DRILLING UPDATE

International Sovereign Energy is pleased to report that it has stimulated and performed a short flow test on Prevo 6-21-39-1W5 (75% working interest), in central Alberta. The initial indications are that the well should be capable of producing gas at a rate of 1 mmcf/d or 120 BOED net to the Company.  ISE anticipates the well will be on production by the third quarter this year.

Three wells drilled and cased during the first quarter in the Peace River region and in Medicine River of Alberta are being evaluated for multi zone completion opportunities. The wells will be completed and evaluated during the second quarter pending removal of road ban limitations and service rig availability.

International Sovereign continues to pursue its active drilling program with six (6) wells planned for drilling in Sinclair Manitoba, Medicine River, Forestburg, Marwayne and Milo Alberta during the months of May/June 2006.
