SUMMARY
During the summer of 1981 extensive geophysical and geochemical
programs were carried out on the Late Claim near Merritt
British Columbia An east west grid of 16 lines was established
on the property and magnetic and VLF EM readings taken these
were subsequently plotted and contoured An induced polarization
survey was carried out along every second line and plans pre
pared showing chargeability resistivity and self potential
Soil samples were collected at 25 m intervals along all the
survey lines and tested for copper lead zinc and silver
CONCLUSIONS
Lack of outcrop is a hindexance to both the use of geology
and geochemistry as prospecting tools on this property The
soil geochemistry anomalies revealed are consequently small
with the possible exception of copper and scattered The
magnetic survey revealed one area of steep field gradients
typical of underlying volcanic rocks with magnetite content
It is conceivable that the magnetic highs represent more
mineralized regions and the lows may be caused by alteration
however it is not justifiable to recommend drilling targets
on the magnetic data alone unless there are some coincident

anomalies from other surveys Similarly the VLF EM anomalies
although showing up some strong structural trends did not
correspond to other features
In their report Kallock and Goldsmith state No further
exploration of the property is recommended unless strongly
anomalous zones are detected with recent geochemical and geo
physical surveys It is considered that strong anomalies
have not been revealed however if further exploration is
to be carried out it is recommended that drilling be used
to investigate the IP anomaly on line S OON anomaly d
Trenching could be useful in revealing the cause of the VLF
EM anomalies Further geophysics on the claim should not be
employed unless positive results are obtained from the drilling
of the IP feature

INTRODUCTION
This report discusses the theory instrumentation field pro
cedure and results of magnetic VLF EM induced polarizationIP and soil geochemistry surveys carried out over the Late
Claim near Merritt British Columbia The field work was com
pleted in various phases within the period May 12th to October
20th 1981
Outcropping Triassic volcanics on the claim contain patches of
disseminated chalcopyrite and chalcocite the aim of the geo
chemical and geophysical work was to detect surface and depth
expressions respecti vely of any significant base metal
mineralization on the property The use of geophysics and
geochemistry was recommended by Kelly 1980 in his geological
report on the property

PHYSIOGRAPHY
The claim lies on the Thompson Plateau just to the east of
the Cascade Mountains part of the Coast Mountains of the
Canadian Cordillera Total elevation on the property which
is mostly covered by coniferous forest is about 150 m from
1 350 to 1 500 m a s l Thumb Lake which lies partly vlithin
the claim is at an elevation of approximately 1 357 m
GEOLOGY
Although the property is mostly covered by glacial depositsor the waters of Thumb Lake the underlying rock type is
believed to be Upper Triassic volcanic flows and breccias
of the Nicola Group This rock unit in some areas is host
to economic ore deposits copper in particular usually in
association with granodiorite intrusives
vicinity of
Late Claim
In his summary of previous exploration in the
the claims Kelly 1980 hypothesized that the
lay on the eastern limb of a major north trendingand that Thumb Lake marked a WNW trending shear
may have served as a conduit for mineralizing
emanating from granodiorite intrusions to the east
gave rise to metallogenic zoning away from Thumb

Kallock and Goldsmith 1981 found neither contradictory nor

GEOPHYSICAL SURVEY
Instrumentation and Theory
al Magnetic Survey
The magnetic survey was carried out with a model MP 2 proton
precession magnetometer manufactured by Scintrex Limited
of Concord Ontario This instrument reads out directly in
gammas to an accuracy of 1 gamma over a range of 20 000
100 0006 The operating temperature range is 350 to 500
C and its gradient tolerance is up to 5 000j per meter
Only two commonly occurring minerals are strongly magnetic
magnetite and pyrrhotite magnetic surveys are therefore used
to detect the presence of these minerals in varying concen
trations Magnetics is also useful as a reconnaissance tool
for mapping geologic lithology and structure since different
rock types have different background amounts of magnetiteand or pyrrhotite

within it which in turn induces

is measured by the VLF EM receiver
a secondary magnetic field
It is this distortion that
Most EM instruments employ frequencies ranging from a few
hundred to a few thousand Hertz The VLF EM method uses a
frequency range from 16 to 24 KHz and is therefore more sen
sitive to bodies of lower conductivity VLF E l anomalies are
therefore often caused by one or more of the following electro
lyte filled fault or shear zones clay beds porous horizons
carbonaceous sediments e g graphitic relatively low con
ductivity sulphide bodies and lithological contacts The precise
cause of an anomaly is consequently difficult to determine
and VLF EM surveys preferable should not be interpreted without
a good geological knowledge of the property and or the assist
ance of other geopnysical and geochemical surveys
A survey line crossing a buried conductor will record dip
angle values that are negative upward dipping before the
conductor and positive after it as the magnetic component
of the field is deflected up over the body The inflection
point zero crossing on the profile should lie directly over
the causative body
c Induced Polarization Survey
The induced polarization transmitter was a Phoenix Instruments
model IPT 1 powered by a MG 2 60 Briggs Stratton generatorThe transmitter current varied from 0 75 to 2 2A The receiver

The theory of the induced polarization effect is as follows
When a voltage is applied to the ground electric current
flows mainly in the electrolyte filled capillaries in the
rock If the capillaries also contain certain mineral particlesthat transport current by electrons most sulphides some
oxides and graphi te then the ionic charges build up at the
particle electrolyte interface positive ones where the current
enters the particle and negative ones where it leaves This
accumulation of charge creates a voltage that tends to oppose
the current flow across the interface When the current is
switched off the created voltage slowly decreases as the
accumulated ions diffuse back into the electrolyte This type
of induced polarization phenomenon is known as electrode polarization
A similar effect occurs if clay particles are pr sent in the
conducting medium Charged clay particles attract oppositely
charged ions from the surrounding electrolyte when the current
stops the ions slowly diffuse back to their equilibruim state
This process is known as membrane polar ization and gives rise
to induced polarization effects even in the absense of metallic
type conductors

In the process of carrying out an IP survey two other sets
of readings are taken these are resistivity and self potentialliSP The resistivity is a measure of how well the groundconducts electricity and depends mainly on saturation and
the ionic and clay particle content of the pore waters

DThe self potential effect is believed to be caused by the
vertical gradient in Eh oxidation potential usually presentin the ground Any strong conductor e g metallic sulphidesor graphite especially if it intersects the water table
will provide a medium for electron transfer from deeper layersto the surface The current circuit is completed by ionic
conduction through pore water surrounding the conductor The
surface manifestation of this phenomenon is a negative potentialabove the conductor this is generally of the order 100 700

along the 16 east west lines 100 m apart The diurnal variation
was monitored in the field by the closed loop method to enable
the variation to be removed from the raw data prior to plotting
A statistical analysis of the magnetic readings was carried
out by grouping the readings into 100 intervals then plottinga cumulative frequency graph The resulting distribution
was used to choose the threshold values for defining magnetichigh and magnetic low areas on the contour plan
b VLF EM
Dip angle readings were taken at 25 m intervals along the
survey lines
To permit easy contouring a numerical filter the Fraser
filter was then applied to the resul ts This is a 4 pointdifference operator that reduces the inherent high frequencynoise in the data and phase shifts the readings such that
a zero crossing becomes a peak i e a high positive value
Anomaly flanks become negative values when filtered and
these are therefore ignored when contouring
c Induced Polarization
The pole dipole electrical configuration was used for the
work In this array one of the current electrodes is deployeda long distance from the other three electrodes so that it
has a negligible effect on the voltage recorded at the potentialelectrodes For this survey the fixed current electrode was
located at the western end of each line
The two potential electrodes were kept 50 m apart and readings
taken at 50 m intervals along every second survey line with

The chargeability values are read directly from the instrument
and no data processing is therefore required prior to plotting
The resistivity values are derived from current and voltage
readings taken in the field These values are combined wi th
the geometrical factor appropriate for the pole dipole array
to co pute the apparent resistivities The self potential
readings are obtained directly from the instrument The positiveterminal was connected to the eastern potential pot so a
positive reading represents an increase in potential from
west to east
The geophysical data has been presented in two forms The
chargeability and resistivity results for n 2 are shown
in plan form on Sheets 3 and 4 with the values being plotted
half way between the mobile current electrode and the nearer
potential pot The self potential gradient is plotted at the
mid point of the two potential electrodes Sheet 6 An alter
native presentation of multi level IP and resistivity results
is the pseudo section where the figures are plotted at the
intersection of lines drawn from a horizontal datum at 450
from the current electrode and the nearer potential electrode
The IP values are plotted belol the line and the resistivity
values as a mirror image above the line Sheet 5

The most notable feature of the magnetic contour plan is the
area of intense activity in the south west corner of the
property with north south trending high and low anomalies

underlying rock type in this area is augite andesite Elsewhere

The plan of apparent resistivity for n 2 Sheet 4 also
shows how the lowest resistivity areas tend to be in the west
of the property away from the higher IP readings The
variations in resistivity are likely to reflect small changesin moisture content and little can be concluded about the

it is more suitable for detecting massive ore bodies There
fore any anomalies e g on lines 7 00N and 9 00N just north
of Thumb Lake are unlikely to be significant but should
nevertheless be considered in the context of the other survey
results
GEOCHEMICAL SURVEY
Survey Procedure
The soil samples were taken at 2S meter intervals along the
geophysical survey lines The samples were picked up with
a D handled shovel at about a 1S centimeter depth The horizon
sampled was B except where it could not be obtained then
horizon C was sampled Samples were placed in brown wet strengthpaper bags marked with grid coordinates
Laboratory Testing Procedure
All samples were tested by Acme Analytical Laboratories Ltd
of Burnaby B C The sample is first thoroughly dried and
then sifted through a 80 mesh screen A measured amount of
the sifted material is then put into a test tube with sub
sequent measured additions of aqua regia This mixture is
next heated for a certain length of time The parts per million
ppm copper silver lead and zinc is then measured by atomic
absorption
Treatment of Data
A statistical analysis of the copper lead and zinc values
was used to find the background sub anomalous and anomalous
levels of each distribution If the readings approximate a

normal distribution the background is taken to be the 507
level the sub anomalous threshold value is the 16 level
one standard deviation and the anomalous threshold is the
2 1 2 level two standard deviations The sub anomalous
threshold is a term used to denote the minimum value that
although not considered anomalous may still be importantas an indicator of mineralization
Most of the silver values were 0 1 ppm with only a few higherreadings A statistical analysis was therefore not possibleand the sub anomalous and anomalous values were determined
by eyeballing
Results
Copper
The statistical analysis of the copper values showed an
approximate normal distribution but with some skew towards
higher values The background mean level was found to be
18 ppm the sub anomalous threshold 25 ppm and the anomalous
threshold 33 ppm The results were contoured for values above
25 ppm using a logarithmic contour interval see Sheet 7

It will be seen that the cross correlation between geophysicsand geochemistry is not strong There are only a few small
copper anomalies in the magnetically active area to the west
of Thumb Lake the VLF EM lineations do not seem to correspondwith geochemical trends and the IP highs do not contain any
particularly strong geochemical anomalies The geochemicalanomalies are generally weak and scattered with no strongcorrelation between themselves
