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.

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.

The strata-bound orebody with an average width of 10 meters, a strike length of 4.2 kilometers, a dip of 56 to 60 degrees and competent stratigraphy lends itself to lowcost underground mining with no back-fill required.

The stratiform Cu-Ag mineralization is ideally suited to large scale, mechanized sub-level open stoping with the ore zone dipping ~60°, and averaging a width of 9-10 meters over 4,200 meters of strike length. The mine will produce ore at an average fully diluted head grade of 1.75% Cu and 16 g/t Ag*, which will be hauled to Boseto for treatment.

The Boseto concentrator will be upgraded from its current 3.0 million tonnes per annum nameplate capacity to 3.6 million tonnes per annum to treat the Zone 5 ores. The ores respond well to conventional sulfide flotation, producing a high-grade ~42% copper concentrate. The concentrate will be road hauled to port for shipping and sale on the international market.
