Great video. Loved the explanations.

I love your work.

As we Cornish know, "Hard rock makes hard men." Kernow Kensa.

Ive learned more from this video than i did from a recent trip to the mine itself. Thank you.

The walls of the tunnel seem to be red coloured - would you know if that is Devonian Old Red Sandstone?

Another Uranium mine up here in Devon..

As a fellow geologist, this was a really good explanation, in an amazingly short video.

My grandfather William Woolcock worked at Geevor. ..died in 1914..buried in St Just Methodist church graveyard

Excellent. Thank you.

Quality video, thank you

Good topic. Poor video.

I wish you did more like it

Excellent

You really shouldnt be tappin on the rock like that .....An I hope you left a bit of summat down there my boi! !

Is there anyone willing to inform the vendor of the tin ore beneficiation technology for the mine?... please email to andrian@pttimah.co.id

it is really interesting,and thought provoking.the video is highly educative .chemical analysis should have also been more importance

How many slave's might have died in there??

Next time, use the mouse the point at the things you are referring to in the video. As a beginner, it is quite difficult.

I like the famous chunk of Liroconite best. I would visit the museum more often if it was cheaper to get in.

The levels seen on his scintillator are safe <200CPM. Is this more ignorance of the science, creating unnecessary hysteria?

Collecting radioactive minerals is safe as long as you use common sense and do your due diligence on how to properly store them. ie: not in living areas of the home.

Dougal Jerram is a great communicator and this is a fantastic series of talks. Thanks.

My family worked here and lived in Pendeen..My uncle was made redundant in the late 80's

Nice video Simon, I have measured the 60 degree angles on amphiboles plenty of times, but how do they get the 120 angle? This has confused me for a long time I hope you can clear it up. Amphiboles at 60 and 120

Great video, and well presented.

I watched this entire video and I saw no cleavage

If tin prices rise again, would mining in Cornwall become profitable?

Great video, you dug deep for the puns in the title! And the pasty looked good too. Particularly enjoyed the sound track, and the history of this industry that did so much to provide the wealth that Cornwall once enjoyed.

It is more polished than mine - asktherockdoc on RU-vid.

OK I can hear the radio in the background which is weird, I couldn't hear it when I was recording...

excellent video! :)

Thanks Simon. I had no idea. My father, also a Rashleigh, carries mineral samples around in his suitcase to this day. I was born in Cornwall and been back a number of times but never checked out the Rashleigh collection. Something on the list to see, and I'm also curious to work out if we descend from Philip
