REGIONAL GEOLOGY
The following is quoted from Abernethy, 1988:
"The Cross Lake Minerals Ltd. properties lie within the Archean
Abitibi Volcano-sedimentary greenstone belt of Northeastern Ontario.
The Currie-Bowman area is dominated by east-west trending steeply
dipping volcanic rocks and tuffs with minor interflow sedimentary
rock. Regional metamorphic grade ranges from lower to upper
greenschist facies.
A regional lithogeochemical survey has identified three distinct
volcanic groups in the Currie-Bowman Area consisting of the Komatiitic
Stoughton-Roguemaure Group (possibly Lower Tisdale Group) in the
northern half of the area, the tholeiitic Kinojevis Group in the lower
half of the area, and the central un-named calc-alkaline Group. The
Cross Lake Minerals properties straddle the boundary between the

Regional economically important deposits which lie at or near the
same stratigraphy as the Cross Lake property are the Tillex Cu-Zn-
Pb-Ag-Au deposit in Currie Township, the Unigold (ex Seaway Copper
Mines) Zn-Pb-Au deposit in Bond Township, the Ross Au Mine in Hislop

PROPERTY GEOLOGY
The following is quoted from Abernethy, 1988:
"The Cross Lake Minerals properties are extensively covered by
overburden and swamp deposits with only 196 outcrop. Outcrops
consist of mafic intrusive and extrusive rocks, intermediate to felsic
intrusive to pyroclastic rocks and diabase.
Mafic intrusive rocks were found in two locations. An outcrop
in the southwest corner of claim number 949456 consisted of a dark-
green, medium to coarse-grained, massive gabbro. The outcrop was
non-descript showing no obvious foliation, weak jointing at erratic
angles and no quartz veining or significant alteration. A second
similar appearing outcrop of gabbro occurred in northwest quadrant
of claim number 1030656 of Grid #4. The gabbroic rocks may represent
coarser-grained phases of thick mafic flow rocks or may represent
separate distinct subvolcanic feeder chambers of the chemically
equivalent massive flows of the tholeiitic Kinojevis Group.
Komatiitic to tholeiitic basalts are the most common lithology
found on the southern claims of the properties. The basalts are
i
if"..:

variably jet black to grey to pale green, fine-grained, massive to
moderately foliated, magnetic to non-magnetic and variably
carbonatized, silicified and chloritized. Pillow basalts and flow
breccias were found only in rocks of Grid #5. The variable appearance
and chemistry (komatiitic to calc-alkaline) of basalts in concessions HI
and IV of Bowman and Currie Townships suggest the existence of an
inter digitated transition zone from the un-named calc-alkaline Group
to the north and the tholeiitic Kinojevis Group to the south'.
Intermediate to felsic pyroclastic rocks were found on the flanks
of a resistive diabase dyke in lots 7 and 8 of concession V in Bowman
Township. The pyroclastic rocks range from very coarse-grained
volcanic breccia/agglomerate to fine-grained ash tuffs and crystal
tuffs. In the southwest corner of claim 948865 is a low density, very
coarse-grained agglomerate containing sub-angular porphyritic,
monolithic autobrecciated clasts in a siliceous, feldspar crystalline
matrix. The agglomerate is bleached white on weathered surface and
pale chloritic green on fresh surface with minor quartz vein stringers
and traces of IX pyrite and chalcopyrite. A large outcrop near the
northern boundary of claim 948865 consists of a black, fine-grained,
well banded cherty/siliceous ash tuff. The essential pyroclasts are
fine-grained (.5-2 mm) lithic fragments, feldspar crystals and, rarely,
quartz shards, in an aphanitic siliceous matrix. The rock is thinly (1-
5 cm) bedded, trending east-west and dipping between 50 to 60
degrees to the south.
Two similar appearing feldspar porphyry outcrops are on the
north boundary of claim 996899 and near the western claim line of
l iii'

claim 948860. The feldspar porphyry is buff white on weathered
surface, coarse-grained, massive, and intermediate in composition. The
feldspar phenocrysts comprise 40-60)1 of the rock and are medium-
grained (1-5 mm), zoned, euhedral plagioclase crystals in an aphanitic
green chloritic matrix. The rock is variably carbonatized with very
minor quartz vein stringers and traces of pyrite and, in the claim
group l porphyry, traces of chalcopyrite.
A large resistive olivine diabase dyke outcrops in the southeast
corner of Grid #5 and continues northeastward to the western part of
Grid #1. The diabase is rusty tan on weathered surface and dark
green/black on fresh surface, ophitic, medium-grained, massive and
moderately magnetic."
PREVIOUS WORK
The following is quoted from Abernethy, 1988:
"Owing to the strategic location (centred between the prolific
Porcupine and Kirkland Lake mining camps) and easy access, all
outcrops in the map area have been extensively prospected and
evidence of previous work such as blasted pits can be found at most
outcrops. Prospecting previous to the early 1970*8 had centred on
gold with the reported occurrence of several gold showings
immediately adjacent to the Cross Lake property, With the Tillex
syndicates' Cu-Zn-Pb-Ag-Au discovery on the Currie-Bowman
Township property in 1974, the area was also recognized as a potential
base metal environment. Due to extensive sand, clay and till cover in
the area (less than IX bedrock exposure) most of the recent

prospecting has been restricted to deep sensing geophysical
techniques and overburden geochemical techniques in addition to
several diamond drill programs on, and adjacent to the properties.

SURVEY PROCEDURE
MAGNETICS
Theory
The magnetic method is based on measuring alteration in the shape and
:m magnitude of the earth's naturally occurring magnetic field caused by changes in
v the magnetization of the rocks in the earth.
i : These changes in magnetization are due mainly to the presence of the
. . magnetic minerals, of which the most common is magnetite, and to a lesser extent
I*
ilmenite, pyrrhotite, and some less common minerals.
tt . Magnetic anomalies in the earth's field are caused by changes in two types
of magnetization: induced and remanent (permanent). Induced magnetization is
l caused by the magnetic field being altered and enhanced by increases in the
magnetic susceptibility of the rocks, which is a function of the concentration of the
;| magnetic minerals.,.v
I Remanent magnetism is independent of the earth's magnetic field, and is the
.: ; , permanent magnetization of the magnetic particles (magnetite, etc.) in the rocks,
l This is created when these particles orient themselves parallel to the ambient field
when cooling. This magnetization may not be in the same direction as the present
earth's field, due to changes in the orientation of the rock or the field.
The most common method of measuring the total magnetic field in ground
exploration is with a proton precession magnetometer. This device measures the
effect of the magnetic field on the magnetic dipole of hydrogen protons. This
dipole is caused by the "spin " of the proton, and in a magnetometer these dipoles
in a sample of hydrogen-rich fluid are oriented parallel to a magnetic field applied
by an electric coil surrounding the sample. After this magnetic field is removed,
the dipoles begin to process ( wobble) around their orientation under the influence

of the ambient earth's magnetic field. The frequency of this precession is
proportional to the earth's magnetic field intensity,
Field Method
The magnetics data was collected with an EDA PPM 350 proton procession
magnetometer, which measures the absolute value of the earth's magnetic field to
an accuracy of l gammas. The magnetometer was carried down the survey line
by a single operator, with the sensor mounted on an aluminum pole to remove it
from any surface geologic noise. Readings were normally taken at Hdm intervals,
and at 12.5m intervals where a high gradient or anomaly was observed by the
operator.
The readings were corrected for changes in the earth's total field (diurnal
drift) with an EDA PPM 400 base station magnetometer, which recorded readings
every 20 seconds as the survey was being conducted. The data from both
magnetometers was then dumped with a computer and base corrected values were
computed.
SURVEY PROCEDURE
MAX-MIN II
Theory
The Max-Min II is a frequency domain, horizontal loop electromagnetic (HLEM)
system, based on measuring the response of conductors to a transmitted, time
varying electromagnetic field.
The transmitted, or primary EM field is a sinusoidally varying field at any
of five different frequencies. This field induces an electromotive force, (emf), or
S voltage, in any conductor through which the field passes. This is defined by:
(the Faraday Induction Principle)
i iii
t ii ii
i i
-9-
where E is the electric field strength in volts/metre (and so fa.dl is the emf
around a closed loop) and jtf is the magnetic flux through the conductor loop. This
emf causes a "secondary" current to flow in the conductor in turn generating a
secondary electromagnetic field.
This changing secondary field induces an emf in the receiver coil (by the
Faraday law) at the same frequency, but which differs from the primary field in
magnitude and phase. The difference in phase (the phase angle) is a function of
the conductance of the conductor(s), both the target and the overburden and host
rock.
The magnitude of the secondary is also dependant on the conductance, and
also on the dimensions, depth, and geometry of the target, as well as on the
interference from overburden and the host rock.
f - These, two parameters (phase angle and magnitude) are measured by
measuring the strength of the secondary field in two components: the real field
or that part "in-phase" with the primary field; and the imaginary field, or that part
in "quadrature" or 90 degrees out of phase from the primary field.
The magnitude and phase angle of the response is also a function of the
l frequency of the primary field. A higher frequency field generates a stronger
:m response to weaker conductors, but a lower frequency tends to pass through weak
v conductors and penetrate to a greater depth. The lower frequency also tends to
energise the full thickness of a conductor, and gives a better measure of its true
conductivity-thickness product (conductance).
For these reasons two or more frequencies are usually used; the lower for
penetration and accurate measure of good conductors, and the higher frequency
for strong response to weak conductors.

li i i i
li.j
l liii
M
ii
-10-
Distinction between conductive targets, overburden/ and host rock responses
are made by studying the shape of the secondary field, and the difference in the
frequency responses.
The transmitted primary field also creates an emf in the receiver coil, which
is much stronger than the secondary, and which must be corrected for by the
receiver. This is done by electronically creating an emf in the receiver, whose
magnitude is determined by the distance from receiver to transmitter as set on
the receiver, and whose phase is derived from the receiver via an interconnecting
wire.
Field Method
The Max-Min II survey was carried out in the "maximum coupled" mode
(horizontal co-planar). The transmitter and receiver are carried in-line down the
survey line separated by a constant distance (in this case 150m) with the receiver
leading. Three transmitter frequencies were used: 444 Hz, 1777 Hz and 3555 Hz
and readings were taken every 25m. The transmitter and receiver are connected
by a cable, for phase reference and operator communication,
SURVEY PROCEDURE
INDUCED POLARIZATION/RESISTIVITY
Theory
The induced polarization (IP) and resistivity exploration methods are
electrical methods based on measuring the response of the earth to an applied
direct current.
The principle is to apply a known electric current to the earth, and measure
the electric potential created by it at the survey location. The resistivity, a bulk
property of the rock itself, is calculated from the difference between the applied
i iii
. -,
li ii
iii ii
i
-11-current and the measured potential, corrected for the geometry of the current and
potential electrode configuration.
The induced polarization measurement is based on the "over-voltage" effect.
Most of the electric current carried by the earth is conducted by the flow of ions
in the solutions filling the pore spaces in the rock. At the surface of any metallic
particle in the path of current low, the ionic flow in the solution is changed to an
electronic flow in the metal. In the process of the change, an electric charge of
trapped ions is built up at the surface of the metal, storing a small voltage. If the
voltage increases, the apparent resistance of the rock also increases. If the
applied current flow is decreased or stopped, the voltage will create a potential in
the opposite direction to the original applied current, and start a current flowing
in the opposite direction.
In time domain induced polarization the applied current is abruptly stopped,
and the reverse potential created by the over-voltage effect is measured over time
as it quickly decays. The definition of chargeability is:
M = y (t :ao) - v (t = o) v(t rooj
where V(t = O) is the voltage at turnoff, and V(t zoo) is the late-time voltage. This
is usually measured over a certain time period after turn-off as an integral of
voltage over time, corrected for the length of the time period, and normalised to
the voltage at time O. It is usually expressed in millivolts per volt (mV/V),
The over-voltage charge taken time to build-up or decay, so that if the
applied current is caused to oscillate more and more frequently, the apparent
resistance will decrease, as the over-voltage does not have time to build at higher
frequencies. This effect is used to measure the IP effect in frequency domain IP
surveys, wherein the current is applied at two or more frequencies, and the
l
lliliit i i
v .
i ii ii l*r.. .

"percent frequency effect" (PFE) is calculated from the change in resistivities (P)
between the different frequencies.
PFE = P (low freq) - P (hiffh frea) x 10(M P (high freq)
Although not identical, for most purposes the PFE is approximately equal to
the chargeability.
Because the IP effect responds to effects on small metallic particles, it is
particularly useful for detecting disseminated metallic minerals. Also because of
this, it will respond strongly to the "membrane polarization" created by the electric
charges resident on clay particles or layered or fibrous minerals,
Field Method
The survey was conducted using a pole-dipole array with a dipole length of#
25m and array spacings of n = 1,2,3,4, dipole and dipole length of 50m and array
spacings of n - 1,2,3,4. These array configurations involve having a dipole for the
receiver measuring Vp, the potential and a single current transmitter electrode on
the grid, separated from the receiver dipole by each 'n' interval in turn. The
other current electrode, 'the infinity' is situated 2 kilometers or more from the
grid.
For this survey the measurements were taken in the time domain, BO the
transmitted current was a bipolar on-off square wave with each on or off lasting
two seconds. Measurements of resistivity and chargeability were taken.

INTERPRETA TION
The results of the surveys are presented for each grid and summarized on
interpretation maps for each grid. Magnetic domains are interpreted by large
zones of distinct magnetic signature and are denoted Mnk, where n is the zone
subscript and k is the grid subscript; for instance M12 would refer to magnetic
zone l of grid 2. Lithological contacts are interpreted at the boundaries of some
magnetic domains. Faults are interpreted by breaks in the magnetic signatures.
Electromagnetic conductor axes are denoted Ak or Bk, where k is the grid
subscript.
Grid l (Figures 4a, 4b, 4c, 4d and 4e) Magnetic Survey
Most of this grid is characterized by a low magnetic relief with values
ranging from 500 gammas over base level to isolated areas where the magnetic
signature is 1500 to 2000 gammas over base level. The general trend of the
interpreted magnetic domains of this grid is northeast, A gradual transition is
observed from low magnetic signature (Mil) in the south-central part of the grid
to medium magnetic signature (M21) in the north-central part of the grid. However,
it is difficult to discern any clear northeasterly trending lithological contact
between Mil and M21, its location remaining very subjective. This transition is
interpreted to represent a possible gradation between the un-named calc-alkaline
Group to the south interpreted by Jensen and Baker (1986) and the Stoughton-
Roquemaure Group to the north (Abernethy, 1988). A few linear bands of higher
magnetic signature (M21) are interpreted within Mil.
Three sets of faults are interpreted, their respective trends are 065, 090 and
110. Due to lack of magnetic relief, it is difficult to estimate the relative ages of
these faults.

HLEM Survey
The electromagnetic survey delineated two weak conductor axes denoted
respectively A1-A1 and B1-B1. These axes coincide with INPUT BM anomalies
delineated by the airborne survey (OGS, 1984) and are interpreted to possibly
represent sulfide horizons within possible felsic pyroclastic rocks. However, these
HLEM anomalies are much weaker than would be expected considering the
conductivity-thickness products interpreted by the airborne EM survey.
Conductor A1-A1 is delimited by an interpreted fault.
Grid 2 (Figures 5a, 5b, da and tib) Magnetic Survey
The magnetic relief of this grid is relatively high, ranging from a low of
approximately 500 gammas above base level in the northwest corner of the grid as
expressed by magnetic domain M12, to a high of approximately 2000 gammas above
base level as expressed by M32.
Magnetic domain M12 is characterized by a low magnetic signature and has
a semi-circular shape. It is therefore interpreted to possibly represent a felsic
intrusive body. Magnetic domain M22 has a signature of medium intensity, with an
average of 1500 gammas above base level and dominates in area the property. It
is interpreted to possibly represent mafic volcanic units within the Kinojevis Group.
Magnetic domain M32 has a high magnetic signature with an average of 2000 gammas
above base level, it is interpreted to possibly represent mafic to ultramafic units
within the Kinojevis Group.
Two sets of faults are interpreted, their respective trends are 085 and 110.

Induced Polarization Survey
The short survey delineated a weak chargeability anomaly near the contact
between M12 and M22. This anomaly is interpreted to possibly represent a sulfide
horizon at the felsic/ma fie contact. The absence of several data points on the
pseudo-section does not allow a good definition of this anomaly.
Grid 4 (Figures bc, 6d, 7a and 7b) Magnetic Survey
The magnetic survey delineated three distinct magnetic domains. Domain 1414
is characterized by a low signature of approximately 200 gammas above base level.
Domain M24 is characterized by a medium signature of approximately 1000 gammas
above base level. Domain M34 is characterized by a high signature of approximately
2000 gammas above base level.
Domain M14 is interpreted to possibly represent east to northeasterly
trending sills of felsic pyroclastic rocks. Domain M24 is interpreted to possibly
represent easterly trending mafic volcanic sills. Domain M34 covers most of the
grid and is interpreted to possibly represent mafic to ultramafic units.
One fault trending in a 110 degree azimuth is interpreted,
Induced Polarization Survey
The short survey failed to delineate any significant anomaly.
Grid 5 (Figures 8a, 8b, Bc, 8d and Se)
I Magnetic Survey
- The magnetic survey delineated three distinct magnetic domains. Domain M15
is characterized by a medium and quiet signature of approximately 1200 gammas
above base level. Domain M25 is characterized by a medium signature of
approximately 1400 gammas above base level. Domain M35 is characterized by a
high signature of approximately 2000 gammas above base level.

Domain M15 is interpreted to possibly represent mafic volcanic units. Domain
M25 is interpreted to possibly represent a gradation between mafic to ultramafic
units. Domain M35 is interpreted to possibly represent ultramafic units.
HLEM Survey
The electromagnetic survey delineated a very weak conductor denoted AB
AS which extends from station 15+OOS on line 10+OOE to station 14+OOS on line
12+OOE. This weak anomaly is associated with magnetic domain M35 and is
interpreted to possibly represent weak sulfide mineralization within the ultramafic
units. Due to the weakness of the conductor, it can also be interpreted to possibly
represent a conductive overburden response,
Grid 6 (Figures Ha, Vb, Ve, 9d and He) Magnetic Survey
The magnetic survey did not delineate any specific magnetic domain other
than a general transition from a medium magnetic signature of approximately 1400
gammas above base level in the southeast corner of the grid to a high magnetic
signature of approximately 3000 gammas above base level in the northwest corner
of the grid. This transition is interpreted to possibly represent a gradation
between mafic volcanic units in the southeast to ultramafic units in the .northwest.
An easterly trending fault is interpreted at approximately station 14+50S, The very
high values of approximately 7000 gammas above base /eve// observed in the
northwest corner of the grid, should be dismissed as they represent cultural
effects.

HLEM Survey
The electromagnetic survey delineated a very weak conductor denoted A6-
A6 which extends from station 12+25S on line 21+OOE to station 13+OOS on line
23+OOE. This weak anomaly is interpreted to possibly represent weak sulfide
mineralization within the mafic to ultramafic units. Due to the weakness of the
conductor, it can also be interpreted to possibly represent a conductive
overburden response. The conductors delineated by the airborne survey (OGS,
1984) were not detected .during this survey.
CONCLUSIONS AND RECOMMENDATIONS
Grid l
The combined magnetic and electromagnetic surveys delineated two conductor
axes within the un-named calc-alkaline Group. These conductors are weak but are
nonetheless coincident with airborne INPUT EM anomalies, therefore further work
should be considered for this grid. A follow-up induced polarization survey is
recommended in order to investigate the extent, nature and alteration Of the
conductors.
Grid 2
The combined magnetic and short induced polarization surveys delineated a
weak chargeability anomaly at an interpreted mafic/felsic contact. This anomaly,
despite its weakness does merit further investigation. Follow-up horizontal loop
electromagnetic and/or induced polarization surveys should be conducted on the
entire grid in order to investigate the possibility of other conductors. Diamond
drilling would follow establishment of more promising targets.

Grid 4
The combined magnetic and short induced polarization surveys did not
delineate any conductors of interest. However, the coverage of the IP survey was
very limited and should not be taken as an indication of lack of conductors.
Therefore follow-up horizontal loop electromagnetic and/or induced polarization
surveys are recommended in order to investigate the presence of conductors.
Diamond drilling would follow establishment of more promising targets,
Grid 5
The combined magnetic and electromagnetic surveys delineated a very weak
conductor within interpreted ultramafic units. A limited follow-up induced
polarization survey covering the conductor axis is recommended in order to
investigate its nature and extent.
Grid 6
The combined magnetic and electromagnetic surveys delineated a very weak
conductor within interpreted mafic to ultramafic units. A limited follow-up induced
polarization survey covering the conductor axis is recommended in order to
investigate its nature and extent.

Function
The TSQ-3 is a multi-frequency, square wave transmitter suitable for Induced polarization and resistivity measurements In either the time or frequency domain. The unit is powered by a separate motor- generator.
The favourable power/weight ratio and compact design of this system make it portable and highly versatile for use with a wide variety of electrode arrays. The medium range power rating Is sufficient for use under most geophysical condi tions. ,jjThe TSQ-3 has been designed primarily for use with the Sclntrex Time Domain and Frequency Domain Receivers, for combined induced polarization and resis tivity measurements, although it is compat ible with most standard time domain and frequency domain receivers. It is also compatible with the Scintrex Commutated DC Resistivity Receivers for resistivity surveying. The TSQ-3 may also be used as a very low frequency electromagnetic transmitter.
Basically the transmitter functions as follows. The motor turns the generator (alternator) which produces 800 Hz, three phase, 230 V AC. This energy is trans formed upwards according to a front panel voltage setting by a large transformer housed in the TSQ-3. The resulting AC Is then rectified In a rectifier bridge. Commutator switches then control the DC voltage output according to the wave form and frequency selected. Excellent output current stability is ensured by a unique, highly efficient technique based on control of the phase angle of the three phase input power.
