EXPLORATION NEWS RELEASE

THREE GOLD VEINS DISCOVERED NEAR

US GOLD’S EL GALLO PROJECT

7.7 gpt Gold over 4.8 m, Including 22.2 gpt Gold over 1.1 m

TORONTO, ONTARIO (DECEMBER 8, 2010) US GOLD CORPORATION (NYSE: UXG) (TSX: UXG) is pleased to announce the discovery of three gold-bearing veins near the company’s El Gallo Project in Sinaloa state, Mexico (Fig. 1). The three veins, which to date have been defined by a total of 17 core holes, are all located within hauling distance of El Gallo. These new veins will not be included in the upcoming Preliminary Economic Assessment.

“The discovery of these veins illustrates the exploration potential of US Gold’s large land package around El Gallo.  Follow-up drilling has commenced with the objective of further extending the mineralization. Seven drills are currently operating at the project and we expect this pace to continue throughout 2011,” stated Rob McEwen, Chairman and CEO.

Drill Assay Highlights

The drill assay results shown below are selected assays from the three new veins. Complete results are listed in Table 1. Vein locations are shown in Figure 1.

Gold Zone Vein (2 core holes drilled — 500 meters SE of El Gallo)

Current Known Strike Length 50 m (Fig. 2)

·                  GZX-002: 7.7 gpt gold over 4.8 meters, including 22.2 gpt gold over 1.1 meters

·                  GZX-001: 6.4 gpt gold over 3.1 meters, including 10.8 gpt gold over 1.2 meters

Alamo Vein (10 core holes drilled — 7 km North El Gallo)

Current Known Strike Length 450 m (Fig. 3)

·                  SJX-002: 9.3 gpt gold over 1.7 meters

·                  SJX-008: 7.8 gpt gold over 0.8 meters

·                  SJX-009: 7.6 gpt gold over 1.7 meters

·                  SJX-010: 4.2 gpt gold over 6.0 meters, including 7.9 gpt gold over 1.4 meters

Oro Vein (5 core holes drilled — 32 km NE of El Gallo)

Current Known Strike Length 90 m

·                  POX-002: 7.4 gpt gold over 0.9 meters

·                  POX-003: 5.9 gpt gold over 0.9 meters

The Alamo and Oro veins were historically mined underground on a limited scale. Mining targeted the upper portion of the vein that appears at the surface. Underground sampling on the veins produced encouraging values for gold and was followed-up with the drilling described above.

The El Gallo Gold Zone vein was initially discovered by a US Gold prospector in late 2008, but delays in permitting didn’t allow the area to be drill tested until recently. Similar to the El Gallo silver discovery located 500 m to the northwest (Fig 1, 2), no previous mining is evident in the area.

Each of the three gold veins appears to have the potential to extend at depth and laterally. In addition, several other gold and silver veins have been discovered through prospecting and geological mapping. Drilling has commenced on these new veins as well.

QUALIFIED PERSON

This news release has been viewed and approved by John Read, CPG, US Gold’s consulting 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 Company’s Magistral Mine property.  One quarter of the split drill core was shipped to ALS Chemex in Hermosillo for sample preparation and analysis by 4-acid digestion with ICP determination for silver and fire assay for gold. Samples returning greater than 10 ppm gold were re-analyzed using gravimetric fire assay. Standards and blanks were inserted every 20 samples.

All holes were drilled with HQ bits and reduced to NTW where required. 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.
