Aminex PLC, the oil and gas company listed in London and Dublin, provides a
further progress report for the Nyuni-1 well, offshore Tanzania.



The well has now reached a depth of 3,365 metres and wireline logging has
commenced.  Following evaluation of the logs a decision will be made either to
initiate a suitable testing programme at this depth or to drill ahead deeper
into the Neocomian formation.



Nyuni-1 is the first of two sequential wells being drilled on the Nyuni offshore
licence using an F200 land rig owned by Dafora Drilling of Romania and operating
from small islands.
