one of my best mining experiences was at Bage Mine, the w.m.r.g. run the mine and I was lowered down and allowed to wander, teriffic place. the mines research group as you say use it as their base, the amount of work they have done there is a tribute to their ability and deternmination to search the old mine. I take my hat off to them one and all. Bage is a mine I have always been interested in, living in Cromford for many years I used to wander up there and a few others nearby. I would be interested in whatever history you have please, I would pay for any costs involved. I visit Cromford 2/3 times a week so I could collect if its easier for you. Nice bit of history about your family..treasure it,add to it and pass it on to you children for safe keeping later on.
be afraid.....very afraid !!!!
