A chromite mine located on the state line between Pennsylvania and Maryland, located in both Fulton Township, Lancaster County Pennsylvania and Cecil County Maryland. The Discovery shaft located in Pennsylvania gave access to a stringer of massive granular chomite in serpentine rock. Open pit mining was conducted in the area stradling the state line, with underground working extending into Cecil Co., Maryland. Active mining ceased in 1919.
