Trench Samples Return up to 888 g/t Silver and up to 9.95 g/t Gold and
Define Drill Targets at the Sandra Project in Durango State, Mexico
March 22, 2006
Vancouver, March 22, 2006 - Canasil Resources Inc. (Canasil, TSXV: CLZ) announces that results of trench sampling at the Sandra project in Durango State, Mexico, confirm silver and gold mineralization observed in earlier surface samples from the Barite, Maria Fernanda, and Encino veins. Assay results returned silver grades of up to 888 g/t (25.9 oz/t) silver over 0.7 metres at the Barite vein, and up to 9.95 g/t (0.29 oz/t) gold and 365 g/t (10.65 oz/t) silver over 0.5 metres at the Maria Fernanda vein, where trench samples indicate consistent silver/gold mineralization over a strike length of approximately 300 metres..
These results now confirm and define targets for drilling at the Sandra project in order to explore extensions of these veins along strike and at depth. The silver and gold grades observed in samples taken across the entire width of the mineralized structures are encouraging because they confirm the high grades seen in the earlier surface sampling program.
The mineralized veins and structures identified by the earlier geologic mapping and surface sampling program (announced on November 2, 2005) were tested by trenches cut to expose the vein mineralization at approximately 25 - 50 metre intervals, depending on access and terrain. Samples were taken across the mineralized vein, the hanging wall and the footwall for analysis and interpretation. The results from samples taken from the Barite, Maria Fernanda, and Encino veins are presented below:
Barite Vein:
Six trenches were cut over the surface projection of the Barite structure along a strike length of over 200 metres. Only two trenches cut the vein, separated by a distance of approximately 40 metres. The other trenches exposed peripheral alteration zones but did not reach the vein structure. Samples from the vein returned high silver values up to 888 g/t silver (25.9 oz/t silver) over 0.7 metres, and 373 g/t silver (10.88 oz/t silver) over 2.0 metres. The mineralized widths and high silver grades observed are very encouraging for future drilling to test this structure at depth.

Maria Fernanda Vein:
A total of 21 trenches were cut over the Maria Fernanda vein and its branches along a surface strike length of approximately 400 metres. While the average width of the vein was relatively narrow (0.30 to 1.0 metres), assays returned significant silver/gold mineralization over a strike length of over 300 metres. Several trenches returned high silver and gold values, up to 406 g/t (11.84 oz/t) silver and 1.22 g/t (0.036 oz/t) gold over 0.7 metres, and 365 g/t (10.65 oz/t) silver and 9.95 g/t (0.29 oz/t) gold over 0.5 metres. These results indicate that the Maria Fernanda vein is a strong mineralized structure carrying silver and gold, and drill testing will be required to test the width of the vein, grades and strike length at depth.

Encino Vein:
The Encino vein structure is buried under 2 –5 metres of overburden. The vein was observed in a dry streambed, where the overburden has been stripped. Initial sampling of this structure returned silver values up to 113 g/t (3.30 oz/t) silver over 4.7 metres (reported on November 2, 2005). The trenches cut to intersect the Encino vein did not reach the vein due to the depth of the overburden. However the exposed alteration zone confirmed the wide structure observed earlier, and returned anomalous silver values. The Encino structure shows potential for a wide, and possibly large, mineralized structure with lower silver grades than those observed at the Maria Fernanda and Barite veins. Drilling will be required to explore this structure below the overburden cover.

The strong mineralized structures identified by the earlier geologic mapping and surface sampling program, and now confirmed by the trenching program, have defined drill targets for future exploration at the Sandra project. The Company plans to prepare a drill program at the Sandra project, which will form part of the Company's plans to arrange additional financing to fund drill programs on its silver/gold exploration projects in Mexico.
The trenching program was supervised and carried out by the Company's wholly owned Mexican subsidiary, Minera Canasil S.A. de C.V. Samples were prepared on site and shipped to the ALS Chemex laboratories in Hermosillo, Mexico, for preparation and on to the ALS Chemex laboaratories in Vancouver for analysis by ICP for multiple elements and fire assay for gold and silver. The trenches were inspected after the completion of the program and check samples collected and sent for analysis at the SGS laboratories in Durango, Mexico, for comparison with the trench sample results. Gary Nordin, P.Geo. British Columbia and Director of Canasil, is the qualified person for this project in accordance with National Instrument 43-101.
