The open-pit preferred tenderer is Macmahon and the EPC process plant preferred tenderer is GR Engineering. “Both of these companies have exceptional track records in the gold mining industry,” Calidus Managing Director Dave Reeves said. The initial construction activities include a 7-kilometer (km)-long access road to a 240-room village and process plant, the installation of communications by Telstra and drilling dewatering wells. Awarding the preferred contractors also allows Calidus to facilitate Front End Engineering and Design (FEED) and place orders for the long lead items, the company said.
