KSZ drilling update

Kavango Resources plc (LSE:KAV), the exploration company targeting the discovery of world-class mineral deposits in Botswana, is pleased to announce that Kavango's senior geologist on site has reported that diamond drilling on Hole TA2DD002 intersected what appears to be sulphide and chromite mineralisation in pyroxenite at 651m from surface.

Hole TA2DD002 is currently being drilled in the northern (Hukuntsi) section of the Company's project in the Kalahari Suture Zone ("KSZ").



Ø The geological diamond drill Hole TA2DD002 was designed to intersect the Proterozoic (Tshane Complex) mafic/ultramafic intrusion that lies beneath Karoo sediments intruded by gabbros to obtain supplementary geophysical and geological data

Ø Kavango previously estimated that the Proterozoic rocks would be intersected at between 600m and 700m

Ø The principal objectives of the hole were to collect physical data from the Karoo and Proterozoic intrusives to support and refine Kavango's 3D geophysical model of the KSZ in the Hukuntsi Section

Ø At 651.78 the drill passed from Karoo tillites (glacial sediments) through an unconformable contact into fresh Proterozoic pyroxenite (ultramafic magmatic rock)

Ø Visual inspection of core has been carried out by the Company's senior geologist at the drill site

Ø The very coarse (pegmatitic) pyroxenite appears, on visual inspection, to contain disseminated chalcopyrite (copper sulphide) and chromite, as well as section of coarse anorthosite

Ø Hole TA2DD002 is currently at 701m and remains in Proterozoic ultramafic magmatic rocks

Ø On completion of the hole, core samples will be cut and samples sent to an internationally accredited laboratory in South Africa for a suite of relevant assays.


Ben Turney, Chief Executive Officer of Kavango Resources, commented:

"We made immediate contact with ultramafic magmatic rocks and visible sulphides, as the Proterozoic was intersected at 651m . The presence of chalcopyrite (copper sulphide) is an indicator of further potential mineralisation in the system, though quantities and grades are yet to be determined.

While this is an encouraging development in our efforts to prove the concept of the Kalahari Suture Zone, important steps remain for us to evaluate thoroughly what we have discovered.

We expect to continue drilling Hole TA2DD002 further into the Proterozoic structure and are in discussions with Mindea and Equity Drilling about the further depth that can realistically be achieved. Once drilling is complete on Target Area A we will mobilise the rig to Target Area B. In parallel to this we will send core samples collected from Target A for relevant assays and whole rock analysis."

Note to Editors:


Kavango's 100% subsidiary in Botswana, Kavango Minerals (Pty) Ltd, is the holder of 14 prospecting licences covering 7,573.1km2 of ground, including 12 licences over a significant portion of the 450km long KSZ magnetic anomaly in the southwest of the country along which Kavango is exploring for Copper-Nickel-PGM rich sulphide ore bodies. This large area, which is entirely covered by Cretaceous and post-Cretaceous Kalahari Sediments, has not previously been explored using modern techniques.

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.


EM Super Conductors: are bodies of highly conductive minerals such as graphite, magnetite and metal sulphides, which conduct electricity very rapidly provided the mineral grains are in contact with each other.

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") are formed as the molten magma crystallizes and cools.

Gabbroic sills: Relatively thin, planar, horizontal bodies of solidified gabbroic magma that intruded into layers of sedimentary rock whilst still molten.

Karoo: The Karoo System covers 1.5 million km2 of the semi-desert region of Southern Africa. Rocks in this system formed 180-310 million years ago.

Massive sulphide: 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".

Metal/Magmatic sulphide: Deposits of sulphide mineral concentrations in mafic and ultramafic rocks, derived from immiscible sulphide liquids. To view a video of how metal/magmatic sulphides form please visit -  

Norilsk Style: copper/nickel/PGE mineralisation associated with the intrusion into the upper parts of the Earth's crust of mafic magma, which form magma chambers that sit below volcanic vents or fissures that extrude basaltic lava onto the surface (Hawaii is a possible modern equivalent). The Norilsk intrusions tend to have distinct morphologies, combining thin gabbro sills (wings) with deep keels (thought to be associated with feeder dykes) at the base.

Norilsk Model:   a genetic geological model similar to that pertaining to the Norilsk/Talnakh deposits in Siberia. Traditionally, it was thought that, during emplacement, the magma incorporated sulphur rich country rock (e.g. coal measures) or evaporites into the melt, which allowed the molten magma to become sulphur saturated. The free sulphur would then combine, preferentially, with Cu/Ni/PGE metal ions to form metal sulphides, which, being heavy, tended to accumulate in traps or into the keel of the magma chamber. However, modern research suggests that the process might be more complex and may also involve changes of the chemical and physical properties of the magma during the introduction of new pulses of molten material from below. Such sudden changes may have caused rapid segregation of metal sulphides within and above the feeder dykes within the keel of the intrusion.

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.
