Vancouver, British Columbia--(Newsfile Corp. - June 25, 2026) - Argentina Metals Corp. (TSXV: VLLC) (FSE: VA5) ("VLLC" or the "Company") is pleased to announce that the Company's common shares (the "Shares") have commenced trading on the Frankfurt Stock Exchange ("FSE") under the symbol "VA5".

"The commencement of trading on the Frankfurt Stock Exchange marks an important milestone for Argentina Metals. The FSE is one of the world's largest exchange-trading platforms by trading volume and serves as a gateway to one of the deepest pools of mining and natural resource investors in Europe. As a German entrepreneur who co-founded Frankfurt-listed Deutsche Rohstoff AG, one of Germany’s most successful publicly listed natural resources companies, I appreciate the importance of access to European capital markets and the value of a diversified international shareholder base. We expect our Frankfurt listing to increase the Company's visibility across Germany and the broader European investment community, enhance share liquidity and support our long-term growth strategy." — Dr. Titus Gebel, Chairman of Argentina Metals Corp.

The listing of the Company's Shares on the FSE, in addition to the TSX Venture Exchange, is expected to heighten exposure of the Company in the European marketplace, which features an investor base traditionally active in the junior mining sector. The Company is of the view that listing on the FSE will enhance its share liquidity and support the development of an active and engaged European investor base.

The Company is a reporting issuer in British Columbia and Alberta and will continue to satisfy its continuous disclosure obligations through SEDAR+. The FSE listing does not result in the issuance of any additional securities of the Company.
