Duas Barras Diamond Mine
Vaaldiam holds 100% interest in the Duas
Barras alluvial diamond mine, situated 150km north of the
historic town of Diamantina in the State of Minas Gerais,
Brazil. It is Brazil’s newest diamond mine and commenced
commercial production in September 2007. This diamond
district was the world’s largest diamond producing area
prior to 1870. The 171 hectare Duas Barras property
encompasses a 5km portion of the Jequitinhonha River. The
diamonds produced from alluvial gravels along the
Jequitinhonha River are predominantly gem-quality cuttable
goods.
The mine contains National Instrument

Prior to
the recent financial crisis the Duas Barras mine achieved
average rough diamond sales values of US$165 per carat.
Operating costs are expected to average US$85 per carat.
Exploration Potential: Vaaldiam is
actively negotiating to acquire additional properties in the
Duas Barras area, which have the potential to significantly
expand the volume and duration of diamond production.
