VANCOUVER, Nov. 27 /CNW/ - Copper Ridge Explorations Inc. ("Copper Ridge"
or the "Company") announces the final results of the exploration programs
conducted on its Borealis Uranium Project located northeast of Dawson City in
the Yukon. A 1,108 kilometre airborne radiometric and magnetic survey
successfully defined a large area of anomalously high uranium both within and
fringing the Deadman intrusive body (see attached map). Follow-up prospecting
and silt, soil and rock sampling confirmed previous results and identified
several targets for additional follow-up.
The Borealis property covers approximately 3,550 hectares of the Deadman
Stock, a mid Cretaceous multiphase granitic unit of the Tombstone Suite
intrusive complex. Uranium mineralization is associated with a late stage
phase of syenite dykes within the stock and occurs as structurally controlled
lenses of pitchblende and as disseminations of uraninite within the syenite.
The property was discovered in the 1970's by Chevron Minerals following a
program of reconnaissance airborne surveying and stream sediment sampling.
Follow-up prospecting discovered several areas of float and outcrop in the
stock with significant uranium mineralization. In one area, 24 samples taken
from a 10 by 60 m talus train returned values ranging from 38 to 4200 ppm U
and averaging 2100 ppm U (0.21%). A sample of angular float from another area
returned a value of 9.7 % U(3)O(8).
The airborne survey was successful in defining a much larger area of
anomalously high uranium than was previously recognized. Based on the results
of the survey, Copper Ridge has staked an additional 80 claims to cover
anomalous rocks that were outside of the initial 92 unit claim block.
The soil and silt sampling programs were focused on evaluating a small
portion of the larger radiometric anomaly defined by the airborne survey and
were successful in identifying several areas for detailed follow-up in 2008.
Eighteen of the 36 silt samples collected exceeded the 90th percentile value
of 10 ppm uranium for silt samples in the Selwyn Basin as determined by
regional programs conducted by the Yukon government. Two samples, returning 29
and 93 ppm uranium, exceeded the 99th percentile value of 28 ppm.
The rock sampling program served to confirm the uranium mineralization
previously discovered by Chevron. Of 21 samples collected in the known showing
areas, 11 returned values greater than 0.05 % (500 ppm) uranium. The results
of these 11 samples are shown in the table below:
Sample Type U (%) U ppm
36451 Grab 0.113 greater than 1000
36452 Grab 0.106 greater than 1000
36454 Grab 597.6
36455 Grab 0.222 greater than 1000
36456 Grab 115.8
36457 Grab 162.3
36458 Grab 0.184 greater than 1000
36459 Grab 2.080 greater than 1000
36460 Grab 0.118 greater than 1000
576553 Grab 0.158 1752.0
576554 Grab 0.243 greater than 2000.0
576563 Grab 875.9
576565 Grab 0.114 1248.0
In addition, limited prospecting in areas of high uranium background
returned two grab samples which reported values of 236 and 154 ppm uranium.
The area where these samples were taken was not previously known to host
uranium mineralization and is high priority follow-up target for 2008.
The positive exploration results for the 2007 season confirm that
anomalous uranium mineralization occurs over a large area on the Borealis
Project. The results set the stage for an aggressive program of exploration in
2008 which will include more detailed soil and silt sampling, intensive
prospecting, geologic mapping and trenching. Contingent on success, the
results of these programs will be used to guide a drilling program.
The airborne survey was carried out by Aeroquest International Ltd. and
assays were completed by Acme Analytical Laboratories. Mr. J. Greg Dawson,
P.Geo., Vice President of Exploration for Copper Ridge, supervised the
exploration program, is the Qualified Person for the Borealis project and is
responsible for the technical content of this news release.
Copper Ridge's exploration philosophy focuses on maximizing the potential
for success in a high-risk business. With grass roots mineral exploration,
where the entry cost is low but the potential reward can be very high, success
will be contingent on exploration skill and on carefully managed risk. Our
management team brings tenacity, technical skill and experience, all crucial
ingredients for discovery. By exploring a broad array of projects, focusing on
the right commodities, in areas of high mineral potential, in mining-friendly
jurisdictions and by sharing the risks on some projects with joint venture
partners, Copper Ridge is exposing its shareholders to a greater chance for
discovery. The Company is nearing completion of an active field program on its
Yukon and British Columbia properties.
