US Gold Corporation: Mexico Exploration Update


DENVER, COLORADO--(Marketwire - July 7, 2008) - US GOLD CORPORATION (TSX:UXG)(AMEX:UXG)(FRANKFURT:US8) announces that recent drilling at the Magistral Mine, located in Sinaloa State, Mexico continues to encounter encouraging gold mineralization. Drilling designed to expand the mineralization around the Samaniego Pit returned 0.199 ounces per ton (opt) gold over 49.2 feet (ft.) (6.81 gpt (grams per tonne) gold over 15.0 meters), including 0.580 opt gold over 9.8 ft. (19.90 gpt gold over 3.0 meters). Also, drilling at the new Dos Amigos vein returning 0.397 opt gold over 19.7 ft. (13.63 gpt gold over 6.0 meters). Mineralization in both holes started at surface.

"Our positive exploration results from Magistral and the nearby Palmarito Project are clearly demonstrating the area's potential. Our objective in Mexico is to quickly grow the size of these projects in order to determine the optimum rate of production," stated Robert McEwen, Chairman and CEO of US Gold.


The exploration program at the Magistral Mine continues to successfully achieve its goals of expanding the mineralization and discovering new veins within the mine area.

Exploration continued to target the area around the Samaniego Pit. Since US Gold's last update, an additional 6,600 ft (2,000 meters) of drilling has been completed. Deeper conventional rotary holes have been focused on extending the mineralization at depth.

These deeper holes successfully extended the known mineralization with the best assay result being hole SWBH08-163 that returned 0.199 opt gold over 49.2 ft. (6.81 gpt gold over 15.0 meters). The deepest hole to encounter mineralization was SWBH08-161, which intersected 0.027 gold over 118.1 ft. (0.93 gpt gold over 36.0 meters). Mineralization in both holes started from surface.

Drilling appears to have intersected the upper portion of the main southwest-dipping vein that controls the gold mineralization inside of the Samaniego Pit. US Gold geologists believe there is good potential to intersect additional gold mineralization north and south of the current drilling (Figure 1). Highlighted results are listed below:

2. New Vein Intercepts 0.397 opt gold over 19.7 ft.

US Gold's team in Mexico continues to identify new veins with good potential. The Dos Amigos vein, which had never before been drill tested, has returned encouraging results (Figure 1). The best result from this area was 0.397 opt gold over 19.7 ft (13.63 got gold over 6.0 meters).

Dos Amigos is located approximately 1,500 ft (455 meters) northeast of Samaniego and is the second vein outside of the current resource estimate (Canadian National Instrument 43-101: Pincock, Allen & Holt 2006) that has returned good values since exploration began in January. The first vein, Cerritos, which was announced in May, returned 0.034 opt gold, 1.29 opt silver, 0.4% copper and 0.4% zinc over 39.4 ft. (1.16 gpt gold, 44.33 gpt silver, 0.4% copper and 0.4% zinc over 12.0 meters).

Exploration at Dos Amigos was performed using a conventional rotary drill with a limited depth capacity of 6 meters (19.7 ft) in order to quickly and cheaply test the near surface potential of the area (the drill was formerly used for production planning when Magistral was in operation). A total of 1,100 ft. (335 meters) of drilling has been completed. Ongoing exploration is now targeting the potential at depth and along strike. Highlights from Dos Amigos are listed below:

Production Planning Update

Engineering and resource studies have been initiated with the goal of optimizing the development of Magistral to achieve a production rate that is higher than previous owners had attempted (approximately 40,000 gold ounces per year). Metallurgical studies are currently being performed by SGS in Ontario, Canada and Durango, Mexico to assess alternatives to improve gold recoveries and determine possible extraction methods for silver.

Should resources expand sufficiently to justify a production rate greater than the current mine capacity, US Gold believes additions will have to be made to the current infrastructure, including fleet, process plant and crushing circuit.

An initial resource estimate at the Palmarito Project, located approximately 7.5 miles (12 km) southwest of Magistral, is scheduled to be completed by the end of the third quarter. This estimate could help support an increase to Magistral's future production.

Factors that could cause actual results to differ materially include, among others, those set forth in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2007 and other filings with the Securities and Exchange Commission, under the caption "Risk Factors".

Cautionary Note to U.S. Investors - All mineral resources have been estimated in accordance with the definition standards on mineral resources and mineral reserves of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in National Instrument 43-101, commonly referred to as NI 43-101. U.S. reporting requirements for disclosure of mineral properties are governed by the United States Securities and Exchange Commission (SEC) Industry Guide 7. Canadian and Guide 7 standards are substantially different.

The SEC permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. We use certain terms in this news release, such as "reserves," "resources," "geologic resources," "proven," "probable," "measured," "indicated," and "inferred," that the SEC guidelines strictly prohibit us from including in our filings with the SEC. 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 mineral resources will be confirmed or converted into Guide 7 compliant "reserves". Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute Guide 7 complaint "reserves" by SEC standards as a in-place tonnage and grade without reference to unit measures.
