BARISAN Gold is drilling a new deep hole at the Upper Tengkereng porphyry prospect of its Barisan Gold-Copper Project in Aceh province, North Sumatra. Based on the drilling rate of the company’s two previous deep holes, this hole is expected to reach the 750 metre mark during the first week of March.
After an internal review the hole was slightly adjusted before drilling started in late January. It is now being drilled with an azimuth of 55 degrees and an inclination of 78 degrees. The steeper incline is to align the depths where it is anticipated the new hole will intersect the high grade zone identified at the bottom of a previous hole drilled by the project’s previous owner.
The final 59 metres of the previous hole intersected 1.2 grams/tonne gold and 0.5% copper – the highest grade intercept longer than 50 metres returned at Upper Tengkereng so far.
The drill pad for the new hole is 200 metres down hole of the previous hole’s pad in a north-easterly direction. The steeper incline is required in order to reach the same depth in the same general area of the high grade zone. The new hole was expected to reach the high-grade zone intersected in the previous hole at about the 520 metre mark in mid-February and is aimed at extending the zone at depth and in a northeast direction.
The new hole is planned to a minimum length of 750 metres and a maximum length of 1750 metres, depending on where the limestone contact zone is intersected or if it is not intersected, until mineralization is no longer intersected.
Barisan completed another hole at Upper Tengkereng 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 Barisan’s three previous holes, it was fully mineralized, intersecting porphyry mineralization six metres from surface all the way to the end of the hole with only a narrow 82 metre barren zone towards the top of the hole.
Despite being drilled away from the high grade zone mentioned above, this hole returned 30 metres from 320 metres @ 1.2 grams/tonne gold and 0.4% copper, and 202 metres @ 0.7 grams/tonne gold, 0.4% copper and 0.01% molybdenum.
Barisan Gold is a Canadian-based minerals exploration company listed on the TSX Venture Exchange and engaged in the exploration, acquisition and development of mineral properties in Indonesia. It currently owns and operates two gold and gold-copper properties in Aceh province - the Barisan gold-copper porphyry belt and Abong epithermal gold project.
