COPPER MOUNTAIN AMENDS STOCK OPTION PLAN

VANCOUVER, June 14, 2011 /CNW/ --
VANCOUVER, June 14, 2011 /CNW/ - Copper Mountain Mining Corporation (TSX: CUM) (the 'Company' or 'Copper Mountain') announces that the board of directors has approved two amendments to the
Stock Option Plan (the 'Plan') of the Corporation with the approval of
the Toronto Stock Exchange to address ISS Proxy Advisory Services
concerns with the Company's Plan.  The first provides that any grant of
options under the Plan to any non-executive director in any one year
cannot exceed $100,000 determined by the Black Scholes method.  The
second amendment limits the ability of the Corporation to amend the
Plan or any Option without shareholder approval to the following
specified items: (i) to amend typographical, clerical and gramamatical
errors; (ii) to reflect changes to applicable securities laws; (iii) to
change the termination provisions of Options or the Plan which do not
entail an extension beyond the original expiry date; (iv) to include
the addition of a cashless feature, payable in cash or securities,
which provide for a full deduction of the number of underlying
securities from the Plan reserve; and (v) to ensure that the Options
granted under the Plan will comply with any provision respecting the
income tax and other laws in force in any country or jurisdiction of
which an Option holder to whom an Option has been granted may from time
to time be resident or a citizen.  The Corporation is seeking the
approval of shareholders at its annual and special general meeting of
June 23, 2011, to an increase in the number of common shares reserved
for issuance under the Plan from '5,500,000' to '7,500,000' to ensure
the Company has sufficient room in its option plan to incentivize
employees for performance and future growth.
