Minerals Technologies Announces an Agreement with Sun Paper Group to Deploy its NewYield(TM) Integrated Process Technology in China

Generates Savings for Papermakers by Eliminating the Need to Landfill the Waste Product

NEW YORK, NY, August 11, 2014-Minerals Technologies Inc. (NYSE: MTX) announced today that it has signed an agreement with Sun Paper Group to deploy the newly introduced NewYield(TM) Integrated Process Technology at Sun's pulp and paper operations in Shandong Province, China.

NewYield(TM) Process Technology is a breakthrough technology that converts a paper and pulp mill waste stream into a functional pigment for filling paper. NewYield(TM) process technology eliminates the cost of environmental disposal and remediation of certain waste streams to papermakers. The facility, which will be operational in the third quarter of next year, will produce 60,000 tons of filler pigment from Sun's waste stream.

"We are extremely pleased to be working with such a fine papermaker as the Sun Paper Group, which is the largest privately owned paper business in China, to deploy our NewYield(TM) technology at their papermaking operations in Shandong Province," said Joseph C. Muscari, chairman and chief executive officer. "This technology provides papermakers with both cost savings and reduced environmental impact, while at the same time providing them with a filler pigment for their paper."

By utilizing Minerals Technologies' NewYield(TM) Integrated Process Technology, papermakers can eliminate the costs associated with landfill disposal or energy, and in return will receive a filler pigment that can be used in papermaking. MTI and the papermaker will both benefit, as will the environment.

New York-based Minerals Technologies Inc. is a 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.
