Trenethick Wood Mine was described in 1724 as 'an old mine considerably developed, anciently worked for tin which is still found in the upper levels. Worked at present for copper which sells for £15 per ton, 40 tons of ore recovered in 6 months and transported to Warrington via Hayle for smelting'.
It was here in 1799 that Richard Trevithick installed a plunger pole pump worked by water pressure.
