Cwm Bach Mines and Trial Mines

Cwm Bach Mines are located in dense woodland of Cwm Coch, Cwmddauddwr.
Not in the Elan Valley but many of the mining trials are only a short distance from the bridleway leading up to Maen Serth Standing Stone.
Dates on the wall of the Mine Adit 1734 and 1736.

Cwm Bach Mine Adit

Cwm Bach Mine Adit, high up in the rocks of Cwm Coch Wood. Old lead mine dating back to 1734 according to the date engraved into the rock just inside the adit. The mine has 2 levels, the upper level is the level you go into at the entrance. Soon as you enter the adit you hit a flooded section of the level, this can be waist height. After reaching the dry part of the level there are two shafts dropping down to another lower level. One shaft call the Flooded Winze in the diagram below drops below the lower level and is flooded. The lower level is dug into the hill for another 30 metres, this lower level also continues back towards the adit entrance which joins up with the other shaft in the adit, called the Dry Winze. So far no written history as been found on the mine.
Difficult mine to get to. Bats hibernate in this mine during winter so please do not visit during winter.
Date on the right hand wall of the Adit, 1734 and 1736 maybe a name above the date

Cwm Bach Platform

On the left a short open cut possible adit which may have been covered by the forestry road. A small wall running for about 5m long and 1 foot high and a flat platform where they my have dressed and worked the ore. This seems to be built on a large spoil heap of very fine spoil. A larger spoil heap is above the forestry road which is behind the trees in the top left of the photo.

Area where there was another Mine Adit but I believe this may have been covered over when the forestry road was dug in just behind this area.
