El Gallo Continues to Grow, Delivering More High-Grade Silver 27.0 opt Silver Over 15 ft & 17.3 opt Silver Over 50 ft Within 150 ft of Surface
US GOLD CORPORATION (TSX:UXG)(NYSE Alternext US:UXG)(FRANKFURT:US8) announces new high-grade results from its El Gallo project in Sinaloa State, Mexico. Best intersections return 27.0 opt silver (925.3 gpt silver) over 15.0 ft (4.6 m) including 38.2 opt silver (1310.0 gpt silver) over 5.0 ft (1.5 m) and 17.3 opt silver (593.8 gpt silver) over 50.0 ft (15.2 m) including 41.4 opt silver (1420.0 gpt silver) over 5.0 ft (1.5 m) with mineralization all within 150.0 ft (45.7 m) of surface.
"In November US Gold announced a new high-grade discovery just three miles north of the company's Magistral Mine property in Mexico.
Our drilling has since returned numerous intercepts of significant mineralization. I am extremely pleased by the progress we have made in such a short period of time. We are pushing hard to determine the ultimate size dimensions of this discovery," stated Rob McEwen, Chairman and CEO.
During the past three months US Gold has rapidly expanded its exploration at El Gallo. With one diamond and two conventional rotary drills, four prospecting crews and a broad geochemical survey all showing exciting mineralization over a 4,000 ft (1200 m) x 2,800 ft (850 m) area, US Gold believes the growth prospects are excellent. To date, there has been a good correlation between targets developed through soil and rock sampling and positive drill results.
El Gallo Exploration Overview
US Gold's exploration at El Gallo is focused on 1) expanding the high-grade mineralization, in conjunction with defining our deeper drilling targets, 2) establishing continuity between the known mineralized areas and, 3) discovering new mineralized areas.
1) Expanding the High-grade & Defining Deeper Targets
In order to expand the high-grade mineralization and help define deeper drill targets, conventional rotary was used along the north and east portions of the main vein. In addition to intersecting very favorable mineralization, the results have outlined several discrete mineralized zones (Figure 2 and 3). The first zone, consisting of high-angle mineralization, was encountered in previous drilling; but shallow-dipping mineralization to the northwest and southeast was discovered in the latest round of drilling.
These results are encouraging, as they indicate the large potential to increase the total number of ounces, should these additional zones prove to have vertical and lateral continuity. Drill highlights from the two newly indentified shallow-dipping veins are below:

2) Establishing Continuity - Connecting Zones (Figure 1)
Results released on January 6th indentified three mineralized areas along the principal vein structure. Subsequent conventional rotary drilling was designed to test for continuity between these mineralized areas. Our goal was achieved on the eastern portion of the vein, where drilling intersected favorable mineralization, linking two of the zones together. Highlights from this drilling include:

- Cut-off grade 2.9 opt silver (100 gpt silver)
Numbers may not balance due to rounding
Initial drilling on the western portion of the vein extended the mineralization with drill hole GABHA-08-152 intersecting 11.7 opt silver (399.8 gpt silver) over 20.0 ft (6.1 m). However, further drilling on the western part of the vein was unable to connect the zones (Figure 1). The results have modified our understanding of the western area, where two separate veins appear to be present, one trending north-east and a second trending north-south.
3) New North Area Discovered
Drilling also focused on a geochemical target defined by surface rock samples approximately 500 ft (150 m) north of US Gold's current drilling. Six holes were drilled, with five successfully intersecting the anticipated zone, and the deepest mineralized intercept starting just 75.0 ft (22.9 m) below surface.

The grade of the mineralization and length of the drill intercepts are similar to the initial discovery holes that led US Gold geologists to the high-grade at El Gallo.
Project Advancement
Our objective is to test for lateral and vertical extensions of the known mineralization, in addition to targeting new mineralized zones. This information will serve as the basis for an initial resource estimate.
In order to help evaluate the economic potential of the project, US Gold has refurbished the metallurgical lab at its Magistral Mine property. This will allow the Company to determine potential gold and silver recoveries for the project. Our objective is to identify the production potential at El Gallo as quickly as possible.
