First Majestic Updates 2019 Mineral Reserve and Resource Estimates

VANCOUVER, British Columbia, March 30, 2020 (GLOBE NEWSWIRE) -- 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.

  • 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”.

(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:

SPECIAL NOTE REGARDING FORWARD-LOOKING INFORMATION

This press release contains “forward‐looking information” and "forward-looking statements” under applicable Canadian and U.S. securities laws (collectively, “forward‐looking statements”). These statements relate to future events or the Company's future performance, business prospects or opportunities that are based on forecasts of future results, estimates of amounts not yet determinable and assumptions of management made in light of management's experience and perception of historical trends, current conditions and expected future developments. Forward-looking statements include, but are not limited to, statements with respect to: the Company’s business strategy; future planning processes; commercial mining operations; cash flow; budgets; the timing and amount of estimated future production; recovery rates; mine plans and mine life; the future price of silver and other metals; costs of production; costs and timing of the development of new deposits; capital projects and exploration activities and the possible results thereof. Assumptions may prove to be incorrect and actual results may differ materially from those anticipated. Consequently, guidance cannot be guaranteed. As such, investors are cautioned not to place undue reliance upon guidance and forward-looking statements as there can be no assurance that the plans, assumptions or expectations upon which they are placed will occur. All statements other than statements of historical fact may be forward‐looking statements. Statements concerning proven and probable mineral reserves and mineral resource estimates may also be deemed to constitute forward‐looking statements to the extent that they involve estimates of the mineralization that will be encountered as and if the property is developed, and in the case of measured and indicated mineral resources or proven and probable mineral reserves, such statements reflect the conclusion based on certain assumptions that the mineral deposit can be economically exploited.
