Denison Mines Corp. (NYSEAMERICAN:DNN) is one of the best uranium stocks to buy according to Wall Street analysts. On May 6, Cosa Resources Corp. released winter 2026 drilling results from the Darby uranium project, which it co-owns with Denison Mines Corp. (NYSEAMERICAN:DNN). The project is a 70/30 joint venture between Cosa and Denison, and Cosa is the operator. It is located just 10 kilometers west of Cameco Corporation’s Cigar Lake Mine, which is one of the world’s largest high-grade uranium mines.
According to the drilling results, the winter program drilled three holes targeting three distinct geological trends, that is Charlie, Gamma, and Delta. At the Charlie Trend, drill hole DB26-39A returned strongly anomalous uranium concentrations in the sandstone, which averaged 5.6 parts per million (ppm) over 103.5 meters. The hole also intercepted a thin interval of actual uranium mineralization grading 0.04% U3O8 over 0.5 meters. The company said this is the second such interception at Charlie, and that it confirms the trend holds genuine exploration potential.
At the Gamma Trend, the project drilled a hole roughly 150 meters across, and it was characterized by graphitic basement faulting, zones of hydrothermal alteration, and significant unconformity relief. These features form a geological setting geologists consider highly favorable for uranium deposit formation, the company noted.
Cosa said results from the Delta Trend were less conclusive because the single drill hole did not return significant findings. However, the company added, geochemical assays are still pending and several kilometers of prospective strike length at site are still untested.
Denison Mines Corp. (NYSEAMERICAN:DNN) is a uranium exploration and development company. Its flagship asset is the Wheeler River Uranium Project, which includes the high-grade Phoenix deposit planned for development using in-situ recovery methods.
