Jacobina zones shaping up for Desert Sun (June 02, 2003)

Drilling by Desert Sun Mining (DSM-V) at the Jacobina project in Bahia state, Brazil, has established potential for a near-surface gold deposit.

Desert Sun recently drilled 12 holes at the Serra do Corrego prospect, about 2 km north of the Jacobina mill site. The results confirmed those of earlier drilling, which suggested a 30-to-40-metre-wide zone grading 1-1.3 grams gold per tonne.

Assays for only five of the recent holes were available at presstime, and five intersected mineralization over true widths of 25.7-34.8 metres. The average gold grades ranged from 0.4 to 1.4 grams per tonne. A sixth hole cut a narrower intersection, with a true width of 7.1 metres but with comparable grades, averaging 1.2 grams per tonne. Most of those intersections included narrower intervals of slightly higher-grade material, typically 3-7 metres in true width.

The drilling has defined a zone about 900 metres long, tested to a depth of no more than 100 metres.

Some previously drilled holes are also being re-sampled, as earlier operators sometimes restricted their sampling to visually detectable mineralized zones. Results from re-sampling of one old hole, SCO-71, indicate a grade of 1.5 grams gold per tonne over a true width of 34.9 metres, compared with an earlier result of 0.9 gram through the same interval. A second interval in the same hole, 3.1 metres wide, returned a grade of 2 grams per tonne, compared with 0.2 gram in previous sampling.

Core from six more holes on Serra do Corrego is now in the lab.

A program of 4,000 metres of drilling in 29 holes on the Morro do Vento prospect, 1.5 km south of the Jacobina mill, is just under way.

Meanwhile, induced-polarization surveys are testing areas with known gold mineralization to establish the response of mineralized rocks.
