The Iron Quadrangle

The Iron Quadrangle has been an area of mineral exploration dating back to the 16^th century. The discovery in 1699-1701 of gold contaminated with iron and platinum-group metals in the southeastern corner of the Iron Quadrangle gave rise to the name of the town Ouro Preto (Black Gold). The Iron Quadrangle contains world-class multi-million-ounce gold deposits such as Morro Velho, Cuiabá and São Bento. Jaguar holds the third largest gold land position in the Iron Quadrangle with over 50,000 hectares.
