Excelsior Adds 18 Sections of Oil Sand Leases in the West Surmont, Athabasca Oil Sands Area

Excelsior Energy Limited is pleased to announce it has signed a binding Farm-in Agreement with an Alberta based private company, ("AlbertaCo") to acquire a 75% interest in 18 contiguous sections (11,520 acres) of land in the West Surmont area south of Fort McMurray ("the Asset"), in the heart of the Athabasca oil sands area.

The Asset is located in close proximity to a number of active SAGD (steam assisted gravity drainage) Projects which are in various stages of development which include ConocoPhillips' Surmont Project, and Statoil's Leismer and Corner Project areas.

Excelsior is acquiring its interest by paying 100% of the accrued land costs, future seismic and drilling costs totalling $21.6 million, and a cash bonus of $2.3 million to earn its 75% interest. The cash payment will be made upon completion of the seismic program. The Company has also agreed to pay AlbertaCo a supplemental payment of up to $2.9 million which is contingent upon successful drilling results and the parties agreement to continue operations, and is payable by funding AlbertaCo's 25% share of continuing operations.

The productive reservoir is the McMurray Formation which is comprised of high quality fluvial and estuarine channel sands. There are 13 wells drilled on the Asset and a further 25 wells drilled on adjacent sections that confirm the presence of the reservoir oil sands with gross oil sand thicknesses ranging between 8 meters and 29 meters.

The first stage of the project is to shoot approximately 108 kilometres of 2D seismic to tie the existing wells and to delineate the size and number of potential SAGD oil sand pods. The Company is investigating the possibility of acquiring the seismic program in late summer and we will provide an update once the timing is confirmed. An exploration well program of 18 wells to further delineate the potential SAGD Pods and identify a core area for a pilot project, is planned for winter 2007/8. The Company anticipates engaging a third party, National Instrument 51-101 compliant engineering evaluation once the 2D seismic has been acquired, processed and interpreted.
