COLDWATER CR

AFMAG SURVEY

LOCATION AND MEANS OF ACCESS

The Coldwater Creek claims lie 50 kilometers northeast of

Thunder Bay in Dorion Township. Access to the property is from

Ouimet 50 kilometers east of Thunder Bay on Highway 17. The

Innes Lake road leads from Ouimet and reaches the northern claim

boundary after 9.6 kilometers.

FORMER WORK

There is no record of former work on the property. The

claims were staked for the uranium potential of the basal Sibley

sediments. The work undertaken in 1978 included geological

mapping on and between cut lines, geophysics which included radio-

rnetry, VLF and AFMAG, and geochemistry.

AFMAG SURVEY

The AFMAG, Model No. A651 from McPhar Geophysics was used

for an electromagnetic survey utilizing a natural Tield current

source from worId-wide thunder storms. It measures 2 frequencies,

a high of 470 cps and a low of 140 cps. The unit consists of two

parts, the coil assembly and the amplifier-detector. The coil

assembly has two coils perpendicular to each other. The longest

coil is the Signal coil and the short one the Reference coil.

The Reference coil is rotated clockwise until the meter on the

amplifier-detector is nulled and this direction is recorded with

a hand compass as the field direction. The Signal coil is tilled

in the plane of the field to null again and the dip angle is read

from the pendulum clinometer mounted on the coil assembly. This

-l-

' O:

recorded as the tilt angle. This procedure was followed for

each frequency.

Widely-spaced lines were surveyed on each side of the

Coldwater Creek gorge to verify and locate a geologically inter

preted fault which hopefully was mineralized. The AFMAG can

detect a conductor up to two miles distant and steeper dips are

expected as the conductor is approached.

INTERPRETATION AND CONCLUSIONS

The AFMAG survey on the Coldwater Creek claim group was

specifically designed to assist in the geological interpretation

of the Coldwater Creek Canyon. Survey stations were located so as

to provide information on the conductive properties of the lineal

structure which follows the canyon. The AFMAG readings do not

indicate a major conductive zone within the claim group. The

dominant physiographic feature, {Coldwater Creek Canyon) has a

negligible electromagnetic response and there is no conductor

coincident with, or parallel to the canyon.

Minor sub- surf ace conductors are indicated but nothing of

major significance was detected. A minor conductor trending 025 0

crosses the middle part of claim TB467391 and the southeast corner

of claim TB467388. The variation of azimuth directions and dip

angles along the east boundary of claim TB465873 is consistent

with AFMAG response from a flat intrusive-sedimentary interface

or intercalated sandstones arid siltstones of a flat-lying sedi

mentary sequence, both of which are present in the survey area.

Indefinite nulls on low frequency confirm the absence of

strong conductors. Azimuth and dip angle readings were taken at

-2-

fa*v (X s

survey station (four readings per station). Because the low

frequency readings were generally vague and unreliable, only the

high frequency readings are plotted on the accompanying survey plan.

RADON SURVEY





Innes Lake gravel road leads north from Ouimet and reaches the

northern claim boundary after 9.6 kilometers.

FORMER WORK

There is no record of former work on the property. In

addition to this radon survey, geological mapping, AFMAG sectioning,

VLF survey, geochemical survey and scintillometer prospecting

were also performed.

RADON SURVEY

The radon survey was initiated to find anomalous radon gas

concentrations in the Sibley and trace them to source. To test

for radon in soil, and RD-200 emanometer by E.D.A. Instruments

was used. To test for radon in water, alphameters by Alphanuclear

were used.

The RD-200 uses a suction bulb to pull soil gas into an alpha

counting chamber. The alpha particles fluoresce the treated walls

of the chamber and the photons are counted and accumulated in three

sequential one minute periods. Alpha particles in the soil gas

may be generated from either radon (uranium daughter) or thoron

(thorium daughter). Radon has a half life of 3.96 days and thoron

a half life of less than a minute. Consequently a low ratio of

third minute reading to first signifies principally a thorium source

l

father than uranium, whereas a ratio close to one indicates

uranium. High count rates of course may be significant. Inter

pretation is required based on geology, soil conditions and

background.

The alphameters count alpha photons over a longer period and

considerable interpretation is required because of the many

influencing factors. Radon and thoron are not differentiated in

the count.

During the soil program 86 stations were read with the

highest radon rate only 85 alpha counts per minute. Ratios of

third minute reading to first were low. Soil gas was pumped from

a stoppered hole made in the soil with a steel bar. The holes were

about 18 inches deep by one inch in diameter. Wet areas and areas

of shallow overburden are not sampled.

Twelve water sampling stations were established. The

alphameters were planted in water to a depth of about two inches

and secured to a wooden stake with a metal clamp. The values range

from 10 to 1891 counts per hour with four stations having rates

above 200 cph which might be considered anomalous. Two stations

beyond the claims actually measure runoff from claim TB465873.

To verify the radon anomalies, water and silt samples were

collected. The water samples were strained into plastic bottles

while silt samples were scooped by hand into zip-lock bags and

shipped to X-Ray Assay Laboratories Limited, Don Mills, Ontario

for uranium analyses.

INTERPRETATION AND CONCLUSIONS

The first minute soil gas readings have been plotted and

profiled. There are no anomalous readings in the area of lower

Sibley sediments in the valley of Coldwater Creek where fault

structures probably occur. Reliable third to first minute ratios

are also plotted and all but two of these indicate a thoron source

rather than radon. In the case of the high ratio, the first

minute count is background.

It is concluded that there is no significant uranium minerali

zation present in the Sibley sediments of the northeast claims.

In the Alphameter survey, there were four high, possibly

anomalous readings. In the total readings taken in the areas,

those above two standard deviations from the mean (200 cpm) were

tentatively considered anomalous. However, these four were spring

related and our accumulative data from all Alphameter surveys indi

cates that spring samples must be treated as a separate population.

The high alpha counts are consequently not significant in themselves,

Water and silt samples failed to substantiate the significance of

the high Alphameter readings and it is concluded that the radon

work has not disclosed uranium mineralization on the claims.

GEOLOGICAL REPORT





Innes Lake gravel road leads north from Ouimet and reaches the

northern claim boundary after 9.6 kilometers.

GEOLOGY

Detailed geological mapping showed the area to be underlain

by Archean metasediments which are in turn overlain by the Sibley

Group.

Archean

Metasediments of the Archean basement were observed in two\

locations in the western part of the property. The metasediments

are steeply-dipping, fine-grained siltstones with purplish to black

siliceous argillite partings about l millimeter thick. Bedding

strikes at 080 0 and dips 85 0 to 90 0 to the north. The metasediments

are weakly magnetic. Radioactivity monitored over the outcrops was

40 cps with a BGS-1S Scintillometer {one inch crystal).

Sibley

Sibley Group sediments unconformably overlie the Archean

metasediments. A basal Sibley conglomerate at the Archean exposure

contains numerous angular cobbles of siltstone in a sandy matrix.

Clasts appear to be derived from the Archean metasediments. The

exposed thickness of the conglomerate is 2 meters. Radioactivity

of 40 cps was monitored over the outcrops.

-l-

ti/Ja/. CSlofor&on/ d; S&A&

Red siltstones are the most common rock type in the Sibley

Group. The siltstones contain buff-coloured concretions from

l to 10 cms in diameter. Bedding ranges in thickness from about

10 centimeters to 7.5 meters in the case of the second conglomerate

(below), and dips less than 10 0 to the east.

Mudcracks were observed in several locations indicating

shallow water deposition.

Limestone occurs as interbeds varying in thickness from

2 to 60 cms.

A second type of basal Sibley conglomerate was observed in

the creek valley to the east of the Archean exposure. The conglo

merate contains subrounded to rounded clasts of red siltstone,

granite cobbles and tabular shale fragments. The matrix is fine-

to medium-grained sand with a calcareous cement.V

Diabase sheets of Late Precambrian Age intrude the Sibley

Group sediments and form a scarp on each side of the creek.

Talus slopes of angular diabase blocks cover most of the diabase-

Sibley contact.

Overburden

Overburden is very shallow over the property. On the plateau

areas underlain by diabase, forest cover is fairly heavy over

shallow overburden with abundant outcrop. The only marshy areas

are restricted to the edges of the line of small ponds south of

Coldwater Creek.

The valley sides of the creek are covered with diabase talus

and the creek bottom itself has numerous erratic granite boulders.

The low areas of Sibley in the northeast claims is underlain by

2

&f'n' (v SyMoci'ftfo

^preddish Sibley rubble and covered with denser forest and under

growth.

Structure

A fault zone along the creek is the most important structural

feature of the property. The exact movement on the fault is not

known but a minimum apparent vertical movement of 35 meters was

determined. The south side of the creek has been uplifted in

respect to the north, thus exposing what is interpreted as basal

conglomerate of the Sibley in claim TB465875. The Archean

exposures with basal Sibley conglomerate in claim TB467389

probably occur in a horst.

A second structure trending 100 0 was defined during a VLF

survey and is coincident with three ponds on the property. No

evidence of faulting was observed in outcrops.i

No evidence of veining or mineralization was found.

OTHER WORK

No former work is known on the claims and no evidence of

pitting or trenching was found.

In addition to line cutting and the geological mapping, radio

metric prospecting, AFMAG sections, VLF survey, radon survey and

geochemcial survey were performed.
