Commerce Resources Corp. Expands Rare Earth Element Mineralization at Eldor

December 21, 2009 – Commerce Resources Corp. (TSXv: CCE) (FSE: D7H) (the “Company” or “Commerce”) is pleased to report that sampling has identified additional rare earth element mineralization (REE) within the newly discovered Ashram Zone at the Eldor Project, northern Quebec.

The Ashram Zone was discovered in 2009 by tracing the source of a glacially dispersed boulder train that assayed significant REE. The zone is located near the centre of the Eldor Carbonatite complex, and is coincident with a magnetic low approximately 1 kilometre by 0.8 kilometres in size.

A total of 70 rock samples were collected as follow-up to the discovery made during the 2009 summer exploration program. A high value of 2.74% REE was returned from exposed outcrop, with values in excess of 1% REE representing over 55% of the total rock samples collected (boulders and outcrop).

Significant mineralization (>1% to 2.74% REE) was consistently returned from numerous samples over multiple outcrops within an area measuring approximately 500 metres by 150 metres, truncated to the east by a shallow lake. Sample lithology is consistently moderately radioactive, very fine grained to massive, grey-green carbonatite, with variable amounts of fluorite and disseminated pyrite.

REE distribution is dominantly light rare earth enriched (Ce, La, Nd and Pr), however, several samples show a flatter distribution indicative of a relative enrichment in the heavy REE. Preliminary thin section work by Roger Mitchell of Almaz Petrology has identified several REE bearing minerals as common sources of REE mineralization. These include the REE fluorocarbonates bastnaesite (Ce,La,…)CO3F, synchysite Ca(Ce,La,…)(CO3)2F and parasite Ca(Ce,La,…)2(CO3)F2 as well as the minerals aeschynite (Nd,Ce,Y,Ca)(Ti,Nb)2(O,OH)6 and monazite (Ce,La,..)PO4.

During the fall program, sampling was also conducted at a tantalum-niobium target, the “Glimmerite Occurrence,” originally identified in 2007, located 1.5 kilometres north of the Ashram Zone. Significant tantalum-niobium mineralization was confirmed with a sample assaying 1682 ppm tantalum and exceeding the detection limit for niobium (greater than 50,000 ppm (5%) Nb). Further work is required to fully assess the zone’s significance and extent.

Given the success of the reconnaissance work at Eldor, Commerce intends to significantly expand the scope of exploration in 2010. It is anticipated that next years’ program will include prospecting, mapping, and drilling at the Ashram Rare Earth Zone as well as further exploration at the tantalum-niobium targets developed during the 2008 drilling program. In addition, the 2007 airborne radiometric and magnetic survey is currently being re-interpreted, by Rob Shives of GamX Inc., to examine the significance of the magnetic low that marks the Ashram Zone as well as other priority targets.

The Eldor Property is located in northern Quebec, approximately 130 km south of the town of Kuujjuaq. The property is 100% owned by Commerce and now encompasses 404 claims comprising approximately 18,886 hectares. Additional ground was recently acquired, adjacent to the south and east of the property, to cover anomalies identified from prospecting and soil sampling.

The Eldor property hosts several mineralized zones including the Ashram Rare Earth Zone as well as the Northwest, Southeast and Star Trench zones where previous drilling has identified significant concentrations of tantalum and niobium as well as appreciable amount of uranium, phosphate and fluorine. Geologically, the Eldor Project is a large carbonatite complex. Carbonatites and carbonatite related deposits are a major host for rare metals, such as niobium and tantalum, and rare earth elements. The world’s largest niobium mine, Araxa in Brazil, and several of the world’s largest rare earth element deposits, including Mt. Weld in Australia, and Mountain Pass in the United States, are all hosted by carbonatites.
