                        TANZANIA UPDATE - 16 JULY 2004

Aminex PLC, the oil and gas company listed in London and Dublin, announces
further developments associated with its Nyuni Licence, offshore Tanzania.

The Government of Tanzania ("the Government") has agreed to deem the recent
drilling of the Nyuni-1 well by Aminex and partners as having satisfied the work
obligation for the first exploration phase of the Nyuni Licence.  Aminex is
pleased to announce that the Government has therefore agreed to extend the
Licence into its second exploration phase and is additionally allowing the joint
venture until 30 November 2004 to finalise a work programme and complete a
re-appraisal of the licence in order to select acreage to be retained in
accordance with statutory requirements.

Nyuni-1, the group's first well on the licence, established the presence of
crude oil in an area previously regarded as purely gas-prone and confirmed the
prospectivity of the region, providing valuable information about the potential
of the permit.  Aminex intends to carry out a further exploration drilling
programme within the Licence.  It is likely that initial work on the second
phase work programme will include the reprocessing of existing seismic data and
the acquisition of new seismic within the licence area.

Tanzania is witnessing an increase in exploration activity following the recent
signing of three new Production Sharing Agreements by the Government; with
Maurel & Prom of France and Petrobras of Brazil for areas close to the Nyuni
Licence area and with the Artumas Group of Canada for the Mnazi Bay area in
southern Tanzania.

Partners in the licence are:

Ndovu Resources Ltd.            60%  (100% subsidiary of Aminex  plc)
Petrom SA                       30%
Bounty Oil & Gas NL             10%


                                                                    16 July 2004
