Cosa Resources (TSXV: COSA; OTCQB: COSAF) appointed David Cates, President and CEO of Denison Mines (NYSE: DNN), as Strategic Advisor on October 29, 2025. Cosa holds a 70% interest and operates multiple joint ventures with Denison at Murphy Lake North, Darby, and Packrat.
The appointment follows a transformative property acquisition earlier in 2025 and precedes a planned winter 2026 exploration program at Darby and Murphy Lake North.
Cosa Resources (TSXV: COSA / OTCQB: COSAF) identified multiple high‑priority, drill‑ready targets at the Darby uranium project in the eastern Athabasca Basin, 10 km west of Cigar Lake. Cosa operates the joint venture and holds 70% (Denison 30%).
Priority targets are on the Delta and Charlie trends after relogging 31 historical holes; notable intercepts include DB‑27 (52 m anomalous sandstone; 0.13% U3O8 over 0.3 m in basement) and DB‑09 (42 m continuous anomalous basal sandstone). Winter 2026 drilling plans and budgets are being finalized with Denison.
Cosa Resources (OTCQB: COSAF) has expanded its 100% owned Orbit Project in Saskatchewan's Athabasca Basin region through strategic land acquisition. The project, located 21 kilometers south of Cameco's Key Lake Mill, now covers over 15,000 hectares of uranium exploration territory.
The expansion includes areas with coincident radon, helium, and hydrogen anomalies identified through remote sensing. Two significant target areas were identified: ORS-1 (1,000 x 1,000 metres) and ORS-2 (750 x 600 metres). Recent staking has added 3 kilometres of drill-ready conductive strike length. The project benefits from having no sandstone cover and proximity to essential infrastructure including highways, powerlines, and permanent camp facilities.
Cosa Resources (OTCQB:COSAF) announced its participation in the Metals Investor Forum (MIF) in Vancouver on September 26-27, 2025. CEO Keith Bodnarchuk will present on September 26th at 2:40 PM local time, discussing the company's exploration progress and drilling results at the Murphy Lake North uranium project, a 70/30 joint venture with Denison Mines.
Additionally, the company has engaged Machai Capital for a 3-month digital marketing campaign starting September 2025, with a total compensation of C$150,000. The campaign will include comprehensive digital marketing services, subject to TSX Venture Exchange approval.
Cosa Resources (OTCQB: COSAF) has announced significant findings from its ZTEM survey at the Astro uranium project in Saskatchewan's Athabasca Basin. The survey, funded by partner Global Uranium, has identified over 25 kilometers of prospective east-northeast trending conductive strike length.
The comprehensive survey, covering 1,487 line-kilometers, revealed conductive trends following a break between magnetic high and low zones - a setting favorable for uranium deposits. This marks the first comprehensive EM survey in the area, with results significantly upgrading the project's exploration potential. The conductive corridors identified are similar to those hosting tier-1 deposits like Cigar Lake and McArthur River mines.
The project is part of an option agreement announced in April 2025, allowing Global Uranium to earn up to 80% interest in the Astro project over five exploration stages.
Cosa Resources (OTCQB: COSAF) has announced significant findings from its summer drilling program at the Murphy Lake North Uranium Project in Saskatchewan's eastern Athabasca Basin. The company has identified a two-kilometer stretch of strong sandstone alteration and graphitic faulting at the Cyclone Trend.
The drilling program, totaling 3,323 metres across eight holes, revealed highly prospective geology for eastern Athabasca-style uranium deposits. Key findings include up to 30 metres of unconformity relief and significant basement structures. Cosa has successfully met its sole-fund obligation and now owns an irrevocable 70% interest in the project, with Denison Mines holding the remaining 30%.
The company plans to conduct follow-up drilling in early 2026, with drilling equipment remaining on-site to minimize future operational costs.
Cosa Resources (OTCQB: COSAF) has initiated a 3,000-metre summer drilling program at the Murphy Lake North Uranium Project in Saskatchewan's eastern Athabasca Basin. The project is a joint venture with Denison Mines, where Cosa holds a 70% interest and operates the project, while Denison maintains a 30% stake.
The drilling program, the largest to date for the project, will include up to eight drill holes targeting the Hurricane and Cyclone trends. The program follows up on significant sandstone alteration discovered during winter drilling at the Hurricane trend. The project is strategically located 2.7 kilometers east of the Hurricane deposit, which is notably the world's highest-grade Indicated Uranium Resource.
