OPAP FINAL REPORT WOOLLEY LAKE CLAIMS EDWARDS TWP. ONTARIO
1.0 INTRODUCTION
This report describes the results of prospecting, VLF-EM ,
magnetometer and geological mapping surveys carried out from
June 19 to July 26, 1993 by the writer on the Wooiley Lake Claims
located in Edwards Township, Ontario. This work was funded by the
Ontario Prospectors Assistance Program (OPAP), File Number
OP93-028. The writer was assisted in the field by E. Benham. The
results of this program are presented on Maps I to 4 at a scale of
l" = 200' .
2.0 PROPERTY. LOCATION and ACCESS
The Wooiley Lake property consists of two claim blocks,
L.1187113 of 12 units and L.1187114 of 8 units, for a total of 20
claim units. The claims were recorded on February 3, 1993 in the
name of Wayne Russell Benham. The property is -located in the
central portion of Edwards Township in the Larder Lake Mining
Division about 10 kilometres north of the Town of Iroquois Falls
(Claim Map Sheet G-3496, NTS: 42 A/15, Latitude 48 0 51' Longitude
80 : 38', Figures l S 2).
Access is by the Detour Lake Road leading northwards from
Iroquois Falls to Kilometre Eight, east for 2.0 km and then north
for 0.4 km along Abitibi Paper Company Ltd. logging access roads.
Except for outcrop areas, the property has been logged of within
the last five years and partially reforested.

Since adequate accommodations could not be found in the
Iroquois Falls area, the writer travelled daily to the property
by car from Tarzweil, Ontario and the home of L.M. Dyment and
J. A. Kidston whose kind hospitality was greatly appreciated. The
round trip distance to the property and back to Tarzweil is 264 km.
3.0 GEOLOGY
Edwards Township is underlain by Archean sedimentary and
volcanic rocks which are intruded by diabase dykes and gabbroic
stocks.
The volcanics consist of felsic ash to lapilli tuffs and mafic
flows. The sediments consist mainly of graywackes with interbedded
volcaniclastics, siltstones and graphitic argiilites. The
sediments and volcanics strike N20 3E to N40 : E and are steeply
dipping. The diabase dykes are associated with the north northwest
striking Timiskaming Lake structural zone.
Previous drilling and surface trenching during the 1960's in
the west-central portion of Edwards Township, discovered semi-
massive pyrite and pyrrhotite with geochemically anomalous nickel,
copper and zinc contents.
4.0 PREVIOUS WORK
Research of the Kirkland Lake Assessment Files for Edwards
Township showed that the township was flown by Canadian Aero
Mineral Surveys for Canadian Javelin Ltd. in 1964. An extensive
zone of bedrock conductivity with magnetic correlation was located
Page 4
to the west of Wool ley Lake. During 1965 Canadian Javelin Ltd.
carried out horizontal loop EM, magnetic and geological mapping
surveys to explore this conductive zone. Subsequent drilling
intersected semi-massive sulphides in graphitic sediments, altered
felsic volcanics and gabbroic intrusives. Geochemically anomalous
copper, zinc and nickel assays ( up to Q.13% Cu, Q.14% Zn and
Q.10% Ni ) were reported.
Survey lines were cut north-south at an acute angle to the
strike of the volcanics. Therefore, it appears that the ground
electro-magnetic survey was not interpreted correctly. The strikes
of the magnetic anomalies, which correlate closely to the strike of
the volcanics, are almost perpendicular to the interpreted strikes
of the EM conductors. The Canadian Javelin holes were drilled along
the strike and down the dip of the volcanics. Although the holes
intersected conductive graphite and sulphides with anomalous
basemetal assays, the strongest conductor probably was not tested
due to the improper orientation of the drilling.
In 1964, Inco drilled a hole which was located approx
imately 1.5 km to the north along strike of the Canadian Javelin
conductors. The Inco hole intersected semi-massive sulphides but
no assay results were reported.
Edwards Township was flown in I960 by Amax and Cominco however
both these companies followed up anomalies to the north and south
of the current Wooiley Lake claims.
During 1988, an airborne electromagnetic and total intensity
magnetic survey of the Detour-Burntbush-Abitibi area was flown by
Geoterrex Ltd. for the Ontario Geological Survey. Map No. 81240,
which covers most of Edwards Township, shows similar EM and
Page 5
magnetic anomaly patterns as the Canadian Javelin airborne survey
but in greater detail.
5.0 WORK POKE
Only 24% of the work was done on claim L. 1187114 while 76% of
the work and all of the sampling were done on claim L. 1187113.
5.1 Prospecting
The property was prospected for five days from June 19th to
23rd inclusive by the writer and field assistant E. Benham. The
main purpose of this work was to locate the previously reported
sulphide showings, confirm the interpreted strike of the volcanic
rocks and locate the starting point for the proposed grid. Four
grab samples (Nos. 88901 to 88904) were collected and assayed for
Au, Ag, Cu, Pb, Zn and Ni. (See Table l for prospecting log and
Figure 3 for prospecting sample locatons).
5.2 Linecutting
A 10.01 mile grid was cut July l to July 8, 1993 under
contract by Thomas Obradovich of Kirkland Lake. The western part
of the grid consists of a baseline, starting at post No. l of claim
L 1187113, at 030 : Az and cross lines at 400 foot intervals from
4+00 S to 36+00 S with pickets every 100 feet. The eastern part of
the grid consists of baseline 28+00 S at 1200 Az and cross lines at
800 foot intervals from 00+00 to 32+00 E with pickets every 100
feet.
The location of the grid with respect to the claim boundaries
and topographic features is shown on Figure 2.

5.3 VLF-EM Survey
The VLF-EM survey was carried out by the writer from July 10
to 13, 1993 with a Crone Radem VLF-EM unit. The dip angle in
degrees of the magnetic field component from the horizontal was
measured. The number of readings taken at 100 foot intervals was
514. For the western part of the grid, the transmitter station
used was Annapolis, Maryland which operates at a frequency of 21.4
KHz. The eastern part of the grid was surveyed using transmitter
station Seattle, Washington which operates at a frequency of 18.6
KHz. The instrument specifications are listed in Appendix I.
5.4 Magnetometer Survey
The magnetometer survey was carried out by the writer from
July 14 to 17, 1993 using a Barringer proton magnetometer. Model
GM-122. This instrument measures the earth's total magnetic field
to an accuracy of l gamma. Additional specifications are given in
Appendix I. Diurnal variations were monitored by establishing base
stations and completing hourly closed survey loops. A total of 984
readings were taken at 50 to 100 foot intervals depending on the
magnetic gradients along the surveyed lines.
5.5 Geological Mapping
The property was mapped by the writer and field assistant
E. Benham from July 18 to July 26, 1993 by traversing the grid
lines. Traverses between the grid lines were made in the vicinity
of any sulphide showings. The outcrops located in the south
western portion of claim L. 1187113 were not covered by the cut
picket line grid. These outcrops were mapped by a pace and compass
Page 9
line at 48+00 S from baseline 0+00 to the western claim boundary.
Twenty-two grab samples (Nos. 5057 to 5064, 13589 to 13600)
were collected and assayed for Au ppb, Cu ppm, Ni ppm and Zn ppm.
Two samples (Nos. 13592 and 13598) were assayed for Pt ppb and
Pd ppb. Whole rock analysis were completed for samples 5058, 5063,
13590 and 13593.
6.0 EXPLORATION RESULTS
6.1 Prospecting
Prospecting traverses in the western portion of claim
L. 1187113 found the volcanic and sedimentary rocks to strike 205:
to 215' Az. Only intrusive rocks, i.e. diabase and gabbro, were
located in the central eastern part of claim L. 1187113 and no
outcrop was found on claim L. 1187114. However, the airborne
magnetics for the area indicate that the strike of the underlying
formations is 120 3 Az in the eastern part of the property.
In the northwestern part of claim L. 1187113, disseminated
pyrite and pyrrhotite were discovered in finely bedded siliceous
volcaniclastic sediments. The sediments are intruded by irregular
narrow, l" to 6", blue-white quartz veins. These sulphide showings
are located to the north of the previous work reported by Canadian
Javelin. Three grab samples (Nos. 88901 -88903) of the sulphide-
bearing material and one grab sample (No. 88904) of the quartz
veins were collected and assayed. Samples of the sulphides were
weakly anomalous in nickel and zinc. All four samples assayed Nil
gold. The sample locations are shown on geology Map l and the
results are listed in Table 2.
Page 10
As a result of the prospecting work it was decided to
establish a picket line grid with a baseline at 030' Az in the west
and a baseline at 120 3 Az in the east to investigate a possible
synclinal fold structure.
6.2 Geological Mapping
The Wool ley Lake property is underlain by Archean volcanic and
sedimentary rocks which are intruded by related gabbroic masses,
granodiorite and Matachewan diabase dykes. No outcrop was found on
the eastern claim block L. 1187114 where the overburden consists of
wet clay deposits in the southwest part of the claim and sand
plains to the northwest. On the western claim block L. 1187113
four outcrop areas were located. Each area is marked by a
prominent hill which is due to a diabase dyke. The results of the
geological mapping are shown on Map l at a scale of l" = 200'.
6.2.1 Sedimentary Rocks
The sedimentary rocks consist of graywackes, siltstones,
argillites and volcaniclastics intercalated with minor associated
felsic to intermediate pyroclastics.
The graywackes and siltstones are grey-green, fine to medium
grained and massive to finely bedded. The argiliites are black,
carbonaceous, pyritic and finely laminated. They occur as large
3'x 2' xenoliths in the gabbro intrusives at 2 + 00 E to 3 + 00 E
along line 28+00 S.
The volcaniclastic rocks consist of thickly bedded units with
lapilli of sedimentary and felsic volcanics in a fine grained
biotitic graywacke matrix. The most dominant ciasts are resistive
Page 11
sub angular, fine grained, dark grey, felsic lapilli up to 0.5"
wide.
6.2.2 Volcanic Rocks
The volcanic rocks consist of fine grained, dark green to grey
green, massive to well pillowed basalts with associated pillow
breccias and hyaloclastites. The pillowed lavas are best exposed
along the eastern edge of the outcrop hill at 48+00 S.
6.2.3 Intrusives
Three, 100'to 200' wide, northerly striking, nearly vertically
dipping, diabase dykes cut the volcanic and sedimentary
stratigraphy. The diabase is brown weathered, dark green, medium to
coarse grained and moderately to strongly magnetic.
A large gabbro mass is located 200' to 400' to the east and
west of the diabase dyke on line 28+00 S between 00+00 and 8+00 E.
The outer limits of this body is unknown. The gabbro is medium
grained, dark green, massive, weakly magnetic and locally dioritic.
Minor granodiorite intrusives are located along lines 20+00 S
and 28+00 S to the west of a diabase dyke. The granodiorites are
black and white, biotite * hornblende * feldspar * quartz, massive
to schistose, medium grained intrusives.
6.2.4 Structure
The volcanics and sediments strike 1803 to 215 : Az in the
western part of the property and are interpreted from the magnetic
and VLF-EM results to strike 120" Az in the eastern claim block.
The sedimentary rocks are steeply dipping at 80 3 to 85 : to the east
Page 12
and west. The pillow lavas indicate stratigraphic tops to the
east. The volcanics and sediments probably are folded synclinally
with a fold axis striking 075: Az.
Two shear directions were noted during the survey. The first
is located to the west of the diabase dyke on line 28+00 S where
narrow shears zones strike ISO 3 Az and dip 80 : to the east. Blue-
white, I" to 18" wide, quartz ladder veins are associated with
these shear zones. The second set of shears strikes 295 : Az and
dips 80 ; to the north as seen at 24 + 00 S, 14 + 00 W. These shear
zones contain graphitic, pyritic, banded white quartz veins.
6.2.5 Mineralization
A total of 24 grab samples were collected during the mapping
and prospecting surveys. Sample locations are shown on Map I and
the results and sample descriptions are listed in Table 2.
Siliceous sulphide - rich sediments and volcaniclastic rocks
were found on line 12+00 S at 8+00 W to 12+00 W, 20-00 S at 21+00
W and 26 + 00 S at 10 + 50 W to 14 + 00 W. The sulphides consist of
trace to 5%, finely disseminated to wispy 0.1" wide pyrrhotite
lenses and trace to 2% finely disseminated pyrite. Samples of the
sulphide mineralization returned geochemically anomalous nickel
assays of up to 503 ppm Ni.
Sample 13596 from the graphitic, pyritic shear zone at 26+00
S, 14+00 W assayed 327 ppm Cu, 232 ppm Ni and 425 ppm Zn.
The pyritic carbonaceous argillite xenoliths, located along
line 28+00 S, assayed up to 127 ppm Cu, 197 ppm Ni and 173 ppm Zn.
All samples, including samples of the blue-white quartz veins,
assayed Nil to trace gold.
Page 13
6.2.6 Whole Rock Analysis
Whole rock analyses were completed on four representative
samples of the fine grained to coarse grained volcaniclastic
sediments. The results show these rocks to be alumina-rich and
silica-poor. See report no. M 2691 on following page for the
complete whole rock analyses results.

6.3 Magnetometer Survey
The contoured magnetic results are plotted on Map 2 at a scale
of I" = 200'. The anomalies of interest are labelled A to G.
The magnetic patterns are complicated by the northerly
striking strongly magnetic diabase dykes which intrude pyrrhotite -
bearing volcanics and sediments. The diabase outcrops produce
magnetic dipole effects along their contacts which usually mark the
edges of the prominent outcrop ridges.
In the western part of the grid, 50 to 250 foot wide, 500 to
2500 gamma, linear magnetic anomalies (A to E) have a predominant
strike of 030' Az. These anomalies are interpreted to be due to
disseminated to massive pyrrhotite zones.
Anomaly F is 100 to 1200 feet wide and at least 2400 feet
long. This 1000 to 3500 gamma magnetic anomaly has a linear
southern contact and a convex northern boundary, i.e. a half moon
shape. It may be due to a northerly dipping disseminated to
massive pyrrhotite lens, a buried magnetic gabbroic body or
possibly an irregular shaped kimberlite pipe(?). There is no
outcrop in the area of this anomaly. The weakly anomalous eastern
strike extensions of VLF-EM anomalies D and E' appear to be
associated with this magnetic anomaly.
Anomaly G is poorly defined because of the widely spaced grid
lines. This 2000 foot diameter, roughly circular, 100 to 450 gamma
anomaly is centred on a 700 foot circular bog at 16+00 S on line
8+00 E. The source of this anomaly may be a gabbroic stock or a
kimberlite pipe(?).
Page 19
6.4 VLF-EM Survey
The VLF-EM dip angles are shown in profile on Map 3 and the
Fraser Filtered dip angles are contoured on Map 4. The scale of
both maps is l" = 200".
The VLF-EM results show seven subparailei weakly conductive
horizons, labelled A to K on the maps, which strike 010 : to 030 3 Az
in the west and I20 : to 135" Az in the east. Contouring of the
results in the west is influenced by northerly striking diabase
dykes which interrupt the continuity of the conductivity along the
mineralised horizons. The strongest conductor F* is located at
13 + 00 W on line 28+00 S. Disseminated and narrow l" to 2" wide
bands of semi massive pyrrhotite and pyrite were found along strike
of this anomaly. No outcrop was located in the vicinity of the
interpreted northern strike extension of the conductor F-F* at
18+50 W on line 16+00 S.
A moderately strong conductor E 1 is located at 10+00 S on line
8+00 E. This conductor is flanked to the south by a strong 900
gamma magnetic anomaly. There is no outcrop in this area.
At 20+00 S on baseline 0+00, a moderately strong conductor was
detected, but again no outcrop was found.
The VLF-EM anomalies in the eastern portion of the grid are
very weak possibly due to the depth of overburden.
7.0 CONCLUSIONS and RECOMMENDATIOHS
Previous drilling in the area reported sulphide mineralization
associated with rhyolite lapilli tuffs; however, the recently
completed mapping found the fragmental rocks which are exposed in
Page 20
outcrop to be volcaniclastic sediments.
Samples of the pyrrhotite-rich sediments returned geo
chemical ly anomalous nickel contents. Although no ultramafic rocks
were found in outcrop, previous drilling reported intersecting talc
* carbonate * serpentinite rocks. The geological setting of the
Wool ley Lake claims may be similar to the geology of the Redstone
Nickel Deposit located in Eldorado Township to the south of Timmins
(Fyon, J.A. et al, pgs. 45 to 49).
Some unexplained VLF-EM and magnetic anomalies were located by
the geophysical surveys. Of particular interest are magnetic
anomalies B-B', C-C', F and G and electromagnetic anomalies F-F',
E-E', C', A and G.
The Wool ley Lake claims have some potential for the discovery
of nickel * copper disseminated to massive sulphide deposits
associated with komatiitic volcanics or gabbroic intrusives. Also
the magnetic results indicate that there may be some potential for
the discovery of kimberlite pipes associated with faults intruded
by the diabase dykes. These faults are located within the
TirTi.iskaming lake structural zone.
A horizonal loop electromagnetic survey is recommended to
further investigate the VLF-EM and magnetic anomalies on lines 8-rCO
S to 32+00 S and 0+00 to 32+00 E. Depending on the results of the
horizontal loop survey, induced polarization survey of lines 8+00
E to 24+00 E also should be considered to search for disseminated
versus massive sulphide basemetal deposits.

This is a rugged, simple to operate, ONE MAN EM unit. It can be used without line cutting and is thus ideally suited for GROUND LOCATION OF AIRBORNE CONDUCTORS and the CHECKING OUT OF MINERAL SHOWINGS. This instrument utilizes higher than normal EM frequencies and is capable of detecting DISSEMINATED SULPHIDE DEPOSITS and SMALL SULPHIDE BODIES, it accurately isolates BANDED CONDUCTORS and operates through areas of HIGH HYDRO NOISE. The method is capable of deep penetration but due to the high frequency used its penetration is limited in areas of clay and conductive overburden.
The DIP ANGLE measurement detects a conductor from a considerable distance and is used primarily for locating conductors. The FIELD STRENGTH measurement is used to define the shape and attitude of the conductor.

PARAMETERS MEASURED:
(1) DIP ANGLE in degrees of the magnetic field component, from the "horizontal, of the major axis of the polarization ellipse. Detected by a minimum on the field strength meter and read from an inclinometer with a range of 90* and an accuracy of Vi 0 .
(2) FIELD STRENGTH (total or horizontal) of the magnetic component of the VLF field, (amplitude of the major axis of the polarization ellipse). Measured as a percent of normal field strength established at a base station. Accuracy 2*34* dependent on signal. Meter has two ranges: O 300^o and O 600*^.
(3) OUT-OF-PHASE component of the magnetic field, perpendicular in direction to the resultant field, as a percent of normal field strnegth, (amplitude of the minor axis of the polarization ellipse). This is the minimum reading of the Field Strength meter obtained when measuring the dip angle. Accuracy 1207o.
