LITHIUM CHILE PRE-AWARDED CHASCHA SUR CONCESSION ADJACENT TO

ARIZARO PROJECT, SECURING KEY WATER RESOURCE

TSX Venture Exchange: LITH For Immediate Release

OTC-QB: LTMCF

CALGARY, ALBERTA, April 15, 2025 – Lithium Chile Inc. (“Lithium Chile” or the “Company”), is

pleased to announce that it has been pre-awarded the "Mining Tender Nº 03/24 for the Study,

Prospecting, Exploration, and eventual Exploitation of the Exclusive Zones of Special Interest

CHASCHA SUR – Salar de Arizaro", located in the Province of Salta, Argentina.

This important advancement represents a strategic milestone for the Company, as the CHASCHA

SUR block is adjacent to its flagship Arizaro Project and hosts a freshwater resource critical to a

future production plant. The anticipated concession of CHASCHA SUR by REMSa (Recursos

Energéticos y Mineros de Salta S.A.) enhances the technical and economic viability of the Arizaro

development, positioning it to meet its long-term production and sustainability goals. Currently,

two applications for water use, submitted by the Company, are under review by the

corresponding authority, the Secretariat of Water Resources of the Province of Salta.

“We are extremely pleased with the outcome of this tender,” commented Michelle DeCecco,

Vice President and COO of Lithium Chile. “The CHASCHA SUR block not only complements our

existing footprint on the Arizaro Salar, but it directly addresses one of the most vital elements of

any lithium production operation—fresh water, subject to its future granting by the Secretariat

of Water Resources. This development underscores the project’s valuation and reinforces it as a

compelling acquisition opportunity.”

The tender was conducted by REMSa, the provincial energy and mining corporation, through a

public and competitive process. Lithium Chile’s strong technical proposal and proven track

record of responsible exploration and development were key to its success.

The Company is now preparing for the formal award and will provide further updates as the

process advances. For competitive reasons details will be released at a future date.
