VANCOUVER, March 29 /CNW/ - Copper Mountain Mining Corporation ('CMMC' or the 'Company') announces assay results from the last five
diamond drill-holes of the 2010 exploration program completed in the
Saddle zone and below Pits 1 and 2 of the Copper Mountain project. 
Drilling was targeted at defining additional mineralization in areas
outside of the current mine plan, specifically, within the upper
elevations of the Saddle zone and adjacent to the lower elevations of
the Saddle zone, below the Pits 1 and 2.  Overall, the program was
successful in defining additional mineralization in the western end of
the Saddle zone, expanding mineralization in the Pit 2 area to depth,
and adding mineralization on the north side of Pit 1.  The significant
intersections below the south wall of Pit 2, where both grade and
continuity of mineralization appears to be improving with depth, as
well as the intersections in the western part of the Saddle zone are
expected to be accretive to the resource base and could be a
significant factor in determining future pit expansions.

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 collared
in the Saddle zone, with four extending below Pit 1 and one below Pit
2, are listed in the table below and are the final results from the
2010 drill program.  All six of the holes drilled under Pit 2, one on
each of the six sections, returned significant intersections, with the
highest grades coming from the easternmost drill hole, 10SD-64 (127.5m
grading 1.01% Cu, 2.4 g/t Ag and 0.25 g/t Au).  These intersections
demonstrate that mineralization in Pit 2 extends to depth, locally to
more than 200m below the currently designed Super-pit.

Drill holes 10SD-66, and 74 are shorter holes drilled from the Saddle to
the southwest towards Pit 1 and 10SD-72 and 73 are deeper holes testing
below Pit 1.   Drill holes SD-66 and 74 intersected scattered, narrow
zones of mineralization in the area below northwest wall of Pit 1. 
10SD-72 was drilled deep below the south-eastern side of Pit 1 and
apart from some narrow intersections in the upper part of the drill
hole did not intersect significant mineralization and may have drilled
down through what appears to be a highly albitic, late intrusive phase
which forms the un-mineralized part of the Saddle zone.  10SD-73 was
drilled from the Saddle below the north side of Pit 1 and intersected
174m grading 0.39% Cu, 1.20g/t Ag and 0.08g/t Au, pushing the Copper
King mineralized zone further south into the Pit 1 area.

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.
