FIRST MAJESTIC ACHIEVES NEW RECORD IN SILVER PRODUCTION; PRODUCES 4.5 MILLION SILVER EQV. OUNCES IN THIRD QUARTER
First Majestic Silver Corp.'s total production in the third quarter of 2016 from its six operating silver mines reached 4.5 million silver-equivalent ounces. Total production consisted of 3.1 million ounces of silver, 14,452 ounces of gold, eight million pounds of lead and 1.5 million pounds of zinc.
"Higher silver grades, throughput rates and recoveries propelled silver production to a new company record of over 3.1 million ounces during the quarter," said Keith Neumeyer, president and chief executive officer. "We saw significant grade improvements, particularly at Santa Elena, La Guitarra and San Martin, as a result of improved mine sequencing and dilution control. Due to the improved operational cash flows, we've significantly expanded our exploration programs resulting in 19 drill rigs currently active on our properties which will allow us to release updated reserve and resource estimates for Del Toro, La Parrilla and San Martin in the first quarter of 2017. At La Encantada, detailed engineering has been completed and furnace manufacturing has started for the construction of our new roasting circuit planned for final completion in the fourth quarter of 2017."

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 838,233 tonnes, reflecting a 5-per-cent increase compared with the previous quarter. In the month of August, processing rates at Del Toro, La Parrilla, San Martin and La Guitarra were affected by the heavy seasonal rains causing temporary clogging of ore in the crushing areas.
Average silver grades in the quarter increased to 150 grams per tonne compared with 148 g/t in the previous quarter. Higher silver grades were achieved at Santa Elena, La Guitarra and San Martin due to improved mine sequencing and dilution control, offset by lower grades at La Encantada due to the blending of ore from old stopes, stockpiles and the recovery of pillars.
Combined silver recoveries averaged 77 per cent, representing a 3-per-cent increase compared with the previous quarter. La Encantada, Del Toro, La Guitarra and Santa Elena all achieved higher silver recoveries during the quarter. Furthermore, silver recoveries at Santa Elena achieved a new operating record of 91 per cent primarily due to the higher silver grades being mined from underground.
The company's underground development in the third quarter consisted of 12,764 metres, reflecting a 9-per-cent increase compared with 11,738 metres completed in the previous quarter. The company also completed 36,290 metres of diamond drilling in the quarter compared with 19,342 metres in the prior quarter, representing an 88-per-cent increase. A substantial portion of the current drilling and development is for the purpose of updating mineral reserves and resources at Del Toro, La Parrilla and San Martin. Updated National Instrument 43-101 technical reports for each of these three mining units are expected to be released in the first quarter of 2017.

At the Santa Elena gold/silver mine:
- During the quarter, Santa Elena produced 671,423 ounces of silver and
11,156 ounces of gold for a total production of 1,430,506 silver-equivalent ounces. Compared with the previous quarter, silver production
increased 11 per cent primarily due to an increase in grade and tonnage mined
from the high-grade Alejandra vein.
- During the quarter, the company modified the production split between
underground ore and the reprocessing of ore from the heap-leach pad due
to achieving higher production rates from the Alejandra vein. As a
result, production of underground ore increased to a rate of 1,750 tonnes per day while reducing heap-leach production to 1,000 tpd. This improved run
rate is expected to increase production due to the higher grades and
recoveries of underground ore.
- The mill processed a total of 241,996 tonnes, consisting of 155,552
tonnes of underground ore and 86,444 tonnes from the above ground heap-leach pad.
- Silver and gold grades of underground ore averaged 124 g/t and two g/t,
respectively. Whereas silver and gold grades from the above ground heap-leach pad averaged 43 g/t and 0.7 g/t, respectively.
- At the end of the quarter, total development of the new San Salvador
ramp reached 1,070 metres, or 47 per cent of a 2,300-metre development plan. The
new ramp will connect to the Main vein along level 575 by April, 2017.
Once the ramp is completed, it is expected to improve underground
productivity by reducing trucking bottlenecks.
- A total of 2,444 metres of underground development were completed in the
third quarter compared with 2,931 metres of development in the previous
- A total of 3,520 metres of exploration drilling were completed in the
third quarter compared with 3,509 metres of drilling in the previous
quarter. In October, the company is expected to begin a 3,000-metre
surface drilling program on the Ermitano West property. Assay results
from the drill program are expected to be completed by the end of the
At the La Encantada silver mine:
- For the quarter, silver production reached 685,478 ounces, representing a
10-per-cent increase over the previous quarter. The increase in production was
primarily due to a 19-per-cent increase in tonnes milled offset by lower silver
- Silver grades averaged 145 g/t during the quarter, or a 14-per-cent decrease
compared with the prior quarter primarily due to the blending of ore from
old stopes, stockpiles and the recovery of pillars.
- The roasting project advanced in the third quarter with the completion
of the detailed engineering design of this new circuit. Site
preparations and civil work are planned to start in the fourth quarter.
The company continues to anticipate completion of this circuit in the
fourth quarter of 2017. Once in full production, the company expects to
recover an additional 1.5 million ounces of silver per year from the
reprocessing of above-ground tailings.
- A total of 519 metres of underground development were completed in the
third quarter compared with 1,043 metres of development in the previous
quarter. The decrease in development was primarily due to limited
- A total of 3,681 metres were drilled in the third quarter, representing
a 20-per-cent increase compared with 3,062 metres in the previous quarter.
At the La Parrilla silver mine:
- During the quarter, the flotation circuit processed 93,686 tonnes (1,018
tpd) with an average silver grade of 158 g/t and an 84-per-cent recovery while
the cyanidation circuit processed 53,727 tonnes (584 tpd) with an
average silver grade of 125 g/t and a 69-per-cent recovery for total production
of 739,026 silver-equivalent ounces.
- The company is modifying the processing rates of oxides and sulphides in
order to accommodate for higher production rates from the San Marcos
mine along with lower sulphide base-metal grades. Milling rates of oxide
ore are increasing to 700 tpd (up from 500 tpd) along with a reduction of
sulphide ore to 1,000 tpd (down from 1,200 tpd). The increase in oxide
production is expected to improve the mill head grades and increase
production of silver dore bars.
- The lead circuit processed an average lead grade of 1.3 per cent with recoveries
of 78 per cent for total lead production of 2.1 million pounds, representing a
26-per-cent decrease compared with the previous quarter. The decrease in lead
production was primarily attributed to an 18-per-cent decrease in processed ore
due to the recent mill modifications.
- The zinc circuit processed an average zinc grade of 1.4 per cent with recoveries
of 53 per cent for total zinc production of 1.5 million pounds, representing a
60-per-cent decrease compared with the previous quarter. The decrease in zinc
production was primarily due to the lower circuit throughput and a 24-per-cent
decrease in zinc grades.
- Underground development completed in the quarter totalled 2,612 metres
compared with 1,834 metres developed in the previous quarter.
- A total of 5,115 metres were drilled in the third quarter, representing

an increase in underground development in the San Juan and Perseverancia
- Silver grades and recoveries improved during the quarter, averaging 195
g/t and 82 per cent, respectively.
- Lead grades and recoveries averaged 5.0 per cent and 66 per cent, respectively,
producing a total of 5.9 million pounds of lead, consistent with the
- Underground development completed in the quarter totalled 2,328 metres
compared with 1,754 metres developed in the previous quarter.
- Total exploration metres drilled in the quarter amounted to 6,643
metres, representing a 101-per-cent increase compared with 3,306 metres drilled in
the previous quarter.
At the San Martin silver mine:
- During the quarter, San Martin produced 500,441 ounces of silver and 907
ounces of gold for a total production of 562,096 silver-equivalent
ounces. Silver production increased 22 per cent compared with the prior quarter
primarily due to a 12-per-cent increase in silver grade and an 8-per-cent increase in
- Silver grades and recoveries averaged 246 g/t and 84 per cent, respectively,
during the quarter. In addition, gold grades and recoveries averaged 0.4
g/t and 85 per cent, respectively. The higher silver grades were primarily the
result of higher production rates from the Rosarios and Veladora veins.
- Detailed engineering work for the installation of the tailings filter
presses was completed during the quarter. Ground preparations including
the installation of the foundations are expected to begin in late
October. The filter presses, which are designed to recover and reuse
solution and to save on water consumption, are expected to be installed
and undergo testing in the first quarter of 2017.
- Following successful lab tests, the company is planning to install
oxygen injectors and lead nitrate into the processing leach tanks over
the next six months. Lab results indicate the potential for a 2-per-cent
increase in metallurgical recoveries by using these reagents.
