• Record EBITDA1: EBITDA1 was a record $195 million in Q4 2025, a 70% increase relative to Q4 2024 and

was $602 million during 2025, a 96% increase relative to 2024.

• Record net cash from operating activities and free cash flow 1: Q4 2025 n et cash from operating

activities was $156 million, or $1.04 per share3, while free cash flow1 was $97 million, or $0.65 per share in

the fourth quarter. For 2025, net cash from operating activities was $457 million, or $3.04 per share3, while

free cash flow1 was $278 million, or $1.85 per share.

• Record liquidity: As at December 31, 2025, liquidity stood at $ 697 million, including $354 million in cash

and US$250 million of undrawn full capacity available under its revolving credit facility, compared to liquidity

of $273 million (including $123 million in cash) as at December 31, 2024.

• Normal course issuer bid: In the fourth quarter, the Company purchased and cancelled 706,100 common

shares for approximately $14 million at an average price of $20.37 per share.

Anthea Bath, President and Chief Executive Officer, commented: "2025 was a record year for Wesdome, as strong

gold prices combined with continued improvements in operational execution. Both operations met their restated

guidance, resulting in robust financial performance and a strong balance sheet while continuing to progress

2

operational initiatives aimed at improving consistency and cost efficiency. During the year, our free cash flow margin

expanded to 31%, enabling continued investment in the long-term potential of the business while increasing balance

sheet strength, acquiring Angus Gold, initiating a return of capital to shareholders through a share buyback program

and maintaining financial flexibility to support future opportunities.

“At the site level, Eagle River made meaningful progress toward fully utilizing mill capacity during the year, achieving

average daily mill throughput of 70% of permitted capacity, a material improvement over 2024. All-in sustaining

costs per ounce in the fourth quarter at Eagle River were the highest of the year due to higher tonnes milled at lower

grade as we opportunistically extended development into a lower-grade area of the 300 Zone that was not included

in our existing resources.

“At Kiena, the team focused on enhancing operational flexibility through the development of two new mining

horizons and the advancement of two new exploration drifts designed to optimize drilling eff ectiveness. Kiena

remains focused on strengthening operational stability with initiatives underway to improve mining sequence

execution and cost performance and is expected to deliver more consistent results starting in the second half of

2026. All-in sustaining costs per ounce at Kiena increased in the fourth quarter relative to 2024 primarily due to

higher sustaining capital expenditures, resulting from timing of equipment deliveries.

“2026 is expected to be a pivotal year for exploration at our operations. We plan to release results from our 270,000-

metre exploration program at regular intervals throughout the year, providing ongoing insight into the potential

across our portfolio. In June, we also expect to publish updated technical report summaries on both assets , which

we believe will give the market greater visibility into the longevity of our assets. Together, these milestones should

further demonstrate the long-term growth potential in our asset base."

Operating Highlights

During Q4 2025, Eagle River produced 23,861 ounces of gold as compared to 26,702 ounces in Q4 2024 as a

result of lower-grade development ore which was opportunistically incorporated into the plan to open up additional

future stopes, partially offset by a drawdown from the higher -grade surface stockpile. As a result, these additional

stopes will be included in the 2026 plan, along with the carryover of the original planned stopes from Q4 2025.

For 2025, Eagle River produced 112,768 ounces, a 19% increase over the 94,561 ounces produced in 2024. The

increase relative to the prior year reflects a 3% increase in average grade and a 16% increase in mill throughput .

The increase in mill throughput and mine productivity is largely driven by the optionality created with the expansion

and addition of new mining zones year over year, facilitating elevated levels of operational performance. In addition,

continuous improvement initiatives are resulting in m eaningful reductions in dilution and positive reconciliation on

specific stoping blocks in the 300 Zone. These results in the year demonstrate continued advancements made in

optimizing stope design, improving execution, and refining grade control.

6

Mill throughput of 77,240 tonnes in Q4 2025 was 28% higher than the fourth quarter of 2024 benefiting from

replacement of trunnion gear mid-year. For the year, mill throughput of 257,448 tonnes during 2025 was 16% higher

when compared to the prior year 2024, as a result of a debottleneck study, improved reliability through maintenance

practices, and specific mechanical replacements such as the trunnion gear mid-year

Q4 2025 production costs of $55 7 per tonne were 10% higher than the fourth quarter of 2024, primarily due to a

higher ratio of ore development to stope production, and an increased reliance on contractors to address vacancies

in operations personnel. For 2025, production costs per tonne of $560 per tonne were comparable to 2024.

Financial Highlights

In Q4 2025, Eagle River’s gold revenue increased 48% to $152.5 million from $103.4 million in Q4 2024 due to a

higher average realized price of gold sold, partially off set by a 5% reduction in ounces sold. During 2025, Eagle

River’s gold revenue increased by 77% to $549.0 million when compared to the previous year due to a higher

average realized price of gold sold and a 21% increase in ounces sold.

Cost of sales in Q4 2025 were $46.0 million, an increase of 34% relative to the comparative period in 2024 primarily

due to a $6.6 million increase in mine and mill operating costs due to higher tonnes processed, a $4.2 million change

in inventory levels and increased royalties mainly due to more tonnes processed. Cost of sales for 2025 totaled

$154.2 million, a 20% increase compared to the prior year. This was principally driven by a $21.4 million increase

in mine and mill operating costs, reflecting highe r throughput and increased royalties from increased gold

production.

Q4 2025 cash costs per ounce of gold sold increased to $1,745 (US$1,251) per ounce sold from $1,245 (US$890)

per ounce sold in Q4 2024 primarily due to fewer ounces sold in Q4 2025. Full year cash costs per ounce of gold

sold decreased to $1,3 51 (US$967) per ounce sold in 2025 from $ 1,370 (US$1,000) per ounce sold in the prior

year primarily due to higher ounces sold in 2025.

In Q4 2025, AISC per ounce of gold sold increased by 27% to $2,687 (US$1,926) per ounce sold as compared to

Q4 2024, due to a 5% decrease in ounces sold in Q4 2025, a 34% increase in total cash costs and a 4% increase

in sustaining capital expenditures. For 2025, AISC per ounce of gold sold decreased by 4 % to $2,021 (US$1,446)

per ounce sold as compared to the prior year, due to a 21% increase in ounces sold partially offset by 20% higher

total cash costs and 12% increase in sustaining capital expenditures due to increased investment in mine

infrastructure. Investments in new equipment and increased development supported the steady increase in mill

throughput at Eagle River in 2025.

Exploration Update

Drilling Continues to Expand 6 Central Zone

In the 6 Central Zone, drilling continues to confirm the down -plunge continuity of mineralization, demonstrating

similar thickness and grade to previously reported intercepts. Located near existing infrastructure, the zone remains

open at depth and provide s the potential opportunity to establish another new high -grade mining front at

intermediate depths.

Drilling in 311 Targeting Growth Along Strike and Down-Plunge

Drilling during the quarter focused on evaluating the continuity of mineralization to the west and down-plunge to the

southwest. Assays remain pending, but preliminary results confirm the continuation of the mineralized domain.

Results will be incorporated into a resource update to be issued in June 2026.

7

Global Model

Four underground rigs continued drilling global model targets in the fourth quarter. These targets are well advanced

and are a mixture of inferred material and geologic potential. A total of eight global model targets were drilled during

the quarter. Results will be incorporated into the Company’s annual mineral reserve and mineral resource estimate

in June 2026.

Surface Exploration

Surface d rilling continued in the fourth quarter with two rigs at the Mishi and Magnacon deposits. Holes were

designed to test concepts as part of a geological and structural review that included surface mapping. At Mishi,

drilling twinned historic holes for validation purposes, and evaluated potential deep, higher -grade mineralization

beneath existing open pit designs. At Magnacon, holes were designed to confirm the accuracy of historic

underground development designs and evaluate the continuation of underground mineralization. Resource reviews

and updates for the Mishi deposit are expected in Q1 2026 with additional drilling and modelling work to be

completed at Magnacon by Q4 2026.

Resource validation and delineation drilling was completed at the Dorset and Dorset West deposits in the third

quarter, and geotechnical holes were completed in the fourth quarter. Initial metallurgical test work was completed

in the fourth quarter and further sampling and deportment studies have commenced as part of the geometallurgical

program for the deposits.

Helicopter supported drilling continued at both the Cameron Lake Iron Formation and Eagle River Splay Targets.

At Cameron Lake, drilling continued to evaluate a potential large tonnage, lower grade deposit. Approximately 80%

of assays had been received by year end 2025 and further drilling is planned in 2026 after receipt of all assays and

an updated project review.

At the Eagle River Splay, scout drilling evaluated the source of several IP anomalies close to previously reported

drilling. Reported a ssays were weakly anomalous and further drilling is planned in 2026 following reviews

incorporating all drilling, geophysics, geochemical, and mapping results received to date.

Soil geochemical samples were also collected from survey grid lines cut at the Birch target and north diorite areas.

These areas are interpreted to be the continuation of the Eagle River Splay structures further to the southeast.

Assay results are expected early 2026 and will be reviewed in conjunction with the results of IP survey data. Follow-

up scout drilling will be included in helicopter supported drill programs this summer.
