Lifezone Metals Reports Completion of Tembo Zone Infill Drilling at the Kabanga Nickel Project with 41 m Intersect at 2.07% Ni, including 16.4 m at 2.77% Ni

New York (United States), Dar es Salaam (Tanzania), Aug. 31, 2023 (GLOBE NEWSWIRE) -- Lifezone Metals Limited (“Lifezone Metals” or the “Company”) (NYSE: LZM), a modern metals company creating value across the battery metals supply chain from mine to metals production and recycling, is pleased to announce an update on its resource definition drilling programme at its Kabanga Nickel project (“Kabanga”) in North-West Tanzania. The Kabanga Nickel project is owned jointly by Lifezone Metals, through its subsidiary Kabanga Nickel Ltd (“KNL”) and BHP Billiton (UK) DDS Limited (“BHPB”), forming Tembo Nickel Corporation Limited (“TNCL”), the operating entity, together with the Government of Tanzania.

Infill and extensional drilling at the Tembo Zone, which will support an upcoming Mineral Resource estimate (“MRE”) and the Definitive Feasibility Study (“DFS”), was successfully completed in July 2023 using four diamond drill rigs on average. Tembo Zone drilling completed from 2021 through July 2023 (see Figure 1) by TNCL comprised of 49 holes, resulting in a total of 23,748 m of diamond drill core available for geological logging and sampling. A further nine holes for a total of 2,596 m were drilled at the Tembo Zone for metallurgical sampling, plus six geotechnical holes (2,312 m) to support the ongoing DFS. Drill core was logged to capture geological and geotechnical features in the on-site drillhole database, and samples were submitted for analysis to SGS’s laboratory in Mwanza, Tanzania.

Highlights from Tembo Zone drilling includes:

• Hole KL22-10 intersected 41 m at 2.07% Ni, 0.39% Cu, and 0.16% Co, (2.67% NiEq23[1]), including 16.4 m at 2.77% Ni, 0.45% Cu, and 0.23% Co, (3.59% NiEq23),
  (see Figure 4 and Figure 5).
• Hole KL22-12 intersected 39.6 m at 2.04% Ni, 0.37% Cu, and 0.13% Co, (2.55% NiEq23), including 19.9 m at 2.83% Ni, 0.44% Cu, and 0.19% Co, (3.53% NiEq23),
  (see Figure 6 and Figure 7); and
• Hole KL21-01 intersected 29.7 m at 1.94% Ni, 0.29% Cu, and 0.16% Co, (2.51% NiEq23), including 17.0 m at 2.42% Ni, 0.38% Cu, and 0.21% Co, (3.15% NiEq23).

Lifezone Metals’ CEO, Chris Showalter said: “Even after years of exploration and >620 km of drilling to date, the Kabanga orebody continues to showcase its quality differential with world-class nickel grades. The most recent infill drilling at the Tembo Zone ensures we can progress towards an updated Mineral Resource estimate, which is crucial for the Definitive Feasibility Study and ultimately support the mine plan.”

Infill drilling continues at the North Zone, with five diamond drill rigs in operation since late‑June 2023. Three holes have since been completed and seven are underway (two currently pre-collared only) for a total of 6,626 m of drill core (to 18 August 2023).

Recent highlights from the North Zone infill drilling includes:

• Hole KN22-03 intersected 52.0 m at 2.37% Ni, 0.25% Cu, and 0.14% Co, (2.85% NiEq23), including 39.8 m at 3.03% Ni, 0.32% Cu, and 0.18% Co, (3.65% NiEq23); and
• Hole KN22-01A intersected 27.7 m at 2.56% Ni, 0.32% Cu, and 0.22% Co, (3.29% NiEq23).

Gerick Mouton, COO added: “We are working well on the ground with the rigs and local laboratories, and I am pleased to see this package of work for the Tembo Zone infill drilling campaign come together. With these intersects and grades on both Tembo and North Zones it undoubtably underscores Kabanga’s immense quality. Other ongoing drilling activities, undertaken by four additional rigs, relate to surface and mine geotechnical and hydrological drilling supporting the DFS designs and water balance.”

Since December 2021, TNCL has completed 82 holes for more than 35 km of diamond core drilling at Tembo, North, and Safari (to 18 August 2023).

All field work since December 2021 has been conducted on Special Mining Licence ‘SML 651 / 2021’.

The current North Zone drilling programme is expected to be complete by mid-September 2023, after which focus will shift to a new drilling programme that has been developed for the currently untested zone between Tembo North and Safari, known as the Safari Link programme.

Drilling in Tembo North and Safari shows that the shallow mineralisation trend is open along strike. The Safari Link drilling programme aims to test for the presence of Tembo-style mineralisation, as signalled by airborne EM/magnetics and ground EM coverage, which shows no significant gaps along strike to the north-east of Tembo.

The Safari Link drilling programme, which covers a strike length of approximately 1.5 km and comprises 62 diamond core drillholes for approximately 34 km of drilling, has been approved by TNCL. This programme (see Figure 3) is expected to require approximately six months to complete with six diamond drill rigs and will proceed in three phases: the first of which will test the presence of mineralisation in the Safari Link Zone, and the subsequent phases will infill as required to increase confidence in the characteristics and volume of any mineralisation that is identified to enable its incorporation into subsequent geological modelling.

Additional Information: Kabanga Geological History and MRE Overview

Geology Overview

The Kabanga nickel deposit is located within the East African Nickel Belt (EANB), which extends approximately 1,500 km along a north-east trend from Zambia to Uganda.

The northern and central sections of the EANB are characterised by a thick package of Paleoproterozoic to Mesoproterozoic metasedimentary rocks, known as the Karagwe–Ankole Belt (KAB), within which occurs a suite of broadly coeval, igneous intrusions that correspond to the Kibaran tectonothermal event (1,350–1,400 Ma).

At the project area, the metasediments, which comprise pelites, sandstones, and quartzites, are overturned steeply dipping (70° to 80° to the west), with a north–north-east strike orientation (025°) from Main to North, changing to a north-east strike orientation (055°) from North to Safari (see Figure 9).

The potentially economic nickel-bearing massive sulfides are hosted within igneous chonoliths that are concentrically zoned with a gabbronorite margin and an ultramafic cumulate core. The project comprises six distinct sulfide mineralisation zones, namely (from south-west to north-east) Main, MNB, Kima, North, Tembo, and Safari, which occur over a strike length exceeding 7.5 km.

Kabanga sulfide mineralisation occurs both as:

• Disseminated to net textured interstitial sulfides within the cumulate core zone of the chonoliths, as well as externally; and
• Massive and semi-massive sulfide bodies along the side margins of the chonoliths.

The massive sulfides, which comprise dominantly pyrrhotite, with trace-to-15% pentlandite, account for the majority of the Mineral Resource estimates.

Exploration/Drilling/History Overview

Exploration at Kabanga has been undertaken in several different phases spanning over 45 years, with more than 621 km of drilling having been completed in total over that time (see Table 2), less than 5% of which was on regional targets. The North and Tembo mineralised zones are the most densely drilled of all the mineralised zones identified to date.

The first drilling programme was undertaken by the United Nations Development Program (UNDP) between 1976 and 1979. Following a ten-year moratorium on foreign company exploration, Sutton Resources (Sutton) entered into several different joint ventures (JV) to explore between 1988–1999, after which Barrick Gold took over control of the project through the purchase of Sutton and progressed through several more drilling programmes independently and within JVs with Glencore. Several studies were completed from 2003 onwards, including scoping and prefeasibility studies, followed by an unpublished draft feasibility study undertaken by the Glencore–Barrick Gold JV in 2014. By the end of 2014, approximately 586 km of diamond drilling had been completed.

In 2019, Kabanga Nickel Ltd (KNL) acquired the project. KNL is jointly owned by LHL (83%) through its 100% entity, Lifezone Limited, with the remaining 17% directly owned by BHP Billiton (UK) DDS Limited (BHPB). KNL owns 84% of the project, with the remaining 16% held by the Government of Tanzania under the terms of a framework agreement.

Since December 2021, KNL has completed 82 holes for more than 35 km of diamond core drilling at Tembo, North, and Safari (up to 18 August 2023) (see Table 2).

Table 2 Holes Completed Since Project First Discovered (to 18 August 2023)

All field work since December 2021 has been conducted on Special Mining Licence ‘SML 651 / 2021’ (see Figure 10 and Figure 11).

Permitting Overview

In Tanzania, minerals and natural resources are state owned and the rights to explore and mine minerals and to use natural resources are obtained from regulatory bodies defined in legislation that have a defined duration and are conditioned.

Mineral rights are held in the form of prospecting licences and mining licences. There are several types of prospecting licences and mining licences, depending on the nature of the minerals being mined and the size of the mine. A Special Mining Licence (SML) is the type of licence required for large scale mining operations (‘large scale’ being defined as those requiring a capital investment not less than US$100 million), and so this is the type of licence required for Kabanga.

Mineral Resources Overview

Ordinary kriged resource estimates were completed in 2008 as part of the Glencore–Barrick Gold JV prefeasibility study. A thorough independent technical audit of the database, QA/QC, and the resource estimates was completed in 2009. The final resource estimate updates were completed in 2010 following an infill drilling campaign. The 2010 estimates form the basis of the Glencore–Barrick Gold JV 2014 draft feasibility study (unpublished).

Check models were completed by KNL for North and Tembo in 2021 using the same drillhole database as the 2010 estimates with a different interpretation and modelling approach. The 2010 and 2021 models were validated and compared visually and statistically for all grade elements estimated and for density.

In March 2023, the current Mineral Resource estimates (see Table 3) were published in a Technical Report Summary under US SEC Regulation S‑K subpart 1300 rules for Property Disclosures for Mining Registrants (S‑K 1300) (effective date 15 February 2023). This is the first time the Kabanga Mineral Resource estimates have been reported under S‑K 1300 guidelines.

As the Kabanga North and Tembo zones contain multi element mineralisation, a nickel equivalent (NiEq) formula updated for current metal prices, costs and other modifying factors has been used for reporting from the Mineral Resource.

The 2023 nickel equivalent (NiEq23) formula is as follows:

NiEq23 (%) = Ni% + Cu% x 0.411 + Co% x 2.765

The 2023 NiEq cut‑off grade is 0.58% NiEq.

Metal price assumptions used for cut‑off grade determination were $9.50/lb for nickel, $4.00/lb for copper, and $26.00/lb for cobalt.

The Initial Assessment assumes an underground mining rate of 2.2 Mtpa. The mining method is underground stoping with backfill, and the extracted mineralised material will feed into an on‑site concentrator. Concentrate is assumed to be transported to an off‑site hydrometallurgical processing facility to produce final nickel, copper, and cobalt metal, with transport of the final metal to Dar es Salaam and export to markets for sale.

A cash flow analysis was not performed for the Project. The Initial Assessment has been prepared to demonstrate reasonable prospects of economic extraction, not the economic viability of the Mineral Resource estimates. The Initial Assessment is preliminary in nature, it includes Inferred Mineral Resources that are considered too speculative geologically to have modifying factors applied to them that would enable them to be categorised as Mineral Reserves, and there is no certainty that this economic assessment will be realised.

Table 3   Kabanga Mineral Resource Estimates as at 15 February 2023
Based on Metal Prices: $9.50/lb Nickel, $4.00/lb Copper, and $26.00/lb Cobalt

1. Mineral Resources are reported exclusive of Mineral Reserves. There are no Mineral Reserves to report.
2. Mineral Resources are reported showing only the LHL attributable tonnage portion, which is 69.713% of the total.
3. Cut‑off uses the NiEq23 using a nickel price of $9.50/lb, copper price of $4.00/lb, and cobalt price of $26.00/lb with allowances for recoveries, payability, deductions, transport, and royalties.
   NiEq23% = Ni% + Cu% x 0. 411 + Co% x 2.765.
4. The point of reference for Mineral Resources is the point of feed into a processing facility.
5. All Mineral Resources in the 2023MRE were assessed for reasonable prospects for eventual economic extraction by reporting only material above a cut‑off grade of 0.58% NiEq23.
6. Totals may vary due to rounding.
