Jacobs has been awarded a contract by Newcrest Mining to provide underground materials handling services as part of the expansion feasibility study at Cadia, one of Australia’s largest gold mining operations.

This contract award builds on Jacobs mining and minerals business’ long history of working with Newcrest across the company’s Cadia Valley operations in New South Wales, Jacobs said.

Jacobs Mining, Minerals and Technology Senior Vice President, Andrew Berryman, said: “During the previous study phase, our mining and minerals experts helped identify a low capital intensity solution as part of an integrated team. By embracing an owners’ mindset and applying our experience in underground mining, materials handling and expansion projects, our integrated approach has the potential to deliver an impressive return on capital for Newcrest.”

The prefeasibility study on an expansion at Cadia envisaged the plant and underground materials handling upgrade costing A$58 million ($41 million). This was part of a bigger A$598 million project to incrementally increase throughput from the base case of 30 Mt/y to 33 Mt/y. Newcrest said that options to further debottleneck to 35 Mt/y would be assessed during the feasibility study.
