Bwlch Mine, the only Antimony Mine in Wales worked an east-west lode in dolerite from adits and at least one shaft said to be 120ft deep.

Little is known about the mine. It is shown as a "Mine of Antimony" on a map dated 1836 and 4 men were employed here in 1896.

The site has been largely flattened in recent years.
