U.S. SILVER CORPORATION DRILLS 19.8 FEET GRADING 63.90 OPT SILVER, 3.41% COPPER ON THE 3400 LEVEL OF THE GALENA MINE
U.S. Silver Corp. has received results from recently completed diamond drilling on the 3400 level at its underground Galena mine near Wallace, Idaho. Sixteen diamond drill holes were completed in the part of the mine known as the West Argentine zone, targeting the 215 and 117 veins. The drill holes were intended to infill those portions of the veins that are classified as probable reserves or inferred resource, and to test for extensions of the veins along strike.
The most spectacular hole drilled (DDH 34-105) hit 19.8 feet of siderite-tetrahedrite mineralization grading 63.9 ounces per ton silver and 3.41 per cent Cu. Aside from the grade, the intercept is significant because it is located 170 feet west of any previous mining on the 117 vein. The intercept in hole 34-105 was approximately 106 feet above the 3400 level. At this time the true thickness of the intercept is undetermined, but a drift toward the intercept is in progress and expected to reach the target by the end of August.
Bruce Reid, chief executive officer of U.S. Silver, states, "We are beginning to see the benefits from our aggressive underground exploration program as we have begun development in three new areas of the mine." A silver-lead zone on the 3700 level was discovered earlier this year and development is currently under way. Work has begun in preparation of drifting on the 2400 level toward the silver-copper and silver-lead mineralization west of the No. 3 shaft that was discovered late in 2006. In addition, development in the silver-lead ore zone on the 3000 level has begun and hoisting of this silver-lead ore to the surface using the Coeur shaft will begin in early September.
The recently completed drilling on the 3400 level was successful in extending known mineralization on the 117 vein further to the west as well as verifying the presence of ore-grade mineralization above and below the level on the 117 and 215 veins in areas currently classified as probable reserves or inferred resource. Underground diamond drilling is continuing in other areas of the mine with two diamond drills, each working two shifts per day.
All silver assay results reported in this news release were analyzed using standard fire assay techniques by American Analytical Services located in Osburn, Idaho. Check assays are conducted by ALS-Chemex, located in Sparks, Nev. All samples are obtained and assays are reported under a formal quality assurance program. All diamond drill core holes were drilled with BQ-size tools.
Selected drill hole intercepts from the recently completed exploration drilling on the 3400 level of the Galena mine are listed in the table of drill results.
