       Upper Fir Tantalum-Niobium Deposit, under the supervision of AMEC,
       Vancouver is underway. The completed study is expected to be delivered
       to the Company in the fourth quarter of 2010;

    -  2010 fieldwork has begun; a 10,000 meter (30-40 hole) definition
       drilling program is planned to determine geological relationships and
       upgrade the classification of resources; and

    -  Results from the 2009 drill program (22 holes; 5,587 meters) are
       anticipated to be received shortly and are expected to be included in

Commerce Resources Corp. (TSXv: CCE, FSE: D7H) (the "Company") is pleased to provide an update on the planned and ongoing exploration and development activities for the Company's wholly owned Blue River Project, east-central British Columbia. The Blue River Property is host to the Upper Fir Tantalum and Niobium Deposit, which was discovered in 2002 and which has been the focus of the Company since 2005.

During 2010, the Company plans to complete approximately 10,000 meters (30 to 40 holes) of HQ diamond drilling, largely as infill within the Upper Fir Deposit. The purpose of the infill drilling is to determine geological relationships and upgrade the classification of resources previously announced on March 31, 2010 as recommended by Dr. Michelle Stone of Caracle Creek International Consulting (CCIC) and in anticipation of pre-feasibility requirements.

In parallel with the exploration work, a Preliminary Economic Assessment (PEA) of the Upper Fir Deposit, under the supervision of AMEC, Vancouver, is underway. The assessment will incorporate all data developed from the project to date, and include, detailed solids modeling and preliminary metallurgical and process flow sheet designs. It is expected that AMEC will deliver the completed study to the Company in the fourth quarter of 2010.

Klohn Crippen Berger Ltd., Vancouver, completed a review of potential waste rock and tailings sites in 2009, with additional assessment continuing by AMEC. Environmental data collection first initiated in 2006 is ongoing. This will ensure that the Company develops a solid baseline of environmental data in support of project development.

In 2009, Commerce completed 22 infill and step-out exploration holes (totaling 5,587 meters) at the Upper Fir Deposit, adding to the previous 153 holes completed between 2005 and 2008 (totaling 30,648 meters). The most recent resource estimate announced March 31, 2010, did not include results from the 2009 drill program. The 2009 drill results will be included in an updated geologic model as part of the ongoing PEA.

The Blue River Project is wholly owned by Commerce and encompasses approximately 1,000 km2 of mineral claims located 25 to 60 km north and northeast of Blue River, British Columbia. Infrastructure surrounding the project is excellent with BC Highway 5 crossing the claims along with rail, power, and a water supply.

The Upper Fir Deposit is one of several carbonatite occurrences on the Project and at a 175 grams per tonne ("g/t") Ta2O5 cut-off contains an Indicated Resource of 7,384,000 tonnes with a grade of 217 g/t Ta2O5 and 1,202 g/t Nb2O5 (3,533,000 and 19,568,000 lbs of contained Ta2O5 and Nb2O5, respectively). Inferred Resources at the same cut-off include 16,494,000t of 213 g/t Ta2O5 and 1,222 g/t Nb2O5 (7,746,000 and 44,436,000 lbs of contained Ta2O5 and Nb2O5, respectively (Stone & Selway, 2010).

Sufficient working capital is available to complete all of the Company's development and exploration plans. As at April 30th, 2010, the Company had $19.8 million in cash and investments.
