Bardon Hill Quarry is a 58.2-hectare (144-acre) geological Site of Special Scientific Interest east of Coalville in Leicestershire.

[1][2] It is a Geological Conservation Review site.

[3][4] This quarry has been operated for over 400 years and produces three million tonnes of rock a year, 15% of UK output.

It exposes rocks from an andesitic Precambrian volcano, similar to the 1995 Montserrat eruption, about 570 million years ago.

There are veins of quartz containing copper and gold.
