Commerce Resources Corp. Receives Resource Estimate for Upper Fir

March 05, 2007

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

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.
Present indications for the outlook for the prices of tantalum and niobium are positive as inventories continue to deplete due to the resurgence in consumer spending on electronics, and in the steel making industry. In addition, there has been increased attention put on alternate sources of tantalum due to recent market instabilities caused by the possible change of control of the world’s largest producer, Sons of Gwalia. The majority of tantalum is sold under long-term contracts. A premium is put on material derived from ‘conflict-free’ sources. Though marketing investigations have not yet been completed, tantalum concentrate reportedly sells for between $25 to $70USD/lb, while ferro-niobium sells for between $7.50 and $13.50USD/lb.

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”.
