Licence Award

Further to the announcement of 8 April 2016, Prospex is pleased to announce that Hutton Poland Limited ("Hutton"), has now been formally awarded the Kolo License. Prospex holds a 49% interest in Hutton.

Prospex has been advised by the directors of Hutton that the Boleshaw prospect on the Kolo Licence is ready for drilling, with a drill location determined. The Boleshaw prospect has been worked up using 1650km of 2D seismic already owned by Hutton. The licence award will allow the Hutton team to enter into the final stages of preparing to drill a well and it is anticipated that the first well will be drilled in 2016, subject to environmental permitting.

Further announcements will be made in due course.
