CSIRO gossan geochemistry and district scale-laterite geochemistry at the Archaean Golden Grove base- and precious-metal ore deposits, Yilgarn Craton, Western Australia. Carried out by Ray Smith and colleagues, 1977 - 2007.

The study is located on the Yalgoo, 1:250 000 map sheet, SH50-2. Gossan Hill, named because of the gossan discoveries there in 1971, is located at latitude -28.774, longitude 116.9633. This legacy geological and multi-element geochemical data underlies several geoscience journal publications, listed in an attached file as part of this data entry. The data arises from 597 regolith samples including 104 gossan samples analysed in 1977 to 1985. Data includes re-analysis in 1993 of 341 samples as well as analyses of some additional samples (total 436 samples) spread from Gossan Hill to the Scuddles Deposit which was discovered in 1979.
The original sampling is referred to as the "Old Golden Grove geochemistry", the follow-up data as the "North Golden Grove geochemistry". The original analyses are carried over to the new data file for the North Golden Grove geochemistry.
The sampling and data were to (a) enable gossan identification, (b) test for geochemical signal in lateritic residuum and colluvium about the Gossan Hill location, and (c), with (b) being successful, to carry out trial laterite geochemistry as an exploration procedure over some 25 km of strike length of the prospective sequence. At the time, this was a novel approach to mineral exploration, believed to be the first of its kind.
