VANCOUVER, March 7 /CNW/ - 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 13(th), 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.
