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.
