1 * l NTRODUCTION
This report presents an interpretation of the geophysical
data on the Gold Seekers Bay claim group of Gold Fields
Resources Canada Limited. The Gold Seekers Bay Area consists
of twenty five claims located in the Gold Seekers Bay area of
Red Lake. The claim group lies in the south eastern quarter
of McDonough Township. The majority of the claim group lies
underwater. The land portion of the claim group lies almost
in the centre of the area and consists of the peninsula which
forms the Post Narrows in the area of Red Lake between Gold
Seekers Bay and Hoyles Bay.
The previously available geological and geophysical data have
been compiled to provide a background basis for analysis of
the current field seasons survey data. The report provides a
brief summary of this information as well as a description of
the ground mag and VLF data which is the main subject of this
report. The data sets have been combined to generate the
interpretation map of the survey area.
Figure l shows the location map indicating the position of
the survey area. The claim numbers for the group are
indicated on this map. The claims define an area which runs
roughly northeast - southwest. This trend parallels the
major geologic strike in the survey area.
2 ' SUMMARY
The Gold Seekers Bay claim group is located towards the
northern edge of the Red Lake Greenstone Belt. In the survey
the regional structure trends northeast-southwest. The rocks
in the area are a mixed sequence of intermediate and mafic
metavolcanics blended with metasediments .

l l l l l l l l l l l l l l l l l l l
October, 1981 2 811-1311
In the survey area the geology is distinctly zoned with a
series of contacts running northeast - southwest. A number
of synclinal and anticlinal axes run parallel to the zoning
of the geology. Bedding planes dip steeply to the northwest
and to the southeast depending on which side of the synclinal
or anticlinal axes the outcrop is observed. Dips tend to be
in the range 70 to 90".
Taking a section running from the northwest to the southeast
across the survey area the following rock types are
encountered. At the very northwest end of the section there
is a wide zone of mafic metavolcanics. The mafic metavol-
canics are in direct contact with a narrow band of interme
diate volcanics, which abut a zone of clastic metasediinents
to the southeast. Next comes another band of mafic volcanics
followed by another zone of clastic metasediments. The
survey area is bounded on the south by a third zone of mafic
metavo]canics. The contacts between the mafic metavolcanics
and the clastic metasediments are frequently characterized by
a narrow zone of what are called chemical metasediments. The
chemical metasediments consist of chert, iron formation,
pyrrhotite, pyrite, graphite and marble.
At the very northeast end of the survey area the normal
geologic sequence is disturbed by a zone of basic to ultra
basic intrusive rocks consisting mainly of gabbro, perido
tite and pyroxenite At the southwestern end of the survey
area, a small granodiorite intrusive is observed on the
shore line. The granodiorite intrusive has mineralization in
the vicinity of the contact with the metasediment. Gold,
chalcopyrite, arsenopyrite, pyrite, sphalerite, and galena
are observed. Further detailed information of the geology
can be obtained by reference to the Ontario Geological

Survey Preliminary Map PI 24 O for McDonough Township. Since
the survey area is primarily covered by water it is difficult
to assess the continuiuty of the geological structure out
from the shore line. From the regional magnetics and the
general lineation of the structure it would appear that the ,
general zonings which run northeast - southwest carry on
underneath the water with little discontinuity.
3. SUMMARY OF GEOPHYSICAL DATA
3. 1. Etistin Data
The geophysical data previously available for the Gold
Seekers Bay claim group consists of the airborne magnetic and
INPUT survey carried out by the Ontario Geological Survey in
1978. The maps presenting this data for the area of interest
are the OGS Preliminary Maps Nos . 1571 through 1574. The
portion of the map sheet 1572 directly applicable to the Gold
Seekers Bay claim group is shown in Figure 2.
The airborne rnag shows two strong magnetic zones which
trend northeast-southwest. These magnetic highs flank a zone
of lower mag response which conincides with the main part of
the current survey area. The magnetic highs peter out towards
the southwest part of the survey area. The INPUT data shows
a large number of 5 and 6 channel anomalies. The conductors
follow the regional geological strike. The conductor zones
appear to run right across the whole survey area from
southwest to northeast. The general nature of the mag and
the INPUT responses are typical of the iron formation type
responses observed over the whole Red Lake Greenstone Belt
Area.

3.2 Ground Survey Work
The ground survey work for the Gold Seekers Bay claim group
consists of a combined VLP and magnetometer survey carried
out by Phoenix Geophysics for Gold Fields Resources Canada
Limited. The survey work was carried out in April of 1981
and, since the majority of survey area is water covered, the
survey was carried out on the ice before breakup in the
spring.
The survey work for the area was laid out with a base line
running parallel to the geologic strike. Zero on the base
line is at the southwest corner of the area. The survey work
was carried out on 30 northwest-southeast trending lines
spaced 400 ft. apart. The lines run northwest and southeast
from the base line to the edge of the claim group area. A
total of 22.7 line miles were surveyed including the base
]ine comprising a total of 1055 VLF stations and 1115 mag
stations. The VLF and mag station interval was nominally
100 ft.
The magnetometer survey was carried out using the geometrics
G-816 magnetometer and MR-10 base station mag. The mag data
were corrected for diurnal drift by differencing the survey
data and the base station data in the conventional manner.
The magnetometer results are shown in contoured form in
Figures 3 and 4. In view of the odd shape of the claim group
area it has been necessay to split the display of all ground
survey data into two parts. Part one of the survey area
consists of the southwestern half of the claim group whereas
part two of the area consists of the northeastern part of the
claim group. The general features of the ground survey data
corroborate the results of the airborne mag survey. A number
of localized strong magnetic responses are observed scattered
over the whole survey grid.

The VLF survey was carried out using a Phoenix VLF-2 unit
operating on Seattle, Washington at a frequency of 18.4 khz.
The Seattle, Washington station is located west of the survey
area which results in the VLF signals being optimally coupled
to east-west striking conductors. The data collected at each
station consisted of total horizontal magnetic field strength
and dip angle of the VLF magnetic field. The total
horizontal field strength, which has been corrected for
station and receiver drift, is shown along with dip-angle
data in Figures 5 and 6. The instrument has been calibrated
to read 150 units at a fixed reference point in a background
zone of the survey area. The data read from the instrument
have been plotted directly on to Figures 5 and 6 and have
been contoured. No attempt has been made to convert the
horizontal field strength into the percent variation in field
strength. Areas of high horizontal field strength are
indicated by values in excess of 150 units while low areas
are those with values less than 150 units. For contouring
purposes the horizontal field strength is contoured for
values above 200 or under 100 units. The intermediate range
of data values tends to be quite erratic and is consistent
with normal background fluctations and noise.
The dip-angle data is also shown in profile form on Figures
5 and 6. The format for the correct selection of crossovers
is indicated in the legend on the side of Figures 5 and 6.
Examining the data for both field strength and dip angle
crossovers, large amplitude dip-angles and sharp crossover
regions are frequently accompanied by increased horizontal
field strength.

October, 1981 6 811-1311
The dip-angle data for the area has also been treated with
the conventional Fraser filter. The results of the Fraser
filter processing are shown in Figures 7 and 8. Only the
positive going output of the filter has been contoured.
In general, the VLF data shows strong conductors are
frequently coincident with strong magnetic responses. In
comparing the VLF data to the geology it would appear that
the conductor axes follow major geologic contacts in the
area. Most of the conductors run continuously across the
survey area southwest or northeast. At the very top of the
Gold Seekers Bay there appears to be some bending of the
conductor axes. This could be indictive of east-west
faulting in the area.

The interpretation of all available data has been carried out
at two levels. In the first stage a general overview of the
major features of the property are presented. In the second
stage a more detailed synopsis of the distinctly anomalous
zones is given. The available data has been synthesized into
a single map using the following steps.
a) All features having mag responses which are in excess
of 1500 gammas and/or which exhibit distinctive trends
are indicated by light shading.
b) Discrete high intensity mag anomalies exceeding 2000
gammas are indicated by more heavily shaded zones.

c) All INPUT anomolies from the OGS survey have been
indicated on the interpretation map using the standard
plotting convention of Questor Surveys.
d) VLF conductor axes have been picked from the Fraser
filter data and are indicated by heavy dotted lines.
Zones of very strong response are indicated by solid
heavy lines. A strong VLF response is characterized by
having a Fraser filter output in excess of 30 units
with an accompanying high horizontal field strength.
e) The VLF conductor axes provide the best means for
identifying important zones in the area. Each conductor
has been numbered in order to facilitate discussion in
the following text. The numbering scheme for the
conductors starts at the northwest side of the property
and increases towards the south eastern edge of the
property.
f) The shoreline of Red Lake has been indicated on all the
survey data maps.
Interpretation maps for the area are shown in Figures 9 and
10. Figure 9 deals with the southwestern portion of the
area whereas Figure 10 indicates the results for the
northeastern portion of the claim group.

4. l General Features
The geophysical data reflects the general structural features
and geologic contacts in this area. All the VLF conductor
axes trend northeast-southwest. The majority of the
conductors appear to be associated with either contacts or
synclinal and anticlinal axes. The magnetic responses are
generally more discontinuous than the VLF conductors. The
magnetic contour-map is composed of a number of localized
highs which generally tend to be elongated in the northeast-
southwest strike direction.
The majority of the strong VLF conductors and mag highs are
directly correlated to mapped zones of chemical metasedi-
ments. The rnag highs must be related to localized zones of
magnetically rich iron formation. The conductors are an
expression of the combined iron formation plus graphite and
possible sulphide occurrences.
There are two main features of the overall integrated data
which are worthy of note. The first feature is the abrupt
turning of the conductor axis at the most northern part of
the survey area. Conductor 3 has a primarily northeast-
southwest trend in claim blocks 541448 and 541449. The
conductor swings markedly to an east-west trend in claim
block 541450. The conductor axis has an associated magnetic
response which shows the same kind of swing as observed in a
zone of intermediate metavolcanics which runs through this
area. The deformation in the rnag anomaly and the conductor
axis could well be associated with the basic intrusive found
farther to the northeast.
The second feature of note is a set of 3 inferred faults
which cut across the south western portion of the claim
block.
Golder Associates
l l l l l l l l l l l l l l l l l l l
October, 1981 9 811-1311
The most northerly fault strikes slightly south of east and
appears to extend right across the entire claim block. The
faults are inferred from the deformation of the conductor
axes and also from the deformation in any linear mag features
which run through the area. The most northerly inferred
fault is a strong feature on the aeromagnetic data and can be
seen continuing far to the east and to the west of the claim
block area. A fault has been mapped in the outcrop east of
Post Narrows directly on strike with the most northerly fault
zone. The other two inferred faults are much less
pronounced. Faulting is also observed to the east of Post
Narrows in areas where outcrop is found.
The INPUT conductors show a good correlation with the VLF
conductor axes. In general the INPUT conductors axes show all
the same features as VLF responses. Two INPUT conductors
both parallel shores of Gold Seekers Bay. The amplitude of
both of these conductors vary significantly as the flight
direction alternates back and forth. This type of response
would suggest that the conductors are dipping. The south
eastern conductor would appear to be dipping to the northwest
while the northwesterly conductor would appear to be dipping
to the southeast. Such behaviour is consistent with the
tightly folded geology in the area.
4.2. D e tajH ̂ ^ J^JLsj^u ssion
Each of the main VLF conductor axes identified on the
interpretation map is discussed in detail. The discussion
consists of noting the correlation of the conductor with the
magnetic response and with the observed geology in the area.

Conductor 1^
Conductor l is a weak VLF response located at the edge of a
magnetic high in the northern part of the claim block. The
only outcrop in the area is a coarse grained gabbro.
CjDnductoj 2^
Conductor 2 runs through a zone of inferred mafic inetavol-
canics. There is no mapped feature directly associated with
the magnetic response for this conductor. Although there is
no geologic indication as to the source of this conductor,
just west of the claim block area there is a zone of iron
formation.
CjDndjuctor 3^
Conductor 3 appears to be directly related to an iron
formation which lies along the contact between mafic and
intermediate volcanics. This conductor appears to continue
on to the southwest and join with conductor 3a. There is a
strong magnetic response associated with this conductor
a]though the conductor axis does not follow the magnetic high
in detail. The main feature of note is the bending of the
conductor axis at its northeast end. Here the strike
directions turns from northeast to east. The southwestern
extension of conductor 3 probably defines the contact between
the mafic and intermediate metavolcanics in the area. The
source of the anomalous response is most likely the chemical
metasediments, discussed earlier, with iron formation and
graphite being the chief source of conductive response.
Silver, pyrite, and pyrrhotite mineralization are noted at

the point where this conductor axis swings from northeast to
easterly in direction.
^PnJLu9tor 4
Conductor 4 appears to run along a synclinal axis in the zone
of intermediate metavolcanics. At the northeast end of the
conductor axis, there is a strong magnetic association. At
the southwestern end of the conductor, the response also
picks up. It appears to be flanked by a magnetic high which
is offset about 200ft. to the northwest. There is a possibi
lity that the conductor could merge with conductor 3a.
Insufficient data is available to infer the connection in
this area.
Conductor 15
Conductor 5 is a long strike length zone which is generally
weak in nature. Three localized zones of high response are
noted along the strike-length. There does not appear to be
any strong magnetic correlation with this conductor.
Correlation with the geology suggests that this conductor
lies along an anticlinal axis in the zone of mafic
metavolcanics. Conductor 5 may be the offset continuation of
conductor 6. A fault is inferred to cut across the area in a
slightly north of westerly trending direction between
conductor 5 and conductor 6. Conductor 6, however, has a
magnetic response associated with it which suggests it could
have a different origin.
Conductor j3
Conductor 6 parallels the northwest shore of Gold Seekers
Bay. It has a magnetic high along the same strike direction.
While this anomaly could be generated by some shoreline

effect it is more likely a localized zone of iron formation
which generates the anomaly. A weak conductor is noted just
south and west of the southern end of the conductor 6.
This conductor, denoted 6a, could be an offset section of
conductor 6. A fault is inferred to run through this zone.
Cond uc tor'T.
Conductor 7 is associated with an iron formation which runs
along a good deal of its extent. In the southwest part of
the claim block the conductor is weak and it does not appear
to have any magnetic association. The conductor peters out
around line 24 N. Towards the northeast,the conductor
appears to merge with conductor 5. A strong response is
noted on lines SON and SON where iron formation and other
related chemical metasediments have been mapped. A strong
magnetic correlation exists in this zone of high
conductivity.
Concluctor^ 8^
Conductor 8 is a single ]ine anomaly located over a strong
mag high. Since the conductor is located in the middle of
Gold Seekers Bay there is no geologic indication as to its
source. From the high mag responses, the source is more than
likely a localized zone of iron formation.
Conductor 9^
Conductor 9 is a weak response with no mag correlation. The
conductor axis parallels that of conductor 10. Conductor 9
appears to be cut off at both ends by inferred faults. As
this conductor is also located in the central part of Gold
Seekers Bay with no shore line continuation it is difficult
to assess the source of this anomaly.

Ccsnd u c tor 10
Conductor 10 i s a weak but distinct zone which runs the whole
length of the property from the very southern edge to the
very north eastern corner. The conductor axis appears to be
disrupted in the area of inferred faulting. Only one zone of
high response is observed and that is at the shore line of
Hoy]es Bay on lines SON and 84N. This conductor appears to
be associated with a synclinal axis which runs along the zone
of intermediate metavolcanics.
C on due t qr^ 1J^
Conductor 11 and lla appear to be a continuous conductor
running the length of the property in a northeast-southwest
direction. There is a strong mag correlation with this cond
uctor axis. The VLF response appears to pick up in zones of
high magnetic response. This conductor appears to follow a
contact between intermediate and mafic metavolcanics.
Distinctive VLF and mag response would suggested iron forma
tion and other related chemical metasediments are located
along this contact zone. No outcrop indicating this char
acter is shown on the geological map of the area.
Cc^nductor 1 2^
Conductor 12 is a weak anomaly which appears to have some
minor magnetic association. It runs from off-shore in the
southwest to onshore on the peninsula which parallels Post
Narrows. Directly on strike with this conductor but much
farther to the southwest is an amphibole-rich flow with some
associated iron formation. This flow is narrow and appears
to align with the conductor.
Golder Associates
l l l l l l l l l l l l l l l l l l l

Conductor 14 shows that a strong conductive response runs
along the northern flank of a northeast southwest trending
magnetic high. While this feature is under water in the Post
Narrows zone, there is an indication of iron formation just
northeast and on strike with this conductor.
C qnc3 uc tor L5
Conductor 15 is a short strike-length, large amplitude
anomaly. It is located on the southeast side of the same
mag feature which parallels conductor 14. It is probably
associated with another localized zone of high conductivity
in an extensive zone of iron formation.
Conductor 1
Conductor 16 is a weak response observed on lines 32 north
and 36 north. There is no apparent mag correlation with this
conductor. There could be any number of sources for this
conductor such as a small zone of pyrite, pyrrhorite or
graphite associated with iron formation located to the north
west, or just the thickening of bottom sediments in Post
Narrows .
5 - SUMMARY, CONCLUSIONS AND RECOMMENDATIONS
The geophysical results appear to reflect the structure of
the area very well. This aspect of the data is extremely
useful in continuing the onshore observed geological features
under the water covered areas of Hoyles Bay and Gold Seekers
Bay. The dominant mag and EM responses appear to be
Golder Associates
l l l l l l l l l l l l l l l l l l l
October, 1981 15 811-1311
associated with iron formations which are situated at the
contact between mafic volcanics and clastic metasediments.
A number of drill holes are indicated on the OGS Preliminary
Geologic Map for the area. The drill holes, a majority of
which are located in Gold Seekers Bay, could provide valuable
information on diagnosing the exact nature of the conductor
sources in the water covered area. The logs of these drill
holes should be obtained if at all possible, in order to
assist with further interpretation of the data.
There are two areas which bear further investigation in
detail. The first area to be investigated is the area in
claim blocks 541449 and 541450 at the very northern edge of
the claim group. The possibility of localized heat from the
basic intrusions to the northeast could have caused remobili-
zation of economic mineralization. Since mineralization is
already observed in outcrops in the area, this zone is of
particular note.
The second area of interest is the major fault zone which
appears to run across the upper end of Gold Seekers Bay
intersecting the base line between lines 52N and 56N. This
feature may have been a controlling factor in the mobiliza
tion and concentration of economic mineralization.
At this point in time, it is difficult to recommend any addi
tional geophysical survey work which might outline further
areas of interest. The most practical next step is to carry
out a drilling programme to investigate some of the more
Golder Associates
l^ October, 1981 16 811-1311
linteresting features of the area. At that time, further
ground EM survey work might be carried out with a
horizontal-loop system to better define conductor axes and
conductor dips before finalizing the drilling programme.
