FOR IMMEDIATE RELEASE

20 August 2007
                     Aminex PLC ("Aminex" or "the Company")

                        Extension of Licence in Tanzania


Aminex PLC, the oil and gas company listed in London and Dublin, announces the
grant of a six-month extension to the current phase of its Nyuni/East
Songo-Songo exploration licence offshore Tanzania.  The two well drilling
programme planned for 2007 was due to be completed by the end of the current
phase in November but has been delayed due to mechanical hold-ups with the
current contractor's drilling rig, as previously advised to shareholders.  The
Tanzanian Minister of Energy and Mines has now granted a formal extension of the
Group's commitment period to 19 May 2008.

Commenting on the extension, Aminex Chairman Brian Hall said:

"As in the past, the Tanzanian authorities have been extremely helpful and
co-operative in resolving an issue which has arisen due to circumstances outside
our control. We are very grateful for their continued support. Subject to
unforeseen circumstances, we plan to have completed this drilling programme well
within the six month extension period."
