Agreement with CMPC Celulose Riograndense to Deploy FulFill(TM) Technology at
                            a Paper Mill in Brazil

  Unique High-Filler Technology Provides Significant Cost Savings in Reduced
               Fiber Consumption by Increasing PCC Filler Usage
  First Commercial Agreement for the FulFill(TM) Technology in South America

NEW YORK, March 13-Minerals Technologies Inc., (NYSE: MTX) announced today
that it has signed a commercial agreement with CMPC Celulose Riograndense to
provide Fulfill(TM) E-325 at a paper mill in Guaiba, Brazil. This marks
Minerals Technologies' first such agreement in South America for the new,
high-filler technology.

The company now has 13 agreements with paper mills that have adopted the
Fulfill(TM) E-325 technology introduced in late 2010, which verifies the
technology's commercial progress. The FulFill(TM) brand offers papermakers a
variety of efficient, flexible solutions that 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 this premier paper company, with which we have been
supplying PCC at Guaiba since 2007, will adopt our new FulFill(TM) technology.
FulFill(TM) will provide CMPC a competitive advantage and allow them to
continue producing quality paper but at a lower cost," said Joseph C. Muscari,
Executive Chairman of Minerals Technologies. "We now have commercial
agreements with papermakers in Asia, Europe, South Africa and North and South
America, which validates the revitalization of our Research and Development
pipeline and our commitment to advance our technology leadership throughout
our global satellite network."
