INTRODUCTION AND SUMMARY

The WILDROSE mineral claims are located some 10 kilometers south of the city of Kamloops via highway 5, as indicated on the accompanying location plan plate 128-78-1. The lines surveyed are indicated on accompanying claim map, plate 128-78-2.

During the period April 18-22, 1978 a Cominco geophysical crew completed some 7.7 line kilometers of induced polariza- tion surveying over a portion of the WILDROSE claims. On May 5, a magnetometer survey was conducted over the same grid lines.

This report describes these geophysical surveys and discusses the results obtained.

GEOPHYSICAL SURVEYS

Magnetics Survey

The magnetics survey was conducted by Boris Lumm, geophysicist in training. A Scintrex MP-2 total field proton precession magnetometer was deployed on the survey. The unit has a scale sensitivity of 1 gamma. Readings were normally taken at 30 meter intervals, with fill in readings in areas of steep magnetic gradients. The data is presented in contour plan form as accompanying plate 128-78-3.

Induced Polarization

G.J. Niaeyer, geophysical technician, was the party chief/ receiver operator on the IP survey.

A Scintrex IPR-8 receiver in combination with a Huntec 7.5 KW motor generator/transmitter were utilized. operates in the time domain with a 2 sec on and 2 sec off pulse. The data plotted is the M value and the units are millivolts per volt. millisecond value (such as the IPR-7) the numbers would be multiplied by 0.7 (for a "typical" decay curve). The reader is referred to the Scintrex manual for a more detailed discussion of this instrument.

The pole-dipole electrode array was used on the survey, with an "a" spacing of 90 meters and "n" separations of 1 and 2 only. Readings were taken at 90 meter intervals.

The chargeability and apparent resistivity data are pres- ented in standard pseudo section form as plates 128-78-4 to 128-78-7.

DESCRIPTION OF RESULTS

A zone of moderately high chargeability was detected on the east portion of survey lines OON and 300N. The zone is coincident with low apparent resistivity values and high magnetic field values.

The anomaly has a peak value of 32 millivolts per volt (n=l) at station 1035E on line OON.

The rest of the survey area is characterized by low charg eabili ty values .

CONCLUSIONS

Portions of the WILDROSE mineral claims were surveyed with pole dipole time domain IP, and total field magnetics, in the spring of 1978.

A moderately anomalous chargeability high was detected on the east portion of lines OON and 300N. A geological and geochemical evaluation of this anomaly may indicate if drill testing is warranted.
