The CSA Mine is located 11 kilometres north-west of Cobar, central western New South Wales. At 1.9 kilometres deep, it is one of Australia’s deepest underground mines and is Australia’s highest-grade copper mine.

Harmony is the largest gold producer by volume in South Africa and is a significant operator of gold tailings retreatment facilities. CSA Mine has recently joined Harmony Australasia, marking the beginning of an exciting new chapter. The acquisition underpins Harmony’s strategy to expand its Australasian footprint and establish a strong, diversified copper portfolio, complemented by the Eva Copper Mine Project in Queensland, currently under construction, and set to become the state’s largest open‑pit copper mine upon commissioning. In Papua New Guinea, Harmony owns and operates the Hidden Valley mine and owns 50% of the Tier 1 Wafi-Golpu copper-gold project. These assets are supported by the Harmony Australasia regional corporate office located in Milton, Brisbane.
