Mine	Region	Worked	Commodities

Pallaflat Iron Mine A Bigrigg haematite pit of 1874 to 1914 whose spoil heaps gave the mineral world its butterfly-twinned calcite and green baryte a lifetime after the ore ran out.	Cumbria	1874–1914	Iron
Palmerston Quarry It undercut the quarry above it, and brought down 6.25 million tons of rock on itself.	Gwynedd	1825 (Welsh Slate Company lease)–1883	Slate
Pandora Mine A Gwydir Forest lead-zinc mine whose ore fed the purpose-built Klondyke processing mill via a two-mile tramway along Llyn Geirionydd — later the stage for one of Welsh mining's most brazen 1920s investment frauds.	Conwy	From around 1868–1931	Lead, Zinc

Pantdreiniog Quarry Reopened in 1901 as a workers' cooperative by William John Parry, the 'Quarryman's Champion', specifically to employ men locked out of the neighbouring Penrhyn quarry during Britain's longest-ever industrial dispute -- and later renamed two of its own steam locomotives after the union's own leading figures.	Gwynedd	From around 1825–1930	Slate
Panteg Colliery A Pontypool coal level of the Panteg steelworks' owners that grew to 350 men within two years, closed in 1926, and was revived under another company's name.	Torfaen	1915–1926	Coal

Park Mines Henry Schneider's last-chance trial pit, costing about £50, found the Park haematite deposit in 1850, and that find led to Barrow's blast furnaces.	Cumbria	1850–1921	Iron

Parkend Colliery The Parkend pits of Edward Protheroe, Dean's biggest producer in 1856 and New Fancy's lifeline until 1944.	Forest of Dean	By 1827–1944	Coal

Parkfield Colliery Its Brandy Bottom engine house survives as a scheduled ancient monument, one of the most complete relics of the Bristol coalfield.	Bristol	1851 (sinking)–15 August 1936	Coal

Peak Alum Works Peak's alum works burned through roughly 100 tons of shale, and up to 200 tons of imported human urine, every year — to make barely a fraction of that weight in alum, England's first great chemical industry running on little more than fire, patience and other people's waste.	North Yorkshire	1640 (discovery)–1862	Alum
Peakshill or Oden Sough Driven at real productive expense between 1726 and 1729 to both drain Odin Mine and hunt for new ore, the sough never found what it was looking for -- the vein dips away beneath Rushup Edge just beyond its end.	Derbyshire	from 1726–1729	Lead

Pen-ffordd-goch Ironstone Scours Iron ore won by turning water loose on a hillside — and datable to the year, because the scouring stopped when the reservoir that would have supplied it was built in 1817.	Blaenau Gwent	At least the 17th century–by 1817 (scouring)	Ironstone, Coal
Pen-y-Bryn Mine Became, for a period in the 20th century, the centre of the large-scale Halkyn District United Mines operation, itself an amalgamation of nine former mining companies.	Flintshire	By 1899–1957 (ore winding ended)	Lead, Zinc
Pen-y-Bryn Quarry The quarry's own name comes from a 17th-century house that continued to be lived in even while the quarry worked around it, remaining occupied until after the Second World War -- and the complex of surviving buildings, including its workers' cottages, a saw mill and a weighbridge, is unusually complete for a Nantlle Valley quarry.	Gwynedd	By 1808–1950	Slate
Pen-y-fan Colliery Levels on Mynydd Pen-y-fan that passed through seven sets of hands, from a baronet's lease of about 1803 to a small-mine owner of the 1890s.	Blaenau Gwent	c. 1803–after 1923	Coal

Pendarves Mine Simms Shaft, sunk in 1967-68, was the first entirely new shaft sunk anywhere in Cornwall in forty years -- a rare vote of confidence in tin mining that the 1985 tin crash ended within two decades.	Cornwall	1967 (Simms Shaft sunk 1967-68)–1985	Tin
Pendeen Consols Its old workings now lie directly beneath Pendeen Lighthouse.	Cornwall	1856–1870	Tin, Copper
