TSX: GPR
NYSE American: GPL

VANCOUVER, Sept. 5, 2018 /CNW/ - GREAT PANTHER SILVER LIMITED (TSX: GPR; NYSE American: GPL) ("Great Panther"; the "Company") is pleased to provide an update on the progress of the trial stope and bulk sample program (the "Bulk Sample Program" or "BSP") at its 100% owned Coricancha gold-silver-lead-zinc-copper underground mine ("Coricancha") in Peru.

The BSP will process about 6,000 tonnes of material and is expected to be completed in the first quarter of 2019. Its objective is to validate key mine and process plant operating parameters used in the Company's Preliminary Economic Assessment ("PEA") announced on May 31, 2018, and further de-risk Coricancha. Following the completion of the BSP, the Company expects to make a decision in early 2019 on whether to commence the restart of Coricancha.

To date, 160 metres of decline access has been advanced, representing 35% of the project total, and is ahead of schedule. The development has reached mineralization at the Constancia vein.  The following provides a view of the Constancia Vein in the 536 cross-cut, (looking south), showing a 2.05 metre vein width grading 151g/t Ag, 6.04g/t Au, 2.94% Pb, 1.06% Zn, and 0.12% Cu. In addition, work to date has shown that resue has been effective at separating vein material from waste and controlling over-break. 

Further, the project has advanced in the following key areas:

• Successful test of the crusher has been completed
• Refurbishment of the concentrator is well advanced
• Surface roads and underground mine rehabilitation has been initiated
• 26 metres of development completed in galleries and preparations have begun for stope development

Additional information and photographs of the Coricancha Bulk Sample Program can be viewed HERE.

The Company's QA/QC program includes the regular insertion of blanks, duplicates, and standards into the sample shipments; diligent monitoring of assay results; and necessary remedial actions.  Sample assaying was completed at the independent SGS-Lima lab in Lima, Peru. The gold was analyzed by fusion with 30g fire assay and atomic absorption spectroscopy (AAS) finish, with the resulting values reported in parts per million (code FAA313). The remaining 52 elements were analyzed by mass spectrometry of inductively coupled plasma (ICPMS) and the resulting values were reported in parts per million (code IMC12B). Any gold results that exceeded the limit of detection were re-analyzed by fire assay with a gravimetric finish (code FAG303). Any silver results that exceeded the limit of detection (>10g/t) were re-analyzed by fire assay with a gravimetric finish (code FAG313). Any other metals that exceeded the limit of detection were re-analyzed by ICP-AAS (code AAS11B).
