Exhibit 99.1 For further information, contact: Jennifer Melsheimer Investor Relations Manager 847/394-8730 FOR IMMEDIATE RELEASE AMCOL INTERNATIONAL (NYSE:ACO) REPORTS SIGNIFICANT GROWTH IN FIRST QUARTER EARNINGS ARLINGTON HEIGHTS, ILL., April 21, 2003--AMCOL International Corp. (NYSE:ACO) today reported first quarter net income of $2.9 million or $0.10 cents per diluted share, compared with $532 thousand or $0.02 cents per diluted share in the same prior-year period. Net sales rose 39 percent to $79.5 million for the period ended March 31, 2003, compared to $57.3 million for the period in 2002. Larry Washow, AMCOL president and chief executive officer said, "We are pleased to report an increase in sales throughout our major business divisions in both the domestic and international markets over the difficult 2002 first quarter. AMCOL demonstrated leadership in its core markets this quarter, with both our mineral and environmental groups delivering solid gains in both revenue and profit." SEGMENT DISCUSSIONS Minerals The minerals segment, which accounted for approximately 63 percent of AMCOL's consolidated net sales for the first quarter of 2003, reported a sales increase of 49 percent, and an operating profit increase of 122 percent over the prior-year period. Washow said, "Approximately 60 percent of the sales increase and 90 percent of the operating profit increase in the minerals segment was generated from our core groups outside of CSM, which was acquired in May 2002. Domestic metalcasting had a positive performance with sales volume improvement over the 2002 quarter. Our Pet Products Group saw not only increased sales over the prior year quarter, but the benefit of significant profit improvement from the ongoing restructuring at our production operations. Export shipments from the U.S. improved over a weak 2002 first quarter and we saw continued improvement in our Asian operations." MORE AMCOL Q1 2003 EARNINGS Page 2 of 7 Environmental AMCOL's environmental segment, which accounted for 30 percent of the company's consolidated net sales for the first quarter of 2003, reported a 27 percent increase in sales and a 154 percent increase in operating profit in year-over-year comparisons for the first quarter. Washow said, "Our environmental segment delivered very good results during the first quarter. Similar to minerals, we experienced improvement in sales and operating profit across a number of business units. Sales were particularly strong in the domestic and international lining technologies markets." Washow commented that the segment's strategy to globalize its business was continuing. He added, "A new production facility near Shanghai, China is on track to start-up in the first quarter of 2004. This will expand our capability for selling lining technology and building materials products in the burgeoning Chinese market." Transportation AMCOL's transportation segment, which accounted for 7 percent of the company's consolidated net sales, reported a 19 percent increase in sales, and a 66 percent increase in operating profit for the 2003 first quarter. Washow noted, "First quarter sales improved with new accounts contributing significantly to the increase. While fuel costs continue to impact results, operational cost controls yielded improved margins." Financial Overview Total short-term and long-term debt was $ 22.3 million at March 31, 2003 compared to $18.2 million at December 31, 2002. Debt represented 12.8 percent of total capitalization at March 31, 2003, compared to 10.7 percent at Dec. 31, 2002. General, selling and administrative expenses were $14.3 million in the 2003 first quarter, an increase of $2.3 million or 19 percent, over the 2002 period.

The weighted average number of common and common equivalent shares of 29.7 million decreased by approximately 1.2 million shares, or approximately 4 percent, from March 31, 2002.
