Mine	Region	Worked	Commodities
Nab Gill Mine The small, disappointing iron mine that the Ravenglass and Eskdale Railway was built to serve; the railway outlived it by more than a century.	Cumbria	By 1842–July 1918	Iron
Nabb Colliery The one Rossendale pit its owners thought worth pithead baths, closed by the Coal Board only seven years after nationalisation.	Lancashire	By 1894–March 1954	Coal
Nailstone Colliery It never pumped: the water that ran into its shafts was let collect in the sumps and hauled out overnight in self-filling tanks on the cages — and long after it stopped winding coal, three other collieries brought theirs up here.	Leicestershire	1862–1967	Coal, Fireclay
Nangiles Mine Substantial 19th-century copper mine near Chacewater, reaching 70 fathoms by 1819 and reworked from 1862 with an 80-inch pumping engine on Engine Shaft — and the point of discharge for the 1992 Wheal Jane acid mine water pollution incident.	Cornwall	by 1808–1915	Copper, Tin, Zinc, Pyrite
Nant Fach Colliery One of the last horse-worked mines in South Wales, whose two ponies retired to an RSPCA home when it closed in 1998.	Neath Port Talbot	1991–20 March 1998	Coal
Nant Gwrtheyrn Quarries Too steep for a road, so the setts went out by sea from three jetties — and the quarrymen's village, wrecked by squatters, was bought back for £25,000 and is now a Welsh language centre.	Gwynedd	1851–1939	Granite
Nant Hir Colliery Worked largely single-handed by Albert Thomas for over a decade, using a horse for haulage; novelist Iris Gower went underground here in 1988 while researching her novel Black Gold.	Neath Port Talbot	1979–November 2024	Coal
Nant-y-Garw Lead Mine Most Welsh lead mines grew messily over a century or more, one owner's additions piled on the last — Nant-y-Garw did all its growing and dying inside a single generation, which is exactly why what's left today reads as one coherent design rather than an accumulation of afterthoughts.	Powys	1877 (vein discovered)–1899	Lead
Nantewlaeth Colliery A deep upper Afan valley pit with its own miners' halt, closed within two years of nationalisation.	Neath Port Talbot	1915–November 1948	Coal
Nantgarw Colliery The deepest pit yet sunk in the South Wales Coalfield on its 1911 completion, so troubled by geology and labour disputes that it closed within 16 years and sat idle for a decade before becoming the National Coal Board's first major post-nationalisation redevelopment scheme.	Rhondda Cynon Taf	1910 (sinking from 1911)–6 November 1986	Coal
Nantiago Mine A lead and zinc working on the eastern flank of Plynlimon, powered by water diverted from the Nant Iago via a network of leats.	Powys	before 1846–c.1918	Lead, Zinc
Nantmelyn Colliery A colliery that started under one name, failed, and was reopened under a completely different one went on to employ more men under its second identity than most collieries ever manage under their first.	Rhondda Cynon Taf	1856–1957	Coal
Nantwen Colliery Sunk from 1878 to 1883 for the Dowlais Iron Company (later GKN); decades of detailed manpower and output figures survive, peaking at 540 men and 158,360 tons of coal in 1918.	Merthyr Tydfil	1878–83 (sinking)–1924	Coal
Nantyffin Colliery Grew from 23 men in 1927 to nearly 500 by the mid-1940s under Dowlais Collieries Ltd, later merging into Bedlinog Colliery.	Merthyr Tydfil	By 1927, possibly earlier–1980s	Coal
Nantymwyn Mine Once the largest lead mine in south Wales, reputedly earning its 18th-century owner £300,000	Carmarthenshire	1747–1932	Lead, Zinc
National Colliery Thirty-three of the dead were under fifteen years old — the 1905 explosion killed a generation of Wattstown boys alongside their fathers.	Rhondda Cynon Taf	From around 1880–1968	Coal
Naval Colliery The same pit killed 101 men in 1880 and another 12 in 1884 — and kept working for another 74 years after that.	Rhondda Cynon Taf	1875-79 (sinking)–1958	Coal
Navigation Colliery Rated by the Royal Commission on the Ancient and Historical Monuments of Wales as the best-preserved colliery complex in South Wales, with thirteen listed buildings surviving intact.	Caerphilly	1907 (sinking)–1967	Coal
Navigation Colliery, Talywain Its engine house keeps the base of a Waddle fan, a rare survival of the large open fans once common at South Wales pits.	Torfaen	By 1878–1939	Coal
Nebo Level A Cory Brothers house-coal level that ran a mile and a half into the mountain and outlived its parent pit's house-coal shaft.	Rhondda Cynon Taf	to July 1953	Coal
Neilsland Colliery A Hamilton colliery that grew to nearly a thousand men within fifteen years of sinking, and lost five when washery sludge from an old shaft burst into its workings in 1916.	South Lanarkshire	1894 (sinking)–c. 1932	Coal
Nelson Colliery A short-lived Cramlington pit of 1934-58 that employed nearly 500 at its peak.	Northumberland	1934–4 January 1958	Coal

Nenthead Mines Core of the North Pennines orefield; one of England's highest villages	Cumbria	1737–1961	Lead, Silver, Zinc

Nentsbury Mine The largest workforce in the 1930 Cumberland return — 108 men underground for a Belgian zinc company.	Cumbria	to 108	Lead, Zinc

Nether Loads Farm Red Lead Mill It holds the only known red lead mill building left standing above ground anywhere in England.	Derbyshire	1581–by mid-19th century	Lead
Nether Ratchwood and Rantor Lead Mines Discovery of the rich ground beneath the two mines was delayed for years by a dispute over payments to the very sough company whose drainage work eventually made working them possible.	Derbyshire	1740s–1860s	Lead
Nethercroy Colliery A Carron Company pit on Croy Hill that revived pre-1859 ironstone workings and ended by raising only coking coal.	North Lanarkshire	c.1890–1914	Coal, Ironstone

Netherton Colliery Four pits sunk over a century, a waggonway of its own to Blyth, and a village that grew up around it.	Northumberland	By 1828–5 January 1974	Coal
Nettlesworth Colliery A Victorian pit that became a pumping station, then lent its name to a drift that worked into the 1970s.	County Durham	1861–27 September 1974	Coal
Nettleton Top Mine Possibly the first ironstone mine in the country to run diesel locomotives underground — and it still had horses at the face on its last day.	Lincolnshire	1934–1968	Ironstone
Neumann's Mine Northwich has spent more money making Neumann's Mine safe long after it closed than the mine itself was probably ever worth -- 780,500 cubic metres of infill, at depths of 90 metres, to undo what one collapsed roof did in a single event over a century earlier.	Cheshire	19th century–19th century	Salt
New Boston Colliery Richard Evans' Ram Pit at Haydock, sunk about 1854, where a Sunday repair job on a falling brow in 1905 buried the under-manager, his brother and three datallers.	Merseyside	c. 1854 (museum: 1880)–1907	Coal

New Chiverton Consols A small satellite of West Chiverton, named to catch investors, whose 1868 engine house still stands by the old railway.	Cornwall	1863–1877	Lead, Silver, Zinc
New Consols Mine Few mines changed their name as often as this one — Wheal Martha, Great Wheal Martha, New Wheal Martha, New Great Consols and finally New Consols — a small clue to just how many times the site was reorganised, refinanced and rebranded across more than a century of working.	Cornwall	From the 19th century–1953	Tin, Copper, Arsenic, Lead, Silver
New Copley Colliery A Cockfield coking-coal pit of over 200 men whose 1872 shaft accident killed three men lowered with the engine out of gear.	County Durham	from 1867	Coal

New Glencrieff Mine New Glencrieff has the distinction of being both one of the richest lead mines Britain ever had — an estimated 105,000 tonnes of lead smelted from its ore over two and a half centuries — and the very last mine standing in a village, Wanlockhead, that had lived and died by lead mining since the 17th century.
