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

AMINEX RAISES US$1.7 MILLION TO EXPAND US ACTIVITY

Aminex PLC has been offered participation in an exploration project by a major regional operator in Louisiana, with leads and prospects identified by 3D seismic across 140,000 acres. To be able to take advantage of this offer, which is a logical and complementary extension to Aminex's ongoing operations at Shoats Creek, Louisiana, and to provide the flexibility to contribute to the development of the project, Aminex has, through its brokers Astaire Securities and Davy, procured subscribers for 17,200,000 new ordinary shares ("New Ordinary Shares") at a price of 7p per share. The issue of these New Ordinary Shares, representing in aggregate approximately 4.2% of the existing issued share capital of the Company, is within existing allotment authorities granted by shareholders. This placing will raise approximately £1.2 million (approximately $1.7 million) net of expenses, which, subject to final negotiation, should enable Aminex to acquire a minority but meaningful share of the new exploration project without the need to reallocate budgeted funds within the Aminex group. Further announcements in relation to Aminex's planned investment in this exploration project will be made in due course following finalisation of all negotiations.

Application is being made to the Irish Stock Exchange and the UK Listing Authority for the 17,200,000 New Ordinary Shares being issued under this placing to be admitted to the Official Lists and application is being made to the Irish Stock Exchange and the London Stock Exchange for such New Ordinary Shares to be admitted to trading on their respective regulated markets for listed securities. It is expected that such admission will become effective and that dealings will commence in the New Ordinary Shares at 8.00 a.m. (London and Dublin time) on 16 June 2010.

Aminex chairman Brian Hall commented: "This is an exciting opportunity to expand our interests in an area which we now understand well and where we currently operate. In the same general area the Olympia Minerals-1 well (OM-1), which was drilled earlier in the year, encountering multiple thin sand formations, has been subject to a long-term and complex testing procedure. It is now likely to be completed in the Cockfield-2 sands at a depth of around 8,600 feet. The deeper sands in the Cockfield-2 zone have already flowed oil under test and the main part of the Cockfield-2 will be perforated shortly, the two sands then most likely then being commingled for production. Shareholders will be advised as soon as the test is complete".
