Worked from at least the mid-19th century, with records indicating operations under the Bodidris Company before becoming the Creigiog Mining Company Ltd. The mine was active from 1884 to 1887 near Cefn-Coed, with earlier sale records in 1849 listing extensive machinery, including a Boulton and Watt 48-inch cylinder pumping engine. The mine was offered for sale in 1853 but continued operations until 1885.
