CALGARY, ALBERTA, July 17, 2025 – TheNewswire - Lithium Chile Inc . (“ Lithium Chile ” or the “ Company ”), is pleased to announce that several directors and officers have exercised stock options previously granted under the Company’s stock-based compensation plan.

A total of 475,000 options were exercised at a price of $0.51 per share, generating $245,250 in proceeds to the Company. This insider participation reflects strong confidence in Lithium Chile’s strategy and the ongoing progress toward closing a transaction which is expected to monetize the Arizaro lithium project in Argentina.

The leadership team remains confident that the previously announced acquisition of the Arizaro project is advancing towards closing, with both parties working toward finalizing definitive agreements that reflect the material terms contained in the letter of intent entered into on December 15, 2024.

Michelle DeCecco, COO of Lithium Chile comments; “ While the Arizaro acquisition has taken longer than anticipated, the transaction terms remain unchanged with both parties fully committed to completing the transaction. The decision by our board members and the executive team of Lithium Chile to exercise options is a powerful endorsement in the Company’s ability to advance the Arizaro transaction and to exploit the Company’s remaining strong asset portfolio.  This includes our interests in the Coipasa salar in Chile, where Lithium Chile and its partner were recently awarded one of only three lithium development production contracts granted by the Chilean government.”
