Approaching the site from the village of Ystumtuen the narrow lane climbs steeply and then turns sharply left defining the eastern and northern boundaries of the workings. In all the site is approximately 300m x 100m aligned east-west, divided into 2 roughly equal halves by a north-south farm track.
Within the bend of the road is an east-west aligned open working associated with small spoil heaps. In the middle of the site on the southern edge beside the farm track is a fenced shaft collar. The site generally has the appearance of many low mounds of spoil now grassed over.
At the time of this visit (Dec 2017) the site was being used as pony paddocks and no closer inspection was possible other than from the road.
It is however also possible that work took place to the north of the road. Though most of that is now tree covered there is a place occupied by farm machinery that has a prominent mound of what could be spoil.
