Golden Sky Minerals Corp. (TSXV:AUEN) and Boliden Mineral Canada Ltd. have entered into a definitive agreement granting Boliden the right to earn up to an 80  per cent interest in Golden Sky’s Rayfield property by investing C$20 million in exploration and payments over six years.

After earn-in, the contiguous Rayfield and Gjoll properties will enter a joint venture with Golden Sky holding 20 per cent and both parties funding pro rata thereafter.

Project scale and location

The combined Rayfield‑Gjoll property covers some 87,660 hectares located under 60  kilometres northwest of Kamloops, British Columbia, in the Quesnel Trough — a prolific porphyry copper belt hosting major mines such as Highland Valley, Gibraltar, New Afton, Copper Mountain and Mount Polley.

This region offers robust infrastructure, all-season access and significant under-explored opportunity.

Golden Sky perspective

John Newell, President and Chief Executive Officer of Golden Sky Minerals, described the arrangement as “transformational for Golden Sky.” He added, “Boliden’s decision to collaborate with us on Rayfield‑Gjoll validates the district-scale copper‑gold potential of this project. It allows us to preserve our tight share structure while aggressively advancing exploration in one of Canada’s most prolific mineral belts.”

Prior work includes identification of large-scale geophysical anomalies and intercepts showing copper-gold mineralization (e.g., a chargeability-resistivity anomaly ~600 m by 1,100 m at Rayfield, multiple drill intersections with elevated copper grades), and promising soil anomalies at the Gnome, Semlin and Mowich targets, indicating prospective porphyry systems.

The agreement marks a strategic milestone for Golden Sky. Boliden’s commitment brings robust funding, technical endorsement and operational leverage. As exploration ramps up within the Quesnel Trough, the joint venture structure positions both parties to tap into a highly mineralized area while preserving Golden Sky’s equity buffer.

Shares of Golden Sky Minerals (TSXV:AUEN) are down by 5.88 per cent trading at C$0.48 as of 3:10 pm.
