Wheal Coates is a former tin mine situated on the north coast of Cornwall on the cliff tops near Chapel Porth at NGR SW700501.  The area was worked for centuries but the workings under this name date from 1815 to 1912. The surviving buildings date from the 1870s when deep underground mining began at the site. There are three engine houses that formerly housed Cornish engines on the site, the most impressive being the 60” Pumping Engine House on Towanroath Shaft (restored in 1973). Above this engine house are the stamps and whim engine houses also both restored. The mine was not a great success with outputs of only 335 Tons of Copper and 717 Tons of Tin. That said these form an imposing relic well and are very photogenic.

In addition there are nearby 2 stacks and the various remains of the ore dressing buildings.
