Metalex Ventures Ltd. - Gold, copper and uranium anomalies discovered in Quebec

LOWNA, BC, Aug. 29 /CNW/ - Metalex Ventures Ltd (MTX-TSX Venture
Exchange)("Metalex" or the "Company").
Metalex, Wemindji Exploration Inc and Dianor Resources Inc, collectively
called the Quebec Joint Venture, have collected 1069 reconnaissance drainage
and till samples over an area of 360,000 km(2) in Quebec. In addition to
analysis for diamond indicator minerals, which has been previously reported,
the heavy mineral concentrates were also geochemically analyzed for copper,
cobalt, nickel, silver, zinc and molybdenum by atomic absorption and for gold,
silver, arsenic, barium, bromine, calcium, cobalt, chromium, cesium, iron,
hafnium, mercury, iridium, molybdenum, sodium, nickel, rubidium, antimony,
scandium, selenium, strontium, tantalum, thorium, uranium, tungsten, zinc and
eight rare earth elements by neutron activation.
Whilst anomalous concentrations of 28 metals have been found in the heavy
mineral concentrates, this press release will focus on the results for gold
and its pathfinder elements; copper - nickel - cobalt; and uranium as these
commodities are high demand right now.
Anomalous gold concentrations have been found in more than 400 samples.
Seventy-four samples contain gold values between from 7,700 to 66,300 parts
per billion ("ppb")(7.7 to 66.3 g/t). When compared with the upper limit of
the range of background values of 60 ppb (the threshold value) these 74
samples are classified as "exceptionally anomalous." About 1/3 of the
exceptionally anomalous samples contain anomalous amounts of silver, antimony
plus/minus arsenic. This anomalous metal association suggests that the gold in
these samples is derived from hard rock (not placer) sources. Whilst several
of the exceptionally anomalous samples occur down ice, or close to, known gold
deposits, most of them are unexplained and are thought to be derived from
undiscovered mineralization.
Anomalous copper values have been found in 109 samples. Seventeen samples
contain copper values between 120 to 374 parts per million ("ppm"). When
compared with a threshold value of 40 ppm, these samples are classified as
"strongly anomalous". One additional sample contains 3.36 percent copper and
is exceptionally anomalous. Eleven of these latter 18 samples also contain
anomalous cobalt values and two contain anomalous nickel values suggesting
that some of the anomalous values may be derived from copper - nickel - cobalt
mineralization. Apart from the exceptionally anomalous value, which is located
in an area of known copper mineralization, the 17 strongly anomalous are
unexplained and may reflect undiscovered mineralization.
Anomalous uranium values occur in 173 samples. Twenty-seven samples
contain uranium values between 336 to 996 ppm. When compared with the
threshold value of 165 ppm, these 27 samples are classified as strongly
anomalous. These strongly anomalous samples are accompanied by anomalous lead
(121 - 2870 ppm) in twenty samples and thorium (5,000 - 14,900 ppm) in
thirteen samples. The association of uranium and lead may point to Proterozoic
or Archaean age uranium deposits. None of the strongly anomalous samples
appear to be derived from known uranium occurrences and they are thought to
reflect undiscovered mineralization.
Given that the Archaean shield of eastern Canada contains a number of
world-class metal mines, e.g. gold in the Val d'Or region of Quebec, nickel -
copper - cobalt at Sudbury and Voisey Bay, and Uranium at Blind River, the
geochemical results obtained above are regarded as most encouraging;
particularly since they are spread throughout the regional area. An initial
follow up program of approximately 500 samples is to be carried out to locate
and prioritize the provenance area and sources of the anomalous metal values.
This work will be in addition to the follow up program planned to trace
discovered diamond indictor minerals to their source.
An agreement was recently executed between the Quebec Joint Venture
parties and Blustone Minerals Inc. Under this agreement Blustone will fund   
$2 million of exploration expenditures by July, 2007 to earn a 19% interest in
the Quebec Joint Venture. Upon Blustone earning its 19% interest, the interest
of Metalex in the Quebec Joint Venture will be 27%. If Blustone fails to spend
C$2 million it will be deemed to have withdrawn with no interest.
The Company is most encouraged by the results in Quebec to date. Diamond
indicator minerals have been found and are being followed up. Exceptionally
anomalous geochemical gold values and strongly anomalous copper and uranium
values could lead to the discovery of new gold, copper - nickel - cobalt and
uranium deposits respectively. The agreement with Blustone spreads the
Company's risk and allows an expansion of its exploration program.
