Desert Sun Mining (DSM-T) has revised the resource estimate at the Jacobina project in Bahia state, Brazil, following a drill program in 2004, converting a significant tonnage from inferred to measured and indicated resources.
The four main mineralized zones at Jacobina now have a measured and indicated resource of 18.3 million tonnes grading 2.8 grams gold per tonne, plus 26.2 million tonnes of inferred resources grading an average 2.5 grams per tonne.
The largest zone, Joao Belo, sports 12.6 million tonnes grading 2.4 grams gold per tonne in the measured and indicated categories. A further 5.3 million tonnes at 2.3 grams is inferred.
New gold zones discovered at the Morro do Vento prospect have increased the resource on the Itapicuru zone, which now has 4.1 million tonnes grading 3.6 grams per tonne in measured and indicated resources, plus 12.2 million tonnes grading 2 grams in inferred resources.
At Serra do Corrego, Desert Sun’s estimate was unchanged: a measured and indicated 920,000 tonnes grading 2.4 grams gold per tonne, with another 1.8 million tonnes of inferred resources at 3 grams per tonne. The Canavieiras zone’s resource is now estimated at 660,000 tonnes measured and indicated, grading 5.9 grams per tonne, and 4 million tonnes inferred, grading 3.6 grams.
Inferred estimates on other zones come to 2.9 million tonnes grading 3.3 grams gold per tonne.
