INTRODUCTION

During June 1983, a geophysical crew, under the direction of the author, carried out magnetometric and electromagnetic surveys over grid Gapp ?-82, Montreal River Project, Gapp Township, Ontario, on behalf of Noranda Exploration Ltd.

The grid is located north-west of Gapp Township, Ontario, some 75 kilo meter north-east of Sault Ste-Marie. The property is accessible by Lum ber Road north of Searchmont.

The claims covered by this survey are registered with the Ministry of Natural Resources of Ontario under the following claim numbers: -

CLAIMS LICENCES NUMBERSt

687677-, 687678, 687679, 687680

The purpose of this survey was to outline and investigate Input anomalies. These anomalies were first outlined from an airborne survey carried out previously.

The grid consisted of a total of 7.2 km of lines and base line, oriented N130 0 at 100 m centers. A total of 6.3 line km of electromagnetic and magnetometric surveying were carried out over this grid.

The instrument used for the electromagnetic survey was an Apex Maxmin II, horizontal loop, electromagnetic unit operating at frequencies of 444 Hz and 1777 Hz with a coil separation of 10C meters. The magnetometric sur vey was carried out using a Geometrics, Model G-816, Portable Proton Mag netometer, which measures the earth's total field with a sensitivity of 1.0 gamma. Base stations for diurnal corrections were established along

the base line....12

Concentrations of minerals having magnetic susceptibility will give rise to variations in the earth's magnetic field. The data obtained by sys tematic observation of the intensity of the earth's magnetic field has been contoured and the results show magnetic patterns or anomalies. Mi nerals having strong magnetic susceptibility are generally magnetite or pyrrhotite, and are usually, but not necessarily, associated as primary or accessory minerals in massive sulphide deposits; thus, coincident mag netic and electromagnetic anomalies could be important.

Electromagnetic methods are capable of delineating zones of conductivity that could represent massive concentration of minerals having metallic conductive properties. Such minerals are pyrite, pyrrhotite, chalcopy rite (but not sphalerite) and graphite. It is rarely possible, from E.M. data alone, to differentiate between these various sources of conducti

vity.

DISCUSSION OF RESULTS

Magnetic survey:

One (1) drawing shows the magnetometric data on a horizontal scale of 1:2500. The magnetometric data has been contoured and shows magnetic patterns or anomalies.

The compiled magnetic data shows a magnetic formation north of the base line with isolated height up to 4922 gamma. South of the base line, we observed few isolated height which might represent lenses of high magne tic minerals alligned and oriented roughly N1300 , parallel to the base

line.

Electromagnetic survey:

Two (2) drawings show the electromagnetic data on a horizontal scale of

on a scale of 1 cm s 105K.

tained. The trend observed is N1300 . The following parameters havebeen established on line 7E, with

CONCLUSION

The present survey has adequately outlined four (4) conductive zones. Those zones were interpreted separately and different parameters were 'jstablished. Recommendations concerning diamond drilling follow up were made in each case, sulphides and/or graphite are suggested to be

the likely source of conductivity.
