The first contract, which is worth around $100 million, involves the provision of refractory services for a period of eight years.

It includes gunning and casting and installation of refractory products and anchors. SRG will commence its work this month for a duration of eight years.

The second contract is a two-year extension of SRG Global’s engineered access services at Worsley Alumina, worth around $25 million. SRG Global will continue to provide these services until mid-2027.

SRG Global managing director David Macgeorge said these contracts were a terrific achievement for the company.

“… We are excited to be expanding our partnership with South32 to continue to deliver long-term value for their Worsley operations,” he said.

“This continues our focus on cross-selling our diverse capability to add value to key clients and our strategy of transitioning the earnings profile of the business to annuity style asset services contract.”

The Worsley Alumina operation is jointly owned by South32 (86 per cent), Japan Alumina Associates (10 per cent) and Sojitz Alumina (4 per cent).

It comprises the Boddington bauxite mine, an overland bauxite conveyor and the Worsley Alumina refinery.
