Located in Ordovician volcanics, shales, and slates, with mineralization of galena, pyrite, and barytes. The main lode runs east-northeast to west-southwest. The workings at the site include three levels and a shaft, located in forested area.
Upper spoil tip forms a significant feature within the landscape, and the upper level remains open. Traces of tramway track beds are visible, and evidence of inclines between levels is present. Ore washing bins and picking tables can still be seen by the upper level. There are also some poorly preserved building remnants near the shaft, though their specific function is unclear.
