                          ("Aminex" or "the Company")

Over 15 per cent.  of Aminex Shareholders Cannot or Will Not Accept Apple Offer


The Board of Aminex is pleased to announce that it has today received additional
irrevocable undertakings not to accept the offer made by Apple Oil and Gas
Limited ("Apple") in respect of a further 1,050,000 shares of Aminex,
representing approximately 1.2 per cent. of Aminex's total issued share capital.
These undertakings will cease to be binding after 30 September 2002. The
majority of these shares are currently held in the name of Forest Nominees
Limited.

This follows Aminex's announcement of last week, when it stated that holders of
a total of 10,504,870 shares of Aminex, representing 11.6 per cent. of Aminex's
total issued share capital, had either irrevocably undertaken not to accept
Apple's Offer or were prevented from selling or otherwise disposing of the
relevant Aminex shares prior to 1 September 2002.

In addition, all of the Directors of Aminex, whose combined shareholdings total
2,732,953 shares in Aminex, representing approximately 3.03 per cent. of
Aminex's total issued share capital, have undertaken not to accept Apple's
Offer.

Therefore, as of today's date, holders of a total of 14,287,823 shares in
Aminex, representing approximately 15.84 per cent. of Aminex's total issued
share capital, have either undertaken not to accept Apple's Offer or are
prevented from selling or otherwise disposing of the relevant Aminex shares
prior to 1 September 2002.

                                                                   17 April 2002
