Worked for copper from the early 18th century, the mine changed to tin in 1865 and finally ceased work in 1913. In 1896, it was amalgamated with the Carn Brea mine to form the Carn Brea and Tincroft United mine.
The mine site is largely built over, but there are remains of the man engine and compressor house. These latter being part of the South Tincroft section of the mine.
