Native American group seeks to overturn US court ruling on Rio's Arizona copper mine

A Native American group has asked all members of a US appeals court on Monday to overturn an earlier ruling that granted land to Rio Tinto for a copper mine in Arizona, saying the land was sacred and culturally significant. A ruling from a smaller group of the San Francisco-based 9th US Circuit Court of Appeals had earlier this month ruled that the federal government may give away thousands of acres in US state Arizona to Rio Tinto and minority partner BHP for the Resolution Copper project.
