The company stated that the approval was a part of purchase agreement inked with AREVA’s subsidiary COGEMA Resources to acquire all the outstanding shares of Pathfinder.

Ur-Energy CEO Wayne Heili said: "The completion of the Pathfinder transaction remains an integral element of Ur-Energy’s U.S. based in-situ uranium recovery strategy. We look forward to closing the acquisition in the near future."

Besides Shirley Basin, NRC has also approved the license transfer for the Pathfinder Lucky Mc tailing site to COGEMA.

Ur-Energy would take no obligations for the tailing site, which is fully reclaimed and is being transferred to the US Department of Energy, the company said in the statement.

With these approvals, Ur-Energy and COGEMA are seeking remaining governmental approvals, alongside additional customary closing conditions to execute the acquisition agreement, due to be completed in the third quarter this year.
