Successful completion of the neutralizationDenison Mines Corporation announced the successful completion of the neutralization phase of the Phoenix in-situ recovery Feasibility Field Test at the Company's 95% owned Wheeler River 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.
