![U.S. Silver Announces Results of Ongoing Diamond Drill Activities at the Galena Mine and Expanded Geological Team](https://www.goldseiten.de/media/goldseiten-news.jpg)
Highlights
- Results on the previously recognized Caladay lead zone have confirmed the existence of a broad mineable resource that appears to support lower cost bulk mining methods.
- Efforts to extend the Silver Vein at depth have produced some very high grade intercepts including 1,434 Ag opt over 1.6 feet and 112.1 Ag opt over 2.8 feet (see below) and evidence of additional mineralization beyond current mining levels. The Silver Vein has been a prolific producer for decades and the down dip extension of this mineralization is a key target as deposits elsewhere in the Silver Valley have demonstrated very high grade at depth.
- Dan Hussey has returned to Company as Chief Geologist bringing decades of experience in the Silver Valley and extensive experience at the Galena.
Drill Program To Date
Caladay Lead Zone: a large part of the 2012 Exploration program is focused on defining the extent of the Caladay Lead Zone between the 4,000 and 4,900 levels of the Galena Mine. Drill results from the 4,000 level confirms that the Caladay Lead Zone occurs as a broad mineralized zone up to 160 feet wide averaging 2.75 ounces per tonne (opt) Ag, and 3.52% Pb, with high grade sub-zones 7 to 20 feet wide containing 27.2 to113.2 opt Ag; and 6.8 to 18.36% Pb (See Below). The exploration drilling also targets the down dip projection of the Caladay Lead Zone from the 4,900 level to the 5,500 level. Current drilling at the 5,200 level had a 10.4 foot intercept showing 62.36 opt Ag indicating a wide low grade silver-lead zone extends from the 4,900 level to the 5,200 level.
Silver Vein Down Dip Extension: exploration drilling continues on the Silver Vein Down Dip Extension between the 4,900 and 5,500 Levels of the Galena Mine. Highlights of recently received results include the interception of 1,434 opt Ag and 15.9% Cu over 1.6 feet and 36.3 opt over 3.2 feet in drill holes 52-352 and 52-354 respectively.
Gordon Pridham, CEO and Executive Chairman of U.S. Silver said, “Our expanded exploration program is proving to be very encouraging on several fronts and we believe that these efforts will continue to expand our silver assets in the historically prolific Silver Valley in northern Idaho.” Mr. Pridham, continued, “The results, so far in 2012, have confirmed and expanded expected mineralization that will lead to development plans and also identified new areas of mineralization for further investigation. We are also pleased to announce the addition of two new senior geological staff to manage the program. Dan Hussey has returned to Company as Chief Geologist and brings decades of experience in the Silver Valley and extensive experience at the Galena. Dave Cockrum, a professional geologist has joined U.S. Silver as Exploration Manager and is responsible for identifying and pursuing new exploration concepts and targets. He brings 27 years of extensive and varied geological experience and some fresh approaches to our assets.”

2012 Drilling Program Priorities
The results so far in 2012 have defined the direction of the exploration program that we will be pursuing both underground and on surface through the summer drilling months. Specifically the top four priorities are as follows;
1. Coeur Mine 3,700 Level - Drilling is scheduled for July at the Coeur Mine to test the down dip potential of known veins in the upper parts of the mine.
2. Caladay Lead Zone - Drilling at the 4,900, 5,200, 5,500 Levels of the Galena Mine will further refine the extent of the Caladay Lead Zone down dip and along strike. Drilling will continue through mid October to define the potential extent of a large bulk mineable deposit.
3. Surface Exploration Drilling – Drilling at the Coeur d’Alene Mine will begin in mid June to test the strike extension of known vein systems.
4. Silver Vein - Drilling to test the up-dip and down dip extensions of the Silver Vein at the Galena Mine will continue throughout the year. Drilling will be completed on the 2,400, 3,700, 4,000, and 5,500 levels.
