==History==
In Chile the district was first officially recognized in 1975 and operated in 1979. El Indio, the main mine in the area was purchased by Barrick Chile in 1994; that mine is associated with a hydrothermal system of a volcanic caldera. In 1981 Compania Minera El Indio was the first company to exploit the area's mineral resource.〔(【引用サイトリンク】title=El Indio rejuvenated under Barrick Gold )〕
Chile's portion of the belt consisted of 3 major mines; El Indio, Pascua Lama, and Tambo (since 1995).〔(【引用サイトリンク】title=El Indio Belt Chile )〕 Gold reserves in the belt located within Argentina may be as high as 35 million ounces.〔
One of the largest mines in the belt, the Tambo Mine operated by Barrick Gold, closed in 2001 after attempts by the company to replace reserves proved unsuccessful. The mine, with a design capacity of 200,000 ounces a year was deplete of gold by 1999-2001.〔(【引用サイトリンク】title=Tambo Mine )〕
