Cosa Resources – 13 Drill Holes Along The Cyclone Trend Encountered Strong Alteration, and Several Intersected Intervals Of Elevated Radioactivity — The KE Report

Keith Bodnarchuk, President and CEO of Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU), joins me to review the 6,700+ meter 13-hole summer drill program along the Cyclone Trend at the Company’s Murphy Lake North (“MLN”) project. We also discuss the upcoming drill mobilization for their Darby Project, and for the Aurora Project in the near future.

Murphy Lake North and Darby are both joint venture projects between Cosa and Denison Mines Corp. (TSX: DML) (NYSE American: DNN). Cosa is the project operator and holds a 70% interest with Denison holding a 30% interest on both properties. MLN is located three kilometres east of IsoEnergy’s Hurricane deposit, in the eastern Athabasca Basin, Saskatchewan, and was the focus of this summer program’s drill results.

Highlights

Multiple zones of structurally controlled alteration and elevated radioactivity remain open along strike for several hundred meters and on multiple sections
Drilling evaluated multiple structures over 650 metres of strike length with all 13 drill holes intersecting strong structure and/or alteration
Summer 2026 drilling prioritized unconformity targets with significant room for basement-hosted mineralization remaining
With $16 million in the treasury, Cosa remains fully funded for a significant follow up drilling campaign

The 13-hole, 6,752 metre drill program followed up winter results at the Cyclone trend highlighted by 5.0 metres averaging 0.55% U3O8 (308.5-313.5 metres) in MLN26-013 including a 0.5 metre subinterval of 1.70% U3O8 (310.5-311.0 metres). Summer drilling targeted the Cyclone trend over a 650-metre strike length extending 400 metres west and 250 metres east of MLN26-013. All 13 summer drill holes intersected moderate to strong alteration and/or structure, and several drill holes intersected intervals of elevated radioactivity.

Drilling identified two prominent faults, the N- and S-faults, which are generally located along the northern and southern edges of the Cyclone graphitic basement unit. The N-fault is the most prominent basement structure intersected on the project and hosts the zone of strong basement alteration intersected by winter 2026 drill hole MLN26-017.

Next Steps:

With C$16 million the treasury, the Company remains well-funded for a significant follow up winter campaign at Murphy Lake North. Immediate follow up targets include the uranium pathfinder element enriched basement alteration zone intersected by MLN26-017 and MLN26-020C1, the S-fault, and the strike extensions of the N-fault.

Additionally, the Company expects to announce commencement of drilling at the Darby and Aurora projects in the coming days.
