Wilgie Mia
Western Australia, Australia
Wilgie Mia, also called Thuwarri Thaa (‘red ochre hole’) is an ochre mine in the Weld Range of Western Australia. It has been in use for 27,000-40,000 years, during which an estimated 14,000 cubic metres (490, 000 cu ft) of ochre and rock was mined. This has led to suggestions that Wilgie Mia is the world's oldest continuing mining operation.
