Broken Hill’s Perilya’s Southern Operations will cut between 90 and 100 positions from the historic silver, lead and zinc mine.
The mine owner announced yesterday that 20 per cent of the 460 strong workforce would be cut in response to low metal prices.
Earlier this month it was presumed 120 positions would go from the Broken Hill mine.
Perilya managing director Paul Arndt said 40 workers had accepted voluntary redundancies, with 34 accepted.
Workers were informed of the cutbacks by two different letters yesterday.
"One is indicating that their employment will be continuing and the other is an indication that your position will be made redundant," Arndt said.
"With those people that have obtained that second letter, some of those will be asked to take alternative roles."
Local CFMEU vice-president Greg Braes said employees who accepted alternative positions with Perilya would risk having to accept pay cuts in the new roles.
