 Second Satellite PCC Facility at a Paper Mill in Thailand Owned by Double A
                          (1991) Public Company Ltd.

NEW YORK, January 25-The Minerals Technologies Inc. (NYSE: MTX) said today
that a satellite precipitated calcium carbonate (PCC) plant announced in
October of 2011 at a paper mill owned by Double A (1991) Public Company Ltd.
in Tha Toom, Thailand, became operational in the fourth quarter of 2012.

This joint venture is Minerals Technologies' second satellite PCC plant with
Double A at the Tha Toom paper mill. This PCC facility, which will be operated
by Double A Specialty Minerals Company Ltd., will eventually produce
approximately 80,000 metric tons of PCC a year after it ramps up production.

The Tha Toom paper mill has also signed a commercial agreement for Minerals
Technologies' FulFill(TM) E-325 technology. The adoption of FulFill(TM) E-325
by Double A had been announced previously as an agreement with an unnamed
Asian papermaker.

"Our relationship with this premier papermaker, which goes back to 1996, is
further strengthened by the startup of this satellite PCC plant and the use of
our FulFill(TM) technology," said D.J. Monagle, senior vice president and
managing director, Paper PCC. "We are very pleased to further our long-time
partnership with this environmentally focused brand leader."

Double A exports its 'Double A Quality' premium copy paper to more than 100
countries and is a world leader in environmentally friendly pulp and paper
production based on the development of its Farmed Trees concept. Up to one
million Thai farm families plant fast-growing eucalyptus trees in previously
unused space between rice patties and tapioca fields to increase their income
and provide a sustainable fiber source for Double A.

PCC is a specialty pigment for filling and coating high-quality paper. By
substituting PCC for more expensive wood fiber, customers like Double A 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 57 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.
