures

Sustaining capital expenditures for 2026 are projected to be $120 – $165 million, with $94.8 million incurred YTD 2026. Expenditures during the year are primarily focused on work to buttress the TMA6 at the Dome property, as well as ongoing investment in capital improvements at the Dome Mill and new mobile equipment and improved infrastructure at Hoyle Pond and Borden. Capital development expenditures at Hoyle Pond and Borden during YTD 2026 were in line with expectations.

Porcupine Growth Capital Expenditures

Growth capital expenditures at Porcupine, excluding capitalized exploration expenditures, are targeted at $195 – $235 million. For YTD 2026, growth capital expenditures totaled $155.9 million, mainly related to investments at the TMA6 to increase tailings capacity through additional raises and to execute a new deposition strategy, continued pre-stripping at Pamour, as the mine ramps up towards commercial levels of operation, infrastructure work at Pamour and work to construct a camp at Borden. The Company expects full-year 2026 growth capital expenditures at Porcupine to be at the top end of the guidance range.

Cordero

The Company's initial guidance for fees and growth capital related to Cordero was $90 – $100 million, a significant component of which related to the anticipated payment of the Change of Land Use permit fee. During Q3 2026, the Company paid this fee, which totaled $11.6 million, an amount significantly lower than what had been assumed in the Company's initial 2026 guidance. Based on the fee paid, the Company has revised the 2026 guidance for Cordero fees and growth capital to $20 – $30 million. Total expenditures for YTD 2026 were $18.0 million, inclusive of the Change of Land Use fee.

Exploration

Total exploration expenditures in 2026, including both capitalized and expensed expenditures, are targeted at $55 – $75 million, with $43.7 million incurred as of September 30, 2026. The Company's exploration work program for the year involves an estimated 255,000 – 280,000 metres of drilling, as well as 1,200 – 1,400 metres of exploration development.

As of September 30, 2026, the exploration program had completed 205,680 metres of drilling and 429 metres of exploration development. A significant portion of the planned development in 2026 has related to an exploration drift to extend approximately 1.5 km from Hoyle Pond to Owl Creek. While initially expected to begin in Q3 2026, development of the drift is now targeted to commence during Q4 2026, with the majority of metres to be completed in 2027 and early 2028.

Capital exploration expenditures incurred for YTD 2026 totaled $20.8 million and are targeted at $25 – $35 million for the full year. Capital drilling during the quarter mainly related to ongoing resource conversion and expansion drilling at Hoyle Pond, Borden and Pamour.

Key targets include the S Zone Deep and XMS Zone at Hoyle Pond; the further northeast extension of the Main Zone and infill of the Far West and East Lower Zones at Borden; and within and along strike of all three phases of the Pamour pit design. Capitalized exploration expenditures also include planned drilling at Dome designed to upgrade and add confidence to current inferred resources located on the edges and below the historic Dome pit.

Expensed exploration expenditures in 2026 are targeted at $30 – $40 million, with total expenditures to the end of Q3 2026 of $22.9 million. Drilling in 2026 has focused on the mid-mine at Hoyle Pond, the TVZ Zone adjacent to Hoyle Pond, and Owl Creek, located three kilometres west along the Hoyle Pond volcanic belt. Other key targets for expensed exploration include the down plunge extension of the Main Zone at Borden, and several targets around Pamour, including the Pamour West area, North Contact and the Keora Trend.

As at November 9, 2026, the Company had 19 exploration drill rigs operating. A breakout of drill-rig locations and related targets is provided below:

Hoyle Pond: Five underground drills – One drill targeting each of the 1060 fault, the parallel 1060 target, the S Zone Upper ("SUPP") area, the VAZ lower target, and the North Mafic Vein West zone.

TVZ Zone: Three underground drills – One drill on the 900 level and one drill on the 1410 level, both primarily focused on infilling and extending mineralization proximal to historic drilling, and one drill on the 1680 level testing the down plunge extension of mineralization.

Owl Creek: One surface drill focusing on surface targets at Owl Creek and along the Hoyle Pond trend.

Borden: Three drills (two underground and one surface) – Two underground drills involved in infill and expansion drilling, mainly targeting the Main (Deep) Zone to the northeast, and one surface drill exploring to the northeast of the mine. Two additional drill rigs will be added underground at Borden in Q4 2026.

Pamour: Four surface drills – One drill focused on each of the following targets: The northeast Pamour open pit area, the area between the historic Pamour Pit and the historic Broulan Pit at Pamour West, the Keora Trend and the North Contact Zone.

Dome: Two surface drills located in the southwest portion of the historic open pit, with drilling continuing to evaluate additional drill targets to the north, south and west sides of the pit.

Kidd Area: One surface drill testing regional targets in the Kidd Creek area.

Corporate G&A

The Company's initial guidance for Corporate G&A in 2026 was $35 – $40 million. As of September 30, 2026, Corporate G&A costs totaled $40.4 million. Of this amount, $7.3 million related to the acquisition of the Kidd Operations and management changes, both of which were not anticipated in the Company's 2026 guidance. Corporate G&A levels in 2026 reflect Discovery's rapid transformation into a growing Canadian precious metals producer and the resulting requirement to strengthen organizational capabilities across operations, exploration, and corporate functions, such as finance and information technology. Based on the Company's current plans, and excluding the $7.3 million of expenses referenced above, Corporate G&A expense in 2026 is now targeted at $40 – $50 million.

NON-GAAP MEASURES

The Company has included certain non-GAAP measures in this document, as detailed below. In the mining industry, these are common performance measures and ratios but may not be comparable to similar measures or ratios presented by other issuers and the non-GAAP measures and ratios do not have any standardized meaning. Accordingly, these measures and ratios are included to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other issuers.

Free Cash Flow

Free Cash Flow is a non-GAAP performance measure that is calculated as cash flows from operations net of cash flows invested in mineral property, plant, and equipment and exploration and evaluation assets. The Company believes that this measure is useful to the external users in assessing the Company’s ability to generate cash flow after capital investments and build the cash resources of the Company.

Free cash flow is reconciled to the amounts included in the Consolidated Statements of Cash Flows as follows:

Operating Cash Costs, Operating Cash Costs per Ounce Sold, and Operating Cash Costs per Pound Sold

Operating cash costs, operating cash costs per ounce sold, and operating cash costs per pound sold are non-GAAP measures. In the gold mining industry, these metrics are common performance measures but do not have any standardized meaning under IFRS. Operating cash costs include mine site operating costs such as mining, processing, administration and royalty expenses but exclude depreciation and depletion and reclamation costs. Operating cash cost per ounce sold is based on ounces sold and is calculated by dividing operating cash costs by volume of gold ounces sold. Operating cash cost per pound sold is based on pounds sold and is calculated by dividing operating cash costs, net of by-product credits, by the volume of copper and zinc pounds sold. By-product credits are applied as a reduction to the operating cash costs of the metal from which the by-product is derived.

The Company discloses operating cash costs, operating cash costs per ounce sold, and operating cash costs per pound sold as it believes the measures provide valuable assistance to investors and analysts in evaluating the Company’s operational performance and ability to generate cash flow. The most directly comparable measure prepared in accordance with IFRS is production costs. Operating cash costs, operating cash costs per ounce sold, and operating cash costs per pound should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS.

Gold AISC and Gold AISC per Ounce Sold

Gold AISC and gold AISC per ounce sold are non-GAAP measures. These measures are intended to assist readers in evaluating the total costs of producing and selling gold from current operations. While there is no standardized meaning across the industry for this measure, the Company’s calculation is based on the definition of AISC as set out by the World Gold Council, except for share-based compensation. The World Gold Council is not a regulatory organization. It is a market development organization for the gold industry comprised of and funded by gold mining companies from around the world.

The Company defines gold AISC as the sum of operating costs (as defined and calculated above), sustaining capital, exploration expense, corporate expenses, lease payments relating to sustaining assets, and reclamation cost accretion and depreciation related to current operations. Corporate expenses include general and administrative expenses, net of transaction related costs and severance expenses for management changes. Gold AISC excludes growth capital expenditures, growth exploration expenditures, reclamation cost accretion and depreciation not related to current operations, lease payments related to non-sustaining assets, interest expense, debt repayment, taxes and share-based compensation.

Operating cash costs and Gold AISC Reconciliation

The following tables reconcile these non-GAAP measures to the most directly comparable IFRS measures available for Q3 2026, Q2 2026, Q3 2025, YTD 2026 and YTD 2025:

Average Realized Price per Ounce Sold

In the gold mining industry, average realized price per ounce sold is a common performance measure that does not have any standardized meaning. The most directly comparable measure prepared in accordance with IFRS is revenue from gold sales. Average realized price per ounce sold should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS. The measure is intended to assist readers in evaluating the total revenues realized in a period from current operations.

Adjusted Net Earnings and Adjusted Net Earnings per Share

Adjusted net earnings and adjusted net earnings per share are used by management and investors to measure the underlying operating performance of the Company. Adjusted net earnings is defined as net earnings adjusted to exclude the after-tax impact of specific items that are significant, but not reflective of the underlying operations of the Company, including foreign exchange gains and losses and other non-recurring items. Adjusted net earnings per share is calculated using the weighted average number of shares outstanding.

Working Capital

Working capital is a non-GAAP measure. In the gold mining industry, working capital is a common measure of liquidity, but does not have any standardized meaning. The most directly comparable measures prepared in accordance with IFRS are current assets and current liabilities. Working capital is calculated by deducting current liabilities from current assets. Working capital should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS. The measure is intended to assist readers in evaluating the Company’s liquidity. Working capital is reconciled to the amounts in the Consolidated Statements of Financial Position as follows:
