INTRODUCTION

In April, 1991, a magnetic survey and electromagnetic H.E.M. survey were carried out on a property owned by COMINCO LIMITED, BURRO Project, in BurroJ5Township, province of Ontario.

These surveys were designed to locate structures favorable for base metal deposition.

PROPERTY. LOCATION AND ACCESS

The property is located approximately 80 km South of the town of Timmins, in Burrows Township, province of Ontario.

The property is accessible by secondary roads which can be taken from the highway 1560 or #144.

The property claims have been registered with the Ontario Department of Natural Resources and the numbers are presented on figure #1.

GEOPHYSICAL WORK

A total magnetic field survey and electromagnetic H.E.M. survey were carried out on part of the property between April 10th and 15th, 1991.

A total of 29.2 km was covered by the magnetic survey using the EDA OMNI-PLUS proton precession instuments. The H.E.M. survey was conducted over a total of 25.5 km using an APEX PARAMETRICS MAXMIN I instrument, operating at three frequencies.

-2-

SURVEY SPECIFICATIONS

The geophysical surveys were carried out along a network of North - South picket line cut at 100 metres intervals. The lines were chained and stations marked at 25 metres intervals.

The magnetic readings were taken with a proton precession magnetometer recording simultaneously the value of the total magnetic field and the measurement of the vertical gradient, with a precision of 0.1 gamma and 0.1 gamma/metre respectively. The separation between the sensors was 0.5 metre and the height of the upper sensor was 3.2 metres above the ground. The readings were taken systematically every 12.5 metres.

A base station magnetometer measuring the variation of the total magnetic field at 20 seconds intervals was used as a reference for correction of the diurnal variation.

The electromagnetic survey was carried out using a MAXMIN I, which was used in the horizontal loop mode with a 150 metres separations between the transmitting and receiving coils. Reading were taken at 25 metres intervals along the lines.

The instrument is capable of operating on nine different frequencies of which 440, 1760 and 3520 Hz were selected. In this type of survey, both in phase and out of phase components of the secondary field are measured and are recorded as percentages of the primary field.

RESULTS AND INTERPRETATION

The magnetic relief shows a predominance of NW-SE striking units among a background level of 58450 i 50 gammas. Probably originating from late, cross-cutting mafic dykes, these features define an important network of structural lineaments which cut and possibly displace the otherwise East- West to NE-SW stratigraphy.

The range of amplitudes of the anomalies extends from 100 gammas to 1000 gammas above backgound and the wavelengths are generally diagnostic of units lying at dephs of 25 to 80 meters.

Only in the Southwest are there magnetic units which strike along East-West directions and probably represent the signatures of mafic volcanic flows.

The MaxMin H.E.M. survey has mapped two types of conductors. First there are conductors of definitely massive metallic nature, in the areas of/450E/425N. These conductors are caused by either sulphidic or graphitic horizons in the bedrock. The interpreted depths of these conductors are in the range 30m - 35m. The conductor in the West strikes NE-SW where as the conductor in the East strikes East-West.

The second type of conductor is of electrolytic nature or poorly-connected metallic stringers or veins. They seem to occur in areas of intense bedrock relief and as such could well be related to tectonic phenomena such as faults and shear zones. Indeed, we have traced two possible faults in the area around 850E/550N.

Also evident in the MaxMin profiles are bedrock ridges which can be identified by positive quadrature peaks associated with the resulting higher apparent resistivities.

-4-

CONCLUSION AND RECOMMENDATIONS

The geophysical investigations which were carried out on the BURRO property have successfully mapped a dominant NW-SE tectonic fabric cross-cutting an East-West to NE-SW trending stratigraphy.

Two massive metallic conductors were delineated and a number of less conductive zones. If structure-hosted mineralisation is the target, there is an opportunity in the central sector of the property where disruptions and changes in direction are quite prominent.

If massive sulphides are to be explored, the two "good" conductors should be drill tested to see if they are due to sulphides or graphite.

Of course, the present results, examined in the light of additional geoscientific information should help in providing a better understanding of the lithological and stratigraphic complexities of this area.
