Vancouver, British Columbia - Silver Bull Resources, Inc. (TSX: SVB, AMEX: SVBL) ("Silver Bull") is pleased to announce more drill results from the 2011 drill campaign on the "Shallow Silver Zone".
Highlights include;

• Results from 62 diamond core drill holes into the "Shallow Silver Zone", equating to 11,024 meters of the 36,800 meter drill campaign completed in 2011.
• 80% of the drill holes intersected zones of silver oxide mineralization >30g/t Ag, including; 144g/t Ag over 31 meters, 109.3g/t over 12.55 meters and 89.4g/t Ag over 36.25 meters.
• Significant zinc intercepts including; 19.9% Zn over 10.85 meters, 4.57% Zn over 15 meters and 3.14% Zn over 57.70 meters.

Silver Bull's 2011 drill program of 183 drill holes totals 36,800 meters and focused on the "Shallow Silver Zone" and the newly discovered "Centenario. The program was designed to infill zones of mineralization defined by previous drilling as well as continue expanding the resource in north, east, and westerly directions through step out drilling. The results have confirmed the continuity and tenor of the extensive silver and zinc mineralization seen at Sierra Mojada, and mineralization remains open in all directions. Silver Bull's drill program is ongoing with 3 rigs currently onsite. Please see www.silverbullresources.com for more information.

About the Mineralization: A thick "upper" dolomite unit is the favorable host rock for the silver oxide mineralization seen in the Shallow Silver Zone, especially when immediately adjacent to fault zones. The discovery of the new "Centenario Zone" at the end of 2011, which is hosted within a stratagraphically "lower" dolomite unit and averages +100 meter intercepts at >60g/t Ag underlies the upper dolomite which hosts the Shallow Silver Zone.

A significant body of zinc oxide mineralization lies underneath and adjacent to the silver mineralization, coincident with the eastern half of the Shallow Silver Zone. The zinc mineralization is composed largely of the minerals hemimorphite and lesser smithsonite and forms a tabular body hosted mostly within the upper dolomite along the east-west trending Sierra Mojada fault. Extensive historical drilling and underground sampling shows a high grade core of mineralization >10% zinc sitting within a lower grade halo >4% zinc.

Tim Barry, President, CEO and director of Silver Bull states, "We are extremely pleased with the continued positive results coming from the Shallow Silver Zone. This particular batch of drilling focuses mainly on the margins of the known ore body and confirms silver mineralization retains significant thickness at the edges and remains open in all directions. We are also highly encouraged by the thick high grade zinc intercepts we are also intercepting towards the eastern end of the Shallow Silver Zone and look forward to publishing a resource update on both the silver and zinc in the second quarter of 2012".

Figure 1. Location of the reported holes in relation to the shallow silver zone shown in purple defined in the NI43-101 Resource report completed by SRK in October 2011.

About the Shallow Silver Zone: urrently 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.

NI43-101 Resource Update: The third in a series of NI43-101 resource updates is anticipated to be prepared by SRK Consulting (Canada) Inc. "SRK" in Q2 of 2012. All available data up to February 28, 2012 will be given to SRK for inclusion in the report. Given the drilling results to date it is anticipated that SRK's next report will show a substantial increase in the silver resource at Sierra Mojada, as well as including a resource for the significant zinc mineralization seen on the project.

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.

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.
