[{"type":"text","content":" TORONTO, Oct. 28, 2021 /CNW/ - Denison Mines Corp. (\"Denison\" or the \"Company\") (TSX: DML) (NYSE American: DNN) is pleased to announce the initial results of a highly successful In-Situ Recovery (\"ISR\") field test program (\"2021 ISR Field Test\") completed within the commercial-scale ISR test pattern installed in the Phase 1 area of the high-grade Phoenix uranium deposit (\"Phoenix\") at the Company's 95% owned Wheeler River Uranium Project (\"Wheeler River\" or the \"Project\") in northern Saskatchewan. Achieved the commercial-scale production flowrate assumed in the Pre-Feasibility Study (\"PFS\") prepared for the Project in 2018. Demonstrated hydraulic control of injected solution during ion tracer test – reporting no elevated values of the tracer element in the monitoring wells surrounding the commercial-scale test pattern. Established breakthrough times between injection and recovery wells, spaced 5 to 10 meters apart, that are consistent with previous 'Proof of Concept' hydrogeological modelling conducted by Petrotek Corporation (\"Petrotek\"). Completed 'clean-up phase' following tracer test demonstrating ability to remediate the test pattern – reducing tracer concentrations to as low as 4% of peak test levels within eight days of remediation. David Cates, Denison's President & CEO, commented, \"We are pleased to have safely and successfully completed another significant ISR field program at Phoenix. Our evaluation team and field staff have worked diligently over an eight-month period to expertly carry out a complex project execution plan that has delivered the data and results necessary for our Company to continue our industry-leading efforts to further de-risk the application of the ISR mining method in the Athabasca Basin region. While our previous test work has provided considerable support for the use of ISR at Phoenix, the achievement of the targeted flowrate from the PFS in a commercial-scale well pattern located within Phase 1 of Phoenix, and the tangible demonstration of our ability to control fluid flows during the tracer test, together mark another highly significant de-risking milestone for the Project. With the field test completed and the Company well capitalized, our technical team is moving full-steam ahead with the development of our field plans for 2022 while also suppor...
