Copper Mountain issues retraction on certain disclosure issues



    VANCOUVER, June 20 /CNW/ - Copper Mountain Mining Corporation ("CMMC" or
the "Company") has been requested by the British Columbia Securities
Commission to issue this retraction and clarification of information
previously released in the Company's press releases, investor relations
materials, and website.
    On earlier versions of the Company's corporate presentation that were
posted on the Company's web site, the Company had reported geological targets
as well as conceptual objectives that included target production rates,
recovery rates and metal production plus an outlook of target timelines that
are not supported by a NI 43-101 technical report. Similarly the Company's
news release of April 26, 2007, and May 7, 2007 the Company disclosed a
targeted quantity for the exploration target to support a production rate for
Copper Mountain Project. These targets are not supported by a 43-101 technical
report and without the appropriate cautionary language required by NI 43-101
(section 2.3(2)). The Company is formally retracting this information and
cautions readers not to rely upon this information.
    The Company's news releases of January 18, 2007, March 28, 2007, April
26, 2007, and May 7, 2007 the Company disclosed historical resources of the
Copper Mountain Project with incorrect cautionary language required by
NI 43-101 (section 2.4) and these resources are not supported by a 43-101
technical report. The Company also had reported in earlier versions of its'
corporate presentation, that were posted on its' web site, current historical
reserve estimates for copper, gold and silver that are not supported by a
NI 43-101 technical report. Additionally the Company's news release of April
26, 2007, and May 7, 2007 the Company disclosed a targeted quantity for the
exploration target to support a production rate for the Copper Mountain
Project. These targets are not supported by a 43-101 technical report and were
disclosed without the appropriate cautionary language required by NI 43-101
(section 2.3(2)). The Company is formally retracting this information and
cautions readers not to rely upon this information.
    The Company's fact sheet that was posted on the Company's web site
disclosed historical resources of the Copper Mountain Project without the
appropriate cautionary language required by NI 43-101 (section 2.4) and are
not supported by a 43-101 technical report. The Company is formally retracting
this information and cautions readers not to rely upon this information. The
fact sheet has now been amended to include the appropriate cautionary language
required by NI 43-101 (section 2.4). On earlier versions of the Company's web
page the Company had posted a published article that disclosed historical
resources of the Copper Mountain Project without the appropriate cautionary
language required by NI 43-101 (section 2.4) and disclosed exploration targets
that are not supported by a current 43-101 technical report. The Company is
formally retracting this information and the article has been removed from the
Company's web site.
    The Company's news release of April 26, 2007 the Company disclosed an
additional 30,000 meters of diamond drilling. The Company would like to
clarify that the Phase I drill program of 15,000 meters recommended in the
company's current technical report was initiated on May 21 and is expected to
be completed during the third quarter of 2007. The additional 30,000 meters of
diamond drilling announced on April 26, 2007 was arranged to ensure that the
Company has drills available for the fall and winter due to the overall
shortage of drills and drillers. In the event that the results of the Phase I
drilling do not support additional drilling, under the terms the Company may
terminate the drill contracts by paying a penalty.
    As part of the Initial Public Offering process the Company has engaged
Orquest to complete a 43-101Technical Report dated June 15, 2007 and is filed
on SEDAR on June 20, 2007. That report, authored by George Cavey, P.Geo, Dave
Gunning, P.Eng, and Peter Holbek, M.Sc. P.Geo., is now complete and it
recommends that the Company complete a two-phased exploration program. It is
recommended that the Phase I program should consist primarily of core drilling
to re-establish the dimensions, grade and geological controls of the Copper
Mountain deposits and to expand areas of existing mineralization. A total of
15,000m of diamond drilling has been recommended in addition to drilling
already completed. Additional work in Phase I should include the creation of a
surface electronic database including mine infrastructure and geological data.
A deep penetrating IP survey has been recommended to assist in locating
lateral displacement of mineralization that is blind to surface. Upon
verification of the historical data and once sufficient drill density has been
achieved in the saddle zone the company has been recommended to complete a
NI43-101 compliant resource estimate for the copper mountain area. If the
resource estimates appear sufficient then a Preliminary Assessment ("PA") is
recommended to be carried out. Successful completion of Phase I drilling, and
positive results from the resource estimate and Preliminary Assessment will
determine whether a Phase II exploration program will be justified. The
estimated costs for Phase I are $4.3 million.
    Phase II work, contingent upon success in Phase I, has been recommended
to consist of additional drilling to bring the spacing sufficient to define
indicated resources in the entire super-pit area; a rough estimate is that
this will require 30,000m of diamond drilling depending upon the extents of
mineralization determined in Phase I. An additional 10,000m of drilling is
budgeted to provide the ability to evaluate some of the peripheral zones such
as Oriole and Voigt in sufficient detail to do preliminary resource estimates.
During this phase, the resource estimates should be updated based on the new
drill data. Favourable results from the Preliminary Assessment together with
increased drill density and conversion of inferred resources to the measured
and indicated classifications would allow a decision to conduct a
pre-feasibility or feasibility study. The feasibility study is budgeted with a
high value assuming that a significant portion of the project engineering as
well as permitting would be included in this phase. The recommended Phase II
program is estimated to cost $13.3 million.
    This press release has been approved by the Company's Qualified Person,
Peter M. Holbek, M Sc. P.Geo. as defined in NI 43-101 for reporting purposes.

    CMMC is currently a private BC resource company. The Company owns 100% of
Similco Mines Ltd which holds the mineral claims and crown grants over the
