SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS

This news release includes certain "Forward-Looking Statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 and “forward-looking information” under applicable Canadian securities laws. When used in this news release, the words "anticipate", "believe", "estimate", "expect", "target", "plan", "forecast", "may", "schedule" and similar words or

expressions, identify forward-looking statements or information. These forward-looking statements or information relate to, among other things: the anticipated timing of closing of the Arrangement; future growth potential for First Majestic, SilverCrest and their respective businesses; and future silver production.

Forward-looking information relating to future silver production, future growth potential for First Majestic, SilverCrest and their respective businesses is based on management of the applicable parties’ reasonable assumptions, estimates, expectations, analyses and opinions, which are based on such management’s experience and perception of trends, current conditions and expected developments, and other factors that management believes are relevant and reasonable in the circumstances, but which may prove to be incorrect. Assumptions have been made regarding, among other things, the price of silver, gold, and other metals; costs of development and production; estimated production rates for silver and other metals produced by the parties; the estimated costs of development of development projects; First Majestic and/or SilverCrest’s ability to operate in a safe and effective manner and their ability to obtain financing on reasonable terms.

These statements reflect the parties’ respective current views with respect to future events and are necessarily based upon a number of assumptions and estimates that, while considered reasonable by the respective parties, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies. Many factors, both known and unknown, could cause actual results, performance or achievements to be materially different from the results, performance or achievements that are or may be expressed or implied by such forward-looking statements or information and the parties have made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: satisfaction or waiver of all applicable conditions to closing of the Arrangement including, without limitation, receipt of all necessary court, stock exchange, creditor and regulatory approvals or consents and lack of material changes with respect to First Majestic and SilverCrest and their respective businesses, all as more particularly set forth in the Arrangement Agreement; fluctuations in general macro-economic conditions; fluctuations in securities markets and the market price of First Majestic’s shares; fluctuations in the spot and forward price of silver, gold, base metals or certain other commodities (such as natural gas, fuel oil and electricity); fluctuations in the currency markets (such as the Canadian dollar and Mexican peso versus the U.S. dollar); changes in national and local government, legislation, taxation, controls, regulations and political or economic developments in Canada or Mexico; operating or technical difficulties in connection with mining or development activities; risks and hazards associated with the business of mineral exploration, development and mining (including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins and flooding); risks relating to the credit worthiness or financial condition of suppliers, refiners and other parties with whom the parties do business; inability to obtain adequate insurance to cover risks and hazards; and the presence of laws and regulations that may impose restrictions on mining, including those currently enacted in Mexico; employee relations; relationships with and claims by local communities and indigenous populations; availability and increasing costs associated with mining inputs and labour; the speculative nature of mineral exploration and development, including the risks of obtaining necessary licenses, permits and approvals from government authorities; diminishing quantities or grades of mineral reserves as properties are mined; title to properties; and the factors identified under the caption "Risk Factors" in First Majestic’s Annual Information Form, and under the caption "Risk Factors" in SilverCrest’s Annual Information Form.

Readers are cautioned against attributing undue certainty to forward-looking statements or information. Although the parties have attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be anticipated, estimated or intended. The parties do not intend, and do not assume any obligation, to update these forward-looking statements or information to reflect changes in assumptions or changes in circumstances or any other events affecting such statements or information, other than as required by applicable law.
