ITEM 5. OTHER EVENTS.

     On March 17, 2004, Contango Oil & Gas Company (the "Company") announced
that two affiliated companies bid on 37 blocks and were the apparent high
bidders on 24 blocks offered at the Central Gulf of Mexico Lease Sale #190 held
March 17, 2004 in New Orleans. Each of these blocks is located on the shelf of
the Gulf of Mexico in water depths of less than 200 meters. An apparent high bid
("AHB") gives the bidding party propriety in award of offered tracts,
notwithstanding the fact that the Minerals Management Service ("MMS") may reject
all bids for a given tract. The MMS review process can take up to 90 days on
some bids. Upon completion of that process, final results for all AHBs will be
known.

     Contango's 33% owned affiliate, Republic Exploration LLC ("Republic"), had
the AHB on 16 lease blocks with bids totaling approximately $5.6 million.
Contango's 67% owned affiliate, Contango Offshore Exploration LLC ("COE"), had
the AHB on five lease blocks with bids totaling approximately $3.5 million.
Republic and COE, bidding jointly, had the AHB on three lease blocks with bids
totaling approximately $452,000. In addition, Contango's affiliates, Republic
and COE, will share a reversionary carried working interest in Vermilion 154,
which was an AHB at Lease Sale #190. If these blocks are awarded, Contango will
own interests, both directly and indirectly vis-a-vis its affiliates, in 41
federal lease blocks in the Gulf of Mexico, covering approximately 202,200
acres.

     A copy of the Company's press release, dated March 18, 2004, regarding this
filing is attached as Exhibit 99.1 hereto and is incorporated herein by
reference.
