[{"type":"text","content":"Cosa Reports Anomalous Radioactivity in Multiple Drill Holes at the Murphy Lake North Joint Venture with Denison MinesVancouver, British Columbia--(Newsfile Corp. - April 13, 2026) - Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) (\"Cosa\" or the \"Company\") is pleased to report the intersection of anomalous radioactivity in multiple drill holes and completion of the winter 2026 drilling program at the Company's Murphy Lake North Project (\"MLN\" or the \"Project\"). MLN is a joint venture (the \"Joint Venture\") between Cosa and Denison Mines Corp. (TSX: DML) (NYSE American: DNN) (\"Denison\") and is located 3 kilometres east of IsoEnergy's Hurricane deposit in the eastern Athabasca Basin, Saskatchewan (Figure 1). Cosa is the operator and holds a 70% interest with Denison holding a 30% interest.HighlightsRadioactivity intersected in three drill holes Radioactivity remains open in multiple directions including for at least 600 metres along strike to the east and 600 metres to the west within the larger kilometre-scale Cyclone alteration zoneDepth of the radioactivity is shallow at approximately 260 metres vertically from surfaceCyclone trend structural corridor is over 100 metres wide and hosts significant alteration consistent with major eastern Athabasca uranium depositsKeith Bodnarchuk, President and CEO, commented: \"Intersecting radioactivity in multiple drill holes is a tremendous result for Cosa, emphasizing the potential size and scale of this mineralizing system. The radioactivity alone is significant, but when factoring in the open space, depth, strong alteration and structure, this suggests we may be on the cusp of even more exciting results. With strong support from Denison Mines, assays pending, a healthy treasury, and numerous follow up targets, 2026 is shaping up to be a transformational year for Cosa.\" Andy Carmichael, Vice President of Exploration, commented: \"Intersecting 5 metres of continuously anomalous radioactivity in the second round of drilling at Cyclone significantly upgrades the trend. Though warming conditions curtailed follow up, the additional holes resulted in additional radioactive intercepts separate from that of MLN26-013 and a deeper understanding of the trend's geology which will be invaluable during future drilling.
