Sept 29 (Reuters) – The Metals Company said on Tuesday it has appointed former ExxonMobil upstream chief Liam Mallon to ​its board as the company advances ‌plans to begin commercial recovery of polymetallic nodules in international waters under a U.S. seabed mining framework.

Here are a few details

• The move comes ‌as ​the Trump administration signaled it ⁠is nearing approval ⁠for permits to mine the deep sea, part of a broader push to boost U.S. access to the critical minerals used ​across much of the country’s economy.

• The miner in 2025 had asked the ⁠Trump administration to approve ⁠its plans to mine the ​international seabed, making it the first such company ​to seek the government’s permission to operate ‌outside U.S. territorial waters.

• Mallon, who retired last year after a 35-year career at Exxon, will also chair TMC’s Sustainability and ⁠Innovation Committee.

• The company also said board member Brendan May would step down after two years ⁠on the ‌board.

• Exxon along with peers ⁠Occidental Petroleum and Equinor are ​increasingly ‌investing in lithium projects.

• Exxon is ​developing lithium ⁠production from brine resources in Arkansas to supply the electric vehicle battery market as part of its broader push into critical minerals.
