An antimony mine on a NE-trending lode that crosses the small valley south of Port Quin. The workings included an adit driven from the west bank of the stream and two shafts near the top of the slope. The grid reference marks the approximate position of the adit portal, where a small dump is remaining. There is no trace left of the shafts above.

There are more dumps a little further south, towards Trevigo farm, both in the valley and in the corners of some fields along the slope where Hamilton Jenkin recorded two shafts, but it is unclear to which working they belong. Also note that the shafts and dumps that are located a little further west, near the cliff edge, do not belong to this mine but to the Gilson's Cove workings which were on a different lode.
