U.S. and Japan Identify Atlas Lithium's Neves Project for Potential Government Financial Support in Landmark Critical Minerals Partnership

Governments of the United States and Japan Considering Financial Support for Atlas Lithium's Neves Project

Atlas Lithium Corporation (NASDAQ: ATLX) ("Atlas Lithium" or "Company"), a leading lithium exploration and development company, is pleased to announce that its 100%-owned Neves Project in Brazil's Lithium Valley is named in the Joint Fact Sheet for Japan-U.S. Critical Minerals Project Cooperation (the "Joint Fact Sheet") and is the only Brazil-based lithium project named in such list. The Joint Fact Sheet was released on March 20, 2026 by Japan's Ministry of Economy, Trade, and Industry ("METI") together with the Ministry of Foreign Affairs of Japan ("MOFA") and is available at https:www.meti.go.jppress2025032026032000120260320001-e.pdf. Notably, the Joint Fact Sheet states that the Government of Japan and the Government of United States are considering financial support for the purpose of development of the Neves Project.

The Joint Fact Sheet follows the U.S.-Japan Critical Minerals Investment Ministerial held on March 14, 2026, in Tokyo among the U.S. Department of the Interior, the U.S. Department of Energy, the U.S. Environmental Protection Agency, and Japan's METI. It also follows the summit held between Japan's Prime Minister, Sanae Takaichi, and U.S. President, Donald Trump, on March 19, 2026. Both governments have set out an action plan towards strengthening secure and diversified critical minerals supply chains for Japan, the United States, and global markets, building upon the Framework for Securing the Supply of Critical Minerals and Rare Earths through Mining and Processing signed on October 28, 2025, in Tokyo. The Joint Fact Sheet lists projects that can potentially contribute towards strengthening the critical minerals supply chain, including the Atlas Lithium Neves Project.

Atlas Lithium's inclusion in the Joint Fact Sheet is particularly notable given the Company's existing strategic partnership with Mitsui & Co., Ltd., one of Japan's largest global trading and investment companies. In March 2024, Mitsui made a US$30 million strategic investment in Atlas Lithium common shares and entered into an offtake agreement for the purchase of lithium concentrate from the Neves Project. Mitsui's equity interest in Atlas Lithium, as recognized in the Joint Fact Sheet, provides a direct commercial bridge between the Neves Project and Japan's industrial base.

Marc Fogassa, CEO and Chairman of Atlas Lithium, commented: "The inclusion of the Neves Project in the Japan-U.S. Critical Minerals Joint Fact Sheet, with both the U.S. and Japanese governments considering financial support for our project, is a powerful recognition of the strategic value of our assets and the progress that our team has achieved. Together with our strategic partner Mitsui & Co., we remain focused on bringing the Neves Project into production and supplying high-quality lithium concentrate to the global market. We are also proud of working with the local communities in bringing progress to an economically disadvantaged area of Brazil."
