Latest Phase Two Drilling Results From The Lemonga Gold Prospect
Southern Arc Minerals Inc. (TSX Venture: SA) is pleased to announce the satisfactory completion of its phase two drilling program, with a total of 5,655.50 metres drilled in 40 diamond core holes, at the Lemonga Prospect located on Sumbawa Island, Indonesia. The final holes LDG-45 to LDG-56 were drilled mainly to test lateral extensions of high-grade gold-silver shoots intersected in previous drill holes of both this and an earlier scout drilling program. Final assay results for ten drill holes, LDG-45 to LDG-54, have been received.
News releases 06-04 (January 31, 2006), 06-05 (February 21, 2006), 06-08 (April 4, 2006), 06-11 (April 20, 2006), 06-12 (May 9, 2006), and 06-13 (May 24, 2006) reported on the first twenty-eight drill holes (LDG-17 to LDG-44) of the phase two drill program.
A variety of targets were tested in these final holes. Drill hole LDG-45 targeted a relatively shallow CSAMT anomaly adjacent to silicified hydrothermal breccia sub-crop north of the Amy Vein, while drill holes LDG-46 and LDG-47 continued testing the northerly extensions of the Betty and Cici sheeted vein complex, recognized in previous drill holes. Extensions of both the Dessy and Evi Veins were explored in drill holes LDG-48, LDG-49, LDG-51, LDG-52, and LDG-54, while drill holes LDG-50 and LDG-53 targeted depth extensions of the south and central Amy Vein segments, respectively.
All holes were drilled at right angles to the strike of the veins at -45º and -60º inclinations and, except for LDG-48, intersected significant widths and grades of gold-silver bearing quartz vein zones.

Drill holes LDG-46 and LDG-47 both confirm the northern strike extension and depth continuity of grade of the Betty/Cici sheeted vein complex. Whilst only a nominal five drill holes have been completed in the area to date, a possible low-grade bulk tonnage scenario exists based on vein zones intersected of 45m to 110m width and along strike (northwards of LDG-46 and southwards to LDG-15) and down-dip continuation of mineralization.
Drill hole LDG-48 appears to close off the Dessy Vein to the north, although further trenching is warranted to confirm this. Drill holes LDG-49 and LDG-54 effectively double the known strike length of this vein, which still remains open to the south and at depth. Similarly drill holes LDG-51 and LDG-52 into the Evi Vein confirm the lateral extent of previous gold-silver intercepts from drill hole LDG-34 (9.95m @ 3.82 g/t Au & 29 g/t Ag). This vein also remains open at depth and long strike, with further trenching required north of drill hole LDG-12.
Drill hole LDG-50 was drilled beneath the previous wide quartz vein intercept in hole LDG-16, but proved inconclusive in extending the vein to depth. However, a significant width of gold-silver mineralization (1.65 m @ 28.90 g/t Au & 124 g/t Ag) hosted in coarsely crystalline massive sulfides was intersected in the upper portions of the hole, indicating the structural and mineralogical complexity of the Amy/Betty Vein convergence area. Although drill hole LDG-53 intersected an 8.3m wide zone of quartz and peripheral stockworks at the projected target depth, gold and silver grades fell below those expected. Similar to the previous drill hole LDG-02, immediately up dip, the vein zone is partly oxidized and extremely broken, with strong artesian water flows encountered, implying a major structural feature, with possible flushing of gold and silver particles from the zone.
All data is currently being finalized into a format whereby the resource potential may be indicated.
The Lemonga Prospect is a low-sulfidation epithermal quartz vein system over which surface mapping by Southern Arc has confirmed argillic alteration dominant within an hydrothermal upflow area approximately 1 km East-West by 1.5 km North-South. Five auriferous 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.
