Cowboy Mining Company is the bentonite mining, processing, and packaging division of PDSCo, Inc. Our bentonite mine is located in Southwest Texas, near Big Bend National Park. We surface mine high quality sodium bentonite and further process the material into granular, chips, pellets and powder for a variety of applications. The mining and processing operations are controlled by stringent quality control procedures. The bentonite products produced at our facility have been NSF certified. Independent laboratories have conducted extensive testing and analyzed the properties of the bentonite we are mining and have found them to equal the quality of the bentonite mined in Wyoming.
