VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug 15, 2013) - Silver Bull Resources, Inc. (SVB.TO)(NYSE MKT:SVBL) ("Silver Bull") is pleased to announce the results of underground channel samples targeting the north, east, and western extensions to the Shallow Silver Zone on the Sierra Mojada Project in Coahuila, Northern Mexico.
Channel sample highlights include:
- NORTH EXTENSION: 1620g/t Ag over 1 meter, 1530g/t Ag over 0.6 meters, 1520g/t Ag over 1 meter, 1055g/t Ag over 1.27 meters, 781 g/t Ag over 2 meters.
- EAST EXTENSION: 1035g/t Ag & 28.3% Zn over 1 meter, 527g/t Ag & 17.4% Pb over 1 meter, 801g/t Ag & 19.6% Pb over 1.3 meters, 433g/t Ag & 18.95% Pb over 1 meter.
- WEST EXTENSION: 566g/t Ag & 10.15% Zn over 1.5 meters, 391g/t Ag & 1.16% Cu over 1.5 meters, 327g/t Ag & 2.59% Zn over 1.5 meters, 307g/t Ag & 1% Cu over 1.5 meters.
- All channel samples were taken along the walls of historical underground workings and lie outside the present silver resource of 162.9 million ounces of indicated silver (25g/t cutoff) and show the continued extension of the high grade mineralization in the north, east and westerly directions.
The channel samples mentioned in this news release target the extension of the high grade mineralization previously defined within the Shallow Silver Zone. Continuous 1 to 2 meter long chip samples were taken along the walls of historical underground workings at the north, east and western extents of the Shallow Silver Zone. The purpose of the program was to extend the high grade mineralization of the Shallow Silver Zone, better understand the geology and controls on the mineralization, and confirm the overall grades of the silver and zinc historically mined.
Approximately 440 meters of underground workings were sampled along the eastern extension, 330 meters along the northern extension, and 160 meters along the western extension. Of the 527 channel samples taken, 82 samples recorded values over 100g/t silver with a peak value of 1620g/t silver, 142 samples recorded values over 3% zinc with a peak value of 45% zinc, and 53 samples recorded values over 25% lead with a peak value of 19.75% lead.
Tim Barry, President and CEO of Silver Bull states, "It is important to realize that all of these channel samples fall outside the present 162.9 million ounce silver resource and clearly show that there is significant upside still left to be developed at Sierra Mojada. In the current market conditions the focus of the company right now is to finish up our metallurgical program and put out a Preliminary Economic Assessment on the significant silver and zinc resource we have defined at Sierra Mojada to date. We expect to have this report to the market out towards the end of September."

About the Shallow Silver Zone: The "Shallow Silver Zone" is an oxide silver deposit (+/- zinc, lead & copper), hosted along an east-west trending fracture-karst system set in a cretaceous limestone-dolomite sequence. At a 25g/t cutoff grade the Shallow Silver Zone has an indicated resource of 72.9 million tonnes at an average grade of 69.5 g/t for 162.9 million contained troy ounces of silver. The mineralized body averages between 30m - 90m thick, up to 200m wide and remains open in all directions. Approximately 60% of the current 3.8 kilometer strike length is at or near surface before dipping at around 6 degrees to the east.
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.
About Silver Bull: Silver Bull is a US registered mineral exploration company listed on both the NYSE MKT 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 has 2 mineral licenses in Gabon, Central Africa, which are prospective for gold, manganese, and iron ore.

Cautionary Note to U.S. Investors concerning estimates of Indicated and Inferred Resources: This press release uses the terms "indicated resources" and "inferred resources" which are defined in, and required to be disclosed by, NI 43-101. We advise U.S. investors that these terms are not recognized by the United States Securities and Exchange Commission (the "SEC"). The estimation of indicated resources involves greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that indicated mineral resources will be converted into reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. U.S. investors are cautioned not to assume that estimates of inferred mineral resources exist, are economically minable, or will be upgraded into measured or indicated mineral resources. Under Canadian securities laws, estimates of inferred mineral resources may not form the basis of feasibility or other economic studies.
Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations, however the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures. Accordingly, the information contained in this press release may not be comparable to similar information made public by U.S. companies that are not subject NI 43-101.
Cautionary note regarding forward-looking statements: This news release contains forward-looking statements regarding future events and Silver Bull's future results that are subject to the safe harbors created under the U.S. Private Securities Litigation Reform Act of 1995, the Securities Act of 1933, as amended (the "Securities Act"), and the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and applicable Canadian securities laws.

These statements are based on current expectations, estimates, forecasts, and projections about Silver Bull's exploration projects, the industry in which Silver Bull operates and the beliefs and assumptions of Silver Bull's management. Words such as "expects," "anticipates," "targets," "goals," "projects," "intends," "plans," "believes," "seeks," "estimates," "continues," "may," variations of such words, and similar expressions and references to future periods, are intended to identify such forward-looking statements. Forward-looking statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond our control, including such factors as the results of exploration activities and whether the results continue to support continued exploration activities, unexpected variations in ore grade, types and metallurgy, volatility and level of commodity prices, the availability of sufficient future financing, and other matters discussed under the caption "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended October 31, 2012, as amended, and our other periodic and current reports filed with the SEC and available on www.sec.gov and with the Canadian securities commissions available on www.sedar.com.
