Deep Sea Rare Minerals, Inc. Enters Into Engineering and Design Agreement with Consortium of Subsea Equipment Providers

DSRM 's Strategy is to Become Extraction Ready in 2028

MT. PLEASANT, SC / ACCESS Newswire / December 1, 2025 /Deep Sea Rare Minerals, Inc. ("DSRM" or the "Company"), the parent company of autonomous underwater vehicle operator and subsea survey company Deep Sea Vision, LLC ("DSV"), announced today that it has entered into a Front-End Engineering and Design ("FEED") Agreement with a consortium of subsea equipment engineering and manufacturing companies. The Agreement represents the initial phase in the design, development, and evaluation of a next-generation, ultra-deepwater polymetallic nodule harvesting system.

Under the Agreement, a business unit of Oil States International, Inc. (OIS; www.oilstatesintl.com) will serve as the prime contractor. Several additional U.S.-allied subcontractors will be providing specialized engineering and technical support.

DSRM is advancing the conceptual and technical framework needed to enable potential future U.S.-based recovery operations for polymetallic nodules. Working alongside its engineering partners, DSRM aims to create and refine technologies intended to improve both subsea and surface handling efficiency while maintaining the highest environmental and operational standards.

Tony Romeo, DSRM 's Founder and Chief Executive Officer and a former U.S. Air Force Intelligence Officer, stated:

"Our momentum in the polymetallic mineral exploration space continues to build. We believe we have aligned with a world-class team of partners-including our U.S.-based design team lead, Oil States International-to advance the engineering of our bespoke harvester system. Our strategy-to accelerate subsea mineral exploration, site planning, and extraction equipment design and manufacturing-may enable the Company to become extraction-ready as early as 2028. These efforts align with President Trump 's critical minerals strategy and the April 24, 2025 Executive Order, Unleashing America 's Offshore Critical Minerals and Resources (www.noaa.gov/news-release/next-gold-rush-president-trump-unlocks-access-to-critical-deep-seabed-minerals). We remain committed to contributing to the responsible development of critical mineral supply chains that support America 's economic and national security."

Garry Stephen, Oil States Vice President, commented:

"Oil States is pleased to have been selected by Deep Sea Rare Minerals to help advance their plans to evaluate and potentially commence commercial deep-sea mineral recovery. Building on our track record as a global leader in deepwater minerals-gathering systems, our engineering analysis and field-proven technologies support rapid operational start-up and long-term reliability, even in remote and challenging deepwater environments. Having supported two successful deep-sea mineral trials in late 2022 and holding the world record for a producing riser operating at 4,500 meters (14,764 feet), we look forward to leveraging this experience as we work with the DSRM team on this next-generation system."
