John's Mines

As his career progressed and wealth increased, John began to invest in mines. One of which was Wheal Caul or Wheal Castle at the end of the Tregeseal Valley. It was fitted with the largest water wheel in the County - some 50 feet in diameter. The shares were offered for sale in the Mining Journal after John’s death.

The mine was one of those that pursued mineral lodes under the sea. Drainage was important and difficult in mines of this type but with the knowledge and expertise he showed in Mexico it is not surprising he would be interested in this mine. Many of the abandoned buildings were washed away in a violent storm in 1902 when a torrent of water tore down through Tregeseal Valley to the sea. Amongst the present day ruins the huge housing for the giant water wheel can still be seen.
