Vancouver, 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).

Denison Mines' 168.7% surge is powered by the final investment decision on Phoenix, high-grade discoveries and reinforcing its long-term low-cost growth story.

Denison Mines is advancing the Phoenix ISR uranium project, targeting first production by mid-2028 and rapid payback with a ~73% IRR. Phoenix's high-grade, low-cost structure (~$18/lb AISC) and front-loaded extraction underpin strong margins, but project valuation is highly sensitive to uranium prices. DNN trades at a significant premium to Phoenix's NPV, reflecting market optimism for ISR execution, future uranium prices, and portfolio extension potential.

DNN advances Phoenix ISR uranium mine after approvals, targeting 2028 production and aiming to deliver low-cost supply as global uranium markets tighten.
