The Directory of the Nonfuel-Minerals in Pennsylvania is available as an Acrobat file or as an interactive web-mapping application. Both provide detailed information about the rocks being mined in Pennsylvania, the products being obtained from these rocks, and the companies that obtain them.The Nonfuel Mineral Resources of Pennsylvania.

Although once eagerly sought in the United States, uranium deposits in Pennsylvania are currently not being mined. There is more environmental concern for uranium's detrimental effects than desire for its commercial value. Deposits of uranium and thorium have been found in various parts of the state including the Reading Prong area. Uranium and Thorium analyses from this area of Pennsylvania are available. The samples were collected during a detailed study of the Reading Prong, which was completed in 1980.
