 Ororo Update - Seabed Survey

Sirius Petroleum (AIM: SRSP), the investing company focused on oil and gas exploration and development opportunities in Nigeria, is pleased to announce that it has executed a contract with Polaris Consulting Company ("Polaris") which has been engaged to undertake a Seabed Survey around the Ororo field licence area. The marine vessel conducting the survey will mobilise to site in early April and it is anticipated that the survey will take approximately two weeks to complete.

This activity is a geophysical and geotechnical marine survey, ahead of the rig mobilisation, which will provide data and analysis for the rig positioning prior to drilling and assess any marine geohazards to ensure safe operations and transportation of equipment. This is a requirement by rig providers and as such the Company has been instructed by COSL Drilling Pan-Pacific ("COSL") to conduct this survey in order to finalise the rig selection from the fleet of Jack-up rigs owned by COSL, ahead of the anticipated multi-well campaign.

Bobo Kuti, CEO of Sirius, commented:

"We are pleased to have signed this contract with Polaris and look forward to receiving the results of the seabed survey in due course. This is another important step forward and when completed will allow the Jack-up rig to be mobilised to site."
