The Company reports non-GAAP measures which include Total Cash Costs per Ounce, Total Production Cost per Tonne, Average Revenue per Payable Equivalent Ounces Sold and Cash Flow Per Share Before Movements in Working Capital. These measures are widely used in the mining industry as a benchmark for performance, but do not have a standardized meaning and may differ from methods used by other companies with similar descriptions.

Keith Neumeyer, President and CEO of First Majestic, states, “As usual, First Majestic is working on multiple fronts to improve the business. During this past quarter, we successfully added a third ball mill at the La Encantada mill allowing for mine ore production to reach 1,800 tpd, which as expected, is resulting in improved recoveries. At La Parrilla, the new processing mill reached name plate capacity in the quarter averaging 2,040 tpd and continues to operate as expected. Furthermore, La Parrilla has been deemed as the Company’s blueprint model for all future personnel training programs and activities. At Del Toro, mill construction and underground development to access the third ore body at San Juan remains a key focus ahead of initial production scheduled in the fourth quarter. And lastly, the addition of the La Guitarra Silver Mine to our portfolio brings another area of focus. In addition to immediate production, this very large and exciting land package will keep us busy for many years to come.”

FINANCIAL HIGHLIGHTS

— Increased silver equivalent production by 14% compared to the second quarter of 2011, though average silver prices fell 27%, the Company managed to limit the reduction of revenues by 19% compared to the second quarter of 2011. — Adjusted EPS (a non-GAAP measure) for the three months ended June 30, 2012 was $0.19, after removing $0.8 million in acquisition costs for Silvermex, $1.1 million in legal fees for the First Silver trial and $3.6 million in losses from investment in silver futures and marketable securities. — Cash flows from operations before movements in non-cash working capital and income taxes in the second quarter of 2012 decreased by 34% to $30.6 million ($0.29 per share) compared to $46.4 million ($0.45 per share) in the second quarter of 2011. — Continued to focus on cost control in a lower silver price market. Production costs per tonne decreased 10% to $26.97 per tonne compared to $30.03 per tonne in the second quarter of 2011, reflecting efficiencies from economies of scale as a result of 28% increase in tonnes of ore milled during the second quarter of 2012. — Subsequent to quarter end, on July 3, 2012, the Company completed the acquisition of Silvermex Resources Inc. (“Silvermex”), whereby First Majestic acquired all of the issued and outstanding common shares of Silvermex. Total consideration for the transaction was valued at approximately $137.0 million at the time of completion. Silvermex’s La Guitarra Silver Mine, located in the State of Mexico, has now become First Majestic’s fourth operating mine and is expected to contribute between 320,000 to 340,000 ounces of silver and approximately 70,000 ounces of silver equivalent from gold to the Company’s consolidated production in the second half of 2012. — Cash cost per ounce (a non-GAAP measure) for the second quarter of 2012 was $8.83, an increase of 6% compared to $8.32 in the second quarter of 2011. Cash cost per ounce was slightly higher primarily due to a decrease in consolidated head grades to 166 g/t Ag compared to 208 g/t Ag in the second quarter of 2011. — Generated revenues of $54.8 million for the quarter ended June 30, 2012, a decrease of $13.3 million or 19% compared to $68.0 million in the second quarter of 2011, due to a decrease of 27% in average realized silver prices. — Recognized mine operating earnings of $31.1 million compared to $46.8 million in the second quarter of 2011, a decrease of $15.7 million or 34%, due to lower revenues and higher depreciation, depletion and amortization expense.

IN SUMMARY

First Majestic has experienced another solid financial quarter primarily due to an increase in total production to 2,102,222 silver equivalent ounces, an increase of 14% compared to 1,843,830 silver equivalent ounces produced in the second quarter of 2011. Silver production remained strong during the second quarter with 1,917,248 ounces of silver being produced, representing an increase of 8% compared to 1,780,379 ounces of silver produced in the second quarter of 2011.

Total ore processed in the quarter reached 615,799 tonnes, an increase of 28% compared to the second quarter of 2011. The increase in milled ore is a direct result of the successful plant expansion at La Parrilla which processed a total of 169,786 tonnes in the second quarter compared to 77,363 tonnes in same quarter of 2011. The average silver grade at La Parrilla decreased to 166 g/t in the quarter due to a larger portion of oxide ore being processed from the Quebradillas open pit compared to previous quarters. The Quebradillas open pit is becoming much larger than originally anticipated.

The La Guitarra Silver Mine acquired in July consists of two underground operation centers and a flotation mill with a capacity of 350 tpd, producing approximately 800,000 ounces of silver equivalent per year consisting of approximately 640,000 ounces of silver and 160,000 ounces of silver equivalent from gold. The Company plans to maintain production levels at 350 tpd for the remainder of 2012. A development program is being defined to prepare the mine for a first ramp up stage in which, by the first quarter of 2013, throughput is planned to reach 500 tpd through the flotation circuit. Since the completion of the acquisition, the concentrates being produced at La Guitarra are being shipped to the La Parrilla mill for further leaching in the cyanidation process, where the La Parrilla processing plant is converting this production into dore bars to reduce smelting and refining costs and to improve La Guitarra’s economics.

Construction of the new milling facility at Del Toro is well underway and currently on schedule. After the completion of the platform construction at the mill site, foundations were poured at the crushing, flotation and thickener areas in the second quarter. In addition, mechanical installation also began at the crushing, flotation and thickener areas. The Company has plans to invest an estimated $58.5 million in construction of the phase one flotation circuit, equipment and underground development of which $23.8 million has been spent during the first half of 2012. Furthermore, an update to the NI 43-101 Technical Report will soon be released to take account for improved metallurgical results and additional drilling and development activity at Del Toro in preparation for production.

First Majestic is a producing silver company focused on silver production in Mexico 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.
