Bassett Grylls Mine, Cornwall

Bassett Grylls Mine Cornwall

Basset and Grylls Mine workings go back to at least 1574 as the Redde Worke later turned into the Ball Reeth. Basset & Grylls Mine was also known as Porkellis United. The pumping engine house at Tyacke’s Shaft was built in 1858 following the tragic flooding of an older section of the mine when water and fine-grained tin ‘slimes’ collapsed into the workings.

1858 August 24th - 7 miners were killed when a surface slimes pond collapse into the mine flooding it. This was the worse mining accident recorded in the district. The mine was one mile east of Poldark. A number of the miners had begun supplementing their income by extracting ore from an abandoned section of the mine. They carried on mining for a number of weeks, moving ever closer to the bottom of a lake. Eventually the ground gave way and the mine was flooded. Forty three men managed to escape, but seven were drowned and there bodies never recovered. Local rumour has it that one of the drowned miners kept all his savings in gold sovereigns in a belt around his waist because he did not trust his wife with his earnings. The treasure, it is said, remains at the bottom of the mine.
