Cautionary Statement
This presentation may contain “forward-looking” statements within the meaning of Canadian securities legislation and the United States Private Securities
Litigation Reform Act of 1995. Forward-looking statements relate to future events or the anticipated performance of the Company and reflect
management’s expectations or beliefs regarding such future events and anticipated performance. In certain cases, forward-looking statements can be
identified by the use of words such as “plans”, “expects”, “is expected”, “budget”, “scheduled”, ”estimates”, ”forecasts”, ”intends”, ”anticipates” 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 words or comparable terminology. By their very nature forward-looking statements involve
known and unknown risks, uncertainties and other factors which may cause the actual performance of the Company to be materially different from any
anticipated performance expressed or implied by the forward-looking statements. Such factors include various risks related to the Company’s operations,
including, without limitation, fluctuations in spot and forward markets for gold, silver and other metals, fluctuations in currency markets, changes in
national and local governments in Mexico and the speculative nature of mineral exploration and development, risks associated with obtaining necessary
exploitation and environmental licenses and permits, and the presence of laws that may impose restrictions on mining. A complete list of risk factors are
described in the Company’s preliminary prospectus and will be detailed from time to time in the Company’s interim and annual financial statements and
management’s discussion and analysis of those statements, all of which are, or will be available, for review on SEDAR at www.sedar.com.
This presentation uses the terms “measured resources”, “indicated resources” and “inferred resources”. The Company advises readers that although these
terms are recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI43-101”)),
the United States Securities and Exchange Commission does not recognize them. Readers are cautioned not to assume that any part or all of the mineral
deposits in these categories will ever be converted in to reserves. In addition, “inferred resources” have a great amount of uncertainty as to their existence,
and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category.
Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, or economic studies, except for
a Preliminary Assessment as defined under NI43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically
or legally mineable.
Although the Company has attempted to identify important factors that could cause actual performance to differ materially from that described in forward-
looking statements, there may be other factors that cause its performance not to be as anticipated. The Company neither intends nor assumes any
obligation to update these forward-looking statements or information to reflect changes in assumptions or circumstances other than required by applicable
law. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from
those currently anticipated. Accordingly, readers should not place undue reliance on forward-looking statements.
Unless otherwise indicated, all dollar values herein are in US$.
