 FORWARD-LOOKING STATEMENTS Safe Harbour and Other Disclosures  Cautionary Note to United States Investors Regarding Estimates of Resources and Reserves: This presentation uses the terms "Measured," "Indicated" and "Inferred" mineral resources, which are defined in Canadian Institute of Metallurgy guidelines, the guidelines widely followed to comply with Canadian National Instrument 43-101-- Standards of Disclosure for Mineral Projects ("NI 43-101"). We advise U.S. investors that these terms are not recognized by the SEC. The estimation of measured and indicated resources involves greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. Mineral resources are not mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability. U.S. investors are cautioned not to assume that measured or indicated mineral resources will be converted into reserves. Inferred mineral resources have a high degree of uncertainty as to their existence and their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource exists, or is economically or legally viable.  Under Canadian rules, estimates of "inferred mineral resources" may not form the basis of feasibility studies, pre-feasibility studies or other economic studies, except in prescribed cases, such as in a preliminary economic assessment under certain circumstances. Pershing is a reporting issuer in the United States and is required to discuss mineralization estimates in accordance with US reporting standards. The estimates of proven and probable mineral reserves used in this presentation are in reference to the mining terms defined in the Canadian Institute of Mining, Metallurgy and Petroleum Standards, which definitions have been adopted by NI 43-101. The definitions of proven and probable reserves used in NI 43-101 differ from the definitions in the United States Securities and Exchange Commission's Industry Guide 7. In the United States, a mineral reserve is defined as a part of a mineral deposit, which could be economically and legally extracted or produced at the time the reserve determination is made. Accordingly, information contained in this presentation containing descriptions of Pershing’s or Americas Silver’s mineral deposits in accordance with NI 43-101 may not be comparable to similar information made public by other U.S. companies under the United States federal securities laws and the rules and regulations thereunder. Moreover, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" as in-place tonnage and grade without reference to unit measures. US investors are urged to consider closely the disclosure in Pershing’s Form 10-K for the year ended December 31, 2017 and other SEC filings. You can review and obtain copies of these filings from the SEC's website at http://www.sec.gov/edgar.shtml. Mr. Daren Dell, Chief Operating Officer and a Qualified Person under Canadian Securities Administrators guidelines has approved the applicable contents of this presentation.All scientific and technical information related to drill and surface samples, resource estimate, mineral processing, metallurgy and recovery methods, and mining for the Relief Canyon project is based on information prepared by either Paul Tietz, Certified Professional Geologist #11720, Neil Prenn, P.E. #7844, Carl Defilippi, registered member SME#775870RM, or Mark Jorgensen, MMSA#01202QP who are each Qualified Persons under the definitions established by Canadian National Instrument 43-101.

 NOTESMineral Reserve and Mineral Resource Estimates  CIM Definitions and Standards were followed for Mineral Reserve and Mineral Resource Estimates.Mineral Reserves are estimated at a NSR cut-off value of US$40/tonne at Nuestra Señora, US$54/tonne at San Rafael and US$190/tonne at Galena. The NSR cut-off is calculated using recent operating results for recoveries, off-site concentrate costs, and on-site operating costs.Mineral Resources are estimated at a NSR cut-off value of US$34/tonne at San Rafael, US$40/tonne at Zone 120, US$30/tonne at El Cajón and US$190/tonne at Galena. Mineral Resources at Nuestra Señora are estimated at a 90g/tonne silver equivalent cut-off grade. NSR and silver equivalent cut-offs were calculated using recent or expected operating results for recoveries, off-site concentrate costs, and on-site operating costs.Mineral Reserves are estimated using metal prices of US$16.00/oz Ag, $2.50/lb Cu, $0.90/lb Pb and $0.90/lb Zn.Mineral Resources are estimated using metal prices of US$18.00/oz Ag, $3.00/lb Cu, $1.05/lb Pb and $1.05/lb Zn.Mineral Resources are exclusive of Mineral Reserves and as such the Mineral Resources do not have demonstrated economic viability.A minimum mining width of 4.5 feet was used for estimating Galena Reserves, with a minimum additional dilution of 0.5 feet from both the hanging wall and footwall. A mining recovery of 95% was used to reflect the selective nature of the mining methods used at the operation.A mining recovery of 90% was used for estimating Mineral Reserves at Nuestra Señora and San Rafael to reflect the mining methods used at the operations.Numbers may not add or multiply accurately due to rounding.The Mineral Resource estimate for the Cosalá Operations is based on block models prepared by independent mineral resource consultants. The Nuestra Señora Mineral Reserve and Resource estimate was prepared by Company personnel under the supervision of James Stonehouse, Vice President of Exploration, a Qualified Person for the purpose of NI 43-101. The San Rafael, Zone 120 and El Cajón Mineral Resource estimates were prepared by Paul Tietz, C.P.G., who is an independent consultant and a Qualified Person for the purpose of NI 43-101. The San Rafael Mineral Reserve estimate was prepared by company personnel under the supervision of Shawn Wilson, Vice President of Technical Services, a Qualified Person for the purpose of NI 43-101.The Mineral Resource estimate for the Galena Complex was prepared using a combination of block modelling and the accumulation method. The Mineral Resource estimate was prepared by Company personnel under the supervision of Aaron Gross, C.P.G., a Qualified Person for the purpose of NI 43-101. The Mineral Reserve estimate was prepared by Company personnel under the supervision of Shawn Wilson, Vice President of Technical Services, a Qualified Person for the purpose of NI 43-101.All scientific and technical information related to drill and surface samples, resource estimate, mineral processing, metallurgy and recovery methods, and mining for the Relief Canyon project has been reviewed and approved by either Paul Tietz, Certified Professional Geologist #11720, Neil Prenn, P.E. #7844, Carl Defilippi, registered member SME#775870RM, or Mark Jorgensen, MMSA#01202QP who are each Qualified Persons under the definitions established by Canadian National Instrument 43-101. Drill core at Relief Canyon is boxed and sealed at the drill rig and moved to the Relief Canyon logging and sample preparation facilities by trained personnel. The core is logged and split down the center using a typical table-fed circular rock saw. One half of the core is sent for assay while the other half is returned to the core box and stored at Relief Canyon in a secure, fenced-off, area. Pershing Gold quality assurance/quality control (QA/QC) procedures include the regular use of blanks, standards, and duplicate samples.  22
