FURTHER FARMOUT OF NYUNI LICENCE IN TANZANIA

Aminex PLC ("Aminex"), the oil and gas company listed in London and Dublin, is
pleased to announce that it has signed a Farmout Agreement with East African
Exploration Limited ("EAX"), a Dubai-based oil and gas exploration company.

The Farmout Agreement provides for EAX to earn into part of Aminex's Nyuni
licence, offshore Tanzania by acquiring new "transition zone" 2D seismic over
Area "B" of the licence.  Area "A" of the Nyuni licence in Tanzania was partly
farmed out to East Coast Energy last year.  Splitting the licence remains
subject to approval by the Government of Tanzania.

EAX may further increase its interest by arranging the acquisition of 3D seismic
over the same area, if appropriate, after review of the first stage programme.
330 kilometres of new conventional 2D marine seismic was acquired over this area
by Aminex in 2005 and the additional transition zone seismic to be acquired by
EAX will add significant value to the existing data.  Transition zone seismic
involves special equipment to conduct seismic surveys in extremely shallow
marine environments not accessible to a conventional seismic vessel.  This is
particularly important at Nyuni where the majority of the potential drilling
locations underlie shoals, limestone reefs and small islands, many of which are
partly submerged at high tide.

EAX will acquire 2D transition zone data to a value of $2 million to earn an
interest of 15% in Area "B" of the Nyuni licence.  Subject to a review of the 2D
transition zone dataset, EAX will have the option to finance the acquisition of
prospect-specific 3D transition zone seismic to a value of $4 million, to earn
an additional 30% interest in Area "B".  In the event that the Government of
Tanzania does not approve the split of the Nyuni licence into Areas "A" and "B",
EAX will earn 10% of the entire licence area by shooting 2D transition zone
seismic rather than 15% of the smaller "B" area.  Similarly, by shooting 3D
transition zone seismic EAX will earn a further 20% interest in  the entire
licence area rather than 30% of the smaller "B" area.

The transition zone seismic and, if necessary, 3D seismic will be acquired
during the second and third quarters of 2006 with the aim of firming up drilling
targets for exploration wells.  The seismic crew will use state-of-the art
Sercel 428 TZ equipment and a custom-designed fleet of handling vessels.

The Government of Tanzania has formally consented to the introduction of EAX as
a farm-in partner to the Nyuni licence.

KENYA OFFSHORE UPDATE

On 14 March 2006, Aminex announced that it had entered into a seismic option
agreement with Upstream Petroleum Services Ltd. ("UPSL") over blocks L9 and L10
offshore Kenya.  Aminex confirms that under UPSL's Technical Evaluation
Agreement, 570  kms of new 2D seismic have now been acquired over the area  and
geochemical seabed coring and additional seismic on prospective leads will be
acquired in the next 2 months.  The area covered by this agreement is around
5,000 square kilometres, involving the land and near shore acreage  of original
Kenyan Blocks L9 and L10.  The remainder of Block L9 is licensed to other groups
and the deepwater portion of L10 is currently open.

Commenting on the further Nyuni farm-out, Aminex Chief Executive Brian Hall
said: "We are very pleased to welcome EAX as a new partner in our offshore Nyuni
acreage.  EAX and its sister company Upstream Petroleum Services Limited, our
partner in Kenya, will make a valuable contribution to the joint venture's
technical work.  The transition zone seismic and, if required, 3D seismic are
the final steps in firming up new drillable exploration prospects in the Nyuni
licence area."
