Gastar Exploration, Ltd. is an exploration and production company focused on finding and developing natural gas assets in North America and Australia. The Company pursues a balanced strategy combining low-risk CBM development with select higher risk, deep natural gas exploration prospects. Gastar is listed on the American Stock Exchange (AMEX) under the symbol GST and on the Toronto Stock Exchange (TSX) under the symbol “YGA.”

Coal Bed Methane
Gastar has interests in approximately 53,300 gross acres in Wyoming's Powder River Basin, one of the most active CBM plays in the U.S. Because the coals are very well understood, CBM development is generally lower risk. Gastar has begun commercial CBM production in the Powder River Basin and has entered into a joint venture to accelerate field development. Gastar is also pursuing CBM development on approximately 3.8 million acres with an estimated 54 trillion cubic feet of gas in place in New South Wales and Victoria, Australia.

Deep Natural Gas Projects
The Company has unique acreage positions in two of the most exciting deep natural gas plays in the United States; the Deep Bossier in East Texas and the Trenton-Black River Play in the Appalachian Basin.

Gastar and its partners control approximately 30,000 gross acres in the Deep Bossier, an active East Texas natural gas play, and have recently drilled two wells in the Hilltop area and have just begun drilling a third. In the Appalachian Basin, Gastar has acquired approximately 50,000 gross acres and has a catalog of seismically defined Trenton-Black River prospects, a deep gas exploration play with recent significant discoveries.
