The Montpelier plant mines Aplite, formed from igneous rock deposits that are unique to this location. Our surface mines in Montpelier use fuel oil and electricity to produce Aplite through hard rock mining. The reserves are part of an igneous rock complex that is unique to this location. The Aplite processed at the Montpelier plant is utilized by the container glass, insulation fiberglass and recreational sand industries.
In 1993, U.S. Silica acquired the plant and has since invested over $3 million in improvements to the facility and equipment for silica production. Since acquiring the facility, we have renovated and upgraded its production capabilities to enable it to produce multiple products through various processing methods, including hydraulic crushing and sizing, washing, fluid bed drying and grinding.
The facility is located approximately 20 miles northwest of Richmond and is accessible by major highways including U.S. Interstates 64 and 95.
