Mineral Prospectivity Analysis of the Wagga–Omeo Belt in NSW by David Robson, Geological Survey of NSW

The Geological Survey of New South Wales will release its new Riverina Gravity data at this meeting. DVD copies of the data including a suite of images (ECW, jpg, tiff formats) and reports on the area will be on sale at the standard $110 charge. The data collected on 2km and 1km grids, covers the Cootamundra, Wagga Wagga and Tallangatta (NSW part) 1:250 000 scale sheets. It provides new information along the prospective Gilmore Fault Zone and extends the Wagga Tin Belt into areas of cover.
The Wagga–Omeo Belt in NSW has been a significant tin, gold, silver and copper producer. An analysis of the mineral prospectivity of the region has been undertaken by estimating the number of undiscovered deposits, estimating mineral endowment, and by predicting the likely locations of undiscovered deposits. Both spatial prediction (mineral prospectivity mapping) and quantitative resource assessment were undertaken with a focus on tin mineralisation in the region. Results from the analysis of the spatial pattern of known deposits using the weights of evidence method, indicate likely locations of undiscovered tin deposits. David will also discuss the results of the recent hydrogeochemical study and the reprocessing of the radiometric data.
