Groundstar Resources Limited: Takutu Basin, Guyana Farm-In Resource Estimate Clarification

CALGARY, ALBERTA--(Marketwire - March 13, 2008) -

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES. ANY FAILURE TO COMPLY WITH THIS RESTRICTION MAY CONSTITUTE A VIOLATION OF U.S. SECURITIES LAWS.

Groundstar Resources Limited ("Groundstar or the "Company") (TSX VENTURE:GSA) announced on March 12, 2008 that the Company has entered into a Preliminary Farm-In and Standstill Agreement (the "Farm-in Agreement") with an industry partner (the "Farmee") on its Petroleum Prospecting License ("PPL") in the Takutu Basin in Guyana.

Under the terms of the Farm-in Agreement, the Farmee will pay 100% of all exploration expenses up to US $12 million to earn an undivided 55% Working Interest in the block. The Farmee has the option to increase its Working Interest by 10% to 65%, exercisable any time before July 22, 2008 by issuing to Groundstar, CND $1 million worth of the Farmee's securities. As a condition of the Farm-In Agreement, Groundstar has agreed to a standstill clause whereby it will refrain from completing any transaction with any other party on the PPL until March 22, 2008 for a break fee of US $500,000.

Groundstar is extremely excited to enter into this Farm-In Agreement as it will lead to the drilling of a minimum of two to three exploratory wells. It is anticipated that the wells will be drilled in Q4 2008 to Q1 2009.

Groundstar has three large seismically defined prospects on the PPL with a combined P90 Resources Estimate of 177 million barrels. The Karanambo #1 well drilled by Home Oil in 1982 tested 411 bopd (42 deg API) during a 5 hour drill stem test proving the Basin has all the essential elements of a petroleum system. The fiscal terms of the PPL are very favorable.



The following tabulates the resource estimates for the three prospects:

----------------------------------------------------------------------------
Recoverable Resource (MMBO)
----------------------------------------------------------------------------
Prospect P90 P50 P10
----------------------------------------------------------------------------
Karanambo 36.2 58.8 90.3
----------------------------------------------------------------------------
Pirara River 31.2 50.5 77.7
----------------------------------------------------------------------------
Rewa 109.5 195.2 309.9
----------------------------------------------------------------------------
Total 176.9 304.5 477.9
----------------------------------------------------------------------------


These estimates were based on evaluations of 2600 km of seismic data acquired by previous operators of the PPL, namely, Home Oil and Hunt. The petro-physical parameters are based on a study by Servipetrol Ltd., an independent consultant specializing in fractured reservoirs. The resource estimates were developed internally in January 2008 by Frank Crawford and Dr. Eric Sennhauser, geologist and engineer for this project.

The stated resource estimates noted above pertain to an undiscovered resource and there is no certainty that the undiscovered resource will in fact be discovered and that, if discovered, will be economically viable and technically feasible to produce.

Groundstar is a publicly traded Canadian junior oil and gas company actively pursuing exploration opportunities in Guyana, North Africa and the Middle East.
