Commerce Resources Corp. completed an 8,715 meter, 34-hole drilling program at its Upper Fir tantalum and niobium deposit in British Columbia to improve geological understanding. Assays from 2010 and 2011 drilling are being compiled for a resource update in Q2 2012. A preliminary economic assessment found the deposit can be developed economically as an underground mine. The company appointed a new director with experience in large-scale mine development and permitting.

1. Commerce Resources Corp. Completes 2011 Exploration Program at Upper Fir
Tantalum and Niobium Deposit, Blue River, British Columbia
Highlights:
 2011 fieldwork included approximately 8,715 metres in a 34 drill-hole definition drilling
program which was targeted to improve understanding of geological and structural
relationships within the Upper Fir deposit.
 2010 drilling results (54 holes; 12,949 metres) are currently being compiled for inclusion
in an updated three dimensional block model and resource estimate which will itself form
a separate resource update anticipated by second quarter 2012.
 Results of exploration to the end of 2010 will be described in a technical report currently
in preparation under the direction of AMEC which will provide the next milestone in the
evaluation of the Upper Fir deposit.
 Assay results from the 2011 holes remain outstanding and will be compiled for inclusion
into a separate resource update.
November 18, 2011 - Commerce Resources Corp. (TSXv: CCE, FSE: D7H) (the "Company")
is pleased to provide an update on its recently completed 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 principal focus of the Company’s work in British Columbia since
2005.
Exploration in 2011 included 8,715m of HQ-diameter diamond drilling in 34 holes largely for
purposes of infilling geological and structural information within the Upper Fir deposit.
Additional field work included core logging, assaying, down-hole geophysics, specific gravity
measurements and comprehensive re-logging of core from previous years, as well as geological
and structural mapping to test the evolving structural model. Incoming results will be compiled
for eventual inclusion into an updated resource model.
On November 3, 2011, the Company announced completion of a positive National Instrument
43-101 compliant Preliminary Economic Assessment (“PEA”) for the Upper Fir Tantalum-
Niobium Deposit. The PEA prepared by independent consultants, AMEC Americas Limited
(AMEC), indicates that the deposit can be developed economically as an underground mine and
recommends further studies to support a pre-feasibility level assessment of the project. AMEC is
a leading international consulting, engineering and project management company. A technical
report by AMEC entitled Preliminary Economic Assessment Blue River Tantalum-Niobium

2. project dated September 29, 2011, and announced on November 3, 2011, is now available on
SEDAR (http://www.sedar.com).
The economic evaluation of the PEA is based on a mineral resource estimate with the effective
date of September 29, 2011, which incorporates drilling and structural data developed from the
project to the end of 2010, including detailed solids modeling and preliminary metallurgical and
process flow sheet designs, but is based only on assay data to the end of 2009 drilling totaling
183 holes comprising 37,446 metres of HQ drill core.
The table below summarizes drilling completed in prior years:

Assays pending: Basis for subsequent

resource update (post 2Q 2012)
Drilling completed in 2011 should be considered largely as infill within the Upper Fir Deposit
but also explored known extensions of the deposit at its north end. The infill drilling was
designed to determine geological and structural relationships, and improve understanding of the
resources previously announced on February 2, 2011, which considered only drilling to the end
of 2009. As recommended by AMEC, the 2011 exploration was also completed in anticipation
of pre-feasibility requirements.
An updated block model and resource estimate with accompanying technical report under the
supervision of AMEC is currently underway using mapping and drill data from the 2010
campaign.
To avoid an undue delaying in completing this resource update while the assays and other data
from 2011 are being processed, the new data from 2011 are to be included in a second and
subsequent technical report which provides a second upcoming milestone for the Blue River
Project. Work on this technical report will begin as soon as results are received.
Other Work Completed and Ongoing in 2011
Metallurgical test work including the engineering for pilot plant design is being coordinated by
Acme Metallurgical with a view to optimizing the process design used in the PEA.
Environmental baseline investigations, including water quality, hydrology and vegetation

3. studies, which commenced in 2006, are continuing; contributing to the ongoing environmental
assessment. Additional geotechnical engineering is also underway.
The Blue River Project is wholly owned by Commerce and encompasses 105,373 hectares (about
1,050 km2). Power transmission lines, rail, and paved and gravel roads are all adjacent or within
the property boundaries. Transalta Corp.'s 18 MW Bone Creek run-of-river hydroelectricity
project was recently completed near the project and began production in April 2011.
The Upper Fir deposit is one of over 25 carbonatite occurrences on the project. Indicated mineral
resources total 36.35 million tonnes containing 195 ppm Ta2O5 and 1,700 ppm Nb2O5 and
Inferred mineral resources total 6.40 million tonnes containing 199 ppm Ta2O5 and 1,890 ppm
Nb2O5. The mineral resource estimate is supported by a base case price assumption of
US$317/kg Ta metal in an oxide product and $US46/kg niobium metal in an oxide product.
Sufficient working capital is available to complete all of the Company’s development and
exploration plans for Blue River.
