Don't have a map, but might have something else you might find
interesting... will contact off List.
Re the other mine you mention, this is the Red Dragon mine I think? A rather
dubious gold venture, that only managed to loose a quantity of mercury in an
accident. If we are talking about the same place I have been u/g there, and
it is not very safe! - air somewhat dubious as well due to the rotting shale
(and gnrl. lack of vent.).
