1. LOCATION
The property on which work was carried out under the
above registration comprises 77 claims, patents and leases in the
Slate Bay Area, McDonough and Dome Townships of Red Lake Mining
Division (Fig. l).
2. SYNOPSIS OF WORK COMPLETED
Bluestack Resources Limited continued exploration on its
property in McDonough and Dome Townships in the Red Lake Area of
Ontario. Work this year involved soil geochemical surveys of the
total land area of the property with samples taken every 50 ft. on
lines 400 ft. apart. In some areas a closer spaced line interval
was used. Basal till sampling was undertaken over some coincident
geochemical and geophysical anomalies on land while E.M. conductors
under Red Lake were investigated by sampling from the ice during
late winter 1982. Geological mapping was carried out using the
grid as above and a comprehensive geological map produced. The
locations of diamond drill hole collars were ascertained where
possible and a plan prepared showing the location of all the drilling
undertaken on the property from 1937 to 1967 (Map 11).
3. GEOCHEMISTRY
The long strike extent of the E.M. anomalies and the broad
magnetic anomalies required that some additional work be carried out
in an effort to more advantageously select drill targets. As base
metals were known to be associated with some of these anomalies geo
chemistry was utilized. The off-shore anomalies under the waters of
Slate Bay were investigated by basal till sampling while a soil
- 2 -
survey was carried out on the land section of the property. This
in turn was followed up by basal till sampling.
3.1 Soil Survey
A total of 1962 samples was collected by grub hoe and auger
from beneath the organic rich soil horizon. All samples were analysed
for Cu, Pb, Zn, Ag and Au. Results are presented on Maps l, 2, 3,
and 4. Statistical treatment of the data was undertaken for Cu, Pb
and Zn only as the data for Ag was uniformly low and Au data is in
complete due to insufficient sample in some instances allowing only
a detection limit of 50 ppb. However taking this restriction into
account anomalous values were encountered and the map is useful.
The statistical data for Cu, Pb and Zn is as follows:
Cu
ppm
M 9
M+S 20
M+2S 34
M+3S 47
The results have been colour coded using the above as a
guideline and the colours display the anomalous areas clearly.
Geological mapping (Map 10) shows large areas of overburden which
will obviously reduce the geochemical response of sub-outcropping
mineralization. These overburden areas are also indicated by the
E.M. map (Map 8) so that a lack of geochemical response within these
areas is expected.
As noted above the purpose of the geochemical survey is to
seek positive indications of mineralization. Where such a positive
indication coincides with a good geophysical response then such an
area is deemed a prime drill target. The absence of geochemical
response in an area of geophysical response may be solely a factor
of increasing overburden depths.

3.2 Basal Till Sampling
The basal till sampling comprised two programs, one from
the ice on Red Lake in early 1982 and a program on land during
summer 1982.
The program from the ice was designed to investigate a
series of parallel E.M. anomalies located to the south of the Slate
Bay Peninsula and under the waters of Red Lake. A total of 282 holes
was drilled for the recovery of 230 samples. Sample loss occurred
where no basal till was developed and unconsolidated lake sediments
immediately overlie bedrock. In some instances rock samples were
recovered and again two of these showed visible sulphides - pyrrhotite
and pyrite. A total of 3,452 metres (11,250 ft.) was drilled with
2,312 metres (7,540 ft.) in overburden and the balance of 1,140 metres
(3,710 ft.) in water. This gives mean hole of 12 metres (40 ft.)
with 4 m (13 ft.) in water and 8 m (27 ft.) in overburden. Samples
were analysed for Cu, Zn, Ag and Au and the results of this program
are shown on Maps 5a, 6a k 7a. These show sporadic high values for
Zn which are highly anomalous against the general background. Two
values of note occur at the southern end of the sampling grid where
zinc values of 230 and 910 ppm occur 200 ft. apart. The 910 value
is open to the south and has a coincident 210 ppm Cu. These values
are associated with E.M. anomalies 'J 1 and 'K' (Map 8).
The onshore basal till program was undertaken to investigate
the surface geochemical anomalies near E.M. anomalies associated with
mineralization known to exist on claims 2206 k 2208. Trenching in
this area in late 1981 showed the presence of significant Ag, Cu and
Au values while drilling in 1962 had indicated the persistence of
this mineralization at depth. A surface zinc anomaly with a strong
associated copper anomaly with values up to 1770 ppm Cu, was invest
igated and values up to 5900 ppm Cu and Zn returned from basal till
samples. The anomaly was extended further to the north-east to line
84E where a 520 and 250 ppm Cu are present in basal till samples.
(Maps 5, 6 61 7). Silver values are associated with some of the
higher Cu values.

Geochemical Analyses
Geochemical analyses of some of the samples were carried
out by X-Ray Assay Laboratories Ltd., Toronto, while the balance
were analysed by O'Neill-McHugh Laboratories Ltd. in Ireland. The
samples from the area where gold values were expected were analysed
by X-Ray Lab using the Direct Current Plasma (DCP) technique and
gave a much lower detection limit. The balance of the samples were analysed by AA techniques with Au determined after ignition and
MIBK extraction. The detection limit for Au here is 5 ppb, where
sufficient sample is available. Insufficient sample in some instances
caused high detection limits of 50 ppb but overall results are accept
able in that spotty anomalies occur. Comparison of the two labs
was carried out by running a common batch of samples and results
were found to be acceptable.
4. GEOPHYSICS
Additional E.M. and magnetometer surveys were carried out
during 1982 to complete the survey partially completed in 1981.
Additional detail was carried out. A report on this work together
with maps by Consultant John Betz Ltd. is attached, (Appendix I)
while composite maps presenting the combined results from the con
solidation of both surveys are also included (Maps 8 k 9).
5. GEOLOGY
Geological mapping was completed using the grid for
control and Map 10 and Appendix 2 present the results of this
survey.

INTRODUCTION
As stated in ray report of October 1981, the objective of the
electromagnetic and magnetic surveys on this property was to
detect and outline all conductive and magnetic bedrock zones with
a view to ultimately finding economic mineralization (gold, in
particular) associated with these zones. The electromagnetic and
magnetic coverage of 1982 was intended to plug up 'holes' left
in the coverage of 1981, due to 'bad 1 ice on parts of the lake.
At the same time, some fill-in lines were put in and run, based
on the interpretation of the 1981 results.
The MaxMin II EM (electromagnetic) system was used on this
project. This system d s manufactured by Apex Parametrics Ltd of
Stouffville, Ontario. The methods of operating this system are
amply described in the operations manual and they will not be
repeated here. However, a copy of the specification sheet and a
picture of the system in operation are included at the end of
this report.
For this project, the MaxMin II was used in the maximum coupled
coplanar mode with the turns of the transmitting and receiving
coils held essentially parallel to the surface of the ground.
When working in flat terrain, this mode of operation is the well-
known horizontal-loop mode. The general survey specifications
were: a 200 ft coil spacing and a 50 ft station spacing at fre
quencies of 222, 3555 and sometimes 888 Hz. This was supplemented
by a 100 ft coil spacing and a 25 ft station spacing in one small
part of the grid specifically on Lines 64E, 66E, 68E 6* 7 O K. The
line spacing remained generally at 400 ft, with a few intermediate
lines being added as shown on the accompanying plan.
The magnetometer equipment used in this project was: the G-816
proton precession, as a field unit; and the GSM-8 oroton presession
and C.M.G. MR-10 recorder as a base station unit. The G-816, GSM-8
and C.M.G. MR-10 are manufactured by EG&G Canada, Exploranium
Geometrics Division, Downsview, Ontario; G FM Systems, Inc., Don
Mills, Ontario; and Canadian Mining Geophysics, Ottawa, Ontario,
respectively. The specifications for, and methods of operating,
these systems are amply described in the operations manuals. They
will not be repeated here.

The EM and magnetic field work and the plotting of the results
were carried out by geophysical contractor, Mr. W. Barclay of
Toronto, Ontario. The contouring of the magnetic results was also
done by Mr. W. Barclay. The interpretation of all the results
was carried out by geophysical consultant, John E. Betz, the
author of this report.
The claim numbers covered by the 1982 project are shown on the
two plans included with this report.
PRESENTATION OF THE RESULTS S INTERPRETATION
The conductor interpretation, based on the MaxMin I I results
is shown on Plan l in the pocket at the end of the report. The
magnetic contour picture is on Plan 2. Both plans are at a scale
of l : 4800.
Both the MaxMin II and G-816 results have been plotted in pro
file form. Although these profiles were used in the interpretation,
they are not included in this report. They are in the possession
of Bluestack Resources Limited in Toronto.
NF THE NTERP RTATION
This report was composed specifically to meet the 1982 assessment
requirements, and it deals only with the results pertinent to
this purpose. For this reason, the maps accompanying this report
contain only the conductor interpretation, and the iso-magnetic
contour patterns, in the regions surveyed during this past winter.
However, at this writing separate comprehensive maps of the 1982
and 1981 interpretations are being prepared.
The reader is referred to my report of October 1981, for a
basic discussion of the conductive and magnetic zones on this grid.
The results of 1982 have merely refined the conductive and magnetic
pictures of 1981, by filling in the gaps and improving the reso
lution of closely-spaced parallel conductors. But, the main message
of 1981 remains the same. The present report will deal only with
poi:,ls not macle in last year's report.
An attempt, has been made on Plan l, accompanying this report,
to retain the letter designation, started in 1981, for the various
conductive zones on the grid. Alas, the improved resolution and
fill-in coverage of the 1982 MaxMin survey have resulted in the
-3-
appearance of new conductive zones, between zones which had already
been given a letter designation in alphabetical order.
As described in ray 1981 report, upper case letters were assigned
to each conductor, and a numerical subscript was given to each
letter following a break, or gap, along the length of the conductor.
With the appearance of 'new' conductors between the 'old', it was
necessary to re-use some of the earlier upper case letters, sub
scripting them with lower case letters to distinguish between 'old'
and 'new 1 . The latter point can be best appreciated by superim
posing Plan #1 of this report on Plan l of my 1981 report. In any
event, one of the two comprehensive plans being prepared will
unify the conductive pictures of the 1981 and 1982 reports.
It is not surprising to see a somewhat modified conductor picture
on the western half of the grid, because of the greater resolving
power and gap-filling nature of the '82 MaxMin coverage in this
very complex situation. The situation is less complex on the
eastern half of the grid; so, good correspondence between the "81
and '82 conductors is to be expected. However, the '82 version
of conductors N ? and P is about 100 ft further south than the '81
version on Lines 140F, and l 44E--suggestive of a discrepency in the
chaining results between the two field seasons.
Another possible discrepency exists between the chaining results
of '81 and '82. This is on Lines 112E, 116E and 120E in the region
of 8+OOS to 12+OOS. In '81, a conductor, designated 'D', was in
terpreted on Line 120E between 11+OOS S, 1 2 + OOS, and on Line 112E
between 8+OOS and 9+OOS. This conductor was presumed to cross
Line 116E around 10+OOS, although there was no data on this line.
Alas, the MaxMin results of "82 show a conductor between 7+50S
and 8-fOOS on Line 116E, giving an unlikely northward kink in
conductor D. The alternative interpretation is conductor EI,
shown on Plan l of this report. However, conductor Ei could be the
artefact of a chai.ning error on Line 116E.
Also of note in the '82 MaxMin results are:
a) An unusual-looking MaxMin profile exists south of conductor J j
on Line 112E. There is a hint of a flat-lying conductor or a con
ductor running sub-parallel to the line in this area, and more
data would be required to clarify this matter.
b) There is evidence of a fault between Lines 40E and 44E as sug
gested by the interpreted small offset between conductors H s Ha
and J S Ji. Again a possible 'offset 1 in the chaining results on
these two lines must also be considered, and more data would be
required to clarify this matter.
A few final words on the complex conductor picture on the west
half of the grid; In places, the conductors are too-closely-spaced
for complete resolution by a coil spacing as small as 200 ft. There
are quite possibly more conductive bands than shown on Plan 1.
This matter could be resolved still further with a 100 ft coil
spacing. But a few long drill holes would do a better job of
resolving the picture, yielding much geological information as
we 1 1 .
CONCLUDING Rl'MARK?
Although there is a place for more detailing work, as described
toward the end of the preceding section, there exists in the
present interpretation a wealth of information to follow through
on. When the comprehensive plans of the '81 k '82 conductor and
magnetic contour pictures are completed, there will be a large
basis for geological pursuit.
Unfortunately, there is no simple correlation that I know of
between conductive zones, magnetic zones and gold occurrences.
Nonetheless, the obvious starting point for utilizing the inter
pretation of this and my '81 report is to relate it to all of the
geological and geochemical information known to date. This exer
cise is left to the personnel of Bluestack Resources Ltd.
Neither I, nor John Betz Limited, have any financial interest
in any of the properties of Bluestack Resources Ltd. or any of
its joint venture partners.
I hold B. A. (1952) and M. A. (1953) degrees in geophysics from
the University of Toronto.
I have worked full-time in mining exploration geophysics since
1953, and two sunnier seasons prior to 1953.
All statements made in this report are correct to the best of
my knowledge.

GEOLOGICAL MAPPING SLATE BAY AREA
RED LAKE MINING DIVISION
SUMMER - FALL 1982
O.M.E.P. Application No. OM 82-1-C-l
INTRODUCTION
The area mapped is located towards the eastern end of the
Red Lake greenstone belt approximately 7 air miles NNW of the town
of Red Lake. Access may be gained most conveniently by boat in
summer and snowmobile in winter. The 10 mile lake journey takes
approximately 20 minutes.
EXPLORATION HISTORY
The earliest work recorded in the Red Lake area was at
Slate Bay in 1897. The North West Ontario Exploration Company sank
a small shaft about 1/3 mile north of the present Luxor claims. The
results were unsatisfactory and the project was abandoned.
The earliest recorded work on the claim area occurred in
1933. A number of trenches were opened on Luxor claims KRL 2206 and
2208. Erratic gold values were encountered in association with
quartz veins and quartz porphyry intrusives. Further work was carried
out and two areas were diamond core drilled in 1937. One "zone" on
KRL 2206 and 2208 was found to contain low gold values. The other
"zone" on KRL 2214 carried potentially significant gold values. The
best intersection was check assayed at 0.6 oz/ton Au over 5 ft. in
a 15 ft. thick unit averaging 0.23. This promising intersection was
not followed up and the project was terminated.
The next phase of exploration took place in 1947 when more
diamond drilling was carried out. The work was centred on the KRL
2214 gold zone. Low values in gold were encountered but the promising
intersection from the 1937 drilling was not followed up. It is not
W-rf J S -S-
- 2 -
clear from the notes as to why this happened. However since the
thinking of the day assumed quartz porphyry dykes as the host rock
to gold mineralization the potential significance of 0.23 oz/ton over 15 ft. in tuff may have been overlooked.
Further diamond core drilling took place in 1962, 1965 and
1966. The 1962 drilling intersected interesting Ag values. The
best assay recorded ran 4 oz/ton Ag over 5.5 ft. Drilling in 1965
and 1966 was done to test various E.M. anomalies on the block.
Interesting minor mineralization was found.
GEOLOGICAL MAPPING
1. Method
The geological mapping program commenced in July 1982 and
was terminated in October 1982. Using the existing grid and air
photographs for reference the area was mapped on a scale 1:4800. The
grid was also auger/grub hoe sampled at 50 ft. intervals in the "B"
soil horizon. Traverses between the cut lines were also used but
the scrub bush covering much of the property made this unworkable for
most of the area. Features of geomorphological interest were also
noted during the mapping.
2. Lithologies
The area may be sub-divided into three main "field" form
ations. It will be appreciated at this stage that the terms and
sub-division employed are subject to change and refinement as detailed
knowledge of the area increases.
l! -l l!FORMATION "1
This formation comprises the NW part of the claim block
and covers both the silver and gold bearing zones referred to above.
- 3 -
The succession is a series of intermediate basalts and tuffs. The
units represented appear as relatively massive flows (?) in the
extreme north-west with a transition into waterlain tuffs towards
the south-east. In common with the rest of the area metamorphic
alteration appears to just enter the lower greenschist facies and
many macrofeatures remain recognisable. Differentiation between
fine grained clastic metasediments and tuffs can be difficult in
this area therefore the geological contact should be interpreted
loosely.
Minor (?) granodioritic and quartz feldspar porphyry
intrusives occur at a number of locations in the formation. Rhyolitic units concordant (?) with the strike of the country rock occur in
frequently but appear to be relatively substantial in extent. Blebs
and stringers of carbonate were noted in a number of exposures in
the tuff/basalt lithologies.
An extensive magnetite formation occurs on KRL 2206 and
2208. This was trenched by Bluestack Resources Ltd. personnel in
1981 and indicated the magnetite stratigraphically overlying a garnetiferous, epoditic chloritic alteration "zone". The presence
of angular to sub-angular block of magnetite incorporated in the
alteration zone strongly suggests the presence of a breccia pipe.
A chert formation overlies the magnetite.
The trenching program indicated interesting silver (5 oz/ton
over 5 f t.) and copper values (170 over 5 ft) in the zone. The local
enrichment of carbonate noted in one trench loosely correlates with gold values of up to 0.09 oz/ton (See trenching report 1981).
The area is structurally complex with a number of small
Light folds and a dominant cleavage/shearing direction of approx
imately 060 0 . The minor folds give conflicting evidence but a general
anticlinal regard to the south-east was noted. Dips on bedding
planes tend to be 70 0 to 80 0 N.W. or S.E. Detailed structural
- 4 -
interpretation will require a considerable amount of stripping and
cleaning of exposure.
FORMATION "2"
This formation comprises the centre of the mapped area. It is characterized by a thick succession of polymictic conglomerates.,
sandstones, shales and minor arkosic and calcareous sediments. The
formation is wedge shaped with the apex pointing towards the NE.
Exposure is good over the hilly conglomeratic units but over much of
the area a varved clay/sand overburden cover makes interpretation
of geologic contacts very speculative. The occurrence of a marble
unit at the N.E. end of this area appears to indicate a facies change from S to N. Cherty iron formation and graphitic shales develop to
the S.E. of ths formation. Minor chalcopyrite and pyrrhotite occur
in the graphitic shales noted on KRL 526078. The contact with
Formation "3" is not clear since a large quartz feldspar porphyry
and a basic gabbroic intrusive has caused complex structural and
stratigraphic changes.
HO IIFORMATION "3
This formation of intermediate/mafic volcanics is poorly
exposed on the south eastern "edge" of the mapped area. The develop ment of pillow and possible pahoehoe textures in intermediate volcan
ics suggests a marginal sub-aerial-submarine environment. A conglom
eratic iron rich unit is found on a submerged reef on KRL 526089
