COPPER MOUNTAIN MINING CORPORATION - DRILLING IN ORIOLE ZONE CONFIRMS HIGHER GRADE MILL FEED
Copper Mountain Mining Corp. has released assay results from 20 diamond
drill holes completed in the Oriole and Rifle areas of the Copper
Mountain project, where a major drill program continues. Two deep holes
have been completed below the Pit 3 area and have been logged, split
and the core has been sent out for assay. Additionally, a number of
deep, angle holes have been recently drilled around and below the
planned superpit targeting geophysical anomalies and possible
extensions to mineralization. Assays for the deep holes are pending.
Oriole area
The drill program in the Oriole area provides results required to
complete a detailed mine plan which allows for additional near-surface
extraction of higher grade material in the early years of production. A
total of 2,200 metres of drilling was completed in 16, shallow drill holes,
which were primarily infill holes on the margins of the proposed pit
area. The drilling provided more definitive geological and grade
information and, together with the shallow percussion drilling,
completed in October, will result in improved reserve modelling. All of
the holes from the current program are inclined at minus-45 degrees and
drilled on east-west sections across the vertically oriented
mineralization. All but one of the holes returned above-cut-off-grade
mineralized intersections.

Rifle area
An additional four holes were drilled on the margin of a geophysical
chargeability anomaly in an area approximately one kilometre south of the Oriole
deposit. This area was originally proposed for waste rock storage. Past
exploration had defined a low level soil geochemical anomaly in the
area and a number of near-surface intersections had been obtained in
past drilling. The four new holes that form two east-west sections were
drilled to determine the orientation and geological characteristics of
the mineralization. Not all assays have been received but results thus
far confirm the presence of mineralization. Additional follow-up work
is being planned prior to using this area for waste rock storage.

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 multidirectional vein intersections and within vein
stockwork systems. Drill holes are usually drilled at angles of minus-45 or
minus-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 geochemical
analysis of copper with all values of greater than 1,000 parts per million copper
being reanalyzed by assay methods for copper, gold and silver. The
drilling program is being supervised by Peter Holbek, MSc, PGeo, a
qualified person as defined by National Policy Instrument 43-101.
We seek Safe Harbor.
