Sydney, Feb 6, 2008 AEST (ABN Newswire) - Results from Robust Resources Limited (ASX: ROL) ("Robust") initial drilling programme at its Bauloora Mine prospect - near Cootamundra in the NSW Lachlan Fold Belt, has shown the main vein to extends to the North and South. It remains open in these directions and also down dip. A further intersection approximately 150m to the East indicates that a multiple vein system may exist.
The vein system occurs within a 27 sq km epithermal alteration halo, which indicates that a more substantial resource may lie at depth. The drilling program consisted of 2 pre-collared diamond holes and 10 RC percussion holes.
Drilling Program
A 12-hole drilling program was undertaken from late October to mid November 2007. In all 2 precollared diamond holes and 10 RC percussion holes were completed. Five of the holes, including the 2 diamond holes, were designed to test the main Bauloora vein at depth and along strike. The balance were designed to test various bedrock anomalies in the general vicinity of the main vein.
Eleven of the holes were drilled at 50 degrees declination to the east, and one (hole 5) at 50 degrees to the west. The two diamond holes, designated holes 1 and 2, were pre-collared (RC percussion) to 60 and 100 metres respectively, and reached final depths of 162 and 262 metres.
The 8 RC percussion holes ranged from 50 to 120 metres depth. In all 264 metres of diamond and 868 metres of RC percussion drilling was undertaken. In the 2 diamond holes mineralisation was noted to occur in 4 to 6 narrow, steeply dipping brecciated (silica-carbonate-chlorite-kaolinsulphide) veins cross-cutting (shallow dipping) acid volcanic rocks (mainly medium grained rhyodacitic tuffs, with minor fine grained water lain equivalents).
Host rocks were silicified, chloritised and epidotised to varying degrees, especially adjacent to veins. Sulphides occurred in most veins, varying in concentration from minor to abundant. They consisted of mainly fine-grained (honey coloured) sphalerite and fine to very fine-grained "sooty" galena, with lesser chalcopyrite, pyrite and arsenopyrite.
In the 10 RC percussion holes, veins, sulphides and weathered (ferruginised) sulphides were locally evident, but were not as distinct as in the 2 diamond holes. Visual evidence pointed to the presence of 6 narrow sulphide bearing "veins" each of holes 1 and 2, four of which contained Pb and Zn sulphides.
2008 Exploration Programme
As a result of the positive drilling from Bauloora the Company anticipates that further, deeper, drilling will be undertaken later in the year.
