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.

Silver Bull president, CEO and director Tim Barry said: "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."
