Rio Tinto has been named the official metal provider for the 4,700 medals which will be awarded at the London 2012 Olympic and Paralympic Games.
The mining giant's Kennecott Utah Copper mine in Utah, US, and its Oyu Tolgoi mine in Mongolia, which will go into commercial production next year, will produce the metal for the medals.
Rio Tinto chief executive Tom Albanese said the company set out its ethical track record to support its role as the official metal provider for the games.
"We have rigorous standards for air quality, ecosystems, biodiversity, climate change, the use of energy, land and water, and waste disposal. Before we even open a mine we plan for its closure and how to restore the land," said Albanese.
"We support London 2012's commitment to delivering the most sustainable games ever. It aligns with Rio Tinto's commitment to sustainable development wherever we operate."
