Core Silver Corp. (CSE: CC, OTCQB: CCOOF, FSE: 8ZR) and Arcus Development Group Inc. (TSXV: ADG) have commenced a 2026 diamond drilling program at the Touleary Project in Yukon Territory, approximately 115 kilometers south of Dawson, according to a joint press release.

The program is planned for approximately 3,000 meters and marks the first drilling at the project since 2011. Initial drilling is focused on the Discovery Zone, where historical drill holes returned copper, gold, zinc, and silver intersections, including hole TL-11-005, which yielded 2.25 meters at 7.18% copper, 3.55 g/t gold, 4.30% zinc, and 116 g/t silver.

Historic drilling tested approximately 335 meters of strike length to a vertical depth of around 250 meters. The total interpreted strike length of the Discovery Zone geophysical signature is approximately 3.5 kilometers, leaving the majority untested.

The 2026 program is also designed to test two additional targets, Target-4 and Target-8, neither of which has been subject to historic drilling. Target-4 is associated with a three-kilometer linear geophysical signature and anomalous copper and zinc soil samples. Target-8 is identified by an interpreted vent complex with coincident copper, gold, silver, and zinc soil and hand-pit sample anomalies.

"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," said Nick Rodway, President and CEO of Core Silver.

The Touleary Project is characterized as a volcanogenic massive sulphide (VMS) system hosted in Devonian-Mississippian age submarine volcanic rocks of the Finlayson Assemblage.
