Canada-listed gold miner SSR Mining said late on Sunday that its environmental permit for a gold mine in eastern Turkey has been revoked.
The operations at the company's Copler mine will remain suspended until further notice, the company said.
The developments come after a landslide at the gold mine that left at least eight miners missing and sparked a more than 50% drop in its Toronto-listed shares.
Search and rescue operations to locate the nine missing workers at the mine are continuing, the company said.
The mine produced 56 768 oz of gold in the third-quarter of last year and is SSR's second-largest producing gold mine, operating since 2010.
