08:48 AM EDT, 09/19/2025 (MT Newswires) -- Rio Tinto (RIO) and other companies have received informal notice from Glencore that it is open to selling a stake in its copper mine in Congo, Bloomberg News reported Friday, citing people familiar with the matter.

Glencore's assets in the Congo include Kamoto Copper, a partnership with Gecamines and the Congolese government.

The report said that Glencore has held talks with potential bidders for the mine, including Orion Resource Partners, which had previously approached the London-listed miner with a proposal for the New York fund to buy the Congolese project through its joint venture with Abu Dhabi's ADQ.

A potential sale of the mine has been discussed as part of talks between the US and Congo over a minerals and infrastructure partnership, the report added.

Glencore and Orion Resource Partners declined to comment, while Rio Tinto did not immediately respond to request for comment from MT Newswires.
