Deep Drilling Target – KSK Copper Project<br />
KSK Copper Project – Beruang Tengah<br />
Beruang Tengah Porphyry Copper-<strong>Gold</strong> Prospect<br />
• The east west magnetic anomaly at Berang Tengah extends for 8000m through<br />
Beruang Kanan and has not been tested.<br />
• Proposal: Drill one deep hole (1,400m) to test porphyry copper‐gold target, represented<br />
by high copper/moly in surface RC, and previous DDH with extensive porphyry‐style<br />
alteration, weak‐moderate stockwork, and increasing Cu/Mo with depth.<br />
SECTION LOOKING NORTH, MAG INVERSION AND MOLYBDENUM IN RC<br />
Au Zone<br />
A zone of intense quartz-sericite (phyllic)<br />
alteration and sheeted sulphide-quartz veinlets<br />
surrounds a central zone of potassic (biotitemagnetite)<br />
alteration.<br />
Classical porphyry-style quartz stockwork veins<br />
crop out at low elevations.<br />
500m northwest of Beruang Tengah, a 1,000m<br />
long zone coincides with a zone of anomalous<br />
gold (>0.1g/t Au) in soils and a 600m wide zone of<br />
highly anomalous copper (>500ppm) in outcrop.<br />
Anomalous gold (>0.1g/t Au) in rock chip<br />
samples closely follows the copper anomaly,<br />
whereas anomalous molybdenum (>50ppm) is<br />
associated with the central potassic and sericitechlorite<br />
alteration assemblages.<br />
