Geology
The Mt Rawdon gold deposit is a massive, volcaniclastic hosted, low grade gold deposit that exhibits excellent characteristics conducive to low cost mining and treatment. The surface extent of mineralisation greater than 0.7g/t gold formed an ovoid zone 400 metres x 280 metres in diameter on the southern flanks of the original Mt Rawdon. The gold mineralisation is closely associated with fine disseminated pyrite within the host rocks as well as more discrete sulphide veinlets. Gold grade generally increases as pyrite alteration and sulphide veining increases. The principal host volcaniclastic rocks dip moderately to the southwest, as does the orebody.

Mining
Mine production is derived from a single open pit, utilising conventional drill and blast, load and haul methodologies. The mine successfully transitioned to owner-miner in the September quarter 2014 with better than expected productivity and operating costs achieved. The operation is one of our most reliable mines, that has produced more than 1.5 million ounces of gold since first production in 2001.

Processing
The processing plant consists of primary and secondary crushing, SAG and ball milling, followed by conventional cyanidation leaching. In July 2014, a significant milestone was reached with the 40th tonne of gold (approximately 1.41Moz) poured since production commenced in 2001.
