INTRODUCTION
l During May, 1988, linecutting, a total field magnetic survey
B and an electromagnetic survey were completed on the 10 contiguous
' unpatented mining claims known as the Frecheville - South
l Property in Frecheville Township, Larder Lake Mining Division.
The property is located in NTS 32D/12 with coordinates of
Longitude 79 34'W and Latitude 48 33'N.
l A total of 16.114 kilometers of linecutting was completed to
establish a total of 1289 magnetic readings and 1129 VLF-EM
l readings. The survey was completed from May 24 to 26, 1988, by
personnel. of Guy Thibault Exploration Services. The data
reductions and drafting was completed by Guy Thibault Exploration
l Services from June 2 to 14, 1988. The interpretation and report
were completed by the author from June 16 to 20, 1988.
lThe project area is located approximately 35 miles (56 km)
l east of Matheson along Highways 101 which is about 11 miles (18
H km) west of the Ontario-Quebec Boundary. The claims cover the
ground to the north of the Lightning River located in the
l southwestern quadrant of Frecheville Township, Larder Lake Mining
Division, District of Cochrane, Ontario.
m The purpose of the survey was to identify the lithological
units, structural features and favourable areas for gold
mineralization.

lLOCATION AND ACCESS
l The 10 unpatented mining claims cover the area north of the
Lightning River located in the southwestern quadrant of
* Frecheville Township, Larder Lake Mining Division, District of
l Cochrane, Ontario as shown in Figure 1.
l The project area is located approximately 35 miles (56 km)
east of Matheson along Highways 101 which is about 11 miles (18
B km) west of the Ontario-Quebec Boundary. Access is by Highway
B 101 East to about l mile past the Frecheville-Lamplugh Township
boundary. At this point a walking trail leads northwards for
l approximately 2.25 miles (3.6 km) to the south claim boundary
covered by this report. The camp and equipment had to be
m transported by helicopter from the highway to the camp site on
j the grid. A logging road in Lamplugh Township comes within about
l mile (1.6 km) of the western claim boundary, however crossing
l the Lightning River is difficult if not impossible.
l PROPERTY
The portion of the St. Joe Canada Inc. holdings covered by

GENERAL GEOLOGY
l All the bedrock is of Early Precambrian age. The oldest
rocks are calc-alkalic metavolcanics composed of basalt and
" andesite, and dacite and rhyolite called the Hunter Mine Group in
B the southwest part of the area between the two branches of the
Destor-Porcupine Fault. These steeply dipping folded rocks are
l overlain by a thick flat lying, factionated komatiitic flows
which consist of massive basal peridotite layer overlain by
m pyroxenite and gabbro similar in composition to magnesium-rich
m tholeiitic basalt known as the Stoughton-Roguemaure Group. The
komatiitic lavas are the basal part of a 10 km thick southeast
l dipping monoclinal komatiitic succession.
l
l
Above the 10 km in the metavolcanic succession, numerous
layers of finely bedded tuff-breccias, tuffs, cherts, argillites,
graphitic sediments, and iron formation appear with the
l tholeiitic lavas of the Kinojevis Group.
The pervasive grade of metamorphism is greenschist to
sub-greenschist facies.
l The triangular syncline in central Frecheville Township
appears to have been formed during the proccess of volcanism.

ll Subsidence occurred along the north branch of the Destor
Porcupine Fault such that to the south, the calc-alkalic rocks
l are closer to the surface. Subsidence also occurred along the
south branch of the Destor Porcupine Fault and to the east.
B Prominent cross faults in the Frecheville area has displaced
the west-northwest trending north branch of the Destor-Porcupine

l
Fault by as much as 500 feet. These faults have orientations of
north-northwest and north-northeast to northeast.
PREVIOUS EXPLORATION ACTIVITIES
l Mineral exploration began with the discovery of gold in 1906
along the shores of Lake Abitibi and in 1917 in Harker and
l Holloway Townships.
During the 1950 's, Dominion Gulf Company and Asbestos
l Corporation explored for asbestos in the ultramafic rocks in the
northern parts of Harker, Holloway, and Garrison Townships and
l the southern parts of Lamplugh and Frecheville Townships. They
m conducted a magnetic survey, geological mapping and two diamond
drill holes on claims which were located to the southwest of the
l present ground held by St. Joe Canada Inc.
l During 1973, L. S. Jensen mapped the general area at a scale
of 1:63,360, Preliminary Map P. 2433 and P. 2432.

INTRODUCTION:
The linecutting was conducted by Guy Thibault Exploration
l Services of Timmins, Ontario, from May 16 to 20, 1988 on claims
. L-803489 to L-803494 inclusively and from May 22 to 24, 1988 on
" claims L-1035751 to L-1035754 inclusively. The 'east-west base
l line was located midway between the north and south property
boundaries with Line O being established at the claim line
g between the existing claim block and the recently staked claims.
The line separation was established at 100 meter intervals along
* the base line and all lines were picketed at 25 meter intervals.
lOn completion of the linecutting, Guy Thibault Exploration
l Services conducted a total field magnetic survey and an
electromagnetic (VLF-EM) survey with the following personnel and
dates: Guy Thibault - VLF-EM survey from May 24 to 26, 1988 and
B B. McAllister - magnetic survey from May 24 to 26, 1988. The
surveys were conducted with the Geometrics G-816 proton
l procession magnetometers and the Geonics EM-16 using Cutler,
Maine as the transmitting station. The instrument specifications
* are located in the Appendix.
lThe data reductions and drafting was completed by Guy
l Thibault Exploration Services from June 2 to 14, 1988. The
interpretation and report was conducted by the author from June
l 16 to 20, 1988.

l *MAGNETIC SURVEY:
l The magnetic base station was established on the Base Line
at Line 2 East with an average base value of 58,023 gammas. The
l base line was surveyed at 12.5 meter intervals in a looping
m fashion to establish accurate control stations for each grid
line. The north-south grid lines were surveyed at 12.5 meter
l intervals. A total of 16.114 km of grid was surveyed to
establish 1289 magnetic oberservations utilizing the Geometric
l G-816 Proton Procession Magnetometer.
The data was corrected for the daily drift and the tie-ins
l at the control stations. A base level of 57,000 gammas has been
removed from all the observed readings.
lH The corrected data was plotted on a base map with a scale of
l cm to 25 meters (1:2500). The data was contoured at 25 gamma
l intervals wherever possible as shown in Figure 3.
l ELECTROMAGNETIC SURVEY:
M The electromagnetic (VLF-EM) survey was completed with the
Geonics EM-16 unit. the transmitting station used for this
l survey was Cutler, Maine with a transmitting frequency of 24.0
kHz. Only the north-south grid lines were surveyed at an
l
l
l
interval of 12.5 meters. A total of 14.114 km of grid was
completed to establish 1129 readings.
l K AJ Kian A. JensenIBP Exploration and Consulting Services
l The VLF transmitting stations create a concentric horizontal
m magnetic field. When this field meets a conductive body, it
generates horizontal fields radiating from the bodies. The EM-16
l unit measures the vertical component of these secondary fields.
l The in-phase and quadrature values in percentage of the
j vertical field are plotted on a base map. The data was plotted
with a scale of l cm to 10% with the In-phase data plotted on the
l left side and the Quadrature data plotted on the right side of
the line. The data is shown in profile form in Figure 4. To
l assist in the interpretation of the VLF-EM survey, a low pass
i filter was done on the in-phase or dip values known as a Fraser
Filtering. The positive Fraser Filtering values which indicate
l conductive bodies are contoured on a base map at an interval of
5% as shown in Figure 5.
lm INTERPRETATION:
The magnetic data values range from the low 57,800 gammas in
l the southwest to a high of 58,100 gammas in the northeast. The
general trend of the magnetic survey indicates the lithological
l units appears to be striking in a west-northwest direction.
The area in the northeast appears to be representing the
l massive mafic metavolcanics. The boundary of this unit appears
to be in the vacinity of 58,050 to 58,100 gammas. Southwest of
l this area, the lithological units appear to consist of felsic to
l intermediate metavolcanics and metasediments. In the very
l
l ;J l l l
l
KA| Kian A. JensenExploration and Consulting Services
southwest corner of the property, it appears that the bedrock
composition may be either a more felsic metavolcanic to
metasedimentary sequence or a calc-alkaic metavolcanic unit.
The major structural feature within the claim block is the
l north-northeast trending fault located at 2+37 mE on the baseline
with the eastern portion being displaced approximately 100 meters
to the south.
lThe anomalies detected from the EM-16 VLF survey and the
B Fraser Filtering has identified a total of 31 conductors lettered
. from "A" to "Z" and "AA" to "AE" as shown in Figure 6. Most of
the conductors are classified as poor to moderate with a few good
l conductors. In several areas, the anomaly is caused by the
overburden composition rather than a bedrock source. In the
l identification of the anomalies, there are not any representing
M faults or shear zones. This is due to the low angle between the
fault zone and the survey grid lines.
l
lM Conductor A and B:
* This appears to be a double conductor with the northern part
l "A" being poor and is probably due to the overburden while the
southern part "B" is a good conductor and is caused by the
J overburden and a bedrock conductive source. It appears that the
top of the conductor is approximately 50 to 60 meters, however,
the interference from conductor "A" may cause this depth to
either increase or decrease.
The analysis of the individual conductors are as follows:
l
l
l
l K AJ Kian A. Jensen^•P Exploration and Consulting Services
l *
. Conductor C:
This moderate to good conductor has a strike length of
l approximately 400 meters and is probably caused by a combination
of the overburden and a bedrock source. The depth to the top of
p the conductor appears to vary from 50 to 55 meters.
Conductor D:
l This is probably caused by the overburden and a weak bedrock
source. The conductor appears to be striking in a west-northwest
J direction and may extend off the property due to the partial
anomalies at the northern ends of Lines 6 West and 7 West. These
' later two partial anomalies indicate a large poor source at
m depth.
l Conductor E:
This good conductor is only 100+ meters long and is on the
B northern side of a bedrock exposure. It appear to be near
B surface and in part may be due to the overburden and swampy
ground conditions.
lConductor F:
It appears that this is a poor one line anomaly, and is
caused by the overburden and bedrock exposure.
Conductor G:
The anomalies are located on the south side of the bedrock
l exposure area and is probably caused by the overburden and
bedrock interface.l
g KAJ Kian A. JensenIBP Exploration and Consulting Services

m Conductor H:
This moderate conductor with a strike length of 200+ meters
l is probably due to the overburden and a moderate bedrock source.
It appears that the depth to the top of the anomalies vary
between 25 and 30 meters.
Conductor I:lI This one line poor conductor is probably due to the
overburden.
l j Conductor J:
This conductor varies from poor to moderate and having a
l probably cause of a bedrock source on the western line, a
overburden and bedrock source on the middle line and a overburden
g source on the eastern line. The depth to the top of the
. conductor is approximately 50 */- meters.
l Conductor K and L:
These good conductors may be related to each other. The
l anomaly K is caused probably by a bedrock source at an
. approximate depth of 25 to 30 meters. The anomaly L which has a
good bedrock source on the west and a poor bedrock source on the
l east indicates that the top is approximately at 30 to 50 meters.
l Conductor M:
This moderate conductor appears to be only one line and only
" a partial anomaly data could be collected. It may be cause by a
B conductive source near the east-northeast trending fault zone.

l *B Conductor N:
* This moderate one line anomaly may be related to M, however,
l the estimated displacement of the fault is approximately 100
meters. The cause of this anomaly may be the same as M. The
f depth is approximately 35 meters.
* Conductor O:
l This moderate conductor probably has a depth to the top of
approximately 50 meters and is probably caused by a bedrock
source.
Conductor P:
This 200+ meter long conductor is poor on the east and good
on the west representing a source of overburden with a depth of
l 30 meters and overburden and bedrock with a depth of
approximately of 75 meters respectively.
B Conductor Q:
The cause is probably the overburden.
lConductor R:
This one line moderate conductor is probably caused by a
combination of overburden and a weak bedrock source.
Klan A. JensenExploration and Consulting Services
j Conductor S:
This 400+ meter long generally moderate to good conductor is
l probably caused by the overburden and a bedrock conductor ranging
in depth from 50 to 75 meters. The eastern portion is probably
l caused more from the overburden than from a bedrock source.
Conductor T:
l The cause of the one line anomaly is probably the effects of

the overburden.
l
l
l
l
l
lConductor W:
l The cause of the 200+ meter long anomaly is probably the
effects of the overburden on the western portion and the moderate
l to good portion is probably due to the overburden and conductive
bedrock source.

l
l KA! Klan A. JensenW0 Exploration and Consulting Services
l Conductor Y:
The 200+ meter long moderate to good conductor is probably
caused from a bedrock source at 50 to 60 meters below surface.
The interpretation is complicated due to the presence of the
conductors to the north.
lConductor Z and AA:
l The 300+ meter long strong, moderate to good conductor
m located near the southern portion of the outcrop area is probably
due to a near surface bedrock source. A possibly parallel to
l sub-parallel second conductor may be presence as indicated by
anomaly AA on Line 9 East.
lmm Conductor AB and AC:
These two conductors are located on the north side of the
l outcrop area are probably caused by shallow overburden source.
g Conductor AD:
mm This strong, moderate conductor is probably caused by a
bedrock source near surface. However, the data is incomplete due
8 to the property boundary.
l
l
Conductor AE:
This weak and poor conductor appears on one line and may be
caused by either the overburden or a lithological contact.

lCONCLUSIONS
l The combination of the magnetic and electromagnetic surveys
conducted on the property has indicated only one major fault zone
l which was identified only in the magnetic survey. The
B lithological units located on the property are the more mafic
metavolcanics to the northeast to the central area of mafic
l metavolcanics and metasediments and finally, the possible
existence of a calc-alkalic metavolcanic unit in the very
8 southwest portion of the property.
Some of the overburden conductors may be in fact caused by
l weak shearing parallel to the strike of the lithology. However,
the strength of the anomalies indicate that the are probably more
l affected by the overburden. Due to the presence of many parallel
m double conductors which cause interference, the depth estimates
are only approximate and the dip of the anomalies are difficult
to determine.
RECOMMENDATIONS
l It is recommended by the author that the new mining claims
to the west be geologically mapped and the better conductors "B
l and C", "P", "S", "Y", and "Z" have additional follow-up
g geophysical surveys conducted. Based upon the results of the
l
l l l l l l l l l l l l l l l l l l l

additional geophysical survey, either a reverse circulation
overburden drilling program or a diamond drilling program may be
warranted.

Operating ManualIHel G -826Portable Proton Magnetometer
1.0 GENERAL INFORMATION
1.1 INTRODUCTION
The Model G-826 Portable Proton Mangetometer is a complete system designed for man-carry field applications requiring simple operation and stable measurements of the total intensity of the earth's magnetic field. The G-826 is accurate and has a sensitivity of i l gamma over a range from 20,000 to 90,000 gammas. Since the instru ment measures total field intensity, the accuracy of each measurement is not affected by sensor orientation. The inherent simplicity of the G-826 proton magnetometer allows rapid, accurate measurements to be obtained from a rugged, compact field instrument. This is a precision instrument and reasonable attention must be given to handling, battery condition, and magnetic environment.
1.2 MAGNETIC ENVIRONMENT
It is important that the earth's magnetic field is not perturbed by allow ing unwanted magnetic objects to come close to the sensor. Such objects include rings, keys, watches, belt buckles, pocket knives, metal pencils, zippers, etc. When the sensor is used on the staff, one gamma surveys are easily performed provided the sensor is kept at a distance of three feet from the operator. When the sensor is used in the backpack, certain articles of clothing and some types of batteries within the console will cause a five to ten gamma heading error in the readings. The G - 826, however, ^ still provides one gamma sensitivity and repeatability despite the presence . ' of such a base line shift. The backpack feature is recommended for use in difficult terrain where "hands free" operation is required. i;
Prior to survey use, objects that are suspected to be magnetic may be checked in the following manner:
1 i
1. Attach sensor to staff and connect coiled signal cable to console. Sensor should not be moved or turned during the test, and the suspected article should be far away initially.
2. Cycle the magnetometer a few times by depressing the READ button releasing and waiting for a reading each cycle.

l
3. Observe measurement readings. Each reading should repeat to 1 gamma. (A slow shift may occur over several minutes due to a diurnal change in the earth's field. )
4. Place the suspected article at the distance from the sensor expected during actual survey operation.
5. Cycle magnetometer several times and note the readings.
6. Remove the article and repeat steps 2 and. 3 to check "fordiurnal shifts in the earth's field. If'a diurnal shift is present, repeat entire test. '
7. If the readings obtained in step .5 differ by more than i l gamma' ( one count) from those obtained in steps 3 and 6, then the . article is magnetic.
IF THE ARTICLE IS HIGHLY MAGNETIC, OR IF THE SENSOR IS INSIDE OR NEAR A BUILDING OR VEHICLE, THE PROTON PRE CESSION SIGNAL WILL BE LOST, GIVING COMPLETELY ERRATIC READINGS AND LOSS OF l COUNT REPEATABILITY.
The magnetometer should not be operated in areas that are known sources of radio frequency energy, power line noise (transformers), in buildings or near highly magnetic objects. The :sensor should always be placed on the staff above the ground, or in the "backpack. " The sensor will NOT operate properly when placed di rectly on the ground.

VLF Electromagnetic Unit
i i i i i i i
Pioneered and patented exclusively by Geonics Limited, the VLF method of electromagnetic surveying has been proven to be a major advance in exploration geophysical instrumentation.
Since the beginning of 1965 a large number of mining companies have found the EM16 system to meet the need for a simple, light and effective exploration tool for mining geophysics.
The VLF method uses the military and time standard VLF transmissions as primary field. Only a receiver is then used to measure the secondary fields radiating from the local con ductive targets. This allows a very light, one-man Instrument to do the job. Because of the almost uniform primary field, good response from deeper targets is obtained.
The EM16 system provides the in-phase and quadrature components of the secondary field with the polarities indicated.
Interpretation technique has been highly developed particularly to differentiate deeper targets from the many surface indications.
Principle of OperationThe VLF transmitters have vertical antennas. The magnetic signal component is then horizontal and concentric around the transmitter location.

Receiving CollsVertical receiving coll circuit In Instrument picks up any vertical signal present. Horizontal receiv ing coll circuit, alter automatic 90 0 signal phase shift, feeds signal Into quadrature dial in series with the receiving coll.
In-Phase Dialshows the tilt-angle of the Instru ment tor minimum signal. Jhls angle Is the measure of the vertical In-phase signal expressed In percentage when compared to the horizontal field.
Quadrature DialIs calibrated In percentage mark- Ings end nulls the vertical quad rature signal In the vertical coll circuit.
Hw l
lselecting a suitable transmitter station as a source, the 16 user can survey with the most suitable primary field
muth.
t EM 16 has two receiving coils, one for the pick-up of the Jrizontal (primary) field and the other for detecting any jmalous vertical secondary field. The coils are thus ortho
gonal, and are mounted inside the instrument "handle".
i actual measurement is done by first tilting the coll bembly to minimize the signal In the vertical (signal) coil and
then further sharpening the null by using the reference signal tabuck out the remaining signal. This is done by a calibrated Quadrature" dial.
The tangent of the tilt angle is the measure of the vertical in-phase component and the quadrature reading Is the signal at right angles to the total field. All readings are obtained in per centages and do not depend on the absolute amplitude of the primary signals present.
The "null" condition of the measurement Is detected by the drop In the audio signal emitted from the patented resonance loudspeaker. A jack Is provided for'those preferring the use of an earphone instead.
The power for the instrument is from 6 penlight cells. A battery tester Is provided.
