NOAA is weighing two applications from The Metals Co. to explore for minerals in international waters despite pushback from environmental groups and international regulators.

The Trump administration is formally vetting two applications from a Canadian mining company that wants to explore international waters for precious metals.

NOAA plans to hold virtual hearings later this month on two applications that a subsidiary of The Metals Co. submitted this summer, according to a Federal Register notice. The Vancouver-based company has said it hopes to begin commercial mining in a part of the Pacific Ocean dubbed the Clarion-Clipperton Zone in 2027.

President Donald Trump has prioritized deep-sea mining, a process through which mineral-rich nodules are extracted from the ocean floor. In April he signed an executive order calling for permits in both domestic and international waters.

It’s a prospect that has alarmed environmental groups concerned about damage to pristine seafloor habitats, and nearly 40 countries have called for a moratorium or ban on seabed mining.
