Lithium Resource Expansion Underway

Lithium South is developing its Hombre Muerto North Lithium Project.  With a solid maiden resource, an expansion drill program is underway to increase the resource size.  The Alba Sabrina claim block is returning exceptional high-grade lithium results. The Company objective is to potentially expand the current NI 43-101 lithium resource to 2 million tonnes Lithium Carbonate Equivalent.

Project Highlights

Mining Friendly Province, Salta Argentina

  • History of lithium production
  • Mining friendly jurisdiction
  • Prime location on world renowned
    Hombre Muerto Salar
  • Excellent access, with gas and water sources
  • Project claim surrounded by Korean giant POSCO

Resource Expansion Drill Program Underway

  • Drill rigs on site for an 8 hole program on Alba Sabrina claim
  • Drilling to date has delineated a brine sub basin approximately 1.2 km wide by 7.6 km in length
  • Current drill program offers potential to substantially expand current Lithium Carbonate Equivalent (LCE) resource
  • Drill program near completion and calculation of upgraded lithium resource anticipated in Q2 of 2023

Feasibility Study Progress

  • Feasibility study to be completed 2023 based on upgraded resource size
  • Environmental Study near completion
  • Topographical Study underway
  • A feasibility study evaluates whether a mining project is economically and technically possible, how much investment is required to build out.

Qualified Proven Team

  •  Very strong technical lithium experience
  • 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
  • New upgraded Preliminary Economic Assessment (PEA) anticipated in 2023

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.
  • The resource expansion drill program is comprised of four core wells (Holes AS01, AS02, AS03 and AS04) located north to south, and three monitor wells (Holes AS05, AS06 and AS07) located west of the core wells.
  • The final core well AS02 has been completed to a depth of 410 meters, assays pending.
  • The overall average of the three wells sampled to date is 740 mg/l Li.

Company President Adrian F. C. Hobkirk is quoted,
“The ongoing exploration is returning consistently 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.”
