BRAZIL – Toronto-based YAMANA GOLD has started up the mill at its Chapada copper-gold mine 270 km northwest of Brasilia. Final checks of the SAG and ball mills, flotation, thickening and filtration circuits as well as the utility systems should be completed by the end of October.

The stockpile has reached 1.8 million t, and open pit mining is underway at a rate of 60,000 t/d.

Yamana (www.Yamana.com) expects to begin delivery of copper and gold concentrate in November. The project will produce approximately 2.0 billion lb of copper and 1.3 million oz of gold over the next 19 years. Cash costs on a coproduct basis were estimated in 2004 to be US$140/oz for first five years and US$185/oz life of mine for gold, and US$0.57/lb for first five years and US$0.68/lb life of mine for copper.
