U.S. Silver On-Going Exploration Drilling Identifies New High-Grade Zones

19.10.2010  |  Business Wire


U.S. Silver Corporation (TSX:USA, OTCQX:USSIF, Frankfurt:QE2) 'U.S.
Silver? or 'the Company? is pleased to announce positive results from
underground diamond drilling at the Galena mine near Wallace, Idaho.


U.S. Silver′s on-going underground exploration program continues to
identify significant new mineralized structures by following up on
historic diamond drilling and investigating the many under-explored
areas of the mine. During the third quarter, 13,524 feet (4,122 m) in 33
drill holes were completed. Three new veins and one down-dip extension
have recently been defined by drilling and/or drifting.


Tom Parker, President and CEO of U.S. Silver stated, 'We continue to
enjoy success with our underground drilling program at Galena. Our
ongoing ability to cost effectively add reserves well in excess of our
production over the past 4 years appears to be on track for 2010. Total
feet drilled is expected to be over 3 times the 2009 level. There
remains substantial silver to be found on our properties and we are
pursuing that goal at an increasingly aggressive rate.?

DRILLING HIGHLIGHTS

Galena Mine, 306 Vein, 4900-5200 Levels


Favorable drill results identified the deeper extension of the 306 Vein
from the 4900 Level to the 5200 Level. Galena crews initiated the
5200-288 cross cut south to intercept the vein. The crew has completed
475 feet (153 m) of track drifting and has crosscut the 306 vein. True
width rib assays on the 306 Vein are as follows:


  

  

  

  

  

  

  

  

  

306 Vein, West Rib

1.3 ft (0.40m) wide

106.8 opt Ag (3662 gpt) 1.32% Cu

306 Vein, East Rib

1.1 ft (0.34m) wide

38.3 opt Ag (1313 gpt) 6.03% Cu

  


Initial drifting along strike of the exposed vein is in progress. To
date, the vein has been exposed for 68 feet (21 m) with an average grade
of 21.55 opt Ag (739 gpt) and 0.83 % Cu, over an average true with of
4.1 feet (1.25 m).

Galena Mine, Polaris Fault Zone, 4000 Level


A new silver-copper (Ag - Cu) vein structure, having approximately 350
feet (107 meters) of strike length is being defined on the 4000 Level.
The vein has been identified in six of seven recently completed diamond
drill holes. The vein is situated west of the No. 3 Shaft Station in the
immediate footwall of the Polaris Fault, and is potentially related to
an existing resource of 10,200 tons grading 25.34 ounces per ton (opt)
Ag (869 grams per tonne), and 0.94% Cu, over an average width of 5.3
feet (1.62 m). Results of the six holes are as follows (vein widths are
corrected for true thickness):


  

  

  

  

  

  

  


DDH 40-199


from 378.3 ft:

3.0 ft (0.91m)

10.29 opt Ag (353 gpt) 0.41% Cu

DDH 40-200

from 277.5 ft:

4.1 ft (1.25m)


18.89 opt Ag (647 gpt) 1.10% Cu


  and


from 307.5 ft:

5.5 ft (1.68m)

9.66 opt Ag (331 gpt) 0.54% Cu

DDH 40-201

from 239.0 ft:

3.9 ft (1.19m)

9.61 opt Ag (329 gpt) 0.22% Cu

DDH 40-202

from 263.5 ft:

4.1 ft (1.25m)

8.14 opt Ag (279 gpt) 0.17% Cu

DDH 40-203

from 306.5 ft:

5.6 ft (1.71m)

2.57 opt Ag (88 gpt) 0.09% Cu

DDH 40-205

from 375.2 ft:


1.3 ft (0.40m)


22.60 opt Ag (775 gpt) 0.87% Cu

  


Track drifting to the new vein will be initiated in late October of this
year

Galena Mine, New Vein, 4300 Level


A new silver-copper vein structure currently having approximately 50
feet (15 m) of strike length has been identified on the 4300 Level,
within 50 feet of existing drift workings. The vein has been identified
in two of six completed diamond drill holes. The four holes with
negative results close the vein off to the east but it remains open to
the west. Results of the drilling are as follows (vein widths are
corrected for true thickness):


  

  

  

  

  

  

  

DDH 43-140

from 28.7 ft:

2.0 ft (0.61m)


18.36 opt Ag (629 gpt) 0.25% Cu


;  and,


from 50.8 ft:

1.0 ft (0.30m)

44.20 opt Ag (1515 gpt) 0.71% Cu

DDH 43-142

from 41.5 ft:

3.6 ft (1.10m)

33.90 opt Ag (1162 gpt) 0.62% Cu

  


Follow-up drilling to extend the strike length of the vein is planned
for December.

Galena Mine, 55 Vein, 5200 Level


A new silver-copper vein structure is being identified on 5200 Level.
The 55 Vein has been identified in three of five completed diamond drill
holes. The vein is situated east of the Galena Shaft station. Results
from the three holes are as follows (vein widths are corrected for true
thickness):


  

  

  

  

  

  

  

DDH 52-008

from 672.2 ft:

0.5 ft (0.15m)

223.0 opt Ag (7646 gpt) 2.10% Cu

DDH 52-269

from 724.9 ft:

3.7 ft (1.13m)

50.79 opt Ag (1741 gpt) 0.47% Cu

DDH 52-270

from 797.5 ft:

1.7 ft (0.52m)

8.43 opt Ag (209 gpt) 0.10% Cu

  


Design of a track drift to the new vein is currently being completed.


U.S. Silver continues to operate two contract diamond drills and one
in-house drill at the Galena mine. Plans are to continue this level of
drilling for the foreseeable future.
