when did the expansion of the gold mines take place in the east rand
East Rand Mine East Rand Proprietary Mines (ERPM) is a 120-year-old underground gold mining operation on the Witwatersrand Basin at Boksburg, to the east of Johannesburg. The mine employed 2,740 people. It was the deepest mine in the world until 2008 at 3,585 metres depth, slightly more than the TauTona mine, also in South Africa, which was 3,581 metres at the time (in 2008 the TauTona mine completed a digging project that extended the depth of the mine by several hundred metres.)[1]
Australian gold rushes The first gold rush in Australia began in May 1851 after prospector Edward Hargraves claimed to have discovered payable gold near Orange, at a site he called Ophir.[3] Hargraves had been to the Californian goldfields and had learned new gold prospecting techniques such as panning and cradling. Hargraves was offered rewards by the Colony of New South Wales and the Colony of Victoria. Before the end of the year, the gold rush had spread to many other parts of the state where gold had been found, not just to the west, but also to the south and north of Sydney.[4]
