ANNUAL MEETING OF SHAREHOLDERS OF LITHIUM ARGENTINA AG
(the "Meeting")

NOTICE-AND-ACCESS NOTIFICATION TO SHAREHOLDERS

You are receiving this notification as Lithium Argentina AG (the "Company") has decided to use the notice-and-access model for delivery of Meeting materials to its shareholders. Under notice-and-access, shareholders still receive a proxy or voting instruction form enabling them to vote at the Meeting. However, instead of a paper copy of the management information circular (the "Circular"), shareholders receive this notice with information on how they may access such materials electronically. The use of this alternative means of delivery is more environmentally friendly as it will help reduce paper use and also will reduce the cost of printing and mailing materials to shareholders. We remind you to access and review all of the important information contained in the Circular and other proxy materials before voting.
