                                DRILLING UPDATE


Aminex notes an announcement posted on the website of Orca Exploration Ltd.
parent company of Pan-African Exploration Tanzania Ltd. ("PAT") on Sunday 17
June.

The Nyuni joint venture in Tanzania has contracted the Caroil-6 drilling rig to
drill two wells on the Nyuni East Songo-Songo PSA, as already announced to
shareholders. Under the contract this rig is due to be delivered to the Nyuni
partners as soon as a new development well, SS-10, has been completed on the
adjoining Songo-Songo gas field by PAT.

PAT had anticipated delivering the rig to the Nyuni partners this month but has
now announced that problems with mechanical equipment on the rig will result in
a temporary suspension of drilling operations at Songo-Songo while mechanical
repairs are carried out with the consequence that the rig will not now be
delivered to Aminex in June as planned.

Aminex anticipates that there may be a delay of several weeks. Meanwhile Aminex
has finalised agreements for services, supplies and personnel and extensive site
preparation is virtually complete. Shareholders will be kept advised of progress
on the rig repairs.
