Great Panther Silver Updates Mineral Resources At San Ignacio Mine
July 2, 2014
VANCOUVER, BRITISH COLUMBIA--(Marketwired - July 2, 2014) - GREAT PANTHER SILVER LIMITED (TSX:GPR)(NYSE MKT:GPL) (the "Company") is providing an update to its Mineral Resources at its 100% owned San Ignacio Silver-Gold Mine in Guanajuato, Mexico (the "April 2014 Mineral Resource Estimate").
The April 2014 Mineral Resource Estimate totals 1.245 million silver equivalent ounces ("Ag eq oz") of Indicated Mineral Resources and 5.645 million Ag eq oz of Inferred Mineral Resources at a cut-off of 125 grams per tonne ("g/t") silver equivalent.
The Indicated Mineral Resource is a new addition, comprising 103,000 tonnes at 165g/t silver and 3.54g/t gold and incorporates detailed infill drilling completed in the fourth quarter of 2013 (see news release December 16, 2013), and data from mine development along the Intermediate vein. The Inferred Mineral Resource totals 737,000 tonnes at 115g/t silver and 2.04g/t gold. The breakdown for the estimate is provided in Table 1.
Table 1: Mineral Resource Estimate
|San Ignacio Mineral Resource Estimate, effective date April 6, 2014
||Ag eq g/t
||Ag eq Moz
- Base case cut-off grade of 125g/t silver equivalent
- Silver equivalent calculated using a 60 to 1 ratio of silver to gold value
- Rock Density for all veins is 2.63t/m3
- Totals may not agree due to rounding
- Grades in metric units
- Contained silver and gold in troy ounces
- Vein names abbreviated as follows: INT = Intermediate vein; DIOS1 = Nombre de Dios1 vein; DIOS2 = Nombre de Dios2 vein; and MELL = Melladito vein
Recent drilling enabled upgrading a portion of the Inferred Mineral Resource from the Intermediate vein to the Indicated Mineral Resource category. The upgrade resulted in an 18% decrease in Inferred Resources when compared to the 2012 estimate as noted in Table 2. Inferred Mineral Resources are unchanged for the Melladito and Nombre de Dios 1 and 2 veins.

The goal of recent exploration work was to increase confidence in the Mineral Resources of the Intermediate vein. The Company completed 13 infill drill holes into the vein development (see news release dated December 16, 2013) and collected 112 chip samples from 200 metres of underground mine development. Overall Mineral Resources at San Ignacio considered 91 drill holes completed between sections 450N and 1100N (up to hole ESI13-116), as well as 112 underground chip samples.
The mineralization at San Ignacio is hosted in classic epithermal quartz-calcite veins. The geologic interpretation was based on diamond drilling and surface and underground mapping. Veins were modelled to a 1.5 metre minimum width and raw assays were composited to the intersection width of the wireframes. The drill-hole and underground composites were used in the estimate of block grades using the Inverse Distance to the second power (ID2). Volumes were converted to tonnages using 2.63t/m3, which were based on results from density tests completed on 313 drill core samples captured by the wireframes.
This Mineral Resource Estimate has an effective date of April 6, 2014 and was classified as Indicated and Inferred according to the CIM Definition Standards on Mineral Resources and Mineral Reserves and is consistent with the requirements of NI 43-101. Analysis of underground mine samples and drill-core samples was performed by SGS Minerals Services in the Company's Guanajuato, Mexico laboratory.
Areas of interest for the 2014 drill program will be the extension of the drilling south along the Intermediate vein and some infill drilling on the Melladito and Nombre de Dios 1 and 2 veins.
