New Silver Intercepts Found at Shoshone Silver Mining’s Bilbao Project
March 5, 2007 -- WALLACE, ID -- Shoshone Silver Mining (PINK SHEETS: SHSH) is pleased to announce new results from ongoing exploration activities on its Bilbao property in the Zacatecas mining district, Mexico.
Drill hole X-26, part of the current phase of drilling examining the lateral extent of previously found zinc, lead and silver mineralization, encountered a zone of significant silver mineralization. Silver mineralization averaging 33.0 ounces per ton occurs over a 19 foot section, containing a 3 foot section of 94.9 ounces per ton silver.

Two Silver Veins Encountered
The first intercept of 16.9 ounce per ton silver over a 3 foot distance occurs at the juncture of the La Blanca granodiorite and the limestone sequence at 1187 feet. The second intercept is contained within the granodiorite formation extending from 1253 feet to 1272 feet.
The silver mineralization occurs in association with steeply dipping quartz
veins accompanied by minor amounts of galena and sphalerite. The angle of
intersection between the veins and the vertical drill holes appears to be quite
acute, therefore it is likely that true diameter of the veins is much less
than the length of silver mineralization found in the core samples analyzed.
Prefeasibility Study in Progress
Mr. Al Summers, an independent consulting mining engineer and former Vice President of Operations for Hecla Mining, has been hired by Shoshone’s joint venture partner Minco, PLC to conduct a Prefeasibility Study of the Bilbao project. The study will incorporate results of an independent resource evaluation commissioned by Minco and data from ongoing metallurgical and mineralogical tests being conducted on sulfide mineralization samples from the Bilbao project. Minco published the results from the resource evaluation on January 15, 2007.
