or variations thereof, or stating that certain actions, events or results "may", "could", "would", "might" or "will" be taken,
occur or be achieved, or the negative of any of these terms and similar expressions) are not statements of historical fact and
may be forward-looking information.
Forward-looking information is subject to a variety of risks and uncertainties, which could cause actual events or results to
differ from those reflected in the forward-looking information, including, without limitation, risks inherent in the mining
industry including environmental hazards, industrial accidents, unusual or unexpected geological formations, floods, labour
disruptions, explosions, cave-ins, weather conditions and criminal activity; commodity price fluctuations; higher operating
and/or capital costs; lack of available infrastructure; the possibility that future exploration, development or mining results
will not be consistent with the Company's expectations; risks associated with the estimation of mineral resources and the
geology, grade and continuity of mineral deposits and the inability to replace reserves; fluctuations in the price of commodities
used in the Company's operations; risks related to foreign operations; changes in laws or policies, foreign taxation, delays or
the inability to obtain necessary governmental permits; risks relating to outstanding borrowings; issues regarding title to the
Company's properties; risks related to environmental regulation; litigation risks; risks related to uninsured hazards; the impact
of competition; volatility in the price of the Company's securities; global financial risks; inability to attract or retain
qualified employees; potential conflicts of interest; risks related to a controlling group of shareholders; dependence on third
parties; differences in U.S. and Canadian reporting of mineral reserves and resources; potential dilutive transactions; foreign
currency risks; risks related to business cycles; liquidity risks; reliance on internal control systems; credit risks, including
risks related to the Company's compliance with covenants with respect to its BCP Facility; uncertainty of production and cost

expectations and opinions of management on the date the statements are made, and the Company does not assume any obligation to
update forward-looking information if circumstances or management's beliefs, expectations or opinions should change, other than

information.
Note Regarding Reserve and Resource Estimates
All reserve and resource estimates reported by the Company were calculated in accordance with the Canadian National Instrument
43-101 and the Canadian Institute of Mining and Metallurgy Classification system. These standards differ significantly from the
requirements of the U.S. Securities and Exchange Commission ("SEC"). The differences between these standards are discussed in our
SEC filings. Mineral resources which are not mineral reserves do not have demonstrated economic viability.
