LION COPPER CORP. COMMENCES TRADING ON NASDAQ UNDER SYMBOL "LCU" AND RETAINS RENMARK FINANCIAL COMMUNICATIONS USA INC.

Lion Copper Corp.'s common shares have commenced trading on the Nasdaq Capital Market under the ticker symbol LCU, effective Oct. 19, 2026.

The Nasdaq uplisting represents a significant milestone in Lion's corporate development and reflects the company's continued progress in advancing its flagship Yerington copper project in Nevada.

The listing is expected to enhance Lion's visibility within U.S. capital markets, broaden access to institutional and retail investors, and provide an established U.S. trading platform as the company advances toward completion of its definitive feasibility study (DFS) and the next phase of project development.

Advancing a significant U.S. copper development opportunity

Lion's flagship Yerington copper project is located in Lyon county, Nevada, within a historic copper-producing district containing mineral resources and established regional infrastructure.

The company completed a prefeasibility study in 2025 and is currently advancing a DFS, targeted for completion in the first quarter of 2027, in parallel with permitting and other project development activities.

The Yerington copper project is planning for the production of copper cathode, positioning Lion to potentially contribute to the growing demand for domestically produced copper supporting U.S. electrical infrastructure, energy development, advanced manufacturing and the digital economy.

The company believes that its Nasdaq listing provides an important capital markets platform as it progresses the Yerington copper project toward future development and financing decisions.

Strategic benefits of the Nasdaq listing

The company expects its Nasdaq listing to provide several potential benefits:

• Expanded investor access: broader accessibility to U.S. retail and institutional investors;
• Enhanced market visibility: increased exposure within U.S. capital markets and the domestic copper and critical minerals sectors;
• Improved trading platform: access to Nasdaq's established trading infrastructure, with the potential to support greater market participation and liquidity;
• Institutional positioning: increased visibility among institutional investors as Lion advances feasibility, permitting and future development financing activities;
• Alignment with U.S. copper development: a U.S. exchange listing that complements the company's strategy of developing a significant domestic copper resource.
