Barisan Gold provides drilling update at Upper Tengkereng

Vancouver-based Barisan Gold Corporation provided Tuesday an update on drilling activities at its Upper Tengkereng porphyry prospect, located in the Province of Aceh, as follows.
Barisan Gold commenced drilling of Hole UTD-005 on January 29, 2014. Hole UTD-005 is being drilled with an azimuth of 55 degrees and an inclination of 78 degrees.
As of February 28, 2014, drilling had reached 836 meters in length, ahead of the schedule provided in the January 29, 2014 press release. Although no assays have yet to be received on UTD-005, Barisan Gold is extremely satisfied with the results to date.
?UTD-005 has so far matched our geological model for the eastern part of the Upper Tengkereng prospect, hence increasing our confidence of the geological continuity at Upper Tengkereng,? the company said in a statement.
Furthermore, the higher-grade zone forecast to be intersected from 525-675 meters seems to have been extended further to the current depth of 836 meters and seems to continue at depth. High-resolution pictures of the tray cores for the higher-grade zone between 542-762 meters.
The following table presents the visual interpretation of UTD-005 up to the 836-meter mark.
| Length | Rock Type | Mineralization (Visual Interpretation Only) |
| 0 - 5 m | Soil | - - |
| 5 - 74 m | Advanced Argillic-Argillic, Hydro Breccia | Chalcocite: 0.2-0.3%, Chalcopyrite: 0.2-0.3% |
| 74 - 82 m | Argillic, Hornblende Feldspar Porphyry | Chalcopyrite: 0.3% |
| 82 - 125 m | Argillic, Hydro Breccia | Chalcopyrite: 0.2% |
| 125 - 259 m | Propylitic, Hornblende Diorite | - - |
| 259 - 268 m | Advanced Argillic-Argillic, Hydro Breccia | Chalcocite: 0.1%, Chalcopyrite: 0.1% |
| 268 - 304 m | Argillic, Hornblende Feldspar Porphyry | Chalcopyrite: 0.1-0.4% |
| 304 - 324 m | Advanced Argillic-Argillic, Feldspar Porphyry | Chalcocite: 0.3% |
| 324 - 342 m | Advanced Argillic-Argillic, Hornblende Feldspar Porphyry | Chalcocite: 0.1%, Chalcopyrite: 0.2% |
| 342 - 378 m | Phyllic, Feldspar Porphyry | Chalcocite: 0.3-0.4% |
| 378 - 430 m | Phyllic, Hornblende Feldspar Porphyry | Chalcocite: 0.2% |
| 430 - 453 m | Phyllic-Argillic, Feldspar Porphyry/Hydro Breccia | Chalcocite: 0.2-0.3%, Chalcopyrite: 0.2-0.3% |
| 453 - 471 m | Advanced Argillic-Phyllic, Feldspar Porphyry | Chalcocite: 0.3-1.0%, Chalcopyrite: 0.3-0.5% |
| 471 - 526 m | Argillic-Phyllic, Feldspar Porphyry | Chalcocite: 0.3-0.5%, Chalcopyrite: 0.3-1.0% |
| 638 - 710 m | Chlorite-Sericite/Potassic, Feldspar Porphyry | Chalcocite: 0.3%, Chalcopyrite: 1.5-2.0% |
| 710 - 836 m | Chlorite-Sericite/Potassic, Equigranular Diorite | Chalcopyrite: 0.6-2.0% |
In addition, UTD-005 has yet to intersect any limestone contact zone, which we predicted would be intersected at the 750-metre mark if it had been vertically dipping. This means that the limestone contact zone is either diagonally dipping away from the deposit or horizontally lying closer to surface.
Although UTD-005 was planned to a final length of 750 meters, Barisan Gold intends on pursuing UTD-005 until the earlier of (i) hitting the limestone contact zone, (ii) drilling out of porphyry mineralization and (iii) reaching the design capacity of the rig, which is 1,750 meters.
In other news, Barisan Gold has received the final assays for UTD-004. There were no new meaningful higher-grade intercepts in the final section from 986 to 1,465 meters. UTD-004 ended up with 1,459 meters of 0.3g/t gold + 0.2% copper, including 30 meters of 1.2g/t gold + 0.4% copper and 202 meters of 0.7g/t gold + 0.4% copper + 0.01% molybdenum. UTD-004 was fully mineralized 6 meters from surface until the end of the hole at 1,465 meters.
