Drilling and bulk sampling update on Mud Lake diamondiferous sill

· Issued by Big Bear Gold Corp. via CNW
VANCOUVER, April 10 /CNW/ - Consolidated Goldwin Ventures Inc. (Goldwin)
is pleased to update the activities currently underway at the Drybones 4
claim, host to the diamondiferous Mud Lake kimberlite. The project is located
approximately 55km southeast of Yellowknife, NWT. As previously announced,
Goldwin is earning a 39.6% interest in the Drybones 4 claim from Snowfield.
Upon completion of their earn in the ownership of the Drybones 4 claim will be
Snowfield 40.4%, Goldwin 39.6%, and David Smith 20%.
The focus of exploration now underway includes further delineation
drilling of the Mud Lake kimberlite complex; exploration drilling of a number
of discrete kimberlite indicator mineral trains which are coupled with
geophysical anomalies to locate more kimberlite bodies on the claim; and the
extraction of up to 500 tonnes of kimberlite for shipment to De Beers Canada
Exploration dense media separation plant located in Grande Prairie, Alberta.
The kimberlite delineation drilling is progressing on a double shift per
day basis with crews and equipment having been mobilized over the weekend of
April 8th, 2006. Titan Drilling Ltd. of Yellowknife, NWT have been contracted
to supply the crews and equipment necessary to conduct this program. A
Boyles 23 drill, currently on site and drilling adjacent to the area being
exposed for the taking of the bulk sample will also be used to conduct the
exploratory drilling on targets to the north and east of the Mud Lake
kimberlite. These targets include, but are not limited to, Pond, Sipper and
Half Moon Lakes. All kimberlite recovered will be logged and subject to
caustic fusion testing to determine the presence of macro and micro diamonds.
Following the closure of the first ice road due to adverse ice
conditions, a second ice road has now been opened closer to the shoreline on
the eastern edge of Great Slave Lake to facilitate the mobilization this week
of extra equipment to the bulk sampling project site.
The Mud Lake kimberlite is a layered sill structure currently open in
three directions. The kimberlite that is being sampled is being exposed by a
combination of trenching and removal of a granite cap. When extracted, the
kimberlite will be crushed, bagged, sealed and transported to the lake edge
for onward shipment to Grande Prairie. After processing by De Beers, the
concentrate will then be shipped to independent laboratories for the recovery
of contained diamonds. The equipment needed for this operation is either on
site or being mobilized. This includes crawler tractors, scoop trams, a Jumbo
drill and compressor, a tracked excavator and a crushing plant.
A number of soil samples previously taken are now being processed by
Overburden Drilling Management Ltd. Of Nepean, Ontario for the identification
of further kimberlite indicator minerals. The proximity of the project to the
city of Yellowknife combined with the presence of a fully winterized twenty
man camp provides great flexibility in the conduct of this comprehensive
exploration program. Further updates can be expected in a timely manner.
