Mining and resources group founded originally in 1873. The group is one of the world's largest mining companies, with a pre-tax profit of approximately 3.6 billion US dollars in 2004 on consolidated turnover of 14.1 billion USD.
Since 1995, Rio Tinto has been a
Dual Listed Company . Rio Tinto Limited, formerly known as CRA, is listed on the
Australian Stock Exchange , with Rio Tinto plc (formerly RTZ) listed on the
London Stock Exchange . The two companies are managed as a single economic unit by a unified board, with a share in either company entitling the owner to the same voting rights and dividend payouts. RTZ shareholders made up 76.7% of the new unified entity, which is primarily managed from London.
Its current
Chief Executive is
Leigh Clifford and the company board is chaired by
Paul Skinner .
Rio Tinto's origins are in southern Spain, at the site of an ancient mine which supplied the
Roman Empire . In 1873
N M Rothschild & Sons of
London and
De Rothschild Frères of
Paris joined with other investors to acquire the
Spanish government's money-losing Rio Tinto mines. The new owners restructured the company and turned it into a profitable business. By 1905, the Rothchild interest in Rio Tinto amounted to more than 30 percent.
In 1962 the (British) Rio Tinto Company acquired a majority stake in Consolidated Zinc, an Australian company, and was renamed the Rio Tinto-Zinc Corporation (RTZ). The Australian company was renamed Conzinc Riotinto of Australia (CRA) but retained a separate corporate identity, with an increasing proportion of its shares being held by the Australian public.
The current dual listed company structure was created in 1995.
