This report summarises exploration conducted by Western Areas between May 2021 and October 2021, under the ADI Agreement ADI: RD02/270-ED Sahara Prospect Model Test and Core Scanning. The discovery of magmatic Ni-Cu sulphide at Sahara in 2020, represented a major milestone in Western Areas Exploration strategy and confirmed the presence of significant, intrusive-hosted magmatic Ni-Cu sulphide in the Fowler Domain. (See ASX Release 24 July 2020). The proposal was to complete 1,400 m of Diamond drilling with two stratigraphic drillholes on a ‘type section’ located some 2 km south of the Sahara Discovery Zone to test for evidence of a Ni-Cu-PGE mineral system south of Sahara. In addition to drilling, the proposal included scanning of 1200 m of core using the Orexplore GeoCoreX10 instrument, using the patented AXM (Attenuation and X-ray fluorescence combined measurement) technique. Data is obtained from the entire core sample volume including 3D structures, geotechnical composition and mineralogy, texture, fabric and grain size, density, and attenuation. Orexplore Ltd were approached to complete experimental scanning of diamond drill core using integrated high-resolution X-ray tomography (XRT) and X-ray fluorescence (XRF) analysis. Exploratory data analysis aimed to provide insight into: • Distribution of lithological domains down hole for scanned drill holes. • Downhole sulphide modal estimates and definition of sulphide species present, with particular focus on Ni-bearing minerals, e.g., pentlandite • Structural analysis Two inclined diamond holes were drilled for a total length of 1428.8 m, with 131 downhole samples collected to for geochemical analysis. Drilling intersected the Sahara host gabbroic unit, with minor trace sulphides observed. Orexplore Cores Scanning commenced the scanning/digitisation of portions of cores from 5 Sahara drillholes, a total of 1493.03 m of core was scanned (sections of core from adjacent mineralised drillholes were included to capture data on the sulphide mineralisation to enhance the ability to interpret the dataset). This dataset will be used to perform exploratory data analysis including various regression analysis, structural analysis and data domain modelling. This data has been compared to field collected data with the aim of improving logging efficiencies and workflows. • Diamond drilling identified the southern extension of the Sahara intrusion and provided insight into the mineralization potential to the south of the discovery section. • Sulphide mineralization in both drillholes is limited to small zones of disseminated pyrite / pyrrhotite ± minor chalcopyrite / pentlandite. • Downhole electro-magnetics (DHEM) didn’t identify any follow up targets. • Interrogation of geochemical data identified a tholeiitic magma series and highlighted a fractionation trend from north to south. • Unsupervised algorithmic litho-domaining by Orexplore confirmed original geological logging. The approach works very well for sharp and well-defined contacts. In Summary, the ADI drilling has achieved the objectives of the proposal. It was determined that although the Sahara Intrusion increased in volume and width to the south, the area is less prospective for magmatic Ni-Cu mineralisation, and prospectivity generally increases to the north. The collection of data in a more distal location to the main zone of mineralisation has demonstrated a clear trend in the data, which combined with the Orexplore data has clearly demonstrated the broader controls of the Sahara Ni-Cu-PGE mineral system.
