Drilling commences on the Ongombo Project

African Pioneer Plc (“AFP”), the exploration and resource development company is pleased to announce that drilling as part of the mine development programme has commenced on the Ongombo Project in Namibia under the terms of the conditional financing and technical services agreement (the “Definitive Agreement”) signed between the Company and Hong Kong Xinhai Mining Services Limited (“Xinhai”) and announced on 30 July 2026.

Highlights

The progamme has commenced with one drill rig to ensure that the technical personnel required to oversee and manage the estimated volume of core to be generated are properly trained. In conjunction planning has started for the construction of an onsite facility for core to be received, logged, cut and sampled before it is tested and to provide a secure core facility for the long term.

The programme is for 119 holes for approximately 7,000 metres will last for several months with an additional period thereafter for the receipt of final assays.

The Ongombo project which is 85% owned already has a 29Mt @ 1.1% CuEq JORC (2012) Mineral Resource Estimate defined by external resource consultants for the Ongombo Project (see 16 May 2023 announcement for further details)

The drill programme has multiple objectives which include;

Open pit Resource extensions delineated by external engineering consultants validating the estimated potential of 3 to 4 years of open pit mining

explore the potential up-dip extensions of known mineralised bodies at the neighbouring Ongeama project offers scope for additional early years open pit feed

provide additional data to inform mine design and long-term planning of underground development together with geotechnical assessment at both Ongombo and Ongeama

provide additional grade and mineralised width data for parts of the East – Ost shoots where drill density can be improved and historically (1980’s) gold assays were not completed. The East – Ost shoots are notably thicker in some parts of the two bodies potentially offering more substantial tonnage subject to ongoing infill drilling

developing a single Mineral Resource for mining and processing purposes from the two deposits

Colin Bird, Chairman of African Pioneer, commented: “I am pleased to be able to confirm that work is underway that will lead to the development of a new mining operation at Ongombo – Ongeama. Our partners at Xinhai have been working closely with our Namibian-based team and we are providing the in-country technical skills required to manage the drilling programme including logging, sampling and sample custody for certified assays. We will keep shareholders updated with progress as we increase the number of drill rigs on-site to fast-track the programme”.

Glossary

An ‘Indicated Mineral Resource’ is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.

An ‘Inferred Mineral Resource’ is that part of a Mineral Resource for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.
