The first batch of drill results received by Barisan Gold Corporation for a hole at its Upper Tengkereng porphyry prospect in Aceh Province of Northern Sumatra has provided encouragement. The hole was completed on January 8 at a final length of 1465 metres, making it the longest and deepest hole ever drilled at the Barisan porphyry prospects. 
Similar to the three previous holes, the hole was fully mineralized, intercepting porphyry mineralization six metres from surface all the way to the end of the hole, with only a narrow 82 metre barren zone intercepted towards the top of the hole, compared with two barren zones for a combined 158 metres in the previous hole. As a result, the porphyry system remains open in all directions as well as at depth after the first four holes.
Assays have been received for the first 986 metres of the latest hole. Despite being drilled away from the high-grade zone identified in two previous holes, the new hole returned two intersections that include similar high grades to those in the two previous holes.
From 320 metres, it returned 30 metres @ 1.2 grams/tonne gold and 0.4% copper, similar to the 1.2 grams/tonne and 0.5% copper intersected from 638 metres in the first of the previous two holes. The latest intersection is 40 metres to the southwest and 300 metres shallower than the previous intersection, hence widening the potential shell of that high-grade zone both horizontally and vertically.
Deeper down hole, from 664 metres, the latest hole returned 202 metres at 0.7 grams/tonne gold, 0.4% copper and 0.01% molybdenum. This 202-metre long continuous high-grade zone is 185 metres to the east and 200 metres deeper than the high-grade zone of the two previous holes, potentially extending that zone on an east-west and depth basis.
“We are very pleased with the first batch of results received,” says Barisan’s CEO Alex Granger. “Although we were drilling away from the high grade zone identified in the last two holes, we still managed to intercept two similar high grade zones, including one zone that is 202 metres wide at the 664 metre level, the second widest high grade zone intersected in the deposit so far. The results appear to indicate that the high grade zone is going much further to the west than our geological models predicted.”
On December 24 Barisan completed construction of the new 130-metre road to the new drilling area on time and below budget, allowing for the construction of the next drill pad. The new drill pad is now ready to receive for set up the rig as soon as de-commissioning of the recent hole is complete. The transition between drill pads is expected to take about two weeks.
The next hole is designed to test the north-eastern boundary of the high-grade zone and will also be testing the limestone contact zone identified at surface, located northeast of the diorite footprint.
