[{"type":"text","content":" TORONTO, Nov. 6, 2023 /CNW/ - Denison Mines Corp. (\"Denison\" or the \"Company\") (TSX: DML) (NYSE American: DNN) is pleased to announce the successful completion of the inaugural In-Situ Recovery (\"ISR\") field test program within the Tthe Heldeth Túé uranium deposit (\"THT\") at the Company's 67.41% owned Waterbury Lake Uranium Project (\"Waterbury\"), which is located in northern Saskatchewan, Canada and is situated in close proximity to key regional infrastructure, including roads, the provincial power grid, and Denison's 22.5%-owned McClean Lake mill (see Figure 1). The THT ISR field test involved the installation of an 8-well ISR test pattern (\"Test Pattern\") designed to collect an extensive database of hydrogeological data, and the program successfully achieved each of its planned objectives, including: Confirmed Hydraulic Conductivity: Pump and injection tests were successfully completed within the Test Pattern, validating hydraulic connectivity in 100% of the test wells within the ore zone, and achieving hydraulic conductivity values (a measure of permeability) consistent with the 2020 Preliminary Economic Assessment (\"PEA\") for the project. Sufficient permeability within the ore zone is a key criteria for the successful deployment of the ISR mining method. Established 10-hour Breakthrough Time with Ion Tracer Test: A subsequent tracer test significantly increased the confidence in the initial hydrogeological evaluations (pump and injection tests) within the Test Pattern. The tracer test demonstrated Denison's ability to maintain hydraulic control of injected solutions and achieve breakthrough times consistent with expectations. Demonstrated the Effectiveness of Permeability Enhancement: One method of permeability enhancement was successfully deployed from multiple wells demonstrating the suitability of the method to the THT deposit. Efficiency of permeability enhancement was verified by comparison of pre- and post-permeability enhancement hydraulic testing. David Cates, Denison's President and Chief Executive Officer, commented \"Our recently completed ISR de-risking efforts at THT demonstrate the competitive advantage of our in-house Saskatoon-based techni...
