Dar es Salaam, Tanzania – Lifezone Metals is pleased to provide an update on progress on the Definitive Feasibility Study and resource definition drilling programme at the Kabanga nickel project (“Kabanga” or the “Kabanga Project”) in North-West Tanzania. We believe Kabanga is one of the world’s largest and highest-grade undeveloped nickel deposits, which is expected to offer a new source of more sustainable metals.
Following the appointment of DRA Global to undertake the DFS for the Kabanga Project and Kahama refinery, and to coordinate and manage input from all specialist consulting companies, study work is now underway across all technical disciplines.
Planning for Kabanga’s early works programme is progressing, which includes an aerodrome and internal roads infrastructure. The programme also includes the resource definition drilling programme on the North and Tembo portions of the Kabanga orebody to support the geological resource model and mine planning for the DFS.
Metallurgical and Refinery Testwork
DRA Global is advancing the metallurgical refining testwork programme using Lifezone Metals’ proprietary Hydromet Technology, which has the potential to significantly reduce carbon emissions in battery metals refining compared to traditional smelting and refining. Two POX leach tests were conducted to provide a preliminary indication of refinery metal recoveries. POX leach extractions for these non-optimised tests were: Ni 99%, Cu 97%, and Co 98% for POX test 1 and Ni 99%, Cu 99%, and Co 99% for POX test 2. These results indicate that Kabanga nickel concentrate is amenable to processing using Lifezone Metals’ Hydromet Technology.
Metallurgical testwork continues for the concentrator confirmation testwork and development of the refinery flowsheet. The scope of this work has been awarded to DRA Global’s in-house hydrometallurgical specialist team.
Environmental Management Plan and Infrastructure
Upholding international standards and frameworks is a key driver of Lifezone Metals’ Environmental Social Governance (“ESG”) strategy, particularly as the Kabanga Project is in definition phase. Both the Lifezone Metals and Tembo Nickel Corporation Limited (“Tembo Nickel”) teams are focused on uplifting the Environmental and Social Impact Assessment (“ESIA”) work to current international standards through gap analyses and additional studies over the next 12–18 months.
MTL Consulting Company Limited (“MTL”) completed updates to the Kabanga Environmental Management Plan and registered it with the National Environment Management Council (“NEMC”) in Tanzania. The Kahama Refinery ESIA studies have also advanced, with detailed studies underway.
Recently, Tembo Nickel signed an MoU with TANESCO for the supply of electricity to the Kabanga Project and Kahama refinery.
Work with other key Tanzanian infrastructure providers is progressing, including discussions with Tanzania National Roads Agency regarding upgrades to support the planned transport of concentrate from the Kabanga mine to Kahama refinery.
Following a site visit by the Tanzania Civil Aviation Authority, the aerodrome study has confirmed that the proposed area at the Kabanga site and presented design is suitable for an 80-seater aircraft1. Construction of the aerodrome and supporting infrastructure is planned to commence in 2023.

Since Tembo Nickel obtained Special Mining Licence SML 651/2021 (“SML”) in October 2021, field activities at the Kabanga Project have resumed, including the recommissioning of the camp and initiation of diamond drilling.
From the date of grant of the SML through the end of 2022, a total of 40 diamond drillholes were completed for a combined metreage of 13,094.5 m (“recent drilling”). This recent drilling was conducted over three campaigns:
- November 2021 through May 2022: Collection of metallurgical samples for the North and Tembo zones from 16 drillholes (4,218 m of diamond core). Nine of the metallurgical holes were drilled from surface (totalling 4,000 m) and the remaining eight holes were short wedges from existing parent holes. The resultant metallurgical bulk sample material has been sent to Perth, Australia for hydrometallurgical test work.
- June 2022 through November 2022: Confirmatory drilling at the Tembo and Safari zones totalling 21 drillholes (7,848.5 m of diamond core) to provide contemporary verification of the location and tenor of the previous results from historical drilling. This drilling largely comprised new from-surface holes (18 holes, 7,029.9 m), with the remaining three holes being wedges.
- In December 2022, an extensive programme of infill and proximate drilling was commenced. The primary focus of this work is to develop contemporary standards for input into the DFS.
This drilling programme, which commenced with three resource definition drillholes at the Tembo North zone (1,028 m), is planned to provide infill coverage as required along the full strike length of the known mineralisation at Kabanga, from Main zone in the south-west to Safari zone in the north-east – a total strike length of some 7.5 km.
In addition to resource definition drilling, this DFS drilling programme will involve the extensive collection of samples for geotechnical, metallurgical, and hydrological purposes.
We believe the results of the recent drilling have been encouraging, having largely confirmed the location, thickness, and tenor of previous results from historical drilling.
A list of the recent drilling completed on SML 651/2021 to the end of December 2022 is shown in Table 1, including, where assays are currently available, notable mineralised intercepts (including length-weighted average nickel-equivalent grade (NiEq) (%)). Any internal waste is included in the weighted average grade of the full intercept.
Assaying is routinely undertaken on 1.0 m samples, with reduction in sample length permitted to honour changes in lithology or style of mineralisation. Assaying is conducted at SGS laboratories in Johannesburg, South Africa and Mwanza, Tanzania. The analyses undertaken are Na peroxide fusion/ICP analysis; FA/ICP assays; sulphur analysis by ICP/Infrared/CS Analyzer; Ag by AAS; and SG determination by pycnometer. Check assaying of approximately 10% of the results is undertaken at Nesch Mintech laboratory in Mwanza, where Ni, Cu, and Co assays are undertaken by 4-acid microwave digestion with ICP/plasma-atomic emission spectrometer finish and sulphur analyses by Infrared/CS Analyzer. QA/QC insertion includes Certified Reference Materials standards, blanks, and pulp duplicates.
NiEq is calculated by Tembo Nickel using the formula: Ni% + Cu% x 0.411 + Co% x 2.765. Intercepts shown in Table 1 exclude below cut-off (<0.58% NiEq%) selvedges at the top and bottom of the mineralised intercept.
Drilling has been completed exclusively by diamond drilling, with holes collared in PQ diameter to drill through the highly weathered quartzite, then downsizing to HQ diameter down to 300–600 m, and then typically finishing in NQ diameter for drilling into the deeper parts.
Core recovery for the recent drilling has resulted in an average of 98.7% recovery overall. A projected long section, showing the full drillhole traces of the recent drilling, together with the drillhole intercepts of the pre-2021 drilling where Ni%>0.5 and historical mineralisation interpretations, is shown in Figure 1. An example cross section is shown in Figure 2.
Drillhole collar locations are surveyed in UTM ARC 1960 grid using differential GPS in units of metres. Drillhole collar details are shown in Table 2. The drillhole data is subsequently converted to the MG09 grid by subtracting 200,000 from the easting and 9,600,000 from the northing and adding 10,000 to the elevation.
“As we conduct detailed studies to optimise Kabanga’s annual output, we are also encouraged that the extensive infill drilling we are undertaking has increased our understanding of the project. The intersections reflected in the drilling results show the quality of the Kabanga Project and the thickness of this world-class orebody.” Chris Showalter, Lifezone Metals’ CEO, said. “The extensive work underway on the Definitive Feasibility Study for Kabanga is key to optimising development of the Kabanga mine and Kahama refinery to realise its true value and benefit all shareholders.”
