As advised on 27 July 2011, hole WDD010 was drilled approximately 63 metres west of hole WDD005 (105.5 metres at 0.95 g/t gold and 0.24% copper from 14 metres depth) within the Randu Kuning prospect. WDD010 tests the down dip extension of hole WDD005.
WDD010 intersected a broad gold mineralised zone from 35 metres depth which includes 113.0 metres at 1.52 g/t gold and 0.23% copper from 50 metres depth and a further 49.0 metres at 1.28 g/t gold and 0.21% copper from 212.0 metres. This zone is associated within extensive stock working and sheeted veins hosted within a micro-diorite.
Drill hole WDD011 has tested the southern strike of mineralisation at Randu Kuning. This hole has intersected a 16 metre gold anomalous zone from 127.5 metres. This zone averages 0.12 g/t gold (0.1 g/t cut-off used). A further anomalous zone exists in the final 3.0 metres of the hole with an average gold grade of 0.15 g/t gold (0.1 g/t gold cut-off used) from 247 metres depth.
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.
Mineralisation within the porphyry at Randu Kuning is contained within extensive stock working and sheeted veins hosted within a micro-diorite and as disseminated copper +/- gold within the mirco-diorite body itself. (romel)
