Augur reports drilling results from C. Java gold project

Hole WDD017 was drilled to test for further mineralisation to the north of the mineralisation at Randu Kuning. This hole is located approximately 50 metres north of WDD015 (182.0 metres at 0.75 g/t gold and 0.17% copper), which had previously been the northern most hole. WDD017 intersected a zone of 55.0 metres at 0.41 g/t gold and 0.16% copper. This is significant as it indicates that mineralisation continues to the north of the previously identified mineralised zone and supports the potential for mineralisation at depth.
Hole WDD018 intersected two significant zones of mineralisation. The shallower zone returned 136.0 metres at 0.48 g/t gold and 0.14% copper from 73 metres. This zone included 4.0 metres at 2.35 g/t gold and 0.3 7% copper. A second deeper zone of 106.5 metres at 0.64 g/t gold and 0.10% copper from 278 metres was intersected. This lower zone ended in mineralisation.
Hole WDD018 was drilled from the same drill pad as WDD016, with the angle of the drill hole 15 degrees steeper than that used for WDD016. The results continue to indicate that there is apparently continuation of the mineralisation between holes and at depth.
Mineralisation is associated with quartz stock working and as disseminated mineralisation within a mirco-diorite. The two zones in hole WDD018 are separated by an intense zone of quartz and magnetite veining. Interpretation of recent drilling data and ground magnetic data highlights the potential for further mineralisation to the west and at depth of the current drilling. The mineralised zone to the north remains open and consideration is being given to drill some deeper holes to the south of the known mineralised zone as there is potential for mineralisation below the zone tested by Augur.
Data from local geology and recent drilling indicates that the mineralisation at Randu Kuning is related to a near vertical gold-copper porphyry within a large eroded volcanic centre, possibly related to a northward migrating Oligocene to Miocene volcanic arc. A number of significant porphyry deposits (+/- associated epithermal mineralisation) sit along this zone including Newmont Mining Corporation?s operation at Batu Hijau (914Mt at 0.53% Cu and 0.40 g/t gold), Newmont?s Elang deposit on the island of Sumbawa and Intrepid Mines Tujuh Bukit (990Mt at 0.40% copper and 0.45 g/t gold) in eastern Java.
