Project: Hombre Muerto North Highlights

  • Test work is underway for Direct Lithium Extraction

    Test work is underway for Direct Lithium Extraction (DLE) – an alternative to the conventional evaporation process which potentially will shorten lithium extraction time and provide higher recovery of lithium.

  • Exceptional Pump Test Results

    Tests show 26 liters per second of lithium brine in 72-hours.

  • Succesful Resource Expansion Drill Program and Expanded PEA

    The corporation has been engaged in drilling activities on the Alba Sabrina & Santa Maria claim blocks to expand its resource base, resulting in an 175% increase in Measured and Indicated resources as well as a new 15,000 tonne per annum Preliminary Economic Assessment resulting in an impressive Net Present Value (8%) of 934 million USD.

  • Highly Qualified Management

    Highly qualified, Argentina-based team of professionals experienced with lithium exploration, development, through to lithium production.

Company Description

Lithium South Development is developing its Hombre Muerto North Lithium Project to supply future lithium demand. The Company objective is to move the project to production in the near future, utilizing either Direct Lithium Extraction Technology or Conventional Evaporation. The Company is evaluating both recovery processes in parallel.”

Key takeaways:

1. High Grade & Low impurity levels

Hombre Muerto North boasts high grade brine with very low combined sulphate and magnesium impurity levels.

2. Partnered with chemistry giant Chemphys

The company has established a strategic partnership with Chemphys, a prominent chemical company based in China. As part of the partnership, Chemphys has secured a 100% off-take agreement from the Hombre Muerto North project.

3. Evaluating technologies to optimize production processes, both conventional and DLE

The company is currently evaluating technologies that could optimize the use of resource together with EON Minerals that has a laboratory in Salta, Argentina. Both conventional processes and Direct Lithium Extraction (DLE) are being evaluated. 

4. Resource expansion drill program

A very successful resource expansion drill program 2022/2023 resulted in a 175% increase in measured and indicated resources of high-grade low-impurity lithium brine.
