Denison Mines (TSX: DML and NYSE American: DNN) was at last look up 1.3% and near its 52-week high in US premarket trading on Monday as it filed a final environmental impact statement for the Wheeler River Uranium project with the Canadian Nuclear Safety Commission.

This come after it completed the technical review phase of the federal environmental assessment approval process.

According to a statement, the final EIS reflects "many years of considerable effort" following the initiation of the EA process in 2019 and proactively incorporates feedback received from multiple interested parties, including Indigenous nations and the CNSC's Federal Indigenous Review Team.

"The completion of the federal technical review and submission of the final EIS represents a notable milestone for Denison in our efforts to obtain regulatory approval for Wheeler River," Denison President and CEO David Cates said in a statement. "Owing, in large part, to the use of the In-Situ Recovery ("ISR") mining method, the EIS evidences that the project can be constructed, operated, and decommissioned while achieving a superior standard of environmental sustainability when compared to conventional uranium mining operations."

DML edged down $0.02 to $3.32 on the TSX, Friday, but remains near 52 week highs.
