Oxiana <strong>Limited</strong> drilling<br />
Oxiana drilled 10 holes at Beruang Kanan (Fig. 8) where reprocessing <strong>of</strong> the IP data<br />
led them to believe that there was a strong correlation between near-surface<br />
conductive and chargeable zones and copper in drill holes and soils (Stewart et al.,<br />
2007).<br />

Table 3. Significant intercepts in Oxiana drill holes at the Beruang Kanan Prospect<br />
(data from Stewart et al., 2007)..<br />
Five holes were drilled in the Main Zone and most targeted chargeability anomalies<br />
suspected to represent either shallow supergene mineralization or deeper, hypogene<br />
mineralization (e.g. KBK0021). In addition, one hole (KBK0020) tested the<br />
possibility that a buried porphyry could be represented by a low chargeability zone<br />
((Stewart et al., 2007).<br />
In the South Zone, two holes were sited in an area <strong>of</strong> high density quartz-sulphide<br />
stockwork veining with anomalous gold, molybdenum and copper soil geochemistry.<br />
Hole KBK0028 intersected 61m @ 0.21% Cu from surface, including 4.5m @ 7.7g/t<br />
Au from 10m. In the South Polymetallic Zone (Rawa Zone), two holes tested the base<br />
metals zone with limited success. One hole was drilled in the West Zone where an<br />
extensive area <strong>of</strong> anomalous copper in soil geochemistry is present. The drill hole did<br />
not intersect any significant mineralization and the last 100 metres was in postmineral<br />
porphyry.<br />
