According to Mining News Pro - “A re-start of open pit mining operations won’t occur until the Company is certain that the search and rescue efforts will not be affected and a revised waste dumping plan has been completed,” the company said in a statement.

The miner said on Sunday that two of its employees had gone missing after a “significant rock movement” at a waste rock dump.

The miner also said it was assessing alternative waste rock dumping plans. Shares of the company closed down nearly 11%.
