Ntorya Operations Update

Aminex, the oil and gas exploration and development company focused on Tanzania, is pleased to announce the following:

· During meetings in Tanzania this week between the Tanzania Petroleum Development Corporation (TPDC), ARA Petroleum Tanzania (APT) and Aminex, the TPDC provided the following update on the pipeline from the Ntorya gas field to the Madimba gas processing plant (the Pipeline):

o  the Pipeline contractors have begun the procurement process for the acquisition of all necessary pipe and equipment;

o  mobilisation of construction equipment to the site will begin in September 2025; and

o  groundwork and pipelaying will commence in January 2026 with completion by July 2026.

· The processing and storage of condensate was also discussed by the parties during such meetings.

· The Petroleum Upstream Regulatory Authority (PURA) has approved the tender strategy for contracting a rig to drill the Chikumbi-1 well and perform a workover on the Ntorya-1 well, along with all related services. APT has informed Aminex that it will be requesting expressions of interest from the relevant service contractors next week.

Charles Santos, Executive Chairman of Aminex, commented:

"Our discussions with the TPDC and the operator have been extremely fruitful, and we are delighted that activity on the Pipeline is proceeding as planned. We are also pleased that discussions on the processing of condensate volumes in the field are progressing, and we believe these will provide additional value to the project. Finally, we are pleased that PURA has approved the tender strategy, allowing APT to begin the tender process. These developments demonstrate again the Government of Tanzania's strong commitment to this project which will deliver large volumes of gas supplies to help alleviate energy poverty, boost industrial development and fuel Tanzania's economic growth.

We are grateful to the TPDC, PURA and APT for their professionalism and commitment in progressing the project and look forward to updating shareholders further as our project advances."

Notes to Editors:

The Ntorya Development Licence area lies adjacent to a region containing supergiant world-class LNG projects, extending from offshore Tanzania into Mozambique waters to the south. The JV partners intend to produce Ntorya gas into the growing domestic gas market, helping to alleviate energy poverty and boost the energy transition in Tanzania.

Aminex, with a 25% non-operated interest, is carried throughout the ongoing work programme to a maximum gross capital expenditure of $140 million ($35 million net to Aminex). The carry is expected to see the Company through to the commencement of commercial gas production from the Ntorya field at zero cost to the Company.
