ALS Laboratories Confirm Scale and High-Grade Drilling Results at Pit 2 of the Kabwe Project
Shuka Minerals Plc (AIM/AltX: SKA), an African focused mine operator and developer, is pleased to announce that, further to the announcement on 26 August 2026, it has received laboratory results from ALS Labs for all 5 holes drilled in the "PIT 2" area at the Kabwe Zinc Mine ("Kabwe Project").
Holes KBDD01 through KBDD05 were drilled as part of the 1st phase drilling campaign recently concluded by Ox Drilling. Samples were delivered to ALS Labs, Ndola, where they were prepared and sent to the ALS laboratory in Johannesburg where they were tested by ICP Sodium Peroxide Infusion (ME-ICP 81) for Zn, Pb and Cu.
The table below summarises the results received and the Zinc ("Zn") intersections derived at 2 different cut off grades. A 10% Zn cut-off grade was historically used, however, the Board considers that, given current analysis and commodity prices, utilisation of a 5% Zn cut-off grade is more appropriate, which significantly increases the historically reported and current resources. KBDD05 holes can even sustain a 2% cut off grade due to the very high grade zones within. The final mining methods would determine these cut offs:

A strict QAQC Regime representing combined 14.5% Insertion frequency of CRM's, Blanks and Duplicates was followed and adhered to.
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 Behre Dolbear 2023 NI 43-101 report indicates that the No 2 orebody contains 1.958 million tonnes ("MT") 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. Significant silver and vanadium oxide also exist. Additional analysis is still being undertaken by ALS for silver, vanadium, germanium and gallium with those results expected in due course.
Shuka Minerals CEO, Richard Lloyd, commented:
"The lab results returned confirm extremely high grades in the Pit 2 area and well above those grades previously reported in the historic blocks where averages were reported at 11.5% Zn and 1.7%Pb with the highest grades reported being 20-22% Zn. This may be due to the improvement in laboratory testing capabilities since the historic resource.
"The lab results compare favourably to the spot pXRF results. We have compared readings with 2 cut off grades, a historic 10% Zn cut-off and a more realistic 5% Zn cut-off, the results clearly show much wider intersections at the more realistic cut-offs, and with the very high grades you would be able to withstand increased internal dilution once mining commences.
"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%."
