The mine started work for copper during the 1720's. In 1787, the great copper slump forced the mine to close, but it was restarted in 1799. In 1836, the lower levels were abandoned since the copper ores became depleted. From 1844, it was re-worked for tin at greater depth, producing also small quantities of arsenic, cobalt, bismuth and tungsten. When it was closed in 1920, the mine had produced in total 80,000 tons of tin ore and 350,000 tons of copper ore.
