Section 21E of the Securities Exchange Act of 1934 of the United States.
Forward-looking statements are subject to a variety of risks and
uncertainties which could cause actual events or results to differ from
those reflected in the forward-looking statements, including, without
limitation, risks and uncertainties relating to foreign currency
fluctuations; risks inherent in mining including environmental hazards,
industrial accidents, unusual or unexpected geological formations, ground
control problems and flooding; risks associated with the estimation of
mineral resources and reserves and the geology, grade and continuity of

mining results will not be consistent with the Company's expectations;
the potential for and effects of labour disputes or other unanticipated
difficulties with or shortages of labour or interruptions in production;
actual ore mined varying from estimates of grade, tonnage, dilution and
metallurgical and other characteristics; the inherent uncertainty of

expenses, commodity price fluctuations; uncertain political and economic
environments; changes in laws or policies, foreign taxation, delays or
the inability to obtain necessary governmental permits; and other risks
and uncertainties, including those described under Risk Factors Relating

in addition based on various assumptions including, without limitation,
the expectations and beliefs of management, the assumed long term price
of copper, nickel, lead and zinc; that the Company can access financing,
appropriate equipment and sufficient labour and that the political
environment where the Company operates will continue to support the
