Coeur's public disclosures are governed by the U.S. Securities Exchange Act of 1934, as amended, including Regulation S-K 1300 thereunder, whereas SilverCrest discloses estimates of "measured," "indicated," and "inferred" mineral resources as such terms are used in Canada's National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). Although S-K 1300 and NI 43-101 have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, they at times embody different approaches or definitions. Consequently, investors are cautioned that public disclosures by SilverCrest prepared in accordance with NI 43-101 may not be comparable to similar information made public by companies, including Coeur, subject to S-K 1300 and the other reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder. The scientific and technical information concerning Coeur's mineral projects in this communication have been reviewed and approved by a "qualified person" under Item 1300 of SEC Regulation S-K, namely Coeur's Senior Director, Technical Services, Christopher Pascoe. The SilverCrest "qualified person" under NI 43-101 for this communication is N. Eric Fier, CPG, P.Eng, CEO for SilverCrest, who has reviewed and approved its contents.
