Senior Management - Mr Peter Gregory

Sirius Petroleum Plc ("Sirius" or the "Company")

Peter Gregory

It is with great sadness that the Directors announce that Peter Gregory has died suddenly whilst at home in the UK. Peter was appointed Chief Operating Officer of the Company on 12 April 2017, and whilst he was not a member of the main Board he was an important and much valued member of the operational management team and he worked tirelessly to lay the foundations for the Company's Ororo drilling programme.

Whilst the Company does have depth in its operational management team and of course the considerable support of its group of operational partners, the Board is taking immediate steps to put in place an experienced COO with the requisite skill set.

Chairman of Sirius, Jack Pryde, said: "Peter will be greatly missed by us all at Sirius as a work colleague and a personality with great energy and expertise who commanded much respect by each member of the team. Our very sincerest thoughts are with his family at this time."
