Members of a U.N. agency that governs international waters are locked in a fierce debate amid disagreement over whether to allow deep sea mining and set a new deadline for proposed regulations still stuck in draft mode

SAN JUAN, Puerto Rico — Members of a U.N. agency that governs international waters were locked in a fierce debate late Friday over whether to allow deep sea mining and set a new deadline for proposed regulations still stuck in draft mode.

The U.N. International Seabed Authority, which is based in Jamaica, began its two-week conference on the issue July 10 but discussions behind closed doors dragged on during the last day of the meeting.

“It’s quite a marathon,” Michael Lodge, the agency’s secretary general, said at a press briefing Friday. “There are still loose ends to tie up.”

The agency has yet to issue any provisional mining licenses, and it missed a July 9 deadline to approve a set of rules to govern such activity.

Companies and countries can now apply for a mining license as demand surges for precious metals that are found in the deep sea and are used in electric car batteries and other green technology.

The U.N. agency has issued more than 30 exploration licenses but none for actual mining so far. Most of the exploration is focused in an area between Hawaii and Mexico that spans some 1.7 million square miles (4.5 million square kilometers), with the activity taking place at depths of up to 19,000 feet (6,000 meters).

Members of the International Seabed Authority said they expect to resume work on the proposed regulatory framework at the body's November meeting, the third one of the year.
