The Company has exploration rights on the Bisha and Harena Mining Licenses and the Mogoraib Exploration License (see figure in Overview). Bisha continues aggressive exploration to expand resources and discover new mineral deposits that have the potential to extend mine life for the Bisha mill. Targets are presented on figure to the right. Overviews follow of the known mineralization (not in reserve).
- Northwest Zone
The Northwest Zone VMS (volcanogenic massive sulphide) lies within the Bisha mining license. The Northwest Zone is 1.2 km from the Bisha Mine deposit. Bisha views the Northwest Zone as a potential source of supplemental feed for the processing plant at Bisha. The feed would provide additional cash flow as an extension to mine life without significant capital expenses.
Geological mapping of the Bisha area in 2002 identified altered felsic volcanic rocks existed within 2km to the northwest of the Bisha Mine zone with coincident airborne EM signatures. In the fall of 2003 diamond drilling intersected potentially economic widths of copper, gold and silver massive sulphide mineralization. Follow up drilling in 2004 - 2006 and 2012-2013 identified copper and zinc VMS mineralization over a strike length of 600m that remains open to the northeast and the southwest.
Resources - NW Zone
Hambok VMS is a satellite base metal deposit 16 km away from the Bisha mill on the Mogoraib River exploration license. Bisha views the Hambok deposit as a potential source of supplemental feed for the processing plant at Bisha. The feed would provide additional cash flow as an extension to mine life without significant capital expenses.
The Hambok massive sulphide body is a steeply east dipping, lenticular body consisting of a series of lenses. The massive sulphide body extends for over 1,000m along strike, approximately 350m down dip and is up to 75m thick in the center of the lens. The ore body remains open along strike to north and south and down dip at depth.
