An old copper mine located on the cliffs to the south and southwest of Hanover Cove. Wheal Prudence forms an amalgamation of the small and older Wheal Jacka, Wheal Cock and Wheal Meadow mines, although the precise locations of these old setts cannot now be determined.
The base of the 70-inch pumping engine house on the New Engine Shaft still survives, although the shaft itself is choked at the surface. The engine house survived in good condition until its destruction during the construction of the Second World War airfield at the site.
Other shafts can still be seen close to the cliff edge and on the coastal slope.
There are two principal lodes recorded being North (or Prudence) Lode and South (or New) Lode, there are also references to a Wheal Cock Lode and a Caunter Copper Lode.
Records indicate a production of some 7,000 tons of copper ore between 1821 and 1865, with 55 tons of tin produced in 1825-6 and a further 1 ton of tin in 1847-9.
Note on the mineral list: The reference to atacamite at Wheal Prudence is from Kingsbury. Given the doubts about the provenance of other Kingsbury specimens, this occurrence must be considered highly doubtful as well.
