Charles Santos, Executive Chairman of Aminex, commented:

"I'm very pleased to say that the Ntorya gas development is progressing well and on track for first gas next year. Clearly, 2026 will mark the start of an exciting new chapter for Aminex and the beginning of a new era for Tanzania's energy security and energy transition.

I have just spent a few highly productive days in Dar es Salaam, meeting APT as well as government and energy officials to discuss our plans in Tanzania for the next year. Tanzania is on the cusp of a gas revival which will fuel industrial and economic development while helping to improve Tanzanians' living standards. We're very excited to be part of that story and look forward to continuing our close collaboration with the Ministry of Energy, the Tanzania Petroleum Development Corporation (TPDC), the Petroleum Upstream Regulatory Authority (PURA) and of course Ntorya's operator, APT."

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.
