Lithium South Announces PEA Estimate

US$934 Million Dollar NPV with an IRR of 31.6% and a 2.5 year Payback for HMN Lithium Project

Lithium South has advanced the HMN Lithium Project to a PEA based on 15,600 tonnes per year lithium carbonate technical grade production. The PEA results highlight attractive economics associated with the project, including a short payback and exceptional Internal Rate of Return. We look forward to taking the HMN Lithium Project to the next stage of development as quickly as possible.
