VANCOUVER, March 27, 2013


  *Mineralogical variability studies show that the composites tested achieved
    similar recoveries (i.e. both by weight and grades of niobium and
    tantalum) to the partially optimized rougher flotation process established
    during the previous phase 1 and 2 metallurgical programs.

  *Over 90% of the composites tested achieved rougher recoveries which
    exceeded 96% tantalum and 92% niobium within the tantalum/niobium circuit

  *The amount of tantalum and niobium metals reporting to the flotation feed
    is relatively constant at about 81.4% for tantalum and 80.6% for niobium

  *The Mineral Resource update underway at AMEC will include results of
    exploration in 2012, as well as 34 drill holes (totalling 8,715 m) of
    infill drilling completed in 2011 and not included in the previous

VANCOUVER, March 27, 2013 /PRNewswire/ - Commerce Resources Corp. (TSXv: CCE,
FSE: D7H, OTCQX: CMRZF) (the "Company" or "Commerce") is pleased to provide a
further update on recent work completed at its Blue River Project since
release of the National Instrument (NI) 43-101 compliant Mineral Resource
update (Commerce news release July 6, 2012) for the Upper Fir Deposit. Newly
completed mineralogical variability studies show that the partially optimized
flotation flow sheet which formed the base of the metallurgical analysis in
the Preliminary Economic Assessment (Commerce news release November 3, 2011),
and which was further optimized during Phase 2 test work (reported December 3,
3012) shows good applicability across the range of mineralogies tested.

The geological, engineering, metallurgical and environmental programs  carried 
out in  2012 provide  broad  support to  the  advancement of  exploration  and 
development at the  Company's wholly  owned Blue  River Project,  east-central 
British Columbia. The  new metallurgical  results continue  to strengthen  the 
foundation of broadly based technical  knowledge developed in 2012, and  after 
completion of the mineral resource update currently in progress by independent
consultants AMEC Americas  Ltd. ("AMEC"),  will be sufficient  to support  the 
initiation of a pre-feasibility study (PFS).

"We are pleased with these new results from what has been a significant amount
of work accomplished  in the  past year. These  metallurgical results  provide 
additional upside to the positive test work previously reported in the PEA,  a 
major milestone  in our  progress  to develop  the  Upper Fir.  The  post-PEA 
metallurgical results reinforce Commerce's belief  that we are in the  process 
of building a  very important long-term  source of conflict  free and  ethical 
tantalum which could potentially supply 10% of the current world's market  for 
the long term." says Dave Hodge,  Commerce's President. "We will be  extremely 
interested in the upcoming  resource update from AMEC  which will be based  on 
all work to date."

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's 
activities since 2005. In  fiscal 2012 Commerce  spent approximately $3.8M  on 
the Property.

Metallurgical Test Work in 2012
Metallurgical work in 2012  has continued to update  and optimize the  process 
flow  sheet  described  in  the  NI  43-101  compliant  Preliminary   Economic 
Assessment  ("PEA")  study  completed  by  AMEC  on  the  Blue  River  Project 
(effective date of September 29, 2011;  see Commerce news release of  November 
3, 2011). The process flow sheet for the recovery of the tantalum and niobium
described in the PEA was developed in 2011 based on Phase 1 studies.

In April 2012, Commerce  commissioned Acme Metallurgical  Ltd ("Acme Met")  of 
Vancouver, BC  to initiate  a  Phase 2  investigation.  This was  designed  to 
follow-up the  successful results  of  the earlier  program which  had  tested 
flotation as the preferred method to remove the larger portion of fine  slimes 
and carbonatite minerals early in the process. Subsequent process steps  could 
then focus on material containing Ta and Nb.

Phase 2  testing  optimized  the  use of  desliming  and  carbonate  rejection 
flotation, as well as chemical reagent  dosages to increase the efficiency  of 
rougher/cleaner Ta/Nb flotation. This work enabled finalization of the process
flow sheet developed in Phase 1 which was based on composite samples BS-2F and
BS 2G. All Phase 2 work was  conducted on these same composites and all  tests 
were conducted at a grind size of 80% passing 130 microns. These results  were 
reported in a news release dated the 3^rd of December 2012.

Mineralogical Variability Testing
A total of 767 samples of drill  core rejects from the Upper Fir deposit  were 
combined into thirty-six composites (selected to represent five different  end 
member mineralogies within  the deposit) and  subjected to flotation  testing. 
This variability testing,  initiated in  April 2012 and  completed in  January 
2013, had the primary objective of determining the composites' response to the
partially optimized flotation procedure established  during the Phase 1 and  2 
metallurgical programs completed in 2011 and 2012 and previously reported.

Key Areas of Variability Investigation and Results:

Desliming and Mass Rejection

  *The majority of the composites are amenable to the standard one stage
    cyclone desliming process with rejection of 17.2% of the weight as slimes,
    containing 7.2% of the tantalum and 6.9% of the niobium. Variation of the
    weight rejected is minimal between composites with no significant effect
    from grind sizes or mineralogy.
  *The total carbonate mass rejection is proportional to the amount of
    carbonate and phosphate materials in the feed, with the average weight of
    carbonate concentrate floated and rejected for all composites being 53.2%
    of the mass, with losses of 11.4% for tantalum and 12.5% of niobium.
    Metals losses were directly proportional to the weight of concentrate
    removed and independent of head grades.

Carbonate Concentrate Cleaning

  *Cleaning of the carbonate concentrate was not performed during this
    testing campaign, however, the scavenger stage of flotation represented
    about 40% of the total weight floated, containing about two thirds of the
    metal losses. This is indicative of mechanical losses due to strong
    scavenging action and entrainment.
  *It is strongly recommended that cleaning of the concentrate be kept in the
    flow sheet to reduce these losses. Recycling the cleaner tails to the
    Ta:Nb flotation feed might account for 2% to 6% of the metals in the feed.

Feed to Tantalum:Niobium Flotation

  *Though the weight of material left after slimes and carbonate removal does
    vary with the type of mineralogy, it overall averages 29.5%. The amount of
    metals reporting to Ta:Nb flotation nevertheless remains fairly constant
    at about 81.4% for tantalum and 80.6% for niobium. Losses of metals to
    that point are proportional to the weights removed and thus statistically
    inversely proportional to head grades.
  *Within the Ta:Nb rougher and cleaner flotation circuit only, over 90% of
    the composites achieved rougher grade Ta:Nb recoveries which exceeded 96%
    for Ta and 92% for Nb.

Magnetic Separation

  *The final stage of magnetic separation also increased the final
    concentrate grade with minimal loss of the Ta and Nb minerals. This
    supports results from Phase 2 work in which approximately 50% of the final
    concentrate mass was removed with minimal Ta/Nb loss.

Acme Metallurgical Recommendations
Acme Met recommends that further optimization work be undertaken as follows:

  *The carbonate flotation stage appears to require a lower dosage of the
    oleic acid collector as tantalum and niobium minerals are likely trapped
    and entrained with the tight froth generated by the over dosage of oleic
  *The balance of flotation reagents diamine acetate (Duomac T- as collector)
    and fluosilicic acid (H[2]SiF[6] as pH modifier/silicates depressant) in
    the Ta:Nb cleaning circuit should be investigated as metals losses are
    mostly observed between pH 4 to 3.
  *A fifth and sixth stage of cleaning should be investigated to achieve a
    grade of 35% combined Nb-Ta oxides.
  *Locked cycle tests should be completed to provide clear indication of
    reagents consumption as each stage.
  *Full assaying of final concentrate products, particularly for sulphur and
    rock-forming elements, could provide additional information which would
    help orient further investigations.

Upcoming Mineral Resource Update
A Mineral Resource Update and subsequent technical report which will
incorporate all data from 2005 through 2012 is currently underway by AMEC with
completion targeted for the second quarter of 2013. This work will build from
the previous Mineral Resource Update technical report (effective date June 22,
2012) in which AMEC compared results from the 34 holes totalling 8,715m
drilled in 2011, after the closure of the resource database to the updated
resource model and found them to be reasonably consistent with the geology
predicted by the model.

2011 PEA Outcomes
The Preliminary Economic Assessment ("PEA) was prepared to define an overall
proof of concept for further development of the Blue River Project. The PEA
(effective date September 29, 2011) indicated that the deposit can be
developed economically as an underground mine and recommended future studies
to support a pre-feasibility level assessment of the project. The assessment
included geological and mineral resource modeling, preliminary mine planning,
a description of metallurgical test work and process design, a summary of
environmental baseline work to date, and estimates for capital and operating
costs. As well, it determined the economics to develop the project as an
underground mine with process facility, and included an estimate of the direct
cash costs to produce tantalum contained in a technical grade oxide product.

The Blue River Project is located near the village of Blue River, which is
approximately 250 km north of the city of Kamloops and approximately 90 km
south of the town of Valemount. The Project comprises 105,373 hectares (1,000
km^2) of mineral claims. Power transmission lines, rail, and paved and
gravel roads are all adjacent to, or within the property boundaries.
Transalta Corp.'s 18 MW Bone Creek run-of-river hydroelectricity project near
the project was commissioned in June 2011.
