Mining companies in Australia came to prominence as an important source of export income for the colonies on this developing island continent. In the 1840s, South Australia heralded the first discovery of silver and lead to immigration of miners and export of ore. The discovery of copper soon took over as the nation’s top export, but it was the discovery of gold in 1851, near Ophir in New South Wales, that triggered the real mining frenzy
With about 350 operational mines, Australia produces 19 minerals including iron ore, bauxite (aluminium ore), lithium, lead, gold, diamond, zinc and uranium. Australia also produces significant amounts of black coal, nickel, manganese, silver, copper, antimony, cobalt and tin
The country currently leads the global mining sector, with nearly 40% of the market value share. According to the Minerals Council of Australia, mining impacts a minuscule part of this vast country’s land surface with huge scope for more operations
Topping this list of Australia’s mining companies is Melbourne-headquartered Anglo-Australian BHP Group, which specialises in the mining of petroleum and metals. Previously called BHP Billiton (a 2001 joint venture of Billiton — established in 1860 and Broken Hill Proprietary Company — established in 1885), this behemoth of the mining industry has mineral and oil and gas operations in Australia and both American continents. Armed with a workforce of about 62,000 worldwide, BHP Group generates revenues of more than $43 billion annually
Chief assets of BHP include a 57.5% stake in the Escondida copper mine in Chile’s Atacama Desert, along with ownership of major copper producer and one of the world’s largest orebodies, the Olympic Dam mine of Australia. This mining sector powerhouse boasts a colossal market cap of almost AU$170bn on the Australian Stock Exchange (ASE)
Diversified mining titan Rio Tinto ranks second on this list, along with being the second biggest mining company in the world behind BHP. Established in Spain, in 1873, the mining company now has its headquarters in Melbourne. With a workforce of about 47,000 spanning six continents and 35 countries, Rio Tinto has generated revenues to the tune of $38bn annually
