Further Wonogiri drilling results return broad zones of gold, copper mineralization: Augur

Hole WDD003 was drilled to test the eastern edge of a broad stockworking zone in the southern portion of the Randu Kuning prospect. The hole was collared at the eastern extent of an anomalous surface trench (98 metres at 0.91 g/t gold and 0.29% copper), the company said.
Hole WDD003 intersected, three significant zones of gold mineralisation within the top 20 metres including 5.2 metres of 0.85 g/t gold from surface and 4.5 metres at 0.97 g/t gold and 0.26% copper from just 9.5 metres. These results show that gold mineralisation extends further east than identified in the recent trenching at Randu Kuning, it said.
Hole WDD004 was drilled approximately 50 metres north of hole WDD003 and approximately 55 metres south of hole WDD001 (53.6 metres at 1.4 g/t gold and 0.3% copper). This hole intersected weakly anomalous gold in the first 6.0 metres before intersecting a zone of 37 metres at 1.23 g/t gold and 0.44% copper.
Gold and copper in this zone is associated with a broad zone of quartz stockworking and sheet quartz veins in a mircodiorite. Copper bearing chalcopyrite has also been identified as disseminations within the mircodiorite host rock. Alteration in the mineralised zone is interpreted as potassic and the style of mineralisation is interpreted to be of a gold-copper porphyry system. Arsenic levels are generally below detection over the mineralised zone and this is regarded as highly favourable.
The promising results encountered at Randu Kuning has led to Augur seek a second drill rig for further testing at Randu Kuning and at a number of other prospects within the northern Wonogiri project area.
Managing Director Grant Kensington commented: ?The new results continue to be very encouraging. The historic drill results, the recent trenching results and our new drill results continue to indicate a significant zone of gold mineralisation. As a consequence, our drill program has been extended to test continuity of minerailsation at depth and to advance this testing a further drill rig has been sought.
The area has potential for a large bulk-tonnage gold deposit.?
Augur is awaiting results for the remainder of hole WDD001 below 70.9 metres, WDD002 and WDD005. Augur is currently using two laboratories in Indonesia to try and improve turnaround time on sample analysis.
Trenching continues within the Northern Wonogiri area. Reassessment of historic geophysical data and current trench geology data has led to the trenching program being extended to a number of new areas.
As drill targets are finalised, Augur plans to commence drill testing of these targets.
Diamond drilling on a 50 by 50 metre grid is occurring at the Randu Kuning prospect to test the surface mineralisation exposed in the trenching program and to test previous drill intersections of PT Oxindo.
An ongoing trenching program within the Wonogiri project will continue to test areas of mineralised vein systems identified by Augur and PT Oxindo. Results from this trenching will be used to further develop drill programs to test these additional prospects. (romel)
