Evolution Mining Limited bumped up its group gold resource and reserve numbers in its latest annual update, offering a clearer look at mine longevity. As of Dec. 31, 2025, the Sydney-based miner logged 31 million ounces in Mineral Resources and 12 million ounces in Ore Reserves.
That’s now coming to the fore as gold miners face scrutiny over more than just production—they’re also under the microscope for their ability to replenish what they mine. Mineral Resources refer to metal estimates likely to be extracted, while Ore Reserves represent the more concrete, economically viable chunk that actually factors into mine planning.
Evolution ended Friday at A$12.15, rising 2.10%. Shares reached as high as A$12.44 during the session, with roughly 5.56 million shares changing hands. The stock still sits well under its 52-week peak of A$17.75, according to market data.
The company reported a 0.9 million ounce, or 3%, lift in gold Mineral Resources after accounting for depletion, with gains led by Cowal in New South Wales and the Northparkes open pits. Gold Ore Reserves also moved up, rising 0.5 million ounces, or 5%, on contributions from Cowal and the Red Lake tailings.
Managing Director and Chief Executive Officer Lawrie Conway pointed to the update as evidence of the portfolio’s “scale and longevity”. Conway also flagged “clear potential” for additional copper resources near Ernest Henry and Northparkes in the coming year. ASX Announcements
Cowal still stands out as the key swing asset. Evolution pointed to resource and reserve gains there, helped by drilling extensions south of Dalwhinnie and deeper work at Regal. Those results, according to Conway, boosted confidence in the company’s mineable inventory and reflected what he described as “disciplined resource delineation”. ASX Announcements
Not everything moved higher. Copper Mineral Resources dropped 200,000 tonnes, down 4% to 4.2 million tonnes. Copper Ore Reserves slipped as well, losing 100,000 tonnes—also a 4% cut—to 1.3 million tonnes. Depletion at Ernest Henry and Northparkes, along with a Marsden update, pressured copper figures.
Evolution is sticking with its fiscal 2026 outlook: gold output seen between 710,000 and 780,000 ounces, copper at 70,000 to 80,000 tonnes. The all-in sustaining cost remains projected at A$1,640 to A$1,760 per ounce.
The competitive picture looks a bit muddled. Among comparable ASX gold stocks tracked by market data, Northern Star Resources edged up 0.81% on Friday, but Genesis Minerals slipped 1.20%. That divergence points to Evolution’s advance being largely driven by its reserve update, rather than any broad sector push.
Still, there are caveats. The maths behind reserves leans hard on assumptions: Evolution applied A$3,000 per ounce for gold and A$13,000 per tonne for copper in its Ore Reserves. If prices slip, costs climb, grades come in softer, or schedules slip, the amount classified as economic could shrink.
Eyes now turn to the June-quarter results, landing July 15. The Northparkes expansion study, still on the horizon, isn’t due until the end of fiscal 2027. In the meantime, investors are left waiting to see if those new ounces will actually shift from technical inventory into funded mine plans.
