     HOUSTON--(BUSINESS WIRE)--March 31, 2006--Gastar Exploration Ltd.
(AMEX:GST) (TSX:YGA) reported a net loss attributable to common shares for the
three months ended December 31, 2005 of $4.8 million, or $0.03 per basic and
diluted common share, compared to a net loss of $9.4 million, or $0.08 per basic
and diluted common share, for the three months ended December 31, 2004. The 2004
quarterly loss included an impairment of natural gas and oil properties of $6.3
million. Total revenues for the three months ended December 31, 2005 were $9.9
million, an increase of $5.5 million, as compared to revenues of $4.4 million
for the 2004 comparable period. Of the 2005 quarterly increase in revenues, 45%
was the result of increases in the quarterly production, and 55% was
attributable to higher prices. Average daily production for the three months
ended December 31, 2005 was 13.0 million cubic feet of natural gas equivalents
per day ("MMcfed"), compared to 8.2 MMcfed for the three months ended December
31, 2004. EBITDA, as defined below, for the three months ended December 31, 2005
was $4.7 million, up from EBITDA of $1.1 million for the three months ended
December 31, 2004.
     Gastar reported a net loss attributable to common shares for the year ended
December 31, 2005 of $25.7 million, or $0.20 per basic and diluted common share,
compared to a net loss of $12.8 million, or $0.12 per basic and diluted common
share, for the year ended December 31, 2004. The net loss for 2005 and 2004
includes impairment of natural gas and oil properties of $8.7 million and $6.3
million, respectively. Total revenues for the year ended December 31, 2005 were
$27.4 million, an increase of $21.3 million, as compared to revenues of $6.1
million for the 2004 comparable period. Of the 2005 annual increase in revenues,
68% was the result of increases in the production, and 32% was attributable to
higher prices. Average daily production for the year ended December 31, 2005 was
10.5 MMcfe, compared to 3.1 MMcfed for the year ended December 31, 2004. EBITDA
for the year ended December 31, 2005 was $12.3 million, up from EBITDA of
$63,000 for the year ended December 31, 2004.
     Total proved reserves as of December 31, 2005 were 33.0 Bcf of natural gas
and 1,000 barrels of oil. The present value of estimated future cash flows
before income taxes as of December 31, 2005, based on the weighted average
natural gas and oil prices after basis adjustments of $56.00 per barrel and
$7.39 per Mcf and discounted at 10% per annum, was $91.3 million.
     J. Russell Porter, Gastar's President and Chief Executive Officer, made the
following comment, "We are pleased with our reported increases in production,
revenue and EBITDA. We anticipate continued improvement in operating results
during 2006 as we implement a more active drilling program in the deep Bossier
play and on our Australian coal bed methane properties. Our 2006 Donelson #1
discovery is currently producing at an approximate gross rate of 7.5 MMcfd (net
5.6 MMcfd) and appears to be stabilizing from the initial gross production rate
of 11 MMcfd. The Donelson #1 is our first commercial production in the lower
Bossier sands and appears to support Gastar's overall geologic and geophysical
model in these formations."
     Gastar Exploration Ltd. is an independent exploration and production
company focused on finding and developing natural gas assets in North America
and Australia. The Company pursues a balanced strategy combining select higher
risk, deep natural gas exploration prospects with lower risk CBM development
projects. Gastar owns and operates exploration and development acreage in the
Deep Bossier natural gas play of East Texas and in the deep Trenton-Black River
play in the Appalachian Basin. Gastar's CBM activities are conducted within the
Powder River Basin of Wyoming and upon the approximate 3.4 million acres
controlled by Gastar and its joint development partners in PEL 238, located in

Basin of Victoria, Australia.

(1) EBITDA represents earnings before interest expense, accretion of
    asset retirement obligations, depletion, depreciation and
    amortization, impairment of natural gas and oil properties and
    provision for income taxes. We have reported EBITDA because we
    believe EBITDA is a measure commonly reported and widely used by
    investors as an indicator of a company's operating performance and
    ability to incur and service debt. We believe EBITDA assists
    investors in comparing a company's performance on a consistent
    basis without regard to depreciation, depletion and amortization,
    impairment of natural gas and oil properties and exploration
    expenses, which can vary significantly depending upon accounting
    methods. EBITDA is not a calculation based on U.S. generally
    accepted accounting principles and should not be considered an
    alternative to net income (loss) in measuring our performance or
    used as an exclusive measure of cash flow because it does not
    consider the impact of working capital growth, capital
    expenditures, debt principal reductions and other sources and uses
    of cash, which are disclosed in our statements of cash flows.
    Investors should carefully consider the specific items included in
    our computation of EBITDA. While we have disclosed our EBITDA to
    permit a more complete comparative analysis of our operating
    performance and debt servicing ability relative to other
    companies, investors should be cautioned that EBITDA as reported
    by us may not be comparable in all instances to EBITDA as reported
    by other companies. EBITDA amounts may not be fully available for
    management's discretionary use, due to requirements to conserve
    funds for capital expenditures, debt service, preferred stock
    dividends and other commitments.



A reconciliation of net loss to EBITDA for the periods indicated
is presented below.
