Talonx Eyes District-Scale Copper Upside Beyond Its 27Mt Botswana Base
Key Takeaways
- Copper was entirely excluded from Kihabe's 2022 Mineral Resource estimates, meaning any copper discovery is pure upside on top of the existing 27.0Mt zinc-lead-silver resource containing 385,000t zinc, 186,000t lead, and 6.44Moz silver.
- Historical drilling has already confirmed copper mineralisation across an 800-metre strike in the northeastern sector of Kihabe, with intercepts including 7m at 1.04% Cu and 18m at 0.43% Cu.
- The 20km northeast-trending Kihabala Trend — defined by regional zinc-lead geochemistry — has never been tested for copper, representing a district-scale exploration corridor beyond the known deposits.
- Talonx is pursuing two copper discovery models simultaneously: sediment-hosted copper (Tschudi-style) and carbonate-replacement and structurally controlled copper (Kombat/Tsumeb-style) across 1,000km² of tenure in Botswana's underexplored Damara Belt extension.
- The work programme is at the pre-drill stage — rock-chip sampling, geological mapping, and geophysics are underway — with drill target definition the key catalyst to watch under a prospecting licence renewed to 31 December 2026.
Talonx targets district-scale copper opportunity at Kihabe Project
Talonx Resources (ASX: TXR) has identified a district-scale copper and base-metal exploration opportunity at its approximately 1,000km² Kihabe Project in north-west Botswana. The project sits within Botswana’s substantially underexplored northeastern extension of the Damara Orogenic Belt, the same geological system that hosts major copper and polymetallic deposits in neighbouring Namibia.
Critically for investors, copper was not included in the 2022 Mineral Resource estimates for the project. That means any copper discovery potential represents upside sitting entirely outside the already-established zinc-lead-silver resource base, which currently stands at 27.0Mt (Indicated and Inferred), containing approximately 385,000t zinc, 186,000t lead, and 6.44Moz silver across the Kihabe and Nxuu deposits.

Historical drilling confirms copper at Kihabe
Historical drilling has already returned copper intersections across an approximately 800m strike extent in the northeastern sector of the Kihabe deposit. Copper occurs in association with the broader polymetallic mineralisation in the northeastern sector of the Kihabe deposit.
Selected historical intersections (all downhole lengths; true widths are not known) include:
- KIH011: 7m at 1.04% Cu from 71m
- KDD140: 6.5m at 0.67% Cu from 91m
- KRC052: 18m at 0.43% Cu from 122m (including 2m at 0.75% Cu and 3m at 0.76% Cu)
- KDD114: 11m at 0.37% Cu from 106m (including 1m at 1.44% Cu from 116m)
- KRC076: 20m at 0.28% Cu from 17m (including 2m at 0.71% Cu from 23m)
These are selected historical results illustrating copper mineralisation at Kihabe. They do not establish a continuous copper body across the 800m corridor, and copper has not been estimated as a Mineral Resource.
The established zinc-lead-silver resource base provides important context for the base-metal fertility of the project’s sedimentary succession:
| Deposit | Classification | Total (Mt) | Grade (Zn / Pb / Ag) | Contained Metal |
|---|---|---|---|---|
| Kihabe | 11.7Mt Indicated; 9.3Mt Inferred | 21.0 | 1.5% Zn, 0.7% Pb, 8.1g/t Ag | 321kt Zn; 154kt Pb; 5.40Moz Ag |
| Nxuu | 2.7Mt Indicated; 3.2Mt Inferred | 6.0 | 1.1% Zn, 0.5% Pb, 5.4g/t Ag | 64kt Zn; 32kt Pb; 1.04Moz Ag |
| Combined | Indicated and Inferred | 27.0 | 1.41% Zn, 0.66% Pb, 7.5g/t Ag | 385kt Zn; 186kt Pb; 6.44Moz Ag |
Understanding the Damara Belt — why the geology matters for investors
The Damara Orogenic Belt is a Neoproterozoic geological system that stretches across southern Africa. What makes it relevant here is its track record of hosting substantial copper and polymetallic deposits, particularly in Namibia. Botswana’s northeastern extension of this belt — where Kihabe sits — remains largely underexplored.
A proven copper address in the region
Several deposits in the broader Damara Belt provide useful geological reference points. Tschudi hosts sediment-hosted copper mineralisation within sandstone and related sedimentary units. Tsumeb contains copper-lead-zinc mineralisation within a pipe-like structure hosted in carbonate rocks. Kombat features copper-lead-silver mineralisation associated with carbonate replacement, fractures, and breccias within dolomite.
More recent examples include Midas Minerals’ T13 copper-silver deposit (high-grade, structurally controlled) and Kaoko Metals’ Chalkos project (sediment-hosted copper-silver) in the adjoining Kaoko Belt. These regional deposits demonstrate that the broader geological system is capable of hosting significant copper mineralisation in a range of settings. They provide geological context only and should not be taken as evidence of equivalent grades, dimensions, or economic potential at Kihabe.
Two paths to copper discovery at Kihabe
The Kihabe Project’s succession of arenite, quartz wacke, and dolomite supports two copper exploration models that Talonx is now pursuing:
- Sediment-hosted copper: Mineralisation associated with favourable sedimentary horizons and changes in rock composition or chemistry, of the style seen at Tschudi.
- Carbonate-replacement and structurally controlled copper: Mineralisation within reactive dolomite, fractures, breccias, and structural intersections — settings capable of concentrating copper-bearing fluids into discrete, potentially higher-grade bodies.
The second model is of particular interest because replacement processes within structurally prepared dolomite have the potential to concentrate mineralisation into higher-grade shoots and veins, as demonstrated at Kombat and Tsumeb in Namibia.

Next steps — defining drill targets across the project
Talonx has commenced a staged assessment focused on defining priority copper and base-metal drill targets across the project’s underexplored sedimentary and carbonate succession. The initial work programme is focused on four activities:
- Targeted rock-chip and conventional soil sampling to identify copper and associated base-metal anomalism beyond the known deposits
- Geological mapping of favourable sedimentary horizons and structural settings with potential to host sediment-hosted copper and higher-grade replacement mineralisation
- Targeted geophysics to investigate prospective positions beneath Kalahari cover
- Integration of geochemical results, geological mapping, and historical drilling to define and rank priority targets for follow-up drilling
Beyond the known resource areas, regional geochemistry outlines an approximately 20km northeast-trending zinc-lead anomalous corridor known as the Kihabala Trend. This zinc-lead geochemical feature highlights the district-scale exploration opportunity; copper potential along this corridor remains to be tested.
The project is held under Prospecting Licence PL43/2016, renewed to 31 December 2026. For investors watching the Talonx story, the key point is straightforward: copper was excluded entirely from the 2022 resource estimates, and the work programme now under way is the catalyst to watch as the company works towards defining drill targets across what it describes as a substantially underexplored geological setting.
