The mines in the St Ives Mining District have suffered over the years, there are now very few obvious remains left. Large scale mining here generally declined during the latter part of the nineteen century, due to the low Tin prices. By 1890 all the mines had closed. In 1905 there was a slight resurgence when the price of Tin again rose, St Ives Consols and Giew Mines were the last to work, Giew was the final mine to close in 1922. The mines in this area were well known for huge underground ore bodies known as Carbonas, these were principally found in St Ives Consols and Rosewall Hill Mine, after they were mined out they remained as huge empty caverns, now silent and filled with dark water.
The Pumping Engine House of Giew Mine from the boiler house side. The shaft here is 225m deep and known as Frank’s Shaft. It is situated on the Western side of Trink Hill beside the B3311. The mine worked from 1838-1922 producing 145 tons of Tin. The engine house was conserved in 1994.
One of my favorite places in the St Ives Mining District.This image was taken standing on top of Rosewall Hill looking towards the sea. The second chimney in the background belonged to St Ives Wheal Allen, regrettably this collapsed in 2014/2015.
The two chimneys belong to Rosewall and Ransom United Mine, this worked from 1839-1876 producing 1,500 tons of Tin. The closer stack served the whim and the lower belonged to the pumping engine, the engine houses still survive but are covered in ivy and deep in the gorse.
The twin stacks from a slightly different angle, the town of St Ives is in the distance.
Looking up Rosewall Hill from the bottom. The two engine houses can still be seen in the undergrowth, the stacks are further up the hill. Now (2017) the engine houses are totally covered in vegetation.
Near the summit of Watchcroft is the remains of the Bob wall of Garden Mine, the walled shaft can be seen infront of the engine house.
At 700ft above sea level it is the highest mine in Cornwall.
The engine house is very exposed to the weather and it has suffered over the years. he mine worked from 1838-1870 producing only a few tons of Tin.
Located in Zennor near St Ives, Rosevale Mine is owned by the “Rosevale Historical Mining Society” who are a group of underground enthusiasts and ex-miners. They are dedicated to the restoration of the underground workings using traditional mining methods. Click the image to navigate to the page on this interesting mine.
The scant remains of Gurnard’s Head Mine. This was a small Copper Mine which started before 1821. The workings here are said to go out under the sea.
The engine house is in a poor state of repair. The mine worked from 1821-1847 it produced only 25 tons of Copper.
The two surviving engine houses of Carn Galver Mine built in 1871. The mine closed in 1876 having produced 150 tons of Tin.
