Canplats Resources Corporation: Positive Initial Metallurgical Results From Camino Rojo Project | |
VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 19, 2009) - Canplats Resources Corporation (TSX VENTURE:CPQ) is pleased to announce the results of 18 column leach tests from the Represa Zone at its 100% owned Camino Rojo project located in the State of Zacatecas, Mexico. These test results indicate that near-surface oxide mineralization at the Represa Zone is amenable to simple and cost effective heap leach processing methods. Highlights of the column leach tests indicate: - Gold recoveries are relatively insensitive to crush size and average 76% for oxide mineralization at a comparatively coarse 3/4 inch feed size; - Gold recoveries of up to 62% from transitional oxide/sulphide mineralization; and - Moderate cyanide and lime consumption. The column tests were completed by SGS Minerals Services in Durango, Mexico, a subsidiary of SGS Lakefield Research Laboratory. Column tests were conducted over a 95 day period using samples from large diameter drill core crushed to feed sizes varying from 1 1/2 inches to 3/8 inches.

Mineralization remains open for further expansion in both strike directions and to depth. Reconnaissance exploration is underway to identify new target areas within the 340,000 hectare (more than 1,300 square mile) Camino Rojo property. The Represa Zone is situated in flat terrain within an area of excellent infrastructure, less than 5 kilometers from a paved highway and high voltage power lines. It is located 50 kms to the southeast of Goldcorp's large-scale Penasquito Mine. Ken McNaughton, P.Eng., is the qualified person responsible for the Camino Rojo exploration program. |
