Zone 5 Resources and Exploration

Cupric has focused on delineating and expanding Zone 5's high grade Cu-Ag resources since acquiring the Khoemacau Project in 2013. The deposit's sediment-hosted, stratiform Cu-Ag mineralization is hosted in the D'Kar Formation near the contact with the underlying Ngwako Pan Formation. The hanging wall-footwall redox contact is a distinctive target horizon that consistently hosts Cu-Ag mineralization.

The D'Kar-Ngwako stratigraphic sequence, which is covered by 2 to 60 meters of Tertiary-age Kalahari Group sands, has undergone a progression of regional folding, shearing, and thrust faulting. This structural deformation has led to multiple episodes of pervasive mineralization and enrichment that has been upgraded by an extensive system of quartz and quartz-carbonate shears, as well as zones of brecciation. As a result, the Cu-Ag mineralization is relatively continuous along 4,200 meters of strike length and to depths greater than 1,200 meters. Notably, some of the best intersections to date have been drilled in the last line of deep holes.

Over 199,000 meters of drilling have been completed by Cupric and previous operators at Zone 5, which has MI&I sulfide resources at a 1.0% Cu cut-off of 100.3 million tonnes @ 1.95% Cu and 20 g/t Ag (~43% of the tonnes and contained metal are measured & indicated). The mineralization is predominately bornite, chalcocite, and chalcopyrite. In 2015, Cupric's drilling (at times with 27 rigs active on the property) increased the total contained Cu by 39%. Zone 5 is open along strike and down dip.
