A prominent shaft collar is sited beside the farm track on the western part of the sett surrounded by overgrown dumps with few mineral samples. As of October 2018, it would appear that the large tip shown in the panoramic photo has been almost entirely removed leaving little of interest aside from the ubiquitous arsenopyrite and small amounts of galena.
