Release: Oropa Ltd: Further encouraging gold hits - Sihayo 1 North resource extensions
Tuesday, January 15 2008 - 01:11 AM WIB
The drilling to the west of the current Inferred Resource at Sihayo 1 North is targeting outcropping jasperoid to potentially increase the resource base in this direction. Currently, the Sihayo 1 North and Sambung deposits at Pungkut collectively contain Inferred Resources of approxmately 710,000 ounces.
The latest results include:
SHDD100: 7m @ 1.33 g/t Au from surface
SHDD101: 3m @ 2.59 g/t Au from 7m
SHDD103: 22m @ 3.96 g/t Au from surface
Hole SHDD101 tested the continuity along the section between the current resource extension drill program and the previous Sihayo 1 North drilling. The significant mineralisation intersected in this hole (3m @ 2.59g/t Au) joins together with the mineralisation intersected in hole SHDD096, as announced on 28 November 2007, (17.55m @ 1.82g/t Au from surface), and previous drill hole SHDD061 (2m @ 4.20ppm Au from surface, 2m @ 6.65ppm from 5m, 19m @ 5.84ppm from 28m).
Drilling approximately 250 metres grid south of SHDD101 in hole SHDD103 assays returned an exciting gold intersection of 22m @ 3.96g/t Au from surface. This result demonstrates continuity with the nearest drill hole, SHDD081, located some 56 metres to grid north, which returned 26m @ 4.47g/t Au from 18m, and SHDD087, 36 metres to grid east, which returned 9m @ 3.47g/t Au from surface and 9m @ 3.21 g/t Au from 12m.
This area alone has the potential to significantly increase the current Inferred Resource at Sihayo North 1.
Holes SHDD099 and SHDD100 were drilled to determine the extent of the mineralisation to the west of the known resource. While hole SHDD099, which did not return any significant results, appears to close off the mineralisation in a south-westerly direction, hole SHDD100, together with the significant results from previously announced hole SHDD098 (6m @ 2.1 5g/t Au from surface), demonstrates that the mineralisation continues to the north-west
This mineralisation is anticipated to be truncated by topography further again to the west, which is supported by data obtained from test pits previously dug in this area.
Assay results are still pending for holes SHDD104 and SHDD105, the final two holes in the recent drilling program at Sihayo 1 North. The diamond drill rig has recently been mobilised to the Sunday Vein at the Hutabargot Julu prospect where it joins the first diamond drilling rig currently operating on the Sarahan Vein.
This preliminary drilling program at Hutabargot Julu is intended to define the geometry and orientation of the veins before drilling targets bonanza mineralisation in this very large epithermal vein system.
All new drill hole collar locations at Sihayo 1 North are currently being accurately surveyed. The database is undergoing validation in preparation for the revised resource estimate, which is scheduled to commence in mid-February 2008. Once the updated resource estimate is completed, the Company intends to initiate a Scoping Study to establish the viability of bringing the Sihayo 1 North and Sambung resources to a mining stage.
The Pungkut Gold Project is located 70km south of Oxiana Ltd?s 6 million ounce Martabe gold deposit(s) in North Sumatra and represents a significant strategic exploration and development opportunity for Oropa, particularly in the current strong gold market environment. (end of edited release)
