The district round Lustleigh, near Bovey Tracey, is mined on a small scale for a very fine quality of micaceous haematite, which occurs there in well-defined lodes traversing the granite. This soft and powdery variety of haematite, known both locally and in the trade as ‘shining ore’, is used for a variety of purposes, but principally as the basis of a rust-proof paint. The ore and its mode of occurrence have been briefly described by J. S. Martin, and for the purpose of this short paper no fm4her description of the mines in general will be necessary.
