Anterra Provides Operations Update

CALGARY, ALBERTA – June 1, 2011. Anterra Energy Inc. (“Anterra” or the “Company”) is pleased to
provide the following operations update.

BUCK LAKE LSD 01‐17‐45‐5W5M: This horizontal Cardium well continues to flow at greater than 150 boepd, with cumulative production of over 30,000 boes since production started on February 14, 2011. The Company has a sixty (60%) percent working interest in the well and plans to install artificial lift during June, 2011.

BUCK LAKE LSD 08‐17‐45‐5W5M: The horizontal leg of this sixty (60%) percent working interest Cardium well was drilled in April and the completion of the well including multi stage “fracing” is now scheduled for mid June 2011. This is a look alike well to the LSD 01‐17 well. Following completion the well will be tied into the central production facility and placed on production.

SASKATCHEWAN BAKKEN PROJECT: Anterra has scheduled the drilling of its one hundred (100%) percent working interest Bakken test well at LSD 09‐36‐07‐18W2M for mid June 2011. This vertical test well will be logged and cored. If the Bakken formation proves to be prospective for oil a horizontal leg will be drilled and the well will be completed using multi stage “fracs”. A successful Bakken well will lead to further development as the Company owns 26 sections of land in the immediate vicinity of the
test well. The Company also intends to test the Birdbear and Duperow formations in the well.

CHINA AND SOUTH EAST INVESTOR RELATIONS TRIP:
The Company also wishes to advise shareholders that management recently visited China and presented
to over sixty (60) persons in both Beijing and Shanghai. A copy of the Company’s Asian tour presentation is now on the Company’s web site at www.anterraenergy.com

Reader Advisory:
This news release contains certain forward‐looking statements, which include assumptions with respect to future operations. The reader is cautioned that assumptions used in the preparation of such information may prove to be incorrect. All such forward‐looking statements involve substantial known and unknown risks and uncertainties, certain of which are beyond the Company’s control. Such risks and uncertainties include, without limitation, risks associated with oil and natural gas exploration, development, exploitation, production, marketing and transportation, volatility of commodity prices, availability of drilling rigs and other services, delays resulting from or inability to obtain required regulatory approvals and ability to access sufficient capital from internal and external sources, the impact of general economic conditions in Canada and the United States, industry conditions, changes in laws and regulations (including the adoption of new environmental laws and regulations) and changes in how they are interpreted and enforced, the lack of availability of qualified personnel or management, fluctuations in foreign exchange or interest rates, and stock market volatility. The Company’s actual results, performance or achievements could differ materially from those expressed in, or implied by, these forward‐looking statements and, accordingly, no assurances can be given that any of the events anticipated by the forward‐looking statements will transpire or occur, or if any of them do, what benefits, including the amount of proceeds, the Company will derive there from. Readers are cautioned that the foregoing list of factors is not exhaustive. A BOE conversion ratio of 6 Mcf: 1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
