Keith Neumeyer, President & CEO of First Majestic, stated, "The first quarter was another successful period for the Company as it continues its growth objective. Our strong financial position ensures the timely construction of our Del Toro mine with the goal of initial production scheduled in the fourth quarter of this year. Also, an updated NI 43-101 and Preliminary Economic Assessment (PEA) on Del Toro is scheduled to be released in the coming weeks."

"While cost inflation continues to be a strong headwind for the mining industry, First Majestic's operational team has done an exceptional job maintaining costs. On a year-over-year basis, total production costs have been reduced by 3% to an industry-leading $29.24 per tonne while many of our peers have experienced cost increases ranging between 25% to 50% per tonne. First Majestic remains on track to meet its production guidance for 2012 and management plans to provide further guidance regarding the Silvermex acquisition once the deal closes over the coming months."

FINANCIAL HIGHLIGHTS

--  The Company generated revenues of $57.8 million for the quarter ended
    March 31, 2012, an increase of $2.5 million or 5% compared to $55.3
    million in the first quarter of 2011 based on higher production totals
    compared with the first quarter 2011.
--  Recognized mine operating earnings of $35.7 million, which was
    consistent with $35.6 million in the first quarter of 2011.
--  Net earnings after taxes for the three months ended March 31, 2012 were
    $26.4 million compared to $23.9 million in the first quarter of 2011, an
    increase of 10%.
--  Earnings per share ("EPS") for the three months ended March 31, 2012 was
    $0.25, an increase of 5% compared to $0.24 for the three months ended
    March 31, 2011.
--  During the quarter, the Company converted the unrealized loss of $4.2
    million related to the prior quarter's one million silver ounce long
    position into gains of $5.475 million. At the end of the first quarter,
    the Company was long 500,000 ounces at an average price of $34.063 per
    ounce which was marked to market at $32.484 at March 31, 2012 resulting
    in an unrealized loss of $0.8 million.
--  Net earnings for the quarter ended March 31, 2012 reflects the
    unrealized loss on silver futures of $0.8 million. Adjusted EPS (a non-
    GAAP measure) after removing the unrealized loss on silver futures was
    $0.26 for the quarter.
--  In January 2012, the Company purchased 757,500 trust units of Sprott
    Physical Silver Trust (PSLV) at $13.20 per unit for a total cost of
    $9,999,000. During Q1 2012, the Company also sold 160,980 trust units at
    an average price of $15.45 per unit for total proceeds of $2.5 million
    and realized a $362,677 gain on the sale. At March 31, 2012, there was
    an unrealized gain of $255,601 recognized related to the remaining
    596,520 trust units, revalued at $13.63 per unit.
--  Cash flows from operations before movements in non-cash working capital
    and income taxes in the first quarter of 2012 increased by 6% to $37.1
    million ($0.35 per share) compared to $35.0 million ($0.35 per share) in
    first quarter of 2011.
--  Cash cost per ounce (a non-GAAP measure) for the first quarter of 2012
    was $8.96, an increase of 8% compared to $8.26 in the first quarter of
    2011. Cash cost was higher primarily due to lower grades and recoveries
    at the La Encantada mine in the first quarter. Since installing a new
    ball mill in mid-April, recoveries have been improving due to a higher
    proportion of fresh ore being processed.
--  Production costs per tonne decreased 3% to $29.24 per tonne compared to
    $30.04 per tonne in the first quarter of 2011, reflecting production
    cost decreases at the La Parrilla mine associated with its increased
    scale of production.
--  The new 1,000 tpd cyanidation circuit at the La Parrilla Silver Mine was
    commissioned effective March 1, 2012. The new parallel 1,000 tpd
    flotation and 1,000 tpd cyanidation circuits (2,000 tpd combined), which
    replaced the old 850 tpd mill, are now fully operational and were
    operating at an average throughput of 1,850 tpd in the month of March
    2012.

IN SUMMARY

First Majestic has experienced another solid quarter of earnings and cash flow due in part to an increase in total production to 2,007,219 silver equivalent ounces, an increase of 10% compared to 1,825,366 silver equivalent ounces produced in the first quarter of 2011. Silver production remained robust during the first quarter with 1,826,803 ounces of silver being produced, representing an increase of 3% compared to 1,769,208 ounces of silver produced in the first quarter of 2011.

At the La Parrilla Silver Mine, the recently expanded 1,000 tpd oxide circuit was commissioned on March 1, 2012 allowing for increases in production of silver dore bars. The second quarter of 2012 will mark the first full quarter of commercial operation for both expanded production circuits (1,000 tpd flotation + 1,000 tpd cyanidation). As a result, cash costs per ounce at La Parrilla are expected to decrease due to the increased scale of production to 2,000 tpd, and a higher portion of silver dore which has a lower refining cost compared to concentrates.

At the La Encantada Silver Mine, the recent installation of the third ball mill is showing a positive effect on silver recoveries. The third ball mill became operational on April 19, 2012 with the objective of increasing recoveries and average head grades by enabling increases in the rate of production of fresh mine ore. Due to ore stockpiling over the past few months and successful developments in the mine, management has decided to bring the fresh ore production component to 1,800 tpd compared with the previous guidance of 1,500 tpd. In addition, the metallurgical testing continues with final assessment of economics. The mill construction progress at the Company's exciting Del Toro Silver Mine remains on track for initial production in the fourth quarter of 2012.

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.
