Have you considered that due to the extreme depth of this shaft, it too was also used to dump chemical waste FROM Nancekuke, as were many old shafts around the former RAF Portreath site where Nancekuke stood, before being decommissioned when it was found to be the environmental and health hazard it clearly had been to the community at large? Too coincidental to have a later concrete "water pump house" also built on this Dolcoath site. May also explain some of the radioactive readings...
My science teacher used to be the safety surveyor for the whole of south Croft’s mine which connects to dolcoath. He would go to work and when he was done for a day he would ride the trams to then climb out of this shaft and get to his house on dolcoath road
Such a good location for Geothermal Energy!!! This mine might only be 1 kilometre deep, but that’s still about a quarter of the work done for free, by people who lived over 100 years ago! The natural radioactivity shown, guarantees they’ll be hot rock ready to exploit. The only potential issue I see, is if the shaft is not straight? However modern, directional drilling, could still exploit a majority of the mining shafts void. Or is there a technical reason, why the geothermal going on for the Eden Project left this site alone?
Never been to that one. I'll have to go there on a clear day just for the views. It took longer to build the shaft than it was actually used for, apart from extracting the water for Nancekuke.
@@hithere4752 the dolcoath mine is measured from surface at Williams shaft south frofty Is measured from the deep adit. Dolcoath is 550fms deep South Crofty is 495 to the sump at the bottom of sub decline 2 from what I've been told. Given the adjustments for altitude and depth to adit, South Crofty is aprox 35 feet deeper. However Williams shaft is still the deepest single shaft.
Loving the video and the music mate. Right on

Fascinating video Lucas, very informative. Been there a couple of times, amazing views on a clear day. Many thanks.

Remember it well , I use to live at Rose Cottage Carn Entral,in the 60s about a half a mile up the road from here.
Absolute impossibility to visit the mine and not to drop a rock down the shaft.

How was the shaft dug? 3000 feet deep, that’s a lot of material!!
Why the music.
Great video 👍🏻
Why no 480 playback, YT seems to be deleting that watch back of 480.
Thats what I want to know when I visit a defunct mine: where are the capped shafts?
Nice sharing
They pumped the mine water to Nancekuke in the mistaken idea it was heavy water, used in the Nuclear business.
did the pumped "fresh" water have radiation in it? good video
Propper job
This is the deepest shaft in Cornwall but not the deepest mine, that would be South Crofty
south crofty is the most extensive in cornwall but not the deepest. crofty at its lowest section is still around 100 m shallower than dolcoath
Creepy place.
