Silver Bull Identifies a New Massive Sulpide Zone Grading up to 1315 g/t Silver, 12.8% Copper, 18.3% Lead and 42% Zinc at the Sierra Mojada Project, Coahuila, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug 23, 2017) - Silver Bull Resources, Inc. (SVB.TO)(SVBL) ("Silver Bull") is pleased to announce it has identified a new zone of high grade massive sulphide at its Sierra Mojada Project in Coahuila, Northern Mexico.

Highlights from select channel samples in the new sulphide zone include:

  • Highlights from the channel sampling program 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 new sulphide zone lies within a 1.4 kilometer long east-west trending "chargeability high" identified through a gradient Induced Polarization (IP) survey. This east-west trending zone hosts two other zones Silver Bull has identified with sulphide mineralization which grade up to 690g/t silver, 35% zinc, 19% lead and 1% copper as well and also includes 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 west and coincides with a convex "roll over" in the sole of a thrust fault identified through drilling and underground mapping.

  • The new zone of massive sulphide is accessible via existing historical underground workings.

The channel samples mentioned in this news release target sulphide mineralization which grades up into the overlying oxide mineralization of Shallow Silver zone already defined at Sierra Mojada. The new sulphide zone was identified by accessing and reconditioning underground workings not previously accessible to Silver Bull. Continuous 1 to 3 meter long chip samples were taken along the walls of the underground workings. The purpose of the program was to extend the mineralization of the known sulphide zone, and better understand the geology and controls on the mineralization, and confirm the overall grades of the sulphide grades historically mined at Sierra Mojada. Approximately 280 meters of "new" underground workings were opened up and 19 initial channel samples taken. Eight samples recorded values over 250g/t silver with a peak value of 1315g/t silver, ten samples recorded values over 7% zinc with a peak value of 42% zinc, and six samples recorded values over 3% lead with a peak value of 18.33% lead.
