Worked from 1810 to 1863, producing 11,000 tons of copper and some quantities of tin. Extensive dumps are still located in the area bordering Kestal Farm.

This collecting location is ideal for those who are limited in mobility. One can park on the grass verge opposite the entrance to the site and simply cross the lane to gain access. The site is pretty level with a minimum of overgrowth to hamper progress. Several spoil heaps to choose from with much material scattered about the site. As always, permission must be sought & granted to enter private land. Information as of August 2015 J. I. G. R.
