1.0 INTRODUCTION

During October 1990 Phelps Dodge Canada acquired through an option agreement with R. Fairservice, a block of 26 contiguous claims located in the Lobstick Bay area, Lake of the Woods, Northwestern Ontario. This claim group covers ground which is thought to be prospective for gold.

The property has been subjected to an exploration program consisting of linecutting, ground magnetic and VLF-EM surveying. Previous magnetic and VLF-EM data have been merged with the recent survey results.

This report pertains to the ground magnetic and VLF-EM surveys and addresses the recommendations for further exploration.

2.0 LOCATION AND ACCESS

This property is located in the Lobstick Bay area, Lake of the Woods, about 7.5 km east of the village of Sioux Narrows at about 49 26'N, 94 55'W on NTS Sheet 52F5 (Fig. 1).

Access to the property is via the Maybrun Road, an all-weather gravel road which passes through the northern portion of the claims and connects to Highway 72 approximately 7 km west of the property at a point 5 km north of Sioux Narrows.

Kenora, located about 55 km NW of the property is the major regional logistical centre and has regularly scheduled aircraft service from Winnipeg and Thunder Bay.

The property is completely forested and is flat to gently rolling; the maximum topographic relief is in the order of 5- 10 m. Parts of the NE portion of the property is covered by cedar swamp and the southernmost part of the claim block covers Lobstick Bay of the Lake of the Woods.

3.0 GEOLOGY

The most recent geological mapping is that of G. Johns, 1984 (O.G.S. Preliminary Map P. 2595-revised).

The property lies in the middle of a 1.5 km thick, east-west trending belt of felsic metavolcanics of the Warclub Group, bordered to the north and south by clastic metasedimentary rocks. Mineral assemblages within the general vicinity of the claim group indicate that the metamorphic grade reached the upper greenschist to lower amphibolite facies. The property lies 3.5 km north of the southeasterly trending Pipestone- Cameron Fault, a major structural lineament which cuts through the general area and hosts gold mineralization elsewhere.

4.0 GEOPHYSICAL SURVEYS

4.1 General ;

The property comprises 26 contiguous claims totalling approximately 1080 acres located on Claim Map G-2627, Lobstick Bay, Kenora Mining Division (Fig. 2) of which 17 claims were covered by the present magnetic and VLF-EM surveys. A list of the surveyed claims is in the Geophysical-Geological- Geochemical Technical Data Statement found in the Appendix. The list is also given in the following Table I. The ground geophysical surveys were carried out by Northwest Geophysics Ltd, of Thunder Bay, Ontario.

The accompanying geophysical maps contain the merged results of previous and the present geophysical surveys. The previous data set was obtained by the Selco Division - BP Resources Canada Limited in 1985 and was submitted for assessment. The new survey covers Lines 700 W to 3100 W inclusive and the previous information is taken from Lines 550 E to 1150 W. From Line 700 W to Line 1150 W only the intermediate lines of the old survey (e.g. L 550 E, L 650 E etc.) were utilised in the preparation of the magnetic!and VLF-EM maps. The new survey also included the coverage; a number of the lines with previous data to facilitate the merging, which was completed by JVX Ltd. of Richmond Hill, Ontario. The new survey also covered Claim 170866 located in the southeast corner of the East Sheet.

The new survey lines are 100 m apart, with pickets established at every 25 m. Altogether 27.6 1. km of magnetic and 25.1 1. km of VLF-EM surveying were needed to cover the claims.

4.2 Survey Specifications

The total magnetic field was observed along the survey lines and the base line at 12.5 m intervals using the EDA OMNI PLUS proton precession magnetometer, expect in Claim K 1079866, where the observation interval is 25 m. The diurnal and day-to-day variations of the magnetic field were monitored and recorded by the EDA OMNI 4 base station magnetometer system located near the property. The magnetic observations were corrected for these variations and a constant was applied to the corrected values of the new survey for merging with the previous data.

The EDA OMNI PLUS instrument was used to measure the in-phase and quadrature component of the VLF-EM magnetic field at stations 12.5 m apart; as above the station interval was 25 m in Claim K 1079866. The primary electromagnetic field was provided by the VLF transmitter (NLK) located at Seattle, Washington, operating at a frequency of 24.8 kHz.

4.3 Data Compilation and Presentation

The geophysical data are presented on copies of base maps (East and West Sheets) at a scale of 1:2 500 showing the survey lines, stations, major planimetric features and the locations of previous drill holes.

As noted above the magnetic data were corrected for diurnal variations and were merged with the previous data set. The data are presented in two formats: (a) as postings of the magnitude of the magnetic field at the stations, less 60 000 nT and (b) as contours of the total magnetic field. The contour interval is 20 nT with suitably larger intervals where the gradients are steep.

The VLF-EM results are shown as profiles of the in-phase and quadrature components (the vertical scale is 1 cm = 2056) and as contours of the filtered (Fraser filter) in-phase component. A constant was applied to the filtered values for merging with the previous filtered data set.

4.4 Discussion of the Results

4.4.1 General Comments

The magnetic domains shown on the Interpretation Maps were outlined on the basis of uniformity of certain magnetic characteristics which include background, strike, length and width of the anomalies etc. The indicated "limits" of the magnetic domains does not necessarily demark a geological contact, but it intends to depict a zone where the magnetic behaviour of a rock assemblage changes sufficiently to produce recognisable magnetic signatures. Individual magnetic bodies are also be outlined within the domains. Altogether 16 domains were outlined, but many of them have similar magnetic characteristics.

The amplitude of the in-phase component was used to classify the responses as "well defined", "mediocre" or weak. Six different types of VLF-EM conductors are indicated:

(a) the rarest one is the conductor which is in direct correlation with magnetic anomaly, the example is Conductor V1,

(b) there are a number of conductors which are at or near the indicated limit of a magnetic body indicating a conductive contact, like Conductors V2 and V3,

(c) Conductors V4 and V5 are examples of features which are found near limits of magnetic domains, possibly suggesting conductive contacts,

IIIIIIIIIIIIIIIIIII

(c) edges of flat laying conductive sheets, like edges of swamps, conductive lake bottom sediments are believed be indicated by Conductors V6, V7 and V8,

to

(d) the majority of the conductors (examples: V9, V10, V11 and V12) are subparallel to the stratigraphy indicated be the magnetics and may indicate conductive strike shears and/or contacts and

(e) conductors which are transgressive to the stratigraphy.

The interpreted shear zones and/or faults which are shown on the Interpretation Maps were outlined based on magnetic and VLF-EM signatures on the disruptions of the magnetic patterns and disruptions of the filtered in-phase contours (magnetic, VLF-EM or magnetic-VLF-EM support).

4.4.2 Detailed Discussions

As noted earlier the property is within metavolcanic Warclub Group belt, which is metasediments to the north and the south. The as discussed below suggest that the! felsic assemblage may include magnetic felsic intermediate to mafic composition volcanics in together with metasediments and mafic dykes possible intermediate to basic intrusions.

the felsicbordered by

magnetic datametavolcanicvolcanic orthe sequence

(diabase) and

Magnetic Domain A situated along the southern perimeter of the claim group extending towards the south is characterised by low magnetic background and by a few low amplitude anomalies, with the exception of Anomaly A1 depicting an interpreted diabase dike. The domain may represent non-magnetic felsic metavolcanics or interbedded metasediments and volcanics. The logs of Holes LB-01-01, LB-01-02, LB-01-03, LB-01-06, LB-87-2, LB-87-03 and LB-87-4 could shed light on the rocks underlying Domain A on the Eastern Sheet. The relatively small Domain R in the south-central part of Domain A is could very well depict a small, more magnetic intrusion.

Domains B and C located on the Western Sheet cover zones of low magnetic background, including low amplitude, generally narrow magnetic anomalies. There is a suggestion that Domain C could indicate a folded member. Its is suggested that the domains are underlain by felsic metavolcanic rocks. The magnetic field is relatively inactive within Domains D, E and E? on the Eastern Sheet, but the magnetic backgrounds are noticeably increased compared to Domain A to the south. Somewhat more magnetic volcanic rocks of the sequence may be depicted.

The largest Domain F occupies the north central parts of both sheets. The magnetic background is elevated and numerous, nearly east-west striking, mostly narrow, often long strike length anomalies should indicate the more mafic members of the metavolcanic sequence. Anomaly F1 is a magnetic low of about 2000 nT amplitude. Anomalies of this shape and its large amplitude below background could indicate rocks having ruminant magnetization, differing in magnitude and direction from the magnetization produced by the present magnetic field. The above anomaly would imply ruminant magnetization opposing the present day field. Anomaly F2 is believed to show a mafic dyke (gabbro or diabase).

The domain also includes several of the large amp!itude, well defined VLF-EM conductors, depicting shallow seated events. Conductors V2, V3, V13, V14 and V15 are singled out because of their close association or correlation with magnetic features demarking the contact or suggesting minor contributions from conducting magnetic mineralization.

The incomplete Domain G in the northwest corner of the West Sheet exhibit lower magnetic background. The significant features of the domain are the northeast striking subparallel Anomalies G1 and G2. Anomaly G1 cover well defined and more dubious, narrow magnetic lows which could represent rocks with ruminant magnetization opposing the present day field. Anomaly G2 indicates rocks with induced magnetization. The strike of both anomalies is uncertain because of the marked variations of the magnetic properties of the rocks along the perceived strikes. Significantly, Conductor V1 is in direct correlation with Anomaly G1 and both deserve further attention.

Domain H in the centre of the West Sheet characterised by large amplitude anomalies of which H1 is noted having an amplitude in excess of 5 000 nT. If the significant magnetic low south of the peak is part of the anomalous signature to the north then a flatly north dipping body is implied. However, the intense magnetic low, together with Anomaly H2 could demark rocks with ruminant magnetization. It is suggested that the domain represent a mafic intrusion or mafic volcanics.

The east-west striking Domains I and J are similar in character enclosing areas of low magnetic background with anomalies showing considerable strike length. Felsic to intermediate metavolcanics may be the sources. The lenticular Domain L in the east central portion of the West Sheet stands out with its elevated background and relatively low amplitude anomalies. The domain could indicate intermediate intrusives or metavolcanics.


The southern margins of both sheets, north of Domain A is occupied by the distinct Domain K. The basic characteristics of the domain change somewhat east of the northwest trending 31, where the domain widens and the number of anomalies within the domain is also increased. Within the western part, the somewhat wider anomalies may reflect the greater depth of burial of the interbedded felsic to intermediate metavolcanics and possibly sediments which could underlay the domain.

The strike of Domain M is anomalously northwest, transecting the normally east-west striking stratigraphy. The domain is the northwesterly extension of Anomaly A1 and the enclosed anomalies are believed to indicate mafic intrusives. Anomaly M1 is noteworthy as it may represent rocks with ruminant magnetization. If Anomaly F2 is a continuation of the mafic intrusion then movements along Faults S2 and S3 are envisaged.

Somewhat elevated backgrounds sets apart Domain N which can indicate intermediate to basic metavolcanics. The incomplete Domain 0 is along the southern perimeter of the East Sheet, bordering Domain A. The increased magnetic background and activity suggests basic to intermediate composition volcanics.

Two partial magnetic anomalies and minor VLF-EM conductors were defined in Claim 1079866.

It was noted earlier that VLF-EM and magnetic surveys afforded the delineations of numerous interpreted faults and /or shear zones. The dominant directions of shearing or faulting are east-west as noted by the VLF-EM conductors, northwest- southeast and northeast-southwest.

5.0 CONCLUSIONS AND RECOMMENDATIONS

The ground magnetic data collected over the claims suggest that the magnetic characteristics of the underlying rocks is more variable than the general geologic information would suggest.

Altogether 16 magnetic domains were outlined of which Domains A, B, and C may be underlain by mainly felsic metavolcanic and /or meatsediments. Domains G, I, J and K exhibit lower magnetic background and a varying complexity of the enclosed anomalies is evident. The suspected sources include felsic to intermediate metavolcanics possibly interbedded with sediments. The backgrounds have markedly increased in Domain E, D, F, H, L, N and O suggesting more abundant contribution from more magnetic, mafic(?) rocks in the assemblage. Domain P could very well be caused by a felsic to intermediate intrusive. It is believed that Domain M and Anomalies A1 and F2 are demarking mafic dykes (diabase or gabbro). Large amplitude magnetic lows suggests that the metavolcanic

8

sequence include rocks which could have sizeable magnetization opposing the present day field.

reminant

The VLF-EM survey detected numerous conductors which are believed to be originating from current gathering rather than being caused by induction. However, there are locales where direct correlation between the magnetic and VLF-EM responses suggest magnetic sulphides may also have contributed to the overall electromagnetic response e.g. Conductors V1 , V13, V14, V15 and V16. It is suggested that the majority of the conductors are caused by conductive strike shears and contacts along which conductive sulphides may also have accumulated.

The disruptions of the magnetic and VLF-EM patterns allowed the delineation of faults and/or shear zones some of which can be traced across the grid. The main directions of the interpreted structural deformations are northwest, northeast and east-west of which the northwest-southeast structure are subparallel to the main deformation of the general area, Pipestone-Cameron Fault.

It is recommended in the first instance that if the geologic logs of; the previous holes are available a detailed correlation between the geology and the geophysical signatures should be prepared. In order to validate the results of this interpretation, and to aid the selection of locales for further investigations, the results of the field mapping being conducted presently will have to be integrated with the geophysical data. It is recommended that induced polarization surveys should be part of the further investigations, which could be concentrated at locales where magnetic and VLF-EM signatures correlate, like V1, V14 and V15 or in the vicinity of intense structural deformation implied by intersecting structures within favourable stratigraphy.

DescriptionThe "OMNI PLUS" geophysical system combines the OMNI iv Tie-Line" magnetometer and jradiometer together with a VLF neasurement capability.The OMNI PLUS VLF/Magneto- neter System has been develop ed in co-operation with ceo- Dhysical Surveys inc. of Quebec, :anada.rhis brochure concentrates on :he VLF magnetic and electric :ield parameters measured and •ecorded by the OMNI PLUS. More nformation on the OMNI PLUS nagnetometer system and tie- ine capability is available in the DMNIIV brochure.

Features•ach OMNI PLUS incorporates the Allowing features:

Measurement and recording in memory of the following VLF data for each field reading:• total field strength,• total dip,• vertical quadrature or, alternately, horizontal amplitude,

• apparent resistivity,•phase angle,• time,• grid co-ordinates,• direction of travel along grid

lines, and• natural and cultural features.Complete data protection fora number of years by anInternal lithium backupbattery."Tie-Line" or "Looping"algorithm, unique only toEDA'S OMNI IV and OMNI PLUSSeries, for the self-correction of atmospheric variations and variations in the primary field from the VLF transmitter.

• Measurement of up to three VLF transmitting stations to provide complete coverage of an anomaly regardless of the orientation of the survey grid or of the anomaly itself.

• Display descriptors to monitor the quality of the VLF signal being measured.

• Choice of three data storage modes:- spot record, for readings without grid co-ordinates

- multi record, for multiple readings at one station

- auto record, for automatic update of station number

• output of grid co-ordinates with the designated compass bearing, using N, S, E, W descriptors.

Major Benefits• combined VLF/Magneto-

meter/Cradiometer SystemThe OMNI PLUS Incorporates the capabilities of the OMNI iv "Tie- Line" Magnetometer and cradiometer system with the ability to measure the VLF magnetic and electric fields.Oniy one OMNI PLUS is needed to record all of the following geophysical parameters:

1. The total magnetic field2. The simultaneous gradient of

the total magnetic field3. The VLF magnetic field,

including:- the total dip- the total field strength of the VLF magnetic field

- the vertical quadrature, or alternately, the horizontal amplitude

4. The VLF electric field, including:- the phase angle- apparent resistivity

AS an example, at each location the OMNI PLUS can calculate and

record in a matter of seconds, three VLF magnetic field and two VLF electric field parameters from two different transmitters, a magnetic total field reading and a simultaneous magnetic gradient reading.

• No orientation RequiredThe OMNI PLUS requires no orientation, by the operator, of the sensor head toward the transmitter station. This simplifies field procedures as well as saving considerable survey time. When two VLF transmitters are measured, the benefits of this time-saving feature are auto matically doubled. There is no requirement for the operator to orient himself and the sensor head toward the first selected transmitting station and then re orient towards the second trans mitting station.Consistent high quality data is achieved In the OMNI PLUS due to the utilization of three ortho gonal sensor coils rather than two sensor colls used in conventional systems. The quality of data Is not then dependent on the operators ability to correctly orient the sensor head for optimum coupling with the transmitting station.The OMNI PLUS compensates automatically for the direction of travel along the grid lines as well as for the angle of the sensors from the vertical plane through the use of tiltmeters.

quadrature. The OMNI PLUS i calculates each of these I parameters from the !n-phase I and quadrature measurements

of all three components.

!• Automatic calculation of Fraser FilterThe OMNI PLUS automatically calculates the Fraser Filter, from the dip angle data, regardless of the interval between the stations along the grid lines. The operator no longer has to manually per form this mathematical calcula tion thereby reducing the pos sibility of human error. The Fraser Filter algorithm follows es tablished conventions.The operator can choose to out put either the total dip or the Fraser filtered data, or both.

Calculation of ElllptlcltyThe OMNI PLUS calculates the true ellipticlty of the VLF magnetic field from the measurement of the in-phase and quadrature of all three components. The ellipticity provides more interpretative information about the anomaly than the dip angle and is less Influenced by over burden shielding.

I » Automatic Correction of Primary Field variationsThe OMNI PLUS can be used as a base station to monitor primary field changes from up to three VLF transmitters as well as alternately measuring the variations in the magnitude of the earth's magnetic field, only one OMNI PLUS is needed to perform both functions.The OMNI PLUS base station can then automatically correct, by linear interpolation, the field units for these drift variations in the primary VLF and total magnetic fields.

• Measurement of VLF Electric FieldThe OMNI PLUS calculates and records the apparent resistivity and phase angle from the measurement of the VLF electric field. This VLF electric field measurement can be accomplish ed by using capadtively or resistively coupled electrodes at spacings of 5,10 or 20 meters.

Other BenefitsAutomatic TuningThe OMNI PLUS automatically tunes up to three VLF trans mitters within a frequency r; nge of 15 to 30 kHz, once the operator has programmed in the specific frequencies.

• Base station SynchronizationThe OMNI PLUS has a unique "count-down" feature which can be activated in the field unit upon synchronization with the base station. The field unit then displays and decrements the re maining time, In seconds, until the base station Is scheduled to take a measurement. The operator can obtain a field reading at exactly the same time as the base station. The sim ultaneous field and base stat.on measurements significantly in- prove the automatic correction accuracy.

• Automatic "Tie-Line" correctionThe OMNI PLUS can automatically correct by Itself the VLF field data for atmospheric variations and changes in the primary field originating from the VLF transmitter. By tieing-back into one or several tiepolnts on the grid, the OMNI PLUS will

automatically calculate and apply the drift measured to the field data previously recorded In memory. More Information on this unique "tie-line" method can be obtained from page 3 of the OMNI iv brochure.

• Notation of Natural and Cultural FeaturesThe OMNI PLUS can record natural and cultural features unique to each grid location. This capability eliminates the need for a field notebook and provides additional Information that can assist In interpreting recorded data.

• Analogue outputSince VLF as well as magnetic data is often easier to interpret as a profile plot, data collected by the OMNI PLUS can be represented in analogue format at a vertical scale best suited for data presentation. The operator can selectively output in analogue and/or digital format, up to 10 of the following parameters:- total dip-Fraser filtered data- ellipticity-VLF total field strength- vertical quadrature- horizontal amplitude- apparent resistivity- phase angle- magnetic total field strength- magnetic vertical gradient

• Computer interfaceThe OMNI PLUS can transfer un- corrected, corrected or filtered data to most computers with a RS232C port, in some cases, a DCA-100 Data Communications Adaptor may be required. Computers with collection packages Including either "X-ON,X-OFF"or"ENQ/ACK"communications protocol formats are also compatible.
