SHUKA MINERALS PLC - Kabwe Drilling (KBDD01-05) ALS Laboratories Confirm Scale and High-Grade Drilling Results at Pit 2 of the Kabwe Project

Full analysis

What this filing means

ALS laboratory confirmation for all five holes at Pit 2 of the Kabwe Zinc Mine confirms high-grade mineralisation: KBDD03 returned a standout 19.95m at 29.07% Zn, and peak grades across the campaign reached 48.5% Zn. The Board has reaffirmed its target of at least 50% resource growth. However, the August 2026 drilling disclosures — including a 70% Zn peak grade — had already set the thesis the market was trading, so these confirmatory ALS results arrive after meaningful prior positioning.

Shuka drilled five holes at Kabwe and the lab results are back. The grades are very high — one hole hit nearly 30% zinc over 20 metres. The company says it expects to grow its resource estimate by at least half. That is material for a small miner. But the August announcement of a 70% zinc peak grade had already pointed in the same direction, so this confirmation reinforces rather than surprises.

Bull case

  • KBDD03 returned 19.95m @29.07% Zn from 221.0m — a standout intersection well above the historic No 2 orebody average of 11.5% Zn cited in the Behre Dolbear resource.
  • All five holes returned peak zinc grades between 25.5% and 48.5% Zn, exceeding the historic block average and confirming scale of high-grade mineralisation at Pit 2.
  • Applying the more realistic 5% Zn cut-off materially widens reported intersections versus the historic 10% cut-off (e.g. KBDD01 widens from 12.29m to 21.34m), expanding the mineralised envelope and supporting resource growth.
  • The Board has explicitly targeted at least a 50% increase on the historical resource at Pit 2, citing these ALS-confirmed results as the basis for that guidance.

Bear case

  • The 50% resource growth target is Board guidance based on drilling confidence — the filing contains no compliant NI 43-101 or JORC mineral resource estimate.
  • Silver, vanadium, germanium, and gallium assays remain outstanding — material byproduct revenue streams the CEO calls significant are unquantified in this filing.
  • The Behre Dolbear 2023 NI 43-101 report is limited to 300m depth — the filing does not confirm whether current drilling extends the mineralised envelope below this limit or retests existing mineralisation.

SENS-AI conclusion

ALS-confirmed high-grade intersections that support the Board's stated resource-growth aspiration: KBDD03 at 19.95m @29.07% Zn and peak grades of 48.5% Zn are material data points. The August 2026 drilling disclosures had already established the high-grade thesis the market was trading, so this confirmation of ALS assay data — against a prior run-up — provides limited incremental information. The grades are real; the resource conclusion remains prospective. So what: the drilling thesis is confirmed, but the market still needs the updated mineral resource estimate and the outstanding silver, vanadium, germanium and gallium assays to size whether the 50% growth target is achievable in a compliant statement.

The updated NI 43-101 or JORC-compliant mineral resource estimate is the next disclosure that will test whether the 50% growth target is achievable, and the outstanding byproduct assays will determine whether the resource carries material credits.

Evidence from the filing

  • KBDD03 returned 19.95m @29.07% Zn from 221.0m — a standout intersection well above the historic No 2 orebody average of 11.5% Zn cited in the Behre Dolbear resource.

    “19.95m @29.07% Zn from 221.0m to 240.9m”

  • All five holes returned peak zinc grades between 25.5% and 48.5% Zn, exceeding the historic block average and confirming scale of high-grade mineralisation at Pit 2.

    “Maximum zinc grade lab results returned for the Pit 2 drilling campaign were as follows and compare favourably with the pXRF results previously announced: KBDD01: 38.4% Zn; KBDD02: 31.9% Zn; KBDD03: 48.5% Zn; KBDD04: 25.5% Zn; KBDD05: 48.5% Zn”

  • The Board has explicitly targeted at least a 50% increase on the historical resource at Pit 2, citing these ALS-confirmed results as the basis for that guidance.

    “These results give the Board confidence in a significantly increased mineral resource and supports the Company's statement that we are looking to increase the historical resource at Pit 2 by at least 50%.”

  • The historic block average of 11.5% Zn and the historic peak grades in the 20-22% range provide the comparative context the CEO cited for current results.

    “with the highest grades reported being 20-22% Zn”

  • The Behre Dolbear 2023 NI 43-101 report is limited to 300m depth — the filing does not confirm whether current drilling extends the mineralised envelope below this limit or retests existing mineralisation.

    “The Behre Dolbear 2023 NI 43-101 report indicates that the No 2 orebody contains 1.958 million tonnes of indicated and inferred resource at grades of 12% Zn and 2% Pb down to 300m depth, out of a total estimated remaining tonnage of 2.956MT at 11.5% Zn and 1.7% Pb to 600m depth.”

  • Silver, vanadium, germanium, and gallium assays remain outstanding — material byproduct revenue streams the CEO calls significant are unquantified in this filing.

    “Additional analysis is still being undertaken by ALS for silver, vanadium, germanium and gallium with those results expected in due course.”
