Macmahon wins underground contract

Macmahon has won a $110 million underground construction contract at the CSA mine.

Work at the Cobar based copper gold mine in NSW will see Macmahon undertake the project works as a turnkey contract.

This includes all engineering design, fabrication, procurement, construction, and management of the extension and upgrade of the CSA No.1 Shaft.

Scope of the work includes the extension of the existing shaft from 1050 metres to 1550 metres including ground support and concrete lining; equipping the shaft for hoisting to the surface’ construction of a new head frame and installation of a tower mounted friction winder; and the construction of a new underground materials handling system including crusher, ore bins, conveyors and a loading station.

Upon completion, the new underground materials handling and shaft hoisting system will have a capacity of 1.6 million tonnes per annum from a depth of 1500 metres.

The project will be delivered by the Engineering Division, which was previously part of the Underground Division.
