The final drilling done by Barrick Exploration indicated 64 metres of copper mineralisation at 0.59% copper from 141m depth, including 10.2m at 1.59% copper.

Another intersection of 4.9m grading 13.6% zinc, 0.85% copper, 0.41 grams per tonne gold and 24.03gpt silver was found at a depth of 290.1m.

The copper mineralisation encountered in this hole is more than 100m west of that encountered in the first two drillholes which were completed in 2008 by Coppermoly.

These holes intersected 54m of 1.22% copper from 30.3m and 73m grading 0.96% copper from 36m.

Coppermoly managing director Peter Swiriduik says the potential for more finds in the Nakru tenement is pleasing.

"There are more large areas of untested anomalous copper and zinc geochemistry throughout the Nakru tenement that provide a lot of scope for additional discoveries," he said.

Coppermoly also announced on Tuesday that geophysical induced polarisation surveys had commenced on the Nakru project.

These are hoped to define additional copper sulfide targets like those found at Nakru-1 and Nakru-2.

Meanwhile, Barrick is drilling a sixth diamond drillhole at Nakru-1.
