Cwm Elan Mine

Cwm Elan Mine, Elan Valley, Map Ref SN 901 651.

A vein of lead ore was discovered by a farm worker while digging a drainage leat for the land owner Thomas Grove of Cwm Elan House in 1796. Thomas Grove worked the mine making a profit of £500. Due to water problems Thomas Grove leased the mine to Sir Thomas Bonsall who added a Adit to drain the water.
A Cornish company took over the mine in 1808 following the death of Sir Thomas Bonsall.
Cwmellan Lead Mines worked the mine in 1840 and issued a Promissory Note for £1, one of these note can be seen in Llanidloes Museum.
Cwm Elan Mining Company was formed in 1871 with a capital of £30,000 and new machinery and buildings was erected.
A 10 fathom (60 foot) level was worked and in November 1872 Charles Ely was elected as Company Chairman.
In 1873 the Crushing Mill started with a Blake's Stone Crusher, Crusher Rolls, Collom's Patent Jiggers and Round Buddles which was all supplied by William Thomas of Llanidloes Railway Foundry.
The Cwm Elan Mining Company is voluntarily wound up in November 1874 and the property was offered for sale by public auction.
In 1875 the mine was bought for £1.148/10s/8d by the newly formed New Cwm Elan Mining Company.
Work ceased at the mine in September 1877, at this point the Engine Shaft had reached a depth of 40 fathoms (240 feet). The mine produced 175 tons of Lead and 160 tons of Zinc during the period of 1871 - 1877.

Crushing Mill and Water Wheel Pit

Crushing Mill and Wheel Pit. The crusher Mill would of held two large rollers, one driven by the water wheel and the other loose on it's shaft. Two large weight would of pulled the two rollers together to enable the ore to be crushed to the size of a course sand. The beams that once leaning against the south wall have been moved and laid just outside the Crusher mill. A few metal remains lay around this site including the large driveshaft that still retains half of a clutch mechanism for powering the mill.
