Modelled on the Soviet system, the Chinese industry is instead divided by function, with geological bureaux given the task of finding a deposit and turning it over to a state-owned mining company for development. Economic reforms have added small privately owned miners to the mix and made it possible for the geological bureaux to develop some mines themselves.
As a result of that system, most of China’s large mining companies know a lot about mine engineering and little about geology, and so prefer to invest in overseas projects that are already developed and close to producing.

The Ridgeway underground mine cave is located in the mineral-rich Cadia Valley province in central New South Wales. A gold and copper mine, it is 100% owned by Australia's Newcrest Mining, and is one of three operations owned by the company in the province. The others are Cadia East and Cadia Hill, the largest of the three. "The Ridgeway underground mine cave is located in the mineral-rich Cadia Valley province."Ridgeway is in the process of transitioning from the sub-level cave to a block cave beneath the existing mine. In 2007 the Newcrest board approved development of the Ridgeway Deeps block cave. It will be the first natural caving operation to be developed by Newcrest and will be the deepest block cave in Australia. The company says it is spending A$525m to develop it. The mineral resource at Ridgeway Deeps was re-estimated following a geological reinterpretation which yielded an increased resource of 20 million tons containing 0.5 million ounces of gold, and 0.05 million tons of copper.
