Lead (Late 19th century)

Carboniferous Limestone.

The Mary Ann Shaft and the New Engine Shaft worked the Westminster Vein further east from the old Bog Issa Shaft. The Mary Ann Shaft at SJ20995686, was capped by the 1978 reclamation programme conducted by the NKC Partnership and remains under an area of scrap, reached up the track alongside the Bog farm gateway. The area around the shaft and engine house has been cleared of mining waste, which covers a substantial area on the 1st edition OS.

No evidence.

The substantial stone remains of the engine house walls survive to 2.5m in part to the north-east of the shaft. It apparently featured a stone bearing the date 1853. The features of the engine house are discernable but the chimney must have been cut by the later track to Waendyllog Farm.

No evidence.
