Enhanced subsurface understanding

Consolidating ownership within the GBA, acquired additional 70% working interest and operatorship in Licence P2170 increasing both our discovered and prospective resources

Strong cash position of approximately £8.9m at period end, c. £1m ahead due to cost discipline

The Greater Buchan Area

During the period, we acquired Equinor's 70% working interest in Licence P2170 (Blocks 20/5b and 21/1d), which contains the Verbier discovery, and as a result, we are now the operator of this licence, with a total working interest in the licence of 88%. We regard this as being strategically important to the Company, given that this acquisition increased both our discovered oil resources and our prospective resources.

We were also pleased to announce the appointment of Dr Chris Haynes, OBE, as an adviser to the Board, who is providing guidance and oversight to our GBA work programmes.
