Haneti Nickel Project- Airborne Geophysical Data Acquisition

 

 

 

Kibo Mining Plc ("Kibo" or the "Company") (AIM:KIBO; JSE AltX: KBO), the Tanzania focused mineral exploration and development company, is pleased to announce the Company has commenced an Airborne Geophysical Data Review in respect of the Company's Haneti Nickel Project.

 

Highlights

 

·    Recently flown high resolution aerial geophysical survey data acquired from the Geological Survey of Tanzania for the Haneti project

 

·    Detailed processing and interpretation of this data by a geophysical consultant experienced in Ni-Cu-PGM style mineralisation targeting, will now commence

·   Result of the work will assist with regional geological interpretation, help generate additional target areas for Ni-Cu-PGM style mineralisation and contribute to a better understanding of existing drill targets on the project prior to drilling

·   Data acquisition represents significant boost to exploration at Haneti as it represents a large cost saving relative to Kibo independently commissioning the flight survey.

 

 

Louis Coetzee, Chief Executive Officer of Kibo Mining plc, commented: "The Company's Haneti Nickel Project has delivered increasingly diverse and attractive results. Our main focus has been on identifying the potential for a large Nickel Sulphide deposit, however as outlined in previous announcements, Haneti is also evidently prospective for gold, PGMs, lithium and tantalum/niobium. 

 

The recently announced Geochemical Interpretation strengthened our confidence in the project significantly, which was borne from extensive previous exploration work on the ground.  Having access to this Airborne Geophysical Data will add considerably to our information about the project and enable us to conduct further project assessment, at minimal additional cost.

 

With historic exploration, Geochemical Interpretation and now Airborne Geophysical Data we are aiming to significantly enhance our understanding of the Haneti project and its considerable prospectivity. This will establish the basis from which significant value can be generated for shareholders through future work programmes and potential project partnerships.

 

We are pleased to advance the Haneti project in parallel to our work with prospective development partners at our Rukwa Coal to Power Project and our Imweru Gold Project.  Further updates across the Company's portfolio are expected to follow shortly."

 

Airborne Geophysical Survey Data Acquisition:

 

Kibo has acquired high resolution aerial geophysical survey data (magnetic, gravity, radiometric and electromagnetic) from the Geological Survey of Tanzania (GST), covering its wholly owned Haneti project in central Tanzania. It will now commission detailed processing and interpretation of this data from an experienced geophysical consultant to assist with the further understanding of the geology of the project and generate new target areas particularly for Nickel-Copper-PGM style mineralisation. The decision to proceed with this work follows the recently announced results (refer to RNS of the 27th January 2015) from 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).

 

Technical Information:

 

During 2012/2013 the GST commissioned high resolution aero-geophysical surveys over parts of 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 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, should enable 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 interpretation  report will then better assist the Company to target areas for follow up infill and extension sampling as recommended in the recent geochemical interpretation report  (Refer 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 l extent of the geophysical survey data covers the entire Haneti project as well as peripheral areas, the interpretation should also assist 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 can be found on the Haneti project page of the Company's website (www.kibomining.com).
