Located in Ordovician volcanics, shales, and slates, contains mineral deposits of galena, pyrite, and barytes, with the main lode running east-northeast to west-southwest. It features three visible levels and a shaft within an afforested area. The upper spoil tip is a prominent landscape feature, and the level remains open. Traces of tramway track beds and evidence of inclines between the levels are visible. Ore washing bins and picking tables are located near the upper level, and there are also poorly preserved building remains near the shaft, though their purpose is unclear.
