Additional High Grade Massive Sulphide Mineralization Identified at Silver Bull's Sierra Mojada Project

Silver Bull Resources, Inc. ("Silver Bull") is pleased to announce it has identified additional high grade massive sulphide mineralization at its Sierra Mojada Project in Coahuila, Northern Mexico.

Highlights from the new sulphide mineralization include;

  • Three channel samples grading: Sample 26708 @ 268g/t silver, 19% lead, 19.65% zinc, Sample 26709 @ 690g/t silver, 1% copper, 4.8% lead, 15.25% zinc, and sample 26710 @ 505g/t silver, 3.17% lead, 35.2% zinc.
  • The new sulphide mineralization lies within a 1.4 kilometer long east-west trending "chargeability high" identified through a gradient "Induced Polarization" (IP) survey. This east-west trend also hosts Silver Bull's only significant sulphide drill hole intercept of 8.45m @ 57g/t silver, 5.45% lead, 16.98% Zinc.
  • The chargeability anomaly remains open towards the east and west.
  • The new massive sulphide mineralization is accessible via existing historical underground workings.

The new sulphide mineralization lies within a 1.4 kilometer long east-west trending chargeability anomaly identified in a "Gradient Array IP survey" completed by Zonge Engineering and Research Organization, Inc. in 2010. The chargeability highs are interpreted as representing "pods" of sulphide mineralization at depth and in places correspond to areas that have historically been mined for copper, lead, and zinc massive sulphide mineralization up to 10 meters thick. In addition, drill hole B11144 sits 1.2 kilometers to the west of the new sulphide mineralization and along the same east-west chargeability trend and is the only drill hole to date to intersect any significant sulphide mineralization at Sierra Mojada, recording 8.45 meters @ 57g/t silver, 5.45% lead, and 16.98% zinc. The east-west chargeability trend remains open in both the east and west directions.

Tim Barry, President, CEO and director of Silver Bull states, "It is very significant to find another massive sulphide zone within the east-west chargeability trend and suggests the chargeability highs may indeed correspond to sulphide mineralization. The correlation of geology, geophysics, and geochemistry is strong and we believe the potential for sulphide mineralization at depth to the north is high and we are presently working to identify additional drill targets in this area."

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 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 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.
