Silver Bull Intersects 51.8g/T Silver Over 109.4 Meters to Further Extend the New "Centenario" Discovery at the Sierra Mojada Project, Coahuila, Mexico.
VANCOUVER, British Columbia, Jan. 11, 2012 /PRNewswire/ -- Silver Bull Resources, Inc. (TSX: SVB, AMEX: SVBL) ("Silver Bull") is pleased to provide the results for another 8 drill holes that were completed at the end of 2011 targeting the "Centenario Zone", a new zone of silver mineralization that lies to the north and immediately adjacent to the "Shallow Silver Zone".
Highlights include;
• 4 drill holes with 100+ meter intercepts of silver oxide mineralization, and 2 drill holes with 85+ meter intercepts of silver oxide mineralization.
• The extension of the known mineralized zone by a further 200m in an east-west direction and 100m in a north-south direction, currently giving the "Centenario" Zone a 400m east-west strike and a 150m north-south strike.
• The new zone lies approximately 300m to the north of the Sierra Mojada Fault which hosts the main body of the "Shallow Silver Zone" that has a present NI 43-101 compliant resource of 47.3 Moz of silver in the "indicated" category and 13.8 Moz of Silver in the "inferred" category.

* Drillholes that were previously reported in Silver Bull's news release dated 1 November 2011
** Intervals shown are mineralized lengths of core and are not necessarily true widths.
The Centenario Zone is hosted along the "Centenario" fault, a buried east-west trending structure which lies 300m to the north of, and runs parallel to, the "Sierra Mojada" fault – which hosts the Shallow Silver Zone. The widest part of the mineralization in the Centenario Zone occurs at the intersection of the Centenario fault and a major north-south trending fault which cross cuts the entire deposit. Like the Shallow Silver Zone, a thick dolomite unit appears to be the favorable host rock for the mineralization, especially when immediately adjacent to fault zones. The dolomite unit which hosts this new mineralization sits below the dolomite unit which hosts the Shallow Silver Zone in the stratigraphic sequence at Sierra Mojada and provides a new and completely untested horizon for mineralization in the future.

Although the mineralization starts below 100m it is important to note that the Centenario Zone falls within the surface projection of a conceptual Whittle open pit outline provided by SRK Consulting (Canada) Inc. in their recent resource update of the Shallow Silver Zone. This means that by mining out the Shallow Silver Zone a significant portion of the overburden will be removed.
Tim Barry, President, CEO and director of Silver Bull states, "We are extremely pleased with the continued positive results coming from the Centenario Zone which highlights the potential of Sierra Mojada as a large low grade silver deposit similar in style to Coeur d'Alene Mines Corporation Rochester mine. Following on from the $10.5 million financing we completed in December 2011, we are well positioned to continue drilling out the Centenario Zone as well as the extension to the Shallow Silver Zone in the west. In addition to focusing on increasing the silver resource, our exploration program in 2012 will also focus on better defining the very significant zinc mineralization we also see at Sierra Mojada".
Sample Analysis and QA/QC
All samples have been analyzed at ALS Chemex in North Vancouver, BC, Canada. Samples are first tested with the "ME-ICP41m" procedure which analyzes for 35 elements using a near total aqua regia digestion. Samples with silver values above 100ppm are re-analyzed using the Ag-GRA21 procedure which is a fire assay with a gravimetric finish. Samples with zinc, lead, and copper values above 10,000ppm (1%) are re-analyzed using the AA46 procedure which is a near total aqua regia digestion with an atomic absorption finish.
A rigorous procedure is in place regarding sample collection, chain of custody and data entry. Certified standards and blanks, as well as duplicate samples are routinely inserted into all sample shipments to ensure integrity of the assay process. The QA/QC of the assay results has been contracted to IOGlobal, an international and independent QA/QC and database management firm.
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 and currently contains a NI43-101 compliant resource at a 15g/t cutoff grade of 47.3Moz of silver in the "indicated" category and 13.8Moz of silver in the "inferred" category. The mineralized body averages between 30m – 90m thick, is up to 200m wide and has an average grade of just over 50g/t silver. Mineralization remains open in the east, west, south and northerly directions. Approximately 60% of the current 3.2 kilometer mineralized body is at or near surface before dipping at around 10 degrees to the east.
About Silver Bull
Silver Bull is a well funded, 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 licences in Gabon, Africa, two of which are currently under joint venture with AngloGold Ashanti. These licences are prospective for gold, manganese, and iron ore.
