First Majestic Produces 3.9M Silver Eqv. Oz in First Quarter

VANCOUVER, British Columbia, April 19, 2018 (GLOBE NEWSWIRE) -- First Majestic Silver Corp. ("First Majestic" or the "Company") (AG) (FR.TO) (FMV.F) announces total production in the first quarter of 2018 from its six operating silver mines reached 3.9 million equivalent ounces of silver. Total production consisted of 2.2 million ounces of silver, 15,887 ounces of gold, 4.4 million pounds of lead and 1.6 million pounds of zinc.

“Over the last two years, our renewed capital investment program has generated positive changes to the business,” said Keith Neumeyer, President & CEO. “We are projecting a 15% increase is silver production in 2018, however, most of this increase will be realized in the second half of the year as the new roaster at La Encantada ramps up to commercial production. Furthermore, with the recent increase in reserve grades, head grades at the mills are expected to improve resulting in higher production and lower costs as the year develops.”

Quarterly Operational Review:

Total ore processed during the quarter at the Company's six operating silver mines: Santa Elena, La Encantada, La Parrilla, Del Toro, San Martin and La Guitarra, amounted to 809,775 tonnes, representing a 10% increase compared to the previous quarter. The most significant improvement occurred at the Del Toro operation which recorded a 41% increase in mill throughput as higher production rates were achieved from the Dolores mine following ventilation upgrades.

Consolidated silver grades in the quarter averaged 111 g/t compared to 125 g/t in the previous quarter. The 11% decrease in silver grades was primarily the result of a 24% decrease in silver grades at La Encantada. Head grades at La Encantada are expected to increase in the second half of 2018 due to higher production rates from the San Javier area which is known to contain silver grades of between 150 to 200 g/t.

Consolidated silver recoveries averaged 75%, representing a 5% decrease compared to the previous quarter. During the quarter, the manufacturing of the full-scale microbubble flotation cells began and is expected to take approximately seven months to complete. Delivery and installation of the cells at La Parrilla are planned for the fourth quarter of 2018 followed by commissioning and ramp up to commercial production by year end. By using microbubble technology, the Company expects to achieve higher metallurgical recoveries in the treatment of sulphide ore within the flotation circuit at La Parrilla.

The Company's underground development in the first quarter consisted of 14,914 metres, reflecting a 4% increase compared to 14,279 metres completed in the previous quarter. Development remains focused on opening new production areas, exploring high potential zones and new stope preparation.

During the quarter, up to 20 diamond drill rigs were active across the Company’s properties. A total of 44,827 metres in 149 drill holes were completed on the seven properties, representing a 10% decrease in drilled metres compared to the previous quarter.

The roasting project advanced in the first quarter with the mounting of the roasting furnace, rotary dryer, cyclones, grate cooler and fans. At the end of March, approximately 79% of the project was completed. Over the next few weeks, the Company is expected to complete the assembly of the heated gas pipeline, coal pulverizer and electrical system. Commissioning and start up remains on schedule for the end of the second quarter and ramping up to commercial production by the end of the third quarter.
A total of 1,445 metres of underground development were completed in the first quarter compared to 742 metres of development in the previous quarter.
