First Majestic Announces 2022 Mineral Reserve and Mineral Resource Estimates

FIRST MAJESTIC SILVER CORP. (the "Company" or “First Majestic”) is pleased to announce the 2022 Mineral

Reserve and Mineral Resource estimates for its four mate rial mineral properties with an effective date of

December 31, 2022. Three material properties are currently in production: the San Dimas Silver/Gold Mine,

the Santa Elena Silver/Gold Mine, and the La Encantada Silver Mine. The fourth material property, the Jerritt

Canyon Gold Mine, was recently placed in temporary suspension to focus on ex ploration, definition, and

expansion of the mineral resources and optimization of mine planning and plant operations.

During 2022, the Company completed a total of 249,201 me tres of exploration drilling representing a 9%

increase in metres drilled compared to the prior year . Approximately 80% of this drilling was focused on

near mine or brownfield targets while the remainder was focused on greenfield targets looking for new

discoveries. In 2022, the Company’s Mineral Resource estima tes show an increase in contained silver

equivalent ounces more than offsetting mine depl etion following a record 31.3 million silver equivalent

ounces in annual production.

2022 HIGHLIGHTS (compared to prior Mineral Reserve and Mineral Resource estimates on December 31,

2021)

 Proven and Probable (“P&P”) Mineral Reserves estimates at the Company’s three producing

material assets totalled 136.8 million silver equi valent (“Ag-Eq”) ounces consisting of 61.5 million

ounces of silver and 781,000 ounces of gold. Si lver ounces remained relatively unchanged,

decreasing only 2% after the exploration programs successfully offset depletion due to production

during the year. Gold ounces decreased 41%, primar ily due to the Company’s decision to report

only Mineral Resource estimates for the Jerritt Canyon property after temporarily suspending

production and the record production at Santa Elena with the Ermitaño mine surpassing its

budgeted metal output in 2022.

 Measured and Indicated (“M&I”) Mineral Resource estimates for the four material assets totalled

351.5 million Ag-Eq ounces consisting of 101.7 million ounces of silver and 2.82 million ounces of

gold, representing an 8% and 2% decrease in silver and gold, respectively. Jerritt Canyon added

2

67,000 ounces of gold to its M&I Mineral Resource estimates at the SSX and Smith mines, which

were identified by the 2022 drilling program.

 Inferred Mineral Resource estimates for the Comp any’s four material assets totalled 280.8 million

Ag-Eq ounces consisting of 73. 6 million ounces of silver and 2.36 million ounces of gold.

Expansionary drilling completed during 2022 at Jerri tt Canyon significantly increased the Inferred

Mineral Resource estimates with the addition of 307,000 ounces of gold at the SSX, Smith, and

West Generator mines. Drilling during the past ye ar at San Dimas also increased the Inferred

Resource estimates, adding 8.6 million Ag-Eq ounces consisting of 1.3 million ounces of silver and

25,000 ounces of gold.

2022 PRODUCTION TABLE

(1) Silver-equivalent ounces are estimated considering metal price assumptions, metallurgical recovery for the corresponding mineral type/mineral

process and the metal payable of the corresponding contract of each mine. Details as to the method of calculation can be found in the applicable

tables in each mine section of the Company’s 2022 Annual Information Form.

Metal price assumptions used to estimate the Dece mber 31, 2022 Mineral Reserves were $21.50/oz for

silver and $1,750/oz for gold. This compares to the previous metal price assumptions of $22.50/oz for silver

and $1,750/oz for gold used to calculate the Company’s 2021 Mineral Reserves.

MINERAL RESERVE AND MINERAL RESOURCE UPDATE

As of December 31, 2022, P&P Mineral Reserve estimates at the Company’s three producing material assets

totalled 61.5 million ounces of silver and 781,000 ounces of gold, which represents a total of 136.8 million

Ag-Eq ounces. At the San Dimas and La Encantada mi nes, the P&P Mineral Reserve estimates remained

relatively unchanged as a result of the exploration programs offsetting the production depletion. At Santa

Elena, P&P Mineral Reserve estimates decreased 14% to 47.0 million Ag-Eq ounces consisting of 10.1 million

ounces of silver and 320,000 ounces of gold. The decrea se at Santa Elena is the result of depletion after

record production in the Ermitaño mine during 2022. Consolidated tonnage at the three material assets

was 11.3 million tonnes, with estimated grades of 169 g/ t silver and 2.14 g/t gold. The decrease of 14% in

the consolidated tonnage is primarily due to the depletion in Mineral Reserve estimates at Santa Elena and

the exclusion of the Mineral Reserve estimates for Jerritt Canyon following the Company’s decision to

report only Mineral Resources at that property after temporarily suspending production. This decrease was

partially offset by increases in tonnage at the San Dimas and La Encantada mines.

Proven and Probable Mineral Reserve Estimates with an Effective Date of December 31, 2022

(1) Mineral Reserves have been classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards on Mineral

Resources and Mineral Reserves, whose definitions are incorporated by reference into NI 43-101.

(2) The Mineral Reserve statement provided in the table above have an effective date of December 31, 2022. The Mineral Reserve estimates were prepared under the

supervision of Ramón Mendoza Reyes, PEng, and a Qualified Person ("QP") for the purposes of NI 43-101 who has the appropriate relevant qualifications, and experience

in mining and mineral reserves estimation.

(3) The Mineral Reserves were estimated from the Measured and Indicated portions of the Mineral Resource estimate. Inferred Mineral Resources were not considered

to be converted into Mineral Reserves.

(4) Silver-equivalent grade (Ag-Eq) is estimated considering metal price assumptions, metallurgical recovery for the corresponding mineral type/mineral process and the

metal payable of the selling contract.

(a) The Ag-Eq grade formula used was:

Ag-Eq Grade = Ag Grade + Au Grade * (Au Recovery * Au Paya ble * Au Price) / (Ag Recovery * Ag Payable * Ag Price).

(b) Metal prices considered for Mineral Reserves estimates were $21.50/oz Ag and $1,750/oz Au for all sites.

(c) Other key assumptions and parameters include: metallurgical recoveries; metal payable terms; direct mining costs, processing costs, indirect and G&A costs and

sustaining costs. These parameters are different for each mine and mining method assumed and are presented in each mine section of the 2022 AIF.

(5) A two-step constraining approach has been implemented to estimate reserves for each mine and mining method in use: A Genera l Cut-Off Grade (GC) was used to

delimit new mining areas that will require development of access, infrastructure and sustaining costs. A second Incremental Cut-Off Grade (IC) was considered to include

adjacent mineralized material which recoverable value pays for all associated costs, including but not limited to the variable cost of mining and processing, indirect costs,

treatment, administration costs and plant sustaining costs but excludes the access development assumed to be covered by the block above the GC grade.

(6) The cut-off grades, metallurgical recoveries, payable terms and modifying factors used to convert Mineral Reserves from Mineral Resources are different for all mines

and are presented in each mine section in the 2022 AIF.

(7) Modifying factors for conversion of resources to reserves include consideration for planned dilution which is based on spacial and geotechnical aspects of the designed

stopes and economic zones, additional dilution consideration due to unplanned events, materials handling and other operating as pects, and mining recovery factors.

Mineable shapes were used as geometric constraints.

(8) Tonnage is expressed in thousands of tonnes; metal content is expressed in thousands of ounces. Metal prices and costs are expressed in USD.

(9) Numbers have been rounded as required by reporting guidelines. Totals may not sum due to rounding.

(10) The technical reports from which the above-mentioned information is derived are cited under the heading "Technical Reports for Material Properties" in the 2022

AIF.

M&I Mineral Resource estimates for the four material assets totalled 351.5 million Ag-Eq ounces consisting

of 101.7 million ounces of silver and 2.82 million ounces of gold. The consolidated tonnage was 25.3 million

tonnes with estimated grades of 125 g/t silver and 3.47 g/t gold. The M&I tonnes were relatively unchanged

with a 1% decrease over 2021. M&I Mineral Resources at Jerritt Canyon increased by 67,000 ounces of gold

primarily due to a successful near-mine drilling prog ram at the SSX and Smith mines that outlined new

mineral deposits. M&I Mineral Resources estimates are reported inclusive of Mineral Reserves.
