EXHIBIT 99.1

AMCOL International Corporation Announces Amended Merger Agreement with Imerys

Agreement Increases Price Per Share for AMCOL Shareholders to $42.75

HOFFMAN ESTATES, Ill., Feb. 26, 2014 /PRNewswire/ — AMCOL International Corporation (ACO) (“AMCOL” or the “Company”) today announced that its Board of Directors has unanimously approved an amended merger agreement with Imerys S.A. (“Imerys”), pursuant to which AMCOL shareholders will receive USD $42.75 per share in cash, an increase of $1.75 per share, for each share of AMCOL common stock that they own, without interest. The $42.75 per share consideration represents an approximately 24.5% premium to the volume weighted average closing price of the Company’s common stock over the last 30 trading days through February 11, 2014, the day prior to the announcement of the original transaction. The transaction is valued at approximately $1.61 billion, including AMCOL’s net debt.

Pursuant to the amended merger agreement, Imerys has agreed to increase its tender offer for 100% of AMCOL’s outstanding shares to $42.75 per share in cash. Imerys’ tender offer remains subject to customary conditions, including the tender of a majority of AMCOL’s total outstanding shares of common stock and shares issuable under equity awards, and clearance from antitrust regulatory authorities. The transaction is not subject to any financing condition and is expected to close in the first half of 2014. The AMCOL Board of Directors unanimously recommends that shareholders tender their shares into Imerys’ tender offer.

AMCOL also announced that its Board of Directors, after careful review and consideration with its financial and legal advisors, compared the relative merits of the previously announced proposal from Minerals Technologies, Inc. (MTX) to acquire AMCOL for $42.50 per share in cash to the increased offer reflected in the amended merger agreement with Imerys and unanimously determined that the latest Minerals Technologies proposal is not superior to the terms of the amended merger agreement with Imerys.

Ryan McKendrick, Chief Executive Officer of AMCOL, commented, “We are pleased to offer even more value to our shareholders through the amendment of our merger agreement with Imerys. We are excited about the significant opportunities this transaction will create for our employees and customers, and we share Imerys’ commitment to the successful completion of the combination to create a global leader in mineral-based specialty solutions.”

Goldman, Sachs & Co. is serving as exclusive financial advisor to the Company and Kirkland & Ellis LLP is serving as counsel to the Company.
