Vancouver, British Columbia -- Silver Bull Resources, Inc. (TSX: SVB, NYSE MKT: SVBL) ("Silver Bull") is pleased to provide the results that will be reported in the updated NI43-101 Technical Report ("the Technical Report") currently being completed by JDS Energy & Mining Inc. ("JDS") on the silver and zinc mineralization of the "Shallow Silver" and "Zinc" Zones at the Sierra Mojada Project in Coahuila, Mexico. Highlights at various cutoff grades for the silver include;

• An Indicated silver resource of 71.9 million tonnes at an average grade of 72.5g/t silver totaling 167.5 million troy ounces of silver at a 25g/t silver cutoff grade.
• An Indicated silver resource of 40.75 million tonnes at an average grade of 102.2g/t silver totaling 134.0 million troy ounces of silver at a 45g/t silver cutoff grade.
• An Indicated silver resource of 20 million tonnes at an average grade of 147.8g/t silver totaling 94.0 million troy ounces of silver at a 80g/t silver cutoff grade.
• An Indicated zinc resource of 2.19 billion pounds of zinc at an average grade of 1.38%.
• An Inferred lead resource of 538 million pounds at an average grade of 0.34%.
• An Inferred copper resource of 126 million pounds at an average grade of 0.08%.

A summary of the mineral resource estimate for silver and zinc at various silver cutoff grades is as follows:
 

Note: Recoveries of 100% were assumed for the pit optimization. 

In addition to silver and zinc in the "indicated" category, an "inferred" resource of lead and copper was also estimated based on the various silver cutoff grades. The lead and copper resource is as follows:
 

In order to establish a reasonable prospect of economic extraction in an open pit context, the reported silver resource falls within a Lerchs-Grossman Optimized pit shell that uses a silver price of US$29.20/oz, a zinc price of US$0.95 per pound, US$3.70 per pound copper, and US$1.00 per pound lead. Pit walls are set at 50 degrees overall, and mining costs were assumed to be US$1.50/tonne, G&A US$1.00/tonne and silver and zinc processing costs at US$12.00/tonne. Metal prices are based on the trailing 3 year averages for silver, zinc, copper, and lead.

Silver and zinc mineral resources were estimated by ordinary Kriging using 3-D Mintec MineSightTM V7 block modeling software in multiple passes using 20 meter X 10 meter X 5 meter blocks as the SMU size. The geologic wireframes were updated and a partial model technique utilized to calculate accurate volumes. Grade estimates were based on 1 meter composited assay data with search radius restricted to a 20 meter search radius when a zone dependent cap limit was reached. Blocks have been classified as indicated mineral resources.

At a 25 g/t cutoff grade for the silver, the updated resource represents a 103% increase in the open pittable resource of the Shallow Silver Zone previously reported by Silver Bull's July 2012 NI43-101 Technical Report. Additional data added in this report includes; 10,056 meters of surface diamond drilling, 6,647.5 meters of underground diamond drilling completed for the "twinning" program of the historical long hole data set and approximately 400 new channel samples. With the success of the twinning program in showing an exceptional correlation with the long hole data set, a significant increase in the range of influence of 40,240 meters of long hole data has also been included in the resource estimation. Recent highlight intercepts from the twinning program include;

• 912g/t Silver over 17.6 Meters including 1,927g/t Silver over 3.66 Meters
• 463.55g/t Silver over 15.05 Meters including 1654.92g/t over 3.1 Meters
• 202.7g/t Silver over 42.65 Meters including 878g/t over 3.9 Meters
• 193.38g/t Silver over 43.65 Meters including 440.66g/t over 15 Meters
• 158.9g/t Silver over 30.75 Meters including 2,250g/t over 1 Meter
• 151.6g/t Silver over 57.30 Meters including 600.6g/t over 5.95 Meters
• 19.52% Zinc over 22.85 Meters including 47.59% over 4.4 Meters
• 15.65% Zinc over 43.55 Meters including 20.26% over 14.5 Meters

In addition to the silver and the zinc, a resource of lead and copper has also been estimated using an Inverse Distance Squared (ID2) modeling method. Because the geological constraints and metallurgical recovery on the copper and lead are not as well understood as the silver and zinc, the lead and copper resources estimates have placed in the "inferred" category. 

The mineral resource has been estimated by Garth Kirkham P.Geo. of Kirkham Geosystems Ltd. and reviewed by Allan Reeves P.Geo. of JDS Energy & Mining Inc. Mr. Reeves is an Independent Qualified Person as defined by National Instrument 43-101 and will be responsible for the Technical Report. As a consultant he has spent about 250 days onsite over a 3 year period providing technical advice and direction to the Silver Bull team. Mr. Kirkham is an independent consultant hired by JDS to prepare the resource estimation at Sierra Mojada. He is a leader in the field of resource estimation and was recently awarded the Julian Boldy Memorial award in 2012 by the Canadian Institute of Mining, Metallurgy, and Petroleum (CIM) for his "exemplary efforts in resource modeling and estimation".

Tim Barry, President, CEO and director of Silver Bull states, "We are extremely pleased with this report and feel this is a big step forward for the company. At over 167 million ounces, Sierra Mojada is now one of the largest undeveloped silver resources in Mexico. With our recently completed financing for gross proceeds of $USD 9.2 million, the company is well financed to push the project to the next stage with a preliminary economic assessment, which will be led by JDS. It is also no small point to note that even though we have defined a much larger resource than previously reported, mineralization remains open on the deposit, and during 2013 we will have an underground drill program underway using our low cost termite drill rigs which will target a high grade silver zone defined by underground channel samples immediately adjacent to the deposit".

Silver Bull will post the Technical Report from which the above resource numbers were extracted, onto the SEDAR website (www.sedar.com) upon receipt of the completed Technical Report which is expected within the next 45 days.

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. The mineralized body averages between 30m -- 90m thick, up to 200m wide and remains open in the east and west 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.

About Silver Bull: Silver Bull is a mineral exploration company listed on both the NYSE MKT and TSX stock exchanges and based out of Vancouver, Canada. The flagship "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 two mineral exploration licences in Gabon, 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 "measured resources", "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.
