About half a mile to the southeast of Wheal Prosper lie the remains of Wheal Trewavas. It was opened in the mid 1830's. There are records showing that at one stage in the early 1840's the concern employed around 200 people. In the mid 1840’s a new shaft was sunk on the eastern section of the sett. This new shaft known as Diagonal shaft reached a depth of nearly 600 feet. Quite why the mine closed within the next couple of years is unknown but there seems to have been some question of financial irregularities or some foreclosure by the banks. In any event, the mine was allowed to flood and the majority of the saleable assets sold off. In the decade that Wheal Trewavas was in operation it produced over £100,000 worth of copper ore.


This photograph shows how precariously balanced this mine is. This image was taken on a bright sunny day creating sharp clean angles and rich dark shadows. The addition of the s-like wall to the right of the mine and the diagonal line of the cliff face has added some fascinating elements to this composition.
