Ntorya Operations Update

Aminex is pleased to provide the following operational update from ARA Petroleum Tanzania Limited ("APT"), operator of the Ruvuma PSA, on the Ntorya gas development.

Ntorya-3 (“NT-3”)

As previously announced, the contract for the supply of the drilling rig (“the Rig”) has been signed. The Rig has been released by Maurel & Prom and arrival at the NT-3 site is scheduled for mid-December 2026. Spudding of the well is anticipated in late-December 2026, following rig-up, commissioning and acceptance, and mobilisation of the required drilling services. The Rig has been contracted to drill NT-3, with an option to (a) carry out a workover on NT-1 or drill a separate well and (b) drill two additional wells.

Civil works to construct the NT-3 well pad and access roads are approximately 60% and 80% complete, respectively, with completion and site handover targeted for 15 December 2026. Rig base-camp preparation commenced on 20 September 2026, with handover targeted for later this month.

Ntorya-2 (“NT-2”)

Wellhead maintenance operations on NT-2 have recently been completed, with no major findings. The operator is awaiting delivery of the necessary equipment to commence bridge-plug removal operations, now scheduled for late November 2026. Subject to contract finalisation and the timely mobilisation of the gas processing unit, testing of NT-2 is scheduled to commence in December 2026, followed by production into the Ntorya-Madimba pipeline in late-December 2026.

Ntorya-1 (“NT-1”)

Wellhead maintenance and slickline operations on NT-1 have been delayed pending delivery of replacement valves required for those operations. Subject to delivery of the valves and contractor mobilisation, wellhead maintenance is expected to commence late-November 2026. Slickline operations will follow completion of the maintenance operations. As previously announced, the results of these operations will determine whether further work, including a rig-operated workover, is required.

Ntorya to Madimba Pipeline (“Pipeline”)

The Tanzania Petroleum Development Corporation (“TPDC”) has confirmed that the Pipeline remains on schedule for completion in December 2026, when it will be ready to transport gas from Ntorya to the Madimba Gas Processing Plant.

Charles Santos, Executive Chairman of Aminex, commented:

“We are pleased to receive this latest progress update from APT. Operations at Ntorya are ongoing and the next few months should see a further increase in operational activity.

Ntorya is well positioned to contribute materially to meeting Tanzania’s growing demand for reliable and affordable energy for many years. Domestic natural gas has an important role to play in supporting electricity generation, industrialisation and wider economic development.

We remain focused on maintaining the current momentum and delivering first gas in December.”
