Canasil Defines New High-Grade Silver Veins at La Esperanza Project in Durango/Zacatecas States, Mexico
July 28, 2010
Vancouver - Canasil Resources Inc. (Canasil, TSX-V: CLZ) announces that a recently completed geological mapping and surface sampling program in the northwest area of the Company’s La Esperanza Silver project in Durango and Zacatecas States, Mexico, has defined several high-grade silver veins with a combined strike length of over 1.5 kilometres. The vein outcrops are located on the recently extended northwest zone of the 19,000 hectare project area, approximately 10 kilometres along strike northwest of the La Esperanza vein. The Company collected 37 rock chip and dump samples from the vein outcrops and from adjacent dumps of mineralized material left over from past artisanal mining activity. The table below provides details of significant samples for reference:

The results confirm the reports of silver bearing veins in the new claim areas with significantly higher grades than historical reports indicated. The location of these vein outcrops with respect to the La Esperanza vein, located 10 kilometres to the southeast and which has been previously drilled returning high-grade silver intercepts over wide widths as previously reported and detailed below, indicates the potential for identifying further buried silver bearing veins over the very extensive project area. The occurrence of several high-grade silver samples with over 250 g/t silver from the veins and dumps is particularly encouraging.
The La Esperanza project is located in the Chalchihuites district in northern Zacatecas and southern Durango States. This recognized silver district hosts a number of active mines such as Pan American Silver’s La Colorada and First Majestic’s La Parrilla silver-lead-zinc mines. The Company has increased the claim area at the La Esperanza project to 19,011 hectares. The claims now cover the prospective SE-NW trend where significant alteration is observed along over 4 km strike extensions of the La Esperanza vein. The La Esperanza vein outcrops over a strike distance of 300 metres and has been drill tested with 9 diamond drill holes for a total of 1,422 metres. As previously reported, the drilling intersected a high grade epithermal vein shoot with an average grade of 396 g/t silver, 0.71% zinc and 1.96% lead over a true width of 10.30 metres. The extensive alteration zones observed around the La Esperanza vein and surrounding structures together with the newly identified vein system in the northwest zone of the project area indicate a possibility of a district scale epithermal silver vein system.
The surface sampling and geological mapping program was supervised and carried out by the Company's wholly owned Mexican subsidiary, Minera Canasil S.A. de C.V., under the direction of Erme Enriquez CPG, Director of Exploration and Development. Samples were sent to ALS Chemex Laboratories in Zacatecas, ZA Mexico, for preparation and on to ALS Chemex in North Vancouver, B.C. Canada for assay analysis for gold and silver by fire assay with an atomic absorption finish (“FA-AA”) on a 30 gram split, and for copper, lead and zinc by digestion of 1.00 gram sample in aqua regia and analysis by AA. Gary Nordin, P. Geo. British Columbia and Director of Canasil, is the designated Qualified Person for this project in accordance with National Instrument 43-101.
