   Aminex successfully tests a well re-completion in Shoats Creek, Louisiana


Aminex  PLC  ('Aminex') the oil and gas development, production  and  oilfield
services  group,  listed on the London and Dublin Stock Exchanges,  today
announces that its wholly owned subsidiary, Aminex USA Inc, has successfully
flow tested the re-completion of the Cain No. 1 well on its Shoats Creek Field
in Beauregard, Parish, Louisiana.  The well tested at rates of 145-170 barrels
of  oil  per  day and 200 Mcf of gas per day on an 14/64ths. choke  from  the
Cockfield  formation  at a depth of approximately 8,900 feet  (2,715  metres).
Aminex  owns  and  operates  this field and is now preparing  to  implement  a
development programme for the re-completion of additional well bores  and
the  construction  of production facilities. This programme  is  being  funded
under the financing arangement with McAlester Fuel Company announced in
September 1999.

The  Cain No. 1 well is expected to produce, on artificial lift, approximately
150  barrels  of  oil  per  day  as  soon as  the  production  facilities  and
connections for the delivery of gas are completed.

Commenting on the announcement, Brian Hall, Aminex Chief Executive, said:
'Recompletion of the Cain No. 1 well is part of Aminex's major drilling and
well re-completions  programme on its extensive inventory of leases in the
onshore Gulf Coast area of Texas and Louisiana.  This programme is on track to
drill 15 new wells in  the  first half of 2000 and has already increased
production by  over 500 barrels  per  day in the U.S., enabling the group to
take early  advantage  of current  high  oil prices.

'This  is  a  very  exciting and active period for Aminex in the  USA.  Having
acquired significant acreage on advantageous terms  during  the  oil price 
slump of  1998-99, we are now well placed to exploit its potential in a strong
oil market.  The results of recently drilled  wells  on the group's Vinton
Dome Field will be announced once partner restrictions have been lifted and
partners' interests have been finally determined.'
