I m back
I am not very well but trying to stay on my feet.
False floors on no 3.
There is the obvious when you go onto Principal Lode as you come in, see the hole in the floor through the concrete. The major expanse of no 3 is devoid of any more bar the concealed ore chutes or winzes on the right. The story of the level hanging on chains is nonsense. The chains support cross rails above a quartz bed which would have pounded under the ore trucks.
Towards the end there are big holes, some covered by fallen timber, great care is needed, but I dont think there is anything you cant see if you look carefully.
Having said all of this the big holes further in do look scary.
Also keep the red water away from your skin and SRT gear, its sulphuric acid.
Parc is Parc.
