INTRODUCTION

The Rowan/Martin Bay Property survey covered mining claims numbered KRL 200009,

KRL 200010, KRL 200011, KRL 200012, KRL 200013, 10371, 623493, 563668, 563667 and

563666 situated in Todd Township, Northwestern Ontario, Red Lake Mining Division.

The subject claim group covers a long zone of interlayered volcanic rocks containing

quartz veins and chert-magnetite iron formation with reported gold, with minor pyrite,

chalcopyrite, sphalerite and arsenopyrite.

Dan Patrie Exploration Ltd., was requested by Goldcorp Inc., to carry out a limited

program of exploration on their acquired property to establish areas of disseminated sulphide with

possible gold content. It was recommended that a gradient induced polarization survey to better

define the ore potential within the subject property. The following report summarizes the results

of the previous work, the work carried out during the current program and the results obtained

from that work.

SUMMARY AND RECOMMENDATIONS

Between April 11, 2002 and April 15, 2002 a gradient induced polarization survey was

completed on a portion of the Rowan/Martin Bay Property. A total of 16.2 kilometers of line

cutting with base line and lines turned with a transit and 13 kilometers of induced polaization was

read and a zone of high chargeability and resistivity high interpreted to be caused by a highly

altered carbonatized l or silicified zone with disseminated sulphide in iron formation which is a

typical signature for many gold properties. The zone is considered to cover a large area of

disseminated sulphide and iron formation and may hold gold bearing sulphide.

It is recommended that the following program be carried out on the property to complete the

evaluation.

l. Completion of the grid lines at 50 meters over the total claim group.

3. Completion of induced polarization survey.

4. Total field and gradient magnetometer survey.

Following completion of this work and contingent upon the results then additional work

could be considered to further evaluate the economic potential of the property for gold and base

metal mineralization.

PROPERTY LOCATION AND ACCESS

The Rowan/Martin Bay Property mining claims located in the Red Lake mining camp of

Northwestern Ontario.

The claim group is situated in part on the west side of Martin Bay and going north and

west with the survey covering only a portion of the claims in Todd Township, approximately 22

kilometers the town of Cochenour by snow machine to the northwest end of Red Lake or by truck

traveling 18 kilometers north up the Nungesser road and turning west onto pine ridge road for 21

kilometers and then turning onto the Mount Jamie Mine road for another 18 kilometers where the

grid survey was started.

TOPOGRAPHY AND VEGETATION

The Rowan/Martin Bay property is covered with a mixture poplar and birch with small

areas of spruce and balsam and also areas of second growth because of past logging activity.

WORK DONE

A gradient induced polarization survey was done over the Rowan/Martin Bay Property.

The survey which was a gradient array which better defines the contact where two electrodes ci

and c2 which are placed at a fixed distance off each end of a survey line which is usually the line

most centered and a continuous voltage at 2 second on and 2 second off cycle pulse is transmitted

to these 2 electrodes and approximately 4 amps was transmitted during this survey.

PageS

This array generates chargeability and resistivity reading at every station read and collected with

an I. P. R-12 receiver and downloaded to a computer for plotting. A highly conductive zone such

as massive sulphide would have a high chargeability with a low resistivity where a disseminated

silicified zone would have a high chargeability and a high resistivity typical for a gold property.

The survey was performed using a Scintrex time domain I. P. R-12 receiver, an MG-12

motor generator revamped by Walcer Geophysics and a Huntec 14 kilowatt transmitter also

revamped by Walcer Geophysics to produce more voltage and with readings taken every 25

meters. A total of 13 kilometers of induced polarization was read and plotted and is presented in

this report.

GEOLOGY

REGIONAL GEOLOGY

The Red Lake area is underlain by a 60 x 30 kilometer irregularly-shaped belt of

metavolcanic and metasedimentary rocks surrounded and intruded by diapiric granitoid plutons.

According to Pirie (1981), the belt consists of 2 predominately volcanic successions; a lower

tholeitic to komatiitic sequence, and an upper calc-alkaline sequence.

The older volcanic sequence has three main types of volcanic flows: tholeiitic basalt,

variolitic basalt, and komatiites (Pirie, 1981). Felsic pyroclastics with minor flows and

metasediments also occur within this sequence.

The calc-alkaline sequence is more complex (pirie, 1981). Substantially different volcanic

lithologies are intimately interbedded and interdigitate laterally, suggesting extrusions of volcanics

of different composition from different sources. Quartz-pyric rhyolite flows, tuffs, lapilli stones

and breccias with intermixed dacitic to andesitics equivalents are abundant. Andesite to basaltic

flows are common as well.

U-Pb dating indicates a prolonged period of volcanic activity evolving from tholeiitic to

dominantly calc-alkaline affinity and spanning an interval of at least 2700 Ma (Andrews et al,

1986). The supercrustal rocks have been intruded by a variety of felsic to intermediate stocks and

dykes, such as the "Howey Diorite", just east of Red Lake and the "Dome Stock." A granidiorite

in the center of the batholiths to the north marks the beginning of major felsic plutonism in the

belt at 2731 &2717 Ma respectively, and culminated in the emplacement of the Killala- Baird and

Trout Lake batholiths at approximately 2700 Ma ( Andrews et al, 1986).

The structural signature of the Red Lake green stone belt is dominated by the subvertical

to vertical attitude of the stratigraphy and the widespread development of a penetrative L-S

fabric, the latter accompanied by a variety of related brittle to brittle-ductile features (Hugon &

Schwerdtner, 1984, 1985). The regional fabric manifests in the pervasive foliation and cleavage

development which in the vicinity of batholith contacts, increases in intensity to define 2-3

kilometer-wide strain aureoles of strongly deformed schistose to gnneissose supracrustal rocks.

Foliation trajectories obtained from the foliation data available at the belt scale

demonstrates that large and small scale conjugate trans-current shear zones developed within the

supra crustal material of the belt. These sets of shear zones form discrete linear zones of high

strain (deformation zones), superimposed on the regional trends. These deformation zones occur

at the interface between the older and younger volcanic piles.

The combined structural evidence indicates that formation of the regional foliations and

Page?

conjugate systems of the deformation zones was broadly synchronous and temporarily related to

the diapiric emplacement of the surrounding batholiths (Hugon A Schwerdtner, 1984).

Past and present producing mines in the Red Lake camp occur in zones of highly altered

rock near the stratigraphic top of the lower tholeiitic sequence. A few past producers located

within the Dome Stock and related McKenzie Stock represent the only exceptions.

The major Gold deposits of the area and the highly altered rocks associated with them are

spatially related to the large heterogenous shear systems (deformation zones), which cut across

the volcanic sequences on a regional scale.

Studies by Andrews et al, (1986), in the Campbell and Dickenson Mines indicate that gold

mineralization was broadly synchronous with the peak of thermal metamorphism but post-dated

much of the carbonated alteration and occurred late in the history of shear deformation.

The combined evidence indicates that contact thermal metamorphism, shear deformation

and intense hydrothermal alteration attending gold mineralization were broadly coeval and directly

lined to the process of batholith emplacement.

PROPERTY GEOLOGY

The property covers a northeast striking zone of interlayered volcanic rocks and chemical

sediments containing mineralized sections that reportedly carry gold with minor pyrite,

chalcopyrite, sphalerite and arsenopyrite with quartz veins and chert-magnetite iron formation

(Bishop 1934).

PageS

INTERPRETATION

There is a wide zone of high chargeability with a corresponding resistivity high across the

property running in an east west direction from line O to line 400 south open to the north and also

a small zone at the end of lines 100 west to 300 open to the south.

The chargeability zone running across the property is well above background and are

consistent with metallic mineralization. The bulk resistivity values are also well above background

and are caused by electrolytic polarization as opposed to the combination of electrolytic and

electrode polarization in case of metallic mineralization. The zones may be due to disseminated

sulphide mineralization which could hold gold.

CONCLUSIONS

A total of 13 kilometers of Induced Polarization was carried out on the Rowan/Martin

Bay property and has indicated a prominent chargeabilty zone with a resistivity high which is

interpreted to be caused by disseminated sulphide content which could hold gold and that the

property should be looked at in more detail and possibly drilling the known anomalies.

Due to a lack of geological information from the property, it is suggested that on-going

work should consist of a program of drilling and more ground geophysics to evaluate the results

obtained by this survey.
