Haneti Nickel Project- Airborne Geophysical Data Interpretation Results

Kibo Mining Plc ("Kibo" or the "Company") (AIM:KIBO; JSE AltX: KBO), the Tanzania focused mineral exploration and development company, is pleased to announce that it has received positive preliminary results from an independent Airborne Geophysical Data Interpretation carried out over its Haneti project in central Tanzania. The interpretation used recently acquired high resolution data acquired from the Geological Survey of Tanzania (see RNS of the 13(th) March 2015). Data processing and interpretation was carried out by Spinifex Geophysics of Perth, Western Australia.

Highlights

-- High resolution magnetic and gravity data show the interpreted aerial extent and geological structure of the Ni-Cu-PGM prospective Haneti-Itiso Ultramafic Complex (HIUC) confirming its continuity over 80 kilometers of strike length;

-- A number of other areas have been identified within the HIUC showing similar magnetic and gravity signatures as the known ultramafic outcrops e.g. Mihanza and Mwaka Hills, and which can be confidently interpreted as new areas of sub-cropping ultramafic rocks and targets for follow up exploration;

-- The interpretation results resolves some of the internal geological structure of the HIUC, showing it is comprised of a number of attenuated and folded ribbons of ultramafic rocks within the general granite-gneiss country rock which will assist geological interpretation and help focus exploration on areas with best potential;

-- The interpretation has identified a new zone of ultramafic rocks over a strike length of approximately 30 km similar to the HIUC, which will be a new target zone for follow up exploration;

-- The results will allow Kibo to further rationalise the Haneti project by relinquishing areas where no ultramafic target rocks prospective for Ni-Cu-PGM style mineralisation are indicated;

Louis Coetzee, Chief Executive Officer of Kibo Mining plc, said: "We are extremely pleased with the results emerging from this geophysical interpretation, which significantly enhanced our understanding of the geological structure of the Haneti project at minimal cost. The results will allow us to identify further priority areas for follow-up work and from which additional drill targets similar to those already defined at Mihanza and Mwaka Hills for Ni-Cu-PGM style mineralisation will be developed.

The latest results reconfirm our strong belief in the significant potential of Haneti and its considerable prospectivity. We believe Haneti can generate significant value for shareholders through future work programmes, which amongst others includes a priority first phase drill programme and potential subsequent project partnerships.

We are pleased to see the Haneti project come into its own and take its place as a driver of shareholder value alongside our Mbeya Coal to Power Project and our Imweru Gold Project. Further updates across the Company's portfolio are expected to follow shortly."

Airborne Geophysical Survey Interpretation Results

Introduction

Kibo acquired high resolution airborne geophysical survey data (magnetic, gravity and radiometric) from the Geological Survey of Tanzania (GST), covering its wholly owned Haneti project in central Tanzania. Following an initial in-house review, the data was forwarded to the Perth based geophysical consultants Spinifex Geophysics for detailed processing and interpretation to assist with the further understanding of the geology of the project and generate new target areas particularly for Ni-Cu-PGM style mineralisation. The decision to proceed with this work followed on from the results (see RNS of the 27(th) January 2015) of an independent geochemical interpretation report which identified the Mihanza Hill area as a prime drill target for Ni-Cu-PGM style mineralisation, and by implication the potential to locate other similar targets within the project on strike and adjacent to Mihanza Hill within the nickel sulphide prospect Haneti-Itiso Ultramafic Complex (HIUC).

Detailed Results

Digital processing of the geophysical data to produce a number of high resolution images over the Haneti project has enabled a detailed geological interpretation to be carried out by independent geophysical consultant Steve Massey, Spinifix Geophysics of Perth, Western Australia. Specifically, the results have permitted a more detailed picture of the sub-surface extent and geological structure of the Ni-Cu-PGM prospective Haneti-Itiso Ultramafic Complex (HIUC) be modeled which will assist with more focused targeting for follow up exploration and definition of drill targets. The interpretation confirms that the HIUC extends over a strike length of up to 80 km as a series of broadly northwest-southeast trending attenuated and folded ribbons of ultramafic rocks within the general granite-gneiss country rock. Kibo's exploration programmes to date have concentrated on the central 25 km of this nickel prospective rock sequence (equivalent to approximately 31% of the entire HIUC strike length) where it has already established drill targets at Mihanza Hill and Mwaka Hill that it plans to drill during 2015. The geophysical signatures of the outcropping Mihanza and Mwaka targets can be clearly seen in the interpretation and have helped to infer extensive zones of sub-cropping ultramafic rocks of similar composition through the HIUC. This will permit the identification of the priority areas for follow-up mapping, soil sampling, and ground geophysical surveys to develop other drill targets similar to Mihanza & Mwaka. A notable feature from the interpretation is the complexly folded internal structure of the HIUC which is most clearly interpreted from the magnetic data and extends the sub-cropping footprint of the HIUC over a wider area than previously interpreted. This feature is common in similar nickel prospective ultramafic sequences in East Africa and, while making the geology more complex, may result in secondary enrichment resulting from re-mobilisation of primary sulphides as seen in other Ni-Cu-PGM style deposits globally.

In addition to assisting with a more detailed resolution of the HIUC, the geophysical interpretation has also indicated a new zone of northwest-south east trending mafic-ultramafic rocks in the south-west of the surveyed block over 30 km strike. These rocks provide the Company with a new target zone prospective for Ni-Cu-PGM style mineralisation similar in structure to the HIUC.

The Company is continuing to work with Spinifix to carry more detailed modelling and interpretation work on the geophysical data to extract as much information as possible pertaining not just to the Ni-Cu-PGM potential but also the gold and lithium-niobium-tantalum potential of the project. Specific modelling on the Mihanza and Mwaka drill targets will be undertaken prior to drilling, to optimally locate the proposed drill holes on these prospects. This approach is consistent with our strategy to obtain the maximum information from our exploration database on Haneti by focussed desk studies carried out both in-house and by experienced consultants prior to recommencing field exploration including drilling.

An additional benefit from this geophysical interpretation is that it will permit the Company to continue to consolidate the Haneti tenement package.

Background Technical Information

During 2012/2013 the GST commissioned high resolution aero-geophysical surveys over parts as central and southern Tanzania. The surveys comprised the collection of magnetic, gravity, radiometric and electromagnetic data. The electromagnetic data (VTEM Survey) was only carried out over selected areas within the survey blocks. The magnetic and radiometric surveys were flown on a line spacing of 250 m while the gravity was flown on line spacing of 2.5 km. The surveys were carried out by Geotech Airborne Limited and Sander Geophysics Limited and data quality control was done by the British Geological Survey in collaboration with the GST. Pleasingly, the survey blocks covered the Company's nickel, gold and lithium prospective Haneti project and survey data has recently been made available for purchase by private companies.

This data is of significantly better quality than the 1970's regional data already available for Tanzania as a result of improvements in data acquisition techniques, closer line spacing and the inclusion of airborne gravity and electromagnetic data which were previously unavailable. This new geophysical data, when combined with the Company's extensive existing field exploration database, is now enabling a more detailed understanding of the geological structure of Haneti including an improved interpretation model of the sub-surface extent of HIUC which comprises the target rock formation for Ni-Cu-PGM style mineralisation. The geophysical interpretation is assisting the Company to target areas for follow up infill and extension sampling as recommended in the recent geochemical interpretation report (see RNS 27 January 2015) as well as helping with a better understanding of the existing drill targets particularly at Mihanza and Mwaka Hills prior to drilling.

It should be noted that the Mihanza Hill target in particular has been identified from this recent geochemical interpretation report as showing surface soil and rock sampling results in key elements (Ni ,Cu, Cr & PGMs) characteristic of a mineralised "chonolith type" intrusion and is considered a priority drill target. The nature of this "chonolith" model of mineralisation is that the host intrusion often shows a complex pipe-like geometry with a relatively small subsurface footprint and comprising a number of irregular mineralised bodies within the mineralised district. Careful interpretation of the airborne geophysical data should assist with refining this model and potentially identifying similar type targets to Mihanza within the HIUC, which is currently interpreted to extend up to 8o kilometres along strike.

As the aerial extent of the geophysical survey data covers the entire Haneti project as well as peripheral areas, the interpretation is assisting the Company with acquiring a greater understanding of the regional geological setting of the project with regard to its overall prospectivity for not just Ni-Cu-PGM style mineralisation but also for gold and pegmatite related lithium mineralisation for which the Company has also had encouraging indications from sampling to date.

Maps showing the location of the prospects discussed above and a preliminary geophysical interpretation map of the central Ni-Cu-PGM prospective area can be found on the Haneti project page of the Company's website (www.kibomining.com).
