EXPLORATION NEWS RELEASE

EL GALLO CONTINUES TO GROW RAPIDLY

MORE THICK INTERCEPTS & GOOD GRADE

125.6 GPT OVER 81.4 METERS, 273.8 GPT SILVER OVER 23.1 METERS

& 725.1 GPT SILVER OVER 8.1 METERS

TORONTO, ONTARIO (April 6, 2010) US GOLD CORPORATION (NYSE Amex: UXG) (TSX: UXG) is pleased to announce additional core drilling results that have expanded the mineralization (Fig. 1) at the El Gallo Project in Sinaloa State, Mexico. The three best holes of the eight assayed since the last update on March 24, 2010 are: 3.7 ounces of silver per ton (opt) over 266.9 ft (feet) (125.6 grams per tonne silver over 81.4 meters (m), 8.0 opt silver over 75.6 ft (273.8 gpt silver over 23.1 m) and 21.1 opt silver over 26.6 ft (725.1 gpt silver over 8.1 m).

Main Zone — Thick Intersections of Good Grade Continue

Mineralization Open in Several Directions

Drilling in the Main Zone successfully extended the mineralization in several directions (Fig. 1, 3). Core hole GAX100, which intersected three thick zones, successfully extended the mineralization encountered in GAX055 (11.4 opt silver over 368.8 ft (390.3 gpt over 117.9 m - Released Feb 11, 2010) by approximately 130 ft (40 m) to the north (Fig. 3).

Core hole GAX122 was drilled to extend the mineralization beyond hole GAX057 (8.3 opt silver over 128.8 ft (283.4 gpt over 39.3 m - Released March 1, 2010), which is the furthest hole drilled along strike to the southeast. This hole was drilled from the same collar location as GAX057 and successfully widened the zone by approximately 80 ft (25 m). US Gold’s geologists believe the potential to find additional mineralization is excellent since the zone remains open in several directions.  Highlights from this drilling are shown below.

Possible Parallel Zone: High Grades Encountered at Surface and at Depth

Hole GAX103 encountered two intersections of mineralization (Fig. 4). The first intersection, starting at approximately 280 ft (85 m) below surface, is believed to be the continuation of the Main Zone at depth. The second intersection, starting from surface, appears to be a separate mineralized structure that parallels the Main Zone. Ongoing drilling will look to expand the mineralization in both areas. Highlights from drilling in this area are shown below.

Geological Technical Description of El Gallo

El Gallo is a low-sulfidation, epithermal silver deposit located within the Pie de la Sierra physiographic province of the Sierra Madre Occidental Range which is part of a Cretaceous to Tertiary magmatic arc with volcanic and associated sedimentary rocks that extends for hundreds of miles through northwestern Mexico. Cretaceous-Tertiary volcanic and volcaniclastic rocks rest upon a basement of Paleozoic and Mesozoic sedimentary and metamorphic rocks.  Intrusives of Late Cretaceous and Tertiary age cut these rocks locally.  Regionally, these intrusives are dominated by the granitic Sinaloa Batholith. El Gallo project is located near the margin of the Sinaloa Batholith.  Other shallow-level porphyritic intrusives also occur within the project area.  Silver mineralization is hosted in breccia and stockwork zones that occur primarily in the andesitic volcanic and intrusive rocks and to a lesser extent in quartz monzonite porphyry intrusive rocks. The shape of the mineralization has not yet been fully defined.

QUALIFIED PERSON

This news release has been viewed and approved by John Read, 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 1500 ppm silver or 10 ppm gold were re-analyzed using gravimetric fire assay. Standards and blanks were inserted every 20 samples.

All angle 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.
