Phase Two Drilling of Lemonga Epithermal Gold Prospect Commences
Southern Arc Minerals Inc. (TSX Venture: SA) is pleased to announce the commencement of phase two drilling at its Lemonga Prospect located on Sumbawa Island, Indonesia. This program will consist of 3,500 metres of diamond drilling designed to test continuity of high-grade gold-silver shoots in quartz veins intersected in an earlier scout drilling program (16 holes totaling 1,498.75 m). One drill rig is currently in operation and will be followed by a second rig which will be used for shallower infill drill holes and peripheral exploratory scout holes.
The Lemonga Prospect is focused on a low-sulphidation epithermal quartz vein system over which surface mapping by Southern Arc and previous operators has confirmed hydrothermal argillic alteration within an area approximately 1 km East-West by 1.5 km North-South. Five quartz vein targets, named Amy, Betty, Cici, Dessy and Evi, have been identified within the alteration zone. The best exposed vein, the Amy Vein, has a mapped strike extent of at least 950 meters. Eight drill holes have been drilled along the strike of the Amy Vein, with high grade shoots intersected in the southern portion over a 300+ m strike extent.
Previously reported Amy Vein intercepts (Figure 1) include:
Drill hole LDG-01 | 16.05 m @ 5.3 g/t Au & 51 g/t Ag from 56.15 m (including 3.00 m @ 19.1 g/t Au & 228 g/t Ag from 69.20 m) |
Drill hole LDG-03 | 15.40 m @ 6.67 g/t Au & 36 g/t Ag from 20.70 m (including 2.00 m @ 25.67 g/t Au & 25 g/t Ag from 20.70 m and 5.40 m @ 8.27 g/t Au & 79 g/t Ag from 30.70 m) |
Drill hole LDG-16 | 0.85 m @ 9.85 g/t Au & 12 g/t Ag from 121.20 m 13.00 m @ 1.83 g/t Au & 4 g/t Ag from 80.90 m (including 5.00 m @ 3.37 g/t Au & 5 g/t Ag from 85.90 m) and 5.00 m @ 1.16 g/t Au & 5 g/t Ag from 104.90 m |
Drill hole LDG-11 targeting the Desy Vein intersected elevated gold-silver values including: | |
7.90 m @ 5.81 g/t Au & 37 g/t Ag from 41.80 m (including 3.20 m @ 12.71 g/t Au & 64 g/t Ag from 46.50 m) |
The remaining widely spaced drill holes intersected quartz veins carrying anomalous levels of gold and silver.
Ground geophysical surveys using CSAMT resistivity mapping techniques have been completed over the entire prospect area at 20-m centres, along 50-m spaced grid lines. Results show high resistivity zones with significant lateral persistence tending to more or less coincide with known or inferred out-cropping quartz veins and silica-rich brecciated bodies. Very low resistive background appears typical of argillically altered and/or strongly fractured wall rock. Results have been incorporated into the forthcoming drilling program.
Results of routine petrological studies on drill core samples by Sinclair Knight Merz (SKM), New Zealand suggests that at least 450 m vertical extent of potential gold-silver mineralization remains intact largely above the boiling zones of an extensive paleo-hydrothermal upflow regime. SKM recommends "...that further drilling should be targeted at relative levels below 50 metres above sea level at vein swells and if this is successful breccia pipes should be targeted at a similar depth particularly where they are intersected by veins...." Again such concepts have included into positioning of drill holes.
