Overview

  • The Metals Company submitted the first-ever application to commercially mine polymetallic nodules in international waters, triggering a six-month review by NOAA.
  • At the 30th International Seabed Authority session, 37 governments formally called for a moratorium on commercial deep-sea mining to protect fragile ocean ecosystems.
  • ISA Council leadership is under pressure to finalize a Mining Code by year-end, a move opposed by environmental groups and some member states fearing irreversible damage.
  • President Trump’s April executive order directed agencies to fast-track seabed mining claims, framing critical minerals as a national security imperative to counter China.
  • Scientists warn that small-scale deep-sea mining tests from the 1980s still show no microbial recovery after 26 years, underscoring long-term environmental concerns.
