US Gold Intersects Impressive High-Grade

El Gallo: 2.0 opt Gold, 5.3 opt Silver over 5 ft;

9.4 opt Silver over 50 ft, Inc. 28.0 opt Silver over 5 ft

Palmarito: 10.6 opt Silver over 75 ft, Inc. 33.0 opt Silver over 5 ft

Toronto, Ontario (December 17, 2008) - US GOLD CORPORATION (NYSE.A: UXG - TSX: UXG - Frankfurt: US8) announces a successful conclusion to its first year in Mexico and a bright outlook for 2009! Drilling from two projects within the Magistral District, located in Sinaloa State continues to intersect exciting high-grade results (Figure 1).

DRILL RESULT HIGHLIGHTS

·El Gallo – Results show excellent potential: 2.0 ounces per ton (opt) gold, 5.3 opt silver over 5 feet (ft) [70.1 grams per tonne (gpt) gold, 180.0 gpt silver over 1.5 meters (m)], within 15.0 ft  of 0.76 opt gold, 3.3 opt silver  [25.9 gpt gold, 112.1 gpt silver over 4.6 m].

·El Gallo – Strike length of initial discovery area extended to 425.0 ft (130.0 m): 10.4 opt silver over 45.0 ft [355.8 gpt silver over 13.7 m], including 27.3 opt silver over 5.0 ft [937.0 gpt silver over 1.5 m].

·Palmarito – Southwest Zone expands as grades get richer: 10.6 opt silver over 75.0 ft [363.3 gpt silver over 22.9 m], including 33.0 opt silver over 5 ft [1130.0 gpt silver over 1.5 m].

EL GALLO

High-Grade, Close to Surface and Near Mining Infrastructure

El Gallo is a recent discovery located 3mi (4.8km) north of the Magistral Mine (Figure 1).  US Gold believes the project has excellent potential based on the early results and strong alteration that has been found over a broad area. Results issued on November 26^th, 2008 returned significant mineralization: 43.6 opt silver and 0.45 opt gold over 55.0 ft [1494.7 gpt silver, 15.3 gpt gold over 16.8 m], including 104.1 opt silver and 1.0 opt over 20.0 ft. [3570.0 gpt silver, 34.6 gpt gold over 6.1 m].

Subsequent exploration was designed to 1) define and delineate the high-grade mineralization 2) connect the two initial discovery areas and 3) expand the known mineralization.

Delineation Drilling Confirms High-Grade Potential

Exploration was designed to establish the orientation of the high grade silver-gold mineralization located in the east portion of the project, in order to guide future drilling (Figure 2). Early interpretations suggest that the favorable mineral horizon is trending to the north. Recent assays have returned additional high-grade showing consistent thickness. Highlights are below:

Size Potential Opens Up – Discovery Areas Connect

Drilling between the two areas where silver mineralization was first discovered at El Gallo has returned the highest grades to date from this section of the project. These two areas were separated by 250.0 ft (75.0 m). Results are stated below:

This zone, combined with new results to the north, which returned 9.4 opt silver over 15.0 ft [322.0 gpt silver over 4.6 m], including 18.9 opt silver over 5 ft [648.0 gpt silver over 1.5 m] and 7.8 opt silver over 20.0 ft [267.5 gpt silver over 6.1 m], has now been identified over a total strike length of 425.0 ft (130.0 m) (Figure 2). Mineralization remains open to the north, east and west.

PALMARITO – Grades Keep Getting Better!

33.0 opt Silver (1130.0 gpt silver) over 5.0 ft (1.5 m)

The new Southwest Zone continues to expand and return high-grade mineralization (Figure 3).  The width of the mineralized zone has been extended by an additional 135.0 ft (41.0 m) and now totals 360.0 ft (110.0 m) wide, with recent results returning increasingly higher-grades, such as hole PMBHA08-076, which returned 10.6 opt silver over 75.0 ft (363.3 gpt silver over 22.9 m), including 33.0 opt silver over 5 ft. (1130 gpt silver over 1.5 m). This is the highest grade intercept drilled at Palmarito since US Gold began exploring the project. Highlights are listed below:
