“Benagerie Dyke definition study” This report details exploration carried out by Havilah Resources Limited (Havilah) for the Round 3 (2021/2022 - Stage 2) Accelerated Discovery Initiative (ADI). Work was undertaken over the Benagerie Dyke project in the Curnamona Craton. A prominent linear aeromagnetic feature just west of Lake Frome termed the Benagerie Dyke, extends for > 30 km along the western rifted margin of the Benagerie Ridge. The origin is unknown as it has never been successfully drilled, but the geometry suggested it could be a mafic/ultramafic intrusive complex within the Mesoproterozoic Curnamona Craton and therefore prospective for PGE-Ni-Cu-Co-Au mineralisation. Consultants ExploreGeo designed a moving loop ground EM survey using a basement depth of 200- 300 m as suggested by the intersection of pillow basalts in drillhole LMN10-1, the only drillhole along the anomaly to pass through Palaeozoic/Mesozoic cover rocks. Unfortunately, initial evaluation suggested depth to magnetic basement is shallowest at the drillhole site but deepens significantly to the north and south (>300-400 m). The consultants advised that at these depths moving loop ground EM surveys are likely to be ineffective in locating disseminated sulphide PGE mineralisation. Detailed evaluation of unpublished geochemical and isotopic data for basalts in LMN10-1 show continental tholeiitic affinities with strong similarities to basal Adelaidean basalts found elsewhere – e.g. Wooltana and Beda Basalts and the Benagerie Dyke therefore most likely represents a dolerite or gabbro feeder system of which the basalts are an eruptive phase. Both dyke and basalt are almost certainly related to the Willouran Basic Province (WIB) and the breakup of Rodinia. As the result of this initial geophysical and geochemical work, Havilah has concluded that the original premise for the Benagerie Dyke PGE model has probably been disproven and therefore no further work on the Benagerie Dyke is warranted at this time.
