Ausenco has been awarded the EPCM contract for Rex Minerals Hillside project in South Australia, about 150 km west of Adelaide.
Located on the Yorke Peninsula, the Hillside project is one of the largest undeveloped copper and gold projects in Australia, containing a mineral resource of 1.9mt of copper and 1.5moz of gold.

Stage one of the project received government approval in 2020 for a 13-year mine life and, since then, Ausenco has supported Rex Minerals through a series of studies and early-stage activities, including a definition phase study, capex refresh and enabling works.
In the last five years, Ausenco has designed and built one in three new copper concentrators globally, most recently at the Mantoverde copper project in Chile.
Building on its longstanding partnership with Rex Minerals, Ausenco will now deliver detailed engineering through to commissioning of the 8mtpa plant and associated plant infrastructure.
Ausenco APAC and Africa president Reuben Joseph says Hillside represents a significant copper development, and the company is proud to bring its expertise in concentrator design and delivery.
“Our team is committed to building a high-performance plant that delivers efficiency, operability and long-term reliability,” he said.
