Mining
In 1788, Wheal Mary mined an east–west lode (near Drift) which was in both Paul and Sancreed parishes. It later became known as Garth (or Gath) mine. Following a period of idleness operations resumed under the name of East Wheal Cock and work continued to 1843 when the mine was known as Wheal Darby. Over forty years after the mine closed, a capped shaft at Bologas was reported to have collapsed and the mine was referred to as ″Gath mine″ in The Cornishman newspaper. All signs of the mine on the ground had disappeared by 1925, although quantities of ″wood tin″, continued to find their way into Cornish mineral collections.[17][18]
