2. Forward-Looking Statements
Some of the statements contained in the following material are "forward-looking statements".
All statements in this release, other than statements of historical facts, that address estimated
mineral resource and reserve quantities, grades and contained metal, and possible future
mining, exploration and development activities, are forward-looking statements. Although the
Company believes the expectations expressed in such forward-looking statements are based
on reasonable assumptions, such statements should not be in any way construed as
guarantees of future performance and actual results or developments may differ materially
from those in the forward-looking statements. Factors that could cause actual results to differ
materially from those in forward-looking statements include market prices for metals, the
conclusions of detailed feasibility and technical analyses, lower than expected grades and
quantities of resources, mining rates and recovery rates and the lack of availability of
necessary capital, which may not be available to the Company on terms acceptable to it or at
all. The Company is subject to the specific risks inherent in the mining business as well as
general economic and business conditions. For more information on the Company, Investors
