Vancouver, BC, April 13, 2026 – Deep Sea Minerals Corp. (CSE: SEAS) (OTCQB: DSEAF)

(FSE: X45 0) ("Deep Sea Minerals" or the "Company") , a subsea mineral exploration and

development company focused on advancing critical mineral opportunities from the deep ocean,

is pleased to announce the appointment of Dan McConnell as Vice President of Exploration.

Mr. McConnell has 25+ years of deepwater marine geoscience experience, with a specialization

in high- resolution geophysics applied to deepwater environments. Over the course of his

distinguished career, he has served as a research and development advisor to the U.S. Department

of Energy and is widely recognized as an expert in deepwater seafloor mapping and geological

interpretation. He has extensive operational experience in deepwater vessel contracting and survey

specifications, developed through senior roles with Fugro, a gl obal leader in geophysical and

geotechnical services, and as a principal shareholder of AOA Geophysics, a specialized

consultancy focused on electromagnetics and advanced seafloor mapping technologies.

Mr. McConnell has played a key role in the advancement of polymetallic nodule exploration,

having served as lead geologist on multiple resource surveys in the Clarion Clipperton Zone , one

of the world’s most prospective regions for critical seabed minerals. He was also a principal author

of the “Resource Evaluation of Critical and Hard Offshore Mineral Programmatic Reference” a

comprehensive assessment of known and prospective offshore mineral deposits across the U.S.

and Territorial Outer Continental Shelf published in 2023 by the U.S. Bureau of Ocean Energy

Management (BOEM), now reorganized as the U.S. Marine Minerals Administration.

Recognized by offshore operators and contractors across the offshore energy sector, Mr.
