Lead (19th Century)

Limestone running into Cefn-y-Fedw Sandstone.

The Bog East Shaft was sunk at the eastern end of the Westminster Vein c1860. Stoddard's Silicon Quarries own the land and still pump the water for quarry use. The shaft, engine house foundations and chimney remain at SJ21305680.
The shaft to the north-west is capped , but now has a portal for Quarry use.

A second shaft is shown on the 1st edition OS map, but this remains only as a large spoil mound. To the south of the Bog East Engine House, a line of three shafts run north to south at SJ21305680.

Transport
No evidence.

Power
The chimney survives to approx 8m high and 2m diameter. Stone built and circular, it stands on a square plinth with a bricked flue arch and the flue apparently running out to the east.

The stone foundations of the engine house being south of the chimney, only survive to one course high, but give good indication of the plan of the engine house, boiler house, chimney and flue.

Processing
No evidence.

Other features
No evidence.
