(CSE: SEAS) (OTCQB: DSEAF) (FSE: X450) ("Deep Sea Minerals" or the "Company"), a seabed mineral exploration and development company focused on advancing critical mineral opportunities from the deep ocean, today welcomed the increased national focus on critical minerals and deep-sea mining demonstrated at President Donald J. Trump’s American Mining Roundtable, held August 7, 2026, at the U.S. Department of State. The U.S. government announced approximately US$3 billion in financing commitments for critical minerals and battery projects, together with more than US$180 million for mining education and workforce development. During his remarks, President Trump stated that his administration had “authorized deep-sea mining to unlock vast untapped resources off our coast.” Later in the roundtable, a participant presented the President with a gold replica of a deep-sea polymetallic nodule and described the potential role of seabed minerals in U.S. industrial, technological and defense supply chains. The Company believes the discussion reflects growing policy recognition of offshore mineral resources as one potential component of a diversified and secure U.S. critical-minerals strategy. “Deep sea minerals have moved firmly into the national conversation about economic security, defense readiness, and American industrial capacity,” said James Deckelman, Chief Executive Officer of Deep Sea Minerals Corp. “The attention given to deep sea mining at the American Mining Roundtable reinforces the importance of evaluating these resources through a transparent, science-led and responsible regulatory process. Deep Sea Minerals is working to build a disciplined platform aligned with U.S. critical-minerals priorities while maintaining a strong commitment to environmental stewardship and regulatory compliance.” Deep Sea Minerals Corp. continues to advance the regulatory, technical and environmental workstreams associated with its offshore critical mineral strategy. As previously disclosed, the Company submitted an exploration license application to the U.S. National Oceanic and Atmospheric Administration under the Deep Seabed Hard Mineral Resources Act of 1980 and received a substantial compliance determination in connection with that application. No exploration license has been awarded, the application remains subject to applicable regulatory review and approval, and the Company has not made a production decision. The Company believes that any future development of deep-sea mineral resources should proceed within rigorous environmental and regulatory frameworks, supported by scientific research, stakeholder engagement and transparent oversight. ABOUT DEEP SEA MINERALS CORP. Deep Sea Minerals Corp. is a seabed mineral exploration and development company focused on evaluating opportunities to support the future supply of critical minerals through the acquisition, exploration, and development of deep-sea mineral assets. The Company’s strategy is centered on identifying jurisdictions and geological settings with potential exposure to polymetallic nodule systems, which are recognized for containing combinations of metals that may be relevant to defense, industrial manufacturing, clean energy infrastructure, advanced electronics, and artificial intelligence-related supply chains. These seabed resources represent a largely undeveloped component of the global mineral supply base and are the subject of increasing policy, scientific, and regulatory attention worldwide. As part of this process, the Company has commenced early-stage engagement with selected governments and regulatory bodies in the Pacific Ocean region to assess potential pathways for future exploration initiatives, subject to applicable international, national, and environmental frameworks.
