Listed only where MineArchive's own research gives a reasonable evidential basis for the connection — not every mine where this geology might plausibly apply.

Mine	Region	Worked	Commodities	Connection
Poltesco Serpentine Works	Cornwall	Small-scale working from the early 18th century; factory built 1855-66–1893	Serpentine, Talc	(historical documentary reference) Poltesco worked the Lizard Complex serpentinite itself, as decorative stone and soapstone — the same serpentinised ultramafic host rock that carries podiform chromite elsewhere, though no chromite was worked here.
Unst Chromite Mines	Shetland Islands	Chromite discovered by Samuel Hibbert in 1817; serious quarrying from 1824–1944	Chromite	(well documented example) Unst's chromite occurs as isolated pods within serpentinised ultramafic rock, part of an ophiolite emplaced during the Caledonian orogeny — the defining example of this deposit type in Britain.
