Exhibit 99.1

                     Contango Announces Results of
          Operations for the Fiscal Year Ended June 30, 2005

    HOUSTON--(BUSINESS WIRE)--Sept. 13, 2005--Contango Oil & Gas
Company (AMEX:MCF) reported net income attributable to common stock
for the year ended June 30, 2005 of $12.0 million, or $0.92 per basic
and diluted share, compared to net income attributable to common stock
for the year ended June 30, 2004 of $7.1 million, or $0.68 per basic
and diluted share. Natural gas and oil sales from continuing and
discontinued operations for the year ended June 30, 2005 were $16.3
million, down from $27.6 million for the year ended June 30, 2004. The
decrease in revenue was primarily the result of the sale of our south
Texas natural gas and oil interests for $50 million, completed in
December 2004. EBITDAX was $28.5 million for the year ended June 30,
2005, down from EBITDAX for the year ended June 30, 2004 of $29.0
million.
    For the three months ended June 30, 2005 Contango had a net loss
attributable to common stock of $1.4 million, or $0.16 per basic and
diluted share, compared to a net loss attributable to common stock for
the three months ended June 30, 2004 of $1.1 million, or $0.09 per
basic and diluted share. Natural gas and oil sales from continuing and
discontinued operations for the three months ended June 30, 2005 were
$1.3 million, down from $6.8 million for the three months ended June
30, 2004.
    Kenneth R. Peak, Contango's Chairman and Chief Executive Officer,
said, "Fiscal-year 2005 was a productive year for us. We sold the
majority of our south Texas natural gas and oil properties in
December, paid-off all of our bank debt, greatly increased our
liquidity, and positioned ourselves strategically by making
substantial capital commitments to our Fayetteville Shale prospect
area and our two offshore exploration prospects, Eugene Island 10
("Dutch") and Grand Isle 72 ("Liberty"). We currently have production
of approximately 1,860 Mcfe/d and approximately $29 million in cash,
cash equivalents, and short-term investments."
    Mr. Peak continued, "Since its inception in 1999, Contango has
primarily been a company focused on south Texas exploration and the
generation of offshore prospects that were subsequently sold on a
promoted basis to the industry. In the future, we will be a company
focused on developing our Fayetteville Shale play in Arkansas,
operating certain of our offshore prospects, maintaining our 10%
limited partnership interest in our Freeport LNG project, and maturing
our investments in alternative energy."

(1) EBITDAX represents earnings before interest, income taxes,
    depreciation, depletion and amortization, impairment expenses,
    exploration expenses, including gain (loss) from hedging
    activities, and sale of assets and other. We have reported EBITDAX
    because we believe EBITDAX 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
    EBITDAX 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. EBITDAX 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 EBITDAX. While we have disclosed our EBITDAX to
    permit a more complete comparative analysis of our operating
    performance and debt servicing ability relative to other
    companies, investors should be cautioned that EBITDAX as reported
    by us may not be comparable in all instances to EBITDAX as
    reported by other companies. EBITDAX 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.
