2020-8-3  By 1870, the mine had reached 160 fathoms (m) in depth and was working mostly for pyrite and blende. The main issue was that the water in the mine was incredibly corrosive and the pumps had to be lined with brass, a very expensive outgoing for the company. Between 1905 and 1915 the mine was worked as part of Falmouth Consolidated Mines.
