Kiena Overtakes Eagle River in Q2 as Wesdome Rebalances Its Two-Mine Portfolio

Wesdome Gold Mines’ second-quarter production changed the balance of its two-mine portfolio even though consolidated output barely moved.

The Canadian producer made 43,823 ounces of gold in the three months ended June 30, up 2% from a year earlier. The important split was underneath that headline: Kiena produced 22,026 ounces, up 28%, while Eagle River fell 15% to 21,797 ounces as planned sequencing pushed its average processed grade down to 9.7 grams per tonne from 16.9 g/t a year earlier.

That makes Kiena the more important operating test for Wesdome in the second half of 2026. The Quebec mine has spent several quarters trying to improve equipment availability, increase the number of active mining horizons and bring the Presqu’île zone into the production mix. Q2 is the first period in which that work is visible enough to offset a weaker quarter at Eagle River.

Kiena milled 62,515 tonnes in Q2, 24% more than a year earlier, at an average grade of 11.1 g/t. Eagle River milled 72,439 tonnes, 49% more, but the lower grade meant the additional throughput did not translate into higher ounces. For investors, the contrast matters because Wesdome’s growth case increasingly depends on filling underused mill capacity with more predictable tonnes rather than relying on exceptionally high grades from a small number of stopes.

Presqu’île is central to that shift. Wesdome said the first stope was expected to enter production in July, broadening Kiena’s active mining base beyond Kiena Deep. Management has previously said the operation had moved from one active mining horizon to three, while development and ventilation work were intended to reduce the variability that constrained Kiena in earlier periods.

The reserve update published in June strengthens the case for spending that capital. Wesdome lifted combined proven and probable reserves at Eagle River and Kiena by 17% to about 1.4 million ounces and established an eight-year reserve life at both mines through 2033. Eagle River’s reserves rose 39% to roughly 676,000 ounces, while Kiena held about 711,000 ounces after depletion. The company expects the two mines to contribute roughly equal shares of production by 2028.

The near-term economics, however, still hinge on execution. Wesdome’s 2026 guidance calls for 180,000 to 205,000 ounces of consolidated production at all-in sustaining costs of US$1,525 to US$1,700 an ounce. Kiena is expected to produce 75,000 to 90,000 ounces this year, with the second half weighted toward stronger output as Presqu’île ramps and Kiena Deep becomes more flexible.

The first-half numbers leave that guidance achievable but not automatic. Wesdome produced 89,126 ounces through June, only 1% more than a year earlier. Eagle River’s first-half output was down 9%, while Kiena was up 17%. To reach the midpoint of full-year guidance, the company needs roughly 103,000 ounces in the second half - a meaningful step-up from the first six months.

That requirement makes grade reconciliation at Eagle River and stope availability at Kiena the two metrics that matter most. Eagle River’s Q2 grade decline was planned, and management expects grades to improve in the second half. The risk is that underground sequencing rarely behaves perfectly: development delays, dilution, equipment availability or slower access to higher-grade stopes can turn a planned quarterly grade dip into a longer cost problem.

At Kiena, the challenge is different. Presqu’île adds another source of ore and should reduce dependence on Kiena Deep, but new stopes must enter the schedule without introducing fresh dilution, development or ventilation constraints. The mine’s 2026 guidance assumes an average grade of 8.0 to 9.5 g/t, so the 11.1 g/t achieved in Q2 provides some cushion if throughput remains stable.

Wesdome is also asking investors to judge the operating plan alongside a more explicit capital-return framework. In June, the company declared a C$0.0306 quarterly dividend and expanded its share-buyback programme after repurchasing more than 4% of its outstanding shares since the programme began. The company has also outlined substantial free-cash-flow potential at current gold prices, but those returns will be easier to sustain if Kiena’s growth lowers unit costs rather than simply absorbing more capital.

That is why Q2 is more useful than the 2% consolidated production increase suggests. Wesdome no longer needs Kiena merely to stop being the weaker mine. It needs Kiena to become a repeatable second production engine while Eagle River shifts toward higher mill utilisation and a broader reserve base.

The next proof point is the second-half production profile. If Presqu’île adds dependable tonnes, Kiena Deep maintains multiple active horizons and Eagle River grades recover as scheduled, Wesdome can move toward the 185,000-to-230,000-ounce annual production range it has outlined for 2027 and 2028 while returning more cash to shareholders. If any of those pieces slip, the company’s new eight-year reserve lives will remain valuable, but the market will have to wait longer for the operating leverage they are supposed to create.
