Welcome to American Gilsonite Company

American Gilsonite Company and its predecessor companies have provided high-quality Gilsonite and Gilsonite products and service since 1888. Gilsonite, a registered trademark of American Gilsonite Company, is a non-hazardous, naturally occurring hydrocarbon resin that is similar in appearance to coal or hard asphalt but not similar in properties.  Gilsonite is a unique industrial mineral found only in Eastern Utah.

As the world's major supplier of Gilsonite products, we market many different grades. We have extensive experience in shipping direct from our Bonanza Mine Site and through our network of agents and stocking distributors in over 40 countries around the world.

Our products are carefully screened for impurities, dried to controlled moisture specifications, classified by particle size, held in large concrete silos until ready for final packaging, and stored in a covered warehouse prior to shipment. Our labs conduct extensive quality controls throughout the production process and every order is shipped with an individual certificate of analysis that guarantees its adherence to specifications.
For orders or additional information, please contact us directly.  We look forward to meeting your business needs. Thank you for your interest in American Gilsonite Company.
