2 INTRODUCTION This report deals with the results of MaxMin II electromagnetic surveys on the Airport C*G grid in Jessop township conducted by Exsics Exploration Limited for Norcen Energy Resources Limited. Survey coverage was completed on the claims as listed below in Jessop township (see grid steten Figure 3). P P P P P P P The grid plans showing low frequency and high frequency electromagnetic results and the contoured magnetometer results are presented with this report as Maps l, 2 and 3 in the back pocket.

4 LOCATION AND ACCESS The Airport C*G grid is located approximately 5 kilometres northwest of the Timmins Airport in Concessions 4 and 5, Lots 11 and 12 of Jessop township. Helicopter access to the property was provided by Huisson Aviation Ltd. of Timmins (see Figures l and 2).

8 GEOPHYSICAL SURVEYS 1. Electromagnetic Survey The electromagnetic survey was completed with a MaxMin II electromagnetic instrument manufactured by Apex Parametrics Ltd. utilizing a 150 metre reference cable. Operating frequencies of 444 and 1777 Hz were recorded throughout the survey. Technical and operational specifications of the MaxMin II instrument are included as Appendix A of this report. The results of the EM survey are presented as Map l (showing the 444 Hz frequency) and Map 2 (showing the 1777 Hz frequency) in the back pocket of this report. These results are summarized below.

9 2. Magnetometer Survey A Geometrics G-816 proton precession magnetometer was used throughout the survey. Correction for diurnal variations in f the magnetic field were made by reference to the Recording Base Station Magnetometer G-826A manufactured by Exploranium Geometrics Ltd. 3. Survey Results The MaxMin survey noted 4 conductive zones across the grid called A, B, C and D. Zones A and B extend off the grid to the east but closed to the west. Zone C is also open to the east and closed to the west. Zone D is open to the west and probably closed to the east. All zones appear to parallel the baseline at Conductor Characteristics Zone A L375 me to L625 me 420 mn: MaxMin 1777 Hz - Strike of Depth to Soural of 12 metres

10 4. Conductor Characteristics (Cont'd) Zone A L375 me to L625 me 420 mn: MaxMin 1777 Hz 444 Hz Magnetics Zone B L750 E to 1000 me MaxMin 1777 Hz 444 Hz Magnetics - Conductivity value of 14 mhos - Dip is near vertical - Strike and dip is similar to the 1777 Hz - Depth to source of 25 metres - Conductivity value of 26 mhos - There is a good correleation with the majority of the zone - The conductor has a strike of 095" for 250 m plus open to the east - Depth to source of metres - Conductivity value of 3 mhos - Dip is near vertical - Strike and dip is similar to 1777 Hz - Depth to source is metres - Conductivity value of 6-8 mhos - Mag shows good correlation in the east portion of the zone striking off the grid to the east

11 4. Conductor Characteristics (Cont'd) Zone C L750 me to 1375 me slightly north of the base line 1777 Hz - Strike length of 625 m open to the east at Az 090" - Depth to source of metres - Conductivity of the zone 2.5 mhos 444 Hz - Strike and dip is similar to 1777 Hz - Depth to source of metres - Conductivity value of 3-10 mhos Magnetics - There is good mag correlation with the zone consistantly up to U125 me - The contour plot also shows a vertical dip

12 4. Conductor Characteristics Zone D L500 me to LOfOO 450 ms 1777 Hz 444 Hz Magnetics - Strikes for 375 m plus, open to the Depth to source of metres - Conductivity of 5-10 mhos getting stronger to the west - Dip is near vertical - Dip and strike is similar to 1777 Hz - Depth to source is metres - Conductivity value of 5-7 mhos - There is good mag correlation with the entire conductor axis also extending off the grid to the west

13 CONCLUSION Zone A and B are defining the same conductive horizon which has been slightly faulted. This is evident in the mag contour which shows a dike like intrusion following L750 rae and to a lesser extent along L875 me. All zones surveyed by MaxMin have adequate coverage for profile interpretation. No further geophysics is required for drill hole set-ups.
