DEEP SEA MINERALS CORP. COMMISSIONS DOCUMENTARY-STYLE VIDEO ON THE DEEP SEA MINING INDUSTRY

Deep Sea Minerals Corp. has released a company-commissioned documentary-style video entitled "An Inside Look At The Deep Sea Mining Industry," which features the company's chief executive officer, James Deckelman.

The video "An Inside Look At The Deep Sea Mining Industry" provides an overview of the emerging deep sea minerals sector, the role of polymetallic nodules as a potential source of critical minerals, and the broader strategic importance of developing diversified mineral supply chains for the United States and allied economies.

Mr. Deckelman's participation in the video highlights Deep Sea Minerals' perspective on the opportunity for responsible seabed mineral exploration, the importance of regulatory engagement, and the potential role that deep sea minerals may play in supporting future demand for metals used in the electrification, energy storage, advanced manufacturing, defence applications\ and next-generation infrastructure.

Deep Sea Minerals commissioned the video as part of its investor awareness, education and corporate communications program. The company believes that deep sea minerals are increasingly relevant within the broader macroeconomic context of critical mineral security, supply chain resilience and the need for new sources of strategic metals.

"Critical minerals are no longer just a mining issue, they are an economic security, industrial policy and national security issue," said James Deckelman, chief executive officer of Deep Sea Minerals. "We commissioned this video to help explain the deep sea minerals sector and why polymetallic nodules are receiving increased attention as governments and industry look for additional sources of strategic metals. While the industry remains early stage and, subject to, among other things, extensive regulatory, technical, environmental, and commercial requirements and risks, we believe it is important to contribute to a more informed public discussion."

Deep Sea Minerals' strategy is focused on advancing its exploration-stage initiatives, engaging with applicable regulatory pathways, building relationships with technical and environmental service providers, and positioning the company to participate in the potential development of a responsible deep sea minerals industry. The company remains committed to evaluating its activities in accordance with applicable laws, environmental requirements, stakeholder expectations and public company disclosure standards.

About Deep Sea Minerals Corp.

Deep Sea Minerals 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 centred 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 defence, 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.
