Halkyn, Central/Halkyn, New North Mine
Primary Reference Number (PRN) : 103388 Trust : Clwyd Powys Community : Halkyn Unitary authority : Flintshire NGR : SJ20307070 Site Type (preferred type first) : POST MEDIEVAL LEAD MINE
Description : Lead (18th century-1913)
Geology Carboniferous Limestone with chert beds.
Workings The area was intensely mined from the 18th century and formed the site of large-scale operations in the 20th century by several companies. The Central Halkyn Mining Co (1901-1910) and the New North Halkyn Companies entered returns for the sett (Burt et al 1992).
Little evidence of workings remain in an area designated as a Welsh Development Agency Landscape Wales Project in conjunction with Delyn Borough Council.
Shaft mounds and spoil heaps remain surrounding the Pant Quarry area.
The Engine House of the New North Halkyn Shaft or Pen-y-bryn Shaft stood at SJ20307070 with the shaft to the west of it. This area now lies within the quarry. The shaft was the central area of the Halkyn District United Mines in the 20th century and became the main shaft on the Deep-Level Tunnel.
Transport The underground diesel railway of the Halkyn District United Mines served the sett (Richardson 1936).
Power The 20th century workings were powered by electricity.
The sett was drained by the Deep-Level Tunnel.
Processing Smith (1921) records the ores being dealt with at a concentration-plant near Lewis Shaft. The details refer to the early 20th century procedure: 'Ore is crushed with manganese steel jaws to fragments 8mm or less, this being the size of the largest jig-mesh. It is then sorted by trommels and water classifiers and passed into jigs. Elevator buckets used for re-crushing are also of manganese steel. At the new building the grades obtained from the jigs are mixed and recrushed, put through rollers and again through trommels and water classifiers....further separation of slimes is effected by round buddles.....'.
The sieved galena from the Pantygof vein, which contained no fluorspar was sent to the Potteries for glazing. The mixed grades were sent to Purex Ltd, of Greenford, Middlesex for smelting. Galena was sent to Parker & Co. of Bagillt and to Messrs Quirk, Barton and Burns of St Helens.
The buildings on this site were demolished in 1972.
A new mill was built around the Pen-y-bryn Shaft in 1932 (Richardson 1936) and these buildings were demolished in the 1960s.A large processing mill was erected the Pen-y-bryn Shaft in 1932 (Richardson 1936).
Other features The main workshops surrounded the Pen-y-bryn Shaft.
