hi karzid, yeah I saw the shape too, it looks like a cartoon man smoking to me lol
hi JN, thanks for explaining the difference between the orbs

I did notice the blue one appears to be different, the big one I could see straight through and the other smaller one near the blue on seems to just fade away into the background when I zoom in on it.
hi buddharat, I just googled the mine and theres lots of links but Im in the middle of something so dont have time to scan the links for any deaths/hauntings etc. Funny enough the mine is called the Blue John mine and it wasnt til I clicked on the first link that it said the mine is rich in lead and something called blue john that is made into ornaments and jewellery. Maybe thats why the blue orb is so blue looking, it could maybe be an ordinary orb (by this i mean a non dust/moisture orb that is reflecting off something in the walls maybe?) I already knew the mine was called blue john mine but thought that was just a name for it, I didnt realise there was actually something called blue john ....doh
Theres a link here to the google results for the mines in case anyone has time to investigate the deaths/haunting side of it

Im definitely gonna have a look at them when I have more time.
