Nickel Mineralization Discovered at Phillips Project



    VANCOUVER, Aug. 26 /CNW/ - Diamond drilling on Callinan Mines Limited's
(CAA.V) Phillips Lake property near Thompson, Manitoba has discovered nickel
bearing sulphide zones.
    Assays on core from the 2007 winter drill program have returned
significant nickel values as shown in the table below. Widths of
mineralization ranging from 2.3m to 29.4m were intercepted in three holes
completed during the program. Samples containing pentlandite mineralization
within the larger widths graded as high as 2.98% Ni. Additional assays are
currently being carried out on the zones containing nickel values to test for
associated platinum group metal values. All zones remain open at depth and on
strike.
    Testing of one anomaly returned a near-solid sulphide intercept which
assayed 1.35% Ni over 2.3 m at 175 m of vertical depth. Previous operators did
not detect this nickel mineralization. Additional anomalies remain to be
tested. The mineralization occurs in a serpentinized peridotite similar to
that which hosts the nickel deposits along the Thompson Nickel belt.
    The Company plans to carry out detailed ground pulse electromagnetic
surveying (inside and outside the transmitter loop) in the coming winter
season to define the targets and prepare for an extended drill program.
Further drilling will be required to determine the true widths of the
intercepts reported below.

    Holes Cap 6 and Cap 7 were drilled from the same collar location. Cap 13
was collared 250 m north of Cap 6 and 7. Callinan Mines maintains a
quality-control program using industry best practices consistent with National
Instrument 43-101. The program is under the supervision of P.J Deveaux, a
qualified person as defined by National Instrument 43-101. All technical
information is obtained and reported within a formal quality assurance and
quality control (QA/QC) program. Sampling was conducted at a Company facility
in Snow Lake, Manitoba, with two 50/50 per cent splits prepared for each
interval. Core was then shipped by freight to Acme Analytical Laboratories in
Vancouver, BC for assay. Sample preparation and aqua regia digestion ICP-ES
analysis were carried out at Acme's Vancouver facility.
