Mine	Region	Worked	Commodities
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–May 1884 (main); failed reopenings 1891-93, 1911-13	Lead, Silver, Zinc, Barite
Tannochside Colliery Its owner opened a brand-new brickworks right next to the colliery in 1936, recruiting its entire workforce locally to turn out 150,000 bricks a week.	North Lanarkshire	Worked from 1870 under the Monkland Iron Company.–Closed in September 1945.	Coal
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
Thornthwaite Mine Unusually for a Lake District lead mine, Thornthwaite kept working through the price slump of the 1870s-80s and was worked continuously from 1900 to 1920, reaching 85 fathoms by 1912 with a workforce of around 90.	Cumbria	1780s–Sustained working ended around 1920-21	Lead, Zinc
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, Barite
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)–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–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 working ended around 1925	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–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	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	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
Trevaunance Mine Trevaunance Mine is said to have paid its adventurers £100,000 in dividends over its working life -- a fortune built on ground that never needed to be sunk much below 60 fathoms.	Cornwall	1843–1887	Copper, Tin
Turnavore Mine A 60-inch pumping engine is a serious piece of Cornish engineering -- and Turnavore's was thought valuable enough that when the shaft no longer needed it, the engine itself was moved next door rather than scrapped.	Cornwall	1837–1895	Tin, Copper
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–Nos. 6, 7 and 8 closed 1936; No.9 closed 1960	Coal
Tymawr East Quarry Worked as an open pit and hillside quarry on the south side of the road between Nantlle and Talysarn, one of a paired East and West working of the same name.	Gwynedd	Opened around 1860.–Closed around 1910.	Slate
Tymawr West Quarry Grew from a pit-and-hillside working into a full open pit served by a Blondin cableway as work progressed downward, yet even at its peak in the 1860s never employed more than about 40 men and produced well under 1,000 tons of slate a year.	Gwynedd	Active by the 1860s.–Closed during the 1930s.	Slate
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
Tynehead Mine A lead mine in the Alston Moor orefield, at the head of the South Tyne.	Cumbria	1854–1873	Lead, Copper
Tywarnhayle Mine Its 1906 flotation plant is described by Cornwall's own Historic Environment Record as the remains of 'the world's first commercial froth flotation plant' -- an extraordinary claim for a small, commercially unsuccessful Cornish revival, and one this record treats with real caution rather than repeating as fact.	Cornwall	1750–1864	Copper, Tin
Ubley Rake One of two large rakes -- open lead workings over 100 metres long and up to 10 metres deep -- that anchor the historic Charterhouse lead field on Mendip, worked since Roman times and reworked in the 19th century for its own lead-rich slag.	Somerset	Roman times (industrial phase from 1844-47)–1885	Lead
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; profitable from 1822 under John Taylor–1857 merged into Clifford Amalgamated Mines	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, Barite
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
Vivian Quarry Its flooded former workings, up to 18 metres deep, are now a popular diving centre where divers can explore surviving quarry huts and equipment still standing on the submerged quarry floor.	Gwynedd	Opened in the 1870s as a self-contained department of the Dinorwig slate quarry.–Slate working finished in 1960.	Slate
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
Vron Quarry Named its own De Winton locomotive 'Vron' in 1878, and survived long enough to run a second, secondhand locomotive from a neighbouring quarry -- a 1904 Hunslet, originally built for Moel Tryfan Quarry, acquired in the 1900s.	Gwynedd	Working by 1815 under John Evans–Worked, with interruptions, until 1950.	Slate
Walsall Wood Colliery The men who sank Walsall Wood Colliery had never run a mine before in their lives -- yet inside three years they had driven the deepest shaft anywhere on the Cannock Chase coalfield.	Staffordshire	1874–1964	Coal
Wanlockhead Scotland's highest village; mining museum on site	Dumfries and Galloway	13th century–1934	Lead, Copper, Silver, Zinc, Gold
Warren Moor Mine A short-lived Kildale ironstone mine whose unused 1856-57 chimney -- built before mining even began -- is the only one of its kind left in the UK.	North Yorkshire	1866–1874	Iron
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
Watergrove Mine Its 1794-95 engine house was the site of one of the earliest Newcomen atmospheric engines in the Peak District, later archaeologically excavated by the Peak District Mines Historical Society -- and its 1836-46 replacement engine involved the same engineer, William Wyatt, later responsible for the ill-fated pumping engine at the archive's own High Rake Mine.	Derbyshire	A sough-driving venture was underway by 1746–The mine's final Annual General Meeting was held in February 1872.	Lead
Waterside Colliery Not a single shaft in its own right, but the operational hub -- washery, locomotive shed and railway network -- serving a whole district of numbered Dalmellington Iron Company coal and ironstone pits, today preserved as a heritage railway.	East Ayrshire	1848–1986	Coal, Iron
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
Wembley Ironstone Quarry Ore from this pit fed the same Teesside furnaces that produced the steel for the Sydney Harbour Bridge -- a very long supply chain from a Northamptonshire hillside.	Northamptonshire	1924–early 1940s	Iron
West Cannock Colliery A single company sank five separate pits here over 45 years, and the very last of them -- No. 5 -- ended up outliving the first four combined by a wider margin than the gap between when they'd all opened.	Staffordshire	1869–1982	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 Rigg Opencast A rare surface exposure of the North Pennine Orefield's Slitt Vein: 19th-century ironstone quarrying was worked around the vein rather than through it, leaving it standing today as a vertical 'rib' running down the centre of the quarry.	County Durham	uncertain (fluorite/galena); late 19th century (ironstone)–uncertain (SSSI designation 1968)	Iron, Lead
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
West Stonesdale Mine Its engine house held a genuinely rare hydraulic engine -- powered by water pressure rather than steam -- doing triple duty on winding, pumping and ventilation, at a time when such engines were still a novelty in the north of England.	Yorkshire	Built from 1850 to access the western end of the Blakethwaite vein.–Abandoned in 1861 after the vein proved barren	Lead
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–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
Wetshaw Mine Named for a cluster of workings on Reeth High Moor -- Wetshaw Level, Wetshaw High Whim and the Black Whim shaft -- whose surviving trackways were specifically studied by local archaeologists using satellite and aerial imagery to establish how ore was once moved across the site.	Yorkshire	uncertain–No reliable closure date has yet been located.	Lead
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
Whaw Mine The hillsides around the hamlet are still scarred by hushes -- artificial floods released to strip away topsoil and expose the ore beneath -- while a Roman lead 'pig' stamped with the Emperor Hadrian's name has been found locally, alongside a 1285 record of the Lord's mine in the dale turning a profit of £4.	Yorkshire	Lead was worked in Arkengarthdale from at least medieval times–uncertain; Arkengarthdale's mines as a whole closed by 1912.	Lead
Wheal Alfred Once one of Cornwall's richest copper producers, raising some 175,000 tons of copper ore between 1801 and 1864 -- today remembered by geologists chiefly for its fine mimetite and pyromorphite mineral specimens, as a Site of Special Scientific Interest and Geological Conservation Review site.	Cornwall	by 1801–uncertain	Copper, Tin
Wheal Andrew Also recorded under the name Friendship Mines -- a coincidental name shared with, but entirely unrelated to, the well-known Wheal Friendship already documented on this archive at Mary Tavy in Devon, a common mine name reused independently in both counties.	Cornwall	Absorbed into the expanded United Mines group at some point after the group's initial 1780 founding.–Closed around 1870 as part of Clifford Amalgamated Mines	Copper
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 Clifford Struck the United Mines group's notorious 'Hot Lode', where water at around 100 degrees Fahrenheit poured continually over the miners working it, cutting productivity so badly that men could barely manage an hour's work in a day.	Cornwall	Working independently by 1835, before being absorbed into the wider United Mines group.–Merged into Clifford Amalgamated Mines in 1861	Copper, Tin
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 Cupboard The third and final of the three founding mines of United Mines -- alongside the already-published Ale and Cakes Mine and Poldory -- whose combined workings, once rebuilt by the engineer John Taylor in the 1820s, struck what was at the time the richest copper lode in the world.	Cornwall	Working before 1780–Closed around 1870 as part of Clifford Amalgamated Mines	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 Drea Its own long-flooded old workings were the ones neighbouring miners broke into on 10 January 1893, causing the already-published Wheal Owles flooding disaster that killed nineteen men and a boy.	Cornwall	1790s; merged into Wheal Owles c. 1859–Worked as part of Wheal Owles until 1884	Tin, 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 Fanny One of the five original setts -- alongside Wheal Maria, Wheal Anna Maria, Wheal Josiah and Wheal Emma -- that together made up the already-published Devon Great Consols, once the world's largest producer of arsenic.	Devon	Started in 1845 as one of the original setts making up Devon Great Consols–Closed with the rest of Devon Great Consols in 1903	Arsenic, Copper
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 Frementor A worked-out vertical tin deposit here left a 'gunnis' -- an open void some 4 metres wide, 70 metres deep and 200 metres long -- now fenced off as a striking, if hazardous, feature of the site.	Devon	opencast, date uncertain; underground working resumed c.1915–1930	Tin, Tungsten
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–1879 (as Treleigh Wood Mine)	Copper, Tin, Tungsten
Wheal Hermon A map dated 1560 already shows this mine as an established working called 'Hermeno' -- meaning tin was already being pulled out of the Cot Valley here before Elizabeth I had even been crowned.	Cornwall	1560–1816	Tin
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	Tin
Wheal Jewell The large 'S'-shaped reservoir that now dominates the site was built directly over the mine's old gerts (open-cast workings) in 1936, destroying most of the surviving remains, to serve as a header tank for the Mary Tavy hydroelectric scheme.	Devon	Comprises workings on Kingsett Down dating to the late 18th century–Mining ceased around 1924, with only limited reworking in the 1930s	Tin, Arsenic
Wheal Kine Diamond tin -- ore pure enough to go straight to the smelter with no dressing at all -- was rare enough that Polberro's version of it became the thing the whole sett was known for.	Cornwall	1837–1895	Tin, Copper
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 Pell By 1750 this ground was producing more tin than the local packhorses could actually carry away -- a genuine bottleneck of success rather than the usual mining-district story of scarcity.	Cornwall	1750–1895	Tin
