Chesapeake Minerals

Chesapeake Minerals is a division of Stewart Companies, a mid-Atlantic-based group of diversified businesses that employs over 1300 people across multiple markets. The Stewart Companies have active mining operations in Maryland, Pennsylvania and Colorado, where sand, gravel and stone production exceeds 3.2M tons annually. Chesapeake Minerals uses select grades of quartz gravel supplied by York Building Products' adjacent Belvedere plant where more than tons of alluvial sand and gravel are processed daily. Select quartz gravel is crushed, washed and classified into multiple low-iron, high-purity quartz commodities. Two grinding mills were recently added to the circuit and commissioned ito produce high purity silica powders to customer specification.
