First Majestic Produces a New Record of 8.8 Million AgEq Ounces in the Third Quarter Consisting of 2.7 Million Silver Ounces and 67,072 Gold Ounces

Vancouver, October 18, 2022 - First Majestic Silver Corp. (NYSE: AG) (TSX: FR) (FSE: FMV) ("First Majestic" or the "Company") announces that total production in the third quarter of 2022 from the Company's four producing operations, the San Dimas Silver/Gold Mine, the Jerritt Canyon Gold Mine, the Santa Elena Silver/Gold Mine and the La Encantada Silver Mine, reached a new Company record of 8.8 million silver equivalent ("AgEq") ounces consisting of 2.7 million ounces of silver and 67,072 ounces of gold. In the first nine months of 2022, the Company has produced 8.1 million ounces of silver and 185,355 ounces of gold for total production of 23.7 million AgEq ounces, or approximately 71% of the Company's 2022 guidance midpoint of producing 32.6 to 34.6 million ounces. The Company's financial results for the third quarter of 2022 are scheduled to be released on Wednesday, November 9, 2022.

THIRD QUARTER HIGHLIGHTS

• Total Production Increased by 14% Q/Q: The Company produced a record 8.8 million AgEq ounces representing a 14% increase when compared to the previous quarter primarily due to higher gold production at San Dimas and Santa Elena.

• Another Production Record at Santa Elena - up 22% Q/Q: Strong metal production from the Ermitaño mine enabled Santa Elena to set another all-time new quarterly production record of 2.7 million AgEq ounces in the third quarter, representing a 22% increase compared to the prior quarter.

• Increasing Mine Production at Jerritt Canyon: Underground development activities continued during the quarter at the West Generator and Saval II mines in order to prepare for higher ore deliveries starting in November. These two new sources of ore feed, along with improved ore grades from the Smith Zone 10 area, are anticipated to increase gold grades and increase the amount of fresh ore feed to the plant by approximately 50% in the fourth quarter.

• Ermitaño Operating on 100% Liquefied Natural Gas ("LNG"): The Company successfully completed the transmission powerline connection from Ermitaño to Santa Elena's LNG powerplant in September enabling the mine to operate on 100% LNG power for the first time. In addition, the Company has begun pre-commissioning activities for expanding the LNG powerplant to 24 MW which will provide additional power for the dual-circuit processing plant at Santa Elena. The expanded powerplant is expected to be fully operational in the fourth quarter following the installation of four 2.5 MW LNG generators.

• 23 Drill Rigs Active: The Company completed a total of 80,370 metres of drilling across the Company's mines during the quarter. Throughout the quarter a total of 23 drill rigs were active consisting of seven rigs at San Dimas, nine rigs at Jerritt Canyon, five rigs at Santa Elena and two rigs at La Encantada. In August, the Company released exploration results (link to news release) from Jerritt Canyon's recently discovered Smith Zone 10, a high-grade mineralized area near active underground infrastructure, which is scheduled to begin mining in the fourth quarter.

"In the third quarter, we produced a new quarterly Company record of 8.8 million silver equivalent ounces, representing a 14% increase quarter-over-quarter," said Keith Neumeyer, President and CEO. "This record production was driven mostly by higher grades at our Santa Elena and San Dimas operations. At Santa Elena, the Ermitaño mine produced 83% of the quarterly ounces as strong gold grades and optimized ore deliveries were achieved. At San Dimas, higher production was driven by increased silver and gold grades which were achieved with the start of production at the Perez Vein in July and continued improvements in dilution control. The Company continues to expect production in the fourth quarter to be another step up in growth with the imminent ramp-up at Jerritt Canyon of the West Generator, Saval II and Smith Zone 10 areas."

QUARTERLY REVIEW

Total ore processed during the quarter at the Company's mines amounted to 836,514 tonnes, representing a 7% decrease compared to the previous quarter. The decrease in tonnes processed was primarily due to a 15% decrease in processed tonnes at Jerritt Canyon as the dual roasters were offline for a planned two-week maintenance period in September. The roasters resumed operations in late September and as of quarter end were back at normal operating rates.

Consolidated silver and gold grades in the quarter averaged 117 g/t and 2.74 g/t, respectively, compared to 114 g/t and 2.29 g/t, respectively, in the previous quarter. The 20% increase in consolidated gold grades was primarily due to higher gold grades at San Dimas and Santa Elena's Ermitaño mine. Gold grades at Jerritt Canyon were relatively unchanged compared to the prior quarter.

Consolidated silver and gold recoveries averaged 87% and 91%, respectively, compared to 84% and 89%, respectively, in the previous quarter. The Company continued to advance the Santa Elena dual-circuit project in order to increase the leaching performance and metallurgical recoveries of the Santa Elena and Ermitaño ores at the processing plant. An additional leaching tank and a fourth CCD thickener was commissioned at Santa Elena in the third quarter which is expected to improve metallurgical recoveries going forward.

*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: $19.22 per ounce; Gold: $1,729 per ounce.

At the San Dimas Silver/Gold Mine:

• San Dimas produced 3,776,124 AgEq ounces during the quarter consisting of 1,649,002 ounces of silver and 23,675 ounces of gold, representing increases of 8% and 29%, respectively, when compared to the prior quarter.
• The mill processed a total of 185,126 tonnes of ore with average silver and gold grades of 289 g/t and 4.10 g/t, respectively. Silver and gold grades were higher in the third quarter compared to the prior quarter due to improvements in dilution control from the long hole stoping in the Jessica and Regina veins. In addition, the Company began initial production from the Perez vein in July.
• Silver and gold recoveries during the quarter averaged 96% and 97%, respectively.
• The Central Block and Sinaloa Graben areas contributed approximately 76% and 24%, respectively, of the total production during the quarter.
• During the quarter, a total of seven underground drill rigs completed 14,292 metres of drilling on the property.

At the Jerritt Canyon Gold Mine:

• During the quarter, Jerritt Canyon produced 16,299 ounces of gold, representing a 13% decrease compared to the prior quarter. The decrease was primarily due to a 15% decrease in tonnes milled as the Company completed its annual maintenance overhaul of the dual roasters in September which resulted in an increased ore stockpile of approximately 27,600 tonnes due to the planned 14-day maintenance shutdown. This large surface stockpile is expected to be processed in the fourth quarter.
• The mill processed a total of 181,056 tonnes of ore with an average gold grade and recovery of 3.41 g/t and 82%, respectively. The Company expects gold grades to improve in the fourth quarter of 2022 as higher-grade ore pods from the Smith Zone 10 area are processed at the mill.
• To increase mine production, the Company is planning to complete a secondary escapeway in the West Generator mine in late October allowing for a major increase in ore deliveries and gold production. This new ore feed, along with the expected restart of the Saval II mine in November, are anticipated to increase gold grades and increase the amount of fresh ore feed to the plant by approximately 50%.
• During the quarter, a total of nine underground drill rigs completed 53,714 metres of drilling on the property.

At the Santa Elena Silver/Gold Mine:

• Santa Elena produced a new quarterly record of 2,733,761 AgEq ounces consisting of 308,070 ounces of silver and 26,988 ounces of gold during the quarter, representing a 20% decrease in silver ounces but a 21% increase in gold ounces when compared to the prior quarter. The increase in gold production was primarily due to processing a higher percentage of ore from the Ermitaño mine which is known to contain higher gold grades than the Santa Elena mine.
• The mill processed a total of 214,387 tonnes of ore consisting of 88,576 tonnes from Santa Elena and 125,811 tonnes from Ermitaño.
• Silver and gold grades from Santa Elena averaged 91 g/t and 0.91 g/t, respectively, while silver and gold grades from Ermitaño averaged 41 g/t and 6.61 g/t, respectively.
• Consolidated silver and gold recoveries averaged 72% and 92%, respectively, during the quarter. The Company continues to advance the dual-circuit project at the Santa Elena processing plant which was approximately 96% complete at quarter end. An additional leaching tank and a fourth CCD thickener were successfully commissioned during the quarter and the new 3,000 tpd tailings filter-press is expected to be commissioned in October. The dual-circuit plant is expected to be fully operational by the end of the fourth quarter following the installation of four new 2.5 MW LNG generators and is expected to result in improved recoveries and increased plant capacity.
• During the quarter, the Company completed the transmission powerline to provide low-cost, clean power to the Ermitaño mine. The connection, which joined Ermitaño to Santa Elena's LNG powerplant, was completed in September allowing the Ermitaño mine to run on 100% LNG power for the first time and eliminated the use of the temporary diesel generators.
• The Santa Elena operation has been awarded the prestigious "Silver Helmet Award" in the category of "Underground Mining of More Than 500 Workers" by the Mining Chamber of Mexico for its outstanding performance in occupational safety and health. The distinguished annual award of excellence is only awarded to a select handful of miners in Mexico.
• During the quarter, a total of five drill rigs consisting of three surface rigs and two underground rigs, completed 8,438 metres of drilling on the property.

At the La Encantada Silver Mine:

• During the quarter, La Encantada produced 779,028 ounces of silver, representing a 10% decrease compared to the prior quarter. The decrease was primarily due to a 14% decrease in silver grades.
• The mill processed a total of 255,945 tonnes of ore with an average silver grade and recovery of 121 g/t and 78%, respectively. The slight decrease in grade was the result of lower grade material being sourced from previously mined areas. The Company remains focused on opening up new draw points in the Cuerpo 660 and La Prieta areas in an effort to increase ore flow and production. The Company also continued development activities in the Ojuelas and Beca-Zone orebodies to increase silver grades and ore production in the coming quarters.
• During the quarter, two drill rigs consisting of one surface rig and one underground rig, completed 3,926 metres of drilling on the property.
