Dempsey Minerals Limited (ASX:DMI) is progressing with its due diligence work over the Salar de Hombre Muerto project in Argentina with a geophysics program to be carried out over the lithium brine project.
The ASX-listed explorer has begun gravity and CSAMT surveys at the project – which lies in the Catamarca Province – with the objective of defining the geometry and depth to basement of the salar and Los Patos channel, as well as map resistivity contrasts to help identify potential lithium-bearing brine aquifers.
The gravity survey consists of around 225 sites situated over 6 profiles. The CSAMT survey will cover 22.4km over five profiles. A CSAMT survey over a salar environment is expected to provide a depth of investigation in excess of 400m although this is dependent on the actual surface conductivity.
According to Dempsey, these geophysical methods have proved to be very successful on the Hombre Muerto salar in the region.
The Company has engaged highly regarded geophysical contractors Quantec Geoscience to conduct this work. Quantec has significant experience in this type of exploration targeting lithium brine mineralisation and has conducted work at the neighbouring Sal de Vida project for Galaxy Resources.
It is anticipated that the full interpretation and report will be available within about 4 weeks.
The project lies within the South American Lithium Triangle in the Hombre Muerto Basin, one of the most important and prolific salt flats in Argentina and indeed the world, and is situated adjacent to Galaxy Resources’ Sal de Vida project and FMC’s Fenix lithium operations.
The basin is known to have the lowest impurity levels of any producing Salar in Argentina and has been in production for over 20 years.
Dempsey has largely completed its due diligence work over the Hombre Muerto salar projects which it is acquiring from Australian private company Blue Sky Lithium.
A shareholder meeting will take place on 4 May to consider a range of resolutions in connection with the transaction including a change in the nature and scale of activities, approval of the Blue Sky transaction and capital raisings to assist in progressing the project.
