Basset and Grylls Mine, worked from 1852-1914 producing 4,650 tons of Tin. The site was then worked until 1938 under the name Porkellis Tin Mines. Much of the later workings were concentrated around “Old Mens Shaft” which was re-opened in 1907. The remains here are extensive with the concrete uprights of an elevated tramway surviving which took the ore from the shaft to the processing mill. The images on this page were taken on a perfect summers day in 1997. The area is well covered in Bob Acton’s Exploring Cornish Mines Volume 3.
The processing floors at Basset and Grylls Mine; in the foreground is a Buddle used to concentrate the Tin fines, in the background the remains of an Arsenic Stack.
A wider view showing the second Buddle, in the background were the foundations for a Rock Crusher.
The remains of a water tank in the vicinity of the Old Men’s Shaft, on the left of the image are mounting blocks for the shaft headframe and machinery.
A closer image of the water tank, standing high on three legs.
The remains of the large processing works at Basset and Grylls Mine.
A good view of the elevated tramway that brought the ore here for processing. The ground was full of drill steels poking above the surface.
The concrete pylons disappearing across Porkellis Moor.
A good image of the foundations for the Californian Stamps that were installed here.
More drill steels in the ground and another image of the machinery mounts.
A close image of one of the elevated tramway supports, partially hidden by the gorse.
These concrete frames were amazing to see, silent epitaphs to the industry that made Cornwall great.
This was a great subject to photograph on a good day with good clouds. So I made the most of it, looking down the line of supports, there were quite a few still standing.

Great textures and detail in the concrete plinths.
Basset and Grylls Mine has to be one of the most impressive sites I visited whilst taking pictures for Bob Acton, I tried to go back a couple of years ago, but I forgot the book and couldn’t find it again. Plenty of other summers to come. All the images were taken with an orange filter which darkens the blue sky and adds contrast.
