Overview
Olympic Dam is one of the world's most significant deposits of copper, gold, and uranium. It is owned and operated by BHP and is part of the company's Copper South Australia province. The operation consists of an underground mine and a fully integrated metallurgical complex, including an onsite smelter and refinery. Macmahon Holdings is a contractor that has provided underground mine development services at the site.
Production
Production overview - 2023: copper 212000 t, gold 186000 oz.
Processing
The mine utilises an underground mining method called sublevel open stoping. Ore is hauled to the surface for processing via an automated train system and trucks. The fully integrated metallurgical complex features a grinding and concentrating circuit, a hydrometallurgical plant with solvent extraction for copper and uranium, a copper smelter, a copper refinery, and a recovery circuit for precious metals.
Expansion
In the 2023 financial year, Olympic Dam achieved record annual production for copper, gold, and silver. Following BHP's acquisition of OZ Minerals, Olympic Dam is now part of the newly created Copper South Australia province, which also includes the Prominent Hill and Carrapateena operations. BHP is conducting significant exploration drilling beneath the known Olympic Dam ore body, referred to as OD Deeps, which has identified extensive copper mineralisation.

Operating
Gold
End year
2032
Workforce
Nearly 300 employees and contractors
Overview
Located approximately 50 kilometres southwest of Dubbo in the Central West region of New South Wales, Australia. The operation transitioned to being fully underground in 2023 and is currently active, with operating plans extending beyond 2030. Initial development was based on four gold deposits: Wyoming One, Wyoming Three, Caloma, and Caloma Two. Mining currently occurs underground on the Wyoming One, Caloma One, Caloma Two, and Roswell deposits.
Production
Production for the 2025 financial year was 70,120 ounces of gold. Production guidance for FY2025 was between 70,000 and 80,000 ounces. The five-year plan aims to increase production to above 100,000 ounces of gold per year from about 2027.
Processing
The processing plant has a design capacity of 1 million tonnes per annum (Mtpa). The processing method involves a two-stage crushing and grinding circuit, with gold recovery through gravity and carbon-in-leach (CIL) processes. A flotation and fine grind circuit was commissioned in December 2024, and a paste plant was commissioned in January 2025.
Equipment
One Sandvik DL432i production drill, four Epiroc MT65 trucks (65-tonne load capacity), three Cat 2900 loaders, a Cat 140M Grader, a new Development Jumbo drill, four Volvo ITs (integrated tool carriers), two Sandvik DD422i dual control jumbos, and a Sandvik DL422i longhole drill.
Expansion
The Tomingley Gold Extension Project (TGEP) is extending operations to the south to include the Roswell and San Antonio deposits. Plans to expand the processing rate to 1.75Mtpa.
