First Majestic Reports 4% Decrease of Mineral Reserves

FIRST MAJESTIC SILVER CORP. (the “Company” or “First Majestic”) is pleased to announce its updated Mineral Reserve and Resource estimates for the San Dimas, Santa Elena and La Encantada producing mines as well as its existing non-material mineral assets in Mexico with an effective date of December 31, 2019.

2019 HIGHLIGHTS

  • Proven and Probable Mineral Reserves (“P&P”) at the Company’s three producing silver mines totaled 85.1 million ounces of silver and 733,000 ounces of gold, or 146.5 million silver equivalent ounces, representing a 4% decrease compared to previous estimates
    • Consolidated P&P grades increased by 6% to 320 AgEq g/t (186 g/t silver and 1.6 g/t gold)
    • Excluded 16.6 million silver equivalent ounces from Mineral Reserves as a result of placing the San Martin, La Parrilla and Del Toro operations on temporary suspension
       
  • Measured and Indicated Mineral Resources (“M&I”) for the Company’s seven properties increased by 3% to 267.8 million silver equivalent ounces primarily due to the upgrading of 3.3 million ounces of silver and 219,000 ounces of gold, or 21.6 million silver equivalent ounces, from Inferred to Indicated Resources at Santa Elena’s Ermitaño project
    • Indicated grades at Ermitaño increased by 15% to 449 AgEq g/t (70 g/t silver and 4.59 g/t gold)
  • Inferred Mineral Resources at the Company’s seven properties increased by 8% to 228.7 million silver equivalent ounces

“Our exploration efforts in 2019 were successful at replacing mine depletion at San Dimas and improving resources at the Ermitaño project near Santa Elena,” stated Keith Neumeyer, President and CEO. “Reserves at San Dimas remained relatively unchanged at 101.3 million silver equivalent ounces following robust production of 13.8 million silver equivalent ounces in 2019. At the Ermitaño project, we significantly increased the Indicated Resource by 245% to 30.4 million silver equivalent ounces and improved the grade by 15% to 449 AgEq g/t following a successful infill drill program designed to improve the confidence of the deposit. With an updated total resource of 67.9 million silver equivalent ounces, this project is expected to increase production and reduce costs at Santa Elena once production commences in 2021.”

The following table shows the total tonnage mined from each of the Company’s producing properties during 2019, including total ounces of silver, silver equivalent ounces and tonnage mined. A portion of the production from each mine came from material other than Reserves, as set out below under the heading “Material Mined from Areas Not in Reserves”.

2019 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 2019 Annual Information Form.
(2) Totals may not add up due to rounding.

Metal price assumptions used to estimate the 2019 Mineral Reserves were $17.00/oz for silver, $1,350/oz for gold and $0.95/lb for lead. This compares to the previous metal price assumptions of $17.00/oz for silver, $1,250/oz for gold and $1.00/lb for lead used to calculate the Company’s 2018 Mineral Reserves.

RESERVES AND RESOURCES UPDATE

As of December 31, 2019, Proven and Probable Mineral Reserves at the Company’s three operating mines (San Dimas, Santa Elena and La Encantada) totaled 85.1 million ounces of silver and 733,000 ounces of gold, or 146.5 million silver equivalent ounces, representing a 4% decrease in metal content compared to prior estimates. This variation takes into consideration the effect of mine depletion offset by the conversion of Mineral Resources to Mineral Reserves. Additionally, consolidated P&P grades increased by 6% to 320 AgEq g/t (186 g/t silver and 1.6 g/t gold) at the three operating mines.

The Company reclassified the San Martin, La Parrilla and Del Toro mines as non-material properties following management’s decision to place these operations on temporary suspension in 2019. As a result, a total of 16.6 million silver equivalent ounces were excluded from Mineral Reserves comprised of 5.6 million silver equivalent ounces at San Martin, 2.3 million silver equivalent ounces at La Parrilla and 8.7 million silver equivalent ounces at Del Toro. These excluded ounces will remain in M&I Resources subject to sufficient economic improvements at Del Toro and La Parrilla, as well as a reduction in security concerns at San Martin, to justify a restart of operations.

The Company’s consolidated Measured and Indicated Mineral Resources have increased by 3% in terms of silver equivalent metal content as the result of the exploration programs designed to sustain mineral resources in San Dimas and Santa Elena. Indicated Mineral Resources at Santa Elena’s Ermitaño project increased by 245% to 4.7 million ounces of silver and 311,000 ounces of gold, or 30.4 million silver equivalent ounces. Furthermore, Indicated Resource grades at Ermitaño increased by 15% to 449 AgEq g/t (70 g/t silver and 4.59 g/t gold) following another successful exploration program in 2019 which primarily focused on infill drilling of the main ore body.  

Consolidated Inferred Mineral Resources increased by 6% in terms of silver equivalent metal content as a result of the exploration programs designed to identify new mineral resources. In addition, consolidated Inferred grades increased by 2% to 405 AgEq g/t (224 g/t silver, 2.03 g/t gold, 0.31% lead and 0.31% zinc).

The complete 2019 Mineral Reserve and Resource estimates for all metals, tonnage and grades are shown below in the following tables:

Proven and Probable Mineral Reserves with an effective date of December 31, 2019

(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 National Instrument 43-101 (NI43-101).
(2)  The Mineral Reserves statement provided in the table above is based on internal estimates prepared as of December 31, 2019. The information provided was reviewed and prepared under the supervision of Ramon Mendoza Reyes, PEng, and a Qualified Person (“QP”) for the purposes of NI43-101.
(3)  Silver-equivalent grade is 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. Assumptions details are listed in each mine section of the 2019 Annual Information Form.
(4)  Metal prices considered for Mineral Reserves estimates were $17.00/oz Ag, $1,350/oz Au and $0.95/lb Pb.
(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 and infrastructure and all sustaining costs. A second Incremental Cut-Off Grade (IC) was considered to include laterally adjacent mineralized material which recoverable value pays for the following costs: variable cost of mining and processing, indirect costs, treatment costs, administration costs and plant sustaining costs, but excludes: fixed costs of mining and processing, and development sustaining costs.
(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. These cut-off grades and economic parameters are listed in the applicable section describing each mine in the Company’s 2019 Annual Information Form.
(7)  Tonnage is expressed in thousands of tonnes; metal content is expressed in thousands of ounces.
(8)  Totals may not add up due to rounding.
