The high grade 22 Zone is located 20 kilometers northwest of the Solwezi Dome and is less than 10 kilometers from the western mine gate of the Kansanshi Mine complex. The 22 Zone was discovered by follow up shallow drilling in 2012 over a subtle copper anomaly and thick overburden. Drill campaigns in 2013 (reverse circulation) and 2014 (diamond drilling) extended the high grade, near surface discovery.
Drill Hole SLZ-DD-14-010 at 22 Zone; 5.71% Cu over 14.2 (11.3 true) meters.
In an attempt to detect the underlying source of the oxide mineralization at the 22 Zone, 6.7 kilometers of NSAMT geophysics was run in the vicinity, and a conductive zone was indicated. To date, this conductive zone has not been drill tested.
It is currently thought that the 22 Zone and environs may be underlain by a basement dome similar to those at Kansanshi and Solwezi. This doming is believed to be intimately associated with the processes resulting in the copper mineralization at those sites. A deep drill test around the 22 Zone is planned to test for evidence of favourable lithology and stratigraphy once additional geophysics is carried out.
