US Gold’s Drilling in the Magistral District Returns 23.7 Opt Silver Over 5.9 Ft., Within 9.2 Opt Silver Over 31.0 Ft. ; Results Continue to Extend Main Zone

September 25, 2008

TORONTO, ONTARIO–(Marketwire – Sept. 25, 2008) – US GOLD CORPORATION (TSX:UXG)(AMEX:UXG)(FRANKFURT:US8) announces that drilling within the Magistral District, Sinaloa State, Mexico, continues to expand the mineralization and intersect richer silver grades at the Palmarito Project. Drilling has successfully extended the Main Zone by 310.0 feet (ft.) (95.0 meters) to the northeast and 105.0 ft. (32.0 meters) vertically. The furthest hole drilled to the northeast returned 23.7 ounces per ton (opt) silver over 5.9 ft., (814.0 gpt (grams per tonne) silver over 1.8 m), within an intercept of 9.2 opt silver over 31.0 ft. (313.8 gpt silver over 9.5 m). The zone remains open and shows good potential for expansion.

PALMARITO – MAIN ZONE

Richer Silver Mineralization at Depth

Core drilling continues to successfully extend the silver-gold mineralization down-dip of the Main Zone (Figure 1 & 2). RC results released earlier this year included 15.7 opt silver eq. over 30 ft. (538.6 gpt silver eq. over 9.1 m) and 13.6 opt silver eq. over 15 ft. (464.7 gpt silver eq. over 4.6 meters). US Gold’s exploration is discovering higher silver grades at depth, which suggests drilling may be nearing a possible feeder system. Recent results from the Main Zone include:

The results above successfully expanded the Main Zone by 310.0 ft. (95.0 meters) to the northeast. The vertical extent of the mineralization was expanded by 105.0 ft. (32.0 meters) to a total of 863.0 ft (263.0 meters) below surface. The furthest hole drilled to the northeast returned our highest assay values to date, 23.7 opt silver over 5.9 ft., (814.0 gpt silver over 1.8 m), within 9.2 opt silver over 31.0 ft. (313.8 gpt silver over 9.5 m). Two additional holes, stepping out 325.0 ft (100.0 meters) further to the northeast, are in progress and are targeting the possible feeder system. The zone remains open and shows good potential for expansion.

“The higher-grades at Palmarito are great to see! Although additional drilling is required, we believe the potential to discover more high-grade is excellent. Overall, our exploration in Mexico is starting to hit its stride and I look forward to watching it unfold,” stated Rob McEwen, Chairman and CEO of US Gold.
