Rio Tinto plans to move some of its London-based support staff as it forms three global hubs, as well as a commercial and marketing hub in Singapore, Reuters reported Feb. 22.

The company has started consultations with the workers, as some roles are expected to be moved to one of the three hubs.

The miner, which is listed in Australia and the U.K., said it was not changing the company's operating model.

Rio Tinto said via an email that it was "adjusting where work is done by creating three global hubs," but did not specify the locations.

CEO Jean-Sébastien Jacques earlier said that the miner is "comfortable" with its existing dual-listing structure. The comments came amid pressure on fellow mining giant BHP Billiton Group by activist shareholder Elliott Management to simplify its corporate structure.
