Rio Tinto is a leading international mining group headquartered in the UK, combining Rio Tinto plc, a London and New York Stock Exchange-listed company, and Rio Tinto Ltd, listed on the Australian Securities Exchange.

According to Indigenisation minister Saviour Kasukuwere, Murowa is soon expected to relinquish majority shareholding to Zimbabwean locals in line with the country’s economic empowerment legislation.
According to media reports, Rio Tinto plans to cede 29% of its stake in the diamond mine to Zimbabwean locals, where 10% would be transferred to a community share ownership trust, another 10% to employees while the balance will be given to the National Indigenisation and Economic Empowerment Fund.
