Mtwara licence extension and Ntorya-2 Appraisal Well Update

Aminex PLC, an independent oil and gas production and development company premium-listed on the London Stock Exchange and primary-listed on the Irish Stock Exchange with operations in Tanzania, is pleased to announce that the Mtwara Licence, of the Ruvuma Production Sharing Agreement ('Ruvuma PSA'), which was due to expire in December 2016, has received formal Ministerial approval and signature for an extension of one year until December 2017.

The Mtwara Licence includes the Ntorya Appraisal Area where the Company has an existing discovery well, which tested at 20 mmcf per day with 139 bbls of associated condensate.

Within the licence, civil work for the Ntorya-2 appraisal well has commenced and it is expected that the well pad will be completed within 10 weeks.

The Company has a 75% working interest and is the operator of this well which is positioned approximately 1500m South West of the Ntorya-1 discovery well. The well will satisfy the Company's appraisal drilling obligation after which the Company intends to apply for a 25-year development licence subject to its success.

London Address Change

Aminex also advices shareholders that it has changed its London representative office and the new address is 60 Sloane Avenue, London, SW3 3DD with immediate effect.
