Vancouver, British Columbia--(Newsfile Corp. - January 18, 2022) - First Majestic Silver Corp. (TSX: FR) (NYSE: AG) (FSE: FMV) ("First Majestic" or the "Company") is pleased to announce fourth quarter production reached a new quarterly record of 8.6 million silver equivalent ounces, consisting of 3.4 million silver ounces and 67,411 gold ounces, representing a 17% increase compared to the prior quarter. Additionally, full year 2021 production reached a new Company record of 26.9 million silver equivalent ounces, consisting of 12.8 million silver ounces and 192,353 gold ounces, or a 32% increase over 2020.

The Company is also pleased to announce its 2022 guidance of producing between 32.2 to 35.8 million silver equivalent ounces, consisting of 12.2 to 13.5 million ounces of silver and 258,000 to 288,000 ounces of gold, with AISC cost guidance of between $16.79 to $18.06 per silver equivalent ounce.

Q4 2021 HIGHLIGHTS

• Total production reached 8.6 million silver equivalent ounces, representing a 17% increase over the prior quarter. Silver production reached 3.4 million ounces, representing a 2% increase over the prior quarter and the Company's third highest quarterly silver production. Gold production reached 67,411 ounces, representing a 24% increase from the prior quarter and the Company's highest quarterly gold production.
• San Dimas produced a record 4.0 million silver equivalent ounces, consisting of 2.2 million ounces of silver and 23,795 ounces of gold, representing a 17% increase in total production from the prior quarter and the highest quarterly production since acquiring the mine in 2018.
• In November, the Company began test batching surface stockpiles from Ermitaño at the Santa Elena processing plant and in December declared initial production, ahead of schedule, which resulted in a new quarterly production record at Santa Elena. A total of 2.0 million silver equivalent ounces were produced in the quarter consisting of 426,870 ounces of silver and 19,810 ounces of gold. This represents a significant 84% increase in total production from the prior quarter and the highest quarterly production since acquiring the mine in 2015.
• At the end of the fourth quarter, 21 exploration drill rigs were active across the Company's mines consisting of seven rigs at San Dimas, nine rigs at Jerritt Canyon, three rigs at Santa Elena and two rigs at La Encantada.

FY 2021 HIGHLIGHTS

• Silver production in 2021 reached 12.8 million ounces (compared to 11.6 million ounces in 2020) which slightly missed the lower end of the Company's revised guidance range of producing between 13.0 to 13.8 million ounces of silver.
• Gold production in 2021 reached 192,353 ounces (compared to 100,081 in 2020) achieving the higher end of the Company's revised guidance range of producing between 181,000 to 194,000 ounces. This strong performance was primarily due to the processing of Ermitaño ore at the Santa Elena plant and strong silver and gold grades at San Dimas in the fourth quarter.
• Successfully completed the acquisition of the Jerritt Canyon Gold Mine in Nevada, USA adding a fourth operating mine to the Company's portfolio.
• After six years since its initial discovery, the Company successfully began underground ore production from the Ermitaño mine near Santa Elena in the fourth quarter of 2021. This important new mine is expected to significantly increase production and reduce costs at Santa Elena as it ramps up throughout 2022.
• Successfully converted Santa Elena from diesel power to low-cost liquid natural gas ("LNG") with the construction of the new 12.4 MW LNG facility.
• Sold a record 349,278 ounces of silver bullion, or approximately 3% of the Company's silver production, on First Majestic's online bullion store at an average silver price of $31.21 per ounce for total proceeds of $10.9 million.

"First Majestic ended the year with its strongest production quarter in the Company's 20-year history," said Keith Neumeyer, President & CEO. "During the fourth quarter, production at our San Dimas and Santa Elena mines exceeded expectations and reached new records due to a significant improvement in productivity and in silver and gold grades. Consolidated gold production also reached a new record of 192,353 ounces in 2021 due to the acquisition of the Jerritt Canyon mine and the start of production and first pour from the Ermitaño mine at Santa Elena in November."

Mr. Neumeyer continues, "In 2022, total production is expected to increase between 20% to 33% compared to 2021 primarily due to higher production expected at San Dimas, Santa Elena and a full year of production at Jerritt Canyon. In addition, we are planning to invest significantly in exploration and underground development in 2022 in order to prepare a clear path to achieving our goal of producing over 40 million silver equivalent ounces by 2024."

QUARTERLY REVIEW

Total ore processed during the quarter at the Company's mines amounted to 955,810 tonnes, representing a 1% increase compared to the previous quarter. The slight increase in tonnes processed was primarily due to Jerritt Canyon processing higher volumes of lower grade surface material and underground ore partially offset by slightly lower throughput rates at San Dimas, Santa Elena and La Encantada.

Consolidated silver and gold grades in the quarter averaged 125 g/t and 2.42 g/t, respectively, compared to 122 g/t and 2.00 g/t, respectively, in the previous quarter. The increase in consolidated silver and gold grades were primarily due to processing higher grade ore within the Jessica vein at San Dimas and the introduction of Ermitaño's ore into the Santa Elena plant in November.

Consolidated silver and gold recoveries averaged 88% and 91%, respectively, during the quarter. The Company continues to work towards optimizing the metallurgical recoveries of Ermitaño's ore which achieved 61% for silver and 91% for gold during the fourth quarter. The Company plans to modify the Santa Elena processing plant to facilitate finer grinding and improve metallurgical recoveries with the commissioning of a new tailing filter-press, an additional leaching tank and a fourth CCD thickener in the fourth quarter of 2022.

Quarterly Mine by Mine Production Table:

*Certain amounts shown may not add exactly to the total amount due to rounding differences.
*The following prices were used in the calculation of silver equivalent ounces: Silver: $23.33 per ounce; Gold: $1,795 per ounce.

At the San Dimas Silver/Gold Mine:

• San Dimas produced 2,174,353 ounces of silver and 23,795 ounces of gold, representing an increase of 15% in each metal when compared to the prior quarter, for a total of 4,015,346 silver equivalent ounces and representing the highest quarterly production since acquiring the mine in 2018.
• The mill processed a total of 206,738 tonnes of ore with average silver and gold grades of 347 g/t and 3.71 g/t, respectively. Silver and gold grades increased in the fourth quarter as a major high-grade area within the Jessica vein of the Central Block was brought into production at the end of the third quarter.
• Silver and gold recoveries during the quarter averaged 94% and 96%, respectively.
• The Central Block and Sinaloa Graben areas contributed approximately 62% and 35%, respectively, of the total production during the quarter. In addition, the Tayoltita, El Cristo and West Block areas contributed approximately 3% of total production in the quarter.
• A total of seven underground drill rigs were active on the property at the end of the quarter.

At the Jerritt Canyon Gold Mine:

• During the quarter, Jerritt Canyon produced 23,660 ounces of gold, representing a 10% decrease compared to the prior quarter. The decrease was primarily due to harsh winter weather in December which significantly reduced production for a period of two weeks.
• The mill processed a total of 256,374 tonnes of ore with an average gold grade and recovery of 3.41 g/t and 84%, respectively. Increased ore development rates and processing of lower ore grade from surface material continued during the quarter which resulted in higher tonnage with lower average ore grades processed in the plant.
• The SSX and Smith mines contributed approximately 33% and 50%, respectively, of the total production during the quarter. In addition, several surface areas contributed approximately 17% of total production during the quarter.
• During the quarter, the tailings lift at TSF2 and the underground connection drift between the SSX and Smith mines were both completed on-time and under budget.
• A total of nine drill rigs, consisting of four surface rigs and five underground rigs, were active at the end of the quarter.

At the Santa Elena Silver/Gold Mine:

• Santa Elena produced 426,870 ounces of silver and 19,810 ounces of gold representing a 16% decrease in silver and a 164% increase in gold production when compared to the prior quarter for a new quarterly record of 1,955,550 silver equivalent ounces. Production was significantly higher than budget due to the introduction of surface stockpiles from Ermitaño into the processing plant in November compared to previous estimates for the first quarter of 2022.
• The mill processed a total of 224,459 tonnes of ore consisting of 120,717 tonnes of ore from Santa Elena (including the existing heap leach pad) and 103,742 tonnes of ore from Ermitaño.
• Silver and gold grades from Santa Elena averaged 89 g/t and 1.36 g/t, respectively, while silver and gold grades from Ermitaño averaged 54g/t and 4.84 g/t, respectively.
• Consolidated silver and gold recoveries averaged 82% and 92%, respectively, during the quarter. The Company continues to optimize the batch processing and metallurgical recoveries of Ermitaño's ore. The Company is planning to modify the Santa Elena processing plant with the commissioning of a new filter-press, an additional leaching tank and a fourth CCD thickener in the fourth quarter of 2022 in order to facilitate finer grinding, improve metallurgical recoveries and reduce operating costs.
• A total of three drill rigs, consisting of two surface rigs and one underground rig, were active at the end of the quarter.

At the La Encantada Silver Mine:

• During the quarter, La Encantada produced 757,586 ounces of silver, representing a 16% decrease in ounces compared to the prior quarter. The decrease was primarily due to a 13% decrease in silver grade.
• The mill processed a total of 268,239 tonnes of ore with an average silver grade and recovery of 117 g/t and 75%, respectively. The decrease in grade and recoveries were the result of low-grade material being sourced from previously mined areas. During the quarter, the Company began to establish new draw-points within the 660 area in an effort to increase silver grades in the upcoming quarters.
• During the quarter, the Company completed 77 metres of an underground ramp in order to access the Ojuelas orebody which is known to contain higher silver grades. The Company is planning to prepare the area for initial ore extraction in the second half of 2022.
• A total of two underground drill rigs were active on the property at the end of the quarter.

2022 GUIDANCE

The Company expects 2022 total production from its four operating mines to range between 32.2 to 35.8 million silver equivalent ounces consisting of 12.2 to 13.5 million ounces of silver and 258,000 to 288,000 ounces of gold. Based on the midpoint of the guidance range the Company expects silver equivalent ounces to increase 27% when compared to 2021. Silver production is expected to remain consistent with 2021 rates whereas gold production is expected to increase by 42% year-over-year. The increase in gold production is primarily due to the ramp up of production at Ermitaño which is known to contain higher amounts of gold and a full year worth of production from Jerritt Canyon.

A mine-by-mine breakdown of the 2022 production guidance is included in the table below. The Company reports cost guidance to reflect cash costs and all-in sustaining cost per ounce ("AISC") on a per silver equivalent payable ounces. For 2022, the Company is using a 78:1 silver to gold ratio compared to a 72:1 silver to gold ratio in its revised 2021 guidance. Metal price and foreign currency assumptions for calculating equivalents are silver: $22.50/oz, gold: $1,750/oz, MXN:USD 20:1.

GUIDANCE FOR FULL YEAR 2022

* Certain amounts shown may not add exactly to the total amount due to rounding differences.
* Cash Costs and AISC are non-GAAP measures and are not standardized financial measures under the Company's financial reporting framework. The Company calculates cash costs and consolidated AISC in the manner set out in the table below. These measures have been calculated on a basis consistent with historical periods.

The Company is projecting its 2022 AISC to be within a range of $16.79 to $18.06 on a per consolidated payable silver equivalent ounce basis. Excluding non-cash items, the Company anticipates its 2022 AISC to be within a range of $16.34 to $17.56 per payable silver equivalent ounce. An itemized AISC cost table is provided below:

1. AISC is a non-GAAP measure and is calculated based on the Company's consolidated operating performance. 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 equivalent ounce includes estimated royalties and 0.5% Mexico mining environmental fee of $0.15 to $0.17 per payable silver equivalent ounce.

INVESTING FOR FUTURE GROWTH

In 2022, the Company plans to invest a total of $207.8 million on capital expenditures consisting of $86.3 million for sustaining investments and $121.5 million for expansionary projects. This represents a 1% increase compared to the revised 2021 capital budget and is aligned with the Company's future growth strategy of investments in fine grinding technology, processing plant modernizations (including the dual-circuit project installation and expansion of the LNG generation plant at Santa Elena), and to increase underground and plant processing rates at Jerritt Canyon and Santa Elena's Ermitaño mine.

The 2022 annual budget includes total capital investments of $88.0 million to be spent on underground development; $51.9 million towards property, plant and equipment; $45.2 million in exploration; and $22.7 million towards corporate innovation projects. Management may revise the guidance and budget during the year to reflect actual and anticipated changes in metal prices or to the business.

The Company plans to increase underground development in 2022 to approximately 53,700 metres compared to 50,559 metres completed in 2021. The 2022 development program consists of approximately 29,100 metres at San Dimas; 4,950 metres at Jerritt Canyon; 14,900 metres at Santa Elena (including Ermitaño) and 4,750 metres at La Encantada. At San Dimas, the Company is planning to bring the Perez and San Jose Veins, located in the Sinaloa Graben block, into production in the second half of 2022. At Santa Elena, underground development is expected to continue to focus on the Ermitaño mine to continue ramp up procedures to achieve approximately 1,000 tonnes per day of underground ore extraction throughout all of 2022 and further increasing to 2,000 tonnes per day in 2023. At Jerritt Canyon, higher development rates are planned to prepare the SSX/Smith mines for increased ore extraction over the next two years. In addition, the Company is planning to begin underground production in the West Generator mine at the end of 2022. At La Encantada, the Company is continuing to develop towards the Ojuelas orebody to prepare for initial production in the second half of 2022.

The Company is planning to significantly increase exploration drilling in 2022 by 41% to approximately 320,200 metres compared to 227,845 metres which were completed in 2021. The 2022 drilling program is expected to consist of:

• At San Dimas, approximately 98,000 metres of exploration drilling are planned with infill, step-out and exploratory holes focused on near mine and brownfield targets including major ore controlling structures in the West, Central, Sinaloa and Tayoltita blocks.
• At Jerritt Canyon, approximately 135,100 metres are planned and consisting of a mixture of surface and underground infill, step-out and exploratory holes to support the life of mine and test the presence of a new ore body target at Waterpipe II, Wheeler Fault Zone, and Northeast Starvation Canyon. In addition, eight near mine targets located adjacent to historic underground and open pit mines are planned to be drilled from surface. Underground drilling is planned for the Saval 2 mine located north of the main SSX/Smith mine operations and in the West Generator underground mine which is scheduled to be re-opened by the end of 2022.
• At Santa Elena, approximately 68,100 metres are planned with infill and near mine drilling to continue testing the Santa Elena Main, Alejandra del Bajo, America, Fenix and Ermitaño veins. Brownfield drilling is expected to focus on several targets around the mine areas (both Santa Elena and Ermitaño) and greenfield exploration and to continue to test key projects around this very large property.
• Finally, at La Encantada the Company has planned approximately 19,000 metres consisting of near mine drilling to continue adding resources on several existing areas and brownfield drilling to test several high potential targets. The Company recently completed a land access agreement with the Tenochtitlan Ejido which has opened a significant amount of new land that is planned to be explored for the first time in 2022.
