Deep Sea Minerals Corp proposes deep‑sea nickel mining to meet US defense needs

Deep Sea Minerals Corp (ticker A420P7) submitted a formal proposal to the U.S. Defense Industrial Base Consortium on 20 March 2026, seeking a domestic source of defense‑critical nickel and a complementary commercialisation facility. The company plans to obtain the metal from polymetallic nodules located in the Clarion‑Clipperton Zone on the ocean floor.

Nickel supplies are currently dominated by Indonesia, which produces about 60 % of the world’s nickel, while Chinese firms control roughly 65 % of Indonesia’s refining capacity. Deep Sea Minerals Corp argues that harvesting nodules from the seabed could reduce the environmental footprint compared with traditional land mining, which involves extensive drilling, blasting and waste disposal. The firm acknowledges that seabed disturbance is real and that deep‑sea ecosystems may take decades to recover.
