There is a graphite-free zone, about 2 meters in thickness, at the contacts with both of the zinc orebodies. Graphite is commonly associated with phlogopite, other silicates, and sulfides. It is generally found in the local quarries where it may form as masses. A remarkable occurrence at the Franklin Mine was mentioned briefly by Palache (1935).

Natural graphite is a crystalline mineral of pure carbon which normally occurs in the form of platelet-shaped crystals. It has important properties, such as chemical inertness, low thermal expansion, and lubricity, that make it almost irreplaceable for certain uses such as refractories and steelmaking. Graphite ore types are crystalline (flake and lump} or 'amorphous' (cryptocrystalline}.
