This notice may contain "forward looking information" within the meaning of
Canadian securities legislation and "forward-looking statements" within the
meaning of the United States Private Securities Litigation Reform Act of 1995
(collectively, "forward-looking statements"). These forward-looking statements
are made as of the date of this notice and Copper Mountain does not intend, and
does not assume any obligation, to update these forward-looking statements,
whether as a result of new information, future events or otherwise, except as
required under applicable securities legislation.

All statements, other than statements of historical facts, are forward-looking
statements. Generally, forward-looking statements relate to future events or

regarding future events.

In certain circumstances, forward-looking statements can be identified, but are
not limited to, statements which use terminology such as "plans", "expects",
"estimates", "intends", "anticipates", "believes", "forecasts", "guidance",
scheduled", "target" or variations of such words, or statements that certain
actions, events or results "may", "could", "would", "might", "occur" or "be
achieved" or the negative of these terms or comparable terminology. In this
notice, certain forward-looking statements are identified, including the
expected nominal value remaining outstanding of the Bonds, anticipated
production at the Copper Mountain Mine, and expectations for other economic,
business and/or competitive factors. Forward-looking statements involve known
and unknown risks, uncertainties and other factors that could cause actual
results, performance, achievements and opportunities to differ materially from
those implied by such forward-looking statements. Factors that could cause
actual results to differ materially from these forward-looking statements
include, among others, the protection of the Company's IT systems or a component
of such systems impacting the Company's reputation and results of operations,
the successful exploration of the Company's property in Canada, market price,
continued availability of capital and financing and general economic, market or
business conditions, the Company's ability to comply with its financial
covenants under its Bond terms and meet its future cash commitments, extreme
weather events, material and labour shortages, the reliability of the historical
data referenced in this document and risks set out in Copper Mountain's public
documents, including the management's discussion and analysis for the quarter
ended September 30, 2022 and the annual information form dated March 29, 2022,
each filed on SEDAR at www.sedar.com. Although Copper Mountain has attempted to
identify important factors that could cause the Company's actual results,
performance, achievements and opportunities to differ materially from those
described in its forward-looking statements, there may be other factors that
cause the Company's results, performance, achievements and opportunities not to
be as anticipated, estimated or intended. While the Company believes that the
information and assumptions used in preparing the forward-looking statements are
reasonable, undue reliance should not be placed on these statements, which only
apply as of the date of this notice, and no assurance can be given that such
events will occur in the disclosed time frames or at all. Accordingly, readers
should not place undue reliance on the Company's forward-looking statements.
