Arc: Drilling recommences at Trenggalek gold project

By Ruli Setiawan

ASX-listed gold miner Arc Exploration Limited announced Wednesday that drilling has recommenced on the Trenggalek Project in East Java with its joint venture partner, Anglo American, who are fully funding the program.

The drilling program has recommenced on a possible porphyry target identified at the Singgahan Prospect, located about 5-km east of Jerambah Prospect, where results obtained from the 1,022m diamond hole completed late last year were interpreted to indicate the weaker mineralised margins of a possible porphyry system, the company said in a statement.

This first hole at Singgahan will test part of a large coincident copper-gold-molybdenum anomaly highlighted in grid-soil and benching results obtained over an altered and quartz-magnetite-sulphide/limonite stockworked diorite intrusion. Initial benching results at Singgahan returned broad anomalous intercepts in weathered bedrock including 40m at 0.045 ppm Au, 386 ppm Cu & 4 ppm Mo and 100m at 0.063 ppm Au, 276 ppm Cu & 5 ppm Mo.

The large surface geochemical anomaly highlighted at Singgahan provides further encouragement for the possible existence of a porphyry system in the project area, which will be tested in the current phase of drilling.

Drilling started several days ago at the Singgahan Prospect, where recently reported soil sampling and benching results have revealed a large coherent gold-copper-molybdenum anomaly over an altered diorite intrusion with evidence of porphyry style mineralisation.

?Further interpretative and field work is also underway over other prospects with the aim of firming up a pipeline of other targets for drill testing,? the company said.
