Great Panther Silver Reports Second Quarter 2017 Production Results

July 13, 2017

GREAT PANTHER SILVER LIMITED (TSX: GPR; NYSE MKT: GPL) (“Great Panther”; the “Company”) announces production results for the second quarter (“Q2”) 2017 from its two wholly-owned Mexican silver mining operations: the Topia Mine in Durango and the Guanajuato Mine Complex (“GMC”), which includes the San Ignacio Mine.

Second Quarter 2017 Production Highlights (Compared to Second Quarter 2016)

“Great Panther had an excellent second quarter, setting a new Company record for consolidated metal production and a new record for metal production in Topia,” stated Robert Archer, President & CEO.  “I would like to congratulate our entire operations team, especially in Topia, for all their hard work and efforts in achieving this quarter's milestones.”

(1) Silver equivalent ounces for 2017 were calculated using a 70:1 Ag:Au ratio, and ratios of 1:0.0559 and 1:0.0676 for the price/ounce of silver to price/pound of lead and zinc, respectively.

(2) Silver equivalent ounces for 2016 were calculated using a 70:1 Ag:Au ratio, and ratios of 1:0.0504 and 1:0.0504 for the price/ounce of silver to price/pound of lead and zinc, respectively.

(3) The Topia processing plant was shut down for upgrades in Q1 2017 and so had no production during that period.

Guanajuato Mine Complex

In Q2 2017, metal production at the GMC was 2% lower than the previous quarter, and decreased by 8%, to 715,423 Ag eq oz, when compared to the same quarter in the previous year.  The decrease was attributed to lower tonnes milled from San Ignacio, combined with lower overall grades, mainly reflecting variability in the mineral resource.  Additional exploration drilling and development is being undertaken to improve the resource definition in these areas.

San Ignacio accounted for 55% of the total ore processed at the GMC in Q2 2017, compared to 62% in Q2 2016.  The decrease partially accounted for the lower average gold grades as San Ignacio has a higher gold:silver ratio.  The increase in the proportion of production from the Guanajuato mines partially compensated for the decrease from San Ignacio and resulted in the higher metallurgical recoveries.

Exploration drilling increased during the second quarter of 2017, compared to the previous quarter, with a focus on enhancing ore zone definition and increasing mineral resources.  Following the encouraging indications from the drilling program at San Ignacio (announced on June 19, 2017), exploration development and drilling along strike of the current workings were fast-tracked with the objective of better defining the newly-identified mineralization.

Topia Mine

Milling operations returned to design capacity in the second quarter of 2017, following the commissioning of the new tailings handling facility and the upgraded processing plant.  The operation is now producing exclusively dry tailings through the new filtration plant.  All tailings are being deposited on the Phase I Tailings Storage Facility (“TSF”) while the Company continues its efforts to obtain the Phase II permit from SEMARNAT (the Mexican environmental permitting agency).  

Topia achieved a record 386,867 Ag eq oz in metal production, reflecting an increase of 47% compared to the second quarter of 2016.  This was attributed to a combination of higher tonnes milled, higher grades of feed material and improved recoveries.  The increase in tonnes milled reflects maximizing the plant capacity by processing a controlled blend of run-of-mine production and ore stockpiled during the scheduled plant shutdown.  The improved metallurgical recoveries were attributed to improved control over the mill feed and head grade, coupled with the recent plant upgrades.  The increase in grades was due to a greater focus on selective mining, dilution control and ore sorting.

The Company is maintaining its guidance of 4.0 – 4.1 million Ag eq oz (based on a 70:1 silver:gold ratio) for 2017 and continues to believe that it will be able to obtain a permit for the Phase II tailings facility at Topia without interruption of operations.  However, the deposition of dry tailings on the Phase I TSF cannot continue indefinitely and the Company cannot provide complete assurance that a disruption can be avoided.  Discussions to date with the authorities and other stakeholders have been positive and are continuing.

The Company is also maintaining its previously issued cash cost and all-in sustaining cost (“AISC”) guidance for 2017 of US$5 – 6 per payable silver ounce, and US$14 – 16 per payable silver ounce, respectively[1]

There is a risk that guidance will be affected if the Company is unable to obtain a permit for the Topia Phase II TSF on a timely basis or at all.  In the event there is a significant change to the Company's production guidance expectations, the Company will provide a timely update to the market.

The previously announced acquisition of the Coricancha Mine Complex (“CMC”) in Peru, currently on care and maintenance, was completed effective June 30, 2017.  The Company’s plans include further evaluations of the mine and processing infrastructure, mine rehabilitation and development in preparation for underground drilling, environmental studies, and the initiation of a preliminary feasibility study ("PFS").  Depending upon the outcome of the PFS, capital investments in support of restarting operations could commence in 2018.  The Company is currently working on an updated mineral resource estimate for the Coricancha Mine, which is expected to be completed towards the end of the third quarter of 2017.
