Strategic Elements Ltd (ASX:SOR) has completed a detailed ground-based geophysical survey to generate drill targets at the newly acquired Leviathan Copper-Gold-Rare Earths Project in WA’s remote Gibson Desert.
The survey was designed to follow up a gravity anomaly identified from a wider-spaced regional gravity survey released early this year.
SOR’s aim was to generate detailed data applicable for modelling and develop drilling targets.
Modelling being conducted
3D inversion and forward modelling is now being conducted by Southern Geoscience Consultants and is expected to be reported within the next few weeks.
The company has applied for drilling funds from the WA Government's Exploration Incentive Scheme (EIS) for the project.
Companies awarded funding under the current round of the EIS will be notified in November 2019.
Large anomaly identified
Leviathan consists of a gravity anomaly of approximately 4 kilometres surrounded by up to 100 suspected volcanic pipes reported from previous diamond exploration.
The regional anomaly was not visible until new gravity data became available in 2019 and therefore has no previous exploration.
It is considered prospective for copper-gold-rare earths mineralisation related to volcano-intrusive complexes.
Historical drill records viewed by the company contain multiple references to disseminated sulphides.
Volcanic pipe confirmed
Recent petrographic analysis of historical drill core by Dr Franco Pirajno confirmed a volcanic pipe with fragments of galena (lead sulphide) and chalcopyrite (copper sulphide).
From Dr Pirajno’s work SOR believes the Leviathan gravity anomaly is the top of an alkaline intrusion and potential associated carbonatite surrounded by volcanic pipes identified in De Beers drill cores and magnetic data.
Dr Pirajno is a recognised global expert on mineral systems, with more than 50 years of experience, in industry, academia and government.
He has considerable knowledge in tectonics and ore deposit geology in Europe, southern Africa, South East Asia, New Zealand, southwest Pacific, China, southern Siberia, Greenland and Australia.
