US Gold Corporation: Drilling Around El Gallo Continues to Build on the Open Pit Potential08:30 EDT Wednesday, June 29, 2011TORONTO, ONTARIO--(Marketwire - June 29, 2011) - US GOLD CORPORATION (NYSE:UXG)(TSX:UXG) is pleased to announce new drill results from Palmarito and Haciendita, located within hauling distance of the company's El Gallo discovery and planned process facilities, in Sinaloa State, Mexico (Fig. 1). The results highlight the potential to grow the project as it moves through the feasibility stage. Currently 15 drills are operating at and around El Gallo. Exploration Highlights Palmarito Mineralization has been extended approximately 300 meters (985 feet) south, 100 meters (325 feet) west and 45 meters (150 feet) vertically, with intersections of 124.4 gpt silver over 9.2 meters, 638.0 gpt silver over 2.9 meters and 93.5 gpt silver over 12.5 meters. All results start at or near surface. Delineation drilling, designed to upgrade inferred mineralization to the measured and indicated categories, continues to confirm wide, near surface intersections of good grade: 106.5 gpt silver, 0.7 gpt gold over 18.8 meters. Testing a historic hole returns better grades and thickness, indicating an opportunity to potentially add ounces in previously defined areas. HacienditaResults from this recent discovery have returned additional encouragement, with gold values being intersected over good thicknesses: 2.1 gpt gold over 28.9 meters and 1.2 gpt gold over 19.7 meters.Palmarito Expanded in Multiple Directions (Fig 1, 2 and 3)The primary objective of US Gold's exploration at Palmarito is to continue expanding the near surface resource by drilling beyond and below the proposed open pit design. The latest results demonstrate the deposit has been extended in multiple directions, including a significant 300 meter (985 feet) step-out to the south (PMX-108), a 100 meter (325 feet) step-out to the west (PMX-095) and an additional 45 meters (150 feet) vertically (PMX-089 and PMX-106). Although infill drilling will be required, the silver mineralization intersected in these holes appears to be the continuation of the known zones and could have important implications for growing the resource. Highlights from the expansion holes are shown below.

The results continue to successfully confirm the grade and thickness of this mineralization.

Based on the drilling method (reverse circulation), US Gold believes there is a possibility the silver grades were understated. Earlier this year, drilling to infill and offset these earlier holes consistently returned better grades, helping to confirm this theory. US Gold has now twinned several historic reverse circulation holes, with the results from the first hole having been received. The holes were selected for twinning because they generally fell just outside of the planned pit and upgrading the silver values could help make this mineralization economic. The first hole encountered silver grades approximately 50% higher than the original. In addition, the zone was wider than anticipated. Once results from the remaining holes have been received, US Gold will determine if more twinning is warranted. Results comparing the two holes are shown below.

Drilling to follow up on these results is underway. Haciendita Exploration Drill Results (Fig. 1)New drilling has extended the Haciendita discovery to the northeast. In addition, two new zones have been discovered northwest and northeast of the initial drilling. The new results continue to return near surface, gold and silver mineralization over good widths and build upon results released earlier this year. The Haciendita area is comprised of near surface zones that are shallow dipping. It is located 10 km (6 miles) north of El Gallo. Highlights from the recent drilling are shown below.

US Gold explores for gold and silver in the Americas and is advancing its El Gallo Project in Mexico and its Gold Bar Project in Nevada towards production. US Gold's shares are listed on the NYSE and the TSX under the symbol UXG, trading 1.9 million shares daily during the past twelve months. US Gold's shares are included in S&P/TSX and Russell indices and Van Eck's Junior Gold Miners ETF. Rob McEwen, Chairman and CEO, owns 20% of the shares of US Gold. On June 14, 2011 the Company announced that Mr. McEwen proposed to combine the Company with Minera Andes to create a high growth, low-cost, mid-tier silver producer focused on the Americas.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 to one half of the split drill core is 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 1500 ppm silver or 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 been determined.
