                          ("Aminex" or "the Company")

                            SIGNING OF RIG CONTRACT


Aminex PLC, the oil and gas company listed in London and Dublin, is pleased to
announce that its wholly-owned Tanzanian subsidiary Ndovu Resources Ltd has
signed a contract for the use of Maurel & Prom's Caroil-6 land drilling rig for
use at Aminex's Nyuni / East Songo Songo licence.

This rig has recently drilled Maurel & Prom's gas discovery well at the nearby
Mkuranga licence in Tanzania and will drill a development well in the Songo
Songo gas field before delivery to Aminex and partners, anticipated for late
May.  Aminex plans two wells at Nyuni, the first of which will be directionally
drilled from the small Killiwani island, which lies one kilometre to the SW of
Songo Songo Island.  The drilling objective is a prospect known as Songo Songo
South.

Brian Hall, Chief Executive of Aminex, commented:

"Securing the Caroil-6 rig is an important milestone in our 2007 drilling
campaign. We are looking forward to commencing operations at Nyuni and will
inform shareholders when there is further progress."
