Malta Update

Leni Gas & Oil plc today announces plans to acquire an additional 1,000 km sq of 3D seismic in Area 4, offshore Malta.

Mediterranean Oil and Gas plc as operator of the Area 4 PSC ("PSC") has contracted Fugro-Geoteam Pty Ltd to acquire the additional data using the vessel R/V Geo Barents which is presently mobilising to the location and is expected to commence acquisition around the 16 November 2011.

LGO owns a 10% interest in the PSC covering Blocks 4, 5, 6 and 7 offshore Malta adjacent to the internationally recognised border with Libya. The PSC was recently extended until 2013 and the additional seismic data was agreed in order to fully define a drilling prospect. Processing of the 3D will commence immediately after acquisition, which is anticipated to take about 30 days to complete, and will be available for interpretation in late 1st quarter 2012.

A number of prospects and leads have already been mapped within the PSC using existing 2D and 3D seismic data, with most likely unrisked prospective recoverable resources of oil totalling 1.5 billion barrels. The most mature prospects are located in Block 7 close to the Libyan pelagic basin and are the target of the new seismic data acquisition.

Neil Ritson, LGO's Chief Executive commented: "We are pleased to report progress towards drilling in Malta. Area 4 is surrounded by proven petroleum basins in Libya, Tunisia and Italy and we look forward to evaluating the new data ahead of selecting a possible drilling location in this prospective area of the Mediterranean."
