EL GALLO RETURNS DEEPEST HIGH-GRADE INTERCEPT

20.8 OPT SILVER OVER 14.3 FT

TORONTO, ONTARIO (MARCH 18, 2009)  US GOLD CORPORATION (NYSE Alternext:UXG) (TSX:UXG) (FRANKFURT:US8) is pleased to announce that core drilling at the El Gallo project in Sinaloa State, Mexico, has returned the deepest high-grade silver intersection to date. Testing below the previous limits of the mineralization returned: 20.8 ounces of silver per ton (opt) (713.1 grams per tonne (gpt)) over 14.3 feet (ft) (4.4 meters (m)).

Hole GAX012 intersected two separate zones of high-grade silver mineralization, with the deepest being at a vertical depth of 380.0 ft (115.0 m). The deepest intersection was the most significant with an average grade of 20.8 opt silver (713.1 gpt) over 14.3 ft (4.4 m), including 73.8 opt silver (2,530.0 gpt) over 2.5 ft (0.8 m). This intersection extended mineralization vertically by 65.0 ft (20.0 m).

The second shallower high-grade intersection returned 16.8 opt silver (574.4 gpt) over 13.0 ft (4.0 m) at 150.0 ft (46.0 m) and is believed to be part of a separate parallel vein (Figure 1) situated south of the deeper intersection.

The remaining four core holes were drilled primarily to delineate and extend the mineralization that was initially indentified in the upper portion of the veins through conventional rotary drilling. These core holes will help form the basis of an initial NI 43-101 resource estimate.  On-going core drilling is designed to intersect possible cross structures and new parallel veins to the north.

(1)Numbers may not balance due to rounding

Since January US Gold has completed a total of 13 core holes at El Gallo (for a list of all hole locations and reported intersections see Figure 2 and Appendix 1) with core and conventional rotary drilling returning high-grade along a strike length of 1,475.0 ft (450.0 m) and to a depth of 380.0 ft (115.0 m). Mineralization remains open to further expansion and the presence of parallel veins containing high-grade silver intercepts is encouraging.

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.

Samples from the core drilling were split on-site at the Magistral Mine property.  One quarter of the split drill core was shipped to ALS Chemex in Hermosillo for sample prep and analysis by 4-acid digestion with ICP determination for silver and fire assay for gold. Samples returning greater than 1500 ppm silver or 10 ppm gold were re-analyzed using gravimetric fire assay. Standards and blanks were inserted every 25 samples.

All holes were drilled with HQ bits utilizing a CS-1500 truck-mounted core drill. Samples were taken based on lithologic and/or mineralized intervals and vary in length. The true width of the mineral zone has not yet been determined.  For the purposes of this news release “high-grade” is defined as 14.6 opt silver (500.0 gpt) or greater.
