US Gold Corp.: Exploration News Release

MAGISTRAL DISTRICT: MORE GROWTH, MORE GOLD, MORE SILVER

0.10 OPT GOLD OVER 60 FT.
5.6 OPT SILVER EQUIVALENT OVER 65 FT.
INCLUDING 13.6 OPT SILVER EQUILALENT OVER 15 FT.

Denver, Colorado (August 25, 2008) - US GOLD CORPORATION (AMEX:UXG - TSX: UXG - Frankfurt: US8) announces that drilling within the Magistral District, located in Sinaloa State, Mexico continues to expand the mineralization at the Magistral Mine and Palmarito Project.

MAGISTRAL DISTRICT EXPLORATION HIGHLIGHTS

• La Prieta Zone returned 0.10 ounces per ton (opt) gold over 60 feet (ft.), [3.26 gpt (grams per tonne) over 18.3 m] including 0.30 opt gold over 10 ft. (10.33 gpt gold over 3.0 m). Drilling this year has successfully expanded the zone 100 ft. (30 m) to the southwest.

• Deepest hole drilled at Palmarito intersected 5.6 opt silver equivalent (eq.)* over 65 feet (ft.) (191.4 gpt silver eq. over 19.8 meters), including 13.6 opt silver eq. over 15 ft. (464.7 gpt silver eq. over 4.6 meters). The vertical extent of the zone has been expanded a total of 344 ft. or 80% this year to 760 ft. (232 m) below surface.

• New Dos Amigos vein continued to deliver good results. Best result from recent drilling included 0.17 opt gold over 30 ft. (5.9 gpt gold over 9.1 meters), including 0.54 opt gold over 5 ft. (18.4 gpt gold over 1.5 meters).

“Our results are clearly demonstrating the area’s potential. It is great compliment to US Gold’s Nevada exploration. I am pleased the progress we have made in Mexico, where we have set an initial goal of increasing the total resource to 1.0 million ounces of gold from its current 541,000 ounces by spring 2009,” stated Rob McEwen, Chairman and CEO of US Gold.

MAGISTRAL DISTRICT

US Gold controls a large land position within the Magistral District, totaling over 530,000 acres. The two key areas where US Gold is exploring include the Magistral Mine and the Palmarito Project, which are located 7.5 miles (12 km) apart (Figure 1).

Please find the picture about Figure 1 under the following link: http://media3.marketwire.com/docs/uxg0825_fg1.pdf

Numerous areas exist within the district where historic mining occurred but little modern exploration has been conducted.

The key host rock for gold and silver mineralization within the area is andesite, which has been extensively mapped throughout US Gold’s property. With a large land position and favorable geology, US Gold likes the odds of making additional discoveries.

LA PRIETA ZONE
0.10 opt gold over 60 ft. – More Room to Grow

The La Prieta Zone (Figure 2) is located inside of the Magistral Mine.

Drilling this year has successfully extended the mineralization by 100 ft. (30 m) to the southwest. US Gold’s earlier drilling on this zone returned 0.093 opt gold over 101 ft. (3.17 gpt over 30.8 m), including 0.274 opt gold over 20 ft. (9.39 gpt gold over 6.1 m). Results from the most recent step out hole are below:

Two additional holes are currently being drilled with the goal of expanding the La Prieta Zone further to the southwest where it remains open.

In March, we intersected silver mineralization above the high grade gold La Prieta Zone. Follow up drilling has successfully encountered additional silver mineralization. Results are stated below:

PALMARITO PROJECT
Mineralization Still Expanding

Reverse circulation (RC) drilling continues to successfully extend the silver-gold mineralization down-dip of the Main Zone (Figure 3: Plan map) (Figure 4: Cross section as indicated on plan map).

Please find the picture about Figure 4 under the following link: http://media3.marketwire.com/docs/uxg0825_fg1.pdf

Results from the Main Zone released August 6th included 10.2 opt silver eq. over 70 ft (349.2 gpt silver eq. over 21.3 m), including 15.7 opt silver eq. over 30 ft. (538.6 gpt silver eq. over 9.1 m). Highlights from recent drilling are listed below:

Please find the results under the following link: http://www.irw-press.com/dokumente/UXG_table3.pdf

These results extended the Main Zone’s vertical depth by 105 ft. (32 m) or 16% to 760 ft. (232 m) below surface. Since exploration began in January US Gold’s drilling has increased the vertical extent of the Main Zone by over 344 ft. or 80%.

RC drill hole PMX-23, which returned 5.6 opt silver eq.* over 65 ft. (191.4 gpt silver eq. over 19.8 meters), including 13.6 opt silver eq. over 15 ft. (464.7 gpt silver eq. over 4.6 meters) is the deepest hole and furthest to the northeast thus far. To date, drilling within the zone has demonstrated good continuity and consistent grade, increasing our confidence that the zone extends further.

US Gold believes Palmarito is an important asset that will help the company reach its 1.0 million gold equivalent ounce goal inside the Magistral District.

DOS AMIGOS – MAGISTRAL MINE
Near Surface, Grades Up To 0.17 opt Gold Over 30 ft.

Conventional rotary drilling at the new Dos Amigos vein located at the Magistral Mine, was designed to delineate a zone of near surface gold mineralization, which could be followed up with RC drilling in order to be incorporated into Magistral’s resource estimate. This was successfully achieved. Highlights from the recent set of rotary holes are below:

SAN RAFAEL PIT
Exploration Continues to Find More Gold

The San Rafael Pit was the primary source of Magistral’s past gold production, with approximately 50,000 ounces produced from this area. US Gold has renewed exploration in this area with the goal of finding more gold around the previously mined area and at depth. Results announced on August 6th included 0.12 gold over 30.0 ft. (4.1 gpt gold over 9.1 m). Conventional rotary drilling northeast of the pit has intersected additional gold mineralization. Results from this hole are stated below:

Please find the results under the following link: http://www.irw-press.com/dokumente/UXG_table5.pdf


This news release contains results that continue to both confirm the validity of our exploration model and to suggest that the potential for finding additional gold and silver ounces is excellent.

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
