The natural elements are generally rare at Franklin and especially so at Sterling Hill; they were not utilized economically, and few studies have been done. At Franklin, lead is usually finely-dispersed, and copper occurs as both finely-dispersed platelets and coarsely-crystallized masses, the latter well-represented in systematic collections. Graphite is abundant in the Franklin Marble, but generally not in the orebodies. The locally occuring natural elements are listed below.
