Minerals Technologies Inc. Signs Commercial Agreement with Mondi PLC to Deploy FulFill(TM) E-325 Technology for High-Filler Loading at a Paper Mill in Slovakia

Unique High-Filler Technology Provides Significant Cost Savings in Reduced Fiber
Consumption by Increasing PCC Filler Usage
 ----------

NEW YORK, July 2-Minerals Technologies Inc., (NYSE: MTX) announced today that it
has signed a commercial agreement with Mondi SCP a.s., a subsidiary of the Mondi
Group, to provide Fulfill(TM) E-325,  a new, high-filler technology,at the paper
company's paper mill in Ruomberok, Slovakia. This marks Minerals Technologies'
first such agreement in Europe.

The company now has seven agreements with paper mills that have adopted the
Fulfill(TM) E-325 technology that the company introduced in late 2010. 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), which replaces higher cost pulp, and
increases PCC usage.

"We are very pleased that Mondi will adopt our new FulFill(TM) technology, which
will allow them to continue producing quality paper but at a lower cost," said
Joseph C. Muscari, chairman and chief executive officer of Minerals
Technologies. "The seven commercial agreements we now have with papermakers
around the world reaffirms the revitalization of our new product pipeline and of
our commitment to advance our technology leadership throughout our global
satellite network."

Mondi's key operations are located in central Europe, Russia and South Africa.
The company employees 23,400 people across 28 countries worldwide. Mondi SCP is
one of the key mills of Mondi's Europe & International Division. More than 77
percent of its production can be identified as "green" since energy used for its
production comes from biogenic resources, while wood comes from certified, well-
managed forests.

PCC is a specialty pigment for filling and coating high-quality paper. By
substituting Minerals Technologies' PCC for more expensive wood fiber, customers
are able to produce brighter, higher quality paper at lower cost. In 1986,
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
papermaking in North America. 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 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.
