Two men have been killed after they fell about 20 metres down a shaft at the Mount Lyell copper mine at Queenstown on Tasmania's west coast.
The local men, aged 25 and 45, were maintenance workers for Copper Mines of Tasmania.
One of them is believed to have been killed instantly, while the other died on the way to hospital.
"Our deepest sympathies are with the families of the two workers, their immediate work mates and also our other site employees who will be saddened by this tragic accident," mine manager Scot Clyde said in a statement.
Tasmanian Premier Lara Giddings sent her condolences to the family, friends and colleagues of the two men.
Police and Workplace Standards are investigating and the coroner is on the scene.
The cause of the accident is not yet known and the mine will remain closed until tomorrow.
