PROMONTORIO - Silver Price Sensitivity Analysis Further Supports 60+ Million Ounce Silver Equivalent Resource on Promontorio Silver Project in Sonora, Mexico
Kootenay Silver Inc. (TSX VENTURE: KTN.V) is pleased to report the Company has completed a sensitivity analysis of varying metal prices at 18, 24 and 36-month trailing averages, further supporting the recent updated NI 43-101 resource estimate conducted on the Company's flagship Promontorio Silver Project in Sonora, Mexico.
An industry standard, 18 month trailing average was used in the NI 43-101 Resource estimate recently completed by SRK Consulting (U.S.) Inc. as reported August 21, 2012.
States Kootenay President and CEO James McDonald "When you apply even the most conservative metal prices observed during the 18 to 36 month period, there is less than a 4% variance in Promontorio's measured and indicated resource. This is due to the impact of the high silver grades in the diatreme system, which is also exciting as it has a positive impact on the economic dynamics of the resource. Moreover, using the lowest metal prices observed over the three-year period, Promontorio still maintains a benchmark measured and indicated silver equivalent resource totaling over 60 million ounces."
