(NYSE: MTX) will be implementing price increases for ground calcium carbonate, precipitated calcium carbonate, and lime products used in non-paper applications. These increases will range from 5 percent to 15 percent and will be applied to products manufactured at SMI's North American manufacturing facilities in Adams, Massachusetts; Canaan, Connecticut; and Lucerne Valley, California. These price increases are necessitated by a number of factors, including the cost of mining, processing, packaging and shipping, which have caused SMI's product costs to escalate at rates that significantly exceed historical norms.
