chalcocite zone. Gold and silver are more commonly associated with chalcopyrite mineralisation. The gold ore also occurs in discrete zones within the granite-rich or haematite-rich breccias. These zones may have high concentrations of gold, particularly around the margins of the haematite-quartz breccias that form the core of the ore body.

Gold has remarkable chemical and physical properties which make it an incredibly useful material despite its high price. Australia's gold exports generated $24.4 billion in revenue in 2022-23. Gold not only spurred Australia's first mining boom, it triggered the gold rushes of the late 19th century.

From the electronic scrap, gold with 99.9% purity is possible to recover[17], [18]. In this research for the primary production, the underground mining process of gold is considered. The primary gold materials are then used for electronics industries which are further recovered through recycling in secondary production.
