I went underground here a few times in 1989, just before Minworth (then owners) went bust. The actual mine workings were quite deep - then working the 340 level - though they had plans to go down to the Whin Sill. I have no idea how much deeper they got to before it was finally abandoned in 1999. It would appear that the wrecked buildings that housed the mine offices and change house have been cleared away.
