CARCO Mineral Resources is a family owned and operated company focusing on complete customer satisfaction by providing quality products, excellent service, technical support, and competitive prices.
CARCO provides local in-house testing as part of a consistent quality assurance program. This program ensures that before each ton is packaged, it has been thoroughly examined to meet customer specifications. The Caldwell Plant performs in-process tests and final product testing for each ton before every shipment.
Producing the highest quality products at CARCO requires responsible stewardship to land and environment, strategic planning, continuous operational improvements and ongoing testing to ensure the quality our customers deserve. Quality Control is a way of life at CARCO!
While lab testing at the Caldwell Plant focuses on Grit Analysis, Moisture, pH, Brightness and Viscosity, CARCO exercises other analysis to assure consistency for each product line. CARCO will use independent laboratories for accountability, further analysis and product development.
