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:

(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.

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.

.

.


-3-

.

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.

.


.

-4-

.

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.


-2-

• '{ 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.

.

S


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.
