BRAZIL Crushing and agglomeration began last week at the Fazenda Nova mine in the Goias state. The project is operated by YAMANA GOLD of Toronto. Loading of the heaps is to begin this week, and the first gold pour is scheduled for this fall.
The Fazenda Nova mine is located about 300 km from the national capital of Brasilia. The deposit contains at least six shallow, blanket-like zones in saprolite. One of these, the Lavrinha zone, is up to 50 metres thick and covers an area 3 km by 1 km. The mine is a shallow open pit heap leach mine with three initial pits to a depth of 50 to 60 metres in ore.
Yamana has invested almost US$6.6 million to build an operation that will produce an estimated 143,000 oz of gold during its first four years. The recovery rate is estimated at 88% based on a 90-day leaching cycle.
This is the second gold mine for Yamana. It also runs the 100,000-oz/year Fazenda Brasileiro mine. For details, go to www.yamana.com.
