Commerce Resources Corp. (TSXv: CCE) (FSE: D7H) (“Commerce”) is pleased to announce a resource estimate for its Upper Fir Carbonatite located in eastern British Columbia.
The new resource estimate has been prepared based on 20 drill holes completed during 2005 and 2006. The holes outlined a series of sill-like bodies with up to 100 m total thickness, and which extend for more than 750 m in a north-south direction and up to 300 m in an east-west direction. The Upper Fir Carbonatite appears to thicken to the east and to the south, and remains open in both of these directions.
The new resources are as follows:
INDICATED RESOURCES ------------------------------------------------------------------------- Tonnes (greater than) Grade Contained lbs (Kilograms) Cut Off Cutoff Ta(2)O(5) Nb(2)O(5) (Millions) g/t Ta (tonnes) g/t g/t Ta(2)O(5) Nb(2)O(5) ------------------------------------------------------------------------- 100 23,100,000 177.0 1,144.8 9.00 (4.09 kg) 58.27 (26.49 kg) 150 8,600,000 208.9 1,372.6 3.98 (1.81 kg) 26.16 (11.89 kg) ------------------------------------------------------------------------- INFERRED RESOURCES ------------------------------------------------------------------------- Tonnes (greater than) Grade Contained lbs (Kilograms) Cut Off Cutoff Ta(2)O(5) Nb(2)O(5) (Millions) g/t Ta (tonnes) g/t g/t Ta(2)O(5) Nb(2)O(5) ------------------------------------------------------------------------- 100 13,300,000 178.4 1,149.0 5.25 (2.39 kg) 33.72 (15.33 kg) 150 5,500,000 208.2 1,349.9 2.51 (1.14 kg) 16.3 (7.41 kg) ------------------------------------------------------------------------- Notes: - Mineral resources which are not mineral reserves do not have demonstrated economic viability. - Not all tonnage will be recovered in mining, nor will all metal be recovered during milling and processing.The mineral resource estimations have been prepared by John Gorham, P.Geol., in accordance with the Standards of Disclosure for Mineral Projects as defined by National Instrument 43-101 (NI 43-101). John Gorham, P. Geol. is an independent Qualified Person as defined by NI 43-101.
- From a solid model mineral resources were estimated using ordinary kriging and a block model with 5 x 10 x 10 m blocks.
- A specific gravity of 3.00 was utilized in converting volume to tonnes.
- Indicated resources are those resources within 75 m of an existing data point, while inferred resources are those resources that are between 75 m and 100 m of an existing data point.
J. Gorham, P.Geol., strongly recommends an exploration and infill diamond drill program to upgrade the existing resource base and to continue to expand upon the deposit to the south and east. The 2007 drill program is expected to commence in spring 2007.
“We are pleased to receive these extremely encouraging results regarding the near surface Upper Fir Carbonatite and its increasing potential,” states President David Hodge. “We look forward to further defining and upgrading the resource estimates”.

The NI 43-101 Technical Report will be posted on the Company website and on SEDAR within a 45 day period following this news release. All other information previously released on the Upper Fir Carbonatite is available on the Company’s website.
