Clwyd Metal Mines Survey
Brynalyn
Brynalyn (also known as Great New Westminster or Pwllhelyg Mine) lies in the community of Llanarmon-yn-ial in the county of Denbighshire. It is located at Ordnance Survey national grid reference SJ19305880. The mine is recorded in the CPAT Historic Environment Record as number 18018 and this number should be quoted in all correspondence.Lead (Early 19th century-1885)
Geology
Carboniferous Limestone.
Workings
The Great New Westminster Mining Co took over the former Brynalyn sett in the 1880s. Evidence of workings remain as three large shafts, substantially capped, which lie on the lower slopes of the limestone crags to the east of Cae Harry (SJ19155890). The
capping has been broken away around the shaft at SJ19205885, to reveal it as a fine stone-lined shaft of some depth. A single shaft mound remains to the east of Pwllhelyg at SJ19555875, which may have been on the same vein or on a string from the
Blaen-y-nant Vein.
