SUMMARY

An exploration program designed to further evaluate the Clement Option Claims was recommended in a 1985 Report by Gow and Flood for Lincoln Reources Inc.. This included a) picketing lines at 100 foot intervals in the areas of anomalous samples , b) cleaning out and reampling the old trenches c) carrying out detailed, mapping and prospecting about the anomalous areas and d) carrying out detailed geophysics to outline sulphide concentrations more accurately. The present owners of the claims , Kowash Gold Corp. in conjunction with Tusk Minerals Inc. who have an option to earn a 50;E interest in the claims, decided to proceed with a) and d) , to evaluate these results and then to decide the next step in the exploration program. Accordingly a detailed high sensitivity ground magnetometer and VLF Electromagnetic survey was carried out in November-December of 1987 and combined with a geological and structural interpretation. It is the purpose of this report to describe the results of the geophysical survey.

To prepare for the magnetic survey a system of lines were cut and chained in a north south direction at 100 foot intervals with stations every 50 feet. This close grid was necessary because of the doubtful value of the geophysical work done in 1985 on 400 foot line intervals and because in searching

Page 3

efor gold mineral zones every effort must be made to resolve the geology in as greatest detail as practical.

The survey was carried out using a Scintrex IGS System with an MP-4 Proton magnetometer with portable sensor and a compatible base station and a VLF - A Electromagnetic sensor. During the course of the survey and considering the snow cover as many as possible samples of outcrop were collected for geochemical analysis . Claim posts where seen were tied into the grid.

The geological/geophysical interpretation entailed plotting, contouring the magnetic data and profiling the VLF readings, comparing these results to known geology or 'sample identification of those collected during the present survey and giving an overall graphic of the data.. This having been done the interpretation of the combined data yielded a clearer picture of the relative location of previous work to the new and detailed information.

Several distinct zones of interest were developed and recommendations for further work are presented herewith.

INTRODUCTION

A 21 claim gold prospect in the Old Cabin Lake area in Jacobson Township in the Sault Ste. Marie Mining Division of Ontario has been acquired by Kowkash Gold. Corp. Kowkash , in turn have given Tusk Mineral Inc an option.to earn a 501 interest inthe claims by performing certain work..The location of ..the property is shown on Figure I.. The property is located in the Localsh-Goudreau area NE of Wawa Ontario which has had a history of gold production over the years and wherein production plans have been announced for 1988 for the Magino and Kremzar properties a few mile west of this location and in the same geological setting.

On previous occasions dating back into the 1920's other operators explored this property. Many large trenches were hand dug by the earlier operators , some broad scale ground and airborne geophysics was done and a limited amount of diamond drilling for which only rudimentary logs , no assays and no accurate locations exist. The last work done on the property in 1985 for Lincoln Resources consisted of a very quick mapping job on the existing 400 foot lines , some magnetic surveying of questionable quality and some VLF electromagnetics.The claims were allowed to lapse , were restaked and optioned to Kowkash Gold Corp.

Kowkash Gold Corp. ,in turn granted an option to Tusk Minerals Inc. to earn by performing certain works .A high sensitivity magnetometer and VLF electromagnetic survey was carried out in Novemebr - December of 1987 on a 100 foot grid with stations at 50 foot intervals. Some 20 miles of line were covered. The magnetometer readings corrected for diurnal variation , plotted and contoured and the VLF readings plotted and profiled. The samples collected were identified as to rock type and location and analysed for gold,silver,copper,arsenic and chrome .A structural study of the air photos was done -presented under separate cover - and all data related to previously known geology.geophysics trenching etc..

Recommendations for further work were forthcoming as a result of the overall interpretation of these data.

The purpose of this report is to describe the geophysical survey work and it's geological interpretation A summary of the labour and costs has been compiled so that these all may be accepted as assessment credits against certain of the claims.

PROPERTY DESCRIPTION

The Old Cabin Lake Lake property acquired -by Kowkash Gold Corp. is located in Jacobson Township in the Sault Ste. Marie Mining Division in the Province of Ontario. It consists of 21 unpatented mining claims which may be more particularily described as follows :

SSM 971062 - 63 inclusive ( 2 claims)SSM 971066 - 75 inclusive (10 claims)SSM 971092 - 100 inclusive ( 9 claims)

Total 21 claims

The total area is about - 840 acres . The claims were recorded on January 21,1987 and are in good standing until January 21,1988.The present work will hold certain of the claims in good standing for a further 12 month period and an extension has been appllied for the remaining claims pending the completion of the next phase of the work.

LOCATION AND ACCESSIBILTT

The property is situated in the south east quarter of Jacobson Township in the Localsh - Goudreau gold district of Ontario.. The claims are about 50 kilometers ( 30 miles) north east of the town of Wawa,Ontario.

Page 5

Access to the property is by paved road from Wawa to Dubreuilville, thence west by unimproved road to Localsh for a total of 102 kilometers (64 miles) . A boat or canoe trip up the Tehoama River from a point near Localsh takes one to the property itselfat certain times of the year. The claims may also be reached by float or ski plane or helicopter. A drill trail from the Localsh-Goudreau road to Godin Lake and thence along the Tehoama River system could be used after freeze up to bring a drill and equipment to the claims . There is said to be another access by drill trail from the west however it's precise location or condition is not known at this time.

TOPOGRAPHY .TIMBER AND WATER

Topographically the property is- typical Precambrian Shield with rounded hills ,alder and cedar swamps in low-lying areas and relatively little rock exposure.

Forest cover is mixed spruce,jack pine, birch and poplar with plenty of good trees available for exploration and development activities.

An ample supply of water is available for all mining activities from the Tehoama River system and Old Cabin Lake.

GEOLOGY

The property lies within the Michipicoten Greenstone belt which has seen considerable exploration activity over the period since the turn of the century year . The belt trends northeasterly and and has been the subject of a number of federal and provincial geological studies which have identified major folding and faulting in the area. This Greenstone Beltv encompasses several former producing gold mines including the Cline Lake,Edwards .Algoma Summit (Magino) and Amherst (Murphy Lake). Gold production from the Localsh Goudreau area has been reported by Bruce ( ODM Vol. XLIX 1940) to be 40,623 ounces Recent activity has sharply increased as a result of the major gold ore reserves developed at the Magino and Kremzar properties (1,900,000 tons, of 0.25 oz.Au /ton and, 1,025,000 tons of 0.25 oz.Au/ ton respectively) -. 1988 production plans for both properties have been announced.

The geology of the Localsh - Goudreau area was mapped by E.S.Moore in 1930 ,by E.L.Bruce in 1940,with a compilation of data shown on ODM map P 184 issued in 1963; other studies have been done more related to the iron ore deposits of the area.Map No. P.184 of the Ontario Department of Mines , shows the surface

Page 6

and structural geology of the area on a scale of l inch * 2 miles. Bruce has mapped the outcrop geology in the area on a scale of l inch equals 2640 feet .He appears to have done most of his traversing in the area of the Clement property along claim lines .Outcrops on the property are sparse, less than 15 per cent of the total area , the remainder being covered by glacial debris, swamps, streams and lakes . The rock types displayed by Bruce"s outcrops include diorites, lavas (mainly basic) , iron formation and diabase. Other workers on these claims have recognized the presence of quartz porphyry , ultrabasic ( dunite and peridotite ) and gabbro. ,

Structurally the claim group is located on the north limb of the Centre Anticline (ODM Map P.184) and near the projected intersection of a strong northeasterly trending fault just south of the claim boundary and a northwesterly trend identified in the north east quarter of Jacobson Township. The ever present diabase dikes appear to occupy north trending zones of structural weakness - several of these are known on the claims.

HISTORY

General

Exploration for gold in the Localsh - Goudreau area dates back to the early 1900 s and has continued intermittently to the point where the price of gold was freed from $3S per ounce. After this latter point in tine activity has been continuous leading to anounced production plans for the Kremzar and Nagino ore bodies for 1988.

By 1936 there had been a total recorded production of 1,038 ounces. Cline Lake Gold Mines bagan active development in 1936 and by 1939 had produced some 29,620 ounces. Minor production came from the Amherst,Magino, Edwards and White properties making up a further 11,000 ounces to 1939.

Previous owners of the Clement claims have recorded the results of their efforts as assessment work.These include Erie Canadian Mines who in 1938 reported on, five trenches that were sampled on the claims. These included a trench on present day claim 971099 that assayed 0.07 oz.Au/ton across a 3 foot quartz vein and 0.14 oz. across a 10 foot porphyry zone.A^ trench in present claim 971100 assayed 0.01 tO 0.02 across a 36 foot width of mineralized greenstone and a trench across a 40 foot mineral zone in 971068 was said to have panned gold , a fact not confirmed in a channel sample. Three claims that may be covered by the Clement group were drilled in 1947 by an unknown party ;

Page 7

t '-" t

the logs are very brief an dfo assays are given .In 1966 Bert Lang had an airborne magenteic and electorraagnetic survey flown which indicated a strong magnetic anomaly with some association of conductivity ; this has been confirmed by later ground geophysical surveys including the one being reported on herein and those of Canex Aerial in 1968-69, Gulf Minerals in 1977 - 78 and Lincoln Resources in 1985 .

Other work has been done for which there are no assessment records including a large amount of trenching on Clement claims 971067,971069,971070 and 971072 . In 1985 Lincoln Resources obtyaned anomalous gold values of from 600 to 1100 ppb in their program. These trenches are said to have been hand dug in the 1920s and 1930s by gold explorers; it is hard to believe that such a large amount of hand work would have been done without there having beens ome encouragement. The lie along the axis of the VLF conductor turned up by this survey.

Other properties in the immediate vicinity of the Kowkash - Tusk claims include the Reed showing to the west and the Godin Lake-Michael Webb showings to the north. Both yielded economic grades and widths of gold mineralization for previous operators.

The Reed showing located some 2000 feet west of claim 971097 and striking SSOdegreesW reports a vein length of 550 feet with an average width of 5.6 feet in 11 trenches . Six of these trenches were sampled in 1939 and gave values of 1.35 oz of gold across 7 feet,2.26 oz. across 6 feet,1.35 oz across 3 feet,0.01 oz. across 4 feet and 0.94 oz. across 4 feet.

The Godin Lake showing has had a large amount of work done on and around it. The original Michael Webb show in 4 trenches over about 800 feet of length gave values for Erie Canadian Mines in 1938 of 0.09 oz.of gold across 4 feet,0.07 oz.across 8 feet and 0.12 oz. across 9.4 feet.

DESCRIPTION OF 1987 GEOPHYSICAL SURVEYS

Linecutting

A linecutting crew under contract to G.Clement of Localsh commenced a 100 foot grid with lines running north south and stations each 50 feet on November 16,1987. They used the old Base Line at 25+00 south as a starting point but were confused as to the chainages resulting in very mixed up situation when the geophysical crew arrived. Most of the misleading chainages ( they measured everything as south of the 25S base line regardless of direction north or south) were corrected by the geophysical crew however a few bad chainages may still be in place.

18.7 miles of line were done by this crew and an additional 1.3 miles were set out on Old Cabin Lake by the geophysical crew.

High Sensitivity Magnetics

A detailed magnetic survey was carried out using a Scintrex MP - A Proton Magnetometer sensor head tied into the IGS 2 system . This instrument has a sensitivity of 0*5 gamma, more than adequate for this survey. A stationary base using a similar magnetometer powered by a car battery was positioned at the camp , approximately 600 feet from the centre of the grid* After each days surveying the two units were connected and the day's readings computer corrected for diurnal effects. The corrected data were output by a dot matrix printer in tabular and graphic form and analysed for possible problems* None were found and a high level of confidence that a survey with a reliability within 2 gammas has been achieved.

All corrected readings were posted to a base map with a scale of l" equals 100* a.nd then contoured at appropriate intervals, i.e. larger intervals in areas of higher intensity and smaller in areas of weak magnetics.

VLF Electromagnetics

On the same frame as the Proton mag sensor was carried a VLF-4 electromagnetic system. This technique makes use of the electromagnetic fields generated by Very Low Frequency radio stations scattered around the globe and used to communicate with NATO nuclear submarines. These fields can be locally distorted by surface or near surface conductivity and this is what is measured

Page 9

and analysed. Normally more than one VL frequency is observed however in the present case the Cutler Maine station ( 24.0 kHz) was the only reliable one as Annapolis was down most of the time and Seattle is too far away.

Although three parameters were measured at each station only the vertical in-phase and horizontal field strengths were plotted and these only for the western part of the survey area as the equipment was malfunctioning when the eastern part was covered.

DISCUSSION OF RESULTS

The contoured magnetics clearly show the large magnetic zone that has been picked up by previous surveys .It runs from one side of the survey area ( Line 8E) to the other (Line 68E). Some samples were collected from this zone that indicate it is caused by a basic to ultrabasic intrusive ranging in composition from diorite to peridotite and not by iron formation as suggested by the Lincoln Resources geologists. In addition several zones with the distinct magnetic signature of the ubiquitous diabse dikes were disclosed - these were missed by previous surveys probably because of the larger line spacings used or in the case of the Lincoln Resources survey by the poor quality of the data.

Other magnetic features include a semi continuous east west zone,north of the major anomaly which appears to be associated with the old trenching and with the VLF conductor axis. Some faulting of the main anomaly is indicated in the eastern part of the survey area .

The VLF results reveal a continuous conductor from Line 8E.11S to Line 44E.18S where the VLF coverage ceases.

The maps enclosed as Figures 2 and 3 display the magnetics,VLF electromagnetics, sample locations and interpreted geology . A report on the the airphoto studies and sample analyses has been prepared by W.D.Sutherland M.A.Se. and is included as Appendix I.

CONCLUSIONS

Prior surface and airborne work done in this area succeeded in defining an excellent gold prospect which has never been fully investigated.There has been extensive trenching strongly indicating the presence of values of interest however no records exist for this effort in the north part of the property.Trenching done in 1938 by Erie Canadian outlined three

Page 10

zones of interes , one of which assayed 0.14 oz.Au/ton across 10 feet. Rock samples collected by Lincoln Resources showed two other areas where anomalous gold values turned up , the one from the old trenches referred to above and the other from a pit near line 64E.24S. Other nearby showings , the Reed to the west and the Michael Webb to the north have yielded gold values of importance, thus confirming the exploration potential of the region east and along structural strike from the Magino, Kremzar and Cline ore bodies.

The present geophysical surveys have been able to confirm a magnetic and conductive zone parallel to the main intrusive anomaly and coincident with some of the old trenching. The location of diabase dikes has been another . success of the high sensitivity magnetic survey on a close pattern not previously accomplished.

The identification of the structural pattern is essential in order to understand the controls of the related gold mineralization found in this area. Studies of air photos have been done independently of this report and will be used to assist the setting out the precise drill locations for the next phase. These are reported on in Appendix I.

This present program has served to enhance the merit of a known gold prospect in the south eastern qifrter of Jacobson Township in the Localsh - Goudreau area .Some further geophysics and a drilling program to follow' up this work has been recommended. -

APPENDIX I

DISCUSSION OF AIR PHOTO STUDIES

l The predominant linear trend in the study area is NE - SW. This trend is parallel to the glacial movement and does not necessarily reflect subsoil structure.Where .however,structural mechanisms have accelerated rock degeneration the effect will be enhanced by glacial scouring.

2. High priority linears are those trending in an east west direction similar to known gold bearing shear zones elsewhere in the area . The priority is enhanced if the linear is proxiamte to a volcanic - granodiorite contact.

3. NNW trending linears are interpreted to be caused by late Precambrian diabse dikes or late stage block faulting along zones of structural weakness which may or may not be filled by dikes.

Potential drill targets that have been identified by this study are:

i) An arcuate linear at 76+00 S,58+00 E,This linear is 1600 feet long and flanks an outcrop of granodiorite. It is probably the surface expression of the volcanic - granodiorite contact.

ii) A strong E-W linear entering Old Cabin Lake at 31+505, 69+OOE . The linear projects west into the lake on the subject claims. This is a high priority target and should be tested from the ice on Old Cabin Lake.

iii) A N 70 degrees W striking linear at 42+OOS, 54+OOE. This is a very prominent linear which is 2100 feet long.It is located along a possible shear contact between rhyolite and basic volcanics and may truncate the iron formation which is mapped 500 feet to the south .This linear is near old gold trenches.

iv) One north east linear was designated for drill testing. This lies along the creek between 25+OOS,18+OOE and 17+005,32+OOE.The recommended location for an initial hole is at the south west end near 18+OOE.25+OOS near the rhyolite- basic lava contact.

Page 14

o NOTE: the north east end of this trend coincides with an intersecting northeasterly trend supported by the magnetics,a northerly trending linear ,a VLF conductor axis and a magnetic high . The magnetic high and the conductor coincide with old and extensive trenching further west. This location at 33+008,16+005 is considered a top priority drill target.

J.B.Prendergast,Jan.20,1988

There is no obvious relationship between the magnetic expression and those drill targets ( ii and iv ). However it is possible that magnetic profiles will show a correlation with low shouldering corresponding to the trace of the targets. This would suggest alteration and/or silicification - both favourable indications for gold . Only two of the targets are in the surveyed grid - ii) and iv). It is recommended that that the geophysical coverage be extended to cover targets i) and iii) as a top priority.

It is also recommended that potential targets defined in the geophysical interpretation be examined in a future structural review . Any trends indicated in the magnetic profiles should be checked out on the^ stereo photos especially those related to magnetic lows and magnetic trend disruptions.

and analysed. Normally more than one VL frequency is observed however in the present case the Cutler Maine station ( 24.0 kHz) was the only reliable one as Annapolis was down most of the time and Seattle is too far away.

Although three parameters were measured at each station only the vertical in-phase and horizontal field strengths were plotted and these only for the western part of the survey area as the equipment was malfunctioning when the eastern part was covered. -

Rock Geochemistry

The survey work was originally scheduled to commence before freeze-up but delays in getting approval to proceed precluded this happening. As a result only 36 outcrop samples were collected and analysed due to snow cover and the antiquity of the major trenching. The sampling of outcrops was not a prime objective of the work but was considered something potentially useful in identifying the rock types associated with geophysical phenomena and to investigate possible "key element" halo effects near mineralization. In this latter regard all samples after having been described lithologically were sent for analysis for gold, silver,copper,arsenic and chromium.

Air Photo Structural Study

Steroscopic air photo coverage was obtained for the south portion of Jacobson and Riggs Townships. A two phase structural study was made of the claim group from these by W. Donald Sutherland. The first phase involved delineating photo linears, normal indicators of geological structure and the second of relating the geophysical results to air photo evidence.

DISCUSSION OF RESULTS

The contoured magnetics clearly show the large magnetic zone that has been picked up by previous surveys ,It runs from one side of the survey area ( Line 8E) to the other (Line 68E). Some samples were collected from this zone that indicate it is caused by a basic to ultrabasic intrusive ranging in composition from diorite to peridotite and not by iron formation as suggested by the Lincoln Resources geologists. In addition several zones with the distinct magnetic signature of the ubiquitous diabse dikes were disclosed - these were missed by previous surveys probably because of the larger .line spacings used or in the case, of the Lincoln Resources survey by the poor quality of the date
