Vintage radioactivity

A friend has just emailed me this link. I could never have dreamed that anything like this existed.

It can sometimes be a surprise wot's in rocks, down here pitchblende was the most notable, Trenwith Mine (a la Madam Curie) and South Terras were the two main sources, Trenwith is now mainly a car park, South Terras was still accessible, last time I was around there, don't venture in though the geiger count will go mad....

Talking of the mines, this has just flagged up, looks like a bloke I know is in one of the shots:

The radioactive sources decay in a period of from 1 to 50 years, it says on he leaflet... About time to send in the coupon to order spares then!

I like the mine shaft (well, not right there obviously!), what a super, straight-sided shaft to have made all those years ago!

Yes, nice shaft, probably not an air shaft, they tended to be circular, more than likely a pumping shaft, might have been an engine close by, that's my mate in some of the pictures, there's thousands of shafts down here, most covered over years ago with timber, railway sleepers or railway crossing timbers used to be the favourite, back fill then flog to a developer. I reckon that shaft was known about by someone when that site was developed.

Not sure to be honest Gary, they would have to read the small print, mining searches are the norm down here now for anyone buying a property with borrowed funds, there are basically two roads, researching records and then if required a full drilling survey, most of the records used by the mining search companies are held at the County Records Office and can be viewed by anyone for free, drilling under or around properties is a specialist job, my mate in the pictures does both, researches and drills.

The ground not far below the collar in that shaft looks good to me, if they do anything with it they will probably dig down and bench out at the good ground, build a sollar then fill with concrete.

When I was at university (many years ago), my then girlfriend was an economic geologist - in the holidays, she worked for CSM (Camborne School of Mines) (she was from that part of the world) surveying old workings - our summer days were spent investigating & logging the condition of old shafts and adits - there are thousands of them - the earliest go back to 2,000 years BC - many are not officially recorded.

I was always attracted by the nice crystals, but she just liked the dull minerals...

Ah......CSM, a well respected outfit known throughout the mining world, when I was mining down South Crofty a fair few CSM students came down to work in there during the summer hols to gain a bit of practical experience.

Used to have a half decent mineral collection Nick, all sourced from down the mine or from the old mining dumps, did you get to going in/down any of the old adit's/shaft's?   Cligga used to be a favourite one, and still is to this day.
