Gentlemen:
The following report describes the results of a
ground scintillator survey conducted over a group of your
claims located in Burleigh and Anstruther Townships, Ontario
and referred to as the western extension of the "D" zone
airborne scintillometer anomaly.
The work was conducted by Geo-Technical Development
Company Limited during the period from September 15th to 23rd,
19J?H. and the results are shown on Plan No. l accompanying
this report, plotted to a scale of one inch equals 200 feet*
Summary and Conclusions
The ground scintillator survey has located anomalous
points where the radiation is not more than 1| times higher
than background* Groups of these slightly higher radioactive
points correspond approximately to the two anomalous zones
outlined by an airborne scintillometer survey. Similar points
are located out of these zones.
It appears that the anomalies outlined by the air
borne radiation survey were the result of the slightly
radioactive pegmatite and pegmatitic granite plus the effect
of mass. However, the line grid spaced at 800 foot intervals
does not give sufficient information to justify the value of
seven claims located at the centre and south parts of the
surveyed area.

Property, Location and Access
The claims covered by the ground scintillator survey
over the area referred to as the west extension of the "D"
zone are located in Lots 21 to 26, Concessions VIII, IX, and X,
Burleigh Township, Peterborough County, Ontario. Claims are
numbered as follows:
E.O. 9039, 90l|.0, 9173, 9182, 9183, 9195, 9198, 9199, 9200, 9201, 9206, 9207, 9208, 9209 and 9211.
The north unsurveyed part of claim 9173 extends into Anstruther
Township.
The claims group is bounded by the property of Pol*
Star Mines to the east, Crab Lake and its connecting swamps to
the north, and is open to the west.
Crab Lake is located west about 2^ miles from the
town of Apsley. Prom Apsley, along Highway No. 28 to the
south about l mile, there is a farm road going west. This
farm road has a length of about 1/3 of a mile and is connected
to a wagon road at its west end. This wagon road leads to
Crab Lake. Line lOi^W of the property has been cut to the
south shore of Crab Lake from the base line which is the
extension of the "D" base line of Pole Star Mines to the east.
The intersection of these two lines is located about 2 miles
from the east end of the lake, near the west end of the lake.
Due to the fact that there is a creek running south from the
southeast corner of Crab Lake, the above-mentioned inter
section is best reached by motor boat or canoe along Crab
Lake.

Topography
The high hills in this area are about 100 to 11|0
feet above the water level of Crab Lake which has an elevation
of 1070 feet. The south shore of Crab Lake is bordered by
cliffs of from 1+0 to 70 feet high above the lake. The highest
hills are located along a more-or-less east-west centre line,
through the claims. Elevations to the south are lower than
to the north. However, due to the many wet valleys, swamps
and beaver ponds, the south and southwest parts of the map
area are rough for making traverses.
The overburden in the whole area is very thin.
Forest growth is also thin except occasionally in the lower
ground and slopes with thicker soil* The forest growth
consists mainly of second-growth hardwood, maple, birch and
oak on the higher ground; and poplar, ash and alders growing
in the low and swampy areas.
Geology
According to geological Map No, 52-a, accompanying
a report by J. Satterly, Ontario Department of Mines, f?2nd
Annual Report, Vol. Lil, Part II, 19lj3, the claims group is
located within a granitic complex with granite, granite gneiss
and pegmatite; hyftbrid gneisses of igneous and sedimentary
origin. No detailed geological map and structural data of
the area havebeen published.
Detailed geological mapping has been carried out
by Geo-Technical Development Company Limited over this area
GEO -TECHNICAL DEVELOPMENT COMPANY L IMITED
during the field season 19514-* A separate report with an
accompanying geological map has been submitted.
The detailed geological mapping classified the rook
types found in this claims group into the following: pegmatite,
pegmatite complex, granite and pegmatitic granite, granite
gneiss, biotite gneiss, hornblende gneiss and amphibolite*
The rock types are described in the above-mentioned geological
report*
A network of topographic lineations and the general
trend of gneissosities in the area indicate that the claims
group is located on a slightly disturbed large fold, open to
the southwest. Three minor faults have been located, several
geological discontinuities suggested.
Interpretation of Ground Scintillator Survey
An airborne scintillometer survey has outlined two
anomalous zones near the centre of this group of claims.
The ground scintillator survey located points where the
radiation is higher than background but not more than four
times higher. Groups of these slightly higher radioactive
points correspond approximately to the two anomalous zones
outlined by the airborne radiation survey. However, similar
points have been located out of these zones.
Geological mapping and spot checks revealed that
all the higher points located by ground scintillator surveying
are underlain by pegmatite or pegmatitic granite. Furthermore,
the concentration of radioactive elements in these rocks are
BED - TECHNICAL D E V E L DPMENT COMPANY L IMITED
-5-
seemingly less than those found in the same rock types which
occur in the adjoining mine properties. However, as also
pointed out in the geological report, work carried out along
the line grid spaced at 800 foot intervals does not give
sufficient data for a definite conclusion concerning seven
of the claims located near the centre and south parts of
this claims group.
Instrument Data
The instrument used for recording radioactivity
was a "Portable Scintillator Counter", Model III with ranges
of .025* .05* .25* *5* 2.5 and 5*0 milliroentgens per hour*
The instrument has an accuracy of 5^ of three-quarters full
scale. Standard procedure was to calibrate the instrument
with a standard radioactive chip of 0.19 milliroentgens per
hour. Check readings were made several times each day to
determine possible changes in the instrument during the
traverse run. This check also served to establish a back
ground count for the area being surveyed.
Survey Data
A ground scintillator survey was conducted over your
claims group located in Burleigh Township, Peterborough County,
Ontario and referred to as the western extension of the "D"
zone.
The survey was carried out by Geo-Technical
Development Company Limited during the period from September
15th to 23rd, 19514- and the results are shown on Plan No. l
accompanying this report.

A base line with a bearing of N i^.20E was extended
west from the adjoining property of Pole Star Mines Limited
across the claims group, cutting the south part of two
radioactive anomalies as inferred from airborne scintillometer
survey data. Picket lines at 800 foot intervals were cut at
right angles to this base line, extending one-quarter mile
north and south and line lOljW which extends about ij.000 feet
to the south shore of Crab Lake, Scintillator readings were
taken at 50 foot intervals along the picket lines and base
line. The readings are expressed in milliroentgens per
hour and are plotted on the accompanying plan, contours being
made on the basis of even multiples of readings obtained.
A total of 7*26 miles of line was covered by the
ground scintillator survey, requiring 76? station readings.
The total number of eight-hour man-days required
to complete this work is as follows:

Gentlemen:
The following report describes the results of a
geological survey conducted over your group of claims
located in Burleigh Township, Peterborough County, Ontario
and referred to as the western extension of the "D" zone
airborne scintillometer anomaly.
The work was carried out by Geo-Technioal Develop
ment Company Limited during the period from August 22nd to
September 23rd, 195^ and the results are shown on Plan No. l
accompanying this report, plotted to a scale of one inch
equals 200 feet.
Summary and Recommendations
The rocks of the claims group are classified into
the following types: pegmatite, pegmatite complex, granite
and pegmatitic granite, granite gneiss, biotite gneiss,
hornblende gneiss and amphibolite.
The claims group is located on a large, slightly
disturbed fold, open to the southwest* Three minor faults
have been located and several geological discontinuities
suggested.
No favourable concentration of uranium has been
discovered. It is suggested that further geological and
magnetometer surveying be carried out over claims E.0. 9039,
90ij.O, 9200, 9201, 9209, 9210 and 9212.

Property, Location and Access
The claims covered by the geological mapping over
the area referred to as the west extension of the "D" zone
are located in Lots 21 to 26, Concessions VIII, IX and X,
Burleigh Township, Peterborough County, Ontario. Claims
surveyed are numbered as follows:
E.G. 9037, 9038, 9039, 90i 9, 9172, 9173, 917l|.,9181, 9182, 9183, 9195, 9198, 9199, 9200,9201, 9206, 9207, 9208, 9209, 9211, 9212.
The north part of claims 9173 and 917lj- extend into Anstruther
Township.
The claims group is bounded by the property of
Pole Star Mines to the east, Crab Lake and its connecting
swamps to the north and is open to the west.
Crab Lake is located west about 2^ miles from the
town of Apsley. Prom Apsley along Highway No. 28 to the
south about l mile there is a farm road going west. This
farm road has a length of about 1/3 of a mile and is con
nected to a wagon road at its west end. This wagon road
leads to Crab Lake. Line lOli-W of the claims group has been
cut up to the south shore of Crab Lake from the base line
which is the extension of the "D" base line of Pole Star
Mines to the east. The intersection of these two lines is
located about 2 miles from the east end of the lake, near
the west end of the lake* Due to the fact that there is a
creek running south from the southeast corner of Crab Lake,
the above-mentioned intersection is best reached by motor
boat or canoe along Crab Lake.

Topography
The high hills in this area are about 100 to llj.0
feet above the water level of Crab Lake which has an elevation
of 1070 feet. The south shore of Crab Lake is bordered by
cliffs of from lj.0 to 70 feet above the lake* The highest
hills are located along a more-or-less east-west centre
line through the claims. Elevations to the south are lower
than that to the north. However, due to the many wet
valleys, swamps and beaver ponds, the south and southwest
parts of the map area are rough for making traverses*
The mantle of glacial drift is very thin in the
entire area. Forest growth is also thin, except:!occasionally
in the low ground and on slopes with thicker soil. The forest
growth consists mainly of second-growth hardwood, maple, birch
and oak on the higher ground; and poplar, ash and alders
growing in the low and swampy areas.
General Geology
The northern part of Burleigh Township is underlain
entirely by rocks of Pre-Cambrian age. According to a
geological map published by the Ontario Department of Mines,
Map No. 52-a, accompanying a report by J, Satterly, Ontario
Department of Mines ^2nd Annual Report, Vol. Lil, .Part II,
I9k3t tha claims here concerned should be located within a
granitic complex with granite, granite gneiss, pegmatite;
hybrid gneisses of igneous and sedimentary origin.
i E O - TECHNICAL DEVELOPMENT COMPANY LIMITED
"k-
Aerial photographs of the area show that there are
well-defined topographic lineations in the area* Geological
traverses made by the writer reveal that a network of topo
graphic lineations trend approximately parallel to the
gneissosity or banding of the underlying rock. Because of
this and the study of lineations shown on aerial photographs*
one can suggest that the claims are located on a large,
slightly disturbed fold.
Rock types
The rocks of the claims group are classified into
the following types: Pegmatite, pegmatite complex, granite
and pegmatitic granite, granite gneiss, biotite gneiss,
hornblende gneiss and amphibolite.
The following are descriptions of the rock types
in this area. It should be noted here that all these names
are field terms and no thin section work has been carried
out.
1. Pegmatite; The pegmatite found in the area is
granite pegmatite. Its feldspar ranges from pink to white,
generally light-pinkish. Quartz is, as a rule, colourless*
Graphic intergrowth of feldspar and quartz has been observed
in large pegmatite outcrops of this area. Biotite is, as a
rule, very small in size. Small disseminated crystal* of
magnetite have been observed in a small pegmatite dyke
cutting granite.
BED -TECHNICAL DEVELOPMENT COMPANY L IMITED
-S-
2. Pegmatite Complex; This term refers to inter
mingling of pegmatite granite and granite gneiss* rarely also
pegmatite and hornblende or biotite gneisses in which the
pegmatite is predominant (over J?0^). Only much more detailed
mapping may permit the separation of some of these units from
the complex. In most cases this complex consists of typical
lit-par-lit injections of pegmatite in an amount of over 50^*
3. Granite and Pegmatitic Granitet Oranite and
pegmatitic granite found in this area is generally slightly
pinkish in colour* The texture of the granite ranges from
fine to coarse-granular, sometimes pegmatitic. In many cases
the pegmatitic granite grades into pegmatite. On the other
hand, it was dependent entirely on field observation of
gneissosity to name an outcrop as granite or granite gneiss.
Further investigations may show that some of the outcrops of
granite are actually granite gneiss. It is not uncommonly
found that a granite body contains a certain amount of
pegmatitic veinlets or small dykes,
I|. Granite Gneiss: The granite gneiss is a banded,
fine to medium-grained granitic rock and ranges from light
pink to rarely, light grey in colour. This granite gneiss
is occasionally found lit-par-lit with, or cut by, pegmatite.
The pegmatite in this case may run as high as ^0^ and yet the
outcrop is coloured as granite gneiss in the geological map
accompanying this report.
GEO -TECHNICAL DEVELOPMENT COMPANY LIMITED

5. Biotite Gneiss: The biotite gneiss is grey to
dark grey in colour, generally fine to medium-grained* The
rock is composed of biotite, feldspar and quartz and
occasionally a small amount of hornblende. Pegmatitic and
quartz veinlets have been found cutting outcrops of biotite
gneiss in claim E.O. 9209*
6. Hornblende Gneiss and Amphibolite: Similar to
the biotite gneiss, the hornblende gneiss found in this area
is grey to dark grey in colour* A grey variety located
along Line 112W, 220 feet north, 60 feet east, is silicified
to a certain degree* Another variety located along the same
line, i|.70 to 590 feet south, is in part composed nearly
entirely of iron-rich hornblende, which should be classified
as amphibolite.
Structural Features
The pegmatite bodies found in the west part of the
property are, as a rule, lit-par-lit to their country rocks.
This is demonstrated by the appended section along Line 167-38W
from 130 to 300 feet south. The pegmatite bodies to the east
of the area are smaller and in places cut across the gneiss
osity of their country rocks. The pegmatite bodies found to
the south in claims 9212, 9209 and 9201 are, as a rule, in
contact with biotite gneiss and hornblende gneiss - indications
of contact metamorphism.
BED -TECHNICAL DEVELOPMENT COMPANY LIMITED

Geological mapping has located three small faults
in the area as plotted on the accompanying map* One of
these faults is also shown on Figure No. l appended hereto*
None of the faults suggest any major displacement. However,
aerial photographs of the area show that there are well-defined
topographic lineations in the area. Geological traverses made
by the writer revealed that a network of topographic lineations
trend approximately parallel to the gneissosity or banding of
the underlying rock. This network of lineations and the
general trend of the gneissosity of granite gneiss in the
area indicate that the claims group is located on a large
fold, open to the southwest. There is a series of topographic
lineations cutting this fold. These lineations are fractures
or faults. All lineations showing in the aerial photographs,
where incompetent rock types and/or local variations of
strikes have been located by geological mapping, are plotted
on the accompanying map as possible faults for the interest
of further investigation.
Economic Geology
Two radioactive anomalies have been Inferred from
airborne scintillometer survey data covering this area* These
two anomalies are located approximately one mile from Crab
Lake, near the centre of this group of claims. The ground
scintillator survey located points which give slightly higher
readings but none of these readings are over Ij. times back
ground.
GEO -TECHNICAL DEVELOPMENT C OMPANY LIMITED
-8-
Spot checks carried out at the same time when the
writer was doing geological mapping indicate that all the
points where higher readings were obtained by the ground
scintillator survey are underlain by pegmatite or pegmatitic
granite. The concentration of radioactive elements in these
rocks is seemingly less than that found in the same rock
types occurring in the adjoining properties* However, the
picket lines checked are at 800 foot intervals and there are
several geological discontinuities more-or-less parallel to
them. The writer does not feel that sufficient information
is available to justify the expression of a definite con
clusion on this property.
Furthermore, the discovery of uranium ore associated
with magnetite in the Faraday Mines property has demonstrated
the probability of the association of radioactive anomalies
to magnetic anomalies as an indication of an ore body.
An aeromagnetic survey of the Geological Survey of Canada
has discovered a relatively high anomaly (3300 gammas) at
a locality about l to 1^ miles south of Crab Lake (Geological
Survey of Canada, Map 103G). The writer is not sure of the
proximity of this aeromagnetic anomaly to the anomalies out
lined by an airborne scintillometer survey but they are close
enough to be of interest,
It is suggested that further geological and
magnetometer work be carried out over claims E.O. 9039,
90i|.0, 9200, 9201, 9209, 9210 and 9212,
BED -TECHNICAL DEVELOPMENT COMPANY LIMITED

Picket lines with 200 foot intervals should be cut between
Lines 96 to 130W, vertical to the base line. These linea
should be extended ll|00 feet to the north and south to the
boundary. Magnetometer surveying and geological mapping
along with scintillator spot checks should be carried out
along these lines.
Survey JData
A geological survey was conducted over your claims
located in Burleigh Township, Peterborough County, Ontario
and referred to as the western extension of the "D" zone
airborne scintillometer anomaly.
The work was carried out by the writer on behalf
of Geo-Technical Development Company Limited during the
period from August 22nd to September 23rd, 19f?l| and the
results are shown on Plan No. l accompanying this report
plotted to a scale of 6ne inch equals 200 feet.
A line grid established for a ground scintillator
survey was used for the geological traverses. A base line
with a bearing of N ij.2 E was'extended west from the adjoining
property of Pole Star Mines Limited across the claims group
cutting the south part of two radioactive anomalies as
inferred from the airborne scintillometer survey data.
Picket lines at 800 foot intervals were cut at right angles
to this base line extending one-quarter mile north and south
and Line 10lj.W which extends about ijOOO feet to the south
shore of Crab Lake.
