Commerce Resources Corp. (TSXv: CCE, FSE: D7H, OTCQX: CMRZF) reports the assay results for the first four of seven drill holes completed during the 2011 winter drilling program at the Ashram Rare Earth Element (“REE”) Zone at the Company’s Eldor Project in northern Quebec.

1. Commerce Resources Corp. Drills 2.10% TREO over 586.92 metres including
3.00% TREO over 36.99 metres at the Eldor Property, Quebec
June 28, 2011 - Commerce Resources Corp. (TSXv: CCE, FSE: D7H, OTCQX: CMRZF) (the
“Company” or “Commerce”) is pleased to report the assay results for the first four of seven drill
holes completed during the 2011 winter drilling program at the Ashram Rare Earth Element
(“REE”) Zone at the Company’s Eldor Project in northern Quebec.
The thickness and north-south extent of the REE mineralization at the Ashram Zone has been
significantly expanded by this set of drill holes. The highlight is EC11-048 which intersected
REE mineralized carbonatite over its entire length returning 2.10% Total Rare Earth Oxides
(“TREO”) over 586.92 metres including 36.99 metres of 3.00% TREO. EC11-048 is the best
hole reported to date in terms of grade and thickness with seven sample intervals returning
greater than 4% TREO to a peak value of 9.88% TREO. The hole ended in mineralization as the
depth limitations of the drill were reached.
Further results from holes EC11-048, 49, 50 and 51 are included in the table below:

*All samples were analyzed by Activation Laboratories of Ancaster, ON using its method eight -- major oxide, rare
earths and trace element package by fusion ICP and ICP/MS in addition to niobium by XRF, and fluorine by method
4F-F. The four most abundant REEs that make up the TREO reported above are cerium, lanthanum / neodymium
and praseodymium.

2. As the deposits geometry is still being determined actual drill widths are unknown but are
estimated to be near to true thickness.
These step-out holes have expanded the REE mineralization at Ashram by 150 metres to the
northeast and extended the depth of known mineralization by 235 metres from 365 metres to
approximately 600 metres. REE mineralization at the Ashram has now been defined over an area
measuring in excess of 600 metres east-west, by 500 metres north-south, to depths in excess of
600 metres. The mineralization remains open to the north, south, east, at depth, and is not fully
constrained to the west.
Eight holes totaling 3,656 metres were completed during the winter program. Seven of the holes
(3,367 metres) were drilled at the Ashram Zone and were vertically collared on Centre Pond to
test the northern, eastern, and depth extensions of the Ashram Deposit. The final hole of the
program was drilled at a separate location approximately 1 kilometre north of Ashram known as
the Triple D Target. Assay results for the remaining four holes (EC11-052, 053, 054, and 055) are
pending. A total of 6,680 metres of drilling has now been completed at the Ashram Zone over 19
holes.
A map showing the location of drill holes, along with detailed analytical results, will be posted
on the Company’s website at: http://www.commerceresources.com/s/Eldor.asp
The deposit continues to display increased grade moving north as well as enrichment in the
middle and heavy rare earth elements. As drilling has progressed northward drill intersections of
greater than 3% TREO have increased in occurrence with 4% TREO assays becoming more
common. Zones of enrichment in the middle and heavy rare earth oxides (“MHREO”) as well as
neodymium oxide (“Nd2O3”) continue to be encountered. EC11-050 returned 11.4% MHREO
and 22.5% Nd2O3 over 34.69 metres at 1.46% TREO (238.42 – 273.11 metres) as well as 13.6%
MHREO and 19.6% Nd2O3 over 72.13 metres at 1.23% TREO (305.65 – 377.78 metres). The
MHREO values are significant compared to the already anomalously high average for the
Ashram Deposit of 7.4% MHREO. Neodymium enrichment is prevalent in the drill holes as
well. For example, EC11-051 intersected 22.7% MHREO and 31.5% Nd2O3 over 14.53 metres at
0.83% TREO (500.41 – 514.94 metres) in addition to numerous other similar intersections up
hole.
Currently, two types of MHREO enriched zones are apparent in the deposit. The first is a ferro-
carbonatite of approximately 1.20-1.45% TREO that averages 12-20% MHREO with high
fluorite content and xenotime-(Dy) as the main REE bearing phase (e.g. EC11-047). The second,
is a magnesio-carbonatite of approximately 0.80-1.00% TREO that averages 10-15% MHREO
with low fluorite content and courser grained rare earth fluorocarbonates (bastnaesite, parisite,
and synchysite) as the main REE bearing phase. The geometry of the enriched zones is still not
well constrained, however, both appear to be extensive with the first being closer to the centre of
the deposit and the later potentially forming an enriched outer halo around the deposit. Increased

3. enrichment in neodymium oxide is commonly associated with increased MHREO in both
settings.
The Ashram Deposit is a large tonnage rare earth discovery and is ranked as one of the largest
rare earth deposits outside of China. In early 2011, Commerce reported an initial NI 43-101
resource estimate for the Ashram Zone of 117.34 million tonnes averaging 1.74% TREO in the
Inferred Category using a base case cutoff of 1.25% TREO (SGS Geostat, April 2011). The
resource estimate was based on twelve holes totaling 3,313 metres drilled in 2010.
Preliminary mineralogical work completed by Roger Mitchell of Lakehead University, ON has
indicated that monazite-(Ce) along with lesser bastnaesite-(Ce) and trace amounts of xenotime-
(Dy) and nioboaeschynite-(Dy) are the main REE bearing minerals at the Ashram. Areas of
enrichment in the middle and heavy rare earth elements are marked by an increase in xenotime-
(Dy), which is a dominantly heavy rare earth bearing mineral, and/or a decrease is monazite-
(Ce).
Hazen Research Inc. of Golden, Colorado is conducting preliminary metallurgical work on
material from the 2010 drilling program. Commerce will also be continuing exploration and
drilling through the spring and summer in combination with the metallurgical work with the aim
to collect the data necessary to complete a Preliminary Economic Assessment for the Ashram
Deposit. Details of the spring and summer work program will be provided upon receipt of the
final assays from the winter program.
The Eldor Property is located in northern Quebec approximately 130 kilometres south of the
