US Offshore Critical Minerals Review Opens Virginia Seabed Mining Path

Bureau of Ocean Energy Management

US offshore critical minerals development has moved a step forward after the Bureau of Ocean Energy Management opened a request for information and interest covering a potential mineral lease area off Virginia. The review follows an unsolicited proposal from Odyssey Marine Exploration.

US offshore critical minerals activity could target heavy mineral sands, rare earth elements and phosphates across an approximately 1.8mn acre area off the Delmarva peninsula. The proposed zone covers about 7,160 km².

US offshore critical minerals policy is gaining strategic importance as Washington looks for new domestic sources of materials used in defence, electronics, energy and advanced manufacturing. However, the federal notice does not mean BOEM has approved a lease or commercial development.

Responses to the RFI are due by 23 July. The process will help determine industry interest, resource potential and whether the area should move toward a formal leasing stage.

Virginia Seabed Proposal Targets Rare Earths and Mineral Sands

Odyssey Marine Exploration submitted the original lease request in November. The company wants access to offshore mineral resources that could include rare earth-bearing heavy mineral sands and phosphate deposits.

Heavy mineral sands can contain several strategically important materials, depending on geology and mineral composition. Rare earth-bearing minerals are particularly important because the US is trying to reduce dependence on concentrated foreign processing and supply.

Phosphate resources could also add strategic value because phosphorus supports fertilizer production and food security. A multi-mineral offshore resource could therefore attract interest beyond conventional rare earth markets.

But commercial seabed mining remains technically and environmentally complex. Resource definition, extraction methods, permitting, marine ecosystems, processing routes and project economics will all determine whether offshore deposits can become viable supply.

The scale of the proposed area also means exploration would need to identify where commercially meaningful mineral concentrations actually exist. A large lease footprint alone does not guarantee an economic project.

Federal Policy Pushes Seabed Minerals Into Supply Strategy

The BOEM review follows a wider US policy shift toward seabed critical minerals. President Donald Trump signed an executive order in April 2025 aimed at accelerating seabed mineral exploration and commercial recovery permitting.

That policy reflects growing concern over critical mineral security. Washington is looking at domestic mines, recycling, processing, strategic reserves and now offshore resources as parallel supply options.

For the metals market, the significance is still long term. Even if a lease is eventually offered, exploration, permitting, environmental review and development could take years before material reaches commercial markets.

The strategic value lies in optionality. Offshore resources could eventually supplement terrestrial mining and provide another domestic source of rare earths and other critical minerals.

However, the project must still prove that seabed extraction can meet environmental, regulatory and cost requirements. That will be central to whether offshore mineral development becomes a meaningful part of US critical materials policy.

The Metalnomist Commentary

The Virginia review shows that the US is widening its critical minerals strategy from land-based mining to the seabed. The opportunity is significant, but offshore resources will only matter if geology, environmental approval and processing economics can align.
