Wheal Grambler mine

Wheal Grambler mine, formerly known as East Wheal Sparnon, was worked between 1792 and 1798 and again between 1805 and 1808. Wheal Grambler was amalgamated with St. Aubyn mine in 1834, which included North Wheal Grambler mine. Finally, known as St. Aubyn United, it had raised over 12,500 tons of copper ore, and closed in 1893.

The area to the south on the opposite side of the track to the cache location was the store yard for materials used in the mine and also for the ore recovered. Little remains of the engine house and the site is inaccessible, go along the track to the east, the engine house was to the north just before the track turns north.
