The Polish Ministry of Environment has approved the merging as part of the modification of the Rawicz Concession and the new merged concession area is 742 km2 (183,352 acres).

The merged concession includes discovered but unproduced Rawicz gas field in the Permian Main Dolomite and Rotliegendes formations.

San Leon chairman Oisin Fanning said, "AS we continue to expand our Permian/SW Carboniferous acreage in Poland we see the addition of the Rawicz gas field as key to our strategy to focus on near-term production to generate cash flow while we continue to understand the significant upside present in the deeper Carboniferous."

The Company is estimating the Rawicz gas field to contain up to 17bcf of recoverable methane gas in the Permian Rotliegendes formation with potential upside for oil and gas production the Zechstein Main Dolomite.

The company through its subsidiary, NovaSeis, is also planning to acquire an estimated 120 km2 3D seismic survey over the Rawicz gas field in the final quarter of 2012.

San Leon holds 100% interest in the expanded Rawicz concession.

San Leon Energy is an international group of companies focused on the exploration and production of oil and gas projects.
