Pantheon Resources : Discovery and successful conclusion of drilling operations at the VOBM#2H sidetrack well

26 January 2017

Pantheon Resources plc ("Pantheon" or "the Company"), the AIM-quoted oil and gas exploration company with a working interest of 50%-58% in several conventional projects in Tyler and Polk Counties, onshore East Texas, is pleased to provide the following information:

Pantheon confirms that the VOBM#2H sidetrack well, Polk County, onshore East Texas, has been drilled to a total measured depth of c.16,450 feet and will now be completed ahead of testing. Data from electronic logs indicates the presence of hydrocarbons in a potentially significant reservoir in the primary target, the Eagle Ford sandstone. The Board stresses however that the significance of these results cannot be accurately assessed until flow testing operations have been completed.

Drilling operations with this rig have now been completed at this location and a production liner will be run and the well bore cased. A lower cost workover rig will be contracted to undertake completion and flow testing of operations. A further update will be made once testing operations have been completed.

Pantheon confirms that completion operations are presently underway on the VOBM#4 well, following which the well will be tested. A further update will be issued at the end of testing operations.

"I am extremely pleased to report that we have successfully concluded the sidetrack of the VOBM#2H well and have encountered promising log responses. The successful completion of this well confirms our belief that we can drill vertical wells into the Eagle Ford, quickly and economically. We remain extremely excited by the potential of our prospects and we look forward to flow testing the VOBM#2H sidetrack well.

"We also look forward to flow testing the VOBM#4 well, which will provide valuable data on the recently discovered Wilcox formation and will provide a greater understanding of the potential significance of the zone for our Company. Should flow test results confirm the Wilcox to be a commercial producer on our acreage, then the company will expedite arrangements for first production in Tyler County, complimenting plans for first production in Polk County which are progressing well. Following analysis

of the testing results for VOBM#2H and VOBM#4 wells, the company will decide upon the location of the next well in the campaign."
