Cassiterite and Wolframite

ID: CC976

A rich ore sample from one of Cornwall's oldest recorded Tin mines - Great Work - which was working before 1540. The specimen we have is a rich Tin-stone heavily impregnated with sparkling Cassiterite, and black sub-metallic blades of Wolframite to 1.5cm long. White areas of Fluorite are also associated with the specimen. All three minerals are embedded in a green Chlorite Matrix. An old label records that this specimen came from the abortive reopening in 1936.
