Selkirk Copper drills new lenses at Minto Mine, Yukon

Vancouver, BC – TheNewswire - June 10, 2026 – Global Stocks News - Sponsored content disseminated on behalf of Selkirk Copper Mines. On June 3, 2026 Selkirk Copper Mines (TSXV: SCMI) (FRA: IO20) (OTCQB: SKRKF) released final results from its Phase 1 drill program , conducted between August 2025 and April 2026. One year ago, Selkirk First Nation (SFN) purchased the former Minto Mine out of bankruptcy, then partnered with the Frank Giustra-backed Fiore Group to form Selkirk Copper Mines.

SCMI is derisking the Minto Mine through exploration, resource expansion, engineering and mine planning, with the goal of establishing a 12-15 year mine life prior to production restart. “The Phase 1 drill program has achieved exceptional results at each of the five primary target areas within the mine footprint,” stated Selkirk President & CEO Colin Joudrie in the June 3, 2026 press release. “We have expanded known zones of mineralization , discovering several higher-grade copper-gold-silver intervals within known zones, discovering several new lenses of high-grade mineralization , and discovering mineralization at depths previously undrilled .” Click Image To View Full Size   “The team successfully completed the largest drill program in the Yukon over the last ten years and did so safely, on-budget, and on-schedule through one of the coldest falls and winters on record,” added Joudrie. “These results are being incorporated into an updated Mineral Resource Estimate and Preliminary Economic Assessment that remains on track for completion in mid-2026.” Click Image To View Full Size   Above: plan view of the Minto Mine Property area showing surface projections of mineralized zones relative to Phase 1 and Phase 2 drill collars. The drilling completed at Area 118 has confirmed discovery of a high-grade mineralized lens at depth beneath the previously known resources in this area. This has been designated the 301 Lens .

It has been intersected by widely spaced drill holes over an area approximately 500 x 300 metres, with thicknesses ranging from 4 to 20 metres thick. In the central part of the Mine area, recent drilling has delineated mineralization underground between two historical open pits , the Minto Main Pit and the Area 2 Pit. This has been designated the 117 Lens .

It has been delineated over an area approximately 300 X 250 metres and remains open to the west.

Drill hole 26SCM137 intersection of 0.46% Cu, 0.14 g/t Au, and 1.57 g/t Ag (0.58% CuEq) over 69.6 m, from 13.7 m.

Drilling at Minto North focused on expanding and delineating the Minto Northwest zone. The Minto North West Zone returned some of the highest grade and highest thickness drill intercepts during the Phase 1 drill program. This area has been designated as the 202 Lens for purposes of geological modelling and resource estimation and is notably higher-grade than other parts of Minto North.

At Copper Keel , drill hole 26SCM158 returned an intersection of 0.53% Cu, 0.29 g/t Au, 2.18 g/t Ag (0.77% CuEq) over 9.9 metres.

Four drill rigs are now active, targeting approximately 50,000 metres with a focus on resource expansion, infill drilling, geotechnical drilling, and geo-metallurgical data collection to support increased resource confidence and mine planning for planned feasibility study work.

Drilling productivity has been significantly higher than Selkirk expected, averaging 120 metres per day, compared to 94 metres per day during the Phase 1 program. On May 25, 2026, Selkirk announced that it has closed a further investment by Selkirk First Nation for aggregate gross proceeds of C$500,250 at a price of $1.15 per share. The investment was completed in connection with the exercise of Selkirk First Nation’s pro rata participation right under its existing agreement with Selkirk Copper.

In this excerpt from a recent interview with Crux Investor, Selkirk Copper CEO Colin Joudrie explains how the removal of a gold-silver stream has empowered Selkirk to operate as a full co-product mine. “We are advantaged by the bankruptcy,” Joudrie confirmed to Crux Investor. “We have removed a gold-silver stream that sat astride this asset all the way back to 2007. This is not a by-product copper, gold, silver mine. This is a co-product mine .” “Sixty-five percent of the revenue is from copper, 35% from gold and silver, the majority of which is gold.

Removal of that stream is a game-changer for the asset from a financial and operating perspective. In the broader metals complex, the price changes from May of 2023, we’re up 150-200% across those three metals, and that doesn’t look like it’s changing anytime soon.” “Copper is trading just above $14,000 a ton in London, roughly $500 shy of its all-time high set in January, and Wall Street thinks it has further to run,” reports Oilprice.com on June 3, 2026. “Grid expansion, electric vehicles, data center construction, and clean energy investment continue to absorb copper at a pace that the market struggled to meet even before the supply shocks.” Results from the 50,000-metre Phase 2 drill program are expected to be released throughout the summer and fall of 2026.
