1. Commerce Resources Corp. Updates Metallurgical Programs for the Ashram
Rare Earth Deposit
December 10, 2014 - Commerce Resources Corp. (TSXv: CCE, FSE: D7H) (the “Company”
or “Commerce”) is pleased to provide an update on its metallurgical programs for the Ashram
Rare Earth Deposit. The primary objectives of the current programs are to demonstrate the entire
flowsheet (mini-pilot / bench testing) through to production of several kilograms of marketable
mixed rare earth carbonate concentrate (REC), as well as to produce a sample of high purity
mixed RE chloride concentrate, to further establish flowsheet product versatility.
Commerce Resources President Chris Grove states “These are significant results showing
continued advancements on the fundamentals for our Ashram REE Deposit. We are fortunate to
be able to underwrite programs both in the lab and in the field to advance our world class asset,
and further, appreciate the interest we are receiving from industry.”
Highlights:
 Reproduced baseline flotation flowsheet using varied Ashram feedstock material
 Improved flotation concentrate grades
 Improved flotation concentrate recoveries
 Initial program expanded to produce 500 g of mixed RE chloride concentrate, of high
purity, anticipated to further demonstrate flowsheet product versatility
 Demonstrated successful hydrochloric (HCL) acid regeneration on synthetic solution
with up to 66% recovery into 24-26% HCl concentrated solution.
The current testwork is aimed at optimizing the grinding and flotation circuits in a lead up to the
implementation of a flotation mini pilot plant that remains on schedule for late January 2015
initiation.
Recent work has successfully reproduced and improved flotation grades and recoveries achieved
previously. This further confirms the robustness of the baseline flowsheet developed to date [test
sequence of Flotation + HCl leach + WHIMS], which has produced high-grade mineral
concentrates of >40% TREO at >70% recovery. Select flotation concentrate results are
summarized in the table below.

2. Table 1: Recent Flotation Results Compared to the Baseline
Test Stage Mineral Concentrate
(% TREO)
Recovery
(%)
Mass Pull
(%)
55‐25/279 Flotation 17% 73% 9%
55‐25/298 Flotation 13% 78% 12%
III Ro 002 Flotation 12% 77% 14%
58.34 R+S Flotation 9% 87% 18%
III Ro 004 Flotation 10% 81% 17%
Baseline Flotation 9% 81% 17%
It is anticipated that improvements to the baseline flotation concentrate (9% TREO at 81%
recovery and 17% mass pull) will improve the performance of the subsequent HCl pre-leach
(e.g. resulting in lower acid consumption) and WHIMS stages (cleaner separation). This
potentially will result in a mineral concentrate of even higher-grade and/or recovery than
previously produced (44% at 71% recovery). A simplified version of the baseline flowsheet is
illustrated below.

3. Both mineral processing and hydrometallurgical testing is being undertaken in parallel to
optimally advance the schedule for full demonstration of the flowsheet (mini pilot plant and
bench tests).
In addition to a mixed REC product, the flowsheet circuit will also now produce approximately
500 g of mixed RE chloride of high purity (i.e. meets impurity tolerances of typical industry
processors) for evaluation by third party processors and strategic investors. Mixed RE chloride
concentrate is a common feedstock to world separation facilities and the Ashram flowsheet can
be easily modified to produce this as well as a mixed REC concentrate, further demonstrating the
versatility of its metallurgical flowsheet.
Testing of the hydrometallurgical flowsheet has focused first on HCl acid recovery from the pre-leach
circuit. Preliminary results on synthetic samples indicate at least 66% recovery is attainable
into a solution of ~24-26% concentration. This suggests the majority of the acid consumed in the
pre-leach may be recovered and fed back into the circuit, significantly reducing operating costs.

statements. Forward looking statements in this press release include but are not limited to reference to the
objectives of the current programs; to produce a sample of high purity mixed RE concentrate; implementation of a
flotation mini pilot plant for January 2015; anticipated improvements to the baseline floatation concentrate;
improving the performance of the HCI pre-leach; producing a mineral concentrate of higher grade and recovery than
previously produced; recovery of 66% into a solution of ~24-26% concentration and projections that the majority of
acid consumed in the pre-leach may be recovered and fed back into the circuit to significantly reduce costs.
These forward-looking statements are based on the opinions and estimates of management and its consultants at the
date the information is disseminated. They are subject to a variety of risks and uncertainties and other factors that
