•

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 fillthe-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 drilltested, 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.
