Dec 12, 2005 - 09:01 ET Antrim Energy Inc.: Argentina and UK Operations Update

CALGARY, ALBERTA AND LONDON, UNITED KINGDOM--(CCNMatthews - Dec. 12, 2005) - Antrim Energy Inc. (TSX:AEN) (AIM:AEY):

The primary target zone in the recently drilled and cased Los Patos 1002 well in Tierra del Fuego, Argentina has tested a flow rate of 12.4 MMcf/d with associated liquids from a single 4 metre thick net pay section. The initial flow rate had a flowing pressure of 1400 psi. Further testing is underway to establish stabilized flow rates over various pressures. However, the measured flow rate from Los Patos 1002 represents a substantial increase over the 1-2 MMcf/d average initial flow rates obtained from gas wells in the area.

Drilling operations have started on the second well, Los Flamencos 1001a, in Antrim's multi-well Tierra del Fuego drilling program. This well should reach total depth prior to year end. Antrim's working interest in the Tierra del Fuego licences is 25.8%.

In the United Kingdom, Antrim has been informed by Dana Petroleum (E&P) Ltd. (Operator) that drilling operations have been concluded on the Clachnaben well, Block 211/22a in the UK North Sea. Interpretation of the data received to-date indicates that hydrocarbons are not present in commercial quantities. Antrim has agreed with the operator that the well should be plugged and abandoned. As described in the press release issued March 21, 2005, Antrim farmed out its interest in this well to Dana in return for a minority interest in the licence.

The Clachnaben drilling result does not reduce the prospectivity of Antrim's nearby Causeway prospect, in which Antrim holds a majority interest.

As previously announced in the press release issued 28th November, 2005, Antrim's third well in its 2005 North Sea drilling program, "Bennachie" operated by Nexen Petroleum U.K. Limited, is currently drilling in Block 21/15a.

Certain statements contained in this press release may be considered as "forward looking". Such "forward looking" statements are subject to risks and uncertainties that could cause actual results to differ materially from estimated or implied results.
