American Sierra Gold Corp. Discovers New Gold-Rich Zone at El Rosario, Urique Project

RENO, NV--(Marketwire - November 17, 2009) - American Sierra Gold Corp. (OTCBB: AMNP), an independent gold exploration company headquartered in Reno, Nevada, is pleased to announce the discovery of a new gold-rich zone within the El Rosario mine of the Company's Urique Project, Mexico.

The highlights of the completed work program include:

- 9.74 g/t Au and 356.7 g/t Ag over 1.68 m,
- 2.16 g/t Au and 92.5 g/t Ag over 2.93 m,
- 3.60 g/t Au and 108.2 g/t Ag over 1.87 m,
- 5.65 g/t Au and 95.9 g/t Ag over 0.45 m,
- 3.69 g/t Au and 112.7 g/t Ag over 1.10 m, and
- 3.53 g/t Au and 243.1 g/t Ag over 0.40 m.

All the abovementioned results come from the underground sampling within the Rosario tunnel. This tunnel, the largest of three known workings within the El Rosario target area, was reconditioned, re-mapped and sampled in preparation for a planned underground drill program. Previously unknown extensions to the workings were encountered and sampled resulting in the discovery of the new gold-rich zone. A total of 22 samples were taken from this zone with values ranging from 0.06 to 11.57 g/t gold and 6.6 to 358.7 g/t silver.

The El Rosario target measures approximately 175 metres wide by 400 metres long and has never been drilled. It is open along strike and to depth. Multiple +1 kilogram per tonne silver assays have been collected from various veins throughout the El Rosario target. Significant silver mineralization also occurs within the altered andesite host rocks (257 g/t silver and 0.78 g/t gold over five metres), which adds to the bulk tonnage potential of the target. In 2008, surface sampling, some 150 metres above the Rosario tunnel, encountered bonanza grades of as much as 10.6 g/t gold and 8,290.0 g/t (or 241.5 ounces per ton) silver.

"We are very excited with the results of our work at El Rosario. The presence of multiple vein sets hosting high-grade silver-gold mineralization, as well as felsic intrusives related to widespread alteration and mineralization of the andesitic rocks, suggests that the El Rosario target area has the potential to expand further," commented Mr. Wayne Gruden, American Sierra's CEO.

"The new high-grade gold zone encountered may represent an ore shoot and this concept needs to be tested by drilling. We are, therefore, currently working on the preparation of an underground drilling program which we expect to initiate in the near-term and conclude in the first months of 2010," added Mr. Gruden.
