Yale Resources Ltd. (TSX-V - YLL and Frankfurt - YAB), on behalf of its partner, American Sierra Gold Ltd., announces the discovery of a new gold-rich zone within the underground workings of the El Rosario Target in the Urique Project, Chihuahua State, Mexico.

Highlights from the underground sampling within the Rosario tunnel include:
- 9.74 g/t gold and 356.7 g/t silver over 1.68 m,
- 2.16 g/t gold and 92.5 g/t silver over 2.93 m,
- 3.60 g/t gold and 108.2 g/t silver over 1.87 m,
- 5.65 g/t gold and 95.9 g/t silver over 0.45 m,
- 3.69 g/t gold and 112.7 g/t silver over 1.10 m, and
- 3.53 g/t gold and 243.1 g/t silver over 0.40 m.

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 (see news release dated August 26, 2008), 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.

The presence of multiple vein sets hosting high grade silver-gold mineralization, as well as felsic intrusives that appear to be related to widespread alteration and mineralization of the andesitic host rocks, suggests that the El Rosario target area has the potential to be further expanded.

Samples were prepared and analyzed by IPL Inspectorate in their facilities in Mexico and Vancouver, respectively. Samples generally consisted of 1-3 kg of material. Gold and silver analyses were performed by 30 gram fire assay with an AA finish. Samples with greater than 1 g/t gold were re-assayed using gravimetric methods.
