Forward-Looking Statements

This document 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 document.

Forward-looking statements relate to future events or future performance
and reflect Capstone management's expectations or beliefs regarding future
events and include, but are not limited to, statements with respect to the
timing and implementation of the proposed transaction and the integration of
Capstone and Far West following the transaction. Assumptions upon which such
forward-looking statements are based include that Capstone and Far West will
be able to satisfy the conditions in the Arrangement Agreement, that the
required approvals will be obtained from the shareholders of each of Capstone
and Far West, that all third party, court, regulatory and governmental
approvals to the transaction will be obtained, tax treatment of the
transaction and that all other conditions to completion of the transaction
will be satisfied or waived. Many of these assumptions are based on factors
and events that are not within the control of Capstone and there is no
assurance they will prove to be correct.

In certain cases, forward-looking statements can be identified by the use
of words such as "plans", "expects" or "does not expect", "is expected",
"budget", "potential", "scheduled", "estimates", "forecasts", "intends",
"anticipates" or "does not anticipate", or "believes", or variations of such
words and phrases or statements that certain actions, events or results
"may", "could", "would", "might" or "will be taken", "occur" or "be achieved"
or the negative of these terms or comparable terminology. By their very
nature forward-looking statements involve known and unknown risks,
uncertainties and other factors which may cause the actual results,
performance or achievements of Capstone to be materially different from any
future results, performance or achievements expressed or implied by the
forward-looking statements. Such factors include, among others, risks related
to actual results of current exploration and development activities; changes
in project parameters as plans continue to be refined; future prices of
metals; possible variations in mineral reserves, grade or recovery rates;
accidents, labour disputes and other risks of the mining industry; delays in
obtaining governmental approvals or financing or in the completion of
development or construction activities; as well as those factors detailed
from time to time in Capstone's interim and annual financial statements and
management's discussion and analysis of those statements, all of which are
filed and available for review on SEDAR at www.sedar.com. Although
Capstone has attempted to identify important factors that could cause actual
actions, events or results to differ materially from those described in
forward-looking statements, there may be other factors that cause actions,
events or results not to be as anticipated, estimated or intended. Capstone
provides no assurance that forward-looking statements will prove to be
accurate, as actual results and future events could differ materially from
those anticipated in such statements.

Accordingly, readers should not place undue reliance on forward-looking
statements.
