• Exploration teach -in: The Company hosted an exploration teach -in on March 30 th highlighting the

Company's evolving exploration strategy and growing pipeline of targets across its large prospective land

2

packages, providing clearer insight into how Wesdome is methodically advancing resource growth,

replacing reserves, and making new discoveries.

Anthea Bath, President and Chief Executive Officer, commented: "The year is off to a solid start, underpinned by

disciplined execution, demonstrated performance improvements at Kiena, and a strong gold price environment that

is translating into significant margin expansion per ounce. While cost pressures are becoming an industry -wide

focus, we have identified targeted initiatives across areas such as procurement and productivity that are expected

to moderate unit costs in the second half of the year. We are well positioned to deliver on our 2026 guidance.

"Eagle River continued to demonstrate consistent operational performance in the first quarter, with mill throughput

averaging nearly 800 tonnes per day, supported by strong stope productivity, enhanced maintenance practices,

and improved mobile fleet availability. Capital expenditures during the quarter were at their lowest point for the year,

with investment expected to accelerate and peak in the third quarter as we advance planned improvements to camp

and site infrastructure, reinforcing our long-term commitment to this cornerstone asset.

"Kiena is turning a corner. Last year’s initiatives undertaken to improve operational flexibility together with

implementation of our new operating model are delivering measurable results by reducing unplanned delays and

allowing us to mine multiple stopes concurrently. The first quarter ended on a strong note, and that momentum

accelerated into April with production for the month exceeding 7,000 ounces. With the Presqu'île permit now in

hand, high-grade ore is already being stockpiled, and we are pushing development rates higher. We remain firmly

on track to drive meaningful growth in tonnage in the second half of the year.

"The first quarter marked another strong period for the Company, with robust free cash flow generation driving our

cash position to more than $430 million. This financial strength supports a balanced capital allocation approach,

including reinvestment in our operations, maintaining a strong balance sheet, and returning capital to shareholders.

During the quarter, we spent approximately $49 million to repurchase shares in March and with the first phase of

our buyback now complete, we are pleased to announce a second tranche of up to 3 million shares . This reflects

our conviction in Wesdome's intrinsic value and our continued commitment to delivering shareholder returns.

"Looking ahead, our updated technical reports remain on track, with a news release expected in late June outlining

updated life -of-mine plans at both operations based on proven and probable reserves and illustrating upside

potential from ongoing exploration and optimization initiatives. We closed the quarter with an exploration teach -in

designed to give the market a look at the substantial opportunity within our large land packages. With over 220

targets, many of which are in the higher -probability categories, it is clear there is a lot more to discover. The full

picture is coming into focus, and we are looking forward to conveying the long -term vision we have for our assets

at the end of June."

Operating Highlights

During Q1 2026, Eagle River produced 27,846 ounces of gold as compared to 28,999 ounces in Q1 2025. This was

primarily a function of scheduled mine sequence at slightly lower grades compared to Q1 2025 supplemented with

stockpile to utilize mill capacity. Grades processed in Q1 2026 are aligned with planned grade from the mined areas.

Mill throughput of 71,731 tonnes in Q1 2026 was 20% higher than the first quarter of 2025 benefitting from improved

productivity in the mill and greater ore availability . These rates are anticipated to be maintained throughout 2026

demonstrating the “fill the mill” strategy.

Q1 2026 production costs of $577 per tonne were 3% lower than the first quarter of 2025, primarily due to higher

mill throughput leveraging incremental ore feed from stockpile and offsetting escalating input costs on labour,

energy and fuel.

Financial Highlights

In Q1 2026, Eagle River’s gold revenue increased 55% to $178.6 million from $115.5 million in Q1 2025 due to a

higher average realized price of gold sold, partially offset by a 1% reduction in ounces sold.

Cost of sales in Q1 2026 were $45.7 million, an increase of 24% relative to the comparative period in 2025 primarily

due to a $3.6 million increase in mine and mill operating costs due to higher tonnes processed, which spread fixed

costs over a larger production base and reduced unit costs resulting in a reduction in production cost per tonne,

escalating costs of fuel and energy, a $3.9 million change in inventory levels and increased royalties mainly due to

higher gold prices.

Q1 2026 cash costs per ounce of gold sold increased to $1,660 (US$1,210) per ounce sold from $1,327 (US$925)

per ounce sold in Q1 2025 primarily due to an increase in cost of sales and fewer ounces sold in Q1 2026.

In Q1 2026, AISC per ounce of gold sold increased by 16% to $2,216 (US$1,616) per ounce sold as compared to

Q1 2025, due to a 1% decrease in ounces sold in Q1 2026, and a 24% increase in total cash costs, partially offset

by a 17% decrease in sustaining capital expenditures.

Exploration Update

Drilling Continues to Expand 6 Central Zone

In the 6 Central Zone, growth 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 provides the potential opportunity to establish another new high-grade mining

front at intermediate depths.

Drilling for Growth in the 800 Zone

Growth drilling during the quarter had two primary objectives. The first objective was to target a near surface area

(within 400 metres of surface) where a gap in drilling coincides with a projected up -plunge continuation of

mineralization. The second objective focused on an area representing the projected down -plunge continuation of

mineralization at depth. Early results support block model projections of grade. Drilling will continue into the second

quarter.

Conversion and Growth Drilling in Falcon 311 Zone

Growth drilling evaluating the continuation of mineralization to the west and down -plunge to the southwest is

ongoing, complementing conversion drilling of three global model targets. Assays remain pending, but preliminary

results confirm the continuation of the mineralized domain in both directions at grades supporting block model

results.

Global Model

Two underground rigs continued drilling global model targets in the quarter. These targets are well advanced and

are a mixture of geologic potential with minor Inferred material. A total of five global model targets were drilled during

the quarter including one target in the 711 Zone, one in the 300 Zone, and three in the Falcon 311 Zone. Drilling of

deeper portions of the 300 Zone continued into the second quarter.

Surface Exploration

Surface drilling continued with one rig at the Dorset deposit, evaluating the potential link between Dorset Main and

Dorset West, as well as down -plunge continuity. Geometallurgical sampling for leach and recovery test work, and

deportment studies, continues as part of overall deposit resource evaluation.

Deep holes from surface testing down -plunge continuation of mineralization in the 800 and 6 Central zones

commenced during the quarter. The 800 Zone hole ERS-2026-001-W1 was completed at 1701 metres. Results will

be reported in the second quarter. The 6 Central hole ERS-2026-003-W1 still in progress.

At Abbey Lake, a gradient array IP geophysical survey was completed along an 8-kilometre trend, aimed at mapping

out continuation of quartz veins and sulphide rich horizons highlighted by previous work , including geologic

mapping, local IP surveys, and scout drilling. Survey results and reporting are expected in the second quarter, with

drill programs scheduled for the third quarter.

Operating Highlights

In Q1 2026, Kiena produced 17,457 ounces, compared to 16,693 ounces produced in Q1 2025, which is driven by

higher mine production, primarily from the addition of Presqu’île ore offsetting lower tonnage, at a higher grade, in

Kiena Deep due to preventative maintenance on the hoist and mill reline in Q1 2026 . Average grade in Q1 2026

was 10.0 g/t, slightly lower than 10.8 g/t in Q1 2025, and consistent with the reserve grade. Presqu’île ore grades

are lower than Kiena Deep, with the balance between the two feed sources aligned with the plan.

Mill throughput of 54,950 tonnes in Q1 2026 was 13% higher than the first quarter of 2025 due to availability of

additional mill feed from Presqu’île.

Production costs per tonne were $591 per tonne in Q1 2026, an increase from $489 per tonne in Q1 2025, driven

by ongoing competitive pressures on labour pricing, additional contractors to support maintenance and operations

to improve equipment reliability, fuel price increases, and investment in operating model development to provide a

more stable and predictable operation. Presqu’île tonnes are all from development which is at a higher unit cost

than production stoping contributing to the overall increase from Q1 2025. Several initiatives are underway to reduce
