History1736 : Gold was firstly discovered by fugitives slaves1741: Gold “re-discovered” by a portuguese expedition that was lookingfor the fugitives slaves – foundation of Pilar de Goias1754 : Four thousand people living based on gold mining in Pilar1800’s: Declining of gold cicle : economy shift to agriculture1972 : First exploration works by Mineradora Montita1982 : Gold rush in the area by “Garimpeiros”1984: BHP/Montita tried restart exploration – no sucess1989: Declining of “Garimpos” : Inco/Montita restarted explorationworks, which were suspended in following year1990-2005 : Few exploration works conducted by Montita (Total historicaldrilling 5,000m)
