The company conducted exploratory drilling last year to determine the quantity and quality of the wollastonite located on the state land in question.

The company, a major employer in the region, operates two wollastonite mines in Essex County, including one next to the Jay Mountain Wilderness.

Secondary mica is also a common result of alteration, and among other products are pinite, epidote, saussurite, chlorite, wollastonite and various zeolites.

The Liassic beds are often metamorphosed and the limestones contain garnet and wollastonite.
