Internal Resource Estimate

Matra Petroleum is pleased to provide the management's internal Resource estimate for the 100% owned Sokolovskoe oil field in Orenburg, Russia, based on the results of the recently competed seismic surveys.

As previously announced, the 3D seismic data interpretation identified that the Aphoninsky reservoir of the Sokolovskoye field splits into four separate domes within the boundaries of the license area from south-west to north-east. The integration of well data (A-12, A-13) with the recently interpreted 3D seismic data has resulted in an internal reclassification of Resources of the field.

The table below outlines management's Resources estimates for the sections of the Aphoninsky reservoir drilled by wells A-12 and A-13:

The Company is satisfied that these estimated Resources, taken in combination with its recently completed field development plan and associated economic forecast, and subject to the Company receiving the necessary regulatory approvals, would result in an independent Competent Person's Report confirming these as Recoverable Reserves.

The Company is actively reviewing its options for maximising the value of the Sokolovskoye field. These include progressing with early development of the field, proceeding with further appraisal activities targeting the upside potential of the field , which the company estimates includes further P50 Prospective Resources of 5mmbbls of recoverable oil, or considering existing options for monetising part or all of the asset. Depending on the next course of action the Company may commission an independent competent persons report over the Sokolovskoye field.

Commenting on today's announcement, Chief Executive of Matra Maxim Barskiy said:

"Today's announcement is an important step towards further demonstrating the significant potential of the Sokolovskoye field. We are now assessing the best way of realizing the value of the field for all shareholders and will give our recommendation in due course."
