Southern Cross Electrical Engineering has been awarded two contracts worth $69 million in total for electrical infrastructure at the Tropicana gold project and Rio's Tinto's Yandi Sustaining Project.
Work will commence immediately at the Tropicana gold project and is due to conclude in May, next year.
The Tropicana gold project is a joint venture between AngloGold Ashanti and Independence Group NL.
"SCEE has a very long and successful history of working on gold plants in remote locations and this award allows us to continue to build on the experience gained over many years," SCEE managing director Simon High said..
"We look forward to continuing to work with AngloGold Ashanti Australia and the EPCM contractor, Lycopodium, in delivery of this very significant project."
The remote greenfield project is 330km east-north-east of Kalgoorlie and is expected to produce an average of 330,000-350,000 oz of gold a year over the life of the mine.
The project development required considerable supporting infrastructure including a new 11kv overhead powerline, SCEE said.
The powerline installation would be built by its specialist infrastructure business, SCEE Infrastructure.
SCEE's overhead powerline construction business, K.J. Johnson & Co Ltd, has been awarded a $29 million contract to design, supply and build overhead powerlines at Rio's Yandi Sustaining Project in the central Pilbara, with a forecast completion date in January, 2014.
Shares in SCEE were up one cent, 0.9 per cent, to $1.16 at 11.34am.
