DENVER, Oct. 26, 2012 /PRNewswire/ -- Antero Resources announced today that the borrowing base under its bank credit facility has been increased to $1.65 billion. This represents a $300 million increase over Antero's previous borrowing base which was determined in May 2012 and further revised following the Arkoma asset sale in June 2012. Lender commitments under the facility were raised to $950 million, a $200 million increase. The $950 million commitment can be expanded to the full $1.65 billion borrowing base upon bank approval.
