Additional Phase Two Drilling Results From Lemonga Gold Prospect
Southern Arc Minerals Inc. (TSX Venture: SA) is pleased to announce that the company has received assay results from a further five diamond drill holes of its phase two drilling program at the Lemonga Prospect located on Sumbawa Island, Indonesia. Holes LDG-35 to LDG-39 were drilled to test lateral extensions of high-grade gold-silver shoots intersected in an earlier scout drilling program, along with CSAMT ("resistivity") linear targets interpreted as extensions of known veins and breccia zones.
News release 06-04 (January 31, 2006), 06-05 (February 21, 2006), 06-08 (April 4, 2006), and 06-11 (April 20, 2006) reported on the first eighteen drill holes of the phase two drill program. Subsequent drill holes LDG-35, LDG-37, and LDG-38 continued to test extensions and continuity of gold-silver intercepts from the southern extremes of the Amy Vein.
Drill holes LDG-36 and LDG-39 targeted regions of resistivity highs in the east of the prospect area, interpreted as underlying both the western and central Baleong hydrothermal breccia zone. Both holes were drilled more or less along the same section, but on either side of scout drill hole LDG-13 (2.90 m @ 2.10 g/t Au & 125 g/t Ag). All holes were drilled at right angles to the strike of the veins and/or interpreted resistivity zones at -45º inclinations.
Highlights of drill hole intercepts (Figure 1) returned:
|Drill hole LDG-35||1.70 m @ 10.01 g/t Au & 32 g/t Ag from 127.55 m|
|Drill hole LDG-36||0.60 m @ 2.02 g/t Au & 49 g/t Ag from 28.80 m
1.05 m @ 11.87 g/t Au & 185 g/t Ag from 52.00 m
0.75 m @ 8.91 g/t Au & 33 g/t Ag from 117.40 m
0.40 m @ 3.98 g/t Au & 3 g/t Ag from 184.25 m
0.55 m @ 2.50 g/t Au & 3 g/t Ag from 217.95 m
|Drill hole LDG-37||0.90 m @ 1.34 g/t Au & 39 g/t Ag from 36.50 m|
|Drill hole LDG-38||4.20 m @ 6.20 g/t Au & 12 g/t Ag from 63.20 m
1.25 m @ 1.59 g/t Au & 39 g/t Ag from 82.95 m
|Drill hole LDG-39||4.0 m @ 0.64 g/t Au & 262 g/t Ag from 81.90 m
(including 2.0 m @ 1.06 g/t Au & 379 g/t Ag)
Further results from the southern segment of the Amy Vein, particularly from drill holes LDG-35 and LDG-38, confirm the presence of higher grade ore shoot(s) exhibiting an irregular surface confined by the geometry of a second generation auriferous quartz-sulfide vein event. Previous petrological interpretation has suggested the possibility of considerable depth potential for extensions of such shoot(s) over an approximate length of 225 m of the poorly outcropping southern Amy Vein segment. These deeper targets will be tested in forthcoming drill holes.
The extensive Baleong hydrothermal breccia zone exhibited better precious metal grades on its western rim than within the central portion. This might be attributed to late-stage auriferous quartz±sulfide veins and veinlets, preferentially occupying the more silica altered extremes of the breccia. Further surface work, such as trenching within both western and eastern edges of the breccia body, will be undertaken prior to any further drilling in this area.
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.
