Prestigious Papermaker in Asia to Adopt High-Filler Technology that Provides Significant Cost Savings in Reduced Fiber Consumption ----------

NEW YORK, July 24-Minerals Technologies Inc., (NYSE: MTX) announced today that it has entered into a commercial agreement with another leading Asian papermaker to provide FulFill(TM) E-325 higher filler technology.

Minerals Technologies now has nine agreements with paper mills that have adopted the FulFill(TM) E-325 technology that the company introduced in late 2010. The company has six agreements with paper companies in Asia; one with a papermaker in North America; and two in Europe. These agreements confirm the commercial progress of the FulFill(TM) brand, a portfolio of high-filler technologies that offers papermakers a variety of efficient, flexible solutions that decreases dependency on natural fiber and reduces costs. The FulFill(TM) E-325 series allows papermakers to increase loading levels of precipitated calcium carbonate (PCC) by three to five points, which replaces higher cost pulp, and increases PCC usage between 20 to 30 percent. The company is also actively engaged at more than 25 other paper mills, with paper companies from around the world that are interested in this new technology.

"We are very pleased that this prestigious Asian papermaker, who wishes to remain unnamed for competitive reasons, has elected to adopt our FulFill(TM) E-325 technology," said Joseph C. Muscari, chairman and chief executive officer. "This agreement, our ninth, substantiates the value of our FulFill(TM) portfolio of technologies and the revitalization of our new product development pipeline."

PCC is a specialty pigment for filling and coating high-quality paper. By substituting PCC for more expensive wood fiber, papermakers are able to produce brighter, higher quality paper at lower cost. Minerals Technologies originated the satellite concept for making and delivering PCC on-site at paper mills and the concept was a major factor in revolutionizing North American papermaking from an acid to an alkaline-based technology. Minerals Technologies constructed its first PCC satellite plant in 1986. Today, the company has 56 satellite plants in operation or under construction around the world and continues to lead the industry with consistent quality and technical innovation.

Minerals Technologies Inc. is a global resource- and technology-based growth company that develops, produces and markets worldwide a broad range of specialty mineral, mineral-based and synthetic mineral products and related systems and services. The company recorded sales of $1.04 billion in 2011.
