Disclaimer: the engine house is definitely in the photos. Behind all the green stuff. Honestly.
Wendron Consols opened as an underground mine in 1851/2, although records show it was working for at least 90 years previously (and possibly as early as 1493 as tin streaming works). It was a moderately successful mine that worked six lodes, producing both copper and tin. From 1854, its neighbour Wheal Roots and the Trenear stamps were put under the same management and the majority of its ore was sent to this site for processing. Wendron Consols closed for good in 1869.
In 1855, a 60-inch pumping engine was built and pumped out of four different shafts, using flat rods to achieve this. At this time, 24 heads of stamps were being run by waterwheels, with another 8 heads being added shortly after.
In 1860, a pumping engine was erected on Baldee’s lode. This would have been to the east of Engine shaft, although nothing of this remains today. The number of stamps was increased to 51 heads, with a further 4 being added the following year.
In 1867, a 70-inch pumping engine with 2 boilers, a 50-inch pumping engine and 18-inch whim with 1 boiler were advertised for sale. The same 70-inch and 18-inch engines were for sale again each year after.
In terms of winding engine houses, all my resources have contradicted each other so here’s a list: Spargo: 1864 24-inch winding engine house, Acton and Brown: 18-inch whim, advertised for sale in 1866, Hamilton Jenkin: 22-inch whim erected in 1860
Lodes included Richard’s, Flander’s, Liddlecote, Hurrler’s/Main, Grace and Grenfell. Output for the mine between 1854-1869 was 2,390 tons of tin and 48 tons of 16% copper.
The mine had a number of shafts: Engine (55-fathom/100m), Hill’s (80-fathoms/146m), Richard’s (20-fathoms/37), Barclay’s (12-fathoms/22m), Bishop’s (12-fathoms/22m), Hurler’s (32-fathoms/59), Robert’s (22-fathoms/40m), Sleeman’s (35-fathoms/64m) and an unnamed shaft (35-fathoms/64m).
All that remains of Wendron Consols is the wall of the main pumping engine and the puddle that is the top of its shaft. Said engine house currently lives in an overgrown hedge along a public footpath in Trenear.
I can’t find any mention that this shaft is officially capped, nor any of the other shafts that are situated off the footpath in the jungle. The land around the footpath is all private property, seriously overgrown and dangerous to venture into.
