Pantheon Resources : Operational Update - August 2017

9 August, 2017

Pantheon Resources plc ("Pantheon" or "the Company"), the AIM-quoted oil and gas exploration company with a working interest in several conventional projects in Tyler and Polk Counties, onshore East Texas, is pleased to provide the following update:

Pantheon is pleased to confirm that the fracture stimulation procedure ("Frac") on the VOBM#2H well, designed to remediate near wellbore skin damage caused during horizontal and deviated drilling, has been completed.

Initial results indicate that the Frac has been successful, with the well, which is presently in the process of recovering frac water, flowing both gas and oil to surface. The Company cautions however that it is too early to make an accurate assessment as to the ultimate performance of the well until the remaining frac water has been recovered, production tubing installed and flow testing completed.

A workover rig is required to install the production tubing and this procedure and subsequent testing is estimated to take a further three weeks on a trouble free basis. Results will be reported at the conclusion of testing operations.

The operator has been notified that the mobilisation and delivery of the drilling rig, contracted for the planned sidetrack of the VOBM#4 well is now expected during the second week of September 2017. This is due to the third party currently utilising the rig, requiring it for longer than initially forecast.
