Glomar Minerals

American seabed minerals company, Washington, DC

PrivateFounded 2025

Glomar Minerals holds two International Seabed Authority exploration contracts in the Pacific Clarion-Clipperton Zone (CCZ) through its wholly owned subsidiary UK Seabed Resources Limited (UKSR): UK1 and UK2, plus a 19.9% interest in a third contract area held by Ocean Mineral Singapore. The company is named after the Hughes Glomar Explorer, the vessel the Central Intelligence Agency commissioned to recover the Soviet submarine K-129 and that Lockheed Martin later used to demonstrate nodule collection in the same zone.

Glomar has no listed shares. Its public market exposure runs through its processing partner, Cobalt Blue Holdings Limited (ASX: COB), with which it is developing Project Infinity, a proposed United States polymetallic nodule refinery.

News and articles

Overview

Glomar is building a single American chain from seafloor to refined metal.

• Offshore, UKSR holds the license areas and has surveyed the CCZ since 2013.
• Onshore, Project Infinity would refine nodules into manganese products, cobalt sulphate, nickel, copper and a rare-earth-rich residue.
• Polymetallic nodules sit unattached on the abyssal plain and carry manganese, nickel, copper, cobalt and rare earths in a single rock.
• Glomar cites Hein et al. (2012) for CCZ-wide totals of 274 million tons of nickel, 5,992 million tons of manganese, 44 million tons of cobalt, 226 million tons of copper and 15 million tons of rare earths. Those are zone-wide figures, not a resource for Glomar’s blocks.
• Glomar has published no resource or reserve statement for UK1 or UK2.

License areas

UK1 and UK2 together are about the size of Louisiana. All three areas lie in the Clarion-Clipperton Zone at 4,000 to 6,000 meters, more than 600 miles from the nearest settlement.

Project Infinity

Project Infinity is the consortium Glomar announced with Cobalt Blue Holdings on 29 March 2026, and which Cobalt Blue announced to the ASX the following day. It pairs Cobalt Blue’s refining flowsheets and Australian pilot plants with Glomar’s CCZ licenses, and aims to build the first commercial-scale polymetallic nodule processing facility in the United States.

• Design throughput: 200,000 tons of polymetallic nodules and 7,500 tons of terrestrial cobalt hydroxide a year.
• Products: refined manganese, cobalt sulphate, nickel metal, copper metal, and a residue rich in rare earth elements for downstream processing.
• Process: a closed-loop circuit built from modular units proven at pilot scale, with no process liquids discharged.
• Sites: four finalists across Louisiana, North Carolina and Texas, announced 15 June 2026, now in techno-economic evaluation.

The current campaign

UKSR’s fourth CCZ research cruise left Tahiti on 29 July 2026 for a 65-day survey of UK2, the first comprehensive geological and biological survey of that block in >40 years. It runs with Earth Sciences New Zealand aboard the research vessel RV Tangaroa.

Samples feed both UKSR’s resource model and the processing design for Project Infinity.

UKSR’s three earlier cruises produced >57,000 seafloor images, 27,000 biological samples and 70 peer-reviewed publications.

Ownership and how the licenses changed hands

The contracts have had three owners in four years. Companies House dates each handover.

• UK Seabed Resources Limited was incorporated on 4 May 2012 as a Lockheed Martin subsidiary. Lockheed Martin UK Holdings Limited was registered as its person with significant control on 6 April 2016.
• Lockheed Martin ceased to be the controlling party on 14 March 2023, when UKSR was sold to the Norwegian company Loke Marine Minerals. A deed of novation and guarantee dated March 2023 sits in UKSR’s public document set.
• Walter Sognnes, Loke’s co-founder, was registered as a person with significant control on 13 November 2023.
• Loke Marine Minerals declared bankruptcy in Bergen on 3 April 2025, putting the two exploration licenses into a Norwegian insolvency process.
• Glomar Minerals Ltd was incorporated in the United Kingdom on 24 April 2025, with Raphael Isaac Meir Diamond, who goes by Robbie Diamond, registered as a person with significant control from that date.
• Glomar Minerals Ltd became the 75%-plus controlling party of UKSR on 4 July 2025, the date Sognnes ceased. Chris Williams was registered as a person with significant control of the UK holding company on the same day.

Diamond and Williams each hold >25% and ≤50% of the UK holding company, per its persons with significant control register. Glomar has not disclosed its outside investors.

The public description and the register do not fully align. The website presents the UK companies as subsidiaries of the Delaware corporation, Companies House records only the two individuals as controlling parties, and the audited accounts name Minerals Harvesting Glomar LP as ultimate parent. Read together, the partnership sits at the top and the Delaware company is the operating face in Washington.

Listed exposure

There is no Glomar Minerals ticker. The only listed exposure to the venture is Cobalt Blue Holdings Limited (ASX: COB), the Project Infinity partner. Its other asset is the Broken Hill Cobalt Project, so the shares are not a pure read on Glomar.

Presentations

Glomar publishes no investor presentation. The nearest current deck is from its Project Infinity partner, Cobalt Blue Holdings, covering the processing side of the venture.
