Hombre Muerto North Lithium Project
Located in Salta and Catamarca Provinces, Argentina. The property package of 3,287 hectares is comprised of the Alba Sabrina, Tramo, Natalia Maria, Gaston Enrique, Viamonte and Norma Edit concessions, all located in the Salar del Hombre Muerto in northwestern Argentina.
The Company has evaluated the Hombre Meurto North Lithium Project (HMN Li Project) having completed the initial exploration, a resource calculation, and releasing PEA numbers. The HMN Li Project is strategically located in the Hombre Muerto Salar, an area of active lithium production by FMC Lithium Co. at the Fenix lithium mine, some 12 kilometers south of the project area. The project is surrounded by ground now owned by POSCO, a Korean based lithium producer, as a result of its US$280 million purchase of the area from Galaxy Resources Ltd., an Australian-based producer. Galaxy Resources Ltd., is also moving their portion of the Hombre Muerto Salar, the Sal de Vida Project, to lithium production.
Highlights of the Hombre Muerto North Lithium Project include:
- Test work is underway for Direct Lithium Extraction (DLE) - an alternative to the conventional evaporation process currently used by the industry - and the process under development is demonstrating a doubling of Lithium Recovery from Brine (80% lithium recovery) which potentially will shorten lithium recovery time and provide higher recovery of lithium.
- PEA indicates attractive economics for a 5,000 tonne/year LCE operation with a CAPEX of $93.3M, OPEX of $3,112/t LCE, NPV(8) of $217M and IRR of 28.0%.
- Exceptional Li Samples; 300 - 400 meter average 918 mg/l Li with a low Mg to Li ratio.
- Excellent Pump Test Results - produced 26 liters per second of lithium brine in 72-hours.
- Geophysical data indicates zones of low resistivity, interpreted to be potential lithium-bearing zones that are open at depth.
- Adjacent to Galaxy Resources’ Sal de Vida lithium development project sold in May 2018 to Posco for US$ 280 Million.
- Highly qualified, Argentina-based team of professionals experienced with lithium exploration, development, through to lithium production.

" I personally feel very optimistic that DLE’s efficiencies will replace conventional Lithium extraction methods which are slow as they’re dependent upon extracting lithium from ponds via a solar evaporation process."
February 20, 2020 - Adrian Hobkirk, President and CEO of Lithium South, quoted,
"Lithium South is evaluating several new extraction technologies for lithium production which may be applicable to the project, all of which will require a substantial sample of brine."
August 12, 2019 - Adrian Hobkirk, President and CEO of Lithium South, quoted,
“We are very pleased to have completed and filed the report, which firmly established the Hombre Muerto North Lithium Project as having significant potential. The smaller environmental footprint, shortened build out time and excellent grade of lithium enhance the attractiveness of the project.”
April 29, 2019 - Adrian Hobkirk, President and CEO of Lithium South, commented,
“Lithium South has advanced the HMN Project from discovery to PEA in just under twelve months.

March 2021 - Doubling of Lithium Recovery from Brine using DLE
Direct Lithium Extraction (DLE) test work was completed by Chengdu Chemphys Chemical Industry Ltd. (Chemphys) utilizing its proprietary XFP-Lithium DLE process, which selectively extracts lithium ions from brine. Testing was performed at the Chemphys ISO certified facility in Chengdu, China. Independent check sampling was completed at the PONY Testing International Group Co Ltd., an ISO/IEC 17020 and ISO/IEC 17025 certified laboratory. All work was completed under the supervision of Don Hains of Hains Technology Associates of Toronto, Canada, who is acting as the Qualified Person.
TEST RESULT HIGHLIGHTS
- 80% lithium recovery from brine using Chemphys XFP-Lithium Direct Lithium Extraction (DLE) process
- Near doubling of lithium recovery rates from conventional evaporation extraction
- Bulk brine sample acquisition for pilot scale test work
Adrian Hobkirk, President and CEO of Lithium South, commented, "Lithium South is well funded and has the resources to achieve its objectives. Our strategy is to pursue both DLE and evaporation extraction technologies in tandem, so that the risk is minimized."

August, 23 2018 - Results for second drill hole up to 280 meters
- Lithium South’s second drill hole at the Hombre Muerto North project has been completed to a depth of 280.8 m, and the sample results demonstrate that excellent lithium values are present in the lower portion of the hole.
- Based on these encouraging results, as well as the excellent results from the pumping well located approximately 2.1 kilometers to the east, Lithium South has decided to drill a second pumping well adjacent to the second core hole. The target depth of this hole is 400 m.
July 10, 2018 - Initial results for second drill hole up to depth of 61.5 meters
- Initial sample results for the second core hole indicate excellent lithium values with very low Mg/Li ratios. The arithmetic average of three samples taken to a depth of 61.5 m is 719 mg/l lithium with a magnesium to lithium ratio ranging from 2.1 to 3.3.
Adrian Hobkirk, CEO of Lithium South commented, “We are encouraged to find high lithium grades in the first part of the second hole, and these results demonstrate the presence of lithium bearing brine across our Tramo property. We will have a more complete picture once this hole is completed and when we have the results of the pumping test from the large diameter hole completed adjacent to the first core hole.”
June 29, 2018 - Complete results for first drill hole from 300 - 400 meters
- Brine samples collected from 300 to 401 meters (m) show high grade values very similar to the assays previously reported for the samples from surface to a depth of 300 m, with an arithmetic average 918 mg/l lithium and a low magnesium to lithium ratio.
- The arithmetic average lithium concentration for all of the samples from the surface to a depth of 401 m is 900 mg/l, with a relatively low magnesium to lithium ratio of 3.0 to 1.0.
June 14, 2018 - Drilling continues to intersect high-grade brine from 100 - 300 meters
- Brine samples collected from 100 - 300 meters show high grade values very similar to the assays for the samples from surface to a depth of 100 meters, with an average 888 mg/l Li and a low Mg to Li ratio.
- The hole has been completed to a depth of 401 meters.
- Adjacent rotary drill hole for pump testing has been completed to a depth of 393 meters.
- Drilling has commenced on a second diamond core hole approximately 2.1 kilometers to the east of the first hole.
May 24, 2018 - Consistent high-grade brine intercepts over the first 100 meters of drilling
• The hole is now at 300.5 meters in clastic sediments, and brine samples are currently being collected from 300 to 100 meters. Drilling will resume after the sampling is completed.
• Adjacent rotary drill hole for pump testing is at a depth of 173 meters.
May 14, 2018 - Lithium South adds second drill onsite
May 2018 - Drill rig operational and drilling is progressing as planned
The first diamond core hole has been advanced to a depth of 105 meters with a target depth of up to 350 meters. The geological profile observed so far in the core is that of sand, gravel, and clay, with a small halite zone, consistent with the expected geology. Brine was encountered from the top of the hole, and samples have been taken every ten meters from the current depth back to surface using a double packer unit.
March 2018 - Installation of housing and buildings
Feb 2018 - Hombre Muerto CEO visit
The Lithium South management team recently completed a site visit to the Hombre Muerto North Lithium Project in Argentina. This exciting project is located in one of the highest grade salars in Argentina where FMC has conducted lithium extraction operations for many years. Our technical team, including the President of Chemphys, Dr. Yi Hua Dai, inspected the site. Road access is excellent and we should be able to kick off our drill program in a timely manner.
