Vaquero Announces Pembina Nisku Discovery

Vaquero Energy reports the recent discovery of a new Nisku pool in the Pembina area of west central Alberta. Preliminary results from the confidential well indicate a significant column of hydrocarbons in the Nisku formation. The well was drilled based upon the Company's interpretation of a 3D seismic program shot over the subject lands. Completion and testing of the well is planned for later in 2005. Future development of the pool will be determined upon evaluation of the test results.
