Cosa Announces Winter 2026 Drilling Plans for Joint Ventures with Denison Mines

Core Insights - Cosa Resources Corp. is set to commence drilling at its Darby and Murphy Lake North projects, which are joint ventures with Denison Mines Corp. The company holds a 70% interest in both projects, while Denison holds 30% [1][3][26]. Drilling Plans - Approximately 2,500 meters of drilling are planned at the Darby project in winter 2026, focusing on high-priority targets identified from previous core relogging and reinterpretation [4][26]. - At Murphy Lake North (MLN), around 1,200 meters of drilling will follow up on summer 2025 results, targeting a gap in drilling due to a lake that prevents summer access [9][11]. Target Areas - The Gamma trend at Darby has over 4 kilometers of conductive strike length, with historical drill holes indicating potential for uranium deposits [4][5]. - Initial target areas at Darby include locations with historical intersections of uranium mineralization and structures that have not been tested [3][4]. - At MLN, the focus will be on the Cyclone trend and an additional parallel trend to the south, where previous drilling has shown promising results [6][15]. Exploration Objectives - The company aims to evaluate high-priority targets under frozen lakes and conduct a property-wide DC-Resistivity survey in spring to identify prospective targets for summer drilling [3][10]. - The winter drilling program at MLN will also assess intensely graphitic rocks and faulting intersected in previous drilling [9][11]. Project Background - The Darby project is located 10 kilometers west of Cameco's Cigar Lake Mine and has multiple prospective conductive trends with historical intersections of weak uranium mineralization [12][26]. - MLN is situated 2.7 kilometers east of the Hurricane deposit, which is known for being the world's highest-grade indicated uranium resource [14][15]. Company Overview - Cosa Resources is a Canadian uranium exploration company with a portfolio of approximately 237,000 hectares in the Athabasca Basin, focusing on underexplored projects [23][24]. - The company has a strategic collaboration with Denison Mines, enhancing its access to highly prospective uranium exploration projects [24].
