NTORYA-1 DRILLING UPDATE

Aminex PLC ('Aminex' or the 'Company'), an independent oil company listed on the main market of the London and Irish Stock Exchanges with exploration and development assets in the emerging hydrocarbon province of East Africa, today announces an operational update on drilling of the Ntorya-1 exploration well in the Ruvuma Basin onshore in Tanzania.

The well was spudded on the 22 December 2011 and is now at a depth of 2500 metres. The targeted sandstone intervals were not encountered at the prognosed depths between 1,800 and 1,900 metres. Further drilling found sandstone intervals along with traces of gas below 2,300 metres. Wireline logs and check shot data will now be recorded to determine whether or not to drill further.

The Ntorya-1 well is designed to test the high quality Basal Tertiary and Upper Cretaceous sands previously encountered in the Likonde-1 well, 14 kilometres to the north.

Partners in the well are:

Ndovu Resources Ltd (Aminex) 56.25% (operator)

Tullow Tanzania B.V. 25%

Solo Oil plc 18.75%
