In the early 20th century, approximately 6 million metric tons of copper ore were mined from numerous deposits located along the shorelines of fjords and islands in Prince William Sound, Alaska. At the Beatson, Ellamar, and Threeman mine sites (fig. 1), r
This dataset is a collection of major coal mine production located in The Peoples Republic of China. Included in this dataset are the locations of major coal mines and the approximate annual amount of coal mined annually in millions of metric tons.
This is a spatial database that delineates mining-related features in areas of historic and active phosphate mining in the core of the southeastern Idaho phosphate resource area. The data has varying degrees of accuracy and attribution detail. The breakd
An environmental impact study is done for the abandoned Ely copper mine. The extent of contamination is studyed along with the type and chemical composition of the mine waste piles.
Permits to explore for and (or) develop mineral resources on Federal lands can be used to indicate locations and types of mineral-related activities on national forests. Permits for these activities require filing of a Notice of Intent to conduct mineral
