Ditau assay results
Kavango Resources plc (LSE: KAV), the exploration group listed on the Standard List segment of the main market of the London Stock Exchange and targeting the discovery of world class mineral deposits in Botswana, confirms that the assay results from the two holes drilled at the Ditau Camp prospect have been received from Genalysis Laboratories in Australia.
· A total of 489 core samples were prepared by Intertek Laboratories in Johannesburg and assayed for 65 elements by Genalysis Laboratories in Australia using aqua regia digest with ICP finish. Genalysis carried out 12 duplicate check assays, ran 14 control standards and 14 blanks during the assay run.
· Kavango is currently undertaking its own program of checks and duplicates at an independent laboratory.
Michael Foster, Chief Executive Officer of Kavango Resources, commented:
"We are pleased to have received the assay results from the two drill holes at Ditau. Kavango is now completing its own check assays at an independent laboratory in South Africa, which is normal industry practice. We will then be in a position to fully check, assess and interpret the results so as to formulate our plans for Ditau.
Currently Kavango's preferred option would be to farm-out this project to an industry partner, mainly due to its' size, plus the fact that our main focus remains the Kalahari Suture Zone ("KSZ") structure in southwest Botswana where drilling is expected to commence later this quarter".

Notes for Editors:
Kavango's 100% subsidiary in Botswana, Kavango Minerals (Pty) Ltd, is currently the holder of 17 prospecting licences covering 10,347.2 km2 of ground, including most of the 450km long KSZ magnetic anomaly in the southwest of the country along which Kavango is exploring for Cu-Ni-PGE rich sulphide orebodies. 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 the World Class Norilsk Ni-Cu-PGE orebodies in Siberia.
Kavango's exploration model is based upon the search for magmatic massive sulphide orebodies buried beneath up to 200m of overburden. The identification of drill targets follows a carefully constructed exploration program specifically developed by the Company for exploration in areas covered by Kalahari and Karoo sediments and sands.
The exploration program is initiated by identifying the location of magmatic intrusive rocks from an analysis of the regional magnetic surveys published by the Botswana Government. This is followed by an airborne electro-magnetic survey (AEM) carried out over the magnetic anomalies that have signatures indicating the presence of intrusive rocks at depth. By using the latest generation of low frequency helicopter-borne EM surveying, conductors lying below the Kalahari/Karoo cover can be identified for further investigation. These conductors can be tested on surface by very high sensitivity soil sampling*, which can detect metal ions transported from buried, metal rich massive sulphide deposits associated with the emplacement of magmatic intrusive rocks.
Kavango uses a ground based geophysical technique known as Controlled Source Audio frequency Magneto Tellurics (CSAMT)** to identify the exact location of the conductors. The shape, orientation and depth of the conductors will determine if the conductor should be drilled. The presence of a metal in soil anomaly is also used to prioritise the conductors.
The next phase of the exploration involves the drilling of the conductor to determine the presence of sulphide mineralisation and its metal component (discovery). This is followed by the evaluation of the discovery, which will determine whether the deposit is large enough and rich enough to make an economically viable mine (feasibility).
*Kavango geologists have pioneered a high resolution soil sampling technique to detect ultra-fine metal particles which have been transported in solution from considerable depths of burial to the surface by capillary action and transpiration. Evaporation leaves the metal ions as accumulations within a surface "duricrust" which is then sampled and analysed. Zinc, which is the most mobile of the base metal elements (i.e. goes into solution easily) acts as a pathfinder to mineralization at depth.
**Massive sulphide (base metal) deposits can be detected by CSAMT because they conduct electricity easily (conductors) as opposed to silicate wall rocks (resistive).
