Sentry Petroleum Uncovers Potential 2,000 Square Mile Coal Deposit in World Class Coal Seam Gas Region

Denver, Colorado (FSC – February 11, 2011) Sentry Petroleum Ltd. (OTCBB:SPLM) announced today that the company has delineated a potential world class coal and carbonaceous shale deposit within permits ATP 862 and ATP 864 in Queensland Australia.

Commenting on the size of the potential deposit, Sandy Belford, Sentry’s Chief Geophysicist stated: “We have completed an extensive geological, geophysical and engineering analysis on permits 862 and 864. The result is what our technical team has deemed ‘a potential coal and carbonaceous shale deposit in excess of 2,000 square miles.’ The data indicates net coal and carbonaceous shale seams in excess of 50 feet and 320 feet respectively, all situated at an optimal gas production depth of 300 to 1,600 feet.“

Sentry founder and VP of Exploration Alan Hart commented, “In the petroleum business success often happens this way. We were neither looking for coal nor did we expect to uncover any. We are extremely excited with our findings. Extensive data has been analysed but of particular interest is data from the Talundilly-1 well which revealed mud gas shows as high as 60,000 parts per million. This is indicative that the coal  zone does contain gas. Obviously these findings mandated an immediate corporate strategy shift.”

Arne Raabe, Sentry’s Business Case Specialist noted, “The current boom in coal seam gas acquisitions in Queensland provides an informative backdrop to view this development. In the last 24 months Chinese and international energy firms have spent billions of dollars acquiring junior coal seam gas companies. Sentry’s potential coal seam gas deposit, in excess of 2,000 sq. miles, compares favourably to deposits discovered by other recently acquired junior operators in Queensland. We believe our appeal to those large acquisitive energy firms will be enhanced.”

Sentry Petroleum President and CEO, Dr. Raj Rajeswaran summarized, “We are now focusing entirely on developing this potential coal seam gas deposit. We will engage the services of a leading coal expert to confirm our findings. Upon confirmation we will commence discussions with drilling contractors for an April drilling appraisal program in order to quantify the extent of the gas resource and its commerciality. Our confidence in the expeditious execution of our corporate strategy of ‘drilling, certifying and selling’ is clearly reinforced by this development.”

A Company spokesperson advised that the Company’s upcoming appraisal drilling program is fully funded. All interested parties are recommended to sign up on the Company’s web site for immediate delivery of corporate news and information.

Cautionary Note: The Company cautions that the estimated quantities of coal and carbonaceous shale disclosed in this press release represent an estimate of the potential of the noted permit areas based strictly on a review of technical data that is publicly available and are not intended to be construed in any manner as an estimate of any classification of reserves. Further appraisal is required before any estimated classification of reserves can be compiled. The Company’s upcoming appraisal drilling campaign is being undertaken in order to build the necessary data to be able to compile an estimate of reserves and make a later determination as to whether any noted reserves can be produced economically. There is risk that our upcoming appraisal drilling campaign will not be able to confirm the Company’s findings from its review of publicly available technical data.  The Company cautions that the results achieved by other companies operating in the region do not in any way indicate the presence of a commercially viable mineral deposit or oil and gas reserves on any of the Company’s permits.  Further exploration is required in order to be able to make a reserve estimate should the Company succeed in establishing that a commercially viable mineral deposit or oil and gas reserves exists on any of its property interests.
