The U.S. government is considering investing in a company’s critical minerals mining projects in Greenland, its CEO has told CNBC, ahead of high-stakes talks between Washington and Danish officials over the island’s future.

The projects are run by mining company Amaroq

, which operates in South Greenland and is involved in extracting or exploring gold, copper, germanium and gallium, among other critical mineral deposits.

Discussions with U.S. government bodies about the potential investment opportunities are ongoing and haven’t been finalized, Amaroq CEO Eldur Olafsson told CNBC in an interview.

Deals could involve “offtake agreements, infrastructure support and credit lines,” Olafsson added, though he declined to comment on what specific projects the U.S. government was interested in.
