The Axton Vein runs east to west about half a mile south of Llanasa.

The old shafts on the western end of the vein lay to the southwest of Tyddyn-uchaf (SJ 1005 8040). The site remains as an area of grassed-over mounds. A large circular shaft, approximately 3 meters in diameter, with a dressed stone lining, is still visible at SJ 1096 8054, though it is roughly fenced off.

An earthwork bank runs east to west at SJ 1093 8053, likely the site of an earlier rectangular building. A further shaft mound lies to the west at SJ 1096 8057. Beyond Meadowcroft, old shafts continue along a line with areas of old quarrying. Noticeable shaft mounds can be located in the fields at SJ 1093 8049, SJ 1076 8048, SJ 1060 8041, and SJ 1050 8040. Additional shaft mounds are found near Ash Cottage (SJ 1043 8042).

The mine was abandoned by 1866 and appears as an Inactive Lead Works on the 1st edition OS Map of 1870. The OS map of 1899 shows the site as a single shaft with no related buildings.

The site of the mine is reached through old limestone gateposts leading off the road from Llanasa to Four Crosses, opposite a house now called Meadowcroft.
