nov 15 news release Vancouver, British Columbia - Silver Bull Resources, Inc. (TSX: SVB, NYSE MKT: SVBL) ("Silver Bull") is pleased to announce the drill results for the ninth 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 ninth batch of 11 drill holes include:
- Hole T12090: 15.05 meters @ 463.55g/t Ag (including 3.1m @ 1654.92g/t Ag)
- Hole T12080: 30.50 meters @ 131.34g/t Ag (including 7.6m @ 405.78g/t Ag)
- Hole T12091: 32.55 meters @ 94.10g/t Ag (including 2.9m @ 303.31g/t Ag and 4.3m @ 233.18g/t Ag)
- Hole T12089: 13.85 meters @ 64.48g/t Ag (including 1m @ 546g/t Ag)
** Mineralization remains open in the north, south, east, and westerly directions
The 3,000 meter drill program currently underway at Sierra Mojada uses two underground "Termite" rigs to twin a historical long hole data set with diamond core along a high grade silver zone at the eastern end of the Shallow Silver Zone. 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 is scheduled to conclude before the end of the 2012 calendar year. Upon completion, Silver Bull will initiate a revised NI43-101 resource update on the Shallow Silver and Zinc Zones, scheduled for release in first quarter of 2013.
In addition the high grade silver zone, and as announced in the September 14, 2012 news release, Silver Bull has also expanded the underground twinning program with an additional 2,000 meters of drilling into the high grade zinc zone, which is also largely defined by long hole drilling and sits adjacent to and below the silver mineralization. Initial drill results from the twinning program in the zinc zone are expected by late November 2012.
A table of holes T12080 to T12091 from the underground long hole twinning program is shown below.
