DEEP SEA MINERALS CORP. WELCOMES GROWING U.S.

FOCUS ON DEEP-SEA MINING AT AMERICAN MINING

ROUNDTABLE

Vancouver, British Columbia – August 11, 2026 – Deep Sea Minerals Corp. (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 min ing 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.

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.
