                                                           FOR IMMEDIATE RELEASE

                                                                    May 13, 1998

                "SOUTHERN & NEUTRINO SIGN ACQUISITION AGREEMENT"

HOUSTON -- Southern Mineral Corporation (NASDAQ:SMIN) of Houston and Neutrino
Resources, Inc. (Toronto Stock Exchange:NTO) of Calgary announce that they have
signed a definitive agreement for the acquisition of Neutrino by Southern for
cash consideration of Cdn. $1.80 per share. Total cash consideration is
estimated to be U.S. $40 million (Cdn. $57.4 million). In addition, Southern
would be assuming Neutrino's bank debt and working capital deficiency, which was
approximately Cdn. $21.5 million as of March 31, 1998 (U.S. $15 million).

The transaction has been approved by the Board of Directors of both companies.
Southern has indicated its desire to retain the current employees and management
of Neutrino. The definitive agreement embodies a lock-up arrangement with
officers, directors and significant shareholders. Neutrino has agreed to a
breakup fee representing 5% of the total consideration available to
shareholders. Closing is scheduled on or before June 30, 1998.

Based on independent engineering evaluations, Neutrino's total proved reserves
as of January 1, 1998 were 37.4 billion cubic feet of natural gas and 6,146,000
barrels of oil and natural gas liquids for a total of 74.3 billion cubic feet
equivalent (oil and liquids are converted to gas at 6,000 cubic feet for each
barrel). The proposed transaction would increase Southern's total proved
reserves by 78% from an end of the first quarter internal estimate of 94.8
billion cubic feet equivalent to 169 billion cubic feet equivalent.

During the fourth quarter of 1997, Neutrino produced an average of 12.4 million
cubic feet of natural gas and 2,020 barrels of oil and natural gas liquids per
day for a total of 24.5 million cubic feet equivalent of daily production. The
proposed acquisition would increase Southern's daily production to more than 50
million cubic feet equivalent.

The proposed acquisition of Neutrino also increases Southern's undeveloped land
holdings in Canada by more than 400% from 14,695 net acres to 74,670 net acres.
Neutrino also holds an extensive data base of two and three dimensional seismic.
