Barisan Gold Corporation is mobilizing a second drill rig to its Upper Tengkereng gold-copper porphyry discovery, in Aceh province of northern Sumatra. This will enable the company to accelerate the drill program after receiving successful drill results from the first five holes.

The second rig will test the numerous high-grade zones intersected to date as well as test a number soil geochemistry anomalies identified during surface mapping and sampling programs. In addition, the second drill rig will also test the large limestone cover lying to the east and north of the mineral intrusive for potential high grade copper-gold skarn mineralization and the hydrothermal breccia cover lying to the south of the diorite footprint.

“Bringing in a second rig allows us to accelerate the discovery and delineation of the Upper Tengkereng porphyry prospect,” says Barisan’s CEO Alex Granger. “As we are drilling deep holes of up to 1750 metres depth at Upper Tengkereng, each hole is taking about two months to complete.

“By adding a second rig, we will increase our production rate to one hole completed every month, accelerating the definition of the mineralization and disclosure of assays. We anticipate a significant decrease in our already low drilling costs per metre as the addition of the second rig requires no additional fixed overhead costs and very limited additional flexible costs.”

PT Indodrill Indonesia, the current drilling operator at Upper Tengkereng, is moving a second rig to site, which has the same 1750 metre capacity as the current rig. The rig is scheduled to arrive in the next two weeks and will immediately be put to use.

Barisan Gold has started prepping a new drill pad location where the second rig will begin drilling. The pad is across the highway drilling back in the opposite direction of two holes drilled on the same axis. The objective is to scissor cut the high-grade zone identified in the two previous holes (190 metres of 1.3 grams/tonne gold and 0.6% copper) and to attempt to determine the true shallowness and true depth of the high-grade zone.

Work continues on the mapping and sampling program of the limestone cover to the east and north of the mineral intrusive. Once the campaign is completed and results are compiled, it is expected that one of the two rigs will be moved to a new drill pad to be located atop the limestone to start drilling high probability skarn prospects. Drilling atop the limestone should begin in two to three months.
