Leading Independent Advisory Firms ISS and Glass Lewis Recommend that SilverCrest and First Majestic Shareholders Vote FOR the Plan of Arrangement

VANCOUVER, BC, CANADA – First Majestic Silver Corp. (“First Majestic”) and SilverCrest Mines Inc. (“SilverCrest”) are pleased to announce that Glass, Lewis & Co. (“Glass Lewis”) and Institutional Shareholder Services Inc. (“ISS”), two leading independent proxy advisory firms which provide voting recommendations to institutional investors, have each recommended that shareholders of First Majestic and SilverCrest vote FOR the respective shareholders’ resolutions proposed in connection with the plan of arrangement (the "Arrangement") pursuant to which First Majestic will acquire all of the common shares of SilverCrest.

In First Majestic’s report, Glass Lewis summarized their FOR recommendation for the Arrangement as follows*: “In sum, we believe the proposed acquisition of SilverCrest is consistent with First Majestic's growth strategy. In SilverCrest, the Company appears to have identified an attractive acquisition target which will add another producing mine to First Majestic's asset portfolio, increasing production, reserves and the Company's cash and working capital position. Moreover, First Majestic expects to realize synergies and cost savings following completion of the arrangement. Therefore, the combination is expected to be accretive to First Majestic's NAV, reserves, resources and production on a per-share basis. As a result, the acquisition is likely, in our view, to lead to enhanced financial performance and ultimately superior shareholder value. Overall, we believe that the consideration represents a reasonable and fair price for First Majestic to pay given the expected strategic and financial benefits and the opportunity to enhance shareholder value. Thus, we believe the transaction represents an appropriate use of the Company’s equity capital. Based on these factors, along with the support of the board, we believe the proposed share issuance for the arrangement is in the best interests of shareholders.”

In SilverCrest’s report, Glass Lewis summarized their FOR recommendation for the Arrangement as follows*: “Overall, in light of SilverCrest's efforts to explore strategic and transaction alternatives over the past several years, we believe adequate assurance exists for shareholders that the proposed transaction likely represents the best opportunity available at this time to maximize shareholder value. Given the opportunity to participate as investors in a larger, more diverse and higher profile silver producer, while retaining a significant interest in both SilverCrest's producing asset and its exploration properties, we believe the proposed arrangement is strategically and financially compelling. Finally, while the transaction comes at a time when silver prices are at a 5-year low, we believe the exchange ratio is a fair and acceptable level at which shareholders can convert the majority of their investments in SilverCrest to holdings in the enlarged First Majestic, while maintain a direct ownership interest in SilverCrest's exploration properties through shares in New SilverCrest. Based on these factors, along with the support of the board, we believe the proposed arrangement is in the best interests of shareholders.”
