Other Developments:

Following the successful acquisition of Silvermex Resources Inc. ("Silvermex") which closed on July 3, 2012, the Company immediately established full operating control of the La Guitarra Silver Mine located in the State of Mexico. The Company's current portfolio of four producing silver mines now consists of the La Encantada Silver Mine, the La Parrilla Silver Mine, the San Martin Silver Mine and the La Guitarra Silver Mine.

The total ore processed during the quarter at the Company's four operating silver mines amounted to 666,688 tonnes milled, representing an increase of 8% over the previous quarter. The average head grade in the quarter for the four mines increased by 2% over the previous quarter to 167 g/t of silver. The combined silver recoveries increased from 59% in the second quarter to 62% in the third quarter of 2012.

There are currently 17 diamond drill rigs operating at the Company's four operating mines and at the Del Toro Silver Mine. The Company completed 44,670 metres of diamond drilling in the quarter compared to 35,965 metres of diamond drilling in the second quarter 2012, representing a 24% increase over the prior quarter. The expanded exploration program consists of definition drilling to define Reserves and Resources at the Company's four operating mines, and to assist in mining activities at the Del Toro Silver Mine which is being prepared for production by the end of the year. In addition, the current drilling program will be included in an updated NI 43-101 Technical Report, as the Company's objective is to complete new Technical Reports for each of the Company's mines in 2013.

The Company's underground development in the third quarter consisted of 14,595 metres compared to 13,627 metres of development in the second quarter of 2012.

At the La Encantada Silver Mine:

--  In the third quarter, the processing mill averaged 4,625 tpd of blended
    ore throughput. The three operating ball mills continue to process fresh
    mine ore at a rate of approximately 1,800 tpd with the remaining balance
    of throughput coming from reprocessed tailings. Silver recoveries and
    grades continue to show positive operating improvements as a result of
    the increase in fresh ore from the mine.

--  As previously disclosed, underground development is currently focused on
    areas within the mine that contain lower levels of manganese to assist
    in higher recovery rates. The primary areas of focus have been the San
    Francisco vein and the Milagros Breccia pipe. During the quarter these
    areas came into production and are further anticipated to contribute to
    an overall higher grade and higher recovery for the operation.

--  Due to the extensive underground exploration program underway, a new
    high-grade breccia pipe called "990" was discovered showing silver
    grades in the range of 400 g/t to 500 g/t. This new discovery is
    currently being developed and will be in production late in the fourth
    quarter.

--  Two underground diamond drill rigs are currently active at La Encantada.
    A new NI 43-101 Technical Report is expected to be released before the
    end of the second quarter of 2013.

--  A total of 4,715 metres have been drilled in the third quarter compared
    to 5,451 metres of drilling in the second quarter of 2012. In addition,
    a total of 3,328 metres of underground development was completed in the
    third quarter compared to 3,535 metres of development in the second
    quarter of 2012.

At the La Parrilla Silver Mine:

--  The new dual-circuit processing mill at La Parrilla averaged 2,116 tpd
    of throughput in the third quarter, representing a 4% increase from the
    prior quarter.

--  The new tailing filters were fully operational in the third quarter
    allowing the mill to operate on approximately 80% of recycled water.
    Recycling mill waste water is not only cost efficient and
    environmentally friendly, it also reduces the operational risk in case
    local water supplies are threatened by natural disruptions such as
    severe droughts. La Parrilla is now the second operation under control
    by First Majestic that utilizes this new environmentally friendly
    technology.

--  An aggressive exploration program with diamond drilling, both
    underground and on surface, has indicated the continuation of the
    Rosarios vein system both at depth and along strike which is connecting
    the San Marcos vein with the Rosarios vein system. This area is
    currently being developed at Level 9 to connect the San Marcos mine and
    the Rosarios mine. This connection is expected to be completed during
    the fourth quarter.

--  Three diamond drill rigs are currently operating, two on surface and one
    underground. The total metres drilled during the third quarter amounted
    to 9,201 metres compared to 6,816 metres drilled in the previous
    quarter. Development completed in the quarter totaled 5,122 metres
    compared with 5,247 metres developed in the second quarter.

--  As part of the current expansion program, an intensive underground
    development program and a new ramp system is under construction
    including a new production shaft of which a raise boring machine has now
    completed 480 metres of the pilot shaft. In addition, 350 metres of
    development at Level 11 which will become the new underground rail
    system connecting the different underground areas to the shaft was
    completed during the quarter. This investment is expected to improve
    logistics and the transportation of ore to the mill, ultimately reducing
    overall costs.

--  Following the conclusion of a regional geophysics program in the second
    quarter, a regional exploration drill program is being designed to
    target geological anomalies in far reaching areas within La Parrilla's
    large 69,460 hectare land package. This program is expected to commence
    during the second quarter of 2013. These regional anomalies, never
    explored by modern techniques, are expected to be included in a newly
    updated NI 43-101 Technical Report expected to be released in early
    2013.

At the San Martin Silver Mine:

--  The construction of two new large leaching tanks designed to replace
    some older and smaller leach tanks remains on time and on budget. This
    program is part of First Majestic's regular campaign of improving
    operations by replacing older equipment with newer, cleaner and more
    efficient systems. Further mill improvements are scheduled for 2013 and
    will include, new clarification filters, new tailings filters to
    recirculate water, and to improve environmental conditions.

--  The early results of the exploration drilling program at the
    Rosarios/Huichola veins continue to return very positive results;
    showing further definition of the North/South system of veins that were
    previously unknown. Five drill rigs are currently active within the San
    Martin property. The Company is planning to release an updated NI 43-101
    Technical Report prior to the end of 2012.

--  Total metres drilled in the third quarter amounted to 9,405 metres
    compared to 12,066 metres drilled in the previous quarter. In addition,
    1,809 metres of development were completed in the third quarter of 2012
    compared to 2,172 metres of development in the second quarter of 2012.

At the Del Toro Silver Mine:

--  Construction and development at the Del Toro Silver Mine is well
    underway with initial production expected to reach 1,000 tpd by year
    end, 2,000 tpd by the third quarter of 2013, and 4,000 tpd by mid-2014.

--  During the quarter, the Company received the final Environmental Impact
    Statement permit from the Mexican government (SEMARNAT) approving the
    cyanidation circuit and the enlarged processing facilities at the Del
    Toro Silver Mine. This was the final permit needed to achieve the
    targeted mill capacity of 4,000 tpd by mid-2014.

--  Following the successful platform construction and foundation pouring in
    the first half of the year, mechanical installations continued in the
    quarter at the crushing, flotation and thickeners areas. The
    construction of the 1,000 tpd flotation plant is 75% completed. Initial
    start-up of operations is estimated for the last week of November.

--  Final testing of the sewage water treatment plant was completed during
    the third quarter. Once the mill construction is completed, First
    Majestic is looking forward to being able to recirculate the waste water
    from the town of Chalchihuites back into a collection facility for
    treating and reuse not only saving the environment but also conserving
    water in the region.

--  Six drill rigs are active; three on surface and three underground.
    During the quarter, 36 holes were completed for a total of 11,365
    metres. Drilling continues in order to infill previous holes, and test
    for additional resources and to upgrade previously defined Measured and
    Indicated Resources.

--  Underground development is continuing into the very prospective
    Perseverancia mine and the recently discovered San Nicolas chimney. The
    Company released an updated NI 43-101 Technical Report on August 21,
    2012, which included some of the new resources discovered in this area.
    The results revealed an increase in silver grade of the overall Measured
    and Indicated Resources by 20% to 175 g/t.

--  Development at the San Juan mine for preparation for the upcoming
    production stage continued during the quarter. Ore continues to be
    extracted to surface from the San Juan mine. During the quarter, a total
    of 22,365 tonnes have been mined at Level 9 adding to the mined ore from
    the second quarter bringing the total stockpile of ore on surface to
    56,562 tonnes at quarter end. In addition, the new pump station, new
    powder magazines and the initial work of a new underground shop are
    underway. The total development at Del Toro for the third quarter was
    3,150 metres in the three mines; San Juan, Perseverancia/San Nicolas and
    Dolores.

At the La Guitarra Silver Mine:

--  On July 3, 2012, the Company successfully completed the acquisition of
    Silvermex which resulted in the La Guitarra Silver Mine becoming the
    Company's fourth producing silver mine.

--  Following the acquisition, an aggressive exploration program was
    developed across multiple areas of interest covered by the 39,714
    hectares of mining claims within the Temascaltepec mining District. The
    results of this exploration program are expected to be included in an
    updated NI 43-101 Technical Report scheduled for release by the end of
    2013.

--  The Company plans to increase production levels from the current
    capacity of 350 tpd to 500 tpd at the beginning of 2013. An underground
    development program is being implemented in order to meet the mines for
    a first ramp up. It is expected that throughput during 2013 will be
    maintained at 500 tpd which will result in silver production at La
    Guitarra reaching approximately 1 million silver ounces for the year
    2013.

--  The concentrates being produced at La Guitarra through the old flotation
    circuit are currently being shipped to the La Parrilla mill for leaching
    in the cyanidation process and are being converted into silver dore bars
    which are reducing smelting and refining costs and expected to improve
    the overall economics of the La Guitarra Silver Mine.

--  Permitting for a 1,000 tpd cyanidation processing facility will commence
    in the next few months with a planned commencement of construction in
    the third quarter of 2013. At 1,000 tpd throughput from cyanidation,
    production is anticipated to reach over 2 million ounces of silver dore
    production per year in 2014.

At the Rosario Silver Mine and other assets:

--  First Majestic is reviewing the exploration program for the adjacent
    Rosario and San Juan properties in the Sinaloa Mexico mining area. This
    exploration program is being planned to commence in early 2013. The
    Company is also assessing its portfolio of other exploration properties
    to determine if these additional properties fit within the Company's
    production portfolio.

First Majestic is a silver producing company with operations focused in Mexico. The Company is aggressively pursuing its business plan to become a senior silver producer through the development of its existing assets and the pursuit through acquisition of additional assets that contribute to achieving its corporate growth objectives.
