LUMINA METALS COMMENCES TRADING ON THE WARSAW STOCK EXCHANGE

Lumina Metals Corp.'s common shares have been admitted to and have commenced trading on the main market of the Warsaw Stock Exchange under the ticker symbol LMCU. The common shares continue to trade concurrently on the Toronto Stock Exchange under the same symbol, LMCU.

The admission and introduction of the common shares to trading on the WSE complete the dual listing contemplated at the time of the company's initial public offering, which closed on April 30, 2026, and follows the approval by the Polish Financial Supervisory Authority of the company's Polish-language prospectus prepared in accordance with Regulation (European Union) 2017/1129. The common shares trade on the WSE under ISIN CA55025J1030.

The common shares admitted to trading on the WSE are of the same class as, and rank equally with, the common shares listed on the TSX. No new common shares were issued in connection with the admission to trading on the WSE.

The listing on the WSE establishes a direct presence for Lumina in the Polish capital markets and reflects the company's long-term commitment to Poland, where it has operated since 2011.

"We were pleased to engage with Prime Minister Tusk and many other senior government officials at the Warsaw Stock Exchange today. Their presence reflects the increasing importance of critical raw materials to Poland, Europe and allied countries, and the role that new domestic copper and silver production can play in supporting long-term economic growth and supply chain security. Our WSE listing provides Polish institutional and retail investors with the opportunity to participate directly in the development of these strategically important resources," said Jordan Pandoff, chief executive officer of Lumina Metals.
