Tennant Creek – Mount Isa IOCG mineral potential assessment
One of the aims of the Exploring for the Future program is to promote the discovery of new mineral deposits in undercover frontiers. Iron oxide–copper–gold mineral systems are a desirable candidate for undercover exploration, because of their potential to generate large deposits with extensive alteration footprints. This mineral potential assessment uses the mineral systems concept: developing mappable proxies of required theoretical criteria, combined to demonstrate where conditions favourable for mineral deposit formation are spatially coincident. This assessment uses a 2D geographical information system workflow to map the favourability of the key mineral system components. Two outputs were created: a comprehensive assessment, using all available spatial data; and a coverage assessment, which is constrained to data that have no reliance on outcrop. The results of these assessment outputs were validated with spatial statistics, demonstrating how the assessment can predict the presence of known ore deposits. Both assessment outputs present new areas of interest with prospectivity in under-explored regions of undercover northern Australia. The intended aims are already being realised, as this tool has aided area selection for pre-competitive stratigraphic drilling as part of the MinEx CRC National Drilling Initiative.

- Purpose
-
This study was conducted under the Exploring for the Future initiative, as a part of uncovering the mineral potential of Northern Australia. The data for this assessment have been sourced from geological, geophysical and geochemical datasets. The input datasets produced and used in this assessment were sourced from Geoscience Australia databases and are publicly available via the Geoscience Australia website. Derivative products of the input datasets were developed for the assessment (e.g. buffered zones). Decisions concerning the development of these derivatives, such as the selection of buffer distances and assignment of cut-off values, were made subjectively based on the scientific judgement of the assessment team. Further information regarding the datasets used, data processing steps, criteria weightings and scientific rationale can be found in the accompanying data release ( https://doi.org/10.1016/j.oregeorev.2019.103011). Scripts to automate GIS workflow, are based off scripts by Coghlan (2015).Coghlan, R.A., 2015. Nickel-Mineral-Potential-Modelling (Version 1.0) [Source Code].
