About the Shallow Silver Zone; The "Shallow Silver Zone" is an oxide silver deposit (+/- zinc & lead), hosted along an east-west trending fracture-karst system set in a cretaceous limestone-dolomite sequence. The mineralized body averages between 30m – 90m thick, up to 200m wide and remains open in the east, west, south and northerly directions. Approximately 60% of the current 3.2 kilometer strike length is at or near surface before dipping at around 10 degrees to the east.

About the Silver Bull; Silver Bull is a US-registered mineral exploration company listed on both the NYSE Amex and TSX stock exchanges and based out of Vancouver, Canada. The flag ship "Sierra Mojada" project is located 150 kilometers north of the city of Torreon in Coahuila, Mexico and is highly prospective for silver and zinc. Silver Bull also owns three mineral exploration licenses in Gabon, Africa, two of which are currently under joint venture with AngloGold Ashanti. These licenses are prospective for gold, manganese, and iron ore.
