Although NYCO’s facilities span one continent, the impact of our wollastonite products is felt the world over.

Through a combination of experience and innovation, NYCO's two impressive operations make it the origninal and leading producer of premium quality wollastonite worldwide.

NYCO Minerals, Inc

Established in 1953, the Willsboro operation is situated in the Adirondack Mountains of New York, U.S.A.. It is world-renowned for its highly acicular ore and advanced processing and surface modification techniques.

Minera Roca Rodando S.
de R.L. de C.V.
(Pilares Operation)
Opened in 1997 in Hermosillo, Sonora, Mexico, Pilares is the world's largest capacity wollastonite mine and processing facility.

Surface modified and untreated products are available from both operations. Equivalent grades are offered from each site as are products unique to the deposit from which they originate to give our customers the breadth of choices that are required.

Products are shipped from both locations in a variety of packaging alternatives via truck, rail or water to our worldwide customers.

Each site is staffed with specialists to manufacture quality wollastonite products and help our customers take full advantage of the potential these products have to offer.
