SUDBURY, ON, Sept. 13, 2011 /CNW/ -- SUDBURY, ON, Sept. 13, 2011
/CNW/ - Canadian Arrow Mines, Ltd. (CRO: TSX-V) (the "Company") is
pleased to report on the first set of results received from Xstrata
Process Support (XPS) of Falconbridge Ontario assessing the
metallurgical amenability and quantitative mineralogy of its Kelex
nickel project located near Timmins, Ontario. The test work
performed several flow sheet simulations on a composite sample of
the high grade massive and semi-massive Ni sulphide footwall
portion of the Kelex mineralization collected by the Company.
The test work included both open rougher-scavenger circuit and open
cleaner flotation circuit conditions. The mean head grade of the
sample contained 2.13% Ni and 0.09% Cu. The most optimal
rougher-scavenger simulation concluded: -- 89.9% Ni and 75.5% Cu
rougher-scavenger recovery were achieved at a combined concentrate
grade of 10.2% Ni+Cu grade in the open rougher circuit. The most
optimal open cleaner flotation metallurgical testwork concluded: --
86.1% Ni and 74.9% Cu open cleaner recovery was achieved at a
combined concentrate grade of 10.2% Ni+Cu in the open cleaning
circuit. -- Due to the low Cu head grade, there is no need for
Ni/Cu separation. -- The MgO recovery and grade was 3.2% and 1.9%
respectively. The report further concluded: -- MgO grades in
concentrate were low for all the tests and MgO does not appear to
present a risk to concentrate quality. -- The rougher pentlandite
(Ni-bearing mineral) to pyrrhotite (unwanted Fe-bearing mineral)
ratio for Kelex ore is very good compared to other Ni ores. The
selectivity is comparable and in many cases superior to other Ni
ores. -- The overall open circuit cleaning performance (for the
optimal simulation) for Ni and Cu recovery are comparable to the
response from other ores with similar head grades and
pyrrhotite/pentlandite ratios. Canadian Arrow President, Mr. Kim
Tyler said, "We are very pleased with the results of the XPS
flotation work and look forward to similar results from future work
being contemplated. The results indicate a marketable concentrate
product is quite possible. Positive testwork results are a
key consideration in the Company's efforts to secure favourable
custom milling and concentrate off-take terms." These test results
were performed in an open circuit and as such are
un-optimized. Further work is recommended on grindability and
locked cycle tests to fully evaluate optimal performance under
closed circuit conditions which more approximates performance
expected in a full scale mill. A second sample representing the
lower grade, hanging wall disseminated and stringer style
mineralization is awaiting similar testwork. The Alexo and Kelex
mines have historically produced 87,000 tonnes averaging 3.06%
nickel from both underground and open pit mining. An NI
43-101 Technical Report (April 2011) highlights an indicated
resource of 9.92M lbs of nickel contained in 473,000 tonnes grading
0.96% Ni for the Kelex and Alexo projects. Exploration potential
exists along strike and at depth on both zones. Mineral resources
that are not mineral reserves do not have demonstrated economic
viability. The information in this release was prepared under the
direction of Mr. Kim Tyler, P. Geo., President of the Company, a
Qualified Person as defined by NI 43-101. About Canadian Arrow
Mines: Canadian Arrow Mines Limited is developing two advanced
nickel/copper mining projects located near existing infrastructure
in Ontario, Canada. Its principal asset is the Kenbridge
nickel-copper sulphide deposit located near Kenora, Ontario that
remains open in three directions, is equipped with a 620 m shaft
built and explored by Xstrata Canada Corporation (formerly
Falconbridge Limited) and has never been mined. Highlights of an
updated NI 43-101 Preliminary Economic Assessment Technical Report
(PEA) on Kenbridge reported Sept. 4, 2008 include an operating cash
cost/lb payable net of copper credits of US$3.47/lb nickel. At life
of mine metal prices of US$10/lb Ni and US$2.50/lb Cu; a
CD$1.00:US$0.90 exchange rate and a 7.5% discount rate the PEA
concludes a Net Present Value of CD$253M is achievable. In addition
to the work that Xstrata Canada Corporation (formerly Falconbridge
Limited) expended, Canadian Arrow has additionally expended over
$10M since acquiring the project. The Company also owns the past
producing Alexo and Kelex mines located in the Abitibi nickel
district east of Timmins Ontario containing NI 43-101 indicated
resources of 473,000 tonnes grading an average 0.96 % nickel which
is the focus for earliest resumed production. Mineral resources
that are not mineral reserves do not have demonstrated economic
viability. Additional information relating to Canadian Arrow is
