The objective of the Securities Trading Policy (the “Policy”) is to ensure that the employees, officers, directors and consultants (collectively, “Covered Persons”) of Lithium Argentina AG and its subsidiaries and joint venture interests (together with its subsidiaries and joint venture interests are referred to as the “Company” or “Lithium Argentina” herein) are in compliance with applicable laws, rules and regulations when they trade in securities issued by the Company, and comply with the requirements of the Company’s long-term equity incentive plan.

The Policy also extends to any trading by trusts and holding companies controlled by a Covered Person. The Company expects Covered Persons will ensure compliance by family and other members of their household.

The trading restrictions in this Policy will continue to apply after employment, or for any other relevant relationship between the Company and Covered Person and ceases for so long as the former Covered Person is in possession of material non-public information. No trading may occur until the information becomes public or ceases to be material. Transactions that may be necessary or justifiable for independent reasons, such as the need to raise money for an emergency expenditure, are no exception. Even the appearance of an improper transaction must be avoided.

Directors and certain officers, including the Company’s named executive officers, the principal financial and accounting officers, vice presidents in charge of principal business units, divisions or other functions and other officers who have similar policy-making authority (collectively, the “Section 16 Insiders”), are subject to additional requirements under the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The Company is a public company in Canada and the U.S. as its common shares are listed for trading on the Toronto Stock Exchange and the New York Stock Exchange. As such, the Company and its Covered Persons are subject to restrictions against trading in securities of the Company while in possession of material information that has not been publicly disclosed. Trading while in possession of material undisclosed information is generally known as insider trading.

“Trade in securities” or “trading in securities” when used in this policy includes, but is not limited to:

This policy does not apply in the case of the following transactions under employee plans, except as specifically noted:

"Director” means a member of the Board.

“Material Information” generally includes:

Insider trading prohibitions come into play only when you possess information that is material and "nonpublic." The fact that information has been disclosed to a few members of the public does not make it public for insider trading purposes. To be "public" the information must have been disseminated in a manner designed to reach investors generally, and the investors must be given the opportunity to absorb the information. Even after public disclosure of information about the Company, you must wait until the close of business on the second trading day after the information was publicly disclosed before you can treat the information as public.

“Nonpublic” information may include:

As with questions of materiality, if you are not sure whether information is considered public, you should either consult with the Chief Financial Officer or the Vice President, Legal & Corporate Secretary or assume that the information is nonpublic and treat it as confidential.

Covered Persons are prohibited under applicable securities laws and this policy from:

The Company will impose trading blackouts from time to time during which trading, including buying, selling or engaging in any other activities concerning the securities of the Company, will be strictly prohibited unless the transaction is subject to a Rule 10b5-1 plan.

Blackout periods will specifically apply to Covered Persons during the period commencing on the earlier of:

and ending on the day that is two full business days after the Company’s release of earnings to the public. The Chief Financial Officer may designate other blackout periods or adjust the start of the Year-End and Quarter-End periods if he/she deems it appropriate.

Covered Persons subject to the blackout period restrictions whose employment or other relationship with the Company terminates during a blackout period will remain subject to the restrictions until the end of the blackout period, regardless of the date of their departure or termination of the relationship, and ending on the day that is one full business day after the Company’s interim financial reporting for the Quarter or annual financing reporting for the Year-End is filed.

Covered Persons subject to the blackout period restrictions whose employment or other relationship with the Company terminates during a blackout period will remain subject to the restrictions until the end of the blackout period, regardless of the date of their departure or termination of the relationship.
