    Peter,
        Thank you for the thought of the Forest of Dean, but the iron ore
mines here are fairly unique, in that the iron ore infilled existing cave
passages, not the bedding.    The deposits are therefore not sedimentary in
the normal sense, like ironstone mines, or in a vein, as in most other metal
deposits worldwide.


        Yours in a Hole,

                Mole.
