Warsaw, Poland--(Newsfile Corp. - May 19, 2026) - Lumina Metals Corp. (TSX: LMCU) ("Lumina" or the "Company") is pleased to announce that the Polish Financial Supervision Authority ("KNF") has approved its Prospectus prepared in connection with the application to trade on the regulated market operated by the Warsaw Stock Exchange ("WSE"). The approval of the Prospectus represents a significant step toward listing the Company's shares on the WSE as part of a dual listing.

The dual listing of the Company's shares in Poland and Canada will strengthen its capital markets position, significantly increasing its visibility in Poland and the broader European region. It will also enable greater liquidity and allow Polish investors to participate in the Company's growth.

"The approval of the Prospectus by the KNF is an important milestone for Lumina," said Jordan Pandoff, CEO of Lumina Metals. "It creates an opportunity for Polish investors to gain exposure to domestic critical raw materials which are essential to Europe's energy, technology, and defense sectors. A listing on both the WSE and TSX will strengthen Poland's leading position as a key global supplier of copper and silver while growing the country's capital markets sector."

Details regarding the date of the first day of trading on the WSE as well as the timeline for the listing of the Company's shares on the Warsaw market will be announced once approval from the WSE is received.

Trigon Dom Maklerski S.A. acted as an investment firm within an international syndicate of investment banks responsible for the IPO of Lumina.

White & Case M. Studniarek i Wspólnicy advised the company on the procedure for the approval of the prospectus by the KNF and the process of listing the shares on the WSE.
