The Western Shaft stands to the west of the road leading up to Esclusham Mountain from Minera. It is now substantially capped at SJ 2540 5140, with the remains of its adjacent engine house. The site is in a poor state of preservation, with little structural integrity remaining. Several smaller shafts surround the main shaft, indicating the extent of mining activity in the area. The incline that once connected Hill Shaft with the dressing floors at Western Shaft is still traceable, though overgrown and degraded.

The engine house, which once housed the power systems for the mine, has been almost entirely destroyed, leaving behind only the basal engine mountings. The sett is intersected by the Gwter Siani Leat, which follows the contours of Esclusham Mountain. This water channel carried water downhill from the moorland above Wynnstay sett to the Minera Mines in the valley.

Processing waste remains scattered across the site, with extensive spoil heaps and dressing floor debris still visible. In more recent years, modern building waste has been dumped in the area, further altering the landscape.

The Western Shaft of Park Mine was sunk before 1850 and remained in operation until the late 19th century. The Park Mines were drained by an extension of the Minera Upper Day Level from Speedwells Shaft. In 1877, the Minera Mountain Company took over the later workings of South Minera and Park, continuing operations until 1913
