Timeline
Rio Tinto is a combination of two companies: Rio Tinto plc, based in the UK, and Rio Tinto Limited, based in Australia. The British based Rio Tinto Company was formed by investors in 1873 to mine ancient copper workings at Rio Tinto near Huelva in southern Spain. The Consolidated Zinc Corporation was incorporated in 1905 to treat zinc bearing mine waste at Broken Hill, New South Wales, Australia.
The RTZ Corporation (formerly The Rio Tinto-Zinc Corporation) was formed in 1962 by the merger of The Rio Tinto Company and The Consolidated Zinc Corporation. CRA Limited (formerly Conzinc Riotinto of Australia Limited) was formed at the same time by a merger of the Australian interests of The Consolidated Zinc Corporation and The Rio Tinto Company.
RTZ and CRA were unified in December 1995. Directed by a common board of directors, the companies operate as a single entity even though they maintain separate shareholder lists in the UK and Australia. This places the shareholders of both companies in substantially the same position as if they held shares in a single enterprise owning all of the assets of both companies.
In June 1997, The RTZ Corporation became Rio Tinto plc and CRA Limited became Rio Tinto Limited, together known as the Rio Tinto Group. Rio Tinto plc is listed on the London and New York Stock Exchanges. Rio Tinto Limited is listed on the Australian Stock Exchange. Since the 1995 merger, the Group has continued to invest in developments and acquisitions in keeping with its strategy.
