Sentry to Begin Drilling Drilling Shale Gas Appraisal in June

Sentry will commence drilling on the coal seam and shale gas appraisal program in Queensland on June 13, 2011. Following site visits last week, the final step during field preparation, the Company filed the necessary notices with Queensland government agencies and with the landowners.

In the first well, the Talundilly-CSG1, the primary target for Depco Rig 22 is the Winton coal and carbonaceous shale formation at approximately 600 to 1,500 feet. Coal and carbonaceous shale core samples will be retrieved and analyzed for gas content, coal quality, and methane storage capacity.
