Sentry Petroleum Appoints Leading U.S. Coal Seam Gas Expert  

Denver, Colorado (April 27, 2011 - FSC) Sentry Petroleum Ltd. (OTCBB:SPLM) is pleased to announce that Dr. Charles Barker has joined the company as Vice President for Unconventional Resources. Dr. Barker will be responsible for managing the upcoming geological appraisal program in ATP 862 and ATP 864 in Queensland planned to commence in May 2011.  

President and CEO Dr. Rajeswaran commented on the appointment, “We are delighted to welcome Charley as a member of our management team. His wealth of experience and know-how in appraising CSG assets will be of great value during our forthcoming drilling program.”

Dr. Barker commented, “I certainly will be challenged by the enormity of exploring and developing a stacked coal seam and associated gas shale sequence hundreds of feet thick located in Sentry's ATP 862 and 864. Gas shows indicate it is gassy, now we just need to find the sweet spot to make it productive. I appreciate Sentry bringing me on board to make this happen and enthusiastically seeking the ways and means to delineate the resource. ”
