VANCOUVER, British Columbia, Oct. 9, 2012 /PRNewswire/ -- Silver Bull Resources, Inc. (TSX: SVB, NYSE MKT: SVBL) ("Silver Bull") is pleased to announce the drill results for the sixth 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.

Highlights from the sixth batch of 14 holes include:

• High grade silver intercepts including: 30.75 meters @ 158.98g/t Ag (including 1m @ 2,250g/t Ag, 1.2m @ 703.5g/t Ag & 5.35m @ 177.6g/t Ag), 14.55 meters @ 133.75g/t Ag (including 5.5m @ 330.4g/t Ag), 8.55 meters @ 133.88g/t Ag (including 1.4m @ 580.57g/t Ag) and 38.70 meters @ 81.34g/t Ag (including 7.8m @ 199.8g/t Ag & 1.4m @ 674g/t Ag).
• High grade zinc intercepts including: 24 meters @ 9.83% Zn, 2.6 meters @ 12.08% Zn, 2.55 meters @ 9.41% Zn and 1.4 meters @ 14.85% Zn.
• Mineralization remains open in the north, south, east and westerly directions.

Silver Bull's 3,000 meter drill program in the high grade silver zone is ongoing with 2 underground "Termite" rigs twinning a series of long holes with up to 50 meter long BQ sized diamond core drill holes. The high grade silver zone is hosted along a series of "stacked" east-west trending structures with a combined traceable strike of approximately 3 kilometers at the eastern end of the Shallow Silver Zone. The purpose of the program is to increase confidence in a historical long hole data set which defines the high grade silver zone and represents just under 38,000 meters of drilling which was either severally restricted or discarded in Silver Bull's latest NI43-101 resource report on the Shallow Silver Zone dated July 5, 2012.  As announced in the September 14, 2012 news release, Silver Bull will expand the underground drill program with an additional 2,000 meters of drilling to twin a series of long holes in the high grade zinc zone, which sits adjacent to and below the silver mineralization.  The twinning program in the zinc zone is scheduled to commence on the week of October 8, 2012.

In addition to confirming the grade and tenor of the silver and zinc mineralization with the twinning program, much of the historical long hole data set ended in significant mineralization, so the program will also look to extend the mineralization by drilling longer holes. Due to the limited range of the Termite drills, and despite extending some holes by as much as 25 meters, some holes still end in mineralization.

This recent drilling, coupled with historical channel sampling and our ongoing underground mapping program shows at least three distinct east-west trending structures which host high grade zones of silver mineralization. In places, these east-west trending structures are cross cut by a series of northeast trending faults resulting in a "blow out", which yields a much wider zone of high grade silver mineralization. A halo of silver mineralization grading up to 80g/t exists in between the high grade zones and provides the tonnage for a potential "bulk minable" deposit in an open pit setting. The high grade silver zone remains open in all directions and sits above and slightly adjacent to a significant body of zinc mineralization which has a present strike length of 1.5 kilometers and an average grade >8% Zn. 

A table of holes T12040 to T12054 from the underground long hole twinning program is shown below.

Tim Barry, President, CEO and director of Silver Bull states, "The purpose of the twinning program is to raise confidence in the complete long hole data set comprised of over 2,700 holes. This current batch is mostly targeting holes that are situated within the lower grade halo in between the high grade structures which typically average intercepts greater than of 120g/t silver. We have now twinned close to 150 long holes and have received just under half of the results from the lab. We are very pleased with the correlation of these holes with the historical data set in the silver zone, and now plan to move one of the drills into the high grade zinc zone to firm up the historical data within the week."

About the Shallow Silver Zone: 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.

Zinc Exploration Target: 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 >20% over the last 100 years.

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.

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. Silver Bull also has 2 mineral licenses in Gabon, Central Africa, which are prospective for gold, manganese, and iron ore.

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 and 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 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.
