It comes as the high tech metals group attracts increasing interest from European investors.
It has filed preliminary documents with Nasdaq Stockholm AB for a proposed dual listing, it revealed on Wednesday, and, if it is successful, hopes the process will be completed before the end of the year.
"Listing of Leading Edge Materials on Nasdaq First North Stockholm is a natural next step as we build our business to serve the specialty materials needs of the European Union," said Blair Way, Leading Edge's president and chief executive.
The group said it had been "encouraged" by a steady increase in interest from European investors over the past year.
"This positive trend matches the growing European awareness of the rapid global shift to electric mobility, and the need for secure critical raw material supply chains if the European automotive industry is to play a leading role," the company said.
Nasdaq Stockholm is a very active market, with 56 new listings during the first half of this year.
The Nordic region boasts the largest retail presence in the world per capita, with small private investors and professional investors taking an active role in the market
Last month, Leading Edge reported positive results from testing of material from its Norra Karr heavy REE (rare earth element) deposit in Sweden, including a development process it described as a potential "game -changer".
The research was completed under the European Commission-financed EURARE project and made significant technical milestones.
Produced was around 25kg of mixed REE carbonate from concentrate, using a new hydrometallurgical method, LEM said.
Significantly, this delivered high REE recovery with a substantial reduction in water used and recovered additional high-value metals hafnium and zirconium.
