LITHIUM SOUTH DEVELOPMENT Business Summary

Lithium South Development Corp (LISMF) is a pre-revenue junior mineral exploration company primarily focused on the development of its 100% owned Hombre Muerto North Lithium Project (HMN Li Project) in the Salta and Catamarca Provinces of Argentina. As of February 2026, the company’s business model has shifted from pure-play exploration toward a strategic liquidity event, centered on the proposed US$65 million sale of its primary subsidiary, NRG Metals Argentina S.A., to POSCO Argentina S.A.U. This transaction, pending shareholder approval on February 19, 2026, aims to monetize a high-grade resource of 1.58 million tonnes of Lithium Carbonate Equivalent (LCE). Within the competitive landscape of the "Lithium Triangle," Lithium South operates alongside industry titans such as Rio Tinto (following its acquisition of Arcadium Lithium), Albemarle, and Ganfeng Lithium. The company distinguishes itself as a high-quality asset holder situated in the premier Hombre Muerto salar, positioned as a prime acquisition target for major producers seeking to consolidate contiguous brine resources. The leadership team is anchored by Founder, President, and CEO Adrian F. C. Hobkirk, a 32-year veteran of the mining and venture capital sectors who has spearheaded the project since its inception. Key operational expertise is provided by Vice President Fernando E. Villarroel, an industrial engineer with extensive experience in lithium process development from his tenure at Lithium Americas Corp, and Claudio C. Zalewski, who was appointed in mid-2025 as Director of Development & Construction to oversee the project’s transition toward feasibility. Financial oversight is managed by CFO Christopher P. Cherry, a chartered accountant with over two decades of experience in public mining company audits. The company maintains a critical strategic relationship with major shareholder Chengdu Chemphys Chemical Industry Co. Ltd, represented on the board by Yi Hua Dai and Alison Dai, providing the firm with significant technical and financial backing from the Chinese lithium processing sector.
