RIO Tinto has awarded engineering firm Civmec with two contracts worth $A160 million for work at its $2.6 billion Amrun bauxite mine in Queensland. One contract is for the processing facility, while the other is for the part-supply of a stacker, reclaimer and shiploader. Rio said around 6,200 tonnes of steel would be required for the projects, which would be sourced from Port Kembla and Whyalla, and fabricated at Civmec’s Perth and Newcastle facilities.
