Attention Business Editors:
Canadian Arrow Mines Receives Exceptional Nickel Recoveries from Recent Testwork
SUDBURY, ON, April 16 /CNW/ - Canadian Arrow Mines, Ltd. (CRO: TSX-V)
(the "Company") is pleased to provide an update on the metallurgical test-work
program underway on ores from the Kenbridge Nickel Project in Northwestern
Ontario. Xstrata Process Support (XPS) of Sudbury, Ontario recently completed
a series of variability tests as part of the Phase 1 program to verify and
optimize the flotation circuit for Kenbridge. Results of the open circuit
cleaning and rougher flotation test-work indicate high recoveries of nickel
and copper at saleable concentrate grade can be obtained from the lower grade,
open pit Kenbridge ores.

-----------------------------------------
Ore grade - Ni, Cu % 0.42%, 0.19%
-----------------------------------------
Nickel recovery 83.3%
-----------------------------------------
Copper recovery 91.2%
-----------------------------------------
MgO content 2.3%
-----------------------------------------
Combined Ni/Cu grade 11.0%
-----------------------------------------
The open circuit recovery of 83.3% nickel is a marked improvement on the
72% used for the low grade open pit ore in Arrow's recently published
Preliminary Economic Assessment study, (Feb. 28, 2008). These preliminary
flotation tests have produced saleable bulk nickel/copper concentrate grades
with an exceptional upgrade ratio for nickel of 18:1 which highlights the
potential of the Kenbridge deposit. These test results were performed in an
open circuit and as such are un-optimized. Improved efficiencies and further
gains in metallurgical response are being explored by the XPS team in the form
of rougher concentrate regrind and locked cycle tests.

Kim Tyler, President of Canadian Arrow Mines, comments "We are very
pleased with the results of the XPS flotation work and look forward to the
final results from the locked cycle tests. These nickel and copper recoveries
are well above historical results for low grade ores and will have a positive
impact on the economics of the open pit and bulk underground resources at
Kenbridge. The XPS metallurgical program will continue over the next few
months to further optimize these reported results, test the flotation response
of higher grade underground ores and determine the design parameters for the
grinding circuit - all key requirements for the upcoming bankable feasibility
study."
