FOR IMMEDIATE RELEASE

                     Aminex PLC ("Aminex" or "the Company")

                                   Rig Update


Aminex PLC ("Aminex" or the "Company") provides the following update on its
forthcoming drilling operations in Tanzania:

As previously announced, the Caroil-6 drilling rig, for which Aminex and
partners have a contract to drill two exploration wells on the Nyuni licence
offshore Tanzania, experienced delays due to the need for remedial work and
upgrading.  The Caroil-6 rig is currently on location in the adjoining
Songo-Songo gas field working for Pan-African Tanzania Ltd.

Current information is that remedial work to the rig will be completed by
mid-August following which it will complete its work at Songo-Songo.  It is
anticipated that the rig will be delivered to the Nyuni partners in late
September and will be ready to spud Kiliwani-1, first of two locations in the
current Nyuni programme, in the first half of October.

Aminex Chairman Brian Hall commented: "Frustrating as this delay has become, we
have used the time well to fine-tune our operational procedures, materials
procurement and supporting contracts.  The delay is outside our control but we
may be confident that the rig, once it has passed inspection, will be in first
class operational order".


The Nyuni partners are:

Ndovu Resources Ltd. (operator)              39%(wholly-owned by Aminex)
Key Petroleum Ltd.                           20%
RAK Gas Commission                           25%
East Africa Exploration Ltd.                 10%
Bounty Oil & Gas Ltd.                        6%



Elsewhere in the region, Aminex has commenced major onshore seismic programmes
in the Ruvuma Basin of Tanzania and over the Manja licence in Madagascar, in
preparation for drilling in 2008.
