Title

Deep Sea Mining Permitting Reform and Pacific Territory Opposition

Purpose

The House Natural Resources Subcommittee on Energy and Mineral Resources held this oversight hearing to examine regulatory and statutory barriers to deep sea mining, focusing on permitting reform following President Trump's April 2025 executive order on offshore critical minerals. Members and witnesses debated whether accelerating seabed mining would reduce US dependence on China for critical minerals, and Pacific territory representatives raised strong objections over inadequate consultation with American Samoa, Guam, and the Northern Mariana Islands.

Who spoke

Chairman Pete Stauber (R-MN)0:09:46: Argued deep sea mining is needed to reduce reliance on China, which he said dominates critical mineral supply chains0:09:46, citing USGS estimates of 21.1 billion dry tons of polymetallic nodules in the Clarion-Clipperton Zone0:10:40; later questioned Barron and Gunasekara on unsolicited lease requests near Guam0:53:32.

Ranking Member Yassamin Ansari (D-AZ)0:13:45: Said no commercial deep sea mining operation exists anywhere in the world and that The Metals Company has spent over $500 million while pushing its timeline back a decade0:14:15; cited American Samoa's unanimous territorial legislature vote against mining and 76,000 public comments opposing BOEM's first comment period0:14:43; noted a NOAA monitored test site has not recovered after 50 years0:15:58.

Rep. Jared Huffman (D-CA), Ranking Member, Full Committee0:18:03: Called deep sea mining "a solution in search of a problem," citing bankruptcies of Nautilus Minerals/Solwara One and Loki Marine Minerals0:19:17; pressed Barron on why vessel owners and processors are headquartered in Law of the Sea Treaty countries0:56:56 and got Barron to confirm no commercial deep sea mining operations exist anywhere0:54:08.

Chairman Bruce Westerman (R-AR), Full Committee0:23:00: Said China controls about 60% of global critical mineral production, 90% of processing, and 75% of manufacturing0:23:26; argued the US must responsibly develop seabed minerals or cede the market to adversarial nations0:24:41.

Mr. Gerard Barron, Chairman & CEO, The Metals Company0:26:30: Testified TMC USA submitted the first-ever commercial recovery permit application the day of the hearing0:29:03; proposed codifying NOAA's new consolidated permitting process, statutory time limits, and treating US-permitted minerals as domestic for tariff purposes0:30:17; confirmed under questioning that the company plans commercial production by end of 20270:55:04 and that its vessels would be US-flagged, outside Law of the Sea Treaty jurisdiction0:56:56.

Mr. Oliver Gunasekara, Co-Founder & CEO, Impossible Metals0:33:13: Said the World Bank forecasts more than a fourfold increase in critical mineral demand by 20500:34:08; described AI-driven robots that hover above the seabed and leave about 90% of nodules untouched0:35:52; said the industry could generate $300 billion in economic output and 100,000 jobs over a decade0:36:45; confirmed a voluntary 1% profit-share offer to American Samoa is not yet a binding commitment1:19:31.

Dr. Andrew Thaler, Founder & CEO, Blackbeard Biologic0:38:48: Said deep sea mining is really three distinct industries with different environmental impacts0:39:18; argued there is no current urgency for nodule mining given nickel/cobalt market surpluses and lack of US refining capacity0:40:03; said the abyssal plain is more biodiverse than tropical rainforests and species recovery remains depressed decades after mining0:40:530:41:20; testified he does not believe NOAA, BOEM, and BSEE currently have sufficient data to evaluate environmental impacts near American Samoa1:28:25.

Mr. Erik Milito, President, National Ocean Industries Association0:43:54: Displayed a polymetallic nodule and said dense fields can contain tens of thousands per square kilometer0:45:05; said BOEM has already issued regulations allowing critical mineral leasing and NOAA released a new modernizing rule the day before the hearing0:46:23; said "if this was a marathon, China is at mile 20 and we're just starting"0:48:59.

Rep. Jimmy Panetta / Mr. Case (D-HI)1:04:14: Pressed Barron on the tight timing between NOAA's rule release and TMC's permit filing, suggesting advance coordination1:04:41; argued the administration's actions may put the US in conflict with the international seabed moratorium and that China, by contrast, is abiding by the Law of the Sea Treaty1:08:37.

Rep. Paul Gosar (R-AZ)1:09:36: Asked witnesses about "micro concentrators" as a new ore-processing technology1:09:39; argued environmental restrictions on land mining pushed industry toward offshore alternatives1:11:34.

Rep. Raúl Grijalva (D-AZ)1:16:43: Said Arizona's tribal mining history shows what happens when indigenous voices are ignored1:16:43; pressed Gunasekara on whether American Samoans have received any binding commitments, and Barron/Thaler on realistic profit timelines, entering testimony from Pacific indigenous leaders into the record1:21:23.

Rep. Emily Randall / "Representative Dexter"1:27:19: Noted BOEM admitted the "presence of any mineable ore body is unknown" near American Samoa while proceeding with only an environmental assessment rather than a full EIS1:27:48; entered a New York Times article into the record reporting a TMC-funded study found small animal diversity fell over 30% in the path of a mining vehicle1:29:17.

Rep. Harriet Hageman (R-WY)1:33:04: Cited US import reliance of 100% for 12 critical minerals and over 50% for 29 others1:33:04; asked Barron and Gunasekara about processing challenges and Congress's role in supporting solutions1:36:32.

Rep. Nick Begich (R-AK)1:38:39: Noted only 52% of US coastal and ocean waters have been mapped and asked about accelerating mapping for national security1:39:06; noted Chinese vessels have been mapping seabeds near Alaska alongside Russia1:40:03.

Rep. Aumua Amata Coleman Radewagen (R-AS)1:44:50: Said the people of American Samoa are opposed to deep sea mining near the territory and asked for a minimum 50-mile mining buffer1:47:25; entered her RFI comments into the record.

Rep. Kimberlyn King-Hinds (R-MP)1:49:34: Said island communities "don't get the luxury of being wrong" because ocean decisions are permanent1:50:26; pressed Gunasekara for specifics on what permitting steps the industry wants shortened versus left untouched1:52:46.

Rep. James Moylan (R-Guam)1:54:59: Entered into the record Guam Legislature Resolution 13-238, Mayor's Council Resolution 26-01, a letter from Guam's elected officials, and a 5,000-signature coalition letter opposing deep sea mining1:56:28; asked Barron whether TMC's sediment plume claims have been independently reviewed1:58:11.

Rep. Jeff Crank (R-CO)1:59:59: Said China holds 5 of 22 international exploration leases, the most of any country2:00:20; asked Barron about US advantages in seabed mineral extraction and risks of Chinese market dumping2:03:14.

Key moments

Ansari and Huffman both noted no commercial deep sea mining operation exists anywhere in the world, and Barron confirmed this directly under questioning0:54:08.

Barron announced that morning TMC's plan to reach commercial production by the end of 2027, correcting Huffman's reference to a 2035 timeline0:55:04.

Case pressed Barron on the tight coordination between NOAA's new permitting rule (released the day before) and TMC's same-day commercial recovery permit filing, and Barron denied advance knowledge of the rule's contents1:04:411:05:36.

Case argued the US action may conflict with the International Seabed Authority framework, noting China is a Law of the Sea Treaty signatory and therefore cannot unilaterally mine international waters the way the US proposes1:08:37.

Moylan entered Guam Legislature Resolution 13-238, Mayor's Council Resolution 26-01, a letter from Guam's officials, and a 5,000-signature coalition letter — all opposing deep sea mining near the Marianas — into the hearing record1:56:28.

Thaler testified BOEM lacks sufficient baseline data to meaningfully evaluate environmental impacts near American Samoa, even as leasing proceeds via environmental assessment rather than a full EIS1:28:251:29:43.

Dexter entered a New York Times article into the record reporting a TMC-funded study found the number and diversity of small animals fell over 30% in the path of a mining vehicle, directly rebutting Barron's claims of fast ecosystem recovery1:29:17.

Barron confirmed TMC's mineral processing has so far occurred in Japan, with Korea Zinc recently becoming a shareholder to help build US processing facilities; no US site has been finalized1:23:091:24:04.

Gunasekara confirmed Impossible Metals' voluntary 1% profit-share offer to American Samoa is not yet a binding commitment1:19:311:20:01.

Gosar and Barron discussed "micro concentrator" ore-processing technology as a potential domestic alternative to sending unprocessed minerals to China for smelting1:09:361:10:08.
