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.
I visited recently, there's a laboratory on site, it's called The Sample House, it's where the Ore is analysed and assayed for purity, there are about 10000 samples remaining from the day the mine closed, I highly recommend a visit
They didn't use slaves in 17th 18th century Cornish mining , if maybe you went back much further in time, 2000 years ago in Roman times , possibly the Romans might have used slaves ( the Romans came to Cornwall for Tin) .
