S INTRODUCTION
The Old Fort River Permit is located on the Alberta-Saskatchewan boundary
immediately northeast of the inferred Athabasca Formation - crystalline Shield
contact. Little data are available regarding the nature of the underlying
basement rocks, thickness of the Athabasca Formation or its composition within
this region.
The Amok Limited "Cluff Lake" uranium deposits are located approximately
23 miles to the northeast. This uranium enrichment took place prior to the
development of the Carswell domal feature and is closely affiliated with the
Athabasca unconformity. The Maurice Point unconformity-related uranium
deposit of Uranerz - S.M.D.C. is located 60 miles north of the property.
On the basis of the Athabasca unconformity being present in the Permit
area at an inferred shallow depth" a detailed surface exploration program
.
was conducted during the 1977 field season. The program consisted of:
Lake sediment & lake water geochemistry
Surface prospecting & ground scintillometry
Radon soil gas determinations
VLF electromagnetic survey
Office compilation of existing data
Aerial photograph examinations (including Landsat imagery)
LOCATION AND ACCESS
The Old Fort River Property is located on the Alberta-Saskatchewan
boundary, approximately 105 miles northeast of Fort McMurray. The area is
presently accessible only by float or ski-equipped aircraft.
The nearest future road access will be to Amok's Cluff Lake deposits,
approximately 10 miles east of the permit.

HISTORY OF EXPLORATION
A review of assessment work filed at the Research Council of Alberta
indicates that the majority of the permit area was previously held under
disposition as Quartz Mineral Exploration Permits No. 93 & 94 by Anco
Exploration Ltd. Both permits were flown by Canadian Aero Surveys Ltd.
in October, 1969. Instrumentation included a Canadian Aero MK III IP/OP
E. M. system (390 Hz), a magnetometer, and an Exploranium spectrometer
(three 6" x 4" crystals.) No electromagnetic or radiometric anomalies
were obtained and there is no record of subsequent ground surveys.
Section 1, Twp. 5, Ri, W4M was previously held by Canada Southern
Petroleum Ltd. as Permit No. 9. A photogeological map and an airborne
scintillometer survey were completed by Geophoto Services Ltd. of Calgary.
No bedrock geological mapping has been conducted in the vicinity of
the property; however, the area has been mapped on a reconnaissance surficial
basis by L. A. Bayrock of the Research Council of Alberta (R.C.A. Map 14,
Surficial Geology, Fort Chipewyan.)
G.S.C. Aeromagnetic coverage is available at scales of 1' = 1 mile and
1" = 4 miles as maps 2844 G (Archer Lake, N.T.S. 74-L-1) and 7159 G (Chipewyan,
N.T.S. 74-L) respectively.
A reconnaissance refraction seismic survey of the Athabasca Basin was
conducted during the period 1962 to 1968 by G. D. Hobson and H. A. McAuley
(G.S.C. Paper 69-18 and Map 69-2). Two seismic stations were located within
the present permit boundaries (c.f. figures 1 to 3 incl.). Depths to
basement were calculated at 108' and 188'.

0 LAND STATUS
A Quartz Mineral Exploration Permit entitled the "Old Fort River Property"
was applied for by Taiga Consultants Ltd. on January 30, 1976, and granted
September 29, 1976. The first anniversary date for renewalws September 29/77.
The permit is more particularly described as follows:
Township 104, Range 1, West of the 4th Meridian
Sections 25, 35 and 36
Township 105, Range 1, West of the 4th Meridian
Sections 1 to 3 incl., Sections 10 to 15 incl., Section 24
.
TOTAL 13 Sections (8,320 acres)
The permit is presently recorded in the name of E. & B. Explorations Ltd.
A land map of the adjacent mineral dispositions is included overpage.
SURFICIAL GEOLOGY
The permit is completely mantled by glaciofluvial deposits. Sinuous,
ribbed or corrugated ice-retreat morraine deposits, kames, eskers, and
crevass fillings give rise to local relief in excess of 150' in the western
and southern portions of the property. These corrugations lie perpendicular
to the direction of the most recent ice advance, which was from the northeast.
Elsewhere on the permit relief is generally less than 75' and is comprised
.,
of gently undulating, drumlinized outwash sand and gravel ridges.

REGIONAL GEOLOGIC SETTING
As previously mentioned, little data are available regarding the nature
of the Athabasca Formation or the underlying crystalline basement rocks in
this region. G.S.C. Map 16-1961 (Geology of the Firebag River Area; L.P.
Tremblay) indicates that the nearest outcrop is an exposure of Athabasca
Formation 8 miles southeast of the Permit. Clastic deposition is interpreted
as being from the south-southeast (c.f. Fig. 6, appendix).
The nearest exposures of Precambrian basement rocks are at Cluff Lake,
Saskatchewan (25 miles northeast of the permit), and along the Maybelle River
in the northeast corner of Twp. 102, R-4, W4M, (20 miles southwest of the
permit).
The Cluff Lake rocks have been mapped in detail and the following summary
is excerpted from the Saskatchewn 1977 Summary of Investigations (C. T. Harper):
The central core of the Carswell Dome appears to be formed by interlayered reddish granitoid gneisses, quartzo-feldspathic and pelitic gneisses. These rocks have undergone repeated folding followed by late cataclastic deformation. Metamorphism reaThing granulite facies conditions in part if not all of the area was followed by retrogression to amphibolite and possibly even greenschist conditions.
The metamorphic rocks have been subdivided by Amok geologists into the following lithologic units (Anon, 1974: Tapaninen, 1975; and Herring, 1976):
I. Pelitic Gneisses:
(a) garnet-cordierite gneiss
(b) garnet-sillimanite gneiss

2. Quartz -feldspathic Gneiss:
(a) fine-grained quartz-feldspar-biotite gneiss
(b) porphyblastic grantoid gneiss
3. Mafic Gneiss:
(a) pyroxene bearing granulite
(b) amphibolite
All these units have intruded by Cluff Breccia dykes."
On the other hand, Precambrian exposures on the Alberta side have only
received the most cursory of examinations. Outcrops along the Maybelle and
Marguerite River have been roughly subdivided into 1.) interbanded, grantoid,
garnetiferous quartz-feldspar-biotite gneiss and 2.) garnetiferous, red and
white granite and pegmatite with minor, bedded quartzite rock (G.S.C. Map 16-
1961).
No direct correlation has - been evidenced between thé'Cluff Lake exposures
and the Maybelle - Marguerite River outcrops. However, both groups have been
included in the Firebag Domain (retrogressed Archean craton) by the Saskatchewan
Mineral Resources Division. It has also been suggested by several writers
that the Firebag Domain is regionally correlatable with the Beaverlodge /
Uranium City crystalline rocks.
Local alteration & metamorphism of the Cluff Lake rocks has been
summarized by C. T. Harper as comprising the following sequence of events:
U • Prograde regional metamorphism to the granulite facies
during the major deformation phase.
2. Retrogressive metamorphism to the upper amphibolite facies
probably related to hydration accompanying emplacement of
pegmatoids.
.
I TAIMA
.
I -6-
3. Retrogression (not defined) associated with mylonitization.
4. Alteration due to weathering of the basement during the
pre-Athabasca erosion period.
5. Pale green to white chloritic and argillic alteration of the
rocks above and below the sub-Athabasca unconformity by low
temperature (200-150°C) hydrothermal activity with associated
uranium mineralization.
6. Alteration (chl.oritic and argillic) associated with the formation
of the Carswell structure
Superimposed are shock metamoprhic effects."
Harper has also interpreted the structure of the Cluff Lake basement
rocks as follows:
Three episodes of deformation are recognized, which on the basis of a single K-Ar date of 1973 m.y. (Herring, 1976), are believed to be of Hudsonian age.
The earliest phase produced the regional foliation, presumably axial planar to first generation folds although no folds of this period have been recognized. The second phase deformed the regional foliation into tight overturned folds but did not produce a new well defined foliation. These structures are dominant in the area and probably control the distribution of rock units. The third phase structures refold the first two producing low amplitude warps and open folds in a general northerly direction, on both a minor (outcrop) and major regional scale. It is believed that cataclastic deformation may have accompanied the third deformation, with tectonic breccias and mylonites forming along the major fold axial surfaces. These zones could provide suitable sites for uranium mineralization.

The regional trend of the foliation has a sweeping S shape from the northwest to the southeast. There is apparent dis-location along two major lineaments, the Carswell-Bridle Lakes lineament and the Cluff Lake lineament, which form part of the radial fault system of the Carswell structure. It is possible that these lineaments represent reactivated mylonitic shear zones of the Hudsonian orogenic period." (1977 Sask. Summ. of Investigations, p. 141).
The most salient point noted above is the possible southwestward extension
of the Cluff Lake lineament through the area of the Old Fort River permit.
This is tentatively suggested by the 1" = 4 mile aeromagnetic compilation
(c.f. figures 4 & 5 this report). There is no identifiable surface
expression of this lineament on the property however, and its existence is
questionable.
To date, no detailed studies of the western margin of the Athabasca
Formation have been published. A reconnaissance seismic survey of the
Athabasca Basin indicates a thickness of less than 500' of sandstone over-
lying the property (a seismic station 3 miles south of the property yeilded
a calculated thichness of 118'. A second station 8 miles northwest of the
permit yielded a calculated thickness of 108' (c.f. Figures 1 to 3).
EXPLORATION RESULTS
LAKE WATER SEDIMENT & WATER GEOCHEMISTRY
A helicopter-supported lake sediment and lake water geochemical sampling
program was conducted on June 7, 1977. A total of 49 lakes were sampled
during this survey and duplicates were collected from two of these sites.
The lake bottom, organic-rich sediment samples were collected with a
1976 model Hornbrook sampler (c.f. photo in appendix). Surface lake water
samples were collected in polyethylene bottles at depths of 6 to 12 at the
same sites.

The sediment samples were analyzed by fluorometric technique by Loring
Laboratories Ltd., Calgary and the water samples were analyzed by fission
track technique by Bondar-Clegg & Company, Ottawa.
The geochemical analysis for uranium in water and U, Cu, Pb, Zn, Ni,
Co, and Mo in lake sediments are included in the appendix. Sample locations
and geochemical results are plotted on enclosed maps A-76-2-3 and A-76-2-4.
A comparison of the duplicate samples,with analysis reported in parts

Sample EB0-11S, collected from a small lake on the eastern property
boundary, returned the single anomalous uranium value (7.4 ppm). The highest
Cu and Pb values (25ppm and 26 ppm respectively) were also obtained from this
sample site. This lake possibly correlates with an east-west trending band
of slightly higher uranium content in lake sediments.
Variations in other metal values display no readily discernable patterns
and little significance can be attributed to the metal distribution at this
time.
The Zn results display the greatest fluctuations in values. The highest
Zn analysis (210 ppm) was obtained from sample EB0-125. This was from a
clay-rich sample which suggests that the Zn values may be related in part to
the clay content of the samples.
In summary, the low geochemical values obtained are consistent with an
area of Athabasca subcrop. Basement lithologies are either not present
within the permit area, or, if present, contain extremely low uranium and
heavy metal values. No anarnalous results warranting investigation were
detected.
PROSPECTING TRAVERSES (Map A-76-2-5)
A four-man field party under the direction of A. Bak, geologist, prospected
the permit area in detail. No outcrops or mineralization of significance
were noted.
Till deposits are composed dominantly of Athabasca sandstone. Sparse
granitic boulders, generally well rounded, were noted throughout the permit area.

Instrumentation used for the prospecting traverses consisted of 3 STRAT
SPP2 scintillometers, 1 Scintrex BGS 1SL scintillometer, and a McPhar TV-1A
differential spectrometer. Background radioactivity was relatively constant
in the order of 20 to 25 counts per second. Numerous granite boulders
yeilded 50 to 75 c.p.s. The highest radioactivity detected was lOOcps in
several well hematized sub-angular to sub-rounded Athabasca sandstone
(quartz arenite) boulders.
VLF ELECTROMAGENTIC SURVEY (Map A-76-2-1)
A chain & compass flagged grid of approximately 27.5 line miles was
established over the majority of the permit. Cross lines, at an irr gular
spacing (generally in the order of 1,500'), were oriented NW-SE.
A VLF electromagnetic survey was conducted utilizing a Geonics EM-16
unit and Seattle, Washington as the transmitter station. Readings were
taken at 100' station intervals.
Five isolated, very weakly conductive responses were obtained.
Tentatively, these have been ascribed to a combination of overburden and
topographic orientation effects. None warrant follow-up at this time.
RADON SOIL GAS DETERMINATIONS (Map A-76-2-2 )
Radon soil-gas measurements were taken at 200' sample intervals over
those portions of the grid not covered by boulder till or muskeg. An E.D.A.
Electronics model RD-200 emanometer was used for the survey.

S Results plotted on map A-76-2-2 are in total counts per minute (radon
plus thoron) for a one minute sample time. Because of the low values
encountered, no attempt was made to calculate net radon counts.
Background varied from 5 to 9 counts per minute. Five readings in excess
of 13 cpm (best value was 19 cpm) were obtained at the west end of lines
153N and 185N. However, these are not considered significant at this
reconnaissance level and may, in fact, be related to varying soil dampness or
weather conditions.
CONCLUSIONS
1.) The lake sediment and lake water geochemical survey, although
indicating a weak east-west trend of higher uranium values, did
not locate any areas warranting detailed investigations.
.
2.) Regional mapping, surface prospecting, and the low geochemical
values obtained suggest that subcrop in the permit area consists
of Athabasca Formation rocks.
3.) The results of both the VLF-EM and the radon soil gas surveys are
inconclusive. A probable considerable thickness of surficial deposits
and Athabasca Formation makes it unlikely that either technique
could delineate unconformity or basement-type targets. However,
this data should be reviewed in conjunction with other exploration
methods applied in the future as subtle anomalies may assist in
priority selection of targets.
The possible presence of the Paleo-Helikian / Athabasca Formation
unconformity at shallow depths (i.e. less than 500') within the permit area
still requires further evaluation. Exploration programs during the past two
years in Saskatchewan have revealed that basement electromagnetic conductors

.
at the unconformity form the principle setting for high-grade uranium
mineralization within the Athabasca Basin. Secondary targets may also be
outlined by high resolution magnetics.
RECOMMENDATIONS
Exploration results from Saskatchewan properties with similar geological
environments, in conjunction with observed surficial conditions present within
the Permit, has shown the need for a different exploration approach than
initially proposed. Surface radon determinations and geochemical analysis
do not appear to have the ability to penetrate thick surficial deposits as
well as an indeterminate thickness of Athabasca Formation. If such geochemical
responses do exist, they form subtle anomalies that in themselves are not
drill targets.
.
During the past two years the value of electromagnetic and magnetic
coverage in locating potential drill targets within the Athabasca margin has
become increasingly evident. The selection of either an airborne or ground
approach is based on a consideration of the costs, comparative depth
capabilities, degree of sensitivity & resolution, environmental impact, and
field season timing.
The following program is herein recommended:
1.) An airborne electromagentic and proton magnetometer survey should
be completed over the permit at 1/8 mile flight-line spacing with
an east-west orientation. At least 6 north-south oriented survey
lines should be undertaken to check for possible cross structures.
The Questor INPUT system is suggested for this program in view of
its proven track record in similar environments, and its competitive
cost.

2.) Electromagnetic conductors, if present, should be detailed by
ground surveys.
3.) Ground delineated conductors should be tested by drilling.
4.) The magnetic survey results may yield secondary targets warranting
ground geophysical coverage and/or drilling.
PROPOSED WORK PROGRAM & BUDGET ESTIMATION - 1978 SEASON
1.) Pre-field and office $ 1,200.00
2.) Airborne electromagnetic and magnetic survey:
140 line miles, est. @ $35.00 per mile 4,900.00

3.) Provision for an as yet undefined ground
geophysical program, estimate of $500.00
per line mile for 15 miles

NOTE: The property may not be at the drill stage until the third year of
the permit, as drill targets may not be outlined until the spring of 1978.
Testing of these targets will probably require a winter program that would
commence in late fall, 1978.

INTRODUCTION:
The initial field evaluation of the permit has been completed.. However,
data compilation and preparation of final reports will not be completed
until the end of October. Final cost of the program will be available
as soon as all invoices are received and processed.
Exploration conducted on the property during the first term of the Permit
consists of:
Lake sediment geochemistry
Lake water geochemistry
Surface prospecting
Surface geological evaluation
Radon soil gas and/or water determinations
VLF -EM test surveys
Office compilation of existing data
Aerial photograph examinations (including Landsat
imagery)
The exploration results from Saskatchewan properties in similar geological
environments, in conjunction with observed surficial conditions present
within the Permit has shown the need for a different exploration approach,
than initially proposed. Surface radon determinations in conjunction with
geochemical analyses do not appear to have the ability to penetrate thick
surficial deposits as well as an indeterminate thickness of Athabasca
Formation. If such geochemical responses do exist they form subtle anomalies
that in themselves are not drill targets.
Within recent months the value of detailed airborne electromagnetic and
magnetic coverage in locating potential drill targets within the Athabasca
margin, has become evident.

.
GENERAL DISCUSSION:
S
The lake water and sediment results are included as a separate preliminary
report. Delays in receiving the laboratory analytical results in
conjunction with an unusually wet field season were responsible for the
late commencement of the field aspects of the program.
The geochemical results did_ any good target areas within the
Permit, for surface exploration to concentrate on.
No bedrock outcrop areas were observed during the geochemical sampling
program. The vast majority of boulders present consist of Athabasca Formation.
The low geochemical values obtained are consistent with an area of Athabasca
subcrop. Basement lithologies are either not present within the Permit
area or if present contain exremely low uranium and other metal values.
Regional mapping data suggests that subcrOD in the permit area consists of
an unknown thickness of Athabasca Formation.
.
A probable considerable thickness of surficial deposits and Athabasca
Formation makes it unlikely that radon methods will Jefintargt areas
which in themselves will warrant further exploration. Subtle anomalies
in conjunction with other methods may help in oriority selection of target
areas.
The possible presence of the Paleo-Helikian Athabasca unconformity at shallow
depths within the permit area still requires further evaluation. Depths
of up to 600 feet are capable to be explored by electromagnetic techniques:
Exploration programs conducted primarily within the Saskatchewan side within
recent months has shown that basement electromagnetic conductors at the
Athabasca unconformity forms the principle setting for high-grade uranium
mineralization within the Athabasca Formation. Secondary targets may also
be outlined by high resolution magnetic coverage.
I I TAIGA CONSULTANTS LTD.
S -2-
Two alternate approaches are available to explore the property,
Electromagnetic and magentic surveys may either be conducted by ground or
by airborne methods. A consideration of the cost involved, depth penetration
available and environmental aspects, suggests that airborne coverage is the
most practical approach. If an airborne survey obtains favorable results,
detailed ground coverage will be required to detail anomalies.
Upon reviewing the available airborne methods the Questor 'INPUT' system
appears to be the best presently available with regard to reliability,
depth penetration and cost. An attempt to obtain "INPUT' coverage of the
Permit during its first year was not possible due to equipment unavailability.
.
.
TAIGA CONSULTANTS LTD.

.
PROGRAM RESULTS:
The lake geochemical results, although indicating a weak east-west
trend of higher uranium values did not locate any areas warranting detailed
surface examination.
The surface prospecting program also did not locate any significant target
areas. The surface examinations did confirm the probable presence of an
unknown thickness of Athabasca Formation on the property. Published regional
data suggests a relatively thin Athabasca cover of less than 1000 feet
and possibly less than 600 feet. The proven importance of the Athabasca
Paleo-Helikian unconformity as the site of high grade uranium deposits
makes it imperative that further effort be expended to locate target areas
within the Permit. In the most part, ore bodies discovered to date are
associated with electromagnetic conductors.
CONCLUSIONS:
I. Surface methods have not located definite target for further exploration.
2. Seismic methods, although potentially useful in determining depths to
Pre-Athabasca basement do not have the ability to directly define drill
targets.
3. Airborne electromagnetic systems have the capability of outlining conductors
to a maximum depth of approximately 600 feet.
4. High resolution magnetic coverage has the potential to outline favorable
areas that may warrant drill evaluation.
.
TAIGA CONSULTANTS LTD.

.
RECOMMENDATIONS:
1. An airborne INPUT' electromagnetic survey, in conjunction with proton
magnetometer coverage should be completed over the Permit at 1/8th
mile spacing on east-west lines. Some north-south lines should
also be completed at the same time.
2. Electromagnetic conductors, if present, should be detailed by ground
surveys.
3. Electromagnetic conductors, detailed by ground surveys should be tested
by drilling.
4. If no electromagnetic conductors are present magnetic results may lead
to drill targets.
5. If no targets are obtained by the geophysical surveys, seismic methods
may be considered.
6. A drilling program should be planned for testing geophysical anomalies.
Dependent upon timing, drill targets may not be ready until the third
year of the Permit.

OLD FORT RIVER PROGRAM
GEOCHEMICAL RESULTS
INTRODUCTION:
A lake water and lake sediment sampling program was conducted on the Old
Fort River Permit on June 7, 1977. Unfortunately, the analytical results
were not received until August.
A total of 49 sites were sampled during the survey. Duplicate samples were
collected from two of these sites. Sediment samples were sent to
Loring Laboratories in Calgary and the water samples and duplicates to
Bondar-Clegg and Company, Ottawa.
SURVEY RESULTS:
S The geochemical analyses for 'U' in water and U, Cu, Pb, Zn, Ni, Co and
Mo in lake sediments' are included within the appendix. Sample locations
and the results for U in waters and U 308 , Pb and Zn in sediments are
plotted on enclosed maps.
A comparison

Except for Zn values, duplicate analysis yielded similar results for all
of the metals.
Sample EBO-11S returned the best 'U' value. This sample was collected
from a small lake on the Alberta-Saskatchewan boundary (property boundary).
The highest Cu and Pb values were also obtained from this sample site.

• '{ This lake possibly correlates with an east-west trending band of higher
I 'U' content in lake sediments.
Variations in other metal values display no readily discernable patterns
and little significance can be attributed to the metal distribution at
this time.
The Zn results display the greatest fluctuations in values. The highest
Zn value (210 ppm) was obtained from sample no. EBO-12S. This was from a
clay-rich sample which suggests that the Zn values in part may be related
to the clay content of the samples.

I. RECOMMENDATIONS
1. The prospecting program should still be conducted on the property, but
possibly for a shorter time interval than initially proposed.
2. Radon degassing of muskeg waters and soil gas profiles should be
conducted across the east-west trending area of higher 'U' values in lake
sediments.
3. An airborne E.M. and magnetometer survey should be conducted over
the property.
4. Airborne results in conjunction with geochemical and surface
prospecting results should enable selection of follow-up targets.
