SUMMARY
Consolidated Gold Win Ventures Inc. has acquired
by option agreement, the 6 mineral claims 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 on the adjacent property.
Airborne and limited ground magnetic surveys have
been conducted over the property and 21 holes totaling 5550 meters
have been drilled in the kimberlite body on the adjacent property.
The airborne geophysics indicates the occurrence
of two 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 6 mineral claims located 50 kilometers southeast
of the city of Yellowknife, N.W.T. on the eastern shore of Great
Slave Lake has been acquired by Consolidated Gold Win Ventures
Inc. under option agreement with New Shoshoni Ventures Ltd.
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, under laying Great Slave Lake was
not visited directly but the outcrops on the nearby islands and
mainland, where possible, were inspected between January 14 -
19, 2002.

The claims are located in Southern Mining District,
NTS Map 85 I 4, N.W.T. Co-ordinates of the centre of the property
are 62° 08¢ North Latitude, 113° 52¢ 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 claims are held under option agreement by Consolidated
Gold Win Ventures Inc. from New Shoshoni Ventures Inc. The option
agreement requires Consolidated Gold Win Ventures Inc. to make
staged cash payments of $20,000 and issue 200,000 shares of stock
and incur an exploration work expenditure of $750,000 over a seven
year period.
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.
The claims are located under the lake but its depth
is not deemed to be adverse to mineral exploration and development.
Best coverage of the property for ground geophysical
surveys and drilling of the 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
Trade Winds Resources and Southern Era) at various times during
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 of the Drybones pipe
and the total number of holes drilled on the pipe was 21 (including
the discovery hole). Processing of the drill core performed by
Ashton Mining recovered 54 diamonds of diameter >0.8 mm.
Two detailed surveys were flown over the area of
these claims.
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
213,000 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 claims is mostly under water but
numerous islands are present that have some mapped glacial features
indicate that the ice flow trended in a west south west direction.
The adjacent property contains a kimberlite body
measuring approximately 900 m by 400m in areal extent. The kimberlite
body occurs beneath a small bay near the mouth of the larger Drybones
Bay under about 38 m of water and some 67m of overburden. The
pipe intrudes grey to pale pink medium grained granite to granodiorite,
and contains xenoliths of those rocks throughout, however not
in such abundant amounts for the pipe to be termed a breccia.
Other less common xenoliths are meta-sedimentary, peridotitic,
eclogitic or granulitic.
Diamonds have been recovered throughout the adjacent
property's kimberlite body.
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.
Two anomalies with kimberlite affinities were identified
on the Consolidated Gold Win Ventures Inc.' property.
Anomaly "A" occurs in the Hump Island
area of the GSL 9 claim (Figure 6A) and anomaly "B"
is located in the Beniah Islands area of the GSL 6 claim (Figure
6B) north of an easterly trending magnetic linear (diabase dike?).
No ground geophysical magnetic surveys have confirmed the airborne
anomalies.
Both of these anomalies occur under water.
DRILLING
As described in the historical section of this report,
several drill programs have been conducted at Drybones Bay which
is adjacent to this property. A total of 21 core holes were drilled
resulting in an aggregate total meterage of 5550 meters. With
the exception of two holes, all bottomed in kimberlite. Bulk samples
of the core were sent for processing to Lakefield Research, Ashton
Mining Ltd. and De Beers.
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 on the immediately adjacent property is the only
kimberlite body recognized in the immediate area.

CONCLUSIONS
AND RECOMMENDATIONS
Consolidated Gold Win Ventures Inc. has acquired
by option agreement the GSL mineral claims 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.
A diamondiferous kimberlite occurs beneath a small
bay near the mouth of Drybones Bay on the adjacent property. Bulk
sampling of this adjacent property recovered 96 diamonds measuring
0.5 mm or greater.
Airborne surveys have been conducted over the property.
The airborne geophysics indicates the possible occurrence
of two anomalies "A" and "B" with affinities
to anomalies associated with kimberlite pipes.
The possibility of these anomalies being kimberlite
makes this a significant property of merit.
A two phased program of work consisting of ground
magnetic surveys to define the magnetic anomalies "A"
and "B" 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 "A"
