U.S. Silver & Gold Intersects Wide Zones of Silver Mineralization in Lead Zone at Galena Complex
TORONTO, Nov. 28, 2012 /PRNewswire/ - U.S. Silver & Gold Inc. ("U.S. Silver & Gold" or the "Company") (TSX:USA; OTCQX:USGIF) is pleased to provide an update on its 2012 exploration results. The Company's assets are comprised of two 100% owned operating mines: the high grade silver Galena Mine Complex in Idaho and the high grade gold and silver Drumlummon Mine in Montana.
"We are very pleased with our exploration progress at both the Galena Complex and the Drumlummon Mine," stated Jim Atkinson, Vice President, Exploration for U.S. Silver & Gold. "Results for the last eight holes from the 4900 level of the Galena Mine Lead Zone are especially encouraging. These holes are close to existing infrastructure and can be easily accessed. They were focused in an area where little drilling existed and displayed wide zones of continuous, good grade silver and lead mineralization. We plan to include these drilling results in our year-end resource calculation, and are working toward further defining the Lead Zone while examining low cost bulk mining methods."
Galena Mine Complex
The Lead Zone
Ongoing exploration work continues to define a significant potential silver resource in what is known as the Lead Zone ("LZ") of the Galena Mine Complex. It has over 750 drill holes, many of which were created to test other veins, principally the Silver Vein. The LZ has a global target of between 60 and 70 million tons and a potential global resource of between 150 and 200 million ounces of silver1. Please see Figure 1 for illustration. The 2012 drilling program focused on the initial delineation of a resource on the 4000 and 4900 Levels.
The underground drilling program continues to expand the size of the LZ and confirm the presence of potentially mineable grades and widths of silver and lead mineralization. Table 1 (below) shows the results of the eight most recent holes drilled at the LZ. They confirm mineralization grade and thickness in the accessible area on the 4900 level. They also test an area in the center of the mineralization block where there had been little previous drilling, and focus on expanding the known extent of the LZ at this level and below.
Holes have generally been drilled at a favorable angle to the mineralization and intersect close to true thickness, although actual thickness has yet to be determined. Mineralization is accessible from the 4900 level and the Company anticipates that it will be included in the year-end resource calculation for the LZ.

|Note: Since these drill holes were completed from different drill stations and intersect the veins at various angles, the recovered intersections may not reflect true widths.|
The LZ is a semi-continuous mineralized zone that extends throughout the Galena Mine from the 2400 level to the 5200 level, and potentially into the Caladay Mine at depth. The estimated strike length on the known levels ranges between 1,200 and 3,600 feet and the apparent widths range between 200 and 400 feet. Highly mineralized portions can exceed 100 feet as shown in Table 1 above. The LZ occurs as a large lead-silver (Ag-Pb) zone of disseminated and stringer-controlled mineralization containing higher grade linear zones. It is anticipated that lower cost bulk mining methods will be used to exploit this potential resource.
The LZ appears to have potential global grades of 3 to 4 ounces per ton (103 to 137 grams per tonne) silver and 3 to 5 percent lead with higher grade occurring in zones within the LZ. All targeted areas contain 1 to 3 continuous zones of higher grade mineralization, ranging between 5.5 to 10.0 ounces per ton (189 to 343 grams per tonne) silver and 5 to 11 percent lead, surrounded by lower grade material. High grade zones represent 30 to 40 percent of the total global tonnage with continuous widths ranging between 15 and 30 feet.
1 Note that potential quantities and grades disclosed in this news release are conceptual in nature and there has been insufficient exploration to define a mineral resource on the all of the targets in the Galena Mine Complex. It is uncertain if further exploration will result in all of the targets in the Galena Mine Complex being delineated as a mineral resource.
The previously producing Belmont Mine in the Drumlummon area of Montana was purchased in the summer of 2012 by U.S. Silver & Gold. The mine produced approximately 500,000 tons in the early 1900s from the Bald Mountain and Belmont veins. In the late 1980s and early 1990s previous owners re-examined the property and Gulf Titanium completed a non 43-101 compliant resource estimate of 77,000 tons of 0.59 ounce per ton gold, and conducted test mining from a surface decline. A qualified person has not done sufficient work to classify the historical estimate as a current mineral resource. The Company is not treating the historical estimate as a current resource.
In the fourth quarter of 2012, the Company began a program to confirm previous drilling in the Belmont and Bald Mountain veins and discover new veins in the area. This drill program was established to "twin" previous intersections that had been discovered in the early 1990s. Early and deep snow resulted in cancellation of the drilling before the full program could be finished—however, two holes were completed and a third was started. The first hole (Bel 12-01) obtained seven intercepts with gold and silver mineralization as outlined in Table 2 below.

|Note the true thickness of the veins is not known but calculations based on the angle of the drill hole and the intersections suggest that they will be 80 to 90% of the intersected width.|
Belmont Drill Hole (DH) #1 was completed at an azimuth of 319 degrees and a dip of minus 40 degrees with a total depth of 1,094 feet. It was drilled from the top of Bald Mountain at an elevation of approximately 6,550 feet.
The second drill hole intersected a drift at the target depth in the Bald Mountain vein, but did encounter several veins in the upper parts of the hole with those assays still pending. The third hole was abandoned due to heavy snowfall and winter conditions which made it too hazardous to access to the drill site. The hole was capped and prepared for re-entry in the spring.
Quality Assurance / Quality Control ("QA/QC")
U.S. Silver & Gold maintains a QA/QC Program for all assays, whether completed at the Drumlummon laboratory or at a contract laboratory including the use of standards, blanks, duplicates. All QA/QC results are evaluated using a program of QA/QC monitoring. Both the contract laboratory and the Drumlummon laboratory maintain programs of QA/QC as well. Assays for the Belmont drilling were completed at the Company's laboratory at the Drumlummon Mine in Montana while the assays for the Lead Zone were prepared by a commercial laboratory located in Osburn, Idaho

Mr. Jim Atkinson, Vice President, Exploration and a Qualified Person under Canadian Securities Administrators guidelines has approved the contents of this news release.
Some of the potential quantities and grades disclosed in this news release are conceptual in nature. At the current stage of exploration, there is insufficient drilling to determine the extent of continuity of the mineralization required to define a mineral resource for all mineralization at the Galena Mine Complex and Drumlummon Mine. It is uncertain if further exploration will result in certain exploration targets being delineated as a mineral resource.
