Ausenco has been awarded the Engineering, Procurement and Construction Management (EPCM) contract for the Hillside Project (“Hillside”) on behalf of Rex Minerals Pty Ltd (“Rex Minerals”), an Australian minerals exploration and development company.
Located on the Yorke Peninsula in South Australia, approximately 150 km west of Adelaide, the Hillside project is one of the largest undeveloped copper and gold projects in Australia, containing a Mineral Resource of 1.9 Mt of copper and 1.5 Moz of gold. Stage one of the project received government approval in 2020 for a 13-year mine life. 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.
Ausenco is a global leader in the design and construction of copper operations. In the last five years, we have designed and built one in three new copper concentrators globally, most recently 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 8 Mt/y plant and associated plant infrastructure.
Reuben Joseph, President – APAC/Africa at Ausenco, said, “Hillside represents a significant copper development, and we’re proud to bring our expertise in concentrator design and delivery. Our team is committed to building a high‑performance plant that delivers efficiency, operability and long‑term reliability.”
