There now seems little doubt that there was enough sulphur in the magma to form a metal sulphide liquid phase.

From his study of the latest core samples,
- Presence of Cumulate rocks
- Sulphide liquid fractionation
The observation of sedimentary grains of silica in the gabbro again confirms that Karoo sediments (including sulphur rich coal measures) were incorporated into the magma. This is supported by the sulphur content of the samples which are generally well above average values for magmatic gabbro. For example, one sample recorded a sulphur value of 18,700ppm.

Note to Editors:
Dr Prendergast is an independent geologist and consultant. He is recognized as a leading authority on magmatic sulphides worldwide with particular expertise on copper-nickel-PGE deposits in Southern Africa. He is the author of numerous academic papers on the subject. He has been a consultant of Kavango Minerals since 2014.

The area covered by Kavango's KSZ licences displays a geological setting with distinct similarities to that hosting world class magmatic sulphide deposits such as those at Norilsk (Siberia) and Voisey's Bay (Canada).
The Norilsk mining centre is about 2,800km northeast of Moscow and accounts for 90% of Russia's nickel reserves, 55% of its copper and virtually all of its PGMs. Kavango's licenses in the KSZ display a geological setting with distinct geological similarities to the magmatic sulphide deposits at Norilsk. Magma plumbing systems are a key feature of these deposits.
When a deposit consists almost entirely of sulphides it is termed "massive". When it consists of grains or crystals of sulphide in a matrix of silicate minerals, it is termed "disseminated".
Gabbro/gabbroic: A coarse grained, medium to dark coloured rock, formed from the intrusion of mantle derived molten magma into the earth's crust. Gabbroic rocks (or "gabbros") formed as the molten magma cooled.
Gabbroic sills: Relatively thin, planar bodies of solidified gabbroic magma that intruded into layers of sedimentary rock whilst still molten.
High-level sills: Are sills that are emplaced in the upper levels of the earth's crust, close to the surface.
Karoo: The Karoo System covers 1.5 million km2 of the semi-desert region region of Southern Africa. Rocks in this system formed 180-310 million years ago.
Magma Plumbing System: Magma plumbing systems are composed of stacked horizontal sills connected to each other via vertical dykes. A continuous flow of magma (containing "free" sulphur) through a magma plumbing system may have allowed the accumulation of metal sulphides in certain trap sites within the sills. This is because metal sulphides are heavy and tend to sink to the bottom of magma. Over time, accumulations of metal sulphide could have led to the formation of economic deposits of Copper-Nickel-PGMs.
Primary sulphides: Are sulphide complexes (or crystals) that form as the magma cools and are composed of elements that are present at the time of initial crystallization. Secondary sulphides may form after the magma has solidified either by the introduction of new elements into the rock or by re-mobilising elements already present through changes in pressure, heat etc.
Sulphide mineralisation: If there is sufficient sulphur in the molten magma, it will tend to combine with metals (Cu, Zn, Ni, Co, Pb, PGEs etc.) to form metal sulphide complexes, which may coalesce to form massive sulphide deposits. If the melt is sulphide poor, the metals will be taken up into the silicate minerals that form as the magma cools and will not usually form economic deposits.
