Shuka Minerals Plc (AIM/AltX: SKA), an African focused mine operator and developer, is pleased to announce that, further to its announcement of 19 March 2025, it has received the assay results for certain samples from the Kabwe Zinc Mine ("Kabwe Mine") which had previously exceeded the upper detection limits of the initial testing.
Ten surface samples collected from outcrop and artisanal workings were initially analysed by ALS (Johannesburg), using 48-element ICP analysis. Certain samples exceeded the upper detection limits for zinc and lead under that method. Eight lead samples exceeding the detection limit (>1% Pb) were re-analysed at ALS (Johannesburg) using four-acid ICP-AES. Two zinc samples exceeding the detection limit (>30% Zn) were re-analysed at ALS (Vancouver) using titration methods.
The following results were received on 25 February 2026 from the respective laboratories:
| Sample | Zinc (Zn) % | Lead (Pb) % |
|---|---|---|
| KAB 25 001 | 1.235 | |
| KAB 25 002 | 6.10 | |
| KAB 25 003 | 3.31 | |
| KAB 25 005 | 3.88 | |
| KAB 25 006 | 42.89 | 1.345 |
| KAB 25 007 | 1.385 | |
| KAB 25 008 | 1.180 | |
| KAB 25 009 | 34.66 | |
| KAB 25 010 | 1.320 |
The results continue to demonstrate consistently high zinc and lead grades at surface, with zinc values reaching up to 42.89% and lead values up to 6.10%, supporting the earlier results provided by ALS.
These grades compare favourably with historical mining averages and confirm the presence of substantial high-grade material at surface.
The previously announced 48 element sample results from ALS returned the following results:
| Sample | Zn (%) | Pb (%) | Ag (ppm) | Ce (ppm) | Cs (ppm) | Ga (ppm) | Mn (ppm) | Mo (ppm) | Rb (ppm) | Sn (ppm) | V (ppm) | Y (ppm) |

CEO Richard Lloyd commented: "It is encouraging to realise further high-grade laboratory confirmed results and at surface. We will update the market further when we receive lab results from the current samples which have already been submitted to ALS in Ndola, Zambia."
