Hombre Muerto South – Lithium

The Hombre Muerto South (HMS) lithium project spans ca. 60,000 hectares in the Hombre Muerto basin, Argentina’s most prolific lithium brine basin situated in South America’s “Lithium Triangle”.

The Hombre Muerto basin ranks in the top quartile globally in terms of lithium concentrations, low magnesium-to-lithium concentrations, and low operational costs. Projects and licences in the vicinity of the HMS Project hold an impressive post-tax NPV in excess of US$20 billion in the aggregate.

We have a 100% interest in the HMS Project. It is the last undrilled lithium brine project of such material size in Argentina, the fastest growing lithium producing country in the world.

In August to September 2023, we acquired 40 line kilometres of CSAMT (Controlled Source Audio-Magnetotellurics) and 15 line kilometres of DCIP (Direct Current Induced Polarisation) surveys with Quantec Geoscience, the largest provider of non-seismic ground geophysical services. These surveys have confirmed the presence of substantial low-resistivity brines, indicating the potential for significant lithium brine resources.

ICP-MS (Inductively Coupled Plasma Mass Spectroscopy) analysis of salt crust samples by SGS, the world leading testing, inspection, and certification company, reveals lithium concentrations of ca. 950 mg/Kg, further evidencing the presence of an active lithium brine system.
