INNOVATION AND IMPACT.

Innogy has assembled a vast nickel tenement package in Tanzania, which is also prospective for lithium, cobalt, copper and gold. It totals 5,300 km² (comprising approximately 2,300 km² of granted tenure and 3,000 km² of pending tenure) and is spread across four highly prospective projects. Leading with the Northern Frontier, Western Frontier and Southern Frontier projects, Innogy are exploring for nickel sulphide mineralisation in a world-class setting, utilising the latest advancements in exploration technique and understanding to unlock the potential of one of the last underexplored Nickel Frontiers.

Northern Frontier

Nickel Project.

Innogy’s Northern Frontier Nickel Project can be found just 60 km northeast of the Kabanga Nickel deposit, the world’s largest development-ready high-grade nickel sulphide deposit, in an up-strike position of the Karagwe-Ankole Belt prospectivity corridor.

The Kabanga Nickel Deposit is the largest development ready high-grade nickel sulphide deposit in the world with a total Mineral Resource Estimate of 58.2 Mt at 2.62% nickel, 0.33% copper, 0.2% cobalt, resulting in an in-situ resource of 1.52 million tonnes of contained nickel, 190,000 tonnes of copper and 120,000 tonnes of cobalt.

The project is comprised of 2,400km² of prospecting licences (of which, over 1,400km² are granted) in the corridor, extending for 150 km strike length of the Kabanga-Musongati Alignment. These were selected based on favourable geology, geochemistry and geophysics for Kabanga-style nickel sulphide mineralisation. This significant area is the largest such landholding by a single company in the region, positioning Innogy to be a significant force for nickel exploration in Tanzania.

In addition to nickel, Northern Frontier also holds potential for lithium and cobalt mineralisation, with the lithium associated with pegmatites that could potentially be present in the area, due to a similar geological setting as AVZ Mineral’s Manono Lithium and Tin project in the DRC.

The region has not been subjected to significant exploration work, since BHP in the 1990’s. Therefore, Northern Frontier remains underexplored by many standards, and has not been the target of modern exploration techniques and understanding.

Thanks to EcoGraf, Innogy holds an extensive historic database of nickel exploration in the area. Included in this database are geological, geochemical and geophysical datasets from BHP’s work in the 1990’s.

Work at Northern Frontier is commencing with the reprocessing, re-interpretation and review of all data within the historic data set compiled by EcoGraf, to generate exploration targets; many of which have already been identified. These targets will be followed up with detailed surface geochemical sampling and geological mapping, coupled with additional geophysical surveys. Notable nickel anomalies will be fast tracked to drill testing.

Western Frontier

Nickel Project.

The Western Frontier Project is an under-explored nickel sulphide project in the southern end of the Kabanga-Musongati-Kapalagulu Alignment in the Ubendian Belt, 95 km southeast of the Kapalagulu nickel deposit.  The northern two tenements surround ASX listed RMI’s Kabulwanyele Nickel Project, which hosts the 2 km long Kabulwanyele nickel laterite, gossan occurrence, which overlies an ultramafic intruded within metasediments.  The Kabulwanyele nickel laterite remains open as it heads into Innogy’s tenure.  The Company’s tenure is home to approximately 30 km of the geophysical trend that runs southeast from Kapalagulu, through Kabulwanyele. 

Importantly for Innogy, the Kabulwanyele nickel laterite/gossan occurrence identified on RMI’s tenure, is open to the north, as it heads into Innogy’s tenure. Further to this, the Geological Survey of Tanzania geological mapping of the project area shows extensive laterite occurrences within Innogy’s tenure, which themselves have potential for nickel mineralisation, and given the parallels to the Kapalagulu nickel deposit to the northwest, there is the possibility of mafic/ultramafic intrusions beneath, which may be prospective for nickel sulphide mineralisation.  This presents Innogy with a focus for early exploration at Western Frontier with potential for near-term drilling.

The southern three tenements of Western Frontier are predominantly prospective for gold, with numerous occurrences of gold being recorded by the Geological Survey of Tanzania, within the tenements. These are predominantly characterised as being hydrothermal vein hosted gold.

Minimal historic work has been completed at the project, with work limited to surface geochemical samples.  As with the Company’s other nickel projects, the Western Frontier Project will, subject to the grant of the prospecting licences, be systematically explored using the latest advancements in exploration with the aim of uncovering any mafic/ultramafic intrusions at the project that may be host to nickel sulphide accumulations.  

Southern Frontier

Nickel Project.

The Southern Frontier Nickel Project is an under-explored package of ground prospective for nickel sulphide mineralisation.  The project totals an area of almost 900 km² in the mafic-felsic granulite complex of the late Proterozoic Mozambique Belt, 20 km southwest of the town of Mahenge in south-eastern Tanzania.

The tenements were selected primarily for nickel exploration, with the aim of targeting a Ntaka Hill style of deposit, a typical magmatic nickel sulphide deposit, due to its similar stratigraphical setting and shared geophysical and metamorphic characteristics.  Ntaka Hill itself is located in southeast Tanzania and shares many similarities with the world class Thompson Nickel Belt in Canada.  The similarity to Ntaka Hill, also creates prospectivity for cobalt mineralisation.

The presence of artisanal alluvial gold workings in the Southern Frontier Project area indicates a source for this gold must be present in the vicinity.  The area hosts prospective lithologies at suitable metamorphic grades providing potential for shear-hosted lode-gold mineralisation as well as nickel.

The area is largely unexplored, with only minimal low resolution regional geological mapping and geophysical datasets available.  Innogy therefore have a unique opportunity to be the first exploration team on the ground exploring the area. A detailed programme of grassroots exploration is planned for the project, including remote sensing, airborne geophysical surveys and surface geochemical sampling.

Golden Eagle

Gold Project.

Golden Eagle is a gold project located on the eastern margin of the +70 Moz gold endowed Archean Lake Victoria Goldfields, within the same structural corridor as the Golden Pride Mine. The project covers an area previously occupied by part of Tanga Resource’s Hanang Gold Project, who defined a number of gold prospects within the ground, and identified the high-grade Winston deposit, in the neighbouring tenements. Gold in the area is hosted within veined shear zones within BIFs.

Innogy’s tenements include the direct interpreted northeast continuation of the BIF that hosts the Winston deposit, which includes drilling intercepts of 16m @ 55g/t Au from 116m. Along with numerous faults and shear zones throughout the project, that crosscut the BIF units.

The Company’s tenements are under-explored, in comparison to the neighbouring prospects and the rest of the Lake Victoria Goldfields, with work limited to initial prospect generation. The Company plans to complete a detailed gold prospectivity review of the tenements, leading to a refreshed prospect list. This will initially be investigated with surface geochemical and geophysical field programs, with the aim of generating priority drilling targets.
