US Gold Corporation: El Gallo Initial Metallurgical Results

Overall Recoveries Average 90%
Low Grade Mineralization Recoveries Average 96%

TORONTO, ONTARIO--(Marketwire - 08/26/09) - US GOLD CORPORATION (AMEX:UXG - News)(TSX:UXG - News) is pleased to announce that preliminary metallurgical testing on El Gallo silver mineralization has returned excellent recoveries, averaging more than 90%. Silver recoveries from lower grade samples averaged 96%.

PHASE ONE - METALLURGICAL TESTING

Phase one metallurgical testing at El Gallo consisted of 10 samples collected from HQ-size drill core (2.5 inch or 6.4 cm diameter). Testing was completed on: 1) high-grade sulphide mineralization, 2) low-grade sulphide mineralization, and 3) a mixture of oxide and transitional oxide-sulphide mineralization. Tests were supervised by Juvencio Mireles Ortiz, Metallurgy Manager, SGS de Mexico S.A. de C.V. located in Durango, Mexico, along with consultation services provided by Richard Addison, P.E., Principal Process Engineer, Pincock Allen & Holt of Denver, Colorado. Results from these tests are listed below:

(i) 80% passing -200 mesh is a description of the grind size of the sample
employed in the test. Specifically it means 80% of the sample by weight
passed through a -200 mesh screen (hole size in screen: 75 micrometers).

PHASE TWO - PLANNED METALLURGICAL TESTING

The second phase of metallurgical testing at El Gallo will consist of bulk sampling that utilizes slurry leaching for the high-grade mineralization. Lower-grade mineralization will undergo a series of column leach tests to help determine the viability of using a heap leach recovery process. Due to the time required for completion of the necessary column testing (approximately 20 weeks), the initial resource estimate for El Gallo is now scheduled to be released during the first quarter of 2010. This development, despite delaying the pending resource estimate, could potentially have a positive impact on the economics and project size at El Gallo.

QUALIFIED PERSON

This news release has been viewed and approved by Steve Brown, US Gold's Chief Geologist, who is a Qualified Person as defined by National Instrument 43-101 and is responsible for program design and quality control of exploration undertaken by the Company at its Mexican exploration properties.

All holes were drilled with HQ bits utilizing a CS-1500 truck-mounted core drill. Samples for Phase 1 metallurgical testing were chosen as nominal 7 kg composites of individual adjacent drill samples based on parameters of grade and oxidation characteristics. Samples were taken from either HQ core or bulk rejects from the corresponding core sample intervals. In the case of core composites, entire intervals of 1/2 core were taken, leaving nominal representative pieces in the core box. For bulk reject composites, entire rejects were composited. Composites were sent to SGS de Mexico S.A. de C.V. in Durango, Mexico for testing under the direction of Juvencio Mireles Ortiz, Manager of Metallurgy. Metal recovery determinations were done by bottle-roll analysis using variable grain size, cyanide concentrations and leach times.
