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.
