First Majestic Produces 4.0M Silver Eqv. Oz in Third Quarter

VANCOUVER, British Columbia, Oct.17, 2017(GLOBE NEWSWIRE) -- First Majestic Silver Corp. (NYSE:AG) (TSX:FR) ("First Majestic" or the "Company") announces total production in the third quarter of 2017 from its six operating silver mines reached 4.0 million equivalent ounces of silver. Total production consisted of 2.4 million ounces of silver, 15,414 ounces of gold, 5.2 million pounds of lead and 0.9 million pounds of zinc.

"Consolidated production in the third quarter returned to higher levels compared to the prior quarter," said Keith Neumeyer, President & CEO. "At La Encantada, improvements in throughput and silver grades allowed for a 62% increase in silver production. At Santa Elena and San Martin, total production at each operation beat guidance due to continued strong grades and higher recoveries. At La Parrilla, oxide production improved due to higher grade ore being sourced from the San Marcos mine. Lastly, as a safety precaution following two major earthquakes that struck near the La Guitarra mine in September, we temporarily suspended production for a total of eight days to allow for a full inspection of the operation. The inspection revealed no significant risks or damages allowing for the restart of production."

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 730,652 tonnes, representing a 6% increase compared to the previous quarter. The most significant improvement occurred at the La Encantada operation which recorded a 43% increase in mill throughput as production rates returned to normal levels following the 42 day work stoppage in the prior quarter.

Consolidated silver grades in the quarter averaged 131 g/t compared to 130 g/t in the previous quarter. Higher silver grades were mined and processed at La Encantada and San Martin, however, consolidated silver grades were offset by lower grades at Del Toro. Silver grades at Santa Elena, La Parrilla and La Guitarra remained relatively consistent with the prior quarter.

Consolidated silver recoveries averaged 78%, relatively consistent with the previous quarter. During the quarter, the Company began testing microbubble flotation technology at its Central Lab at La Parrilla. Ore samples from La Guitarra were shipped to site and tested in a six-inch diameter microbubble column. Preliminary results show metallurgical recoveries improved by up to 4% in addition to producing higher concentrate grades. Ore samples from La Parrilla, Del Toro and San Martin are expected to start pilot testing in the fourth quarter of 2017. Pending successful results, the Company will begin installing full scale microbubble columns at each of the four mines in 2018.

The Company's underground development in the third quarter consisted of 14,931 metres, reflecting a 1% decrease compared to 15,121 metres completed in the previous quarter. Development focused on opening new production areas, exploring high potential zones and new stope preparation. The most significant increase in underground development occurred at La Encantada in areas of the mine known to have higher grades, most notably the San Javier and 990 areas, and the San Francisco dyke.

During the quarter, a total of 19 diamond drill rigs were active across the Company's properties consisting of 16 rigs at the six producing mines and three rigs at the Plomosas Silver Project. A total of 48,638 metres in 302 drill holes were completed on the seven properties, representing a 67% increase in drilled metres in the previous quarter. The most significant increases in drilled metres was at Santa Elena, La Guitarra, La Parrilla and La Encantada to catch up with annual program targets. Additional details are stated in their respective mine sections below.

*The following prices were used in the calculation of silver equivalent ounces: Silver: $16.84 per ounce; Gold: $1,279 per ounce; Lead: $1.06 per pound; Zinc: $1.34 per pound.

At the Santa Elena Silver/Gold Mine:

• During the quarter, Santa Elena produced 560,054 ounces of silver and 12,422 ounces of gold for a total production of 1,503,376 silver equivalent ounces reflecting a 7% increase compared to the prior quarter.
• The mill processed a total of 232,662 tonnes, consisting of 141,435 tonnes of underground ore and 91,227 tonnes from the above ground heap leach pad.
• Silver and gold grades of underground ore averaged 112 g/t and 2.4 g/t, respectively. Whereas silver and gold grades from the above ground heap leach pad averaged 39 g/t and 0.7 g/t, respectively.
• A total of 2,724 metres of underground development was completed in the third quarter compared to 2,613 metres of development in the previous quarter.
• A total of 7,406 metres of exploration drilling was completed in the third quarter, consisting of 6,673 metres of diamond drilling and 733 metres of rotary drilling. This represents a significant 184% increase compared to the previous quarter. The increase was primary related to the start of a new drill program at the Cumobabi property as well as confirmation drilling of the heap leach pad.

At the La Encantada Silver Mine:

• For the quarter, silver production reached 609,138 ounces representing a 62% increase over the previous quarter. The increase in silver production was due to a 43% increase in tonnes milled and a 13% increase in silver grade compared to the prior quarter.
• Silver recoveries averaged 66% during the quarter, consistent with the prior quarter, primarily due to the processing of ore with a 1% or less manganese content.
• The roasting project advanced in the third quarter with approximately 93% of the major components now manufactured. During the quarter, detailed design for the ore and reagents feeding systems as well as the roasted ore discharge system and coal storage were completed. Site preparations, including excavations and pouring of concrete pads for foundations were approximately 90% complete at quarter end. The shipment of component modules to site is expected to start in late October.
• Development and reinforcement for caving in the San Javier area was completed during the third quarter. Vertical raises are planned to be completed in the fourth quarter followed by initial production in the first quarter of 2018. The San Javier area is known to contain silver grades ranging between 150 to 200 g/t.
• A total of 1,173 metres of underground development were completed in the third quarter compared to 562 metres of development in the previous quarter. The 99% increase in development was primarily related to stope development in San Francisco dyke, San Javier and 990 areas which are known to contain higher silver grades.
• A total of 6,793 metres of exploration drilling was completed in the third quarter compared to 2,899 metres of drilling in the previous quarter.

At the La Parrilla Silver Mine:

• During the quarter, the flotation circuit processed 69,200 tonnes (752 tpd) with an average silver grade of 122 g/t and a 79% recovery while the cyanidation circuit processed 63,189 tonnes (687 tpd) with an average silver grade of 142 g/t and a 73% recovery for total production of 612,116 silver equivalent ounces.
