NEWS RELEASE

New York – AG       March 31, 2022 Toronto – FR Frankfurt – FMV

First Majestic Announces 2021 Mineral Reserve and Resource Estimates 

FIRST MAJESTIC SILVER CORP. (the "Company" or “First Majestic”) is pleased to announce its 2021 Mineral Reserve  and  Resource  estimates  for  its  material  mineral  property  assets  with  an  effective  date  of December 31, 2021. The Company completed a record exploration program totalling 227,845 metres of drilling at its operating mine properties in 2021, representing a 46% 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. During 2021, the Company added more ounces into Reserves than were depleted following a record 26.9 million silver equivalent ounces in annual production.

2021 HIGHLIGHTS (compared to prior Mineral Reserve and Mineral Resource estimates on December 31,  2020)

  • Proven and Probable Mineral Reserves estimates (“P&P”) at the Company’s four producing material assets totalled 177.4 million silver equivalent ounces consisting of 63.0 million ounces of silver and 1.32 million ounces of gold. Silver and gold ounces increased 1% and 118%, respectively, primarily due to the addition of 440,000 ounces of gold at Jerritt Canyon, and the addition of 1.55 million ounces of silver and 280,000 ounces of gold at Santa Elena following its previously reported pre‐ feasibility study in November 2021 which incorporated the Ermitaño Mine into the life of mine. In addition, P&P at La Encantada increased 29% in silver ounces as a result of successful drilling at the Ojuelas and Milagros Breccia deposits.
  • Measured  and  Indicated  Mineral  Resource  estimates  (“M&I”)  for  the  Company’s  four  material assets totalled 332.5 million silver equivalent ounces consisting of 111.0 million ounces of silver and 2.89 million ounces of gold, representing a 1% decrease and a 130% increase, respectively. Jerritt Canyon added 1.60 million ounces of gold in 8 different deposits over its large land package. At  Santa  Elena,  M&I  totalled  18.8  million  ounces  of  silver  and  544,000  ounces  of  gold, corresponding to 70.8 million ounces of silver equivalent representing an 11% increase.
  • Inferred Mineral Resource estimates for the Company’s material assets totalled 235.1 million silver equivalent  ounces  consisting  of  75.3  million  ounces  of  silver  and  2.08  million  ounces  of  gold. Inferred Mineral Resources increased significantly with the incorporation of Jerritt Canyon.

(2)   Totals may not add up due to rounding.

Metal price assumptions used to estimate the December 31, 2021 Mineral Reserves were $22.50/oz for silver and $1,750/oz for gold. This compares to the previous metal price assumptions of $17.50/oz for silver and $1,700/oz for gold used to calculate the Company’s 2020 Mineral Reserves.

MINERAL RESERVE AND MINERAL RESOURCE UPDATE 

As of December 31, 2021, Proven and Probable Mineral Reserves estimates at the Company’s material assets totalled 177.4 million silver equivalent ounces consisting of 63.0 million ounces of silver and 1.32 million ounces of gold. The increase is primarily due to the acquisition of the Jerritt Canyon Gold Mine which added 440,000 ounces of gold grading 5.41 g/t. At Santa Elena, P&P increased 160% to 54.3 million silver equivalent ounces consisting of 11.8 million ounces of silver and 402,000 ounces of gold. The Ermitaño Mine at Santa Elena added Mineral Reserves of 4.7 million ounces of silver and 328,000 ounces of gold grading 52 g/t silver and 3.66 g/t gold. Consolidated tonnage at the material assets increased to 13.2 million tonnes, representing a 57% increase compared to the previous year.

Measured and Indicated Mineral Resource estimates for the material assets totalled 332.5 silver equivalent ounces consisting of 111.0 million ounces of silver and 2.89 million ounces of gold. The Jerritt Canyon acquisition added 1.60 million ounces of gold grading 5.84 g/t gold.  At Santa Elena, M&I Mineral Resource estimates totalled 18.8 million ounces of silver and 544,000 ounces of gold. Consolidated tonnage at the material assets increased to 25.6 million tonnes, representing a 54% increase compared to the previous year. Measured and Indicated Mineral Resources estimates are reported inclusive of Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have a demonstrated economic viability.

Inferred Mineral Resources at the material assets totalled 235.1 million silver equivalent ounces consisting of 75.3 million ounces of silver and 2.08 million ounces of gold.

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, 2021. The Mineral Reserve estimates were prepared under the supervision of Ramón Mendoza Reyes, P.Eng., 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 Payable * Au Price) / (Ag Recovery * Ag Payable * Ag Price).

(b) Metal prices considered for Mineral Reserves estimates were $22.50/oz Ag and $1,750/oz Au for all sites. The    silver‐equivalent factor used for Jerritt Canyon was 77.8 g/t Ag‐Eq per 1 g/t Au.

(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 2021 Annual Information Form.

5.  A two‐step constraining approach has been implemented to estimate reserves for each mining method in use: A General Cut‐Off Grade (GC) was used to delimit new mining areas that will require development of access, infrastructure and all 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 2021 Annual Information Form.

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 aspects, 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 2021 Annual Information Form.
