LITHIUM CHILE MAILS INFORMATION CIRCULAR FOR SHAREHOLDER VOTE TO APPROVE US $175 MILLION SALE OF ARIZARO PROJECT

Lithium Chile Inc. has mailed its management information circular, together with the independent fairness opinion, in connection with the sale of its Arizaro project for $175-million (U.S.).

The transaction will be accomplished through the sale of the company's Argentine subsidiary, Argentum Lithium SA.

Mailing of the information circular will enable shareholders to review the details of the transaction and vote to approve the transaction at the company's coming annual general and special meeting of its shareholders, scheduled to be held on May 15, 2026.

Shareholder approval constitutes a key step toward completing the transaction, which remains subject to customary closing conditions, including receipt of Chinese outbound direct investment (ODI) approval and the acquisition of an additional 17.8-per-cent interest in the project from LitiAr SA, the company's joint venture partner. The company also confirms that all regulatory requirements in Salta province, Argentina, have been approved. The purchaser, China Union Holdings, continues to work diligently to secure ODI approval to facilitate the transfer of funds required to complete the transaction and has advised the company of its intention to close the transaction by June 30, 2026.

Steve Cochrane, president of Lithium Chile, commented: "This has been a complex transaction involving multiple jurisdictions, languages and time zones. We continue to receive co-operation from the parties directly involved with the transaction and we appreciate the continued support and patience of our shareholders as we work through the remaining requirements to close."

Shareholders are encouraged to review the information circular and vote their shares ahead of the special meeting. The information circular and related materials are also available on SEDAR+ and on the company's website.
