SUMMARY

Consolidated Gold Win Ventures Inc. has acquired by option agreement, the GTEN #9 mineral claim located 50 kilometers southeast of the city of Yellowknife, NWT. on the eastern shore of Great Slave Lake.

The property is underlain by Archean granitic rocks intruding Burwash Formation sediments of the Yellowknife Supergroup.

A diamondiferous kimberlite occurs beneath a small bay near the mouth of Drybones Bay to the north west of this property.

The airborne geophysics indicates the occurrence of anomalies on the property with close affinities to the anomaly associated with the kimberlite.

A program to define the airborne magnetic anomalies, consisting of ground magnetic surveys and initial drilling is recommended at a total estimated cost of $100,000.

INTRODUCTION AND TERMS OF REFERENCE

With the renewed diamond exploration interest being sparked by the New Shoshoni Ventures activity in the Drybones Bay area of Great Slave Lake, Northwest Territories, Canada, several areas of interest identified in the initial 1990's diamond exploration frenzy including Consolidated Goldwin's property were acquired. This area had been covered by staking for Southern Era, DeBeers and others in that exploration period which resulted in the discovery of one operating, one under construction diamond mine and several very advanced and potential diamond operations.

The 1 mineral claim located 50 kilometers southeast of the city of Yellowknife, N.W.T. on the eastern shore of Great Slave Lake has been purchased outright by Consolidated Gold Win Ventures Inc. from a private company.

The author was retained by Consolidated Gold Win Ventures Inc. to collect and review the relevant data and to recommend an appropriate program of work in order to further explore the mineral prospect.

The author has relied only on his visit to the site and on reports and data by previous qualified persons who reported on the various exploration programs carried out between 1994 - 1996.

DISCLAIMER

The property, north of the east arm channel of Great Slave Lake was not visited directly but the outcrops of the area, where possible, were inspected between January 14 - 19, 2002.

PROPERTY DESCRIPTION AND LOCATION

The property consists of 1 located mineral claim totaling approximately 200 hectares described below

The claim is located in Southern Mining District, NTS Map 85 I 4, N.W.T. Co-ordinates of the centre of the property are 62° 01¢ North Latitude, 113° 13¢ West Longitude.
The property title includes the mineral rights and assessment work in the amount of $2.00 per hectare per year prior to the expiration date must be performed in order to keep the claims in good standing.
The property has not been legally surveyed.
The claim is held outright by Consolidated Gold Win Ventures Inc. as detailed in the attached newsrelease.
The author has been informed by Consolidated Gold Win Ventures Inc. that necessary permits for performance of geophysical work and diamond drilling are pending. There appear to be no undue environmental concerns for the execution of an exploration program on the property at this stage.

ACCESS, CLIMATE, TOPOGRAPHY AND VEGETATION

The property is located 50 kilometers southeast of the city of Yellowknife, Northwest Territories on the northeast shore of Great Slave Lake centred approximately 62° 10' North / 113° 47' West. Yellowknife is serviced by several commercial flights daily from Edmonton and a number of local charter aircraft and helicopter services are available. The city has a population of approximately 18,000 and boasts of all of the up to date conveniences.

Access to the property is by boat, ski or float equipped aircraft or helicopter or by winter ice road.

The property is located near the northern extremity of the northern interior climatic region and is characterized by a cold, dry, sub arctic climate. Mean January and July temperatures are below -30°C and 10° - 30°C respectively, and the mean annual precipitation is approximately 200 mm or less.

Topography of the region is subdued, with elevations ranging from 156 m at Great Slave Lake to 245 m south of Watta Lake to the east of the property. Lakes and low lying swampy areas are common and comprise some 20% of the land surface. The major drainage is the Beaulieu River, which traverses the eastern part of the region, from north to south, and empties into Great Slave Lake.

Best coverage of the property for ground geophysical surveys and drilling of the known kimberlite body and magnetic anomalies would be accomplished during the winter months when the lakes and swamps are frozen, the season being from December to June.

This report is limited to further exploration of the claims. Local drill contractors and personnel are readily available in Yellowknife.

Should the prospect proceed to an advanced stage, detailed studies regarding tailings disposal, processing plants, water, power etc. would be required.

HISTORY

The property was staked in 2002 by Mr. David Smith, the prospector, who first recognized the Drybones Bay area as potential for the occurrence of a kimberlite pipe. This kimberlite occurrence on the adjacent property was confirmed in initial drilling in the early 1990's.

The property was staked by various companies (including Southern Era and Trade Winds Resources) at various times in the 1990's in conjunction with the activity on the Drybones Bay Kimberlite.

Low-level helicopter magnetic surveys, part of larger regional surveys, were flown over the area. A detailed survey was flown over the area of this claim.

REGIONAL GEOLOGY

The property is situated within the Slave Structural Province of the Canadian Shield, which is a small Archean nucleus within the large North American Craton.

This relatively small Archean craton (approximately 213,0000 sq. km) consists of a number of turbidite-filled supracrustal basins and associated marginal volcanic belts, remnants of pre-existing granitic crustal rocks, and numerous later granitic plutons.

The sedimentary supracrustal rocks known as the Yellowknife Supergroup overlie the earlier granitic rocks, and have been metamorphosed to greenschist facies. Sets of Proterozoic diabase dikes in at least three directions cut all of these rocks and show up as obvious long narrow magnetic anomalies.

Regional geology is presented as Figure 3 of this report.

DEPOSIT TYPE

KIMBERLITE MODEL

Kimberlite is a hybrid, volatile-rich potassic ultramafic rock which is thought to be derived by partial melting of carbonated peridotite in the mantle at depths in excess of 150 km. It consists principally of olivine with lesser amounts of phlogopite, diopside, serpentine, calcite, garnet, ilmenite, spinel and, rarely, diamond. Emplacement of these rocks, which is controlled by deep-seated structures is rapid, possibly 10 to 30 km per hour and as high as several hundred km per hour for the last 2 to 3 km. Near the surface, kimberlite bodies, often comprising multiple intrusive phases, take the form of small, carrot-shaped volcanic pipes or diatremes that are accompanied by associated dykes and sills (fig. 3). Ideally, an un-eroded pipe would have three components: a deep (2 to 3 km below surface), volumetrically small "root zone" consisting of crystallized kimberlitic magma extending for a vertical distance of about 05. km; a "diatreme zone" 1 to 2 km in height and reaching to within 300m of the surface, which is characterized by a large volume of kimberlite breccias and other fragmental rocks resulting from gaseous explosions; and , lastly, a "crater zone" comprised of kimberlitic pyroclastic material. At the surface, the pipe may be expressed as a maar surrounded by a low accumulation of pyroclastic debris known as a tuff ring. Kimberlites tend to occur in clusters of 6 to 40 pipes, with each cluster occupying an area some 40 km in diameter.

Kimberlite is considered to be the major host for, but not the source of, diamonds. The observation that diamonds are often very much older (900 to 3,000 My) than the enclosing kimberlite (90 to 1200 My) indicates that the diamonds crystallized from rocks other than kimberlite and were "stored" for long periods of time in regions of high pressure and relatively cool temperatures prior to being transported to the surface. Recent research suggests that the source rocks are eclogite and garnet peridotite, (harzburgite and, to a lesser extent, lherzolite), that are present in "mantle roots" beneath areas of thick, stable continental crust, known as cratons, at depths of approximately 150 to 200 km. Almost all kimberlite pipes containing economic concentrations of diamonds are found on those portions of the cratons that are Archean in age.

During the ascent to the surface, the kimberlite magma passes through the source rock and possible diamond storage area, thus being contaminated with diamonds and various indicator minerals (pyrope garnet, eclogitic garnet, chrome diopside, chrome spinel, magnesian ilmenite) as well as xenoliths of the parental eclogite and garnet peridotite. These xenoliths once entrained in the rising magma, may undergo further fragmentation, yielding smaller xenoliths and xenocrysts.

PROPERTY GEOLOGY AND MINERALIZATION

The property is thought to be underlain by granitic rocks varying from granite to granodiorite of the Archean Defeat Plutonic Suite intruding Burwash Formation sediments consisting of greywacke, siltstone and mudstone, part of the Yellowknife Supergroup.

Locally, the intrusive rocks contain many inclusions of the sedimentary rocks which are metamorphosed to amphibolite grade.

The area of the claim has some mapped glacial features indicate that the ice flow trended in a west south west direction.

EXPLORATION

Except for the air borne surveys no exploration has been reported for these claims.

GEOPHYSICS

Low-level helicopter borne magnetic surveys have outlined the Drybones Bay kimberlite.

The property was covered by a regional airborne survey in the 1990's and subsequently was flown in detail (Figure 6). This detailed area produced magnetic patterns consistent with the those that occur over the Drybones Bay Kimberlite and other known occurrences of Kimberlite in the Northwest Territories of Canada.

No ground geophysical magnetic surveys have confirmed the airborne anomalies.

This zone has never been investigated by drilling or till sampling.

DRILLING

No drilling on this property has been completed.

Sampling Method; Sample Preparation; Data Verification

There is reason at this stage of the property exploration to fret about these items. All the exploration to be conducted has been will be conducted according to generally accepted exploration procedures. It is inherent on all professionals to do this.

ADJACENT PROPERTIES

Exploration programs are currently being proposed by other companies for adjoining claims, but to date the Drybones Bay kimberlite is the only kimberlite body recognized in the area.

MINERAL PROCESSING ET AL; MINERAL RESOURCES ESTIMATE ET AL

The property is at too early a stage to consider these sections

OTHER RELEVANT DATA AND INFORMATION

No other relevant data and information other than that revealed in the above text is included.

CONCLUSIONS AND RECOMMENDATIONS

Consolidated Gold Win Ventures Inc. has purchased the GTEN #9 mineral claim located 50 kilometers southeast of the city of Yellowknife N.W.T. on the eastern shore of Great Slave Lake.

The property is underlain by Archean granitic rocks intruding Burwash formation sediments of the Yellowknife Supergroup. These units form part of the Slave Craton.

Airborne surveys have been conducted over the property.

The airborne geophysics indicates the possible occurrence of anomalies with affinities to anomalies associated with kimberlite pipes.

The possibility of these anomalies being kimberlite makes this a significant property of merit.

A one phase program of work consisting of ground magnetic surveys to define the magnetic anomalies outlined by the airborne survey should be undertaken. Drilling of the defined zones is recommended to evaluate the potential of the property.

Phase I which will initiate evaluation is estimated to cost $100,000.

RECOMMENDED BUDGET

Estimated Cost

Phase I:

1. Ground magnetic survey over anomalies $ 10,000

2. Till sampling $ 25,000

3. Drill testing of anomalies All inclusive - 200m $ 55,000

3. Contingencies @ 10% $ 10,000 ________

Total $ 100,000
