IN SUMMARY

First Majestic has experienced a new record for quarterly earnings for the second quarter of 2011 due to a 113% increase in average realized silver prices over the second quarter of 2010 and a 13% increase in ounces of silver sold from the second quarter of 2010. Silver equivalent production remained steady with a 1% increase over the first quarter to a total of 1,843,830ounces in the second quarter of 2011, which is up 11% over the same quarter of 2010.

In addition to the Company's record production and profitability, management has been focused on the current expansion taking place at the La Parrilla operation. This expansion which started in December 2010 is progressing well and the expanded flotation circuit is anticipated to start production in September while the expanded cyanidation circuit is expected to begin production in November.

At the Del Toro Silver Mine, steady progress is being made with the Company's newest construction project. In addition, the drilling and development program which commenced in April has begun to define a large oxide resource not previously anticipated and which will be outlined in detail in an upcoming NI 43-101 compliant economic evaluation. In the interim, the re-engineering of this construction project is underway to incorporate a cyanidation circuit of 1,000 tpd running in parallel to the already permitted 1,000 tpd flotation circuit. Foundations for this new mill are scheduled to commence to be laid in September 2011.

Mr. Keith Neumeyer, President and CEO of First Majestic states, "We are witnessing before our eyes the dramatic re-rating of silver as the world awakens to its importance as a fundamental metal for the continued development of the human race. Management's long standing belief of the importance of silver has focused First Majestic into an aggressive expansion plan, originally launched in 2004, and which continues today. We are maintaining our production target of eight million equivalent ounces of silver for fiscal 2011; however, shareholders should expect higher cash costs due to the weakness in the US dollar, higher cyanide, petroleum and electrical prices, and extra security costs. We remain very focused on reducing, as much as possible, the approaching cost increases inherent in the current mining environment, but we also realize that a greater focus on our aggressive growth strategy will mitigate these cost increases to yield economies of scale which is of greater importance in the longer term."

First Majestic is a producing silver company focused on silver production in México and is aggressively pursuing its business plan of becoming a senior silver producer through the development of its existing mineral property assets and the pursuit through acquisition of additional mineral assets which contribute to the Company achieving its aggressive corporate growth objectives.
