SUMMARY

Jamie Frontier Resources Inc. optioned the property from Mr. G. L. Mealey

and partners in May 1986. It consists of 39 contiguous mining claims, staked in the west

side of Sandra Township in the Thunder Bay Mining Divison. It is located within the

Beardmore-Geraldton Greenstone Belt, in the vicinity of the Town of Beardmore, about 7

miles west of the currently discovered "Metalore" deposit.

The claim group shows geological similarities with the Metalore find both in

lithology and in structural geology.

Oust west of the property, in Dorothea Township, gold was discovered in

quartz veins during the 1930's. The host rocks of this early occurrence continue over the

township and property boundary unto the damie claims. '

It was concluded that the property has a good potential to host gold

mineralization and therefore merits an exploration program consisting of airborne

surveys, ground follo-v-up and diamond drilling of approximately 5,000 feet. The cost of

such an undertaking was estimated to be Sl07,620 for the first phase and $167,200 for

the second. An approximate total of $275,000.

INTRODUCTION

The following report has been compiled at the request of Mr. H. Vance White

the President of Jamie Frontie Resources Inc., with its Head Office at Suite 1201, 121

Richmond Street West, Toronto, Ontario. The claims were acquired under the terms of a

three year working option from Mr. G. L. Mealey and parterns, all from the Thunder Bay

area.

The author, who is familiar with the Beardmore-Geraldton area, visisted the

property in June of 1986 accompanied by Mr. G. L. Mealey.

The report is based on the author's extensive research of published material

relating to the area, the files of the Ministry of Northern Development and Mines

(Thunder Bay), verbal communications with the geological staff of the Ministry and

others. Also the author's 23 years of experience as a mining geologist, his familiarity

- 2-

with the area and a visit to the property.

THE PROPERTY, ITS LOCATION AND ACCESS

The Sandra Township property of 3amie Frontier Resources Inc. was optioned

from Mr. Mealey and partners on the 5th of May, 1986. The property was staked by Mr.

Mcaley and partners and it was acquired by Jamie after a release of information about a

gold discovery by Metalore Resources, a company which has been exploring for several

years in and around Irwin Township in the vicinity of Beardmore.

The claims are located in the southwest quarter of Sandra Township in the

Mining Division of Thunder Bay, Geraldton-Nipigon Mining District.

*

The claim group occupies a more or less rectangular shape between the west

shore of the Namewaminekan River and the west boundary of Sandra Township.

The claims are numbered as follows:

HISTORY

I

Gold was first discovered in the Beardmore-Geraldton area in 1925 at the

Eieardmore Mine property. The first production from the area came from the Northern

Empire Mine which commenced production in 1934. Gold was produced in the Beardmore

area until 1968. Considerable exploration activity has been noted from the early years,

however, very little information can be found from those times. Exploration for gold has

been on the decline since the 19^0's due to depressed gold price. In the 1950's the

interest shifted to base metal exploration from these times on sporadic exploration

focusing mostly on base metals has been reported lasting to the late seventies without

any considerable success this work was mainly local and of moderate dimensions. With

the increase in the price of gold starting in the late seventies the Beardmore-Geraldton

group became moderately active until very recently when a staking rush of major

proportions took place.

According to the reports of the Northern Miner, close to 6,000 claims were

staked in approximately 5-6 months from the time the releases from the Metalore

discovery became public knowledge.

Very little information regarding the history of Sandra Township is available.

Two occurrences of gold are mentioned, both were discovered and worked in 1936. The

most significant work is filed in the neighbouring Dorothea Township and it spilled over

to the east to Sandra Township. The Amorada Prospect was worked "probably" by

various interests prior to 1958 when Nortoba Mines Ltd. conducted geophysical surveys

and some diamond drilling. Later in 1965 Candore Explorations Limited had explored a

molybdenite showing with stripping, trenching and diamond drilling. Gold was not a

priority at this time and the drill results from the molybdenite showing were not as good

as anticipated therefore Candore withdrew from the option.

The information found regarding the gold occurrence is very limited.

Diamond drilling indicated the presence of a gold-bearing vein which averaged 1.1 ounces

of gold per ton, but had only a limited length (25. 0') is reported by Ministry of Natural

l

0 ffi

Resources in 1971. Diamond drill logs on files are mostly without any assay information.

The few logs which have this informtjbn show only very few samples.

REGIONAL GEOLOGY

The Beardmore-Geraldton area lies within an east trending folded sequence

of early Precambrian rocks composed of metavolcanics and metasedimentary units

streching east of Lake Nipigon to the vicinity of Klotz Lake.

In summary a unit of fine grained metasedimentary rocks bound on the south

on mafic to intermediate volcanics. These appear to be unconformably overlain by a

coarser metasedimentary unit in the Geraldton area. Both metasedimentary units thin to

the north. In the Beardmore area they are overlain by mafic to intermediate unit.t

Further north, up section, in the Paint Lake area of felsic pyroclastic rocks

interfinger with coarse clastic metasediments. The metasedimentary and metavolcanic

series are intruded by felsic batholites and lenticular mafic intrusions. Late

Precambrian diabase dikes and sills are abundant on the western part of the belt.

Folding has been reported extensively on the Geraldton area and to a lesser

degree at Beardmore, fold axisis are trending east-west. Regional faults show the same

trend and mark changes in the lithology. Subsidiary faults occur and are striking

northeast.

Several ideas have been put forward just recently regarding the genesis of the

Beardmore-Geraldton Greenston Belt. Some of these current thoughts suggests that the

coarse conglomerates found here are derived from gravel alluvial fans from areas of

uplift. Others propose that the volcanics represent fragments of a plate which was

squeezed under and into a sedimentary section.

The author has been informed about work currently being done at Brock

Univesity regarding the area, which research eventually will benefit further exploration.

PROPERTY GEOLOGY

The most distinct geological feature in Sandra Township is a wide diabase

dike (2 to 3 miles in width) which diagonally cuts across the township and is represented

by several outcrops. It has been mapped both north and south of the property.

The north side of the 3amie claims are underlain by mafic amygdaloidal lavas

south of which a series of undifferentiated felsic and intermediate volcanics both rock

types, are represented by several outcrops. Further south near to the property boundary

outcrops of polymictic conglomerates were found. Gold showings in Dorothea Township

are just west of the township and property boundaries. The Paint Lake Fault is shown to

come up against the diabase intrusion on the east. If it would extend past the diabase it

appears that the 3amie property would occupy most of its path.

ECONOMIC GEOLOGY

According to recently published reports by the Ontario Geological Survey the

Beardmore-Geraldton camp has produced in excess of 4.1 million ounces of gold between

1934 and 1968. Nineteen prospects and producers were named, in this report, three of

which were below the thousand ounces output. The most gold came from the MacLeod-

Cockshutt Mine. It was located in the Geraldton side of the belt, in Ashmore Township

about 40 miles to the east of 3amie claims. Here 1,366,404 ounces of gold were

produced between 1938 and 1968, most of which came from a zone of numerous quartz

veins in metavolcanic rocks near a feldspar porphyry intrusion. The overall grade was

0.15 ounces of gold per ton milled.

The second largest and important, also the highest grade producer was Leitch

Gold Mines Limited which was active between 1936 and 1968. The mine was in Eva

Township about 4 miles southwest of the 3amie property. Gold recovery here averaged

0.92 ounces gold per ton milled and the total output of the mine was reported as 847,690

ounces. The gold occurred in greywackes with interbeds of iron formation and

conglomerate intruded by diorite and diabase dikes. It was associated with quartz veins

which were mainly found within the greywackes.

*

The newest discovery, which has sparked the current staking rush, was made

by Metalore Resources Ltd. This property lies in the neighbouring Irwin Township to the

m

Bd

tBJ

Hm

-6-

east of the Jamie claims with approximately seven miles. According to releases by

Metalore, gold was found in economic grades at depth under an old surface showing. This

occurrence was investigated by others in the past. Metalore conducted deeper

exploration drilling and found the downward extension of the deposit. It has been said

that the deepest intersection is about at 1,500 feet vertical and the deposit is still open

at depth. This significant discovery has again focused toe attention to the Beardmore-

Geraldton area and is in part responsible for renewed exploration activity.

CONCLUSIONS

After compiling the data and examining the property the author has reached

the conclusion, that the Jamie Frontier prospect in Sandra Township has a good potential

to host gold mineralization and therefore it is worthy of an exploration program to

investigate this potential. The above statement is based on the following factors.

HJj (a) Geological similarities between the Metalore deposit and the Jamie

properties such as the similar lithologies with the deposit like the.

occurrence of polymictic conglomerates in contact with volcanics.

(b) The property lies in an area where gold deposits were mined in the past.

(c) Gold has been reported from a short distance from the property where

the same rocks known from the 3amie property also occur.

An exploration program consisting of two phases is therefore recommended.

RECOMMENDATIONS

Since it has been demonstrated that certain structural features, such as

contacts and faults have a definite geophysical expression which can be observed by

utilizing airborne geophysical surveys, it is suggested that such work be completed prior

to any ground work. The airborne survey should include both magnetic and VLF systems

which have been found the most successful in locating contacts and structural features.

To follow up on the airborne surveys it is suggested that a line grid allowing

for sufficient detail work be established. Line separation of 300 feet and picket spacing

of 20 feet is proposed.

- 7

We are also recommending that geological mapping be completed in

conjunction of geochemical sampling. To conclude the surface work we suggest a VLF

and a magnetic survey be conducted over the grid area.

As a second phase it is suggested that a diamond drilling program be

undertaken approximately 5,000 feet of drilling is required to test the selected targets

found by the surface work.

The third phase of exploration would commence only if the previous two have

shown definite success and warrant follow up.

1. INTRODUCTION aa

This report describes the specifications and results of a f geophysical survey carried out for Mid North Engineering Services Ltd. of 1201-121 Richmond Street West, Toronto Ontario M5H 2K7 by Terraquest Ltd., 905 - 121 Richmond St. W., Toronto, Canada. The field work was performed on August 31, 1986 and the data processing, interpretation and reporting from September l to October 27, 1986. K

aThe purpose of a survey of this type is two-fold. One is to

prospect directly for anomalously conductive and magnetic areas in the earth's crust which may be caused by, or at least related to, mineral deposits. A second is to use the magnetic and conductivity patterns derived from the survey results to assist in mapping geology, and to indicate the presence of faults, shear zones, folding, alteration ~ zones and other structures potentially favourable to the presence of gold and base-metal concentration. To achieve this purpose the survey area was systematically traversed by an aircraft carrying geophysical instruments along parallel flight lines spaced at even intervals, 100 metres above the terrain surface, and aligned so as to intersect the regional geology in a way to provide the optimum contour patterns of geophysical data.

2. THE PROPERTY

The property is located in Sandra township, in the Thunder Bay Mining Division of Ontario about 12 kilometres north of the settlement of Beardmore. The claims lie in the southwest quadrant of the township and are readily accessible from logging roads.

The survey area is underlain by east-northeast trending mafic to felsic metavolcanics and minor metasediments and a dioritic sill. Outcrops of ironstone and vein-type gold, silver and sulphide mineralization occur to the west beyond the property.

Regionally, the area is structurally complex with faults trending to the east, east-northeast, northeast, north and northwest.

4. SURVEY SPECIFICATIONS

4.1 Instruments

The survey was carried out using a Cessna 182 aircraft, registration C-FAKK, which carries a magnetometer and a VLF electromagnetic detector.

The magnetometer is a proton precession type based on the Overhauser effect. The Overhauser effect allows for polarization of a proton rich liquid of the sensor by adding a "free radical" to it and irradiating it by RF magnetic field. Strong precession signals are generated with modest RF power. The sensor element is mounted in an extension of the right wing tip. It's specifications are as follows:

Resolution: 0.5 gammaAccuracy: 0.5 gammaCycle time: 0.5 secondRange: 20,000 - 100,000 gammas in 23 overlapping stepsGradient tolerance: Up to 5000 gammas per metreModel: GSM-9BAManufacturer: GEM Systems Inc., 105 Scarsdale Rd.,

Don Mills, Ontario, MSB 2R5

The VLF-EM unit uses three orthoganol detector coils to measure (a) the total field strength of the time-varying EM field and (b) the phase relationship between the vertical coil and both the "along line" coil (LINE) and the "cross-line" coil {ORTHO). The LINE coil is tuned to a transmitter station that is ideally positioned at right angles to the flight lines, while the ORTHO coil transmitter should be in line with the flight lines. It's specifications are:

Accuracy: l *Reading interval: 1/2 secondModel: TOTEM 2AManufacturer: Herz Industries, Toronto

5. DATA PROCESSING

Flight path recovery was carried out in the field using a videotape viewer to observe the flight path as recorded by the Geocam videocamera system. The flight path recovery was completed daily to enablereflights to be selected where needed for the following day.

The magnetic data was levelled in the standard manner by tyingsurvey lines to the tie lines. The IGRF has not been removed. Thetotal field was contoured by computer using a program provided byDataplotting Services Inc. To do this the final levelled data set isgridded at a grid cell spacing of 1/lOth of an inch at map scale.

The vertical magnetic gradient is computed from the total fielddata using a method of transforming the data set into the frequencydomain, applying a transfer function to calculate the gradient, andthen transforming back into the spatial domain. The method isdescribed by a number of authors including Grant, 1972 and Spector,1968. The computer program for this purpose is provided by Paterson,Grant and Watson Ltd. of Toronto

The VLF data was treated automatically so as to normalize the nonconductive background areas to 100 {total field strength) and zero(quadrature). The algorithms to do this were developed by Terraquestand will be provided to anyone interested by application to thecompany.

All of these dataprocessing calculations and map contouring werecarried out by Dataplotting Services Inc. of Toronto.

magnetic intensity and patterns or "signatures". Where possible these are related to existing geology to provide a geological identity to the units. On a regional scale the total field contour patterns were used in the same way.

Faults and shear zones are interpreted mainly from lateral displacements of otherwise linear magnetic anomalies but also from long narrow "lows". The direction of regional faulting in the general area is taken into account when selecting faults. Folding is usually seen as curved regional patterns. Alteration zones can show up as anomalously quiet areas, often adjacent to strong/ circular anomalies that represent intrusives. Magnetic anomalies that are caused by iron deposits of ore quality are usually obvious owing to their high amplitude, often in tens of thousands of gammas.

VLF anomalies are categorized according to whether the phase response is normal, reverse, or no phase at all. The significance of the differing phase responses is not completely understood although in general reverse phase indicates either overburden as the source or a conductor with considerable depth extent, or both. Normal phase response is theoretically caused by surface conductors with limited depth extent.

Areas showing a smooth response somewhat above background (ie. 110 or so) are likely caused by overburden which is thick enough and conductive enough to saturate at these frequencies. In this case no response from bedrock is seen.

6.2 Interpretation

The total magnetic field has a relief of approximately 510 gammas and shows the general trend of the lithology. The vertical magnetic gradient brings out the minor trends and, in places, shows improved resolution of the major trends. The following notes supplement the accompanying data and interpretation maps which form the major end-product of the survey.

The strong, north trending magnetic anomalies are interpreted to be diabase dykes (Unit 12) crosscutting the stratigraphy. These have been significantly offset by east-west faults. As these dykes are characterized by strong magnetic responses, their magnetically mapped widths may be exaggerated.

The outcrops of mafic to intermediate metavolcanics {Unit 1) and felsic to intermediate metavolcanics (Unit 2) correlate with moderate magnetic responses. Horizons of strong magnetic activity (Units 1m and 2m) may be related to increased concentrations of magnetic minerals (such as magnetite or pyrrhotite) or to more mafic horizons.

Outcrops of clastic metasediments (Unit 4) correlate with weak magnetic responses. The east-west trending anomaly within this geological unit to the south is interpreted to be ironstone (Unit 3) in composition. The variation in magnetic activity along strike may be related to the width, number of individual horizons or the concentration of magnetic minerals. Variation in concentration may in turn be related to facies changes, such as magnetite ironstone to sulphide or carbonate ironstone.

Numerous VLF-EM conductor axes have been identified and evaluated according to the Terraquest classification system {Figure 4). This system correlates the nature and orientation of the conductor axes with stratigraphic, structural and topographic features to obtain an association from which one,or more origins may be selected. Alternate associations are indicated in parentheses.

The interpretation of the VLF-EM data is complicated by the fact that some faults possess similar orientations and topographic features as the stratigraphy. Therefore many of the conductor axes interpreted to possess stratigraphic sources may also, or alternatively/ possess fault related origins. The conductivity of faults may be related to mineralogic (such as gouge, graphite or sulphide) or electrolytic (porosity or overburden) origins. Faults defined by magnetic or VLF-EM data may provide primary structural control for epithermal mineralization.

Those conductor axes that coincide with or parallel the magnetic stratigraphy possess potenial for bedrock, stratabound sources, either as mineralogic or electrolytic origins. These should be followed up on the ground by EM or IP techniques.

7. SUMMARY

An airborne combined magnetic and VLF-EM survey has been done on the property at line intervals of 100 metres. The total field and vertical gradient magnetic data, VLF-EM data and interpretation maps are produced at a scale of 1:10,000.

The magnetic data has been used to modify and update the existing geology and has shown a number of new contacts and faults. A number of VLF-EM conductor axes were found of which some are believed to have potential sulphide origins and have been recommended for additional investigation.
