Augur Resources: Randu Kuning high grade zone extended

ASX-listed Augur Resources Ltd announced Wednesday that assay results from the first two holes completed as part of the current drill program at its Wonogiri gold-copper project in Central Java, Indonesia, have successfully extended a high grade gold zone intersected by previous Augur drilling in 2012.
The company said in a statement that drill holes WDD051 and WDD052 were designed to test for extensions of higher grade gold (>1.0 g/t Au) zones previously intersected within the Randu Kuning resource area by holes WDD009 (25.0 meters of 1.03g/t Au and 0.23% Cu) and WDD050 (104.1meters of 1.08 g/t Au and 0.25% Cu) respectively. Both WDD009 and WDD050 ended in mineralization.
WDD052 was drilled down and began coring from the bottom of the previous hole WDD050 (210.1 meters) to a hole depth of 384.1 meters. Assay results from WDD052 returned a 60.9 meter intersection grading 0.57 g/t Au and 0.16 % Cu from 210.1 to 271.0 meters. Included in this is an 18.9 meter interval of 1.01 g/t Au and 0.16% Cu from 210.1 to 228.0 meters downhole.
These intersections effectively extend the mineralized zone intersected in WDD050 to a combined (WDD050,WDD052) 165.0 meter wide mineralized zone of 0.81g/t Au and 0.16% Cu from 106.0 to 271.0 meters. Contained within this is an interval of 128.0 meters of 1.02 g/t Au and 0.21% Cu from 106.0 to 234.0 meters. The entire combined 384.1 meter length of the two drill holes averages 0.45 g/t Au and 0.13% Cu.
The 60.9 meter intersection in WDD052 lies within the conceptual open pit model prepared as part of the scoping study.
WDD051 drilled down through the previous hole WDD009 and began coring from the bottom of the previous hole (305.6 metres), continuing to a hole depth of 388.2 metres. WDD051 intersected a deeper zone of 4.3 metres of 0.99 g/t Au and 0.06% Cu from 368.7 metres downhole, including a 1.0 metre intersection of 2.78 g/t Au and 0.2% Cu.
This may represent the vertical continuity of the deep high-grade intersection from previous PT Oxindo Exploration drilling (DDH002) which intersected 45.0 metres of 1.49 g/t Au and 0.21% Cu from 450.0 metres downhole, including a 13.0 metre interval of 2.34 g/t Au and 0.31% Cu from 482.0 metres downhole.
Higher grade zones (≥ 1.0 g/t Au) are interpreted as structurally-controlled ?feeders? related to zones of hydrothermal breccia and sheared rock which based on surface mapping are interpreted to have a general sub-vertical orientation.
