US Gold Corporation: Nevada Exploration Update

US Gold Corporation: Nevada Exploration Update

DENVER, COLORADO -- (MARKET WIRE) -- 10/04/07 -- US GOLD CORPORATION (TSX: UXG)(AMEX: UXG) announced today results from its recently expanded exploration portfolio in Nevada. At Tonkin, the best gold assay results were 0.147 opt (ounces per ton) over 55 ft. (feet) (5.030 gpt (grams per tonne) over 16.8 m (meters)) and 0.115 opt over 23.9 ft. (3.937 gpt over 7.3 m); and at our Limo Project 0.166 opt over 26 ft. (5.685 gpt over 7.9 m) and 0.052 opt over 184.5 ft. (1.781 gpt over 56.2 m).

"Since our last exploration release on June 12, 2007, assay results from 44 holes totaling 35,964 feet of drilling have been received. We haven't hit any home runs yet, but we are on base and it is early in the game. We have advanced our understanding of the geology and confirmed that we have encountered wide sections of the right rock types to host a Carlin style gold deposit. In addition, we are fortunate to have a large land holding in a prospective area and a healthy treasury to fund our objective of exploring aggressively for the next Cortez Hills discovery. I must emphasize that exploration is the research and development of the mining industry, and it is typically a frustratingly slow and expensive process with low odds of success. The results in this press release are positive and encouraging, but not thrilling," said Rob McEwen, Chairman and CEO.

NEVADA EXPLORATION

Earlier this year we successfully completed the takeover of three companies, which significantly expanded our land holdings in the prolific Cortez Trend and elsewhere in Nevada. This press release reports drill results from our original property that we refer to as Tonkin, as well as three new properties, Limo, Keystone and Gold Bar.

LIMO

Management believes that Limo has many geological similarities to Barrick Gold's Bald Mountain Mine, which has current gold reserves of 3.5 million ounces. Limo is a large property of 20,000 acres. It has historic production of 93,000 ounces, difficult drilling conditions, and a few higher-grade intersections. Recent drilling began with two objectives:

1. Core drilling in areas previously tested by reverse circulation (RC) holes, to investigate if we can duplicate an earlier result that yielded higher grade assays with core; and

2. Exploring for extensions of known mineralization (see Figure 1).

Early results demonstrate that we have begun to achieve both goals.

Objective 1: Core drilling for better grade

Three holes have tested our hypothesis that RC drilling may have understated the grade due to the very broken state of the rock. The core drilling results were positive and produced results that were 33%, 56% and 859% better than earlier nearby RC drill holes (see table below and Figure 1.) If future drilling continues to deliver similar results, previously explored areas on the property may contain much more gold than originally believed.

Objective 2: Extending area of known mineralization

Hole L-03 encountered 0.166 opt over 26 ft. (5.685 gpt over 7.9 m) to the north of previous drilling. Drilling is underway to test if this represents an extension of high-grade mineralization along a defined structure. Hole L-10 was drilled 200 ft. (61 m) southwest of a historic high-grade area and encountered 0.052 opt over 184.5 ft. (1.781 gpt over 56.2 m) including 0.126 opt over 21 ft. (4.315 gpt over 6.4 m). These results, when viewed with the historic gold intercepts, suggest that the known area of mineralization has the potential to grow.

A total of 13 holes have been drilled at Limo, with three not reaching the target depth due to difficult drilling conditions.

TONKIN

Drilling was completed in three areas on this property, referred to as the Southern Area, Middle Area, and Fye Canyon.

Southern Area

Drilling targeted two potential gold mineralized trends with the best hole (T-148) returning 0.147 opt over 55.0 ft. (5.030 gpt over 16.8 m) (see Figure 2). This hole was drilled on a northeast trending structure and was designed to extend to depth a historic RC hole located nearby. This result marginally extended the mineralization by 11 ft. (3.4 m), but more importantly it increased the grade at a similar depth from 0.047 opt (1.61 gpt) to 0.147 opt (5.03 gpt). The implications of this result are currently being analyzed. Highlights from the Southern Area are stated below:

Hole T-148        0.147 opt over 55.0 ft.   (5.030 gpt over 16.8 m)
 Including        0.638 opt over 5.5 ft.    (21.845 gpt over 1.7 m)

Hole T-146        0.115 opt over 23.9 ft.   (3.937 gpt over 7.3 m)
 Including        0.387 opt over 6.0 ft.    (11.768 gpt over 1.8 m)
                  0.037 opt over 67.0 ft.   (1.252 gpt over 20.4 m)
                  0.081 opt over 19.5 ft.   (2.776 gpt over 5.9 m)

The second target was an east-west trending structure that is situated between two resource areas. Hole T-141 intersected 0.084 opt gold over 34 ft. (2.889 gpt over 10.4 m) and successfully extended the mineralization 310 ft. (95 m) east of hole T-129, which was released earlier this year and encountered 0.149 opt over 54 ft., including 1.175 opt over 1.7 ft. (5.10 gpt over 16.5 m, including 40.19 gpt over 0.5 m).

Middle Area

Drilling in the Middle Area intersected 0.124 opt gold over 15 ft. (4.252 gpt over 4.6 m) and 0.059 opt over 46 ft. (2.018 gpt over 14 m) and was designed to test for further high-grade results as achieved earlier this year in hole T-44 of 0.730 opt over 5 ft. (25.0 gpt over 1.52 m). These recent results demonstrate that the mineralization continues to the northeast, though similar high grades were not achieved.

Fye Canyon

Fye Canyon is located in the northern portion of the Tonkin property (see Figure 2). While no significant gold values were found, six holes encountered Carlin-style pathfinder elements in the Lower Plate rocks and a thickening of this favorable gold bearing unit to the north in an area US Gold believes is prospective.

KEYSTONE

Drilling has encountered no significant gold values in eleven holes at Keystone, but we remain optimistic about the base metal potential. Earlier this year one hole assayed 2.34 opt (80 gpt) silver, 0.99% copper, 1.19% lead and 1.23 zinc over 54 ft. (16.5 m). Previous exploration identified a grab sample that returned 23.8 opt (800 gpt) silver, 10.3% copper, 28.1% lead and 25.2% zinc. A gravity survey has located an anomaly that appears to be the extension of the base metal mineralization. Drilling is currently in progress.

GOLD BAR

Gold Bar is a prospective area due to its historic production of approximately 600,000 ounces of gold between 1985 and 1997. US Gold has recently compiled historic results with new mapping, geochemical sampling and geophysics. The results for US Gold's first four holes did not produce any significant gold values. This land package is large and further drilling is warranted.
