Pool Park Boundary Shaft

Pool Park Boundary Shaft lies in the community of Minera in the county of Wrexham. It is located at Ordnance Survey national grid reference SJ25155050. The mine is recorded in the CPAT Historic Environment Record as number 18144 and this number should be quoted in all correspondence.

Lead/Silver/Zinc (1860-1881)

Geology
Carboniferous Limestone outcropping from Cefn-y-fedw Sandstone.

Workings
The Pool Park Vein and the South Minera Vein intercept below the most westerly workings and processing areas of the Park Setts. Boundary Shaft lies to the south-east of the main site at SJ25155005.

Transport
A tramway runs from the Pool Park Main site past a shaft at SJ055006 and continues to Boundary Shaft at SJ25155050. A track connects Boundary with an old shaft at SJ25255045, which is capped with concrete.

Power
A very substantial leat system appears as an earthen bank running around the perimeter of the sett above the Aber Sychnant Valley. An immense amount of water was necessary for the washing and separation of lead.

Processing
The stone foundations of an ore bin underlie the turf at Boundary Shaft. The ore bin drops to the raised track to connect these workings with the main site and the dressing floor areas that lie to the west of the main whim shaft (SJ24955007).

Other features
The stone foundations of possibly a shed lie to the east of Boundary Shaft.
