AngloGold Ashanti has awarded a mining services contract worth about $500m to Barminco for its Sunrise Dam project, located 56km south of Laverton, Western Australia.
Under the five-year contract, Barminco will provide all underground mine operating activities including development and production.
At Sunrise Dam, gold ore is structurally and lithologically controlled within gently dipping high strain shear zones and steeply dipping brittle-ductile low strain shears zones.
Host rocks include andesitic volcanic rocks, volcanogenic sediments and magnetic shales.
Barminco CEO Neil Warburton said AngloGold Ashanti's renewal of the contract was recognition of Barminco's ability to consistently deliver high safety and productivity.
"The longer-term renewal of this significant contract with such a high-calibre client demonstrates a partnership that has grown over many years, delivering key performance outcomes for AngloGold Ashanti and a high level of confidence in Barminco," Warburton said.
