INTRODUCTION

VLF EM surveying and rock sampling were conducted on the 33

claim TRI-STAR RESOURCES LIMITED, Hemlo gold area property

between August 23-29, 1985. The VLF EM survey was done using a

Geonics EM-16 unit. A total of 102 rock samples were collected

and analysed for gold.

It is the purpose of this report to discuss the findings of

the VLF EM and rock sampling surveys, and correlate this with

previous (magnetometer, IP, and geological) surveys conducted on

the property.

LOCATION AND ACCESS

The Tri-Star claim group is located in the north central

portion of N.T.S. map 42 D/9, straddling the boundary between Pic

and Lecours Townships. The southwestern boundary of the claim

group is located on the north shore of the Black River,

approximately 6.5 km up river from where Highway 17 crosses over

the Black River, or approximately 2.75 km due north of Highway

17.

Access to the property is by boat, 6.5 km up the Black River

approximately 14 km east of the town of Marathon, Ontario.

PROPERTY

The 33 contiguous mining claims included in the Tri-Star

claim group, encompass approximately 1320 acres of mining land.

The claims are registered with the Ministry of Natural Resources,

TOPQOUPHY AND VEGETATION

Terrain in the vicinity of the Tri-Star claim group on the

Black River, varies from flat swamp to rocky bluff, with a

vertical relief of approximately 130 metres. Major hills

including those in the northern and southeastern parts of the

property are underlain by massive plutons. Smaller east-west

trending ridges and swamps are underlain by the metavolcanics and

metasediments. Scattered outcrop comprises approximately J.5% of

the property. Although the overburden cover in the central part

of the property is extensive, it appears to be quite shallow,

except in the immediate proximity of the major creeks.

A thick forest of spruce, birch and poplar covers the

property. Low areas, swamps and creek valleys are thick with

alders.

the property, magnetometer, IP and geological surveys were

conducted (late 1983). It was concluded from these surveys that

the property is underlain by an east-west trending belt of

intermediate to mafic metavolcanic pyroclastics overlain by

metasediments, and that this belt is intruded by two massive

plutons, one to the north and another to the south. Magnetic

data reflected diabase dikes as linear highs, and within the

volcanic members, isolated magnetic highs occur within certain

traceable mafic horizons. Both plutons are readily discernable

from the magnetic data. IP was done on every second line and

several weak, broad east--west trending anomalies were outlined,

although they are believed to be reflected by topography.

REGIONAL GEOLOGY

The Tri-Star property is located within the

Sch re i be r-Marathon greenstone belt in the Superior Province of

the Canadian Shield. More specifically, the property lies within

an Archean me tasedimentary-metavolcanic belt trending easterly

from the Heron Bay area on Lake Superior. The Hemlo gold camp is

also located within a portion of the Schreiber-Marathon

greenstone belt, and lies approximately 20 km to the east.

The Tri-Star property is situated within the Heron Bay

Sheet, Map 2439 (see enclosed portion, Fig. 3), which was mapped

by T.L. Muir, and associates for the Ontario Department of Mines

in 1981.

The oldest rocks in the area are the acid and mafic

- 4 -

metavolcanic sequences with their associated interflow

metasediments. In the vicinity of the Tri-Star property, the

belt consists of intermediate to mafic metavolcanic flows and

pyroclastics with monor intercalated tuffaceous-sedimentary

rocks. According to T.L. Muir, (1982, O.G.S. Report 218), the

fragment size in the pyroclastic rocks decreases away from the

vicinity of Heron Bay suggesting that a volcanic center lay

within or near Heron Bay. This portion of the Metavolcanic belt

is sandwiched between two massive plutons, one to the north, the

Gowan Lake Pluton, and the smaller Heron Bay Pluton to the south.

The Gowan Lake Pluton consists of an equigranular to porphyritic

(microcline) biotite-hornblende quartz monzonite. The Heron Bay

Pluton consists of a porphyritic (plagioclase) biotite-hornblende

granodiorite.

All of the above mentioned rock suites are intruded by Late

Precambrian felsic dykes and sills, and diabase dikes. A cannon

orientation of the diabase dikes is nor them ly.

Major lineaments in the region trend north-northwesterly and

northwesterly and can be easily recognized on air photographs.

PROPERTY GEOLOGY

The Tri-Star property is underlain mainly by Archean

intermediate to mafic pyroclastic metavolcanics with minor

associated tuffaceous metasedimentary rocks. These trend

easterly and, according to T.L. Muir, (1982), young to the north.

property by the Heron Bay Pluton, a massive porphyritic

(plagioclase) biotite-hornblende granodiorite. The northern

portion of the Tri-Star property is intruded by the Gowan Lake

Pluton, a massive porphyritic (microcline) biotite-hornblende

quartz monzonite.

The metavolcanic and metasedimentary rock units are

generally well foliated in texture, with lapilli within the

pyroclastic units stretched and flattened parallel to foliation

at about 6:1 (long axis: width). Narrow felsic layers within

intermediate and mafic units are often boudinaged parallel to

foliation.

Minor carbonate alteration occurs in fractures as calcite,

together with minor manganese and hematite stains.

VLF BM

Procedure and Instrumentation

The VLF EM survey was carried out using two EM-16 units

manufactured by Geonics Ltd. (Specifications are included in the

appendix). In phase and quadrature readings were measured using

Cutler, Maine (NAA) as a transmitter. Transmissions were at a

frequency of 24.0 khz. Readings were taken at 20 m intervals

along lines spaced 120 metres apart. All readings were taken

facing north.

Statistics

The VLF EM survey was conducted between August 23-29, 1985,

in the field by two operators from Rayan Exploration Ltd. (Ray

- 6 -

Meikle, Bryan Belanger). A total 42.42 Ion of line were surveyed

resulting in 2121 readings.

Interpretation

Anomalies obtained with the EM-16 equipment can be divided

into two categories:

Type "A" - those in which the quadrature is opposite in sign to the in-phase (negative quadrature) and indicates a strong phase shift due to the overlying conductive overburden. Type "A" conductors are typically due to sulphides, graphite or very strong shears.

Type "B" - those in which the quadrature follows the in-phase (positive quadrature) and indicates a poorly con ductive source such as overburden, faults or shears.

The above separation depends on the conductivity-thickness

of overburden. Consequently, in the absence of overburden, Type

"B" anomalies could represent strong VLF conductors. Therefore

the Type "B" anomalies should be examined in the absence of

overburden.

It should also be noted that weakly pyritized shears and

formations, often of value in gold exploration, usually give rise

to the Type "B" response.

A total of 20 conductors (lettered A to T inclusive, see

Fig. 6 fc 7) have been interpreted from the data. The axes of the

conductors generally strike ENE, E-W or ESE and these directions

are conformable to the geologic trend.

Conductor A is 1440 m long, trending ENE between L 840E and

E-W between L 1560 and L 2280E. This conductor displays a

moderate in-phase response with a corresponding moderate negative

quadrature (type "A" anomaly). The conductor correlates with the

- 7 -

contact between unit Ir and 1m in its ENE trend, and with a long

linear swamp in its E-W trend.

Conductor B is 240 m long, trending ENE between L 1560E and

L 1800E. This conductor displays a moderate in-phase response

with little attendant quadrature response (type "B" anomaly) and

is probably due to overburden/swamp effects.

Conductor C is 600 m long, trending E-W between L 1080E and

L 1680E. This conductor is a weak and discontinuous type "B"

anomaly and may be due to a slightly elevated background content

of disseminated pyrite.

Conductor D is 480 m long, trending ENE between L 1680E and

L 2160E. This conductor displays a moderate to strong in-phase

response with weak positive quadrature (type "B" anomaly). The

western half of this conductor axis is weaker and is probably

caused by a swampy beaverpond and creek, while the eastern half

of the conductor axis may be due to a slightly elevated

background content of disseminated pyrite.

Conductor E is 720 m long, trending E-W between L 2160 and L

2880E. This conductor displays a moderate in-phase response with

a moderate positive quadrature response (type "B" anomaly). The

axis roughly parallels, and is probably due to the contact

between units 1m and 3d.

Conductor F is 340 m long, trending E-W between L 2780E and

L 3120E. This is a weak type "B" conductor that corresponds to

the contact between units 1m and Ir.

Conductor G is 340 m long, 100 m south of conductor F, and

8

trends E-W. This is a weak type "B" conductor that may be due to

a slightly higher diseminated pyrite content.

Conductor H is 600 m long, trending ESE between L 2520E.

This conductor displays a weak in-phase response near L 2520E and

a strong in-phase response near L 2880E, with corresponding

moderate negative quadratures (type "A" anomaly). The conductor

correlates with a long linear swamp, and may be the eastern

extension of conductor A.

Conductor I is 340 m long, trending NE between L2780 and L

3120E. This conductor is a weak type "A" anomaly that may be

caused by a weak struture (fault or shear) in the granodiorite.

Conductor J is 240 m long, trending ENE and ESE between L OE

and L 240E. This conductor displays a moderate in-phase response

with li tt lw attendent quadrature response (type "B" anomaly).

The conductor parallels, and is probably due to the contact

between units 1m and Ik.

Conductor K is 120 m long and is probably two weak, single

point anomalies (type "B"), caused by a linear swamp and creek.

Conductor L is 240 m long and is a weak type "B" conductor,

that is probably caused by a creek.

Conductor M is 120 m long and is a weak type "B", caused by

the same creek as conductor L.

Conductor N is 120 m long, trending ESE between L 480E and L

600E. This conductor portrays a weak to moderate in-phase

response with little corresponding quadrature (type "B" anomaly).

This conductor parallels conductors L and M, and may reflect a

- 9 -

weak structure (fault or shear).

Conductor O is 240 m long, trending ESE between L 480E and L

720 E. This is a weak type "B" conductor that parallels

conductors L, M and N, and may reflect a weak structure (fault or

shear).

Conductor P is a weak type "B" anomaly across two lines, and

it is probably due to conductive overburden.

Conductors Q, R, S and T are weak, type "B", single point

anomalies that are probably caused by overburden affects.

Rock Sampling Program

Procedure and Statistics

None of the samples were considered anomalous in Au, Ag, Cu,

Zn, and of the 19 samples (above) considered anomalous in

indicator elements, none are multi-element anomalies (more than

one element anomalous in the same sample). Also, of the above 19

anomalous samples, all are considered only weakly anomalous

except for TS-29 and TS-69.

TS-29 is moderately anomalous in arsenic (21.1 ppm). It

should be noted that greater than 50 ppm As is considered

anomalous at the Hemlo gold deposits.

TS-69 is moderately to strongly anomalous in barium (8220

ppm). However, wihin the "Hemlo camp", it is not unusual to have

highly anomalous barium values scattered within volcanoclastics

and metasediments, with no accompanying mineralization or

alteration. This may be caused by the mechanical weathering of

barium-feldspar, rather than the formation of barite.

OONCUJSIONS AND REOCMVIEEDATIONS

Although 20 VLF-EM conductors of variable strike length and

strength were defined on the property, none of them have been

interpreted to be directly caused by an appreciable sulphide

- 20 -

content within underlying geology. Anomalies outlined by IP

surveying in 1983, are weak and do not correlate with the VLF

conductors outlined in this report.

Of the 102 rock samples collected from outcrops on the

property, none are considered anomalous in gold, but 19 are

considered anomalous in indicator elements.

In light of the fact that none of the VLF-BW conductors

correllate with the existing weak IP anomalies (obtained in

1983), and that none of the rock samples returned anomalous in

gold, no further work is recorrmended at this time.

VLF ELECTROMAGNETIC UNIT

Pioneered exclusively by Geonics Limited the VLF-method of electromagnetic surveying by utilization of the uniform horizontal fields generated by an existing network of reliable, fully operational Very Low Frequency trans mitting stations has proved to be a major advance in geophysical exploration.

Very extensive world-wide experience since the beginning of 1965 by a large and rapidly increasing number of users, including a high proportion of major mining and exploration companies, has provided conclusive evidence of the effective ness of Jthe technique and the EM 16 has gained general acceptance as a basic electromagnetic tool. This evidence has also indicated the response of dissemin ated bodies, to the VLF-method.

The unique self-contained EM 16 offers the unrivalled combination of LIGHT WEIGHT, ONE-MAN OPERATION and DEEP PENETRATION allowing rapid, economical surveys. Assessing the data is simplified due to the use of the uniform horizontal primary field. The patented design feature of the measurement of both the in-phase and out-of-phase (quadrature) component of the vertical field provides the information necessary for comprehensive interpretation of the field results.
