Canasil Resources has announced that it has identified an important fresh silver zone at the Sandra-Escobar project, located in North Durango State of Mexico.
Geological mapping and surface sampling program, carried out recently, has defined a 600x200 m of stockwork and dispersed silver mineralization zone, which is situated 3 km towards the southeastern part of the San Francisco and Candelaria silver vein breccias, which were previously drill tested.
The company encountered more than 250 g/t silver from 16 samples out of 21 gathered from mineralized dumps and narrow veins in this zone, more than 500 g/t silver from eight samples, and more than 1,000 g/t silver from four samples. This zone is related to a structural corridor, trending towards northwest and southeast, and a small resistivity anomaly, which was interpreted from the ZTEM aerial geophysical survey carried out during 2011. The company has outlined this presumed silver trend for more than 3 km from the San Francisco and Candelaria vein breccias, wherein 19 g/t silver over 52.5 m was intersected from the hole SE-11-11. This zone will be outlined through a ground geophysical survey and additional rock sampling program.
Narrow carbonate-barite veins contain the mineralization in this zone. Ten samples of vein material included silver between 19 g/t to 1,465 g/t silver. Two vuggy porous volcanic tuff host rock samples outside the veins yielded silver grades of 53 g/t and 57.8 g/t.
