Mine	Region	Worked	Commodities
Sutton Manor Colliery Its spoil tip now carries Dream, a 20-metre sculpture of a girl's head commissioned by former miners	Merseyside	1906–1991	Coal
Sygun Copper Mine Reopened in 1986 as an underground show mine in the heart of Snowdonia	Gwynedd	18th century–1903	Copper
Taff Merthyr Colliery One of the last deep mines sunk in South Wales under private ownership, it became a flashpoint of 1930s industrial unrest when riot police were brought in.	Merthyr Tydfil	Shafts sunk 1922-24; production from 1926–1992 (Taff Merthyr); Trelewis Drift closed 1989	Coal
Talargoch Mine At its height Talargoch's pumping plant ran to an 80-inch engine, a 100-inch Cornish engine and thirteen smaller engines simultaneously — a small industrial army assembled for one job: keeping 200 feet of waterlogged glacial gravel from drowning the mine beneath it.	Flintshire	documented from 1303; worked continuously from the 1630s–1884 (underground); tip-reworking to 1905	Lead, Zinc
Talnotry Mine Nickel mines are vanishingly rare in Britain, and Talnotry's spoil heaps are valued today less for what could still be dug out of them than for the mineral specimens already sitting on the surface — nickeline and gersdorffite unlike almost anything else in this archive.	Dumfries and Galloway	discovered c. 1885–abandoned soon after opening (exact date unrecorded)	Nickel, Copper
Tankerville Mine Tankerville's 1,690-foot shaft — the deepest anywhere in the Shropshire orefield — makes an odd kind of monument: a huge investment in depth chasing the richest vein the county ever recorded, defeated in the end not by running out of lead but by the price of lead itself collapsing under it.	Shropshire	small-scale working from the early 19th century; major development from 1864–May 1884 (main); failed reopenings 1891-93, 1911-13	Lead, Silver, Zinc, Barite
Tarbrax Oil Shale Mine A remote outlying works of the Scottish shale oil industry, its huge red waste bing still visible for miles	South Lanarkshire	1870–1930s	Oil Shale
Thoresby Colliery The Miners' Institute (1939) and pithead baths (1949) served a close-knit community whose canteen was named Coal Board 'Canteen of the Year' in 1979, beating fifteen other NCB areas.	Nottinghamshire	Sinking 1925-28; coal reached 25 April 1928–10 July 2015	Coal
Threlkeld Quarry and Mine A granite quarry with a reconstructed underground lead and copper mine, now a mining museum	Cumbria	1870–1982	Granite, Lead, Zinc
Tilberthwaite Tilberthwaite's working life spans an almost absurd stretch of British mining history in one place — Elizabethan lead and copper prospectors in the 1500s, Victorian mining ambition driving a thousand-yard adit, and a slate quarry that was still being worked into the 21st century.	Cumbria	worked from the late 16th/early 17th century (Elizabethan); slate quarrying from the 18th century–copper mining ceased 1942; slate quarrying continued intermittently to 2001	Copper, Lead, Slate
Tilly Whim Caves 'Tilly Whim' most likely commemorates a quarryman named George Tilly and the wooden crane, the whim, that swung his finished stone down to waiting boats — the very same kind of crane that gave its name to the winding whims used at metal mines across Britain.	Dorset	Worked predominantly through the 18th century; possibly earlier–Quarrying ended around 1812; closed to public access in 1976	Freestone
Tilmanstone Colliery Its coal reached Dover harbour by a three-mile aerial cableway through tunnels cut into the White Cliffs — built for exports that never really came	Kent	Sinking began 1906; coal reached 1912–1987	Coal
Tincroft Mine Carn Brea and Tincroft together raised nearly half a million tons of copper in their combined working lives — output on a scale that puts them among the genuine giants of the Camborne-Redruth district, even though most of the mine's surface footprint today has simply been built over.	Cornwall	known by 1680s (as Penhallick Vean & Tyn Croft); tin production from 1865–1921 (South Tincroft)	Copper, Tin
Ting Tang Mine Carharrack mine in the West Clifford United sett, worked for tin before 1810 and copper through the mid-19th century.	Cornwall	worked by 1816 for copper; some sources attribute earlier tin working, unconfirmed this pass–by 1870, as part of the Clifford Amalgamated Mines combine	Copper
Tomnadashan Copper Mine A short-lived Loch Tay copper venture later used as a filming location for Monty Python and the Holy Grail	Perth and Kinross	1841–1862	Copper, Gold
Totternhoe Stone Mines Totternhoe's stone built Westminster Abbey and Windsor Castle from galleries dug directly beneath its own medieval castle — mining and fortress standing one on top of the other for 600 years.	Bedfordshire	Worked from the Roman period; underground galleries from the medieval period–Underground working ended around 1925; small-scale surface extraction continues	Chalk
Tower Colliery Tower's 1994 closure and worker buyout became a genuine national story — a mine British Coal had declared unviable was run profitably by its own former workforce for another thirteen years, closing only once the coal itself, not the economics, ran out.	Rhondda Cynon Taf	coal worked from c. 1805; Tower drift sunk 1864–1994 (British Coal); reopened 1995; closed for good 2008	Coal
Tranent Collieries Scotland's first railway was built here in 1722 for one purpose only — getting Tranent's coal two and a half miles downhill to the sea	East Lothian	Monastic working from the 13th century; industrial-scale mining from the 18th century–1963	Coal
Treak Cliff Cavern One of only two places on Earth where Blue John fluorspar is found, mined since the 18th century and now a show cave in the Peak District.	Derbyshire	c.1745-50, as Millers Mine–Commercial bulk mining ended 1926; opened as a show cave 1 April 1935, with small-scale jewellery-grade extraction continuing	Fluorspar, Lead
Tregargus China Stone Quarries China clay gets all the fame, but china stone is the ingredient that actually holds porcelain together — ground here by a waterwheel thirty feet across	Cornwall	Worked from around 1870–1965 (last mill closed)	China Stone
Trelogan Mine A North Wales lead, silver and zinc mine that housed Flintshire's first Newcomen engine in 1732 and worked on until 1911 under the chemical firm Brunner Mond.	Flintshire	Worked from c.1694 by the Governor and Company for Smelting down Lead with Sea Coal–1911 (final closure under Brunner Mond, which had reopened the mine in 1897)	Lead, Silver, Zinc
Tresavean Mine Before Michael Loam's man engine, reaching a working level at Tresavean meant climbing down — and, at the end of a shift, back up — as much as 1,728 feet of fixed ladders underground; the same journey on the new machine took a fraction of the effort, just by stepping from platform to platform as the rods rose and fell.	Cornwall	1737–1928	Copper, Tin, Arsenic
Treskerby Mine A productive Gwennap-area copper mine, part of the wider Consolidated/United Mines district.	Cornwall	already active by 1800–abandoned a few years after 1828; briefly reopened 1860 and 1922-27	Copper, Tin, Fluorspar
Tylorstown Colliery Named for the village that grew up around it rather than for its owners, Tylorstown was, administratively, simply another set of Ferndale's own numbered pits by the time disaster struck it in 1896.	Rhondda Cynon Taf	No.6 & 7 (Pendyrys) sunk 1873-76; No.8 (Cynllwyn Du) originally sunk 1858, deepened 1892–Nos. 6, 7 and 8 closed 1936; No.9 closed 1960	Coal
Tyndrum Mines Tyndrum owes its lead mine to an accident of estate boundaries: Sir Robert Clifton, prospecting the Breadalbane estate he had leased in 1730, stumbled on the veins in 1741 without setting out to find them, and the mine his discovery started outlived him by nearly two centuries.	Stirling	1741 (vein discovered)–1926	Lead, Silver, Zinc
Ullcoats Mine Once called 'the most prosperous and productive iron mine in West Cumberland', Ullcoats was eventually connected underground to its neighbour Florence Mine, together forming one of the last working iron ore mines in Europe.	Cumbria	Registered 1897; first shaft sunk 1900–1959 (winding-up); combined Florence-Ullcoats complex finally closed 2007	Iron
United Mines Once part of Gwennap's 'richest square mile on earth', this Cornish copper mine worked what was, under John Taylor, described as the richest copper lode in the world.	Cornwall	c.1780 (amalgamation of Ale and Cakes Mine, Wheal Cupboard and Poldory); profitable from 1822 under John Taylor–1857 merged into Clifford Amalgamated Mines, which closed in 1870; brief 1940s prospecting found nothing workable	Copper, Tin
Universal Colliery Two explosions, twelve years apart, at the same colliery — the second of them still the single worst mining disaster in British history.	Caerphilly	1891 (sinking)–1928	Coal
Unst Chromite Mines A narrow-gauge railway built in 1907 to carry the ore never carried a single passenger — and none of Shetland's few industrial railways survived, this one included	Shetland Islands	Chromite discovered by Samuel Hibbert in 1817; serious quarrying from 1824–1944	Chromite
Upton Pyne Manganese Mine Until 1810 this was the chief manganese producer in southwest England, shipped from Exeter Quay for the glass trade — and, as far as is documented, the first English manganese source ever worked.	Devon	Ore recognised c.1770; mining began March 1788–Probably by the mid-1820s	Manganese
Valleyfield Colliery Its coal spent the last thirteen years travelling to another county underneath the Firth of Forth before it saw daylight	Fife	1908–1978	Coal
Van Mine Briefly one of the richest lead mines in the UK during the 1870s boom	Powys	1862–1922	Lead, Silver, Zinc
Vane Tempest Colliery The shafts were sunk using the freezing process — deliberately freezing the ground solid around the shaft as it was dug, to hold back water and quicksand long enough to sink it safely.	County Durham	Sinking from December 1923; opened 1926–Last working shift 23 October 1992; closed 4 June 1993	Coal
Vigra Mine Vigra's own story has been almost entirely swallowed by its more famous neighbour: because the two mines were so often worked and recorded together, no one today actually knows how much gold Vigra produced on its own account.	Gwynedd	1833 (application); worked as copper mine 1825-1845; gold from 1860s–c. 1910 (little work after 1879)	Gold, Copper
Vitifer Mine (Birch Tor and Vitifer) Vitifer holds the distinction of outlasting every other tin mine on Dartmoor: by the time it finally closed in 1925, centuries after stream working first began on the site, it was the last one still standing.	Devon	documented from 1750 (Vitifer); 1757 (Birch Tor)–1925	Tin
Votty and Bowydd Quarry Votty and Bowydd's own history is really the history of two quarries becoming one, then being folded again into its neighbours after closure — a pattern of merger and absorption that runs right through Blaenau Ffestiniog's slate industry.	Gwynedd	Bowydd worked from c. 1800, commercial from 1833; merged with Votty in 1870–1963	Slate
Wanlockhead Scotland's highest village; mining museum on site	Dumfries and Galloway	13th century–1934	Lead, Copper, Silver, Zinc, Gold
Watcombe Clay Pits Torquay clay pits that founded the Watcombe terracotta pottery industry from 1869.	Devon	clay discovered c. 1865; Watcombe Terra Cotta Clay Company founded 1869–1962 (pottery closure)	Brick Clay
Wath Main Colliery The country park built on Wath Main's own reclaimed ground didn't even last as long as many of the miners who once worked there had spent underground — sold for housing barely a decade after it opened.	South Yorkshire	sinking began 1873; reached the Barnsley seam 1876–amalgamated with Manvers Main 1 January 1986; closed 25 March 1988	—
Wearmouth Colliery The deepest mine in the world when it opened in 1835; its site is now Sunderland's Stadium of Light	Tyne and Wear	1826-1834 (sinking)–1993	Coal
Welbeck Colliery The colliery's own workforce transferred to Daw Mill near Coventry when Welbeck closed — a 140-mile daily commute for some, until Daw Mill itself closed after a serious fire just three years later.	Nottinghamshire	Shafts sunk 1912; production from 1915–Last coal 11 May 2010	Coal
Wellesley Colliery Scotland's first pithead baths, and in 1938 the largest coal washery in Europe	Fife	1883-85 (as Denbeath); renamed Wellesley 1905–July 1967	Coal
Wellington Pit Built to look like a castle so it wouldn't spoil the view from Lord Lonsdale's grounds — and sealed in 1910 with 136 men still underground	Cumbria	1840–1933	Coal
West Chiverton Mine One of Cornwall's two greatest 19th-century lead mines, producing around 45,800 tons of lead ore and over 1.24 million ounces of silver between 1859 and 1886, with an unusually fine surviving engine house at Batter's Shaft.	Cornwall	1846 (as Ventongimps Mine); reopened 1856 as West Chiverton–1886 (underground working ceased 1882)	Lead, Zinc, Copper, Silver
West Stanley Colliery A deputy led thirty-four men through the dark, lost seven at the shaft, and sang the rest through the wait — twenty-six came out alive	County Durham	1832–1936	Coal
Westbury Ironstone Quarry A Wiltshire ironstone quarry whose flooded pits are still known locally as 'the mineholes', now protected as a geological Site of Special Scientific Interest.	Wiltshire	Ore discovered 1840s; Great Western Iron Ore Smelting Co formed 1857, works opened 1858–1933	Iron
Wet Earth Colliery Wet Earth Colliery gave James Brindley his start: the young millwright who solved this pit's flooding problem in the 1750s went on, within a decade, to become the driving engineering force behind the Bridgewater Canal and the birth of Britain's canal network.	Greater Manchester	1740s; formal working from 1751–1928	Coal
Wharncliffe Wood Ganister Mines A rock nobody outside Yorkshire had heard of that, once someone worked out furnaces loved it, became a whole local industry's namesake.	South Yorkshire	1860s–Around the end of the Second World War	Ganister
Wheal Baddon Rich enough in lead and silver in the mid-19th century to give its name to the hamlet of Wheal Baddon that still stands over the site.	Cornwall	1842–1872	Lead, Tin, Silver, Zinc
Wheal Basset (Basset Mines) The stone used to build Lyle's Shaft's grand 1879-80 pumping engine house came from demolishing four older, worn-out engine houses on the same sett — one generation of Cornish engineering quite literally built from the bones of the last.	Cornwall	worked from 1815 (as separate setts); Basset Mines company formed 1896–1918	Tin, Copper
Wheal Betsy The only standing engine house left on Dartmoor, saved from Army demolition plans in 1954	Devon	1740–1877	Lead, Copper, Arsenic, Silver, Zinc
Wheal Buller Wheal Buller's 1856 dividend record captures just how quickly Cornish mining fortunes could turn — the same mine that paid out more than any other in the county that year had, within two decades, run out of ground worth working at all.	Cornwall	worked from 1819–1875 (main); failed reworking 1928-1930	Copper, Tin
Wheal Busy The first Boulton and Watt engine in Cornwall pumped here — and the mine outlived its copper by half a century on arsenic nobody had wanted	Cornwall	16th century (earliest working); 1720s (copper production)–1924	Copper, Tin, Arsenic
Wheal Coates Iconic ruined engine house on the St Agnes cliffs	Cornwall	1802–1914	Tin, Copper
Wheal Cock The 1895 collapse of an underground dam here flooded the mine's richer ground faster than its engines could pump it clear.	Cornwall	Reopened 1778; amalgamated into Botallack Mine after 1841–Closed after flooding in 1894 and 1895; reopened 1906, finally closed 1914	Tin, Copper
Wheal Damsel One of a trio of Damsel-named setts worked together through the 19th century; the mine's name now survives only as a residential road built over part of the old ground.	Cornwall	1795–1872	Copper
Wheal Edward Wheal Edward's real claim to fame came long after it stopped being a copper and tin mine: pitchblende from its lodes was sent to Marie Curie, and in the late 1950s the Atomic Energy Authority came back to extract genuine uranium ore from the same cliff lode.	Cornwall	worked from 1821 (first returns); reopened 1863–1893	Copper, Tin, Uranium
Wheal Eliza An unsuccessful Exmoor copper and iron trial remembered today less for its ore than for the notorious 1858 murder whose victim was found in its flooded shaft.	Somerset	From 1845 (as a copper venture); examined for iron 1856-57–1858	Copper, Iron
Wheal Fortune Part of the disused mine is a Site of Special Scientific Interest, designated in 1991 for its geological interest, and a Geological Conservation Review site of national importance: its opencast exposes two distinct generations of tin mineralisation in one location, an unusually clear and instructive example for studying granite-related hydrothermal tin deposits in southwest England.	Cornwall	1855–1912	Tin, Copper, Arsenic, Tungsten, Zinc
Wheal Friendship Wheal Friendship is remembered less for its copper, which most Devon mines also produced, than for the young manager it made: John Taylor left Mary Tavy to become one of the most sought-after mining engineers in Britain, called in wherever a mine's owners needed the water-power and drainage expertise he first developed here.	Devon	late 18th century–1925 (surface tribute working to the 1950s)	Copper, Tin, Arsenic, Lead
Wheal Gorland A Cornish copper mine whose lasting fame rests on its oxidised upper workings, the type locality for five secondary copper minerals including liroconite and cornwallite.	Cornwall	1792–1864 (main working); brief reopening 1906-1909	Copper, Tin, Arsenic, Tungsten
Wheal Grambler The only mine engine house left standing in the parish of St Day, and a compact example of Cornwall's amalgamation era: three small, separately worked setts merged in 1834 into St Aubyn United Mines, which then worked on quietly for another sixty years.	Cornwall	By 1792, as East Wheal Sparnon–1893, as St Aubyn United Mines	Copper, Tin, Fluorspar
Wheal Grenville Wheal Grenville spent its first six years losing money badly enough to be sold off — and then went on to become one of the Camborne district's most consistently profitable tin mines for the next four decades, a turnaround owed entirely to going deeper and finding the Great Flat Lode's tin beneath the copper that had first disappointed everyone.	Cornwall	1820s (initial working); productive from 1850s; formal lease 1845–1920	Tin, Copper
Wheal Harmony Formed in 1816-17 from the amalgamation of Treleigh Wood Mine with several smaller workings near Redruth, exploiting the eastern extension of the Wheal Tolgus main lode.	Cornwall	mining recorded from at least the 1760s; formally as Wheal Harmony from c.1816-17–1879 (as Treleigh Wood Mine); a Mining Remediation Authority abandonment plan for the combined workings is dated 1864	Copper, Tin, Tungsten
Wheal Jane Site of the major 1992 mine-water pollution incident	Cornwall	1861–1991	Tin, Copper, Arsenic, Lead, Silver, Zinc
Wheal Jennings The only mine in an otherwise copper-dominated parish worked purely for tin, and the only one still being tried on any scale as late as the early 20th century.	Cornwall	Worked by at least the 19th century–Reworked unsuccessfully at the start of the 20th century; no exact final closure date found	Tin
Wheal Kitty The 65-inch engine that ended its days at Wheal Kitty in 1910 was already secondhand when it arrived — built in 1852 and first used at another mine entirely, it worked on at St Agnes for two more decades as the last beam engine the district would ever see.	Cornwall	documented from 1758; consistently worked from 1834–1930	Tin, Copper, Iron
Wheal Maid Wheal Maid's two very different lives — a profitable Georgian copper mine, then a late-20th-century tailings dump — have left it as one of the most scientifically studied contaminated mine sites in Britain, a real-world laboratory for how sulfidic mine waste weathers once nobody is managing it any more.	Cornwall	1782–1870s (mine); site used as a tailings dam 1970s-1980s	Copper, Tin, Arsenic
Wheal Martyn China Clay Works Cornwall's china clay industry once supplied half the world's kaolin; this site is now a working Victorian clay-works museum	Cornwall	1820s–1931 (pits); 1969 (pan kiln use ended)	China Clay
Wheal Mary Ann A Menheniot silver-lead mine whose 1845 founding was settled by a Chancery suit before it raised any ore, later worked to 250 fathoms under Captain Peter Clymo.	Cornwall	1845–c. 1875	Lead, Silver, Fluorspar
Wheal Owles Site of Cornwall's second-worst mining disaster after Levant — the 1893 flooding from the abandoned Wheal Drea, which killed twenty men and boys — and later a BBC Poldark filming location.	Cornwall	c. 1830 (undated earlier workings on the site predate this)–1893	Tin, Copper
Wheal Peevor Wheal Peevor's three engine houses, standing together exactly as they served three different jobs, make it one of the clearest places in Cornwall to see at a glance how a single mine's pumping, hauling and ore-crushing operations actually fitted together on the surface.	Cornwall	sett granted c. 1701; worked from the mid-18th century–1889 (main closure); reopening attempts 1911-18, 1938, 1950s all failed	Tin, Copper, Tungsten
Wheal Prosper Wheal Prosper's engine house, framed against Mount's Bay from Rinsey Head, is one of the most photographed mining ruins on the Cornish coast — a striking survival from a mine that, ironically given its name, never actually turned a profit.	Cornwall	circa 1860–1866	Copper, Tin
Wheal Trewavas Wheal Trewavas is one of only a small number of Cornish mines whose workings genuinely extended out beneath the sea rather than merely running close to the shoreline — a fact underlined by the manner of its closure, when the sea broke through into a tunnel being prepared for the miners' own annual dinner.	Cornwall	by 1834–1846	Copper
Wheal Union Amalgamated at least four earlier mines under one name yet was never once profitable across three separate working attempts spanning 34 years.	Cornwall	1848–1882	Copper, Tin
Wheal Uny Wheal Uny's paired engine houses, standing at right angles to each other above Redruth, are counted among the finest surviving groups of their kind anywhere in Cornwall — a rare case of both a mine's pumping and winding engine houses surviving together, built as a matched set.	Cornwall	worked from c. 1800–1893	Copper, Tin
Wheal Vor Wheal Vor's tin wasn't what finally beat it: the mine closed in 1848 with rich ground still unworked, brought down instead by twenty years of its own owners fighting each other in court over who owned the rights to it.	Cornwall	underground working from the 15th century; main 19th-century period from 1810–1911 (last major working); abandoned by 1967	Tin, Copper
Wheldale Colliery Wheldale went out as it had operated for over a century: the last colliery in Yorkshire still using pit ponies in 1972, and ten years later the last in the whole of Britain to run a steam locomotive on its own sidings.	West Yorkshire	sunk 1868; production from 1870–October 1987	—
Whitby Jet Workings Jurassic fossil-wood gemstone mined along the coast	North Yorkshire	1840–1920 (last mine, Cod Hill, near Guisborough)	Jet
White Grit Mine White Grit's Roman pig of lead, stamped for the Emperor Hadrian, is a rare case of a British mine site with a genuinely datable ancient find rather than mere local tradition of Roman-period working.	Shropshire	old workings recorded 1678; main periods 1830-1848–c. 1870	Lead
Whitecliff Ironworks A short-lived Forest of Dean blast furnace, financially ruinous but historically significant as the site of some of David Mushet's earliest steelmaking experiments.	Gloucestershire	Built 1798-1801, blown in 1801 or 1802–Iron production ceased by 1816, possibly as early as 1812	Iron
Whitehill Colliery Whitehill's real legacy isn't Scottish: the profits and experience Archibald Hood built here funded his move to the Rhondda Valley, where he became one of the founding figures of the South Wales coal industry his Midlothian miners never worked in.	Midlothian	worked from 1850; leased and developed by Archibald Hood from 1856–1961-62 (sources differ on the exact year)	Coal
William Pit Seven separate accidents at this one pit killed five or more men apiece — the last of them, in 1947, killed a hundred and four	Cumbria	Sunk from May 1804; first coal drawn 1805–Ceased production 31 December 1954	Coal
Wilsontown Ironworks Scotland's second coke-fired ironworks, the site where raw pit coal was first proven to fuel a Scottish blast furnace and where the 'spiral tuyere' was developed.	South Lanarkshire	1779–1842	Iron, Coal
Winsford Rock Salt Mine Europe's largest operating salt mine	Cheshire	from 1844	Salt
Winster Mines At its 18th-century peak, this lead-mining village may briefly have been the fourth largest town in Derbyshire — a status it owed entirely to lead, and lost entirely once the mines flooded out.	Derbyshire	by the 17th century–1938	Lead
Wolstanton Colliery For a time, this was the deepest hole miners anywhere in western Europe went to work down every day — 1,140 yards, achieved not by sinking one heroic shaft but by quietly merging three separate collieries into one underground system.	Staffordshire	1920–1986	Coal
Woodhead Mine Woodhead was a genuine one-man operation on an industrial scale: Colonel Cathcart didn't just finance the mine, he built an entire village around it, complete with a school and library, for a workforce of over 300 people.	Dumfries and Galloway	1838–1873	Lead, Silver
Woodhorn Colliery The pit is now the county archive: eight hundred years of Northumberland records kept in the buildings its winding engines stood in.	Northumberland	Sinking from 1894–1981	Coal
Woolley Colliery Arthur Scargill, the miners' leader who came to define British industrial politics in the 1980s, started out here as an ordinary young miner in 1953, at a pit by most accounts far from militant.	South Yorkshire	Established 1869–1987	Coal
Woolmet Colliery The tower house that gave the estate its name didn't survive the colliery that replaced it: undermined by Woolmet's own workings, Woolmet House came down in 1954, decades before the pit itself closed.	Midlothian	sunk 1898 (Gazetteer for Scotland) or 1904 (RAILSCOT) by the Niddrie and Benhar Coal Company–1966	Coal
Wren's Nest Limestone Mines Reached by nearly 3km of canal tunnel; still explored today by boat through the Dudley Canal Trust's underground tours	West Midlands	1780s (Castle Hill); c. 1805 (Wren's Nest tunnel)–1920 (mining); 1925 (quarrying)	Limestone
Writhlington Colliery Waste rock dumped at the pit head turned out, decades after the colliery closed, to hold the oldest damselfly fossil ever found anywhere in the world.	Somerset	Working by 1829–September 1973	Coal
Wroxton and Adderbury Ironstone Workings Opened not by ordinary industrial demand but on the direct instruction of the wartime Ministry of Munitions, which needed more British iron ore than the existing fields could supply	Oxfordshire	Adderbury workings from 1859; Wroxton quarry from 1917–1967	Iron
Wrysgan Quarry A workforce that once produced 3,000 tons of slate a year in 1904 had shrunk to just eleven men by the mid-1940s, still working the same underground levels for a fraction of the output — the quarry didn't fail suddenly, it simply wound down to almost nothing before finally stopping.	Gwynedd	1830s–1946	Slate
Wyndham Western Colliery Wyndham introduced South Wales's first miners' canteen offering a full hot meal service in 1942, and, in 1930, a system recording the colliery manager's own voice to warn men of hazards as their cage descended — modest, human-scaled innovations from a colliery whose Western half began with five men dying in a sinking explosion sixty years earlier.	Bridgend	Wyndham: sinking from 1865, shafts to Six-Feet seam completed 1868. Western: sunk 1873-75–January 1984	Coal
Yate Celestine Mines Ninety-five per cent of the world's celestine came out of these fields — and it was dug by farm labourers in the slack season	South Gloucestershire	1880s–1994	Celestine
Yesnaby Quarries A tsunami from the 1755 Lisbon earthquake reached this clifftop and nearly wrecked the quarry — and two centuries later the islanders themselves stopped a uranium mine here	Orkney	Millstone quarrying from an unknown early date, continuing to the Second World War–Quarrying declined after the Second World War	Freestone
Yorkshire Main Colliery The colliery was renamed from 'Edlington Main' to 'Yorkshire Main' while still being sunk — a rebrand that stuck for the next seventy-four years.	South Yorkshire	Sinking began 1909; opened 1913–11 October 1985	Coal
Ystrad Einion Mine Small lead, copper and zinc mine in Cwm Einion, worked intermittently from the 18th century to 1903; retains a rare surviving underground waterwheel.	Ceredigion	18th century–1903	Copper, Lead, Silver, Zinc
