Orca Exploration Group Inc. (“Orca” or the “Company”) announces that it has entered into an option with Neptune Petroleum (Uganda) Limited (“Neptune”), a wholly owned subsidiary of Tower Resources plc, to earn a 50% interest in the 6,040 sq km Exploration Area 5 license acreage, north western Uganda. The area is currently licensed 100% to Neptune.

“This is the first step in Orca’s announced intention to acquire an interest in two high potential oil exploration and development opportunities,” stated Peter Clutterbuck, Orca’s President and CEO. “We are very pleased to be working with Tower Resources and expect to begin a 2D seismic program of 250-300 kilometers in November 2007. Uganda is entering a very exciting phase in the development of its oil resources and Orca and Tower are looking forward to being part of it. We are also pleased to be working with Tower since both our companies have the same respectful and community-friendly approach to conducting business in Africa.”

Under the terms of the agreement, and in consideration for granting an interest option, Orca will fund 83.33% of the 2007 2D seismic programme and certain past costs, subject to a maximum carried cost of US$6 million. On completion of the interpretation of the seismic data, expected by Q1 2008, Orca will have the exclusive right to acquire a 50% working interest in Exploration Area 5 in return for funding 83.33% of two exploration wells. The carry to drill the wells is capped at a maximum cost to the Company of between US$10 million and US$15 million depending on whether the wells are tested. Contingent on the results of the seismic program, drilling of the two exploration wells could begin as early as mid-2008.

If Orca exercises its option to become a 50% partner, Orca will assume management responsibility for all drilling activities. Neptune will continue as operator under the licence for a period of three years.
