Copper Mountain Mining Corporation
("CMMC" or the "Company") announces assay results from
eight diamond drill-holes completed in the Saddle zone and below Pit 2 of the
Copper Mountain project. Drilling was targeted at defining additional
mineralization in areas outside of the mine plan, specifically, the upper
part of the Saddle zone and below the Pits 1 and 2. Drilling has
defined some additional mineralization within the Saddle zone and, more
importantly, demonstrated that mineralization in the Pit 2 area extends to
significant depths below the currently planned Super Pit. Both grade
and continuity of mineralization below Pit 2 appears to be improving with
depth.
A total of fourteen holes were drilled from the Saddle Zone along six
northwest-southeast oriented sections which were spaced on approximate 60m centres (see attached plan map). Results from five
holes within the Saddle zone and three holes below Pit 2 are the subject of
this release. Drill holes 10SD-63, 65, 67, 69and 70 are shorter holes
within the Saddle zone, whereas 10SD-68, 71 and 75 are the deeper holes
testing below Pit 2. Drill hole 10SD-75 is the lone
hole that was drilled in a south-westerly direction from the north side of
the Pit 2. A summary of the significant drill intercepts is presented in the
table below, and drill hole locations can be found
on the attached plan and section.

Drilling in the western part of the Saddle Zone yielded favourable results, which were reported in a previous
press release on Jan 13th, 2011; however, the current holes
drilled in the Saddle zone only returned relatively narrow intersections, and
drill holes 10SD-67 and 70 did not contain significant intersections. Drill
holes that were extended through the Saddle zone and below Pit 2 were
consistent in yielding significant intersections. The position of these drill
intersections are shown on the attached drill section and plan.
Intersections in drill holes DS-68, 71 and 75 indicate that mineralization
extends to depths of greater than 200m below the planned Super Pit.
The 558m of mineralization in 10SD-75 contains some un-mineralized
dyke and barren zones, which if removed, would leave 394m with an average
grade of 0.33% Cu, 1.0 g/t Ag and 0.14 g/t Au, and includes two higher grade
intersections of 54m at 0.62% Cu and 81m grading 0.40% Cu. The current
drill results, together with results released previously, indicate the
possibility for additional pit expansion in the Pit 2 area, however
additional drilling would be required to develop Measured and Indicated
resources in this area.
Core samples from the last five drill-holes of the 2010 exploration
program are currently at the laboratory with assays pending.
The mineralized system at Copper Mountain is classified as a
bulk-tonnage, alkalic porphyry copper deposit that
is hosted within Nicola Group volcanic rocks. Mineralization is
structurally controlled and focused at multi-directional vein intersections
and within vein stockwork systems. Drill
holes are usually drilled at angles of -45 or -55 degrees to provide the best
indication of the lateral extents of vertically oriented
mineralization.
Quality Assurance
The company employs a system of quality control for drill results
which includes the use of blanks, certified reference material (standards)
and check assaying. Core is logged on site and split with a diamond
saw. Samples are shipped to Pioneer Laboratories for analysis.
The drilling program is being supervised by Peter Holbek,
M.Sc., P.Geo., a qualified person as defined by National Policy
Instrument 43-101.
