New Gold Rich Zone At El Rosario Target

New Gold Rich Zone At El Rosario Target

VANCOUVER – Yale Resources Ltd., on behalf of its partner, American Sierra Gold Ltd., reported the discovery of a new gold-rich zone within the underground workings of the El Rosario Target in the Urique Project, Chihuahua State, Mexico.

The new gold zone was found within a previously unknown extension to the El Rosario tunnel during a program that included reconditioning, mapping and sampling in preparation for a planned underground drill program. The Rosario tunnel is the largest of three known workings within the larger El Rosario target area.

This gold-rich zone may represent a ‘clavo’, or ore shoot, and is approximately 60 metres long. A total of 22 samples were taken in the zone with values ranging from 0.06 to 11.57 g/t gold and 6.6 to 358.7 g/t silver.

Sampling of the veins underground was limited by the narrow width and size of the workings, however surface sampling some 150 metres above the Rosario tunnel, encountered bonanza grades up to 10.6 g/t gold and 8,290.0 g/t (or 241.5 ounces per ton) silver (see news release dated February 6, 2008) within 10 to 40 cm wide veins that make up vein-sets that have been mapped as being 1 to 7 metres wide.

At El Rosario fieldwork in 2008 identified at least five vein-sets hosted within altered andesite. Multiple +1 kilogram per tonne silver assays have been collected from various veins throughout the El Rosario target. Significant silver mineralization of up to 257 g/t silver and 0.78 g/t gold over five metres also occurs within the altered andesite host rocks, which adds to the bulk tonnage potential of the target.

The El Rosario target, as currently defined, measures approximately 175 metres wide by 400 metres long. The mineralization and alteration mapped on surface and underground is open along strike and to depth and has never been drilled.
