[{"type":"text","content":" TORONTO, Dec. 12, 2022 /CNW/ - Denison Mines Corp. (\"Denison\" or the \"Company\") (TSX: DML) (NYSE American: DNN) is pleased to announce the successful completion of the neutralization phase of the Phoenix in-situ recovery (\"ISR\") Feasibility Field Test (\"FFT\") at the Company's 95% owned Wheeler River project (\"Wheeler River\" or the \"Project\"). Sampling of monitoring wells around the FFT site has confirmed the successful restoration of the Leaching Zone (defined below) to environmentally acceptable pH conditions, as outlined in the applicable regulatory approvals for the FFT. The neutralization phase was initiated in mid-October 2022, following the highly successful completion of the leaching phase of the FFT (see news releases dated October 17, 2022 and November 22, 2022), and was designed to confirm certain environmental assessment assumptions and verify the efficiency and effectiveness of the neutralization process planned for ISR mining at Phoenix. David Cates, Denison's President & CEO, commented, \"The completion of the neutralization phase of the FFT marks the end of our 2022 evaluation field activities at Wheeler River. During the year we successfully constructed and commissioned the FFT facilities, and carried out both the leaching and neutralization phases of the FFT. Our recovery of uranium bearing solution (\"UBS\") with the use of the ISR mining method is a first in the history of the Athabasca Basin region, and now we have achieved another landmark accomplishment with the restoration of the test area to environmentally acceptable pH conditions. The work was done on schedule and without any recordable safety incidents – which is a testament to the hard work and professionalism of our dedicated Saskatchewan-based staff of geoscientists, engineers, metallurgists, process operators, well field operators, and contractors.\" Kevin Himbeault, Denison's Vice President of Plant Operations & Regulatory Affairs, added, \"The Company embarked on the FFT to confirm the practical application of the ISR mining method within the high-grade Phoenix uranium deposit. The results from the leaching and neutrali...
