US Gold Corp.: Mexico Exploration Update

RESULTS FROM THREE EXPLORATION TARGETS
0.093 OPT GOLD OVER 101 FT;
0.204 OPT GOLD, 30.08 OPT SILVER, 1.5% LEAD & 0.2% ZINC OVER 9.8 FT;
9.33 OPT SILVER OVER 44.9 FT

Denver, Colorado (March 25, 2008) - US GOLD CORPORATION (AMEX:UXG - TSX: UXG - Frankfurt: US8) is pleased to announce results from its Magistral Mine and surrounding regional projects in Sinaloa State, Mexico. Exploration from the Magistral Mine intersected 0.093 opt (ounces per ton) gold over 101 ft. (3.17 gpt (grams per tonne) gold over 30.8 meters). Projects outside the mine area continue to deliver interesting results. Highlights from the Shakira Project include 0.204 opt gold, 30.08 opt silver, 1.5% lead and 0.2% zinc over 9.8 ft. (7 gpt gold, 1030 gpt silver, 1.5% lead and 0.2% zinc over 3 meters). Drill results from the Palmarito Silver Project returned 9.33 opt silver over 44.9 ft. (319.6 gpt silver over 13.7 meters).

US Gold’s properties in Nevada remain buried in snow preventing cost effective access for drilling, however work continues on completing new resource estimates for Tonkin, Gold Bar and Limo, which are due to be published during the second and third quarters of 2008. US Gold’s Nevada exploration program will resume in late spring.

Meanwhile, exploration in Mexico continues to deliver promising results from around the Magistral Mine, the Palmarito project, and the Shakira project. Results in this release were received since our last exploration update on February 21st, 2008.

MAGISTRAL MINE UPDATE

Two projects are currently underway at Magistral, the first is designed to expand the known mineralized material of 541,000 ounces of gold (Based on Canadian National Instrument 43-101 Measured and Indicated Resource). Second is an evaluation of the economics of resuming production with a particular focus on capital costs and timing. The Magistral Mine produced approximately 70,000 ounces of gold between 2002-2005. The cash cost to produce an ounce of gold was approximately US$350 during the last full quarter of production, as reported by the previous owner. Magistral contains most of the essential equipment required to resume production including the process plant, rock crushers and mining fleet.

US Gold’s initial exploration program consists of approximately 32,500 ft. (9,900 meters) of drilling. To date assay results have been received for approximately 25% of the planned program.

Drilling at the Magistral Mine focused on two areas referred to as La Prieta and Lupita.

Expanding Mineralization

Initial drilling in the area known as La Prieta successfully extended the gold mineralization by 100 ft. (30.5 meters) to the southwest. These drill results are outside previous resource estimate limits and demonstrate that the mineralization remains open. Gold mineralization throughout the mine area commonly pinches and swells and can cause large fluctuations in grade and width within relatively short distances. The ongoing objective will be to track the vein in an attempt to build additional ounces at the mine. The best results from the step out drilling included:

Drill Hole Gold Length From To
(opt) (gpt) (ft.) (m) (ft.) (ft.)

MPX-009 0.031 1.07 55.0 16.8 435 490
Including 0.041 1.39 40.0 12.2 445 485

MPX-004 0.036 1.25 15.0 4.6 295 310


Drill Hole Silver Lead Zinc Length From To
(opt) (gpt) (%) (%) (ft.) (m) (ft.) (ft.)

MPX-009 7.68 263.0 2.0 1.5 5.0 1.5 80 85


(opt = ounces per ton, gpt = grams per tonne)

These results are believed to be extensions of the mineralized zone. Thinner sections of lower grade gold mineralization may connect the higher grade zones. Further drilling will look to extend these zones further.


Confirming Prior Results

Previous exploration at Magistral was conducted primarily using reverse circulation drilling. In order to confirm the nature of the mineralization and better understand the structure that carries the higher grade gold, a limited number of core holes have been drilled. Results from the first hole included:


Drill Hole Gold Length From To
(opt) (gpt) (ft.) (m) (ft.) (ft.)

MPX-012 0.093 3.17 101 30.8 347 448
Including 0.274 9.39 20 6.1 353 373
Including 0.723 24.75 6 1.8 369 373


This drill hole along with previous core holes has initially confirmed the grades and widths of the gold mineralization present at La Prieta. Four additional core holes have been completed in this zone with assays pending.


PALMARITO SILVER PROJECT

Palmarito is located approximately 7.5 miles (12 km) southwest of the Magistral Mine and is accessible by well maintained roads (See Figure 2). Palmarito was one of Sinaloa State’s most significant producers of silver with a total production of approximately 19 million silver equivalent ounces* when mining by third parties ceased in 1950.

New drill results received in 2007 were designed to follow-up on previous exploration and will form the basis of an initial resource estimate. Highlights from this program included:

Drill Hole Silver Length From To

Including 5.96 204.0 15.1 6.1 287.0 297.0



US Gold is currently completing a drill program (reverse circulation) of approximately 5,600 ft. (1,700 meters) and will initially target the down dip extension of the mineralization. The Company expects an initial resource estimate for Palmarito to be completed by the end of the third quarter 2008.

*Gold Price US$1,000 per ounce, Silver Price US$20


SHAKIRA PROJECT

Shakira is located approximately 12 miles (20 km) northwest of the Magistral Mine. Exploration has extended the zone to the north by an additional 150 ft. (45 meters). Since initial results were released in January, the mineralization has been traced over a total length of 350 ft. (106 meters) (See Figure 1). Percussion drilling has been used extensively at Sharika to guide exploration and has proven to be very useful tracking near-surface mineralization. Recent results are beginning to highlight the potential for lead and zinc, in addition to silver and gold. Highlights from our most recent exploration are detailed below:

Exploration encountered historical underground workings that caused holes S-77 and S-78 to be terminated prior to reaching their target depths. However, good mineralization was encountered throughout the upper portions of both holes and the results have helped to establish continuity and confidence in the mineralized zone.

US Gold has now completed an additional 6 holes (reverse circulation) in the Shakira area with the objective of extending the mineralization further to the north, south and at depth. Results from these holes are pending.

Exploration continued over the southeast Shakira area. The objective was to extend the mineralization announced in February from Trench #3. New results, including assays for base metals, indicate the mineralization has expanded and the area contains good zinc and lead values. Results for the two trenches include:
