If you look in the field beyond GZ, the remains of a chimney of Wheal Vyvyan can be seen.
Wheal Vyvyan was worked mainly for copper and a little tin, The mine is situated on land owned by Sir Richard Vyvyan of Trelowarren, from whom it took its name. The main working here took place from 1827 until closure in 1864. About 80 men were employed underground and 30 men and boys at the two stamps; near Ponjeravah and at Polwheveral. A dozen ‘Bal Maidens’ were also employed breaking the copper ore, which was sent to Swansea for smelting.
