American Sierra Gold Samples 428 G/T Gold And Plans To Commence Production Test At Discovery Day Project

RENO, NEVADA - MAY 6, 2010 - American Sierra Gold Corp. (NASDAQ OTC BB: AMNP), an independent gold exploration company headquartered in Reno, Nevada, is pleased to announce results of the on-going sampling program at its Discovery Day Gold Property and the planned commencement of a production test run.

During the period of March 23 to April 16 geological crews conducted systematic sampling at three underground locations in the Discovery Day mine. A total of 29 samples were taken at the "490" raise, "400" raise and at the end of the 72 crosscut. These three potential mining targets show strong structural anomalies with significant quartz veining. The sampling program was designed to determine ore grades and mining widths of these zones in order to evaluate production mining economics.

Economically feasible assay results were obtained from both the "490" and "400" raises and are shown in the table below. Thirteen of the fifteen samples taken in the "72 crosscut" carried gold values but all assays were below the mining cut-off grade of 0.5 ounces per ton.

SAMPLE #	SAMPLE DESCRIPTION	Au OPT

400 R	Chip sample across 40 in. of entire structure	1.02
400 R-1	Chip sample across 26 in. vein width at top of raise	4.52
400 R-2	Chip sample across left 4 in. quartz section of 400 R-1	0.78
400 R-3	Chip sample across 18 in. vein width at bottom of raise	13.78
400R - 1A1	Grab sample from muck pile	1.20
400R - 1A4	Repeat check assay of sample 400R-1A4	1.18
400R - 1B1	Chip sample of spider quartz	Trace
490R - 4A1	Channel cut across 11 ft. of face	1.52
490R - 4B1	Grab sample from muck pile at face	0.23
490R - 4C1	Mix of quartz matrix over 4-5 ft. width	0.33
490R - 4D1	Left 2 ft. section of 490-4A1	2.04
490R - 4E1	Greenstone wall rock left of vein	Trace
490R - 4F1	Greenstone wall rock	Trace
490R - 4G1	Silicified shale wall rock to right of vein	0.05

These samples came from the two raises that are located up dip on the same structure that 1996 mill reports document having produced 195 tons of ore that averaged 12.06 oz/ton. This included 43 tons of bonanza grade ore averaging 37.4 oz/ton. This single 10-day production run reportedly resulted in the production of over 2,300 ounces of gold worth over $2.6M at today's gold prices.

According to mine manager Patrick Fagen, "These assay results support good continuity of values between the two zones indicative of an extension of the previously mined ore shoot. The grades are exceptional and the structure appears to be widening both up dip and along its southern strike. Further drifting at both locations is needed to determine the full extent of the ore bodies."

American Sierra Gold's President Wayne Gruden added, "These encouraging assay results have prompted a company decision to focus immediate efforts on a production test run to accurately determine the feasibility of mining this past producing zone and test our mill. We plan to conduct this production test concurrently with an underground core drilling program." Both work programs are scheduled to commence during the month of May.
