RSS SubscribeVancouver, British Columbia, November 12th, 2026 – Cosa Resources Corp. (TSX-V: COSA) (OTCQB: COSAF) (FSE: SSKU) (“ Cosa ” or the “ Company ”) is pleased to announce results of the summer drilling program at the Company’s Darby (“ Darby ”) project (Figure 1). Darby is a joint venture (the “ Joint Venture ”) between Cosa and Denison Mines Corp. (“ Denison ”) ( TSX: DML) ( NYSE American: DNN) and is located 10 kilometres west of Cameco’s Cigar Lake Mine. Cosa is the project operator and holds a 70% interest with Denison holding a 30% interest.
Keith Bodnarchuk, President and CEO, commented: “Cosa’s second drill program at Darby has highlighted the Gamma and Bravo trends for follow-up winter work and continues to demonstrate the prospectivity of Darby as a discovery-ready project alongside our Murphy Lake North joint venture with Denison Mines. Intersecting anomalous radioactivity at the Gamma trend, paired with a broad zone of structure and alteration that remains open in multiple directions, reinforces our belief in the increasing discovery potential at Darby, and we are excited to return for fully funded follow-up drilling in 2027. We aim to update the market regarding 2027 plans in the coming weeks which are scheduled to include simultaneous drilling at both the Darby and Murphy Lake North joint ventures.”
