Wesdome Reports Strong Second Quarter 2026 Results and Reaffirms Full-Year Production and Cost Guidance

Toronto, Ontario--(Newsfile Corp. - August 13, 2026) - Wesdome Gold Mines Ltd. (TSX: WDO) (OTCQX: WDOFF) ("Wesdome" or the "Company") today announced its financial results for the three and six months ended June 30, 2026 ("Q2 2026" and "H1 2026"). Preliminary operating results for Q2 2026 were disclosed in the Company's press release dated July 13, 2026. Management will host a webcast tomorrow morning, August 14, 2026 at 10:00 a.m. ET to discuss its results. All amounts are expressed in Canadian dollars unless otherwise indicated.

Q2 2026 Highlights

• Strong safety performance: High Potential Incident Frequency Rate declined 69% year-over-year to 0.67, reflecting the strong commitment to safety across the organization. Total Recordable Incident Frequency Rate of 1.67 in Q2 2026.

• Production and costs: Consolidated gold production for the second quarter was 43,824 ounces, a 2% increase compared to Q2 2025. Q2 2026 cash costs per ounce of gold sold¹ increased by 45% to US$1,342 and all-in sustaining costs ("AISC") per ounce of gold sold¹ increased by 15% to US$1,763 compared to Q2 2025.

• Revenue growth: Consolidated Q2 2026 revenue increased by 28% to $267 million compared to Q2 2025. The average realized price of gold sold was US$4,365 per ounce in Q2 2026.

• Expanding margins: Gross profit increased by 22% year-over-year in Q2 2026 to $161 million and operating cash margin¹ grew by 23% to $184 million.

• Net income: Q2 2026 net income of $94 million, or $0.64 earnings per share, an increase of $11.3 million compared to Q2 2025.

• EBITDA¹: EBITDA¹ was $170 million in Q2 2026, a 23% increase relative to Q2 2025.

• Cash flow¹: Q2 2026 net cash from operating activities was $88 million, or $0.59 per share³, with free cash flow¹ of $42 million, or $0.28 per share. Free cash flow¹ decreased to $42 million, or $0.28 per share, from $53 million, or $0.35 per share, in Q2 2025 driven by higher net income offset by a combined increase in tax payments, receivables, supplies inventories, mine exploration and development and capital equipment purchases.

• Strong liquidity position: As at June 30, 2026, the Company had liquidity of $746 million, including $391 million in cash and US$250 million of undrawn full capacity available under its revolving credit facility.

• Expanded capital returns:The Company is delivering capital returns to shareholders while preserving flexibility to act opportunistically, within a framework that continues to prioritize fully funded organic growth:

  • Share buyback expansion: Through Q2 2026, the Company purchased and cancelled 3.2 million common shares for approximately $82 million at an average price of $25.66 per share. On June 24, 2026, the Company announced it was expanding its normal course issuer bid, authorizing the purchase of an incremental 3.0 million shares, bringing the total aggregate number of shares the Company intends to repurchase up to approximately 9.0 million shares or 6% of its public float. In July 2026, the Company repurchased an additional 1.8 million shares for approximately $46 million. The total number of shares purchased at the end of July was 7.8 million shares.

• Updated technical reports confirm extended mine lives and growth potential at Eagle River and Kiena:Filed independent NI 43-101 technical reports for Eagle River and Kiena, confirming 1.4 million ounces of consolidated proven and probable reserves and 8-year reserve-based mine plans through 2033 at both operations, with significant organic growth potential from resource conversion and exploration targets.

• Kiena ramp breakthrough achieved, enhancing operational flexibility:Kiena's new ramp reached surface in Q2 2026, establishing continuous ramp access that boosts underground materials and equipment flexibility and enables the ongoing ventilation expansion project, expected to double mine ventilation capacity to support production growth at Kiena.

• Discovery in Kiena Deep, Norbenite Footwall: As reported in the Company's press release dated June 22, 2026, drilling in Kiena Deep discovered a new parallel zone beyond the Norbenite Fault, previously interpreted as barren footwall, highlighted by 6.9 g/t over 42.1 metres, confirming an entirely new mineralized corridor, called the Norbenite Footwall, spanning at least 150 vertical metres. This discovery represents a significant new exploration opportunity for future resource growth at Kiena.

Anthea Bath, President and Chief Executive Officer, commented: "Q2 2026 demonstrated the operational momentum we have been building across both assets, giving us the confidence to reaffirm our full year production and cost guidance.

"At Eagle River, the integration of global model ore into our fill-the-mill strategy is now a structural part of how we run the mine. This approach is driving higher mill throughput and, as we move through the second half of the year, we expect grade improvement, keeping Eagle River firmly on track to deliver its full year production and cost targets.

"Kiena's performance this quarter was a genuine inflection point. Production increased 28% year over year with unit costs in line with plan. In July we brought the first Presqu'île stope online, successfully adding another mining front beyond Kiena Deep. Operating across multiple areas of the mine provides greater flexibility and reduces grade variability, while ongoing operational improvements and optimization initiatives support a steady ramp-up in production over time.

"Overall, it was a strong quarter with higher margins and robust EBITDA. Free cash flow was negatively impacted by several items, most notably the timing of a $21 million prepaid tax installment. Based on our current forecasts, we expect quarterly free cash flow to increase significantly over the balance of the year.

"Perhaps most importantly for investors, there is greater visibility into Wesdome's long-term value proposition. Our June technical report update established eight-year reserve mine lives at both mines, providing a foundation for production and cash flow while preserving significant upside from operational optimization, resource conversion and exploration. Together with our strong balance sheet, we have the flexibility to invest in organic growth while also returning capital through our quarterly dividend and expanded share buyback program. We have two long-life assets, a clear pathway to grow production, and emerging district-scale opportunities around both operations. Our focus now is on converting that potential into sustainable growth and increasing value per share."

Operating Highlights

Eagle River gold production decreased by 15% to 21,798 ounces in Q2 2026 from 25,612 ounces in Q2 2025. The decrease was in line with the Company's plan in Q2 2026 and reflects the blending of Global Model ore as part of Eagle River's fill-the-mill strategy, which increased tonnes processed by 49%, partly offset by a 43% decrease in average grade. The lower average grade reflects the addition of economic ounces and tonnes from the Global Model and mine plan sequence in the quarter, which are additive to ounces from Eagle River's high-grade ore.

Eagle River produced 49,644 ounces in the first half of 2026, a decrease of 9% compared to 54,611 ounces in the first half of 2025. In the beginning of the first half of 2026, Eagle River commenced processing Global Model ore as part of its fill-the-mill strategy, which drove a 33% increase in tonnes processed while reducing average grade by 43% in H1 2026 compared to H1 2025. In the second half of 2026, Eagle River will continue to incorporate Global Model ore into the mine plan sequence, resulting in increased mill throughput, expecting average grades to improve relative to Q2 2026. Eagle River is on track to achieve its full-year production guidance for 2026.

Mill throughput of 72,439 tonnes in Q2 2026 was 49% higher than the second quarter of 2025 reflecting higher ore and mill availability. Mill throughput of 144,170 tonnes during the first half of 2026 was 33% higher when compared to the same period in 2025 as the initiatives to continue to improve mine and mill productivity are yielding more consistent tonnage delivery to leverage the capacity of the mill complex.

Driven by a 49% increase in tonnes processed in Q2 2026, production costs increased slightly to $631 per tonne from $626 per tonne in Q2 2025, despite inflationary pressure on wages, supplies, fuel and insurance that have been broadly felt across the industry. Q2 2026 costs also included one-time costs which impacted cost per tonne by $45, whereas Q2 2025 benefited from higher inventory levels, reducing the cost per tonne by $95. Production costs per tonne in the first six months of 2026 increased by 2% to $609 per tonne compared to $598 per tonne in the first six months of 2025, reflecting similar factors. Production costs are expected to start declining in the second half of the year as several cost items incurred in Q2 2026 are not expected to recur and the cost benefits of the fill-the-mill strategy become more apparent as mill throughput continues to increase and existing fixed costs are better leveraged.

Financial Highlights

In Q2 2026, Eagle River's gold revenue increased by 9% to $133.5 million from $122.6 million in Q2 2025 due to the higher average realized price of gold sold, offset by a 17% decrease in ounces sold. During the first half of 2026, Eagle River's gold revenue increased by 31% to $312.2 million from $238.0 million in the same period in 2025 due to the 49% increase in the average realized price of gold sold, partly offset by a 9% decrease in ounces sold.

Cost of sales in Q2 2026 was $49.6 million, an increase of 52% relative to the comparative period in 2025 primarily due to a $5.7 million increase in mine and mill operating costs due to one-time costs, inflationary impacts, contractors and maintenance costs, costs associated with increased royalties mainly due to higher average gold price, and a change in inventory levels of $4.9 million.

Cost of sales for the first half of 2026 totaled $95.3 million, a 37% increase compared to the same period in 2025. This was principally driven by a $7.1 million increase in mine and mill operating costs due to similar factors described above and increased royalties from higher gold prices, further elevated by a $8.8 million change in inventory levels.

Cash costs per ounce of gold sold increased by 84% to $2,218 (US$1,603) per ounce sold in Q2 2026 from $1,207 (US$872) per ounce sold in Q2 2025 due to a 17% decrease in ounces sold and a 6% increase in throughput costs due to one-time costs, inflationary impacts, contractors and maintenance costs. Similarly, cash costs per ounce of gold sold increased by 51% to $1,911 (US$1,386) per ounce sold in the first half of 2026 from $1,268 (US$899) per ounce sold in the comparative period in 2025 due to increased cost of sales and a 9% decrease in ounces sold.

In Q2 2026, AISC per ounce of gold sold increased by 45% to $2,800 (US$2,023) from $1,929 (US$1,394) in Q2 2025, due to the increase in cash costs per ounce sold partially offset by a 31% reduction in sustaining capital expenditures due to timing and a 17% decrease in ounces sold.

During the first half of 2026, AISC per ounce of gold sold increased by 28% to $2,471 (US$1,794) per ounce sold from $1,924 (US$1,365) per ounce sold in the same period in 2025, due to higher cash cost per ounce sold partially offset by a 25% reduction in sustaining capital expenditures due to timing and a 9% decrease in ounces sold. In H2 2026, the rate of capital expenditures is expected to increase as Eagle River accelerates deferred development and capital projects including the installation of a new camp and tailings management area construction. Higher ounce production is expected to offset higher sustaining capex and result in lower AISC per ounce sold in the second half of the year. Based on the current forecast for the balance of the year, Eagle River's AISC per ounce sold is expected to fall within its full-year guidance range of $1,525 - $1,675 per ounce sold.

Exploration Update

Expanding the 6 Central Zone

The 6 Central Zone is considered a priority exploration area given its intermediate depth, proximity to existing mine infrastructure and geological similarities to the 300 Zone at comparable elevations. The zone remains underdrilled and open down plunge and laterally. The 2026 program is designed to further define the geometry and continuity of the high-grade mineralization and test its down-plunge extension, with approximately 9,600 metres planned for the year. Recent results continue to support the interpretation that the high-grade trend extends at depth, and drilling will continue in the second half of the year. Continued success could support future resource growth and provide an additional source of high-grade ore at depths shallower than those currently being mined in the 300 Zone.

Growing the 800 Zone

Growth drilling continued during the quarter. Shears with quartz veining were logged in holes in-filling a gap in drilling that coincided with potential up-plunge continuation of mineralization. The logging observations support the structural and geologic continuation of the zone, with assays pending. Holes designed to test the down-plunge continuation were deferred until later in the year. The 2026 exploration program is targeting to drill approximately 10,000 metres in the 800 Zone.

Growth Drilling in 700 Zone

Growth drilling evaluating the continuation of mineralization in the shallow parts of the mine, 350 Level, returned assays with thickness and grades confirming continuation of the mineralization. Infill drilling as part of conversion continues into the next quarter. Assays from drilling program are pending.

Global Model

The Global Model is a dynamic exploration framework that is continuously updated as new geological, drilling and other technical information becomes available. New prospective areas are added for both conversion and growth as the geological understanding of the Eagle River system evolves, while areas that have been sufficiently drill-tested, or are no longer considered priorities based on technical or geology considerations, are reprioritized.

The contribution of Global Model areas to the 2025 Mineral Reserve additions demonstrates how this systematic process can progressively convert previously unrecognized or underutilized areas of the Eagle River mineralized system into mineable inventory.

Global Model targets are integrated into Eagle River's ongoing underground drilling programs, with typically two to three of the mine's four underground exploration drill rigs testing these areas. During the quarter, drilling continued across several Global Model targets, including conversion drilling of Global Model Target 19 in the deeper portions of the 300 Zone. Results continue to refine the geological interpretation and identify opportunities for resource growth and conversion.

Surface Exploration

Surface holes tested an area of mineralization to the east of No Name Lake (NNL), where historic widely spaced drill holes intersected mineralization. The surface holes were designed to infill and confirm continuation of NNL mineralization. Results will be reported in the last quarter.

At North Diorite, a gradient array IP geophysical survey was completed, aimed at mapping out continuation of quartz veins and sulphide rich horizons highlighted by previous work. Survey results are expected in the third quarter.

At Dorset Main, Dorset West, and Cameron Iron Formation, drilling for geometallurgical sampling for leach and recovery test work, and deportment studies, continued as part of overall deposit resource evaluation.

Helicopter-supported scout drilling was completed at Magnacon East, evaluating the sub-surface potential of quartz veins that returned high-grade assays from rock chip samples collected during semi-regional structural mapping program executed in 2025. The area is located approximately 3 km east of the historic Magnacon mine.

Helicopter-supported scout drilling was also completed at Feather River, located approximately 8km east of Magnacon mine. The holes were designed to evaluate the continuation of quartz veins and sulphide rich horizons highlighted by previous work which included geologic mapping, local IP surveys, and scout drilling which returned anomalous intercepts.

Surface drilling continued at Mishi open pit, evaluating the down-plunge potential of mineralization, and expanding the continuation of near surface mineralization as part of overall resource evaluation. Results are expected to be reported in Q4.

Final products of AI prospectivity mapping were also received during the quarter. ALS Canada Ltd. leveraged data analytics, machine learning and numeric modelling to reprocess and level Eagle River's geophysical, geologic and geochemical data and incorporate the information into their AI related workflow. The prospectivity work has highlighted five new areas that have not been previously considered by the team, further expanding the pipeline of regional exploration opportunities (see Figure 1 below).

Existing high priority work areas represent a combination of high grade (Entirety of Eagle River Deformation Zone, Eagle River Splay/North Diorite) and bulk tonnage lower grade opportunities (Mishibishu – East and West of mines, Dorset East and West, and Central block of Cameron Lake Iron Formation). The prospectivity mapping has flagged an observation that the far east Eagle River Deformation Zone is of similar size to the Eagle River Mine area, and as such warrants priority focus.

The five new prospectivity areas of interest include Feather River South – hosting two areas with minimal surface work and understanding; Mishi West - at the convergence of Iron Lake Deformation Zone; North of Mishi – in a strain shadow of intrusion and possible second thrust zone similar to the Mishibishu Deformation Zone; Rook Lake West – in strain shadow west of Mishibishu Lake Intrusion, where Dorset Deformation Zone may be trending; Southeast portion of Cameron Lake Iron Formation – a complex area with favorable host lithologies and structure. Follow-up field programs to advance the existing high priority work areas, and the five new prospectivity areas of interest will be designed, ranked and scheduled during workshops planned for the third quarter, with the results incorporated into the Company's broader exploration targeting and prioritization process.

Operating Highlights

In Q2 2026, Kiena produced 22,026 ounces, a 28% increase from 17,169 ounces in Q2 2025. Production levels reflect a 24% increase in throughput reflecting additional tonnage production from Presqu'île and a 3% increase in average grade from higher grades at Kiena Deep. The ramp-up remains on track through the second half of 2026, with the first stope on the 136 Level completed in Q2 and the first Presqu'île stope initiated in July 2026 providing access to three simultaneous mining horizons in H2 2026.

Production in the first half of 2026 totaled 39,483 ounces compared to 33,862 ounces in the first half of 2025 reflecting the addition of Presqu'île ounces and beginning to see improvements to stability from the operating model implementation and the addition of a new mining horizon providing additional mine sequence flexibility at Kiena Deep.

Average grade for the quarter was 11.14 g/t, up from 10.8 g/t in Q2 2025, driven by planned higher grades in Kiena Deep. With the operational flexibility provided by mining two zones in Kiena Deep and the addition of the near surface Presqu'île Zone, as well as the completion of ramp access, full-year 2026 production and grade guidance remain on track.

Production costs per tonne were $526 in Q2 2026, the same as in Q2 2025, despite higher maintenance and contractor costs, offset by higher tonnage throughput. Production costs per tonne increased to $554 in the first half of 2026 from $501 in the comparative prior year period, primarily driven by higher maintenance and contractor costs, partially offset by higher tonnage throughput.

Financial Highlights

In Q2 2026, Kiena's gold revenue increased by 55% to $132.8 million from $85.8 million in Q2 2025, primarily due to a higher average realized price per ounce of gold sold and a 15% increase in ounces of gold sold. In the first half of 2026, Kiena's gold revenue increased by 61% to $253.4 million from $157.7 million in the comparative period in 2025, due to the higher average realized price of gold and a 10% increase in ounces sold.

Cost of sales in Q2 2026 was $32.7 million, an increase of 24% over the comparative period in 2025 primarily due to a $5.5 million increase in mine operating costs including higher maintenance and contractor costs, and inflationary pressures. Cost of sales in the first half of 2026 was $64.9 million, an increase of 31% over the comparative period in 2025 primarily due to a $12 million increase resulting from similar factors.

Cash costs per ounce of gold sold in Q2 2026 were $1,489 (US$1,076), an increase of 7% compared to $1,397 (US$1,009) in Q2 2025 primarily due to similar factors noted in cost of sales. Cash costs per ounce of gold sold in the first half of 2026 were $1,607 (US$1,166), an increase of 19% compared to $1,354 (US$961) in the comparative period in 2025 primarily due to higher mine unit operating costs impacted by higher maintenance and contractor costs.

AISC per ounce of gold sold decreased by 13% in Q2 2026 to $2,071 (US$1,497) from $2,380 (US$1,720) in Q2 2025 due to a 45% decrease in sustaining capital expenditures due to timing and higher ounces sold. AISC per ounce of gold sold increased by 3% in the first half of 2026 to $2,271 (US$1,649) from $2,209 (US$1,567) in the first half of 2025 due to an increase in aggregate mine operating costs primarily due to contractor and maintenance costs, partially offset by a 10% increase in ounces sold and a decrease in sustaining capital expenditures due to timing. While sustaining capital is anticipated to increase in H2 with additional development and key projects executed and planned production ramp up in the second half of 2026, guidance for 2026 is on track for the year.

Progress at Presqu'île Zone

Development at the Presqu'île Zone progressed as anticipated, and the first stope was blasted mid-July. Stoping and production ramp-up will continue to ramp up through the second half of 2026.

Ramp Breakthrough

Kiena achieved a major milestone in Q2 2026 with the breakthrough of the new ramp to surface, establishing continuous ramp access and significantly increasing flexibility for underground material and equipment movement. Completion of the ramp also enables the ongoing ventilation expansion project, which is expected to double mine ventilation capacity and support increased mining activity and future productivity improvements.

Exploration Update

134 Level

The Norbenite Footwall discovery announced in June continues to build excitement. The reported drill results were exceptional in the two holes which were over 150m apart vertically. Drilling from the 134-level exploration drift continued to evaluate the Norbenite Footwall mineralized zone, with holes in-filling the 150m gap. The new holes intersected geology with similar thickness, veining and localized observations of VG as the previously reported holes, growing confidence in the continuity of the mineralized zone. An exploration update with the results of the drilling is scheduled for quarter three.

Drilling from the 134-level ramp continued to confirm the continuity of the Kiena Deep A and Kiena Deep Footwall zones, with two rigs expected to continue drilling from these platforms over the next two quarters. The results will contribute towards resource growth.

109-Level Exploration Drift

Exploration drilling from the 109-level continued to advance the VC Zone and evaluate the broader mineralized potential of this area. The VC Zone remains open at depth and exhibits a style of mineralization analogous to Kiena Deep, supporting continued exploration of the system. Importantly, drilling from the 109-level has also intersected basalt-hosted mineralization within approximately 100 metres of the drill bay that is being interpreted as a potentially new mineralized zone, distinct from the VC Zone. Follow-up drilling is underway to evaluate the geometry and continuity of this basaltic lens within the surrounding ultramafic sequence.

On 33-Level, exploration drilling tested the northwest continuation of the Shawkey Main zone toward the Wish deposit. Quartz veining was intersected at the targeted depths and assays are pending. Drilling in this area is planned to continue over the next two quarters. A separate hole testing a magnetic-low target south of Dubuisson returned low values.

Surface Exploration

Barge drilling commenced later in the second quarter with one rig at Dubuisson, evaluating the continuation of intrusive unit and mineralization at depth, and a second rig at Tarmac near the historic Siscoe mine and a third rig drilling the Northwest Zone. A fourth rig is scheduled to commence at Wesdome early in the third quarter.

Drilling with a land-based rig has also commenced at Shawkey South/Shawkey 10, evaluating the bulk tonnage style of mineralization at depth.

OUTLOOK

2026 Consolidated Guidance Commentary

The information below reflects the Company's current forecast for the full year.

• Consolidated Gold Production: 180,000 to 205,000 ounces (midpoint 192,500 ounces)

  • The Company remains on track to meet its full-year gold production guidance of 180,000 to 205,000 ounces (midpoint 192,500 ounces), with H1 production of 89,127 ounces representing 46% of the midpoint.

  • Eagle River is expected to achieve its full-year production guidance range of 105,000 to 115,000 ounces at a lower average grade of 11.5-12.5 g/t compared to initial guidance range of 13.0-14.0 g/t. In H2 2026, the continued integration of Global Model ore into the mine plan will drive higher mill throughput and improved grades compared to H1 2026.

  • Kiena is expected to achieve its 75,000-to-90,000-ounce guidance at an average grade of 8.0-9.5 g/t, broadly in line with reserve grades. Nearly 60% of output is weighted to H2 2026, reflecting improved operational stability at Kiena Deep and incremental contributions from Presqu'île.

• Depreciation and Depletion: $100 million (previously $130 million)

  • Based on the updated Technical Reports and the mineral reserves published on June 24, 2026, the Company is lowering its guidance for depreciation and depletion from $130 million to $100 million.

• Cash Costs Per Ounce Sold: US$1,050 to US$1,150 (midpoint: US$1,100)

  • Consolidated cash costs per ounce of gold sold are expected to fall within the 2026 guidance range of US$1,050 to US$1,150.

  • As outlined in its original guidance (see the Company's release dated January 20, 2026), Eagle River's cash costs per ounce sold are expected to increase in 2026 over the prior year, primarily reflecting higher royalties from higher revenue.

  • Kiena's cash costs per ounce sold are expected to be at the upper end of guidance due to higher input costs, primarily labour and contractors.

• All-in Sustaining Costs Per Ounce Sold: US$1,525 to US$1,700 (midpoint: US$1,612)

  • Consolidated all-in sustaining costs per ounce of gold sold are expected to fall within the initial 2026 guidance range of US$1,525 to US$1,700.

  • Eagle River's Q2 2026 AISC of US$2,023 per ounce sold was higher than its guidance range of US$1,525 to US$1,675 per ounce sold. However, Eagle River is anticipated to achieve full-year guidance as higher grade in H2 2026 is expected to offset higher sustaining capex and result in lower AISC per ounce sold in the second half of the year.

  • Kiena remains on track to achieve its annual AISC guidance of US$1,525 to US$1,750 per ounce sold.

• Total Capital Investments: $205 million

  • Based on our most recent forecast, full-year consolidated capital spend could track up to 10% higher than initial guidance of $205 million, primarily driven by the timing of growth expenditures.

The following table outlines Wesdome's updated 2026 guidance compared to its initial guidance set forth in the Company's press release dated January 20, 2026:

1. Consolidated guidance for 2026 corporate and general costs excludes an estimated $9 million in stock-based compensation. Corporate general and administrative costs of $30 million is allocated equally to each mine and is included in the Company's calculation of all-in sustaining costs.
2. Exploration and evaluation costs primarily include surface drilling activities and regional office expenses and are not included in all-in sustaining costs.

Non-IFRS Performance Measures

Wesdome uses non-IFRS performance measures throughout this MD&A as it believes that these generally accepted industry performance measures provide a useful indication of the Company's operational performance. These non-IFRS performance measures do not have standardized meanings defined by IFRS and may not be comparable to information in other gold producers' reports and filings. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

The non-IFRS performance measures include:

• Average realized price per ounce of gold sold

• Cash costs and cash costs per ounce of gold sold

• Production costs per tonne milled

• Operating cash margin and operating cash margin per ounce of gold sold

• Sustaining capital and growth capital

• AlSC and AISC per ounce of gold sold

• Free cash flow and free cash flow per share

• Adjusted net income and adjusted net earnings per share

• EBITDA

Average Realized Price per Ounce of Gold Sold

Average realized price per ounce of gold sold is a non-IFRS measure and does not constitute a measure recognized by IFRS and does not have a standardized meaning defined by IFRS. Average realized price per ounce of gold sold is calculated by dividing gold revenue from the Company's mining operations for the relevant period by the ounces of gold sold. It may not be comparable to information in other gold producers' reports and filings.

Cash Costs and Cash Costs per Ounce of Gold Sold

Cash costs per ounce of gold sold is a non-IFRS performance measure and does not constitute a measure recognized by IFRS and does not have a standardized meaning defined by IFRS, as well it may not be comparable to information in other gold producers' reports and filings. The Company has included this non-IFRS performance measure throughout this document as it believes that this generally accepted industry performance measure provides a useful indication of the Company's operational performance. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company's operating performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The following table provides a reconciliation of total cash costs per ounce of gold sold to cost of sales per the financial statements:

Production Costs and Production Costs per Tonne Milled

Production costs per tonne milled is a non-IFRS performance measure and does not constitute a measure recognized by IFRS and does not have a standardized meaning defined by IFRS, and as well it may not be comparable to information in other gold producers' reports and filings. As illustrated in the table below, this measure is calculated by adjusting cost of sales, as shown in the statements of income for non-cash depletion and depreciation, royalties and inventory level changes and then dividing by tonnes processed through the mill. Management believes that production costs per tonne milled provides additional information regarding the performance of mining and milling operations and allows management to monitor operating costs on a more consistent basis as the per tonne milled measure reduces the cost variability associated with varying production levels. Management also uses this measure to determine the economic viability of mining blocks. As each mining block is evaluated based on the net realizable value of each tonne milled, the estimated revenue on a per tonne basis must be in excess of the production costs per tonne milled in order to be economically viable. Management is aware that this per tonne milled measure is impacted by fluctuations in throughput and thus uses this evaluation tool in conjunction with cost of sales prepared in accordance with IFRS. This measure supplements cost of sales information prepared in accordance with IFRS and allows investors to distinguish between changes in cost of sales resulting from changes in production versus changes in operating performance.

Operating Cash Margin and Operating Cash Margin per Ounce of Gold Sold

Operating cash margin is a non-IFRS measure and does not constitute a measure recognized by IFRS and does not have a standardized meaning defined by IFRS, and as well it may not be comparable to information in other gold producers' reports and filings. It is calculated as the difference between gold revenue from mining operations and cash mine site operating costs (see cash costs per ounce of gold sold section above) per the Company's financial statements. The Company believes operating cash margin illustrates the performance of the Company's operating mines and enables investors to better understand the Company's performance in comparison to other gold producers who present results on a similar basis.

Sustaining Capital and Growth Capital

Sustaining capital expenditures are generally defined as expenditures that support the ongoing operation of the asset or business without any associated increase in capacity, life of assets or future earnings. This measure is being used by management to understand the ongoing capital cost required to maintain operations at current levels. In Q2 2026, there was a reclass adjustment related to Eagle River exploration activities.

Growth capital expenditures are generally defined as capital expenditures that expand existing capacity, increase life of assets and/or increase future earnings. This measure is used by management to understand the costs of developing new operations or major projects at existing operations where these projects will materially increase production from current levels.

AISC and AISC per Ounce of Gold Sold

AISC includes mine site operating costs incurred at the Company's mining operations, sustaining mine capital and development expenditures, mine site exploration and evaluation expenditures and equipment lease payments related to the mine operations and corporate and general expenses. The Company believes that this measure represents the total cash costs of producing gold from current operations and provides the Company and other stakeholders with additional information that illustrates its operational performance and ability to generate cash flow. This cost measure seeks to reflect the total cost of gold production from current operations on a per ounce of gold sold basis. New project and growth capital are not included. Wesdome is targeting to begin calculating AISC in accordance with the World Gold Council guidelines starting in the 2027 calendar year in conjunction with IFRS 18 reporting changes, ensuring alignment with industry standards and improved comparability for investors.

Free Cash Flow and Free Cash Flow per Share

Free cash flow is a non-IFRS measure and is calculated by taking net cash provided by operating activities less cash used in capital expenditures and lease payments as reported in the Company's financial statements. Free cash flow is a useful indicator of the Company's ability to operate without reliance on additional borrowing or usage of existing cash. Free cash flow per share is calculated by dividing free cash flow by the weighted average number of shares outstanding for the period.

Adjusted Net Income and Adjusted Net Earnings per Share

Adjusted net income and adjusted net earnings per share are non-IFRS performance measures and do not constitute a measure recognized by IFRS and do not have standardized meanings defined by IFRS, and as well both measures may not be comparable to information in other gold producers' reports and filings. Adjusted net income is calculated by removing the one-time gains and losses resulting from the disposition of non-core assets, non-recurring expenses and significant tax adjustments (mining tax recognition and exploration credit refunds) not related to the current period's income, as detailed in the table below. The Company discloses this measure, which is based on its financial statements, to assist in the understanding of the Company's operating results and financial position.
