One of many lithium prospects along the flank of the Leinster granite. Most of the Li occurs as spodumene (white laths up to 30 cm long) but this locality is unique in that a pink lithium-rich muscovite also occurs. As with all the Leinster Li localities, there are no outcrops, just boulders along the edges of fields.
