Drilling Update: Silverfox-1 Shale Exploration Well Completed

Exoma Energy Limited (ASX: EXE) announces the Silverfox-1 exploration well in ATP 1005P has been completed.

The well was drilled to a total depth of 1170.7 metres and cutting samples of the Toolebuc shale were collected. The shale samples will be subject to geochemical analysis; it is expected that this information will become available for interpretation in early 2013. The data from this well forms part of the Galilee Joint Venture’s assessment of the extent of maturity of the Toolebuc shale as an oil and gas resource.

The well has been suspended as a water monitoring bore.

This concludes Exoma’s 2012 drilling programme and the EDA #1 drill rig has now been released. Twelve wells were drilled during 2012. The 2012 well locations are shown on the attached map.

Exoma has a 50% beneficial interest in both ATP 1005P and the Silverfox-1 well. CNOOC Galilee Gas Company Pty Ltd is earning its participating interest by a farmin whereby CNOOC provides the first $50 million of joint venture expenditures on Exoma’s five Galilee Basin ATP’s.
