The proposed decision will allow the company to build a viable business, the company said.
National broadcaster ABC quoted BHP Billiton as saying: "Over the past few months, Olympic Dam has been focused on identifying opportunities to safely reduce costs in order to build a strong, viable businesss.
"As a result, a number of positions will be made redundant, however the impact of these redundancies will be minimized through some redeployments opportunities."
The net figure for workforce redundancies has not been revealed and the process is expected to be completed later this year.
The company plans to accelerate Olympic Dam operations in middle of this year and create 100 new jobs. The ore body is said to contain uranium oxide, copper, gold and silver.
