Trump Administration Advances First Offshore Critical Minerals Lease Sale Under New Marine Minerals Agency

July 17, 2026 — The Trump administration has taken another step toward launching a U.S. offshore critical minerals industry, with the newly created Marine Minerals Administration (MMA) releasing a proposed leasing notice that could lead to the first federal deep-sea mineral lease sale in U.S. waters.

The proposal covers federal waters off American Samoa and marks one of the first major regulatory actions by the MMA since the Trump administration announced plans in April to merge the Bureau of Ocean Energy Management (BOEM) and the Bureau of Safety and Environmental Enforcement (BSEE) into a single offshore regulator.

The proposed lease sale is part of the administration’s broader effort to secure domestic supplies of critical minerals—including nickel, cobalt, copper and manganese—that are widely used in batteries, defense systems and advanced manufacturing while reducing dependence on Chinese-controlled supply chains.

“Critical minerals have become a strategic asset in global competition, and China’s dominance in the supply of many of these materials creates unacceptable risks for America’s energy, defense and manufacturing sectors,” Acting MMA Director Matt Giacona said.

Deep-sea mining risks disrupting the marine food web, study warns

November 6, 2025 — Drilling for minerals deep in the ocean could have immense consequences for the tiny animals at the core of the vast marine food web — and ultimately affect fisheries and the food we find on our plates, according to a new study.

Deep-sea mining means drilling the seafloor for “polymetallic nodules” loaded with critical minerals including copper, iron, zinc and more. While not yet commercialized, nations are pursuing deep-sea operations amid rising demand for these minerals in electric vehicles and other parts of the energy transition, as well as for technology and military use.

The researchers examined water and waste gathered from a deep-sea mining trial in 2022.

What the study discovered

University of Hawaii researchers studied an area of the Pacific Ocean called the “twilight zone,” about 650-5,000 feet (200-1,500 meters) below sea level. Their peer-reviewed findings, published Thursday in the Nature Communications scientific journal, say mining waste could affect anything from tiny shrimp smaller than .08 inches (2 millimeters) long to fish 2 inches (5 centimeters) long.

That’s because, after mining companies bring the mineral-rich nodules up to the surface, they have to release excess sea water, ocean floor dirt and sediment back into the ocean. That creates a murky plume of particles about the same size as the naturally occurring food particles normally eaten by the zooplankton that swim at that depth.
