                      GFSB BANCORP, INC. ANNOUNCES EARNINGS

Gallup, New Mexico - GFSB Bancorp, Inc. (NASDAQ SmallCap:  GUPB), parent holding
company of Gallup Federal  Savings Bank,  Gallup,  New Mexico,  today  announced
earnings for the quarter ended December 31, 2004, of $327,000 ($0.27 per diluted
share) and for the six months ended  December 31, 2004,  of $801,000  ($0.67 per
diluted  share).  Earnings for the same periods a year earlier were $500,000 and
$827,000.

The $26,000  decrease in earnings for the six months ended December 31, 2004 was
primarily  the result of a  $332,000  increase  in  non-interest  expense  and a
$141,000  increase  in income tax  expense,  partially  offset by an increase of
$312,000 in net interest earnings, a $64,000 increase in non-interest  earnings,
and a $70,000  decrease in provision for loan losses.  The decrease in provision
for loan losses for the current six-month period is primarily due to improvement
in loan quality and the fact that the Company's loan portfolio  decreased during
the period.

The increase in net interest  earnings was primarily due to a $460,000  decrease
in total  interest  expense  partially  offset by a $148,000  decrease  in total
interest   earnings.   The  increase  in   non-interest   expense  is  primarily
attributable to significant  increases in legal and  professional  services fees
associated  with the Agreement and Plan of Merger  between the Company and First
Federal Banc of the Southwest, Inc. announced on August 25, 2004.

The $64,000  increase in  non-interest  earnings  for the  six-month  period was
primarily  due to an increase in service  charge  income of $87,000 and a $5,000
increase  in income  from real  estate  operations  coupled  with a decrease  of
$29,000  in  miscellaneous  income.  The  decrease  in  miscellaneous  income is
primarily  attributed  to gains on the sale of other  real  estate  owned in the
year-ago period.

At December 31, 2004, the Company's capital to asset ratio was 8.8%, with assets
and stockholders' equity of $217.3 million and $19.1 million, respectively.
