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 October 14th which announced the identification of multiple high priority follow up drill targets at the Darby Project.  Darby is a joint venture (JV) between Cosa and Denison Mines Corp. (TSX: DML) (NYSE American: DNN) and is located 10 kilometres west of Cameco’s Cigar Lake Mine in the eastern Athabasca Basin, Saskatchewan. Cosa is the project operator and holds a 70% interest with Denison holding a 30% interest.

 

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

 

The identification of highly prospective drill ready targets 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 in June of this year. Their work confirmed desktop interpretations and generated immediate follow up targets.

 

When the team at Cosa reviewed the historic work by prior operators, it interpreted that of 31 drill holes on the Property targeting conductive anomalies only 13 (42%) explained their target and only six (19%) were effective evaluations of the targeted area, leaving over 80% of the Projects’ 40 kilometres of conductive strike length untested. Multiple historical drill holes intersected features suggesting proximity to uranium mineralization – warranting direct follow-up drilling in the future.

 

Andy mentioned that with a more experienced scientific understanding and framework today, and by applying the same target identification approach that led them to discover the Hurricane Deposit in 2018, that they are very encouraged by the historical data and drill core. Coincident alteration, illite, and chlorite plus broad zones of anomalous uranium in the lower sandstone are strong indicators of a uranium bearing system in the eastern Athabasca including at the nearby Cigar Lake mine.

 

The Company will begin the approaching 2026 drilling season with highly prospective follow up targets at both Darby and Murphy Lake North. Keith mentioned that they are looking forward to finalizing drilling plans and budgets their joint venture partner and largest shareholder, Denison Mines, and discussed the benefit of their continued guidance and support on these exploration initiatives.
