In the early 1970s, Geo chemists contracted by Western Mining Corporation conducted geochemical logging of the centre or core, which means measuring, depicting and where conceivable recognizing the rock units from the top to the lowest part of the hole. Through this Western Mining Corporation related a large portion of the major rocks with lime stones, sandstones and shales of in the Olympic Dam that were extremely natural based on numerous field excursions in Southern Australia. Likewise, they took a chip test each 15centimetres along the core named RD1. The samples prepared over every two-meter interim were sacked together and sent to Western Mining’s geochemical research centers in Ballarat for testing for the terrifically-paramount hints of copper and other deposits.
By using their knowledge, Geochemists built some innovative methods amalgamated with best scientific techniques to come up with geochemical sampling idea that led to the discovery of ore-body at the Olympic Dam. With the assistance of Bureau of Mineral Resources, a colorimetric test for copper, zinc and lead was produced to utilize in the field of Olympic Dam. It was an unrefined however compelling approach to distinguish peculiar measures of copper on the field, with the trust of tracing them upstream to their source. Geochemists grasped every chance to utilize the best science techniques and imaginative considering actions, including new geochemical study strategies, and aggressive investigation for conceivable Australian analogies of copper deposits in the US as well as Africa.
Later, in the treatment procedure anticipated for Olympic Dam that led to the discovery of deposits, uranium oxide was drained from the concentrate before it was sent to the purifying stage. In principle, this could have made the concentrate suitable for sending to off-sites for custom refining and smelting. Trial handling and processing of the ore in a pilot plant at Olympic Dam uncovered the drained concentrate still contained remaining uranium and uranium rot products. Shipping this material to custom smelters was not conceivable on the grounds as it could have debased copper items purified for different organizations.
