Rio Tinto (RIO) History

It was in 1873 when Rio Tinto was formed to facilitate the copper workings in a mine located at Rio Tinto in southern Spain. Formerly called The Rio Tinto-Zinc Corporation, RTC was the result of the merging between The Consolidated Zinc Corporation and The RTZ Corporation. At the same time, as a result of the merging between The Rio Tinto Company and The Consolidated Zinc Corporation, CRA was formed. It was between the years 1962 and 1995 when important mineral deposits were discovered by RTZ and CRA and these two companies developed major mining projects. These projects expanded through acquisition. It was in 1995 when a union of RTZ and CRA was made and finally in 1997, CRA Limited was transformed into Rion Tinto Limited and The RTZ Corporation was transformed into Rio Tinto plc. These two companies are known as the Rio Tinto US Holding Companies.

In 2002, the stake of the group in Coal & Allied was increased to 75.1%. In 2003, an agreement to sell the 20% interest of the group in the Sepon Project in Laos to Oxiana was signed by the group and this agreement for sale was finally completed in 2004. It was also in the same year when an agreement to allow the closer cooperation between Hamersley Iron and Robe iron ore operations in the Pilbara region of Western Australia was signed between the Rio Tinto and the Robe River Joint Venture Participants. Votorantim Metais bought Mineracao Serra da Fortaleza (MSF) in the same year. The sale for Rio Tinto shareholding in the Freeport-McMoRan Copper & Gold was also completed also in the same year.

All of these happened in the later part of 2004.

In November of the same year, a contract to sell the 14.5% shareholding in the Lihir Gold was entered into by Rio Tinto. This contract cost around $295 million.

In February 2006, the sale for the QIT-Fer et Titane proceeded. Approximately 26 million common shares were sold.
