Selkirk Copper (TSXV: SCMI) has completed its Phase 1 drill program at the Minto copper-gold-silver mine, marking a major milestone in the company’s efforts to restart the Yukon-based operation. The program, which comprised over 52,280 meters across 175 holes, represents one of the largest exploration campaigns in the territory over the last decade.
The drilling effort utilized four diamond rigs and focused on resource expansion across six primary zones. Initial findings indicate a high rate of success, with approximately 87% of the holes intersecting significant mineralized lenses.

Notable results emerged from the Minto North west zone, where drilling suggests the mineralized volume has at least doubled compared to 2025 estimates. Previously released results from this zone include intersections of 3.52% copper, 3.51 g/t gold, and 17.04 g/t silver over 16.7 metres in hole 25SCM043.

Beyond resource expansion, exploration drilling identified a new mineralized lens in Area 118, located roughly 120 meters below the existing resource. Intersections here include 0.76% copper, 0.42 g/t gold, and 3.56 g/t silver over 29.7 metres. This discovery remains open in several directions, with the current footprint measuring 500 by 400 metres, and is expected to be a priority for the upcoming Phase 2 campaign. Deep-hole exploration also confirmed that mineralization continues at depth beneath the Minto Main and Minto East areas, with intercepts recorded as deep as 650 meters.
Management expects a steady flow of assay results through the end of May. This data will be integrated into an updated mineral resource estimate and a preliminary economic assessment, both of which are slated for completion in mid-2026.

Separately, as of April 1, Selkirk Copper has formally assumed full responsibility for site operations and care and maintenance activities of the Minto mie. This transition is part of a broader framework agreement between the company, the Selkirk First Nation, and the Yukon Government. The company is now pivoting toward project readiness, focusing on technical data collection and engineering trade-off studies to support a potential restart decision scheduled for mid-2027.

“This marks an important milestone as the site transitions away from a focus on care and maintenance, towards resource expansion, engineering and trade-off studies, and site-wide technical data collection, to inform a potential restart decision in mid-2027,” commented Colin Joudrie, CEO of Selkirk Copper.
In conjunction with the transition to site operations, the company has appointed Shiro Rae as Director of Business Planning and Site Operations. Rae, a geoscientist and economist with nearly two decades of industry experience, will oversee site-based work programs including safety, camp operations, and environmental protocols.
