Project Details


On its 20,000ha site, the Andorinhas mine has two concessions, Mamão and Lagoa Seca, which have exploration and development information dating back to the middle of the twentieth century.
Large-scale production began at the mine in 2008 with an initial investment of around US$15.5mn. Since its startup until 2013 the mine has produced an average of 50,000oz/y of gold. It has a mineral recovery capacity of 92%. During the exploration stage, Troy Resources drilled more than 44,000m at Andorinhas, detecting deposits of gold of 46.4g/t-340g/t.
