Deep Sea Minerals’ Nasdaq move: strategic signals for subsea mining planners

30 Second Briefing
Deep Sea Minerals (CSE: SEAS) has applied to uplist to the Nasdaq, which would make it the third seabed exploration company on the exchange alongside The Metals Company (Nasdaq: TMC) and Odyssey Marine Exploration (Nasdaq: OMEX), pushing its share price to a record C$1.79 and valuing it at just over C$80 million. The Vancouver-based firm currently has no active projects but is targeting polymetallic nodule concessions in the 4.5‑million‑sq‑km Clarion–Clipperton Zone (3,500–6,000 m water depth) and the Cook Islands EEZ, where nodules are estimated at 21 billion tonnes and 6.7 billion tonnes respectively. For mining strategists, the move signals another capital-markets vehicle positioning early for potential future access to large-scale subsea nickel, cobalt, copper and manganese resources pending regulatory pathways in the Pacific.
Technical Brief
- Clarion–Clipperton Zone target area spans ~4.5 million km² of abyssal plain between Hawaii and Mexico.
- USGS estimates ≥21 billion tonnes of polymetallic nodules on the CCZ seafloor at 3,500–6,000 m depth.
- TMC’s recently approved NOAA licence reportedly covers ~1 billion tonnes, a small fraction of CCZ inventory.
- Cook Islands EEZ nodule endowment is estimated at 6.7 billion tonnes in a US Congress study.
- Deep Sea Minerals is only at “early engagement” stage with Pacific governments and regulators on concession pathways.
- CCZ nodules are described as “potato-sized” clasts enriched in Ni, Co, Cu and Mn, suited to bulk-collection systems.
Our Take
Deep Sea Minerals’ move to Nasdaq follows its oversubscribed C$4.22 million raise and licence applications in the Clarion–Clipperton Zone and Cook Islands EEZ noted in our April 2026 coverage, signalling a deliberate push to match TMC’s capital-markets profile as both chase polymetallic nodules in overlapping Pacific jurisdictions.
In our database of 1202 Mining stories, only a small subset of battery metals and critical minerals pieces involve US NOAA and DSHMRA licensing, so Deep Sea Minerals’ parallel US-facing applications and Nasdaq ambitions place it in the same emerging regulatory corridor as TMC’s recently certified USA B licence rather than in the more common land-based nickel or copper project pipeline.
