Vancouver, British Columbia -- Silver Bull Resources, Inc. (TSX: SVB, OTCQB: SVBL) ("Silver Bull") is pleased to announce the start of a 2,000 meter underground diamond drill program targeting the newly identified zone of high grade sulphide mineralization recently identified at its Sierra Mojada Project in Coahuila, Northern Mexico.
 

• The proposed drill program uses the company owned Termite drill rig to target sulphide mineralization from historical underground workings. 
• Highlights from select channel samples in the new sulphide zone include:
  • Sample 25736 @ 1130g/t silver, 22% zinc, 3.26% lead, 12.8% copper.
  • Sample 25727 @ 1315g/t silver, 0.05% zinc, 9.0% copper.
  • Sample 25735 @ 713g/t silver, 3.4% zinc, 0.14% lead, 1.1% copper.
  • Sample 25805 @ 491g/t silver, 24.7% zinc, 1.6% copper.
  • Sample 25739 @ 495g/t silver, 7.09% zinc, 2.68% lead, 1.06% copper.
  • Sample 25728 @ 392g/t silver, 0.4% zinc, 1.8% copper.
  • Sample 25732 @ 329g/t silver, 42% zinc, 3.2% lead, 1.65% copper.
  • Sample 25806 @ 277g/t silver, 19.65% zinc, 18.3% lead, 0.7% copper.
  • Sample 25803 @ 73g/t silver, 19.2% zinc, 4.8% lead, 0.3% copper.
  • Sample 25802 @ 42g/t silver, 10.5% zinc, 2.4% lead, 0.17% copper.
  • Sample 25801 @ 33g/t silver, 8.1% zinc, 3.4% lead, 0.1% copper.
  
  The proposed drill program will utilize the company owned Termite drill rig, which is capable of drilling up to 100 meters of HQ diamond core. The purpose of the program is to test grade, thickness, and continuity of the sulphide mineralization over an east-west strike of approximately 300 meters recently identified and accessed through the reconditioning of historical mine workings. Five drill stations are presently planned with more expected to be added as the drill program progresses.

  prepared drill sites shown in the image below.

  
  Tim Barry, President, CEO and director of Silver Bull states, "This program will aim to extend our known zone of sulphide mineralization. Spatially this zone sits below the oxide resource at Sierra Mojada and is interpreted to be an extension at depth. There is potential for this area to be a feeder zone which emplaced the flat lying "manto" ore body which forms the current resource defined at Sierra Mojada."
  
  About the Sierra Mojada deposit: Sierra Mojada is an open pittable oxide deposit, as disclosed in the NI43-101 "Technical Report on the Resources of the Sierra Mojada Project Coahuila, Mexico" dated June 8, 2015, with a NI43-101 compliant measured and indicated "global" resource of 58.7 million tonnes grading 3.6% zinc and 50g/t silver at a $13.50 NSR cutoff giving 4.670 billion pounds of zinc and 90.8 million ounces of silver. Included within the "global" resource is a measured and indicated "high grade zinc zone" within the Lerchs-Grossman (LG) Optimized Pit of 10.03 million tonnes with an average grade of 11% zinc at a 6% cutoff, giving 2.426 billion pounds of zinc, and a measured and indicated "high grade silver zone" of 19 million tonnes with an average grade of 102.5g/t silver at a 50g/t cutoff giving 62.6 million ounces of silver. Mineralization remains open in the east, west, and northerly directions. Approximately 60% of the current 3.2 kilometer mineralized body is at or near surface before dipping at around 6 degrees to the east.
  
  Sample Analysis and QA/QC: All samples from the channel sample results above and from the drill program are/will be analyzed at Bureau Veritas in Vancouver, BC, Canada. Samples will be first tested with the "MA300" procedure which analyzes for 36 elements using a 4 acid digestion. Samples with silver values above 100ppm are re-analyzed using the FA350 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 AR402 procedure which is a near total aqua regia digestion.
  
  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 sample shipments to ensure integrity of the assay process.
  
  About Silver Bull: Silver Bull is a mineral exploration company whose shares are listed on the Toronto Stock Exchange and trade on the OTCQB in the United States, and is based out of Vancouver, Canada. The "Sierra Mojada" project is located 150 kilometers north of the city of Torreon in Coahuila, Mexico, and is highly prospective for silver and zinc.

  Cautionary Note to U.S. Investors concerning estimates of Measured, 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 measured, indicated and inferred 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 measured and 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.

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.
