I was idly browsing the trip reports on this forum looking for some info on Hanging Flat mine in Stoney Dale when I came across a report by Alan Brentnall from 2016: https://www.tsgcaving.co.uk/content/Trip-Reports/stoney-middleton-alan-brentnall
The report made mention of a WW2 aragonite mine above the small caves on the southern side of the Dale near the Horseshoe Quarry parking area.
