At the La Encantada Silver Mine:

• For the quarter, silver production reached 486,514 ounces representing a 20% decrease over the previous quarter. The decrease in silver production was due to a 6% decrease in tonnes milled and an 18% decrease in silver grades compared to the prior quarter.
• Silver recoveries averaged 68% during the quarter, a 3% increase compared with the prior quarter. 
• Mine production was temporarily halted on October 1^st due to the previously reported fatal accident involving four underground miners. Following inspections by the Company and federal authorities, the mine was given clearance to resume operations on October 6^th.

At the end of December, approximately 61% of the major component equipment modules had successfully arrived on site and the remaining module deliveries are expected on site by the end of February. The Company began installation of the dust collectors and rotary dryer in early January and anticipates the main drive, roasting furnace and cooling system to begin installation in early March.   
• Vertical ventilation raises in the San Javier area were completed in the fourth quarter. The Company anticipates initial production from the San Javier breccia to commence in March with ramp up to full production of approximately 600 tpd by the end of June.

• A total of 8,467 metres of exploration drilling was completed in the fourth quarter compared to 9,138 metres of drilling in the previous quarter.

At the Del Toro Silver Mine:

• During the quarter, Del Toro produced a total of 369,992 silver equivalent ounces reflecting a 22% decrease compared to the prior quarter primarily due to a 6% decrease in throughput, 8% decrease in silver grades and a 15% decrease in lead grades.
• Silver grades and recoveries during the quarter averaged 138 g/t and 74%, respectively.
• Lead grades and recoveries averaged 3.4% and 62%, respectively, producing a total of 2.7 million pounds of lead representing a 28% decrease compared to the previous quarter.
• Underground development completed in the quarter totaled 2,741 metres compared to 2,989 metres developed in the previous quarter.
• Total exploration metres drilled in the quarter amounted to 5,215 metres compared to 6,673 metres of drilling in the previous quarter.

At the San Martin Silver Mine:

• During the quarter, San Martin produced 514,678 ounces of silver and 1,354 ounces of gold for a total production of 617,879 silver equivalent ounces, reflecting a 2% increase compared to the prior quarter and the highest quarterly production rate of 2017. The increase in production was attributed to higher tonnage and silver grades.
• Silver grades and recoveries averaged 257 g/t and 86%, respectively, during the quarter. In addition, gold grades and recoveries averaged 0.6 g/t and 91%, respectively.
• Underground development completed in the quarter totaled 3,211 metres compared with 2,781 metres of development in the previous quarter.
• Total exploration metres drilled in the quarter amounted to 6,828 metres compared to 7,763 metres of drilling in the previous quarter.             

At the La Guitarra Silver Mine:

• During the quarter, La Guitarra produced 166,698 ounces of silver and 1,622 ounces of gold for a total production of 290,654 silver equivalent ounces reflecting a 59% increase compared to the prior quarter.  The increase in production was primarily due to a 59% increase in throughput as new areas in the Coloso mine were brought into production as well as the processing of economical backfills from the La Guitarra mine.
• Silver grades and recoveries averaged 173 g/t and 79%, respectively, during the quarter. In addition, gold grades and recoveries averaged 1.7 g/t and 79%, respectively. 
• A total of 1,818 metres of development were completed in the fourth quarter compared to 1,976 metres of development in the previous quarter.
• Total exploration metres drilled in the quarter amounted to 11,030 metres compared to 6,345 metres drilled in the previous quarter. This significant 74% increase was due to two additional rigs arriving on site in September to increase drilling in the Nazareno, Nazareno de Ancas and the Coloso areas.

2018 Production Outlook and Cost Guidance:

The following 2018 outlook and cost guidance excludes the proposed acquisition of Primero Mining Corp. as announced on January 12, 2018. First Majestic is expected to incorporate the San Dimas operation into its annual guidance following the closing of the transaction which is expected by the end of March.

The Company anticipates 2018 silver production will range between 10.6 to 11.8 million ounces. Based on the midpoint of the guidance range the Company expects a 15% increase in silver production compared to 2017, primarily due to higher silver grades from caving and the start-up of the new roasting circuit at La Encantada. In addition, total production in 2018 is estimated to range between 15.7 to 17.5 million silver equivalent ounces, representing a slight increase from 2017, primarily due to higher silver production at La Encantada offset by less gold by-product credits at Santa Elena.

A mine-by-mine breakdown of the 2018 production guidance is included in the table below. Cash cost and all-in sustaining cost per ounce (“AISC”) guidance is shown per payable silver ounce. Metal price and foreign currency assumptions for calculating equivalents are: silver: $16.50/oz, gold: $1,250/oz, lead: $1.10/lb, zinc: $1.40/lb, MXN:USD 19:1.

*Certain amounts shown may not add exactly to the total amount due to rounding differences.
*Consolidated AISC includes Corporate General & Administrative cost estimates and non-cash costs of $2.43 to $2.70 per payable silver ounce.

The Company is projecting its 2018 AISC, as defined by the World Gold Council, to be within a range of $15.21 to $16.56 on a per payable silver ounce consolidated basis. Excluding non-cash items, the Company anticipates its 2018 AISC to be within a range of $14.40 to $15.66 per payable silver ounce. An itemized AISC cost table is provided below:

1. AISC is a non-GAAP measure and is calculated based on guidance provided by the World Gold Council (“WGC”) in June 2013. AISC is used as a comprehensive measure for the Company’s consolidated operating performance. WGC is a not a regulatory industry organization and does not have the authority to develop accounting standards for disclosure requirements.  Other mining companies may calculate AISC differently as a result of differences in underlying accounting principles, the definition of “sustaining costs” and the distinction between sustaining and expansionary capital costs.
2. Total cash cost per payable silver ounce includes estimated royalties and 0.5% Mining Environmental Fee of $0.10 per ounce.

In 2018, the Company plans to invest a total of $125.4 million on capital expenditures consisting of $51.0 million for sustaining investments and $74.4 million for expansionary projects. This represents an 18% increase compared to the revised 2017 capital budget and is aligned with the Company’s future growth strategy of developing additional mine production levels at each of the Company’s operations, completing the roasting circuit and block caving at La Encantada, investments in microbubble and fine-grinding technologies, in addition to the exploration work at Plomosas which is expected to result in an initial resource estimate by the end of 2018.

The Company is planning to complete a total of 72,477 metres of underground development in 2018, representing a 25% increase compared to 57,902 metres completed in 2017. In addition, the Company is planning to complete a total of 183,000 metres of exploration drilling in 2018, representing a 17% increase compared to 156,539 metres completed in 2017 which consisted of 823 drill holes.

The 2018 annual budget includes capital investments totaling $49.0 million to be spent on underground development, $38.1 million towards property, plant and equipment, $27.4 million in exploration and $11.0 million towards corporate automation and efficiency projects. Management may revise the guidance and budget during the year to reflect actual and anticipated changes in metal prices or to the business.
