PNG PM Marape rejects deep-sea mining even as provincial authorities try to revive project

 

• Papua New Guinea’s prime minister, James Marape, opposes deep-sea mining in Papua New Guinea, according to comments made at the United Nations Ocean Conference and directly to Mongabay.
• Contradicting his position, however, is the governor of PNG’s New Ireland province, Walter Schnaubelt, who has vocally supported mining the Solwara 1 project and reportedly met with company and national government officials about extracting copper and gold from the seabed.
• From early on, the project has faced opposition from coastal communities living near the Solwara 1 site who are concerned about the impacts of mining on seafloor ecosystems and the fisheries on which they rely. In February 2025, they formally requested a forum to voice their grievances and hear responses from the companies involved, but have yet to receive a response, they say.
• The company originally awarded the mining license went bankrupt in 2019, and other companies have since tried to resuscitate the project, but without consulting communities or informing them of the risks associated with deep-sea mining, according to the communities. In July 2024, the companies carried out trial mining; government officials say they were unaware of the ship’s presence, but internal documents and emails suggest that key leaders were likely aware that trial mining was planned as early as 2022.

NICE, France — James Marape, the prime minister of Papua New Guinea, voiced his government’s rejection of seabed mining at the 2025 United Nations Ocean Conference that took place between June 9 and 13, in Nice, France. His position stands in sharp contrast to the situation unfolding in the country’s New Ireland province, where local authorities are paving the way for foreign companies to begin mining the seabed, despite long-standing, community-led opposition to these developments.

“As a country, we don’t want any deep-sea mining in Papua New Guinea,” Marape told Mongabay in an exclusive interview on the sidelines of the U.N. Ocean Conference (UNOC) on June 10. He said his country would uphold its moratoria against the industry — one of which was announced in 2019, and another in 2023.

The main reason for this position, he said, is that the seas around Papua New Guinea (PNG) are “sensitive and fragile” and are home to important fisheries. “Our waters are very fertile in as far as marine life is concerned,” he said, adding that scientific evidence on how mining might affect marine ecosystems is scant. A recent brief from the U.N. secretary-general’s scientific advisory board warns of “irreversible” potential impacts on sea life due to the destruction of seafloor habitat, sediment plumes and the release of toxins by deep-sea mining.

While Marape publicly asserted his opposition to the nascent industry, a proposed project to dig up copper and gold at a site known as Solwara 1 off the coast of New Ireland province in northeastern PNG appears to be moving ahead after years of dormancy, despite community opposition.
