At Rest

Had a trip up Weardale yesterday to the Killhope Lead Mining Museum, a surprising place, interesting too if victorian engineering and mining floats your boat.

And now a very brief history - Lead ore in the North Pennines occurs in mineralised veins within the Carboniferous rocks of the area. Until the mid-19th century, exploitation of these ore bodies was mostly confined to surface excavations and vertical shafts. From 1818, mining in the area was controlled by W B Lead Co, a mining company established by the Blacketts, a prominent Newcastle family which had leased mining rights in Weardale from the Bishop of Durham.

In 1853, W B Lead began driving the Park Level Mine, which eventually intersected 11 mineral veins. As the mine developed, so did the surface workings. In 1858, a "mineshop" was built to accommodate the miners; the population density in such a remote area was very low and, until then, miners had been faced with a long daily walk to and from the mine. In 1862, storage bays ("bouse teams") were constructed, to store the raw lead ore (the "bouse"), and washing rakes were installed, in which water was used to separate the lead ore in the bouse from the waste material. In 1878, soon after the mine struck the richest of the veins, the Park Level Mill was brought into operation, to speed up the process of washing the ore. The main feature of the mill was a large waterwheel, the "Killhope Wheel".

Not long after the Park Level Mill came into use, the price of lead plummeted, rendering lead-mining in Weardale uneconomic and, in 1883, W B Lead closed all of its operations in the district. The Park Level Mine was taken over by another company, Weardale Lead, which continued to operate it until 1910, when production ceased. The mine was re-opened briefly in 1916, during the First World War, after which it lay derelict for over 60 years, during which time the buildings crumbled and any equipment that could be removed was salvaged for scrap.

Between 1818 and 1883, records show that W B Lead extracted over 31,200 tonnes of lead concentrates from the Killhope operations; between 1884 and 1916, Weardale Lead extracted a further 9,000 tonnes. Taking in the period before 1818, for which there are no records, it is thought that total output from Killhope may have exceeded 60,000 tonnes. In addition, 180 tonnes of zinc concentrates were recovered in the 1950s by treatment of some of the waste material.
