Ntorya Operations Update

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

· At the end of last week, the Tanzania Petroleum Development Corporation (TPDC) formally notified the operator of the Ntorya development (ARA Petroleum Tanzania Limited (APT)) that construction of the pipeline from the Ntorya gas field to the Madimba gas processing plant (the Pipeline) shall commence in July 2025 and is scheduled to be completed and commissioned by the end of July 2026. The Ntorya-2 well will provide gas once the Pipeline is commissioned.

· Earlier this week, APT presented a tender strategy to the Petroleum Upstream Regulatory Authority (PURA) for contracting a rig to drill the Chikumbi-1 well and perform a workover on the Ntorya-1 well, along with all related services. PURA requested this strategy to expedite the tendering process. Once APT receives approval from PURA, it will immediately issue the rig tender and tenders for other necessary services, expecting to do so no later than mid-August 2025.

Charles Santos, Executive Chairman of Aminex commented:

"We are delighted that work on the pipeline will commence this month, marking the start of the construction phase of the Ntorya Gas Development. With a plan to complete the Pipeline by July 2026 and expectation of starting a rig tender process very soon, the project is well on its way to producing first gas next year.

We are grateful to the TPDC, PURA and other agencies, which have backed the Government of Tanzania's strong commitment to our project with their hard work. And we thank APT as the operator for managing the dynamic work streams to reach this milestone.

As the discoverer of the Ntorya Gas Field and founding partner in the development, we have long believed the project will be a gamechanger for Tanzania's energy landscape. Gas from the first phase of development will be staying in Tanzania to help power homes, boost industrial development and the regional economy and replace dirtier fuels such as coal and charcoal. This has long been our vision and now we are very excited to be so much closer to realising that vision."

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.
