Cosa Announces Winter 2026 Drilling Plans for Joint Ventures with Denison Mines
Denison-backed explorer initiates 2026 winter campaign at 52-week highs, leveraging strategic funding to test targets near Cigar Lake.
On January 21, 2026, Cosa Resources announced the specifics of its winter 2026 drilling programs for the Darby and Murphy Lake North (MLN) uranium projects in the Athabasca Basin, Saskatchewan. * Darby Project: Approximately 2,500 metres of drilling are planned to test high-priority targets derived from 2025 core relogging. Drilling is scheduled to commence before the end of January 2026. Targets focus on areas with historical intersections of uranium mineralization and untested structures. * Murphy Lake North (MLN): Approximately 1,200 metres are planned, starting in March 2026. This program aims to follow up on 2025 results and test new parallel trends. * Partnership: Denison Mines (TSX: DML), the company's largest shareholder and Joint Venture partner, is participating in funding the MLN exploration to maintain its 30% interest.
While this news is routine in nature (the announcement of a drill schedule), it is Positive within the current context of the company's development. * Validation of Targets: Denison Mines’ decision to fund its 30% pro-rata share at Murphy Lake North serves as a technical validation of Cosa's targets. Denison is rigorous with capital allocation; their continued participation suggests they see geological merit in the follow-up work. * Execution of Capital: Following the C$7.5 million financing closed in December 2025, this release confirms the immediate deployment of capital into the ground. * Timeline Clarity: The scheduling (Darby in Jan, MLN in March) provides the market with a clear timeline for potential catalysts (assay results) heading into Q2 2026. * No Discovery Yet: It is critical to note that this news releases intent, not results. The materiality is limited to operational progress rather than economic discovery.
Cosa Resources is a Canadian uranium exploration company focused on the Athabasca Basin in Saskatchewan. * Flagship Project (Murphy Lake North - MLN): A Joint Venture with Denison Mines (Cosa 70%, Denison 30%). Located in the eastern Athabasca Basin, it is on trend with the Hurricane Deposit (IsoEnergy). Recent drilling (Summer 2025) identified significant sandstone alteration and structure, though high-grade mineralization has not yet been intersected. * Darby Project: Also a JV with Denison (Cosa 70%, Denison 30%). Located 10km west of the Cigar Lake Mine. The winter 2026 program focuses on the Delta and Charlie trends, testing conductivity and historical uranium indicators. * Other Assets: Ursa, Orion, Astro, and Orbit projects (100% owned).
