CALGARY, ALBERTA -- (Marketwire - Feb. 14, 2013) - Anterra Energy Inc. (TSX VENTURE:AE.A) ("Anterra" or the "Company") announces that it has been advised by Terrex Energy Inc. ("Terrex") that the information circular respecting the proposed arrangement (the "Arrangement"), whereby Anterra will acquire 100% of the issued and outstanding common shares of Terrex, is expected to be mailed to the holders of Terrex shares and warrants on or about February 19, 2013.

Corporate Update

Anterra also announces it has filed restated financial statements, and the related management's discussion and analysis, for the three and nine months ended September 30, 2012. Subsequent to the issuance of the 2012 third quarter financial report, Anterra determined that an error in the measurement of the deferred tax expense (recovery) existed in the comparative information presented in the financial report. The result of the error is that deferred income tax recovery and net income for the three and nine months ended September 30, 2011 was overstated by $131,591 and $664,384, respectively. There was no impact to net cash from operating activities. These error corrections had been incorporated in Anterra's annual audited financial statements for the year ended December 31, 2011. The full text of Anterra's restated consolidated financial report and related management discussion and analysis can be found at www.sedar.com and on Anterra's website at www.anterraenergy.com.


Operations Update

Anterra also advises that since first production on December 28, 1012, the Pembina Buck Lake LSD 09-17 Cardium well has produced 14,141 barrels of oil equivalent (boe). The well continues to flow at average rates of 185 barrels of oil equivalent per day (boepd) comprised of 90 barrels of oil and 570 mcf of gas per day at a tubing pressure of 1400 kpa. Anterra holds a sixty percent (60%) working interest in the well and the balance of Section 17.

At Abbott in south east Saskatchewan, the Company's Bakken test well at LSD 16-35-07-18W2M has reached core point. Following coring of an 18 meter section through the Bakken the well will be drilled to the Duperow formation. Following logging and coring, the Company will make a decision on whether to re-enter the well and drill the horizontal leg. Anterra has farmed out the test well and retains a fifty percent (50%) working interest in the test well and the adjoining 26 sections of land following the expenditure by its joint venture partner of $2 million.
