                AMINNEX PLC ANNOUNCES E-COMMERCE JOINT VENTURE


Aminex  PLC  (the  'Company')  the  oil and gas  development,  production  and
oilfield services group listed on the London and Dublin Stock Exchanges  today
announces  that  it  has  formed  a  joint  venture  with  ci4net.com  Limited
('ci4net.com')  to develop an Internet market place for oil field  procurement
and technical services.

Under  the terms of the joint venture, the Company has agreed to transfer  the
entire issued share capital of its existing and well established services  and
supply division, Aminex Oilfield Service & Supply Company Ltd, ('Amossco')  to
a  newly incorporated company (the 'new company'), which will act as the joint
venture  vehicle,  in return for 500 shares of £1 each in  the  joint  venture
company  which  will  be retained by the Company.  ci4net.com  has  agreed  to
subscribe  for  500  shares of £1 each in the new company  at  par.   The  new
company  will  operate as a 'deadlock' joint venture with board representation
from both the Company and ci4net.com.

The  new  venture  will provide online access to Amossco's  business  and  the
technical  expertise  to  achieve this will be provided  by  ci4net.com.   The
Company  believes that the Internet platform will allow Amossco to expand  its
business and operate more efficiently, giving it access to a larger market.

As  part  of  the  deal  the Company will continue to  route  its  procurement
requirements  for its exploration and production activities  through  the  new
joint  venture.   The  joint  venture will create a  competitive  business  to
business   (B2B)  platform  based  on  the  existing  customer  and   supplier
relationships.

Amossco  has  two  divisions, Amossco ODS and Amossco  Halyard.   Amossco  ODS
procures and markets oilfield and related equipment internationally from bases
in London and Houston and is also an industrial products distributor.  Amossco
Halyard is a technical consultancy that also provides management and marketing
services. At 31 December 1999, Amossco had net assets of $335,000 and for  the
year ended 31 December 1999 reported an operating loss of $755,000.

ci4net.com  is  a  global  economic network of  e-commerce  partner  companies
focused on adding value, stability and growth.



Commenting on the announcement, Brian Hall, Chief Executive of Aminex, said:

'This is a significant move for Aminex as it will allow the oil field services
division  to  access a much larger market and will provide our customers  with
the flexibility which online procurement can offer.  We believe that Aminex is
well  placed to develop such a market as it already has expertise in oil field
services.  It  will  be among the early companies to offer such  products  and
services  over  the Internet.  We are very pleased to have ci4net.com  as  our
joint  venture  partner as they are highly experienced and have  a  successful
track record in providing B2B e-commerce solutions.'
