Lithium Resource Expansion Complete

Lithium South is developing its Hombre Muerto North Lithium Project.  With a solid maiden resource, and the expansion drill program now complete, we look forward to full results and the delineation of a new lithium resource.  The Alba Sabrina claim returned exceptional high-grade, low impurity lithium brine.  The Company objective is to expand the current NI 43-101 lithium resource.

  • Office and laboratory located in Salta, Argentina
  • World renowned, Vijay Mehda, technical consultant and qualified person
  • Dr. Mark King, a Qualified Person (QP) under NI 43-101 is supervising the 2022-23 drill program

High Quality Brine Resource

  • High quality, low impurities brine
  • High-grade lithium brine – 756 mg/L
  • Low Mg/Li ratio – 2.6:1
  • A high-grade, low impurity brine equates to lower capital expenditure
  • 2022-23 drill program results indicate a large high-grade, low magnesium brine zone

Solid 2019 PEA Results

  • Preliminary Economic Assessment completed 2019 on 5,000 TPA LCE
  • Current resource based on only 14% of the total project area
  • Current LCE market price considerably higher than 2019

The objective of the drill program is to potentially expand the current Lithium Carbonate Resource.

  • 8 core hole drill program on largest claim block in Argentina’s world-class Salar del Hombre Muerto
  • Alba Sabrina claim is the largest of the nine claim blocks totaling 5,687-hectare HMN Li project.
  • PEA: 571,000 tons Lithium Carbonate Equivalent (M&I) on just 14 percent of the property.
  • 2022-23 resource expansion drill program has yielded impressive lithium grades from all 7 drill holes at Alba Sabrina claim and 1 hole on Natalia Maria claim block
  • Alba Sabrina drill program returned an average lithium concentration of 692 mg/liter lithium
  • The Natalia Maria core hole returned an average of 1176 mg/liter lithium

Company President Adrian F. C. Hobkirk is quoted,
“The resource exploration has consistently returned excellent results.  Holes located to the west of the claim area are delineating the Alba Sabrina salar channel to be wider than expected, which could positively impact the expansion of the total resource at the Hombre Muerto North Lithium Project.”
