(NASDAQ: SEAM) (CSE: SEAS) (OTCQB: DSEAF) (FSE: X450) Deep Sea Minerals Corp. announced its Silver Sponsorship and support of emerging researchers at the 2026 Underwater Minerals Conference (UMC) in Toyama, Japan. The UMC will be held from November 8 to 13, 2026, at the Toyama International Conference Center and is presented by the International Marine Minerals Society in partnership with the Japanese Local Committee. The conference theme is “Marine Minerals: Fostering Science, Innovation, and Stewardship.” Deep Sea Minerals Corp.'s participation will allow engagement with the international marine minerals community and discussion of scientific and technical developments relevant to its exploration strategy, including environmental baseline research and responsible seabed mineral development. Through its sponsorship, the company is supporting opportunities for two students and early-career researchers to participate at UMC, contributing to knowledge sharing and professional development in the marine minerals sector. James Deckelman, Chief Executive Officer of Deep Sea Minerals Corp., stated that the company is pleased to participate as a Silver Sponsor and to support two emerging researchers in sector discussions. Deep Sea Minerals Corp. is 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 centers on identifying jurisdictions and geological settings with potential exposure to polymetallic nodule systems, which contain combinations of metals relevant to defense, industrial manufacturing, clean energy infrastructure, advanced electronics, and artificial intelligence-related supply chains. 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. The company submitted an amended application for an exploration licence for a defined area of the Clarion-Clipperton Zone in the Pacific Ocean (the “NOAA Application”) under the Deep Seabed Hard Mineral Resources Act (DSHMRA) on July 17, 2026, in response to NOAA's notice dated May 26, 2026, requesting supplemental information. The company’s amended and restated annual information form for the year ended December 31, 2025, is dated July 27, 2026. The company is also considering submitting an application for an exploration licence in the exclusive economic zone of the Cook Islands (the “Cook Islands Application”) under the Cook Islands seabed minerals regime. The company’s ability to proceed with these applications is subject to regulatory, environmental, technical, and financial requirements, as well as the availability of equipment, qualified vessel operators, and marine contractors. The company’s plans are also subject to the outcome of federal-agency consultation, antitrust review, public-comment, certification, environmental-review, and hearing processes applicable to the NOAA Application. The company’s ability to obtain sufficient financing to fund regulatory, environmental, technical, and offshore activities is a key consideration. The company’s intended offshore operations may be delayed or prevented by regulatory, operational, environmental, financial, or other factors.
