Silver Bull Resources, Inc. announced the drill results for the tenth batch of drill holes from the underground drill program twinning a series of "long holes" in a high grade silver zone situated at the eastern end of the Shallow Silver Zone on the Sierra Mojada Project in Coahuila, Northern Mexico. High grade silver highlights from the tenth batch of 15 drill holes include: Hole T12093: 18 meters @ 178.19g/t Ag (including 7.6m @ 291.26g/t Ag); Hole T12094: 5.10 meters @ 118.61g/t Ag (including 1m @ 477g/t Ag); Hole T12095: 3.30 meters @ 125.30g/t Ag, 6.97% Zn, 0.24% Cu and 2.53% Pb; Hole T12096: 13.75 meters @ 95.72g/t Ag (including 2m @ 321.7g/t Ag); Hole T12111: 4.05 meters @ 264.50g/t Ag (including 1m @ 33.4% Zn and 729g/t Ag). The underground drill program at Sierra Mojada utilized two underground "Termite" rigs to twin a historical long hole data set with diamond core along a high grade silver zone and a high grade zinc zone located at the eastern end of the current resource.

The purpose of the program is to increase confidence in the long hole data set which represents approximately 38,000 meters of drilling that was either severally restricted or discarded in Silver Bull's NI43-101 resource report on the Shallow Silver Zone dated July 5, 2012. The high grade silver zone is hosted along a series of east-west trending structures with a combined traceable strike of approximately 3 kilometers and remains open in all directions. The twinning drill program concluded in mid December 2012 and amounted to 6,500 meters of drilling which resulted in the twinning of approximately 17% of the historic data set of 38,000 meters.

The company is awaiting final results from assays sent to ALS Chemex in North Vancouver, Canada. Upon receipt of all data, Silver Bull will initiate a revised NI43-101 resource update on the Shallow Silver and Zinc Zones, scheduled for release in the first quarter of 2013. The "Shallow Silver Zone" is an oxide silver deposit (+/- zinc & lead), hosted along an east-west trending fracture-karst system set in a cretaceous limestone-dolomite sequence.

At a 20g/t cutoff grade the Shallow Silver Zone has a measured resource of 3.023 million tonnes at an average grade of 65 g/t for 6.343 million contained troy ounces of silver, an indicated resource of 38.560 million tonnes at an average grade of 50 g/t for 61.694 million contained troy ounces of silver, and an inferred resource of 6.491 million tonnes at an average grade of 45 g/t for 9.478 million contained troy ounces of silver. The mineralized body averages between 30m - 90m thick, up to 200m wide and remains open in all 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.

In addition to the silver resource, Sierra Mojada also contains a significant "zinc oxide exploration target" which sits directly below and adjacent to the Shallow Silver Zone at its eastern end. The "Red" and "White" zinc zones have been identified through historical data containing 3,733 channels and 1,045 long holes over a 1.5 km strike length, but has too few core drill holes to presently delineate a NI43-101 compliant mineral resource. The zinc mineralization is composed of hemimorphite and lesser smithsonite and forms a tabular body hosted mostly within the upper dolomite along the east-west trending Sierra Mojada fault.

It is located 600 meters from a functioning railway and has been periodically mined for zinc grading greater than 20% over the last 100 years.
