("Katoro" or "the Company")
Within the boundaries of this 5,000 sq. km project, Katoro have identified precious, base and strategic metal prospectivity and, in the opinion of the Katoro Board, Haneti is capable of delivering a number of discrete large-scale exploration and development opportunities.
I look forward to articulating our project strategies and operational plans in the coming weeks."
· Haneti is a polymetallic system with identified potential for nickel (sulphide and laterite), Platinum Group Metals ('PGMs'), copper, gold, lithium and rare earth elements ("REEs");
· The principle target zone is an 80 km long ultramafic belt with grades from surface sampling of up to 13.6% nickel and 2.33 g/t combined platinum and palladium
o Nickel and palladium have experienced significant price strength of late with nickel now trading at circa
· Within the 80 km ultramafic belt is the principle target, Mihanza Hill, where 2015 geophysical work identified significant extensions to nickel sulphide prospective target rock formations and geochemical interpretation has identified prospectivity for chonolith type nickel-copper-PGM mineralisation;
o Mihanza Hill is believed by the Company, based on desktop work undertaken, to have the potential to host a similar style of mineralisation to the Sipa Resources Limited (ASX:SRI) Akelikongo nickel project in
· Also, within the Haneti licence area there is identified greenstone gold potential to the west, where there is extensive artisanal gold mining in an area a few kilometres to the east of Shanta Gold's 0.7 million ounce Singida project;
· Furthermore, the Project has the potential for lithium, tantalum niobium and REE mineralisation demonstrated by host pegmatites in an area where sampling has returned a high-grade sample of 2.6% lithium and strongly anomalous results in niobium and tantalum;
· Further information in respect of Haneti exploration plans will be provided over the coming weeks with announcements in respect of nickel-copper-PGM, gold and lithium-rare earth exploration plans.
Haneti Project Background
· Katoro's Haneti project covers an area of approximately 5,000 sq. km located in central
· The Project is favourably located for various styles of mineralisation due to its geology comprising part of the margin of the Tanzanian Craton (major c. 2.5 billion-year old crustal block) where it has been overthrust by younger rocks as part of a major crustal plate collision zone.
· The Project has significant mineral discovery potential due to this favourable geological setting and this has been demonstrated by the results of historic exploration carried out over the area by previous operators.
Haneti Project Mineralisation
Principal styles of mineralisation indicated for Haneti are outlined below.
Nickel, Copper and PGMs
The Company has been undertaking a review and analysis of all historic work completed on the Haneti project and believe that it could host a chonolith type nickel sulphide deposit.
Prospectivity for nickel, copper and PGMs (e.g. platinum, palladium, rhodium and others) is associated with a linear NW-SE trending zone of iron and magnesium rich rocks (ultramafics), the
Exploration to date has focussed on the Ni-Cu-PGM mineral potential of the Project with two well defined drill targets ready for testing, one at a location where a surface sample returned grades of 13.6% nickel, 0.4 ppm platinum and 1.9 ppm palladium from an iron rich shallow pit sample. Geophysical and geochemical processing and interpretation of exploration data by independent consultants at this location have shown compelling evidence that the rocks underlying this area are fertile for potential Ni-Cu-PGM accumulations.
The Haneti project was the subject of an independent geochemical interpretation in 2014, which identified the Mihanza Hill area as a prime drill target for Ni-Cu-PGM mineralisation. The findings from the geochemical interpretation report and the in-house review thereon was sent to
In 2012/13, the
At the primary target, Mihanza Hill, a high magnetic anomaly was modelled by Western Geophysics using a 3D inversion modelling technique to better understand how the magnetic signature varied with depth. The results indicate that there is a considerable 'root' to the Mihanza Hill ultramafic outcrop, which points to a large volume of rock that could have positive implications for the differentiation of nickel sulphide rich magmas and provides a large volume of nickel prospective target rock at this location.
Follow up soil sampling has since been undertaken in the central part of the HIUC, the results of which were announced by Katoro on
Following further review of the accumulated work undertaken, the next step is to implement a drill programme for nickel sulphide at two of the Project's key targets: Mihanza Hill and
Greenstone gold potential has been demonstrated in the western part of the Project, where there is on-going extensive artisanal gold mining in an area proximal to Shanta Mining's circa 0.7 million-ounce
Greenstone hosted gold mineralisation is host to many of the World's largest gold mines and more locally is found at
The next phase of work will be to identify priority target sub- areas for detailed exploration within the large gold prospective area on the Project through initial geophysical interpretation studies.
Nickel mineralisation is found from the weathered products of the HIUC in the form of oxide mineralisation known as nickel laterites on the central hill outcrops of the HIUC where there is active artisanal mining for the semi-precious nickel mineral, chrysoprase. The Project's potential to host economic quantities of nickel as nickel laterites has not been fully evaluated from exploration to date. The potential of
Further work to evaluate the nickel laterite potential would comprise drilling across the known laterite areas on the Project to characterise the depth, composition, grade and tonnage present.
Lithium, Tantalum, Niobium & REEs
Lithium, tantalum, niobium and REE mineralisation can associated with the final stages of granite intrusions solidifying as linear bodies of rocks known as pegmatites.
The potential for this style of mineralisation demonstrated by the identification of host pegmatites in the region where a surface sample at one location returned a geochemical analysis result of 2.6% lithium and strongly anomalous results in niobium and tantalum. The grades from this sample are at potentially economic values contingent on sufficient ore tonnages of similar grades being discoverable.
The next phase of work here would be to identify the extent of the prospective pegmatite rocks on the project and their potential through mapping, trenching/sampling and ultimately drilling.
Current Haneti Project Ownership Structure
Katoro has a 75% interest in Haneti. Development of Haneti is being advanced in tandem with its joint venture partner, Power Metal Resources plc (LON:POW) ("Power Metal"), which has the remaining 25% interest in Haneti and a right to acquire a further 10% interest from Katoro to increase its interest to 35%, through a cash payment of
