Cosa Resources – Winter Drilling Has Commenced At Darby Project, With Murphy Lake North To Follow

Keith Bodnarchuk, President and CEO, and Andy Carmichael, VP of Exploration of Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) , both join me to review the news released on January 28th which announced drilling has commenced at the Company’s Darby project, with drilling at Murphy Lake North (MLN) to follow. Darby and MLN are joint ventures between Cosa and Denison Mines Corp. (TSX: DML) (NYSE American: DNN) and are located 10 kilometres west of Cameco’s Cigar Lake Mine and three kilometres east of IsoEnergy’s Hurricane Deposit, respectively, in the eastern Athabasca Basin, Saskatchewan. Cosa is the operator of both projects and holds a 70% interest with Denison holding a 30% interest in each.

 

Keith starts us up highlighting the prospective geology and historic exploration work that made the Darby Project a vital component of the JV transaction with Denison. The recent identification of new drill targets as results from further analysis supports Cosa’s thesis that Darby is a mature, discovery-ready project that will receive drilling targeting uranium mineralization in the year to come.

 

We outline that approximately 2,500 metres are planned at Darby in winter 2026 to test initial priority targets identified that came as a result of extensive historical drill core and data review at the Delta and Charlie trends by Cosa’s Chairman Steve Blower and VP Exploration Andy Carmichael; as they relogged all historical Darby drill holes from prior project operators in June of this year. Their work confirmed desktop interpretations and generated immediate follow-up targets.

 

Andy outlines that Priority targets are the immediate vicinities of drill holes which intersected zones of coincident sandstone alteration and anomalous uranium content proximal to significant graphitic basement faults. Up to four initial target areas will be evaluated during winter 2026.

 

Drilling plans at MLN will kick off after the Darby drilling is completed, and will comprise approximately 1,200 metres and will follow up summer 2025 results at the Cyclone trend where broad zones of structure and alteration were intersected over a two-kilometre strike length. Drilling will target a 1,200-metre gap in existing drilling where a lake prevents summer access. Drilling will also test a potential trend parallel to and approximately 100 metres south of Cyclone interpreted from intensely graphitic rocks and faulting intersected in the basement of MLN25-007.
