Kabwe Drilling hits another High-Grade zone

Shuka Minerals Plc (AIM/AltX: SKA), an African focused mine operator and developer, is pleased to announce that, further to the announcement on 3 June 2026, it has successfully completed the third drill hole ("KBDD03") at the No. 2 ore body at the Kabwe Zinc Mine ("Kabwe Project").

Drilling

The third diamond drill hole was planned at 65 degrees at a bearing of 125 degrees and was designed to intersect the ore body 30 metres ("m") to the east of the KBDD01 intersection at a depth of approximately 250m. The Company has commenced a fourth hole to intersect the orebody in the western area of the extended ore body.

The actual readings from a down hole gyroscope survey revealed the hole was 240m deep, with a final azimuth of 123.66 degrees and a dip of 65.49 degrees. All of these survey readings are vital in order to accurately map the trajectory of the hole and therefore the mineralised zones in a 3D model.

As previously announced, the Behre Dolbear 2023 NI 43-101 report indicates that the No. 2 ore body has 3.1MT of ore remaining at grades of 11.4% zinc and 1.7% lead plus silver and vanadium oxide.

Results

KBDD03 returned 29.58% zinc over 19.0m from 221.10m to 240.10m (down hole), based on an arithmetic average of 62 individual portable XRF readings at 3 readings per metre of whole core.

Individual readings over the entire interval ranged from 1.0% - 53.0% zinc with better point grades, averaging 40.09% zinc in the uppermost 9m of the orebody.

Mineralisation is typically associated with a weakly brecciated to semi-massive haematitic ironstone mixed with mostly zinc silicate (probably willemite) and lesser zinc carbonate minerals. The footwall comprises moderately jointed and fractured massive dolomite with hematite stringers and fracture-coatings that are believed to be the main hosts to zinc mineralisation.

The GeoQuest geological team are on site with the Company's CEO, Richard Lloyd, who is overseeing the initial (2,000m) phase of drilling. Drilling is being undertaken by Ox Drilling Limited, a contractor with 21 years established operating experience in Zambia.

The Company will provide further updates as drilling advances.

Shuka Minerals CEO, Richard Lloyd, commented:

"The follow up holes of our campaign continue to deliver excellent Zn grades, with every hole and intersection we are learning more and more about the orebody. It is also extremely encouraging to continue to see much higher grades and over significant widths versus the previously reported N 43 101 resource. The upcoming drill holes will look to prove the ore body extending laterally and at depth."
