Core Silver Corp. and Arcus Development Group Inc. have commenced a 3,000-metre diamond drilling program at the Touleary Project in the Yukon Territory, located approximately 115 kilometres south of Dawson.

The program focuses initially on the 2011 Discovery Zone, where historical drilling was limited to a 335-metre strike length. The current campaign is testing an interpreted strike-length potential of approximately 3.5 kilometres. Historical high-grade intercepts from the zone include hole TL-11-005, which returned 2.25 metres grading 7.18% copper, 3.55 g/t gold, 4.30% zinc, and 116 g/t silver from 115.62 metres.

Under an option agreement dated April 26, 2026, Core Silver secured the right to earn a 20% interest in the project by incurring at least $2,000,000 in exploration expenditures by April 26, 2027.

“The drill is turning at the Touleary Project,” said Nick Rodway, President and CEO of Core Silver. “This is the first drill program at the Project since 2011 and represents an important step toward evaluating the broader scale of the mineralized system. The program is designed to follow up the significant copper-gold-zinc-silver intersections encountered by historical drilling while also providing flexibility to test compelling undrilled targets elsewhere on the Project.” — Nick Rodway, President and CEO of Core Silver

The 2026 program will also test undrilled regional targets such as Target-4 and Target-8, which feature coincident geophysical anomalies and anomalous soil sample assays.
