Gastar Exploration Announces Results of Operations for the Second Quarter Ended June 30, 2006

AUGUST 14, 2006 (HOUSTON, TEXAS) ... Gastar Exploration Ltd. (AMEX: GST; TSX: YGA) reported a net loss attributable to common shares for the three months ended June 30, 2006 of $6.7 million, or $0.04 per basic and diluted common share, compared to a net loss of $8.7 million, or $0.07 per basic and diluted common share for the three months ended June 30, 2005. The current quarter loss did not include a non-cash full cost ceiling impairment of natural gas and oil properties while the 2005 quarterly loss included a non-cash full cost ceiling impairment charge of $4.3 million. The net loss for 2006 includes a litigation settlement expense of $1.2 million. The 2005 quarterly loss also included the expensing of a $662,000 call premium and the expensing of $630,000 of unamortized deferred costs both related to the early retirement of the 15% senior notes in June 2005. Total revenues for the three months ended June 30, 2006 were $6.7 million, an increase of $1.8 million from revenues of $4.9 million reported for the comparable period in 2005. The 2006 quarterly increase in revenues was attributable to a 58% increase in the quarterly production which was partially offset by a 15% decline in natural gas prices. Average daily production for the three months ended June 30, 2006 was 13.2 million cubic feet of natural gas equivalents per day ("MMcfed"), compared to 8.4 MMcfed for the three months ended June 30, 2005. Second quarter 2006 production increased 19% as compared to first quarter 2006 production of 11.1 MMcfed.

Gastar reported a net loss attributable to common shares for the six months ended June 30, 2006 of $49.6 million, or $0.30 per basic and diluted common share, compared to a net loss of $16.3 million, or $0.14 per basic and diluted common share for the six months ended June 30, 2005. The six month losses for 2006 and 2005 included a non-cash full cost ceiling impairment of natural gas and oil properties of $37.3 million and $8.7 million, respectively. Total revenues for the six months ended June 30, 2006 were $13.3 million, an increase of $3.6 million from revenues of $9.7 million reported for the comparable period in 2005. Of the 2006 increase in revenues, 96% was the result of increases in production, and 4% was attributable to higher prices. Average daily production for the six months ended June 30, 2006 was 12.1 MMcfed compared to 8.9 MMcfed for the comparable 2005 period. EBITDA for the six months ended June 30, 2006 was $3.2 million, down from EBITDA of $4.5 million for the six months ended June 30, 2005 primarily due to $1.2 million of litigation settlement expense.

J. Russell Porter, Gastar's President and Chief Executive Officer, made the following comment, "Our significant growth in current quarter production is primarily the result of drilling successes in our East Texas Bossier play. We anticipate our production growth trend will continue with the recent announcement of the John Parker #1 log results and the anticipated results from the Wildman Trust #2 currently nearing total depth. Gastar is planning an increased level of activity with the addition of a third rig in early fourth quarter which should result in an ability to further increase production growth. A large scale 3-D seismic survey currently being permitted and acquired in the Hilltop area along with continued successful offset drilling by other operators should confirm that our Bossier acreage is well positioned and will be a vehicle for the creation of significant value for our shareholders in the future."
