Sundance Begins Seismic Program in Saskatchewan

Sentinel Rock, in conjunction with its proposed business combination with Sundance Energy, announced that Sundance has commenced a 41 square kilometer 3D seismic program on a portion of Sundance's land holdings in S.E. Saskatchewan which comprise approximately 70,000 net acres. The new 3D seismic program is designed to evaluate and confirm structures already identified on Sundance's proprietary licensed 2D and 3D data set comprised of 163 square kilometers of 3D and 436 kilometers of 2D seismic data.

From the existing geology and seismic data base Sundance has identified structures in the Second White Specks, Shaunavon, Torquay and Bakken formations. Sundance's lands where the current 3D program is being shot are located approximately 40 kilometers north and west of the Rocanville producing Bakken oil field and 29 kilometers north and west of the Wapella producing Shaunavon oil field.

It is anticipated that the new 3D seismic program will be completed by the end of March with processed and interpreted data available by May 2011. Drilling by Sundance of the first 2 Test Wells on its S.E. Saskatchewan lands will commence before August 2011.
