Key facts and history

In 1995, RTZ and CRA merged into a dual listed company, and RTZ became Rio Tinto plc while CRA became Rio Tinto Limited.[2] Mining activities for copper, silver, gold, and other minerals have occurred since ancient times at a location on the Río Tinto in Huelva, Spain.[3] Between 1877 and 1891, the Río Tinto Mine was the top copper producer globally.[4] Rio Tinto finalized its biggest acquisition ever on 14 November 2007, buying the Canadian aluminum company Alcan for $38.1 billion.[5]

To enlarge the Brockman 4 mine in May 2020, Rio Tinto destroyed a sacred Aboriginal site in Juukan Gorge, Western Australia, a location showing signs of continuous human habitation for 46,000 years.[6]

What the cited sources add

Harvey's 1981 economic history of the company states that the group won the Spanish mine auction on 14 February 1873 with a bid of £3.68 million.[7][8] A BBC News article from 8 November 2007 reports that BHP Billiton made a bid approach for Rio Tinto, and that Rio Tinto shares rose 27% on the news.[9] According to the same source, the winning bid included a condition that Spain would forever give up any claim to royalties from the mine's output.[7][8] A 2020 work by Matteo Millan and Alessandro Saluppo recounts that on 4 February 1888, thousands of ordinary workers marched to the Río Tinto town hall to present their requests to the mayor.[10][11][12]
