The mining evidence here is alleged to be of 19th-century date in the HER, but this is not correct as Pennant (1991, II, 8), writing in the second half of the 18th century, mentions long trenches in the locality from which he believed iron ore had been dug and to which he ascribed an early medieval date, demonstrating their antiquity at that time. He also
noted (1991, 14) that Hugh d’Avranches, Earl of Chester from 1071 to 1101, enjoyed a portion of the mines of iron ore found in Rhuddlan manor, which then included Marian Ffrith. It seems likely that the iron mines on Moel Hiraddug also fell within the manor.
Unlike Moel Hiraddug, where much of the evidence remains relatively undisturbed, most of the mining traces on Marian Ffrith have been obliterated by land improvement. There is a partially filled-in openworking at SJ 0718 7798 that seems to be the only survivor of the features seen by Pennant. (Hankinson, Britnell & Silvester 2012).
