Ref.: Dana 7:II:280. A lead mine.
Irish grid ref. L 993517.
The site has 3 sets of spoil heaps, they are found up along the hill.
Various adits are above the highest spoil heap but they are barren mineralogically wise.
In the schist waste are pockets completely infilled with calcite and gypsum. One can etch the infilling material with HCl to show pyrite crystals up to 1cm and small galena crytals.
