GEOPHYSICAL SURVEYS

1. Electromagnetic Survey

The electromagnetic survey was completed with a MaxMin II

electromagnetic instrument manufactured by Apex Paranetrics

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 44 Hz frequency) and Map 2 {showing the 1777 Hz

frequency) in the back pocket of this report. These results

are summarized below.

2. Magnetometer Survey

A Geometrics G-816 proton precession magnetometer was used

throughout the survey. Correction for diurnal variations in

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 located two anomalous zones (A and B)

4. Conductor Characteristics

Zone AL375 mE to L750 mE

135 itiN to 150 mN

MaxMin1777 Hz - Strike length of 250 metres

@ 0850

- Dip is near vertical

- Depth and conductivity of the zone is questionable due to the presence of conductive overburden

444 Hz - Strike and dip is similar to the 1777 Hz

- Depth to source of less than 50 metres

- Conductivity of 20-35 mhos

4. Conductor Characteristics (Cont'd)

Zone AL375 iHE to L750 mE 135 mN to 150 mlJ

Magnetics - There is no apparent magcorrelation with the conductor* The only nag noted is on the east portion of the grid extending from L500 mE to 750 mE flanking Zone A to the north and an east- west trend south of the baseline on 250 mE to 500 mE

Zone BLO+00 to 250 mE 45 mS to 15 mN

1777 Hz - Strike length of 250 m @ 0750

- Dip direction of near vertical

- Depth to source of approximately 30 metres

- Conductivity of 15 mhos

444 Hz - Strike and dip is similar to 1777 Hz

- Depth to source of less than 50 metres

- Conductivity of 10 to 20 mhos

Magnetics - Mag shows strong north flanking mag on LO+00 which is broadening to the east

CONCLUSIONS

Both zones are well defined anomalies on the 444 frequency but

are underlying a sheet of highly conductive overburdent liiis

conductive overburden is very evident on the 1777 frequency

increasing eastwardly from L125 raE.

Also, zones A and B are probably defining the same conductive

horizon which may have been shifted or faulted slightly.

RECOMMENDATIONS

Ito further geophysics is required to define the zone and if

drilling is required, L125 mE or L500 mE should be considered.
