Aim-listed Caledonia Mining has applied for a voluntary delisting from the TSX, effective June 19.
Its shares will continue to trade on the NYSE American and the Aim.
Caledonia says that, since its shares were listed on the NYSE American in 2017, trading on that market has become dominant and it now provides the most liquid market for the company's shares.
It believes the financial and administrative costs of maintaining a listing on the TSX are no longer justified.
