SUMMARY
The 'U' Island property of Phoenix Gold Mines Limited
comprises 22 leased and patented mining claims located in the
southwest corner of McGarry Township in northeastern Ontario.
The property lies less than l mile south of the Larder Lake -
Cadillac Fault Zone, a major linear structural' feature to which
many past and present gold producers in northeastern Ontario and
northwestern Quebec are spatially related. The Kerr-Addison mine
is located 2 miles (3.2 km) northeast of the property.
During the period of January 21 to February 14, 1987,
Phoenix performed linecutting, geophysical surveys and lake
bottom depth sounding on the 'U' Island property. The purpose of
the program was to attempt to detect geophysical responses from
the sedimentary and komatiitic Archean rocks of the Larder Lake
Group which underlie the lake's northeast arm. Mineralization
at the Kerr-Addison mine occurs within the sedimentary rich
portion of the Larder Lake Group.
As was expected, the combined obstacles of water depth,
overburden thickness and the wedge of Cobalt cover rocks obscured
our geophysical examination of the Larder Lake Group over most of
our grid. However the geophysical response on the north shore of
the channel provides us with a narrow "window" through which we
can glean some knowledge of the nature of the rocks of the Larder
Lake Group on our property.
The potential exists for "Kerr" type stratiform gold
mineralization on the 'U 1 Island property. In this regard a
preliminary program of diamond drilling at an expected cost of
$215,165 is herein outlined.
-2-
INTRODUCTION
The Phoenix land holdings in the Larder Lake area consist
of two properties which straddle the Larker Lake Break to the
west of the Kerr Addison mine in Virginiatown.
The Winchester property consists of 15 patented mining
claims and 2 unpatented mining claims located on either side of
the McVittie-McGarry Township line, just north of Highway #66.
The 'U' Island property consists of 22 leased and patented
mining claims located in the southwest corner of McGarry
Township, on the northeast arm of Larder Lake.
Prospecting and diamond drilling were carried out on both
properties during the mid-30's and 40's.
Our 1987 program began with 16.4 miles of linecutting on the
Winchester property and 12 miles of temporary picket line on the
'U 1 Island property. High resolution magnetometer and VLF-EM
surveys were performed on both properties. As expected, the
combined obstacles of water depth and lake bottom sediments
obscured most of the geophysical response of the Archean rocks
on the 'U 1 Island property.
A full program of surface exploration is planned for both
properties in 1987. Follow-up on geophysical anomalies,
prospecting, soil sampling, rehabilitation of old showings and
geological mapping will be carried out on the Winchester
property. Diamond drilling will be carried out on the 'U 1 Island
property and, depending on the results of the aforementioned
surface program, the Winchester property.

LOCATION AND ACCESS
The property is located on the northeast arm of Larder Lake,
2 miles (3.2 km) southwest of Virginiatown. During the winter,
the Kerr-Addison tailings dam on the north shore of Larder Lake,
1/2 mile (0.8 km) west of the property provides a convenient
take-off point for snowshoe access. The dam can be reached by
a private road which leaves Highway #66 from a point 1.6 miles
(2.6 km) west of Virginiatown. Snowmobiles or boats can be
launched from the Virginiatown pumphouse, about l mile (1.6 km)
northeast of the property.

LOCAL RESOURCES
A. Water
Larder Lake could sustain a mining and milling operation of
considerable size.
B. Power
Ontario Hydro's power line parallels Highway #66, 3/4 of a
mile (1.2 km) north of the property.
C. Transportation
The property is located 3/4 of a mile (1.2 km) south of
Highway #66 and 2.5 miles (4 km) south of the Ontario
Northland Railway track. Daily air service is available from
the town of Kirkland Lake, about 25 miles (40 km) to the
west.
D. Infrastructure and Human Resources
The Kerr-Addison mine, located in Virginiatown, could provide
milling services for a developing mine. The long history of
mining as well as the presence of producing gold mines in the
area insures an experience work force.
-6-
HISTORY
The Cobalt silver rush of 1903 encouraged prospecting which
extended further afield. After examining the area in 1904, H.L.
Kerr decided that further investigation was warranted. Upon
this recommendation Dr. W. Addison visited the Larder Lake area
in 1906. He met a Dr. R. Reddick of Ottawa who was also
interested in the area. Reddick and Addison staked 7 and 3
claims respectively which would become the Kerr-Addison mine 32
years later.
In August, 1906, Reddick discovered a gold showing which
sparked the first gold rush in northeastern Ontario. Development
work on this showing in 1907 failed to uncover any economic gold
mineralization. This proved to be a serious setback for the
Larder Lake gold camp for many years.
Most of this early work was concentrated on stockworks of
gold bearing quartz veins and stringers in a rusty weathering
carbonate rock which was locally called 'dolomite*. This is the
Kerr-Addison "carbonate ore 1 , which has erratic gold values often
restricted to areas of visible gold in the quartz veins.
In 1908, S314 (15.2 oz. @ S20.677oz.) of gold was recovered
from approximately 100 tons of ore from the Reddick property.
This gold was used in the first gold coins to be minted in
Canada.
In 1914, Associated Goldfields Ltd. purchased the Reddick
claims (L1749, L1751, L1814, L1839, L1840, L1904 and L1905) and
the Kerr-Addison claims {L1848, L1849 and L1850). After
considerable surface diamond drilling, a shaft was sunk and
lateral work was done on each of the claim groups with
disappointing results. It would be noted that the north
cross-cut on the 300 foot level on the Reddick property missed
what would become the Kerr-Addison No. 10 orebody by 20 feet.

PREVIOUS WORK
The 'U' Island property has been drilled by two different
companies.
The Knutson Mining Corp. Ltd. drilled 3 holes (one of which
washed out after 116') totalling 1,127' during the period March
19 - April 22, 1937. The holes were drilled from the ice on
Larder Lake on claims L33272 and L33802. Core recoveries were
poor and sludges were lost after 101' of hole #1 (total 609') and
80' of hole #3 (total 402'). No significant gold mineralization
was encountered.
A more extensive drilling program was carried out by Larder
"U" Island Mines Ltd. during the beginning of 1945. At least 32
holes were drilled on the 'U 1 Island property and on the
adjoining Wesley Gold Mines Limited claims to the west. Most of
the drilling was concentrated on the northwest corner of claim
L41115. Erratic gold mineralization was encountered over narrow
widths.
-10-
REGIONAL GEOLOGY
The 'U 1 Island property is located in the southwestern
portion of the Archean Abitibi Subprovince of the Superior
Structural Province (Fig. 2). The volcanic and sedimentary
rocks of the Tiramins-Kirkland Lake-Larder Lake-Noranda area form
a large east trending synclinorium which plunges to the east.
The Destor-Porcupine Fault Zone and the Kirkland Lake-Larder
LakeCadillac Fault Zone transect the northern and southern limbs
of the synclinorium, respectively. Small plutons of
granodioritic to syenitic composition intrude the supracrustal
rocks. Archean to Lake Proterozoic diabase dykes occur
throughout the area. Proterozoic sedimentary rocks of the Cobalt
Group onlap the subgreenschist facies Archean rocks from the
south.
The volcanic stratigraphy consists of a Lower and an Upper
Supergroup (Jensen, 1985). ln The Lower Supergroup on the
southern limb of the synclinorium, southeast of Kirkland Lake,
contains a cycle of komatiitic, tholeiitic, and calc-alkalic
volcanic rocks represented by the Wabewawa, Catherine and Skead
Groups respectively."
The property is located within the Upper Supergroup, a
volcanic cycle which consists of "komatiitic lavas of the
Larder Lake Group (Kerr-Addison, McBean, Cheminis, Omega)
succeeded by tholeiitic rocks of the Kinojevis Group and calc-
alkalic rocks of the Blake River Group. Alkalic volcanic rocks
of the Timiskaming Group (Macassa) unconformably overlie the
Blake River and Kinojevis Groups."
The total thickness of the Upper Supergroup is greater than
30 km. l Jensen, L.S. and Langford, F.F.1985: Geology and Petrogenesis of the Archean Abitibi Belt in

PROPERTY GEOLOGY
The area of the 'U 1 Island property has been mapped by P.E.
Hopkins, Ontario Department of Mines 1924 and J.E. Thomson, ODM,
1941.
The property is underlain by komatiitic flows and
sedimentary rocks of the Larder Lake Group. Unconformably
overlying these rocks are the Proterozoic greywackes of the
Cobalt Group of the Huronian Supergroup.

REGIONAL AND LOCAL STRUCTURE
The Larder Lake-Cadillac Fault is the major linear
structural feature in the area. It can be traced from Kenogami
Lake in the west to Val d'Or in the east - a distance of over 90o
miles (150 km). The regional strike of the Fault is 090 ,
dipping steeply south. In Mcvittie and McGarry Townships, the
strike of the fault zone is 060 , w
the north at the Kerr-Addison mine.
strike of the fault zone is 060 O , with an anomalous 70 dip to
The Larder Lake Fault Zone separates the younger Timiskaming
Group to the north from the much older Larder Lake Group to the
south. It also separates two structural domains. North of the
"Break", the down-faulted side, fold axes plunge steeply to the
east. South of the "Break", the up-faulted side, fold axes
plunge moderately to the southwest.
In the property area, the "Break" forms the linear south
shore of Barber Lake and passes between the south end of Bear
Lake and the north shore of Tournene Lake.

PRESENT WORK
The program on the "U 1 Island property comprised
linecutting, lake bottom sounding and geophysical surveys. The
results of the work are shown on the following maps and drawings
found in Appendix l at the rear of this report:

The total magnetic field strength was measured with an EDA
proton precession magnetometer, PPM-350. Secular and diurnal
drift were corrected by an EDA PPM-400 base station magnetometer.
The earth's magnetic field was rated quiet during the survey
period by the Geomagnetic Forecasting Serivce and this was indeed
the case with daily (diurnal) magnetic drifts at the base station
of less than 2 nt (nanotesla).
The VLF-EM survey was performed with a Geonics EM-16 very
low frequency receiver tuned to the Cutler, Maine transmitter
station.
The lake bottom sounding consisted of 153 measurements from
holes spaced from 25' (7.62 m) to 100' (30.48 m) apart on lines
4W, 4E, 12E, 20E, 28E and 36E.

Stations consisting of blazed trees marked with their grid

intersect the lakeshore. These stations will serve as reference

GEOPHYSICAL RESULTS
Introduction
During the period January 21 to February 14, 1987, Phoenix
Gold Mines Limited performed geophysical ground surveys on the
'U' Island peroperty located in the southwestern corner of
McGarry Township, northeastern Ontario.
The program consisted of a VLF-EM survey using a Geonics
EM-16 tuned to Cutler, Maine and a magnetomenter survey carried
out with EDA field and base station proton magnetometers. While
the base station was in operation on 'D 1 Island, a magnetic
"bench mark" was established at the other local Phoenix property,
the Winchester. This "bench mark" was then used to establish a
magnetic field value for the base station location on the
Winchester property. Therefore the magnetic values on one
property may be compared to the other.
The surveys were performed on a winter-cut grid on the
island itself, while on the ice, a temporary grid was established
with transit control. The baseline was oriented at 055 with
crosslines spaced 400' (121.9 m) apart. Pickets were planted
every 100' (30.48 m) while readings were taken at 50' (15.24 m)
and sometimes 25' (7.62 m) intervals.
Magnetometer Survey
The magnetic survey measured the total magnetic field in
nanotesla (nt) or gammas. The magnetic field increased in
strength as the Cobalt cover rocks were approached. Three
variables control the magnetic field strength on Larder Lake -
water depth, the magnetic properties of the underlying bedrock
and the magnetic properties of the lake bottom's sediments.
-16-
The only features of interest are the magnetic high on L36E
350N and the anomalous northward curve of the magnetic contours
centered on L24E.
The magnetic high on L36E (see Profile) represents the
Cobalt cover' rocks. Since the water depth is consistent with
respect to the other sounded lines, the Cobalt rocks are probably
elevated at this location.
This may represent the forward edge of the onlapping Cobalt
cover rocks.
The large magnetic curve on L24E probably represents a
northward embayment of Cobalt rocks onto the Larder Lake Group.
VLF-EM Survey
The VLF-EM survey measured the In-phase dip angle and
quadrature values. It was found that the limit of VLF
penetration on Larder Lake was about 60' (18.3 m). Water depths
greater than this caused In-phase and quadrature readings to
decrease to zero (see Profiles).
However, the VLF data from the north and south shore of the
channel has provided us with a means of determining the
approximate lake bottom profile. On the north shore (see Bottom
Profiles), a quadrature measurement that was less than its
corresponding In-phase reading indicated a steep slope with
relatively little overburden build-up. On the same shore, an
In-phase that was less than its corresponding quadrature
indicated the presence of a shelf with an overlying layer of
overburden.
On the south shore of the channel this empirical
relationship is reversed, ie. relatively negative quadrature -
shelf.
-17-
Th is data should be used to avoid the slope and the bottom
of the slope when attempting to drive drill casing through to
bedrock. One of the Knutson Mining diamond drill holes (#2)
washed out after 116' (35.4 m). It had been collared around
5200E 800N. The VLF-EM data suggests a shelf from L48E to L76E
on the north shore of the channel. The Knutson DDH, spotted
approximately 300' (91 m) from shore would have passed into the
unstable bottom of the slope.
-IB-
CONCLUSION^
1. Due to its structural and stratigraphic setting within the
Larder Lake Group (the same Group as hosts the Kerr-Addison
mine), the 'U' Island property has the potential to host a
stratiform gold deposit.
2. Due to the combined obstacles of water depth, overburden and
Cobalt Group sedimentary cover rock, conventional surface
exploration methods, with the exception of diamond drilling,
are unable to test the gold bearing potential of the 'U'
Island property.
3. Priority must be placed on understanding the stratigraphy of
the Larder Lake Group since the gold mineralization occurs
within interflow sediments to komatiitic flows or
interlayered with coarse turbiditic sedimentary rocks
composed of locally derived volcanic detritus.
-19-
RECOMMENDATIONS
It is recommended that:
1. The Company should file an application for a grant with the
Ontario Mineral Exploration Program (OMEP) of the Ontario
Ministry of Northern Development and Mines.
2. Carry out 5,000' (1,524 m) of diamond drilling between the
northshore of Larder Lake and 'U' Island in order to test for
gold mineralization as well as to gain some insight into the
stratigraphy of the Larder Lake Group underlying the
property. This stage of diamond drilling should be
considered preliminary in the sense that an understanding of
the stratigraphy of the property is essential in locating a
"Kerr" type ore deposit.

SUMMARY
The Winchester property of Phoenix Gold Mines Limited
comprises 15 patented and 2 unpatented mining claims located in
Mcvittie and McGarry Townships in northeastern Ontario. The
property lies just north of the Larder Lake-Cadillac Fault Zone,
a major linear structural feature to which many past and present
gold producers in northeastern Ontario and northwestern Quebec
are spatially related.
During the period of January 21 to February 22, 1987,
Phoenix performed linecutting and geophysical surveys on the
Winchester property and the adjoining water-covered claims. The
purpose of the program was to obtain a preliminary geophysical
examination of the property. Previous work in the 1940's had
revealed gold mineralization in quartz veins and cherty breccia,
hosted by syenitic rocks which intrude Timiskaming sedimentary
rocks; a situation which is similar to the Macassa mine in
Kirkland Lake.
Several prominent geophysical anomalies were identified.
In this regard, a program of prospecting, limited geochemical
sampling, geological mapping, stripping and trenching, and if
warranted, diamond drilling at an expected cost of S352,705 is
herein outlined.

INTRODUCTION
The Phoenix land holdings in the Larder Lake area consists
of two properties which straddle the Larder Lake Break to the
west of the Kerr Addison mine in Virginiatown.
The Winchester property consists of 15 patented mining
claims and 2 unpatented mining claims located on either side of
the McVittie-McGarry Township line, just north of Highway #66.
The 'U 1 Island property consists of 22 leased and patented
mining claims located in the southwest corner of McGarry
Township, on the northeast arm of Larder Lake.
Prospecting and diamond drilling were carried out on both
properties during the mid-30's and 40's.
Our 1987 program began with 16.4 miles of linecutting on the
Winchester property and 12 miles of temporary picket line on the
'U 1 Island property. High resolution magnetometer and VLF-EM
surveys were performed on both properties. As expected, the
combined obstacles of water depth and c lake bottom sediments
obscured most of the geophysical response of the Archean rocks
on the 'U 1 Island property.
A full program of surface exploration is planned for both
properties in 1987. Follow-up on geophysical anomalies,
prospecting, soil sampling, rehabilitation of old showings and
geological mapping will be carried out on the Winchester
property. Diamond drilling will be carried out on the 'U 1 Island
property and, depending on the results of the aforementioned
surface program, the Winchester property.

PROPERTY DESCRIPTION
The Winchester property consists of 15 patented and 2
unpatented mining claims which straddle the boundary between
Mcvittie and McGarry Townships in the Larder Lake Mining Division
of Ontario (fig. 1). Phoenix no longer holds the licences of
occupation for the area covered by Bear Lake with the exception
of two recently staked claims, L953962 and L953963.
The total acreage contained in the group of patented claims
is 492.1 acres on which the annual mining rental amounts to
$246.05.

LOCATION AND ACCESS
The property is located on Bear Lake, midway between the
towns of Larder Lake to the west and Virginiatown to the east.
The winter take-off point from Highway #66 is 3.3 miles (5.3 km)
west of Virginiatown at the south end of Bear Lake. Boats or
canoes can be launched from McGarry Beach, located in the
northwest corner of claim L12233, during the summer field season
A bulldozer road will be scouted up the west side of Bear
Lake in order to increase the access to claim L12231 which was
the focus for much of the diamond drilling carried out in the
40's.
-5-
LOCAL RESOURCES
A. Water
Bear Lake and the smaller surrounding lakes could probably
sustain a mining and milling operation. The water from Bear
Lake is probably not potable.
B. Power
Ontario Hydro's double power line, which services
Virginiatown and the Kerr-Addison mine, crosses the north end
of the property on claims L11982 and L16071.
C. Transportation
The property is located less than 1/8 of a mile (0.2 km)
north and south of Highway #66 and the Ontario Northland
Railway track respectively. Daily air service is available
from the town of Kirkland Lake, about 25 miles (40 km) to the
west.
D. Infrastructure and Human Resources
The Kerr-Addison mine located in Virginiatown, could provide
milling services for a developing mine. The long history of
mining as well as the presence of producing gold mines in the
area insures an experienced work force.

HISTORY
The Cobalt silver rush of 1903 encouraged prospecting which
extended further afield. After examining the area in 1904, H.L.
Kerr decided that further investigation was warranted. Upon
this recommendation Dr. W. Addison visited the Larder Lake area
in 1906. He met a Dr. R. Reddick of Ottawa who was also
interested in
claims respect
years later.

Associated Goldfields Ltd. purchased the Reddick
L1751, L1814, L1839, L1840, L1904 and L1905) and
on claims (L1848, L1849 and L1850). After
urtace diamond drilling, a shaft was sunk and
lateral work was done on each of the claim groups with
disappointing results. It should be noted that the north
cross-cut on the 300 foot level on the Reddick property missed
what woulri becjoi'ie the Kerr-Addison No. 10 orebody by 20 feet.
-7-
Meanwhile in 1914, a gold discovery was made by prospector
Jack Costello along a graphitic fault near Pancake Lake, just
north of the present-day town of Larder Lake.
In 1921, Associated Goldfields Ltd. became Canadian
Associated Goldfields Ltd. ("CAGL") and acquired Costello's five
claims including the discovery claim, L1794. The Costello vein
was traced northeast onto ground held by the Crown Reserve Group
("CRMCL").
CAGL and CRMCL started shaft sinking in 1921 and 1922
respectively. In 1926 CAGL built a mill; the mine produced
S52,295 of gold and silver before closing in March, 1928. A
fairly large low grade orebody was developed at the Crown Reserve
mine before the operation was halted in December, 1928.
In 1930, Proprietary Mines Ltd. acquired the assets of CAGL.
Canadian Reserve Mines Ltd. was formed in 1932 to further develop
the Crown Reserve and Canadian Associated Goldfields mines but
no work was done.
Omega Gold Mines Ltd. took over the two mines in May, 1935.
After underground development work was carried out, a 300 ton
mill was built and was in continuous production until the mine
closed in 1947.
After incorporation in 1936, Kerr-Addison Gold Mines Ltd.
acquired the 3 Kerr-Addison and 7 Reddick claims from Proprietary
Mines Ltd. Four adits were driven into the carbonate zone but
the results were not satisfactory. However, one last deep hole
from surface cut what would become the No. 10 orebody at about
the 300 foot level. It returned a 110 foot intersection
averaging 0.33 oz. Au/ton. Further development work outlined a
large orebody and a 500 ton mill was put into production in 1938.
The mill was expanded until 1960 when production peaked at 4,556
-8-
tons per day. Greater mining depth and a change to cut and fill
square-set stoping reduced the number of working places for
mining and resulted in a reduction in milling rate.
Presently, the Kerr-Addison mine is milling 1,200 tons per
day at a head grade of 0.12 oz. Au/ton with reserves of 955,000
tons .

PREVIOUS WORK
The Winchester property was mapped in detail by H.C. Laird
in October, 1941.
In 1944, 5,600 feet of diamond drilling was performed on the
east side of Bear Lake by Winchester Larder Mines Limited.
In 1946, camps and offices were set up and a surface
exploration program leading up to 2,200 feet of diamond drilling
was performed. A zone of erratic high grade gold mineralization
was outlined on claim L12231. Surface work continued until
around 1950.
-10-
REGIONAL GEOLOGY
The Winchester property is located in the southwestern
portion of the Archean Abitibi Subprovince of the Superior
Structural Province (Fig. 2). The volcanic and sedimentary
rocks of the Timmins-Kirkland Lake-Larder Lake-Noranda area form
a large east trending synclinorium which plunges to the east.
The Destor-Porcupine Fault Zone and the Kirkland Lake-Larder
LakeCadillac Fault Zone transect the northern and southern limbs
of the synclinorium, respectively. Small plutons of
granodioritic to syenitic composition intrude the supracrustal
rocks. Archean to Lake Proterozoic diabase dykes occur
throughout the area. Protero2oic sedimentary rocks of the Cobalt
Group onlap the subgreenschist facies Archean rocks from the
south.
The volcanic stratigraphy consists of a Lower and an Upper
Supergroup (Jensen, 1985). "The Lower Supergroup on the
southern limb of the synclinorium, southeast of Kirkland Lake,
contains a cycle of komatiitic, tholeiitic, and calc-alkalic
volcanic rocks represented by the Wabewawa, Catherine and Skead
Groups respectively."
The property is located within the Upper Supergroup, a
volcanic cycle which consists of "komatiitic lavas of the
Larder Lake Group (Kerr-Addison, McBean, Cheminis, Omega)
succeeded by tholeiitic rocks of the Kinojevis Group and calc-
alkalic rocks of the Blake River Group. Alkalic volcanic rocks
of the Timiskaming Group (Macassa) unconformably overlie the
Blake River and Kinojevis Groups."
The total thickness of the Upper Supergroup is greater than
30 km.

PROPERTY GEOLOGY
The area of the Winchester property has been mapped by P.E.
Hopkins, Ontario Department of Mines 1924, J.E. Thomson ODM 1941
and in detail by H.C. Laird 1941.
A re-drafted version of Laird's geological map is provided
in Appendix l at the rear of this report.
The property is underlain by tholeiitic basalts of the
Kinojevis Group unconformably overlain by trachytic flows and
turbiditic greywackes of the Timiskaming Group. A small late
intrusive of syenitic composition occupies the northwestern
corner of the property.
A 035 0 dextral strike-slip fault splays off the Larder Lake
Break and transects the eastern portion of the property. The
fault appears to truncate the eastern nose of the syenite plug
and therefore postdates the last major phase of alkalic
intrusive activity.
Another large fault can be seen on the aerial photographs
striking just east of north on the western boundary of the
property.

REGIONAL AND LOCAL STRUCTURE
The Larder Lake-Cadillac Fault is the major linear
structural feature in the area. It can be traced from Kenogami
Lake in the west to Val d'Or in the east - a distance of over 90
miles (150 km). The regional strike of the Fault is 090 O ,
dipping steeply south. In Mcvittie and McGarry Townships, the
strike of the fault zone is 060 0 , w
the north at the Kerr-Addison mine.
strike of the fault zone is 060 0 , with an anomalous 70 dip to
The Larder Lake Fault Zone separates the younger Timiskaming
Group to the north from the much older Larder Lake Group to the
south. It also separates two structural domains. North of the
"Break", the down-faulted side, fold axes plunge steeply to the
east. South of the "Break", the up-faulted side, fold axes
plunge moderately to the southwest.
In the property area, the "Break" forms the linear south
shore of Barber Lake and passes between the south end of Bear
Lake and the north shore of Tournene Lake.

PRESENT WORK
The program on the Winchester property comprised 16.5 miles
of linecutting and geophysical surveys. The results of the work
are shown on the following maps found in Appendix l at the rear
of this report:

The total magnetic field strength was measured with an EDA
proton precession magnetometer, PPM-350. Secular and diurnal
drift were corrected by an EDA PPM-400 base station magnetometer
During the survey period the earth's magnetic field was rated
quiet to unsettled by the Geomagnetic Forecasting Service.
The VLF-EM survey was performed with a Geonics EM-16 very
low frequency receiver tuned to the Cutler, Maine transmitter
station.
The geological mapping was carried out by H.C. Laird in
1941.

GEOPHYSICAL RESULTS
Introduction
During the period January 21 to February 22, 1987, Phoenix
Gold Mines Limited performed geophysical ground surveys on the
Winchester property located in McGarry and Mcvittie Townships,
northeastern Ontario.
The program consisted of a VLF-EM survey using a Geonics
EM-16 tuned to Cutler/ Maine and a magnetometer survey carried
out with EDA field and base station proton magnetometers. The
base station was magnetically "tied into" the magnetic survey
carried out on the Phoenix U Island property 1.5 miles (2.4 km)
to the south. Therefore the magnetic surveys of the two separate
properties can be compared to one another.
The surveys were performed on a winter-cut grid. The
baseline was oriented at 064 with crosslines spaced 400'
(121.9 m) apart. Pickets were planted every 100' (30.48 m) while
readings were taken at 50' (15.24 m) and sometimes 25' (7.62 m)
intervals.
Magnetometer Survey
The magnetic survey measured the total magnetic field in
nanotesla (nt) or gammas. The magnetic relief on the property
is fairly profound due to the presence of tholeiitic basalts
(Kinojevis Group) overlain by iron poor alkalic volcanic and
sedimentary rocks (Timiskaming Group).
The tholeiitic basalts on the southeast and northern
portions of the property are outlined clearly by magnetic values
in the 57600 nt and greater range. Magnetic relief is evident
on the large island where the basalts on the east side are
intruded by syenite on the west (mag low).
-15-
The band of Timiskaming greywackes that runs east-west
across the southern portions of claims L12231, 12206 and 12172
show gradually increasing values (in the 57300-57500 range) from
south to north. The Timiskaming alkalic volcanic rocks that
occupy the southern portion of the property show more magnetic
relief than the greywackes. Values range from 57250-58005 nt
with a majority in the 57400 nt range.
The late alkalic intrusive that occupies the northwestern
portion of the property is clearly outlined where it is in
contact with the basalts. Magnetic relief within the plug is
very flat with values ranging from 57450-57600 nt. The small
circular magnetic high on lines 12W to LO, 200'N to 900'N
represents a xenolith of basalt that was rafted into the
intrusive ie. a roof pendant.
The contact between the intrusive and the sedimentary rocks
to the south is not clearly outlined and requires further
mapping.
VLF-EM Survey
The VLF-EM survey measured In-phase dip angle and quadrature
values. The Fraser filter technique was applied to the In-phase
dip angle data which produced data that could be contoured.
Several prominent conductors have been outlined. Most are
due to conductive overburden which has collected in linear
troughs clearly visible on aerial photographs. Examples are as
follows:
L24W 950'N - L8W 480'N
L8W 1800'N - 200'E 1050'N
L24W 800 'S - L44E O'N
-16-
Conductors which do not correspond to air photo linears are
also present. The western portion of the conductor located at
LO 1000S - L40E 1500S lies close to the contact between a small
east-west finger of basalt to the north and greywacke to the
south.
The conductor located between L24W 1450S and LO 1600S may
represent the contact between greywacke to the north and trachyte
to the south.
It should be stressed that the conductors that have been
outlined are, for the most part, due to conductive overburden
within linear topographic lows. The significance of these
anomalies from an exploration viewpoint is the nature of these
low troughs. Contacts between rocks with differing rheological
properties are prime sites for deformation, alteration and
erosion. Fault zones are also often represented on surface by
topographic lows. Indeed many of these contacts are probably
fault contacts.

CONCLUSION^
1. Due to its structural and stratigraphic setting along with
the presence of late alkalic intrusive rocks with inclusions
of country rock, the Winchester property has the potential
to host a "lode gold deposit". Gold mineralization could
occur in veins, fractures, alteration zones, metamorphic
aureoles around felsic intrusions and even as disseminated
particles. Gold mineralization has been found on claim
L12231 in the form of gold tellurides along with pyrite and
galena hosted in a broad east trending mineralized zone up
to 100' (30.48 m) in width within the porphyritic syenite
intrusive.
Gold mines which fall under this category are the mines of
the Kirkland Lake Main Break (eg. the Macassa) which occupy
the same position relative to the Larder Lake Break as does
the Winchester property.
2. As the property is overburden covered in places (especially
within the linear troughs), there could be a considerable
number of mineralized zones yet to be discovered.
-18-
RECOMMENDATIONS
It is recommended that:
1. The Company should file an application for a grant with the
Ontario Mineral Exploration Program (OMEP) of the Ontario
Ministry of Northern Development and Mines.
2. The winter-cut grid should be re-cut and chained, if
necessary.
3. A follow-up on all geophysical anomalies should be performed.
4. The entire property should be prospected by an experienced
prospector.
5. Geochemical sampling of overburden covered areas, especially
the linear topographic lows located in claim L12231 be
performed.
6. All old trenches and showings be rehabilitated and sampled.
7. The geological mapping of Laird 1941, must be tied into the
present grid. If this is possible then mapping should be
performed on claims L36201 and the southern portions of
L12231 and L12206. As well the syenites should be carefully
re-mapped in order to distinguish the different phases, if
present, within the intrusive. If Laird's mapping cannot be
tied into the present grid then the entire property should
be mapped at 200 scale (1:4800).
8. If sufficient signs of gold mineralization are found, then
a bulldozer road should be extended along the west shore of
Bear Lake from Highway #66 to the north boundary.
-19-
9. Linecutting and VLF-EM be carried out perpendicular to the
present grid lines in order to test air photo linears
oriented just east of north.
10. All new showings be stripped, washed, sampled and mapped.
11. An allowance be made for 5,000' (1524 m) of BQ wire-line
diamond drilling.
12. Insure that newly staked claim L953962 be kept in good
standing since it binds the claim blocks on either side of
Bear Lake into one contiguous block (other than for the two
isolated islands).

INTRODUCTION!
During the period April 23 - June 29, 1987, Phoenix Gold Mines Ltd. performed a follow-up surface gold exploration program on the Winchester property in the Larder Lake area.
The purpose of the program was to examine the gold bearing potential of the property in light of the high resolution VLF-EM and magnetometer surveys performed in February 1987.
METHODOLOGY:
The decision was made early in the field season to re-cut the winter-cut grid.
A search for the diamond drill holes of the 1948 Winchester-Larder program was performed early in the season, before the foliage engulfed the DDK casings. The located casings and/or probable DDK locations are shown on the 400 scale map provided at the rear of this report. Two-thirds of the casings were left in place. One casing west of the McGarry Beach road was making water( a possible source of potable water).
Follow-up of geophysical anomalies was completed on the south side of Bear Lake, the two islands and on the north side of the lake from the west boundary to L4E.
Prospecting was completed on the south side of Bear Lake, the two islands and on the north side of the lake from the west boundary to L12W.
Following the June 9 instructions from Head Office to close down the program by months' end, the emphasis was placed on stripping and sampling as many mineralized showings as possible.
The mineralized and altered syenite zone in the NW corner of the property that was drilled in 1948 was the first area to be stripped, mapped, and sampled.
Areas where samples from the scouting work assayed more than 100 ppB Au were then examined.
A total of 10 showings were stripped, washed, sampled and mapped during the period June 10-23.
The results are shown on the detailed trench maps ( 10 scale ) provided at the rear of this report.
RESULTS: Page 2.
The prospecting of the previously described areas did not encounter any economic gold mineralization. Outcrop exposure on the^ property is greater than ^Q%. However, the very prominent ENE treraina linear s are masked by overburden. They appear to be filled by boulder rich ( 3 '-5') material and are most probably faults. Due to the heterogenous nature of the overburden, basal till sampling is not recommended.
The ground follow-up of the geophysical anomalies indicated that the detailed magnetometer survey was very effective in outlining different lithologies. The quartz vein stockwork on L28W, north of Bear Lake was found due to a mag low.
Grab sampling of mafic volcanics (tholeitic basalts?) with 2- disseminated pyrite often yielded assays in the 100-200ppB range. This was surprising and was noticed too late in the program to investigate. Examination of any structural discontinuities within the mafic volcanics (geophysical, topographical) which could serve as a channelway for mineralizing and/or concentrating auriferous fluids should be carried out. As well, the roof pendants of mafic volcanics within the syenite intrusive, outlined by the mag survey should be investigated for signs of gold mineralization in alteration zones, quartz veins or disseminated sulphides.
Page 3
CONCLUSIONS:
The Winchester program was not a thorough and systematic examination of the entire property. Therefore conclusions cannot be made at this time.
RECOMMENDATIONS:
1.) Complete the prospecting and geophysical ground follow-up.
2.) Strip, wash, sample, and map any showings revealed by the previous recommendation.
3.) Tie Laird's geological map to the present grid.
4.) A detailed examination of the mafic volcanics is warranted in light of their anomalously high gold consent, attention to structural discontinuities and alteration zones is required. If these pyrite rich mafic volcanics are found to be auriferous, IP surveys might be able to outline sulphide rich zones.
