December Production Report

7 January 2013

7 January 2013 - Exillon Energy plc (EXI.LN), a London Premium listed independent oil producer with assets in two oil-rich regions of Russia, Timan-Pechora ("Exillon TP") and West Siberia ("Exillon WS"), is pleased to announce unaudited production data for the month of December 2012 ("the Period").

·; Our average daily production1 was 16,114 bbl/day during the period.

·; Average daily production for Exillon TP was 3,694 bbl/day, and for Exillon WS it was 12,420 bbl/day during the period.

·; Our peak daily production2 was 17,532 bbl/day during the period.

We recently consulted with our major shareholders about the merits of publishing monthly production data. A large majority felt that monthly publication is excessive, and that quarterly publication would result in less volatility in our share price. We have therefore decided that in 2013 we will publish production data once a quarter.
