Overview

The Fazenda Brasileiro mine is located within the Maria Preta mining district in Baha State, Brazil, about 180 km northwest of the state capital city of Salvador. The mine covers approximately 63,400 ha, and is accessible by air and road. The Fazenda Brasileiro mine has a 30 year operating history and is primarily an underground operation being mined by conventional retreat longitudinal longhole open stoping with a carbon in pulp 1.3M tpa milling facility.

Geology and Mineralization

Fazenda Brasileiro is located within the Rio Itapicurú Greenstone Belt (RIGB), a 100 km long, 60 km wide north-south trending volcano-sedimentary belt situated within the São Francisco Craton. Fazenda Brasileiro is an epigenetic, structurally controlled, and hydrothermally altered Precambrian quartz vein hosted lode gold deposit that has been subjected to greenschist facies metamorphism. The main mineralization is in the form of sulphide-bearing quartz veining, and these multiple vein systems vary in true width from 1.5 m to 40 m and horizontal mining widths vary from a minimum 3 m to 40 m.
