Great Condurrow Mine in the back and beyond on Troon has been around for a while, although in varying forms.

Great Condurrow

A Higher Condurrow mine was working as far back as 1815, but closed in 1830. It reopened again at some point, producing fairly good amounts of copper and then tin before closing again in 1873.

The sett was reworked again from 1880-81 (although output record dates differ) under the name Pendarves United, following its amalgamation with Tryphena Mine, Wheal Nelson, West Condurrow and Tolcarne. It was reworked for the final time between 1906-14 as Condurrow United. The final reworking was fairly unsuccessful as they struggled to make Woolf’s shaft safe to use, with costs mounting.

Woolf’s (or Neame’s) pumping engine house was built in 1906 during the final reworking. This housed a 80-inch engine built by Harvey’s & Co, having originally come first from West Chiverton where it worked from 1869-1882; the engine then went to Garland shaft at Gwennap United from 1899-1905, before finally making its way to Troon. The engine house was originally going to be built on the north side of the shaft, but the ground proved too unstable. It’s boiler house used to stand on the east side and housed four Cornish boilers.
Remains of a horizontal whim and air compressor lie on private land to the east.

Woolf’s (283 fathoms/518m), Pryce’s/Sump/Engine (330 fathoms/603m), Hope’s (290 fathoms/530m), Llandower (130 fathoms/238m), Smith’s (110 fathoms/201m) and Adit (12 fathoms/22m). 

Main, Llandower, Robert’s and South. 

30,495 tons of 6.75% copper, 2,030 tons of black tin, 6.5 tons of pyrite and 35 tons of arsenic.

2,660 tons of black tin, 575 tons of 6% copper and 56 tons of arsenic.

As well as Woolf’s 80″ pumping engine there were several others on the mine. Pryce’s had a 36″ pumping engine by 1850 and a 21″ whim in 1863. There was an 18″ whim on Hope’s shaft which later worked a crusher as well.

Woolf’s pumping engine house is right on the side of the road and free to access, the site has been consolidated and made safe. The Carn Brea Mining Society own the Pryce’s/Llandower part of the mine and are busy putting it all back together; this section can be seen from the footpath running along it, but the land is private. Other bits and pieces are also on private land.

The closest parking is at King Edward Mine.
