                             Result of Rights Issue



Aminex PLC today announces that it has received valid acceptances in respect of
14,465,371 New Ordinary Shares, representing approximately 51.4 per cent. of the
total number of New Ordinary Shares offered to Qualifying Shareholders pursuant
to the 1 for 6 non-underwritten rights issue announced by Aminex on 15 May 2007
(the "Rights Issue").

In accordance with the terms of the Rights Issue, Davy and Bridgewell may now
seek to procure subscribers for the shares which were not validly taken up in
the Rights Issue, including fractional entitlements and the entitlements of
overseas shareholders who were unable to participate. A further announcement in
relation to any such placing will be issued in due course.

Brian Hall, Chief Executive of Aminex, commented:

"We are very pleased that so many shareholders decided to take up their Rights.
With funding in place and joint venture partners on board, we are now very well
placed for significant activity in our key areas of exploration."

Definitions used in the Prospectus dated 23 May 2007 shall have the same
meanings when used in this announcement.
