INTRODUCTION 

This report describes an interpretation of airborne magnetic and VLF 

electromagnetic data collected by Terraquest Ltd. on a block of claims in Rabazo 

Township, Ontario, owned by Bridget Lake Resources Inc., and known as the Bridget 

Lake property. Included in the survey area and attached to this block is claim number 

1218467, owned by a different party. The description of the property and of the 

specifications of the geophysical survey arc given in an earlier report by Charles 

Barrie of Terraquest Ltd. 

The property straddles the Trans-Canada highway some five km south of Wawa 

Ontario. It is underlain by precambrian volcanic rock types, from mafic to 

intermediate in composition, and by ultramafic and felsic intrusive rocks. The 

airborne survey was carried out at a flight line interval of 50 metres with a ground 

clearance of 92 metres. The flight line direction was north south. Ontario Geological 

Survey maps P2682, Rabazo Township, show detailed geology at a scale of l :15,840. 

Two shafts from earlier work arc shown in the northwest corner of the claim group.

OBJECTIVES AND METHODS 

The principal objective of the geophysical interpretation is to gain as much 

information about the geology as possible, especially as related to mineral deposition. 

The VLF cm data will detect electrical conductors that arc caused by conductive 

minerals such as metallic sulphides, but also by moisture filled faults, and nearly 

always by lake bottom sediments. Magnetic data measures small changes in the iron 

content of rock types and so may be used very effectively as a means of updating the 

known mapped geology. 

Various data enhancement methods such as first or second vertical derivative, and 

analytical signal can be helpful in distinguishing near surface features from deeper 

ones. In this project the calculated vertical derivative was found to bc most useful and 

has been presented as figure A, as well as in the Tcrraqucst report. Figure B is the 

VLF data and figure C is the topography derived from the radar altimeter and the 

OPS vertical elevation. 

In order to update the geology the mapped outcrops were digitized and overlain 

onto on the magnetic and VLF maps. The outlines of the geological units were then 

drawn so as to satisfy the mapped geology and the geophysical data. Faults were 

inferred from lateral displacements of linear features and from VLF conductor axes 

that could not be attributed to conductive overburden. 

INTERPRETATION 

VLF Electromagnetic data 

Figure A shows the VLF total field as a colour-shaded grid overlain by topography. 

Most of the large lakes have an anomaly that conforms to the shape of the shoreline and 

these arc believed to bc conductive lake bottom sediments, which is a very common 

condition in the precambrian shield. These have been ruled out as conductors of interest 

with the exception of a NNW trending axis in Blackington Lake which, as will bc shown, 

coincides directly with a fault interpreted from the magnetic data. 

Of the remaining conductors, the most interesting crosses almost the whole of the 

claim block in a WNW direction. Along its western half lies a coincident magnetic 

anomaly, (Fig B). This anomaly is proposed as a fault, mineralized with minor magnetic 

sulphides (pyrrhotite or magnetite) which is conductive by virtue of the sulphides as well 

as a moisture filled cavity. The west half of this fault is recommended as a prospecting 

target and further delineation and investigation is recommended by ground geophysical 

methods, primarily induced polarization. 

Magnetic data 

There arc four main lithologic groups mapped here. The oldest is an intermediate 

to mafic volcanics unit (unit 2) followed in age by felsic volcanics (unit 3), ultrabasic 

intrusive (unit 6) and lastly, felsic intrusives (unit 7). There arc numerous small 

outcroppings of iron formation but these oddly enough do not provide much of a

magnetic anomaly on this survey. Siderite is not very magnetic and any outcrops of 

that mineral will not provide an anomaly. Magnetite is very magnetic and but will not 

provide an anomaly to airborne equipment if the outcrop is very small or has a very 

limited depth extent. 

The interpretation map, figure D, has been drawn mainly from the vertical 

magnetic gradient information, figure B. The intermediate to mafic mctavolcanic unit 

occupies most of the property. Two occurrences of the felsic mctavolcanics (3) and 

felsic intrusive (7) lie to the west. The ultramafic unit 6 is clearly demarcated from 

the others by the magnetic patterns and its contacts have been drawn with 

considerable confidence. There appear to bc a dozen or so separate intrusions of this 

rock type on the property, many of which have been faulted as shown. The other 

geological units arc less well defined and their contacts arc either copied from the 

OGS map or interpolated between outcrops. 

A number of faults have been interpreted from lateral displacements within an 

otherwise linear magnetic unit, and some are supported by a coincident VLF 

anomaly. These arc necessarily speculative in nature but do satisfy both mapped 

geology and the magnetic patterns. In some cases they arc the only explanation for 

the lateral displacements. 

Areas Proposed tor further investigation 

Three areas arc considered of interest and arc proposed for further investigation. 

These arc outlined by a yellow and black polygon on the interpretation map. 

The most important feature appears to bc the long WNW trend ing conductive and 

magnetic linear anomaly in the north part of the property. This feature is magnetic, 

conductive and is supported by the topography shown in the DIM map (figure C). It 

is interpreted as a fault that maybe mineralized by magnetic sulphide minerals such 

as pyrrhotite. It is recommended that further ground geophysical work bc done in this 

zone, and induced polarization would bc the choice to evaluate the sulphide potential. 

Two other zones have been selected based on the interpretation of faults, which 

have displaced basic intrusivcs and may bc an environment for favourable 

mineralisation. The lake bottom sediments undoubtedly contribute to the conductivity 

of the anomaly passing through Blackington Lake, but it was thought worthy of 

interest because of its direct coincidence with the interpreted fault. 

The second of these zones is the coincident conductor and interpreted fault 

trending NW through the southwest comer of claim 1218467. This is a less definite 

VLF anomaly and is not really supported as a fault by the DTM map, but was still 

thought worthy of additional investigation owing to the coincidence of fault and VLF 

conductor.

CONCLUSIONS AND RECOMMENDATIONS 

The airborne magnetic and VLF-EM survey flown at a 50-metre line spacing and 

92 metre terrain clearance has provided excellent data for revising the geological 

map of the area and providing some possible new exploration target areas. New 

contacts and faults have been interpreted and shown on the interpretation map. 

figure D. 

Three areas have been suggested for additional follow up investigation. It is 

recommended that sufficient airborne work has been done and that ground 

geophysical methods such as induced polarization would be the most beneficial 

next step.
