REPORTS 18% INCREASE IN DILUTED EARNINGS PER SHARE FROM CONTINUING OPERATIONS

ARLINGTON HEIGHTS, IL., JULY 18, 2008—AMCOL International Corporation (NYSE:ACO) today reported 2008 second-quarter income from continuing operations of $17.9 million or $0.58 per diluted share, compared with $15.3 million or $0.49 per diluted share in the same prior-year period.

Net sales from continuing operations rose 28.2% to $233.8 million for the quarter ended June 30, 2008, compared with $182.5 million for the 2007 period. Acquisitions and favorable foreign currency translation represented approximately $8.7 million and $5.4 million, respectively, of the second-quarter sales growth. Operating profit increased by 22.5% over the 2007 period to $23.5 million. Acquisitions added $1.4 million to current-period operating profit while foreign currency translation contributed $0.8 million.

For the six-month period ended June 30, 2008, income from continuing operations was $26.5 million, or $0.86 per diluted share, compared with $26.1 million, or $0.84 per diluted share in the prior-year period. Net income for the six-month period ended June 30, 2008, was $26.5 million, or $0.86 per diluted share compared with $25.8 million, or $0.83 per diluted share in the prior-year period, reflective of a $0.01 charge for discontinued operations that occurred during the second quarter of 2007.

Net sales from continuing operations for the six-month period ended June 30, 2008, rose 22.8 % to $425.3 million, compared with $346.2 million for the 2007 period.

This release should be read in conjunction with the attached unaudited condensed consolidated financial statements. Further discussion of items and events impacting earnings are included later in this press release.

“We had strong revenue growth across all of our reporting segments this quarter” says Larry Washow, AMCOL President and Chief Executive Officer. “Operating profit grew as well, particularly in Oilfield Services and Environmental. However, it was another quarter where we saw significant energy price increases impacting our margins.”

“In spite of the ongoing cost issues, the Minerals segment did deliver gross and operating margin improvement compared to the first quarter of 2008.” Washow continued, “We are not at all satisfied with the results, but even with the difficult operating environment we are seeing a positive trend that we expect will continue.”

“Also compared to last quarter, the Environmental segment experienced strong growth due to the seasonal nature of its business,” Washow stated.

“Oilfield Services benefited from the strong market conditions as well as a mid-quarter acquisition, which is already a positive contributor. Second quarter results show overall sales growth of 63.5%, generating a 77.7% operating profit improvement,” Washow added.

“Costs are an ongoing issue as we saw overhead spending increase primarily due to benefits and IT costs, plus additional expenses related to acquisitions. We have also increased our R&D spending,” Washow concluded.

STATEMENT OF OPERATIONS HIGHLIGHTS:

Net sales: The following details the consolidated sales growth components over the 2007 second quarter:

Minerals: Freight pass-through revenue accounted for approximately one-fourth of the base business growth, principally from the pet products and metal castings divisions. Base business sales were driven by demand in the Asia-Pacific metal casting market and certain specialty materials product lines, notably from customers in South Africa and China, in addition to price increases in U.S. metal castings and basic materials divisions.

Sales from acquisitions were contributed by our operations in Turkey and Mexico.

Environmental: Base business growth in building materials division shipments and installation services in Western Europe and Poland as well as higher shipments in lining technology product lines in the U.S. market contributed to the increase in the quarter.

Oilfield Services: Demand for domestic water treatment services in the Gulf of Mexico was the largest contributor to base business growth. Emerging markets in West Africa and Malaysia represented approximately 28.6% of the revenue growth. The Premium Reeled Tubing (“PRT”) acquisition added $3.5 million of revenue in the quarter.

Transportation: Traffic levels increased over the prior-year quarter due to higher demand from consumer products shippers.

Gross profit: Sales growth provided the increase in gross profit; however, gross margin was 26.8%, a 50 basis point decline from the 2007 quarter.

Minerals: The gross margin decline is primarily attributed to rising energy costs and increases in production and mining costs, principally in the U.S., where pricing initiatives reduced the impact of these cost increases on gross margin.

Environmental: Gross margin was comparable to the prior-year quarter.

Oilfield Services: Gross margin improved 110 basis points over the prior quarter due to improved pricing, product mix, emerging markets growth and the acquisition of PRT.

Transportation: Gross margin declined 120 basis points principally due to unrecovered fuel surcharges.

General, selling and administrative expenses (GS&A): GSA expenses increased $8.6 million, a 27.9% increase over the 2007 second quarter. Expenses in each segment increased, with Oilfield Services experiencing the largest increase due to overall growth of the business, entering emerging markets and the acquisition of PRT.

Minerals: Base business GS&A grew due to increased research and development expenditures for the specialty materials division and personnel costs in the Asia-Pacific region.

Environmental: GS&A increased primarily due to increased compensation and sales commission expenses at the Poland-based operations.

Corporate: GS&A increased $2.1 million due to increasing benefits costs and IT expenses resulting from infrastructure investments.

Page 4 of 12

Operating profit: The increase over the prior-year quarter was primarily caused by the combined effect of the gross profit improvement somewhat offset by increases in GS&A costs, especially in our Corporate segment, which drove the 50 basis points decrease in operating margin.

Interest expense: Net interest expense increased by approximately $0.7 million over the prior-year quarter due to higher average debt levels.

Other, net: The increases represents a currency hedge gain on a position in the Australian dollar for our pending South Africa chrome mine investment, offset by other foreign currency fluctuations and minority interest.

Income taxes: The effective tax rate for the second quarter of 2008 was 26.8% compared with 24.7% for the same period in 2007. This is due to increased operating profit in the U.S., which has higher tax rates than international operations.

Income from joint ventures: Income from our India based investments remained relatively consistent versus prior periods.

Share count: Weighted average common and common equivalent shares outstanding were 31.0 million and 30.9 million for the quarters ended June 30, 2008 and 2007, respectively.

FINANCIAL POSITION AND CASH FLOW HIGHLIGHTS:

Long-term debt increased to $249.5 million at June 30, 2008 compared to $164.2 million at December 31, 2007.  The increase was primarily due to funding acquisitions, increased working capital levels and capital expenditures.Total long-term debt represented 40.6% of capitalization at June 30, 2008, compared with 31.8% at December 31, 2007.  Cash and cash equivalents were $22.0 million at June 30, 2008 compared with $25.3 million at December 31, 2007.

Working capital increased to $250.3 million at June 30, 2008 from $202.5 million at December 31, 2007.  The current ratio was 3.1-to-1 and 3.0-to-1 at June 30, 2008, and December 31, 2007, respectively.

Cash flow used in operating activities was $2.0 million year-to-date as of June 30, 2008 compared to $25.6 million cash being generated in the prior-year period.  The increase in working capital caused the decline in operating cash flows compared with the prior-year period, principally due to a greater increase in accounts receivable of $24.7 million.

Excluding the corporate building, acquisitions were the primary investing activity in the 2008 period amounting to $42.3 million, largely due to the PRT acquisition compared with $38.4 million in the prior-year period.  Capital expenditures in the 2008 period amounted to $23.3 million compared with $21.0 million in the prior-year period.

Approximately $2.0 million has been expended on share repurchases thru June 30, 2008, with $6.6 million remaining under authorization.  Eighty thousand shares were repurchased at an average price of $25.45 per share.  Dividends declared year-to-date through June 30, 2008, increased by 15.2 % over the prior-year period to $9.7 million.
