07:18 AM EDT, 09/22/2025 (MT Newswires) -- Leading Edge Materials ( LEMIF ) earlier Monday said its Swedish unit Greenna Mineral AB (GMAB) submitted supplementary information in respect of its application for an Exploitation Concession, a 25-year mining lease, for the Norra Karr Heavy Rare Earth Elements Project (HREE).

The company said the supplements were prepared in response to requests by the County Administrative Boards of Jonkoping and Ostergotland and statements from various regional stakeholders for additional information on the possible environmental impacts of the project. It believes that all questions and concerns raised during this permitting stage were addressed.

"We are actively engaging with local communities to highlight how significantly the current Norra Karr project differs from previous plans," Leading Edge Materials ( LEMIF ) chief executive Kurt Budge said.

"The new approach features a 65% smaller operational footprint, streamlined operations focused solely on extraction and mineral processing, enhanced commercial potential through valuable HREE and industrial mineral products, and substantially reduced environmental impact."

Shares of the company closed down 2.2% to $0.225 on the TSX Venture Exchange Friday.
