Great Panther Silver Signs Option Agreement to Acquire Coricancha Au-Ag-Pb-Zn-Cu Mine in Peru

GREAT PANTHER SILVER LIMITED

(NYSE MKT:

) ("Great Panther", the "Company") announces that it has signed a two-year option agreement with Nyrstar whereby the Company can acquire a 100% interest in the Coricancha Mine Complex in the central Andes of Peru, approximately 90 kilometres east of the city of Lima. The Coricancha Mine has been on care and maintenance since August 2013 and has fully permitted and operational 600 tonne per day flotation and BIOX® bio-leach plants along with supporting mining infrastructure. The property comprises more than 3,700 hectares in the prolific Central Polymetallic Belt and production at the mine dates back to 1906. Gold-silver-lead-zinc-copper mineralization (approximately 80% gold and silver) occurs as massive sulphide veins that have been mined underground by cut and fill methods. "The Coricancha option marks the beginning of an exciting new chapter in Great Panther's development as we expand into Peru, the second largest silver producing country in Latin America," stated Robert Archer, President & CEO. "Coricancha represents a near-term production opportunity and the two-year option will allow us to gain comfort with the project without having to make an immediate and significant financial commitment in the current environment of low metal prices and depressed market conditions. We intend to commence surface drilling as soon as possible, focused on defining and expanding zones of higher grade mineralization, followed by underground drilling, development, and start-up evaluations." Under the terms of the option agreement, Great Panther made an initial cash payment of US$1.5 million on signing. A second option payment of US$1.5 million is due on the first anniversary of signing to extend the option for a second year. Should Great Panther exercise the option on or before the second anniversary, an already negotiated Share Purchase Agreement would take effect whereupon Great Panther would make a cash payment of US$5 million for 100% of the shares of Nyrstar Coricancha S.A. (plus the second option payment if not already paid). Nyrstar Coricancha holds all the assets of the Coricancha Mine Complex. There is a further contingent payment of US$4 million payable to Nyrstar under certain conditions. In addition to the cash payments, the option agreement calls for exploration expenditures of US$2 million in the first year of the option and US$3 million in the second year. The Coricancha Mine Complex contains a historical Mineral Reserve and Resource Estimate (see table below) comprising a Proven and Probable Reserve of 0.64 million tonnes at a grade of 4.35 grams per tonne (g/t) gold, 149.12g/t silver, 0.32% copper, 1.77% lead and 2.60% zinc; a Measured and Indicated Resource of 0.89 million tonnes at a grade of 5.04g/t gold, 174.62g/t silver, 0.42% copper, 1.97% lead and 3.11% zinc; and an Inferred Resource of 4.88 million tonnes at a grade of 4.91g/t gold, 224.54g/t silver, 0.48% copper, 1.57% lead and 2.98% zinc. This represents 13.5 million silver equivalent ounces (Ag eq oz) in Proven and Probable Reserves, 21.96 million Ag eq oz in Measured and Indicated Resources and 124.6 million Ag eq oz in Inferred Resources. The most recently published Nyrstar Mineral Reserve and Resource Estimate for the Coricancha Mine Complex has an effective date of December 31, 2012 (see Nyrstar news release February 7, 2013 and table below). Great Panther considers this estimate as historical in nature and the reader is cautioned regarding the validity of the estimate due to the facts that 1) mining continued for 6 months after the effective date of the estimate, and 2) precious metal price assumptions used in the Nyrstar estimate were higher than current prices. Work planned by Great Panther to verify the historical estimate will include surface and underground drilling and sampling. The qualified person for Great Panther has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves, and Great Panther is not treating the historical estimate as current mineral resources or mineral reserves.

Notes: 1. Mineral resources are reported inclusive of mineral reserves. 2. Historical Estimates prepared for Nyrstar by TetraTech without technical report. 3. Metal Price assumptions (all in USD): $1,300/oz gold, $22/oz silver, $6,300/tonne copper, $2,250/tonne lead and zinc. 4. Values are rounded and may not add up exactly. 'M' indicates 'millions'. 5. The Coricancha mineral resources were estimated utilising software that incorporates vein width, length and height to estimate tonnes and assay data to estimate grade. The ore reserves were determined by the amount of directly measured information available within a block and economic viability according to metal prices and operating parameters valid at the time of the estimate. Dilution was applied to a mineral resource when the vein width was less than the projected minimum mining width, with over-dilution applied to an ore reserve according to estimated overbreak during extraction. It is not known to Great Panther what cut-off grades were used in this estimation. The 2012 mineral resource and ore reserve statement for Coricancha, with a December 31, 2012 cut-off date, was completed by TetraTech in accordance with the JORC Code (Joint Ore Reserves Committee of the Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia). 6. Silver equivalent ounces were estimated by Great Panther using the Historical Mineral Reserve and Resource Estimates. They are a guide to metal content only.
