Lithium South closes Hombre Muerto North sale
Lithium South Delists After POSCO Deal Closes at $0.505 Per Share

Executive Summary
- Lithium South Development Corp. confirmed the completion of the sale of its wholly-owned subsidiary, NRG Metals Argentina SA, and the Hombre Muerto North lithium project to Posco Argentina SAU (99%) and Posco Holdings Inc. (1%).
- The transaction closed on April 7, 2026, in Buenos Aires.
- Shareholders are receiving cash consideration of $0.505 per common share pursuant to a plan of arrangement.
- The company is applying for delisting from the TSX Venture Exchange and OTCQB and will cease reporting status immediately following the transaction.
- Registered shareholders must submit a letter of transmittal to Computershare Investor Services Inc. to claim proceeds; non-registered shares are handled via intermediaries.
Material Impact
- The news confirms the execution of a previously announced asset sale (Share Purchase Agreement signed December 2025, Closing Date set March 2026).
- The share price has already consolidated at $0.47-$0.50 leading up to the close, pricing in the $0.505 offer value.
- There is no new upside catalyst; the event represents a liquidity exit for shareholders rather than an operational milestone.
- The transaction removes the company from public markets, effectively ending trading opportunities on TSX-V or OTCQB.
- Given the price was known and the market had priced it in over the preceding months (rising from $0.35 to $0.50), this is a routine confirmation of terms rather than a surprise material event.
