2. 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 annual information form and will be detailed from time to time in the
Company’s continuous disclosure, 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 (“NI 43-101”), 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.

Notes to Mineral Reserve Statement:
1.
Cutoff grade of 2.4 grams per tonne (”g/t”) gold equivalent (“AuEq”) based on total operating cost of US$104.73/t. Metal prices assumed are gold
US$1,400 per troy ounce and silver US$25 per troy ounce. Silver supply contract obligations have been referenced in determining overall vein reserve
estimate viability.
2.
Processing recovery factors for gold and silver of 97% and 94% assumed.
3.
Exchange rate assumed is 13 pesos/US$1.00.
4.
The Mineral Reserve estimates were prepared by Mr. Herbert A. Smith P.Eng. of AMC Mining Consultants (Canada) Ltd. and a QP for the purposes of
National Instrument 43-101 (“NI 43-101”).
Notes to Mineral Resource Statement:
1.
Mineral Resources are total and include those resources converted to Mineral Reserves.
2.
A 2.0g/t Au Eq cutoff grade is applied and the AuEq is calculated at a gold price of US$1,625 per troy ounce and a silver price of US$25 per troy ounce.
3.
A constant bulk density of 2.7 tonnes/m3 has been used.
4.
The Mineral Resource estimates were prepared by Mr. Rodney Webster MAusIMM, MAIG and Mr. J. Morton Shannon P.Geo., both of AMC Mining
Consultants (Canada) Ltd. and a QP for the purposes of NI 43-101.
Additional exploration potential estimated at 6-10 million tonnes at grade ranges of 3-5 grams per tonne of gold and 200-400 grams per
tonne of silver. It should be noted that these targets are conceptual in nature. There has been insufficient exploration to define an
associated Mineral Resource and it is uncertain if further exploration will result in the target being delineated as a Mineral Resource.

33. Notes to Investors Regarding the Use of Resources
This presentation has been prepared in accordance with the requirements of Canadian provincial securities laws which differ from the requirements of
U.S. securities laws. Unless otherwise indicated, all mineral reserve and resource estimates included in this presentation have been prepared in
accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining,
Metallurgy and Petroleum classification systems. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for
all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ significantly from the
requirements of the United States Securities and Exchange Commission (the “SEC”), and reserve and resource estimates disclosed in this presentation
may not be comparable to similar information disclosed by U.S. companies.
The mineral reserve estimates in this presentation have been calculated in accordance with NI 43-101, as required by Canadian securities regulatory
authorities. For United States reporting purposes, SEC Industry Guide 7 under the United States Securities Exchange Act of 1934, as amended, as
interpreted by Staff of the SEC, applies different standards in order to classify mineralization as a reserve. As a result, the definition of “probable
reserves” used in NI 43-101 differs from the definition in the SEC Industry Guide 7. Under SEC standards, mineralization may not be classified as a
“reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the
reserve determination is made. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify
mineralized material as reserves under the SEC standards. Accordingly, mineral reserve estimates contained in this presentation may not qualify as
“reserves” under SEC standards.
In addition, this presentation uses the terms “indicated resources” and “inferred resources” to comply with the reporting standards in Canada. The
Company advises United States investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them.
United States investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral
reserves. Further, “inferred resources” have a great amount of uncertainty as to their existence and as to whether they can be mined legally or
economically. Therefore, United States investors are also cautioned not to assume that all or any part of the “inferred resources” exist. In accordance
with Canadian securities laws, estimates of “inferred resources” cannot form the basis of feasibility or other economic studies. It cannot be assumed that
all or any part of “indicated resources” or “inferred resources” will ever be upgraded to a higher category or are economically or legally mineable. In
addition, disclosure of “contained ounces” is permitted disclosure under Canadian securities laws; however, the SEC only permits issuers to report
mineralization as in place tonnage and grade without reference to unit measures.
NI 43-101 also permits the inclusion of disclosure regarding the potential quantity and grade, expressed as ranges, of a target for further exploration
provided that the disclosure (i) states with equal prominence that the potential quantity and grade is conceptual in nature, that there has been
insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral
resources, and (ii) states the basis on which the disclosed potential quantity and grade has been determined. Disclosure regarding exploration potential
has been included in this presentation. United States investors are cautioned that disclosure of such exploration potential is conceptual in nature by
definition and there is no assurance that exploration will result in any category of NI 43-101 mineral resources being identified.
