About DE floor!
I know someone whoe's been there, not me, anyone knoe it's exact length? 😉
dunno, it's about 20 mins walk one end t'other. Used to be a lot longer until a retaining wall blew out (caused by untopping from above). The original adit has long since been quarried away but I have a nice picture of it taken in the 1950's.
What we call DE floor today is only the New Vein Level, there is a matching level (that we've never touched) in the Old Vein, and possibly also Back Vein and Narrow Vein. DE Floor really is (was) a whole floor, rather than just one level, and only half of that we can get to today 😞
