Independent Assessment of Horse Hill-1 Well

and Restoration of Trading

Solo is pleased to note the announcement by UK Oil & Gas Investments PLC ("UKOG") that Schlumberger, acting in an advisory capacity to UKOG, has independently evaluated the unconventional oil potential of the Horse Hill-1 well ("HH-1"), located in PEDL137 in the Weald Basin near to London Gatwick Airport, where the Company has a 6.5% interest.

Schlumberger has estimated a gross overall oil in place ("OIP") for the Jurassic section of the well to be approximately 271 million barrels of oil ("mmbbls") per square mile. A total of 255 mmbbls gross OIP lies within the tight limestone and mudstone plays of the Kimmeridge, Oxford Clay and Lias. The balance is in the Upper Portland Sandstone discovery previously announced. This figure of 255 mmbbls per square mile can be compared with the OIP estimated by NUTECH Ltd ("Nutech") and previously reported in April 2015 as gross 158 mmbbls per square mile.

Oil in place hydrocarbon volume estimates should not be construed as recoverable resources or reserves.

Neil Ritson, Solo's Chairman, commented;

"We are pleased to note that Schlumberger, using their own proprietary techniques, has confirmed the order of magnitude of the earlier work conducted by Nutech. Taken together these independent estimates continue to suggest a significant oil potential in the unconventional Jurassic sequence in the Horse Hill area and may have wider significance in the Weald Basin generally."
