Cautionary Statement

This presentation contains certain statements that may be deemed “forward-looking statements”. All statements in this presentation, other than statements of historical fact, that address futureoperations, resource potential, exploration drilling, exploitation activities and events or developments that the Company expects to occur, are forward looking statements. Forward looking statements arestatements that are not historical facts and are generally, but not always, identified by the words “expects”, “plans” “anticipates”, “believes”, “intends”, “estimates”, “projects”, “potential” and similarexpressions, or that events or conditions “will”, “would”, “may”, “could” or “should” occur. Information inferred from the interpretation of drilling results and information concerning mineral resourceestimates may also be deemed to be forward looking statements, as it constitutes a prediction of what might be found to be present when and if a project is actually developed. Although the Companybelieves the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results may differmaterially from those in the forward-looking statements. Factors that could cause the actual results to differ materially from those in forward-looking statements include market prices, exploitation andexploration successes, and continued availability of capital and financing, and general economic, market or business conditions. Investors are cautioned that any such statements are not guarantees offuture performance and actual results or developments may differ materially from those projected in the forward-looking statements. Forward looking statements are based on the beliefs, estimates andopinions of the Company’s management on the date the statements are made. The Company undertakes no obligation to update these forward-looking statements in the event that management’s beliefs,estimates or opinions, or other factors, should change, except as may be required by applicable law.

This presentation may use the term “indicated resource”. The Company advises investors that although this term is recognized and required by Canadian securities regulations (under National Instrument43-101 “Standards of Disclosure for Mineral Projects”), however the US Securities and Exchange Commission does not recognize this term. Investors are cautioned not to assume that any part of or all of themineral deposits in these categories will ever be converted into reserves.

Stephen Nano, President and CEO for the Company and a “Qualified Person” under National Instrument 43-101, has reviewed and approved the scientific and technical information in this presentation.

Cerro Chato silica cap, formed from Silica –clay altered laminated (waterlain?) volcanic ash. Not mineralized

• The Cerro Chato silica cap is composed of barren strongly silicified, laminated volcanic ash.

• December 2016 prospecting outlined a 300 m by 55 m zone of east-northeast oriented colloformbanded epithermal veinlets. The veinlets are up to 20 cm wide, form three veinlet trends and have returned assays up to 10.76 g/t Au and 24 g/t Ag.

• The veinlet trends overlie a large sigmodal shaped resistivity anomaly and may represent “geochemical leakage” from a concealed mineralized zone underlying the silica cap.
