COMMERCE RESOURCES CORP. ANNOUNCES SIGNIFICANT TANTALUM POTENTIAL IDENTIFIED AT UPPER FIR CARBONATITE
Commerce Resources Corp. is providing the following update on its 2006 exploration program at the Upper Fir carbonatite, located on its wholly owned Blue River property, in east-central British Columbia.
During 2005 and 2006, Commerce completed two drill programs. The first was designed to confirm the economic potential of the Upper Fir carbonatite, and the latter to define its extent, grade and thickness, in order that the company may complete a resource estimate for this near-surface, tantalum-niobium occurrence. Both programs achieved their stated goals, while the latter only partially defined the limits of the carbonatite body, owing primarily to the greater-than-expected thicknesses, strike length and width for this intrusive body. The company has commissioned an independent NI 43-101 compliant resource estimate to be completed for the Upper Fir carbonatite.
In total, 21 holes have been completed, four during the fall of 2005 and 17 during the summer/fall of 2006. The company is now in receipt of assay results from the 17 drill holes completed during 2006. Results for the drill holes are summarized in the following table, while additional information (such as a location map) is provided on the company's website. Essentially, 20 of the 21 holes intersected carbonatite host rock and were completed within an area measuring 750 metres north-south, by 200 m east-west. Drilled thickness varied from 8.77 m to 95.70 m. In some cases, the drilled thickness may exceed the true thickness by 10 to 15 per cent, owing to the interpreted shallow east dip of the carbonatite, and the orientation of the drill holes. Average grades of carbonatite for the 17 holes completed in 2006, range from 147 to 237 grams per tonne Ta(2)O5, and 567 to 1,941 g/t Nb(2)O5.
Results for drill holes CF-06-01 to CF-06-17, completed during 2006, are summarized in the accompanying table.

New exploration potential for the Upper Fir
The explored portion of the Upper Fir carbonatite is interpreted to represent a network of multiple lens-like bodies that dip gently to the south and east. The complex appears to thin to the north, with the greatest continuous thickness of a single carbonatite body yet intersected (83.05 m within hole CF-06-15) being located within the southernmost fence of the drill holes. Adjacent to the east of CF-06-15, hole CF-06-16 intersected a total of 83.14 m of carbonatite, with two thin xenoliths of country rock.
The thickness of carbonatite intersected in these two drill holes is significant because:
1) it opens the exploration potential for additional, significant tonnages of carbonatite, to the south and east;
2) the near-surface nature of the deposit would support an open pit mining scenario;
3) the overall ratios of Nb/Ta appear to decrease from north (six to eight) to South (three to four);
4) the tantalum grades are nearly constant; and
5) the mineralogy of the carbonatite and its ore minerals may change from north to south.
Based on the drilled intersections and the geochemistry, the northern portions of the Upper Fir carbonatite may represent the peripheral and more differentiated portion of the intrusion, while the thicker, southernmost portions are more primitive. Hence, if the Upper Fir carbonatite is a part of a very large intrusion, it is likely centered near holes CF-06-15 and CF-06-16 and to the southeast of the explored area. Also, evidence to date indicates that the overall chemistry of this centre may be similar to that of carbonatite in holes 15 and 16, where relatively high grades of tantalum, but generally lower overall ratios of Nb/Ta were observed.
Dave Hodge, president of Commerce, commented: "In 2006, for the first time, we have established significant tonnage potential at the Upper Fir. Drilling to date suggests that the tantalum- and niobium-bearing carbonatite, intersected in numerous locations over a 750-metre-by-200-metre area, and up to 105.87 m in thickness, may comprise part of a contiguous system, lending strong support for the overall economic potential of the project, not to mention the fact that the deposit is accessible from surface."
Jody Dahrouge, PGeol, and director, a qualified person as defined by National Instrument 43-101, supervised the preparation of the technical information in this release. Except as noted above, all samples were analyzed at Acme Analytical Laboratories in Vancouver, B.C., using ICP-MS.
