A mineral highly wanted and with a great commercial value.Annually Brazil produces about 30 tons of gold. This number put the country among the biggest producers in the world.

Mar 27, 1998 Gold deposits have been found in Indonesia and Papua New Guinea, as well as in the tropical forests north and south of the Amazon River. The resulting Amazon gold rush has brought as many as a half million transient miners (garimpeireos) equipped with picks, shovels, and sluice boxes to search for the mineral in alluvial deposits.Brazil’s annual production peaked in 1987 at nearly 90 tons.
The northern portion of the property lies within the western extension of the Tapajpos River Gold Belt, immediately west of historic gold production where gold was first documented in 1747. Gold production peaked during 1983-89 when than 300,000 garimpeiros working alluvial deposits produced one million ounces per year.
