Thiess says it has been named preferred mining services provider for the Hillside copper-gold project on the Yorke Peninsula in South Australia.

Rex Minerals Ltd, owner of the project, has notified Thiess of its intention to enter into exclusive negotiations to finalise the terms of a five-year mining contract.

Subject to a contract being concluded, which Rex says is expected to occur by the end of the year, Thiess is expected to deliver mining services and operate and maintain mining fleets to support the greenfield copper operation.

Rex says it plans to mine the open-pit orebody in five stages with selective ore mining and stockpiling. Average total rock movement from the open pit is expected to be 60 Mt/y.

Thiess, Rex says, has shown genuine willingness to join the company and drive down project costs, including:

• Developing appropriate and flexible mining equipment options;
• The early integration of personnel to assist with the project planning including optimal mine infrastructure area (MIA) layouts, and;
• Use of Thiess’ proven HSE systems to further de-risk the project with a planned commencement in early 2023.

Thiess Executive Chair & CEO, Michael Wright, said: “We are delighted to be taking the next steps towards a partnership with Rex Minerals on the Hillside project. In line with our strategy to diversify our commodities and services, we are positioning Thiess at the forefront of sustainable mining. We share Rex Minerals’ belief in the significant contribution that metals make to a renewable future, and to the local communities and broader economy.”

Thiess Executive General Manager for Australia West, Spencer Jose, said: “We look forward to collaborating with Rex Minerals, the Narungga People, local businesses and the community to deliver safe, strong operational performance and sustainable outcomes for all of our people and stakeholders.”

Mining services are expected to commence in July 2023, subject to finalisation of contracts.
