(ZEX - TSX Venture)(\"Zodiac\" or the \"Company\") announced today that its second evaluation well (the \"1-10 well\") on the Jaguar prospect in Kings County, California, has reached a total depth of 16,950 feet in the Cretaceous and the Company is now preparing to plug back and drill a horizontal leg into the Upper Kreyenhagen formation. \n1-10 Well\nThe 1-10 well, originally targeted to a total vertical depth of 15,240 feet, was deepened to test additional zones of interest including the Cretaceous Moreno formation, a significant source rock interval in this area, according to the USGS.  Petrophysical log and core analysis confirm prospective targets in the Whepley, Vaqueros, Upper Kreyenhagen, and Lower Kreyenhagen formations. The Upper Kreyenhagen zone, which was tested in the Company's 4-9 well, was cored in the 1-10 well. The overlying source shales and the siltstone reservoir target were cored with a total 110 feet recovered of a total Kreyenhagen thickness over 800 feet.  Visual examination of the core confirms the presence of oil stained fractures. \nThe well reached total depth at 16,950 feet on August 28, 2011, after intersecting sandstone, siltstone, and shale sections below the Kreyenhagen formation with high background gas readings and associated increases in C1-C5 on mud logs, and oil shows.  With formation pressures estimated in excess of 14,000 psi and significant mud log hydrocarbon response in the lower 250 feet of the wellbore, mudweight was increased to 16.4 pounds per gallon prior to stopping drilling.  As a result of deepening the well the Company has now identified several deeper potential targets.\nMurray Rodgers, President and CEO, commented, \"We are very pleased with the results from the drilling operations on the 1-10 well.  This well has confirmed the presence of deeper targets that our technical team had identified on 3D seismic acquired in 2009.   The Company is now preparing to plug back and drill a horizontal leg into the Upper Kreyenhagen formation. Further evaluation of the deeper zones with identified hydrocarbon potential will be undertaken in subsequent wel...
