New rates in effect as of June 1, 2019

RENO, Nev.–(BUSINESS WIRE)–EP Minerals, LLC, a U.S. Silica company and global leader in industrial

diatomaceous earth powder, perlite, bleaching clay, adsorbent and
cellulose products, or will do so as existing contracts allow. The
increase will be applied in North America and South America. The price
increase is necessary to offset inflationary pressure with the rise in
