Another of the small copper mines around Richmond, it is in Billy Banks wood, where the Swale turns south and then sharply back to the east. Two levels were driven at Billy Banks, which does not appear to have been worked until 1905, when the Boulder Flint Company began work. That company was producing chert, from mines in Arkengarthdale, for the pottery industry. It seems likely, therefore, that the copper was found during a search for a new source of chert. Yorkshire Minerals Ltd worked the mine between 1910 and 1912 and then gave up.
Between them, the two companies produced 92 tons of copper ore, worth £3019, over seven years.
