The ironstone mine at Skinningrove (also known as Loftus mine) was opened on 7th August 1848, producing ironstone for shipment by sea to Bolckow and Vaughan’s Witton Park ironworks[1]. The mine's largest output of ironstone was in 1881, when it reached 654,000 tons. In 1896 the mine employed 781 people (676 below ground, 105 above ground).[2] The mine was closed in 1958.ncG1vNJzZmibn2Kwtr7ArZxnppOhe6Kvja6iaKubnruvtc2gqaiulWK2s7vNrKuoppViuqq6xGg%3D
