Wheal Maid Decline (incl. Whiteworks section), Wheal Maid (Wheal Maiden), St Day United Mines (Poldice Mines), Gwennap area, Camborne - Redruth - St Day District, Cornwall, England, UK

In 1983, Carnon Consolidated Tin Mines Ltd. started to explore the old Wheal Maid workings. An adit was driven, cutting three mineralized veins on a distance of 655 m. In 1984, this adit - declining to the southeast - was further driven ahead to connect this section to the Wheal Jane workings. In a depth of roughly 100 m, some levels of the old 'Whiteworks section' were cut, from where a number of interesting minerals was recovered.
