Overview
Two small lead and silver mines south of Cubert, possibly the Treworthie mine worked by German experts in the 1550s and 1580s, recorded again from about 1785 and reworked to about 1864.
History
Trebisken and Trebellan were two small mines south of Cubert, Trebellan about half a kilometre east-south-east of Trebisken. They worked two north-south lead lodes crossed by an east-west lode; at Trebisken a single shaft was sunk on the intersection. Trebisken has been identified with the Treworthie mine described by the German Ulrich Frosse in 1584, which another German, Burchard Kranich, had also worked in the reign of Queen Mary, between 1553 and 1558.
The next recorded working was about 1785, and the collector Philip Rashleigh obtained a specimen of native silver from the mine. The mines were reworked several times up to about 1864, and in 1829-30 produced £4,000 worth of ore. Trebisken produced 861 tons of 65% lead ore and 9,190 ounces of silver, and under the name Trebisken Green Mine raised 7.5 tons of lead ore and 4 tons of black tin in 1861. The group was also known as Wheal Cubert and Cubert United.
