Great Panther Receives NI43-101 Resource Estimate for Topia Mine
VANCOUVER, BRITISH COLUMBIA -- (MARKET WIRE) -- December 28, 2006 -- GREAT PANTHER RESOURCES LIMITED (TSX: GPR) is pleased to announce that Wardrop Engineering (Wardrop) of Vancouver, B.C. has delivered a NI43-101 compliant resource estimate for the Company's Topia Silver-Lead-Zinc Mine in northwestern Durango State, Mexico. Using a US$60 Gross Metal Value (GMV) cut-off grade, Wardrop estimates that the Animas, Argentina, La Dura, and Madre veins, plus several parallel veins (categorized as 'other') together contain a Measured Mineral Resource of 53,500 tonnes grading 493g/t silver (Ag), 0.882g/t gold (Au), 4.89% lead (Pb), and 4.44% zinc (Zn), with a GMV of US$256 per tonne, an Indicated Resource of 111,500 tonnes grading 473g/t silver, 0.860 g/t gold, 4.86% lead, and 4.53% zinc, with a GMV of US$253 per tonne, and an Inferred Mineral Resource of 71,700 tonnes grading 443g/t silver, 0.686 g/t gold, 4.31% lead, and 4.02% zinc, with a GMV of US$229 per tonne. GMV was calculated using average October 2006 metal prices as noted at Kitco.com, an estimated dilution of 33%, and payable metal recoveries as noted below. The US$60 GMV cut-off grade was derived from estimated mining and milling costs of US$45/tonne, concentrate shipping cost of US$5/tonne, and US$10/tonne overhead cost. The resource was prepared by Ordinary Kriging and carried out in 3 passes. Specific Gravity (SG) for the veins was estimated by inverse distance weighted to the second power.
