“In every out-thrust headland, in every curving beach, in every grain of sand there is the story of the earth”
Transient ‘golden hour’ winter light bathing the cliffs around Towanroath engine house, between Chapel Porth and St. Agnes in Cornwall, UK.
The Wheal Coates mine opened in 1802 and was worked until its closure in 1889. It was re-opened for a short period between 1911 and 1913 when it was finally closed.
The site is most notable for its three engine houses and in particular the iconic Towanroath Shaft engine house, which is now a Grade II listed building. The whole site is in the care of the National Trust.
Built in 1872 the Towanroath engine house was responsible for keeping the water out of the shaft 600 feet deep shaft of this tin mine.
The other two engine houses on the site were stamping and winding (whim) engine houses, built at around the same time. These were responsible for hoisting and crushing the tin ore.
There is also evidence of prehistoric and medieval mine workings in the vicinity including signs of excavations in the Towanroath Vugga cave on the beach below
In its heyday Wheal Coates employed some 140 miners with tin being transported on the tramways and shipped from Portreath, Hayle, Trevaunance Pier in St Agnes and Truro.
Cassiterite has been the chief tin ore throughout ancient history and remains the most important source of tin today. It is a widespread minor constituent of igneous rocks. The old exhausted workings of Cornwall, England, are concentrated in high temperature quartz veins and pegmatites associated with granitic intrusives. The veins commonly contain tourmaline, topaz, fluorite, apatite, wolframite, molybdenite, and arsenopyrite.
