15. Newly Identified IP
Chargeability Anomalies
Anomalies May Indicate Additional Areas of Porphyry Copper Mineralization
 IP anomaly extends
for 2km north west of
deposit – untested by
drilling
 Two additional IP
anomalies located in
NW Expo area – one
area un tested by
drilling
TSXV: NCX 15

16. Additional Targets
- NW Expo Area
- Mo and Au mineralization demonstrated in drill holes over 600 metres strike
- Two new IP chargeability anomalies may indicate new areas of porphyry
copper mineralization.
- Hep Showing
- Copper soil anomaly not fully evaluated
- South MacIntosh
- Broad area of alteration partially drill tested
- Pemberton Hills
- High level alteration may indicate porphyry deposit at depth
- Rupert
- Magnetic anomaly and two untested IP chargeability anomalies.
