Cambokeels Mine Cambokeels' incline was built during the First World War by German prisoners of war — a small, easily overlooked detail that ties a routine Pennine fluorspar mine directly into the story of the war being fought at the same time on the other side of Europe.	County Durham	1868–1989	Fluorspar, Lead
Cambria Mercantile Colliery A small Ystalyfera anthracite slant of 1905 that became Ynysgeinon around 1915; its stripped powerhouse and winding house still stand beside a footpath.	Neath Port Talbot	1905 (renamed Ynysgeinon c.1915)–1921	Coal

Cannock and Leacroft Colliery A colliery that started life under one name and closed under a merged one now lies, fittingly, beneath a landfill -- one kind of buried material giving way to another.	Staffordshire	1874–1967	Coal
Cannock Chase No. 4 Pit A Chasetown pit where a hemp marker on the winding rope, used for want of an indicator, hid the wear that killed six in 1868.	Staffordshire	—	Coal
Cannock Chase No. 8 Colliery By the time it closed, No. 8 wasn't just one pit among the Cannock Chase Colliery Company's ten -- it was the last one left, having quietly absorbed its neighbour's workings a decade before its own turn came.	Staffordshire	1868–1962	Coal

Canonbie Colliery The one substantial pit of a small, half-hidden coalfield on the Scottish border.	Dumfries and Galloway	1854–1922	Coal

Caphouse Colliery Home to the National Coal Mining Museum for England; its shaft may be the oldest still in everyday use in Britain	West Yorkshire	1770s-1780s–1985	Coal
Caplecleugh Mine A dividend of £10,000 was reportedly obtained in a single year under its earliest recorded operator, and the mine's fortunes later turned entirely on zinc rather than lead: the London Lead Company left large amounts of zinc ore behind as uneconomic, only for the Belgian Vieille Montagne Zinc Company to return in 1896 and work the vein specifically for it.

Caradon Hill Medieval and Post-Medieval Mines A medieval field system buried beneath the later mines is intact enough to show exactly how farming here adapted to the slope and altitude -- and how mining, when it arrived, expanded straight into that same working landscape.

Cardowan Colliery Over 50 men are recorded as having died at Cardowan across its working life, yet the explosion that most directly hastened its closure — in January 1982 — killed no one at all, injuring 25 severely enough that the colliery was shut down until the cause could be established.	North Lanarkshire	From 1924 (sinking)–1983	Coal

Carn Galver Mine For all its Victorian investment — seventy miners, a shaft sunk to 130 fathoms, two purpose-built engine houses — Carn Galver's total recorded output across its working life came to just 150 tons of black tin, a genuinely modest return for the scale of effort put into it.	Cornwall	Early 19th century–1875	Tin

Craigend Colliery, Maddiston Carron Company's Maddiston pit, redeveloped from 1906 into one of Stirlingshire's largest and closed in 1935; its bing became bricks and its welfare scheme gave the village a golf course.	Falkirk	1854–November 1935	Coal, Ironstone

Creswell Colliery One of the worst British coal-mining disasters of the post-war era began with a single piece of wedged ironstone tearing a conveyor belt — the resulting fire's fumes killed 80 men who could not escape by the mine's only usable return airway.	Derbyshire	From September 1894 (sinking)–20 September 1991	Coal

Gwynedd	1846–1930	Slate
Croft Granite Quarry Local tradition holds the site was worked as a Roman granite quarry in the 1st century AD for road and bridge foundations, though this claim lacks scholarly corroboration and should be treated as tradition, not established fact.	Leicestershire	from 1868	Granite
Croft Pit, Whitehaven A Lowther pit of 1774 whose 1831 explosion left no survivor in the district where it fired, and whose site became the Ladysmith Pit.	Cumbria	1774–c.1905 (renamed Ladysmith Pit)	Coal

Cumbria	By 1864–1925 or 1926	Iron
