TORONTO, ONTARIO (March 8, 2011) US GOLD CORPORATION (NYSE: UXG) (TSX: UXG) is pleased to announce continued exploration success at and surrounding the company’s El Gallo project in Sinaloa State, Mexico (Fig. 1). Drilling continues to expand the size of the silver-gold resources and further delineate the mineralization associated with the recently discovered veins. In addition, exploration has intersected near surface, bulk tonnage mineralization in a new area.

EL GALLO AND DISTRICT EXPLORATION

US Gold’s exploration at and around El Gallo is focused on: 1) increasing the size of the silver-gold resources, 2) upgrading inferred mineralization to the measured and indicated categories, 3) delineation of new veins around El Gallo in order to include them in the updated resource estimate, and 4) discovering El Gallo style mineralization

within hauling distance of the proposed process facilities. Nine drills are operating at the project and four more are scheduled to arrive in the coming weeks. US Gold has budgeted $15 million for drilling in Mexico during 2011.

El Gallo Mineralization Expanded in Multiple Directions (Fig. 1 and 2)

Drilling at El Gallo is focused on growing the size of the resource and infilling select areas of the deposit. The expansion holes successfully extended the known mineralization 60 meters east and 50 meters to the southeast. The potential to further extend the mineralization in each of these directions looks encouraging. Follow up drilling is in progress.

The infill drilling, which continues to meet expectations, was designed to upgrade inferred mineralization to the measured and indicated categories for feasibility study purposes.

Alamo Vein — High Grade Gold Encountered at Depth (Fig. 1 and 3)

Alamo is one of several new veins that were discovered late in 2010. The initial holes released in December returned encouraging results such as 9.3 gpt gold over 1.7 meters and 7.6 gpt gold over 1.7 meters. Follow-up drilling has successfully extended the higher grades by 30 meters at depth. The zone has been extended from surface to 125 meters and indentified over a strike length measuring 550 meters.  Highlights from the drilling are shown below

Chapotillo — Near Surface Mineralization Expanded (Fig. 1)

Since returning positive drill results in 2010, exploration has been focused on extending the near surface mineralization.  Drilling 50 meters east and up-dip of the known mineralization continues to show the zone is expanding in size.  Mineralization encountered in the most recent holes remains near surface and there appears to be good expansion potential. On-going drilling will continue to test for possible extensions. US Gold plans to incorporate Chapotillo in the next updated resource.

In addition, hole GAX-023 successfully tested a geochemical anomaly 700 meters to the southeast. This result highlights further upside potential at Chapotillo.

Haciendita — New Discovery Showing Bulk Tonnage Potential

Drilling 10 km north of El Gallo has returned wide intersections of lower grade on a new prospect called Haciendita. A total of 10 holes were completed over an area 100 meters x 150 meters. The average grade weighted average of these holes was 0.9 gpt gold and 17.4 gpt silver over 15.7 meters, occurring approximately 25 meters below surface.  US Gold believes Haciendita has good potential:  1) the mineralization is near surface and shallow dipping, 2) the zone is open and appears to be thickening to the east, and 3) the area could potentially be mined by open pit and transported to the planned heap leach facility at El Gallo.

Eight additional holes are currently being drilled. Should the results meet expectations, US Gold will begin a series of column tests to determine the ores leachability. Gold deposits in Mexico of similar grade and depth have proven to be low cost operations (Goldcorp’s Los Filos Mine — 0.6 gpt gold and Capital Gold’s El Chanate Mine — 0.7 gpt gold).

Feasibility Study and Permitting Update

Since releasing the El Gallo Preliminary Economic Assessment on February 7th, US Gold has advanced work related to the projects feasibility study and mine permitting.

a)              Feasibility Study

·                  Ausenco Solutions Canada Inc. from Vancouver have been contracted to assist with developing the El Gallo feasibility Study.  Ausenco personnel who will be involved in the feasibility have worked on other notable projects such as Andean’s Cerro Negro project in Argentina and Ivanhoe Mines’ Oyu Tolgoi project in Mongolia.

·                  SRK Consulting and Itasca Consulting Group Inc. have been retained to perform studies to determine pit slope stability that will help determine the project’s strip ratio and also the location of the proposed process facilities. Approximately half of the required work has been completed.

·                  An expanded infill drill program is underway at both El Gallo and Palmarito to upgrade inferred mineralization to the measured and indicated categories.

·                  Half of the proposed grinding tests for the mill and heap leach have been completed by SGS Mineral Services in Durango, Mexico.

·                  On-going bottle roll testing is being carried out on the different mineral zones in order to better quantify the expected mill recoveries. Two additional column tests are in progress to help determine heap leach recoveries. Column tests are completed or in progress on seven composites, and an additional three composite tests are planned.  SGS Mineral Services is also performing these tests.

·                  Feasibility is expected to be completed by year-end.

b)             Mine Permitting

·                  Heuristica Ambiental, environmental consultants of Sonora, Mexico has been engaged to complete the required environmental studies to mine and process ore at El Gallo. Heuristica Ambiental’s previous work included the successful permitting of Coeur d’Alene’s Palmarejo silver-gold mine in Chihuahua State, Mexico. Baseline environmental studies commenced last December.

·                  Permit application is expected to be completed in conjunction with the feasibility study.

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 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.
