Duchy Records state that in 1799 the Wheal Virgin mine was “raising tin fast,” and was owned by a company called Gill and Co, its agent was Captain Henry Banter. In 1836 a licence was granted to three men from Tavistock, Henry Prenton, Francis Prout, and John White to search for minerals on a tract of land known as Wheal Virgin. The licence was to run for twelve months at the cost of a 1/18 share or dues. (1)
