| ABSTRACT: | Arc Exploration Limited (ASX Code: ARX) announces this update on exploration work on the Trenggalek Project located in East Java, Indonesia (Figure 1). A new phase of diamond drilling commenced at Trenggalek in early February 2016. This program was designed to test for mineralised extensions within the large Sentul and Buluroto epithermal gold veins, which were previously identified with scout diamond drilling by ARX in 2010/11. Gold results for the first sixteen holes in this latest drilling program were reported in earlier announcements (See ASX announcement of 18 th April 2016 and 16th June 2016). The results for the last three holes STDH10 to STDH12 at Sentul are summarised below (See Table 1 and Figures 2 & 3 for drill-hole locations). Drilling in these two prospects has now ceased while further review and interpretation of the results in conjunction which historic data is undertaken. Scout diamond drilling on the Singgahan Prospect located in the southeast corner of the Trenggalek Exploration IUP tenement (Figure 1) was conducted in 2014 (see ARX announcement of 12th May 2014 and 21st July 2014). The four inclined diamond holes (1,541m) drilled at Singgahan completed a fence of holes across part of an extensive copper-gold-molybdenum soil anomaly and coincident magnetic-high anomaly. The source of the soil geochemical anomaly is interpreted to be a weakly mineralised intrusion breccia cropping out at surface. The source of the magnetic high is a small mineralised diorite intrusion that appears to be rootless as modelled by a 3D magnetics inversion analysis. The high-magnetic signature of the diorite is attributed to abundant secondary magnetite occurring as disseminations in porphyry-style quartz-anhydrite veins and potassic-propylitic alteration. Porphyry-style mineralisation was intersected in these holes which returned multiple low grade copper-goldmolybdenum intercepts. | |
