Commerce Resources Corp. Discovers New Carbonatites at Blue River Tantalum-Niobium Project

    VANCOUVER, Aug. 28 /CNW/ - Commerce Resources Corp. (TSXv: CCE) (FSE:
D7H) ("the Company") is pleased to announce that its regional exploration
program continues to expand the data for the Blue River Tantalum-Niobium
Project in British Columbia, and that it has located two new occurrences of
carbonatite within the Company's 500 square kilometer claim group.
    The two new carbonatites, Lower Gum Creek and Lower Switch Creek, are
located approximately 2 km east and 12 km north, respectively, of the
Company's Upper Fir Deposit. These two new carbonatites were located during
the regional exploration program, by soil geochemical surveys, which
identified extensive, continuous zones with highly anomalous concentrations of
    The Lower Gum Creek geochemical anomaly is a minimum of 1,000 meters long
and between 200 to 400 meters wide. Historic exploration within the vicinity
of the Upper Gum Creek anomaly resulted in the discovery of the Gum Creek
Carbonatite. A single grab sample was collected during a field mapping program
in 1989, and analysis of this sample returned concentrations of 3,211 g/t
Nb(2)O(5) and 75 g/t Ta(2)O(5), with highly enriched light rare earth elements
(lanthanum (La) equals 1,905 ppm; and cerium (Ce) equals 2,666 ppm). As the
area of the Upper Gum Creek soil anomaly has previously been logged, the
Company anticipates rehabilitating existing roads later this year, to
facilitate improved access for further exploration.
    The Lower Switch Creek anomaly is a minimum of 700 meters long and 50
meters wide, and was identified by soil assays, which returned values from
background concentrations to 2,354 g/t Nb(2)O(5). The Lower Switch Creek soil
anomaly continues through the historical trench location, from which historic
samples of carbonatite, collected by Anshutz Mining (Canada) Ltd., returned
values between 21 and 2,930 g/t Ta(2)O(5), and averaging 514 g/t. Depending on
weather conditions, the Company anticipates drill testing this anomaly during
    Within about 1,000 meters down slope and to the west of the Lower Gum
Creek anomaly, the Company collected a number of stream-sediment samples with
highly anomalous concentrations of niobium (Nb), yttrium (Y) and rare earth
elements (REE's), as follows:

    Note:  1 ppm equals 1 g/t
           Samples were analyzed by Acme Analytical Laboratories Ltd.
           The rare earth elements are the 15 lanthanide-series elements,
           with atomic numbers 57 to 71, which are in Group IIIA of the
           Periodic Table; they are lanthanum, cerium, praseodymium,
           neodymium, promethium, samarium, europium, gadolinium, terbium,
           dysprosium, holmium, erbium, thulium, ytterbium, and lutetium.

    These results suggest the potential presence of an as yet undiscovered
carbonatite in the area.
    In addition, the Company's ongoing regional soil and stream sediment
sampling program in conjunction with the ground geophysical surveys have
identified a potential third new carbonatite on the western slope of Mount
Cheadle, from 3 to 5 km north of the Upper Fir Deposit. Results are pending.
    "Carbonatites are very rare and unique rock types, with only
approximately 500 complexes known worldwide. Often containing a variety of
exotic minerals, carbonatites have been known to produce economic
concentrations of REE's, niobium, copper, iron, apatite, vermiculite, and
fluorite; with significant byproducts including barite, zircon, tantalum,
gold, silver, uranium and platinum group elements. Given the high ratio of
discovery to deposit, the Company remains focused on exploring for and
developing carbonatite deposits at Blue River (British Columbia), Eldor
(Quebec), and elsewhere," states Mr. Jody Dahrouge, Vice President of
Exploration of Commerce Resources.

    About Tantalum and Niobium

    Recent market fluctuations have not affected the prices of these metals,
in fact, as global demand for both metals has continued to increase, prices
have risen (
    Tantalum is the metal with the highest capacitance known, which is the
ability to hold and release instantaneously more electrical charge per gram
than any other metal. As such, tantalum is essential to most electronic
    Niobium is an additive to the production of steel, which is alloyed in to
increase strength. A 2% alloy of niobium has the ability to triple the tensile
strength of steel - from a PSI (pounds per square inch) of 40,000 to 120,000.
Niobium-alloyed steel is used in construction steel, oil and gas pipelines,
nuclear plant pipelines, the automotive industry and aerospace.

    Exploration to date at the Upper Fir deposit has outlined an indicated
resource of 8.6Mt with 208.2 g/t Ta(2)O(5) and 1,372.6 g/t Nb(2)O(5) and an
inferred resource of 5.5Mt with 208.2 g/t Ta(2)O(5) and 1,349.9 g/t Nb(2)O(5)

Verity deposit, 10 km north of the Fir property, is estimated to host an
inferred resource of 3.06Mt with 196g/t Ta(2)O(5), 646g/t Nb(2)O(5) and 3.20%
P(2)O(5) (McCrea, 2001). Detailed information on both resource estimates for
