                      COMPASS MINERALS INTERNATIONAL, INC.
              ANNOUNCES FOURTH-QUARTER AND FULL-YEAR 2004 RESULTS

         OVERLAND PARK, Kan. (February 7, 2005) - Compass Minerals
International, Inc. (NYSE: CMP), a leading producer and marketer of salt and
specialty potash, reported the following fourth-quarter and year-end results:

         -        Fourth-quarter sales increased 17 percent over the prior
                  year.

         -        Full-year sales were $695.1 million, a 16 percent increase
                  over 2003.

         -        Fourth-quarter net income was $19.9 million or $0.62 per
                  diluted share. The company incurred a charge of $0.4 million
                  for a secondary offering of common stock by Apollo Management
                  LP and other stockholders. Upon completion of their ownership
                  exit strategy, Apollo terminated its management consulting
                  agreement with Compass for which the company incurred a
                  one-time pre-tax charge of $4.5 million.

         -        Excluding these special items, net income for the quarter was
                  $23.1 million or $0.72 per share.

         -        Full-year net income was $49.8 million, or $1.57 per diluted
                  share, including a partial release of the company's tax
                  valuation allowance in third quarter, secondary offering
                  costs in second and third quarters, and the special items
                  mentioned above. Excluding special items, full-year net
                  income was $42.9 million, or $1.35 per share.

         "We set new sales and EBITDA records in 2004, and we've posted eleven
consecutive quarters of year-over-year revenue increases. I believe these
results are a testament to our organization-wide focus on increasing sales,
improving productivity and containing costs," commented Michael E. Ducey,
Compass Minerals president and CEO. "We're optimistic about the outlook for the
first quarter of 2005. We've had favorable winter weather in our service area
and, thus far, highway and consumer deicing salt sales are keeping pace with
the record sales we posted in the first quarter of 2004."

         For the quarter, salt sales increased 12 percent over the prior year
to $210.1 million. Sales of highway deicing salt benefited from stronger sales
in the U.K. and moderate sales volume increases in the company's northern
markets in North America. General Trade sales increased over the fourth quarter
of 2003 due to slightly higher water conditioning and consumer deicing sales,
organic market growth and modest shifts in product mix. Salt sales also reflect
a $5.3 million foreign exchange benefit.

         Salt sales for the full year were $607.5 million, an 11 percent
increase over 2003. The growth was the result of an increase in highway deicing
commitments, strong consumer deicing sales in the first quarter, price
improvements and moderate base-business volume gains in both product lines.

         Fourth-quarter sulfate of potash (SOP) sales were $25.9 million, a 69
percent increase over the prior year. The quarter-over-quarter sales
improvement was the result of a 62 percent increase in tons sold as well as
previously announced price improvements.

         Full-year SOP sales of $87.6 million were 62 percent higher than in
2003 primarily due to the company's efforts to expand the SOP market and
Compass's December 2003 acquisition of an SOP marketing business.

         Selling, general and administrative expenses increased by $3.9 million
to $18.6 million for the quarter reflecting increased variable compensation and
selling expenses, higher professional services for Sarbanes-Oxley compliance
and other accounting services, and the impact of foreign exchange rates on
Canadian and U.K. expenses.

         Other expense reflects a foreign exchange loss of $2.9 million in the
quarter compared to a foreign exchange loss of $0.6 million in the fourth
quarter of 2003. Foreign exchange losses for the full year totaled $6.9 million
compared to a loss of $3.9 million for 2003. These losses are primarily the
result of intra-company transactions.

         Interest expense for the quarter was $15.7 million of which $6.0
million is a non-cash accrual for payment-in-kind interest on the company's
senior subordinated discount notes and its senior discount notes. Interest
expense for the year was $61.6 million of which $23.6 million was a non-cash
accrual for payment-in-kind interest.

         Compass recorded income tax expense of $8.0 million for the quarter
compared to tax expense of $6.1 million for the same quarter of 2003. For the
year, the company's income tax expense was $4.9 million compared to $3.3
million in 2003. In the third quarter of 2004, the company recorded a non-cash
benefit to earnings of $11.1 million as a result of the release of part of the
company's valuation allowance against deferred tax assets.

         For the year, cash flow from operations was $99.7 million compared to
$69.1 million in 2003. Capital expenditures were $26.9 million for the year
compared to $20.6 million in 2003. Compass's debt, net of issuance premium, at
December 31, 2004 was $580.4 million compared to $600.4 million in 2003. Debt
net of cash was $570.7 million compared to $597.8 million at December 31, 2003.

ABOUT COMPASS MINERALS INTERNATIONAL

         Based in the Kansas City metropolitan area, Compass is the
second-leading salt producer in North America and the largest in the United
Kingdom. The company operates nine production facilities, including the largest
rock salt mine in the world in Goderich, Ontario. The company's product lines
include salt for highway deicing, consumer deicing, water conditioning,
consumer and industrial food preparation, agriculture and industrial
applications. In addition, Compass is North America's leading producer of
sulfate of potash, which is used in the production of specialty fertilizers for
high-value crops and turf.

NON-GAAP MEASURES

         EBITDA (earnings before interest, taxes, depreciation and
amortization) and adjusted EBITDA (EBITDA adjusted for special items and other
income/expense) are non-GAAP measures. They are not recognized in accordance
with generally accepted accounting principles (GAAP) and should not be viewed
as an alternative to GAAP measures of performance. Furthermore, such measures
may not be comparable to the calculation of these measures by other companies.

         Management believes that these non-GAAP measures can assist investors
in understanding our cost structure, cash flows and financial position.
Management further believes that it is helpful to provide an analysis of our
ability to satisfy our debt service, capital expenditures and working capital
requirements in terms of EBITDA and adjusted EBITDA. The company's financial
covenants and ratios in our senior credit facilities and indentures are also
tied to measures that are calculated by adjusting EBITDA as described below.
Excluding non-recurring items from net income available for common stock is
meaningful to investors because it provides insight with respect to ongoing
operating results of the company.

- ---------
(1)      The company recorded a non-cash benefit to earnings of $11.1 million
         in the third quarter of 2004 due to the release of part of the
         company's valuation allowance for deferred tax assets. Amounts in 2003
         represent non-cash changes to the valuation allowance for deferred tax
         assets.

(2)      Pretax costs of $4.5 million were incurred when Apollo Management LP
         terminated its management consulting agreement with the company.

(3)      The company incurred pretax costs of $2.4 million in December 2003 for
         its initial public offering, and pretax costs of $0.4 million in the
         fourth quarter and $1.4 million in the full year for secondary
         offerings of common stock filed on Forms S-1 and S-3 with the SEC. The
         shares sold in each public offering were previously held by
         stockholders so the company did not receive any proceeds from the
         sales.

(4)      The company recorded an $8.2 million gain resulting from the
         repurchase of 14,704 shares of mandatorily redeemable preferred stock
         in June 2003. The gain was recorded as an increase to net income
         available for common stock.
