St Just United Mines
A number of small ancient tin mines operated on Ballowall and Bosorne Common. During the 19th Century these were amalgamated, eventually into St Just United Mines which operated until the 1880s.
Some exploration took place near Porth Nanven from the 1890s into the early 20th Century (hence the concrete remains). This was to investigate mining the lodes from the St Just United mines at greater depth and beneath the sea, but the site was abandoned after World War II.
