While Rio has said it is not planning major acquisitions this year, the company will focus expanding its iron ore and copper businesses, its two largest divisions.For Walsh, the most obvious and significant growth opportunities for Rio are in the red metal sector. He told WSJ.com the company has high expectations for its Resolution project in Arizona, which has the potential to become North America's largest copper mine. He added Rio looks forward to proceeding with the underground development of Oyu Tolgoi in Mongolia. Other expansion opportunities include the La Granja project in Peru and a planned bauxite operation in Australia's Queensland state.According to data from Wyoming Geological Survey, the state accounts for almost 40% of all the US coal production.
