Arc updates drilling results at Trenggalek gold project

Australia-listed firm Arc Exploration Limited has received the results of a further four holes drilled at its Trenggalek Project in East Java. The program at Trenggalek is testing a number of areas that have the potential to prove up new gold resources.

Three holes drilled on the Timahan Prospect (TRDD050, TRDD052 & TRDD053) have tested two linear zones of surface gold mineralization hosted in silicified limestone (jasperoid) on the eastern side of the prospect. Shallow trenching over these two zones produced up to 28 m at 0.29 g/t gold and 13 m at 0.74 g/t gold from continuous-chip samples taken across the silicified outcrops.

TRDD050 and TRDD052 are located about 250 m apart along the Macan Zone. These holes returned down-hole intercepts of 1.5 m at 0.18 g/t gold from 72.5 m in TRDD050 and 10.25 m at 0.21 g/t gold from 13.25 m in TRDD052.

TRDD053 was drilled about 500 m south of TRDD048 along the Genteng Zone, which lies about 300 m east of Macan. TRDD053 returned a down-hole intercept of 13 m at 0.23 g/t gold from 4.6 m.

These initial holes confirm low-grade disseminated gold mineralization in silicified limestone (?jasperoid?) that is coincident with elevated arsenic and antimony. The holes have only tested a small part of the large silica capping at Timahan and may comprise a halo of low-grade gold adjacent to higher grade feeder structures.

TRDD051 was drilled at the Kojan Prospect at the very southern end of the Kenong Vein. The hole returned a down-hole intercept of 6.5 m at 0.17 g/t gold and 1 g/t silver from 126.0 m and is located about 50 m further south along strike from TRDD049. Both these holes are about 50 m away from TRDD035, which previously returned a strong down-hole intersection of 1.9 m at 11.28 g/t gold & 293 g/t silver.

The latest results at Kojan indicate the Kenong vein has pinched at its southern end and potential for an ore shoot in this part of the vein has been downgraded.

A summary of drill-hole details and mineralised intercepts is attached below.

Managing Director, John Carlile, commented: ?The initial drilling results from Timahan are low grade but confirm the presence of gold on the edge of the large 4-km2 silica capping that is anomalous in gold, arsenic and antimony. These latest holes indicate the upper levels of an epithermal system that has potential to host gold veins at depth. We plan to do more surface work before further drilling.

The southern limit of the Kenong vein seems to have been defined. Kenong is part of a multiple vein system at Kojan and areas of high-grade vein float to the north and east are currently being evaluated by test-pitting to guide further drilling.

We now plan to drill some more holes at Sentul at the southern end of the IUP to further test this large and open vein system.? (romel)
