Tuesday, July 06, 2010

US Gold Corporation: El Gallo Initial Resource Estimate08:31 EDT Tuesday, July 06, 2010TORONTO, ONTARIO--(Marketwire - July 6, 2010) - US GOLD CORPORATION (NYSE Amex:UXG) (TSX:UXG) is pleased to announce details of an initial resource estimate for its El Gallo Project (100% owned) in Sinaloa State, Mexico. The resource estimate was prepared by Pincock, Allen and Holt (PAH) of Denver, Colorado in accordance with Canadian National Instrument 43-101 standards (NI 43-101). The resource is based on 97,110 feet (29,600 m) of core drilling. RESOURCE ESTIMATE HIGHLIGHTS -- Measured + Indicated resource totals 25.1 million ounces silver and 21,165 ounces gold within 7.4 million tonnes of material with an average grade of 3.4 opt (106 gpt) silver and 0.003 opt (0.09 gpt) gold (Table 1). -- Inferred resource totals 12.2 million ounces silver and 9,346 ounces of gold within 4.5 million tonnes averaging 2.7 opt (84 gpt) silver and 0.002 opt (0.06 gpt) gold (Table 1). -- El Gallo and surrounding projects (Magistral and Palmarito) to be included in the Preliminary Economic Assessment now total (Table 4 & 5): -- Measured + Indicated silver: 33.6 million ounces -- Inferred silver: 15.5 million ounces -- Measured + Indicated gold: 540,115 ounces -- Inferred gold: 23,282 ounces -- 93% of the Measured + Indicated and 94% of the Inferred resource at El Gallo is located less than 325 feet (100 m) below surface. -- Mineralization at El Gallo remains open in several directions. Exciting exploration program ongoing (Fig 1). Updated resource due at year-end. "When US Gold's geologists discovered El Gallo they believed it had similar potential to Pan American's Alamo Dorado, one of the world's largest primary silver mines, located approximately 150 miles (240 km) north of our project. This initial resource demonstrates the projects are comparable in both size and grade. US Gold is currently carrying out an exciting exploration program that will look to further expand the resource and drill test a number of high priority regional targets. US Gold remains on schedule to deliver a Preliminary Economic Assessment by year-end, which will include an updated resource estimate," stated Rob McEwen, Chairman and CEO. El Gallo Resource Estimate The El Gallo resource estimate includes two cut-off grades since two different process methods are being considered. A 1.3 opt (40 gpt) silver cut-off was used for the sulphide/oxide mineralization using a mill recovery process (Table 2) and a 0.7 opt (25 gpt) silver cut-off for the near surface oxide mineralization using a heap leaching recovery process (Table 3). Lower grade sulphide mineralization less than 1.3 opt (40 gpt) that could potentially be heap leached has been excluded from the resource until additional column testing is completed. A conceptual open pit mining method was used for the purpose of delineating the mineralization with a reasonable prospect of economic extraction. Tonnage estimates were based on a 2.5 grams/cubic centimeter density factor. Ordinary kriging was used to interpolate silver grade and inverse distance was used to interpolate gold grade in the resource model (geostatistical methods of calculating resources). The database used to establish El Gallo's resource is based on 97,110 feet (29,600 m) of core drilling. El Gallo Next Steps 1. Drilling during the second half of 2010 will continue at a similar pace as the first six months, focusing on extending known mineralization and testing peripheral targets surrounding El Gallo (Fig 1) as well as evaluating other projects in the region within US Gold's property package. 2. A Preliminary Economic Assessment and updated resource estimate for El Gallo will be published by year-end. The study will contemplate shipping gold and silver ore from Magistral and Palmarito to an El Gallo process facility. Both Magistral and Palmarito have NI 43-101 compliant resource estimates (Table 4 & 5). Mr. Aaron McMahon, P.G., of PAH and Mr. John Read P.G., US Gold's consulting geologist, will be the authors of a NI 43-101 compliant Technical Report on the Mineral Resource Estimate for the El Gallo Project, to be filed within 45 days of this news release. Mr. McMahon is independent of US Gold as defined by NI 43-101. ABOUT US GOLD (www.usgold.com)US Gold is a Colorado incorporated company that explores for gold and silver.

CAUTIONARY STATEMENTS FOR U.S. INVESTORSThe resource estimates contained in this news release have been prepared in accordance with standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in Canadian National Instrument 43-101 (NI 43-101). These standards are different from the standards generally permitted in reports filed with the SEC. Under NI 43-101, US Gold reports measured, indicated and inferred resources, measurements which are generally not permitted in filings made with the SEC. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that any part of measured or indicated resources will ever be converted into economically mineable reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. Canadian regulations permit the disclosure of resources in terms of "contained ounces"; however, the SEC only permits issuers to report "mineralized material" in tonnage and grade without reference to contained ounces. Under U.S. regulations the tonnage and grade described herein under the "measured" and "indicated" categories would be characterized as mineralized material. The disclosure herein is being made by US Gold to provide a means of comparing its project to those of other companies in the mining industry, many of which are Canadian and report pursuant to NI 43-101, and to comply with applicable disclosure requirements.U.S. investors should be aware that the issuer has no "reserves" as defined by Guide 7 and are cautioned not to assume that any part or all of the potential target mineral resources will ever be confirmed or converted into Guide 7 compliant "reserves".Table 1Global El Gallo Resource Estimate ------------------------------------------------------------------------- METRIC Tonnage Silver Average Gold Average ------ ('000 tonnes) (oz) Silver Grade (oz) Gold Grade (g/tonne) (g/tonne) ------------------------------------------------------------------------- Measured 4,018 14,763,242 115 12,570 0.10 Indicated 3,375 10,337,234 95 8,594 0.08 ------------------------------------------------------------------------- Measured + 7,393 25,100,476 106 21,165 0.09 Indicated Inferred 4,490 12,167,489 84 9,346 0.06 ------------------------------------------------------------------------- Table 2 - Mill Process ScenarioEl Gallo Sulphide/Oxide Resource Estimate Cut-Off Grade 1.2 opt (40 gpt) ---------------------------------------------------------------------------- METRIC Silver ------ Cutoff Average Average Grade Tonnage Silver Silver Grade Gold Gold Grade (g/tonne) ('000 tonnes) (oz) (g/tonne) (oz) (g/tonne) ---------------------------------------------------------------------------- Measured 40 3,802 14,545,882 119.0 12,223 0.10 Indicated 40 3,106 10,065,676 100.8 7,989 0.08 ---------------------------------------------------------------------------- Measured + Indicated 40 6,908 24,611,558 110.8 20,212 0.09 Inferred 40 3,900 11,560,497 92.2 8,777 0.07 ---------------------------------------------------------------------------- Table 3 - Heap Leach Process Scenario El Gallo Oxide Resource Estimate Cut-Off Grade 0.7 opt (25 gpt) ------------------------------------------------------------------------- METRIC Average ------ Silver Cutoff Tonnage Silver Average Grade ('000 Silver Grade Gold Gold Grade (g/tonne) tonnes) (oz) (g/tonne) (oz) (g/tonne) ------------------------------------------------------------------------- Measured 25 216 217,360 31.3 347 .05 Indicated 25 269 271,558 31.4 605 .07 ------------------------------------------------------------------------- Measured + 25 485 488,918 31.4 953 0.06 Indicated Inferred 25 590 606,992 32.0 569 0.03 ------------------------------------------------------------------------- Table 4District Silver Resource Estimate ------------------------------------------------------------------ METRIC Tonnage Silver Average ------ ('000 tonnes) (oz) Silver Grade (g/tonne) ------------------------------------------------------------------ El Gallo Measured + Indicated 7,393 25,100,476 106 Inferred 4,490 12,167,489 84 Palmarito Measured + Indicated 3,757 8,472,048 70.1 Inferred 1,591 3,349,242 65.5 ------------------------------------------------------------------ Total Silver Measured + Indicated 33,572,524 Inferred 15,516,731 ------------------------------------------------------------------ (i)Magistral Resource Estimate - Pincock Allen & Holt (2009) (ii)Palmarito Resource Estimate - Pincock Allen & Holt (2008) Table 5District Gold Resource Estimate ------------------------------------------------------------------ METRIC Tonnage Gold Average ------ ('000 tonnes) (oz) Gold Grade (g/tonne) ------------------------------------------------------------------ El Gallo Measured + Indicated 7,393 21,165 .09 Inferred 4,490 9,346 .06 Palmarito Measured + Indicated 3,757 16,484 .14 Inferred 1,591 5,769 .11 Magistral Measured + Indicated 10,397 502,466 1.50 Inferred 223 8,167 1.14 ------------------------------------------------------------------ Total Gold Measured + Indicated 540,115 Inferred 23,282 ------------------------------------------------------------------ (i)Magistral Resource Estimate - Pincock Allen & Holt (2009) (ii)Palmarito Resource Estimate - Pincock Allen & Holt (2008) To view Figure 1, please visit the following link: http://media3.marketwire.com/docs/75uxgfig1.pdfFOR FURTHER INFORMATION PLEASE CONTACT: US Gold Corporation Ian J.
