PERTH (miningweekly.com) - Gold miner Northern Star Resources has awarded ASX-listed GR Engineering Services a A$101-million engineering, procurement and construction (EPC) contract for the Thunderbox six-million-tonne-a-year expansion project, in Western Australia.
The expansion project will increase the Thunderbox mine’s hard rock processing capacity from the current three-million tonnes a year to six-million tonnes a year, and will decrease processing costs by around A$5/t, to around A$100/oz of gold.
The expansion project will cost an estimated A$180-million, and will see the installation of a new 18 MW mill and classification circuit, new leach tanks, elution and gold room upgrades, new tailing thickener and tailings pumping.
