Argosy Minerals Limited announced that it has reviewed geophysical gravity data at its 100% owned Tonopah Lithium Project in Nevada, USA, which has identified lithium brine trap targets that may contain accumulated concentrated lithium brine, that will be the focus for Argosy's exploration works at the Project. The gravity data was previously modelled to create a 3D depth inversion model of the basin to define sub-basins that may be sites for lithium brine accumulation. The 3D inversion model shows: northeast depth gradients crossing the Northwest Clayton Valley basin caused by normal faults which define boundaries of sub-basins; the sub-basins are targets for traps for the concentration of lithium brine from groundwater flow from the northwest toward the Silver Peak lithium brine operation; and the Northwest Clayton Valley basin in the central part of the Tonopah Project area has basement depths of greater than 3,000m ­ highlighting the depth potential for accumulation of lithium brine areas. The lithium brine trap targets identified from the 3D inversion modelling will allow the Company to progress potential follow-up magnetotelluric resistivity surveying and drilling works to determine lithium brine prospectivity. The Project is directly analogous to the neighbouring Silver Peak Lithium Mine (owned by Albemarle Corporation) deposit model, both geologically and structurally, with consultants SRK providing positive validation of the lithium brine resource potential following their prior technical review. The Tonopah Project provides a low-risk opportunity to take an early stage lithium brine prospect and apply the Argosy strategy ­ as demonstrated at Rincon Lithium Project, to similarly advance Tonopah. The Project is located in one of the world's most favourable and stable mining jurisdictions and home to the USA's burgeoning electric vehicle industry, with well-developed infrastructure and a skilled local workforce.
