Holmslinn Mine

Overview

A Northumberland lead mine on the Blackett Level drainage system, notable for adopting pioneering W. G. Armstrong hydraulic winding and pumping technology in place of steam power when its shaft was sunk in 1855.

History

Holmslinn Mine stood on the left bank of the River East Allen near Sinderhope in Allendale, its 70-metre shaft sunk in 1855 as the second along the Blackett Level from its portal in Allendale Town, part of the same drainage system serving the already-published Sipton Mine. Lead mining here, under the ownership of the Blackett and Beaumont families -- who dominated Allendale's lead industry through the 18th and 19th centuries -- began in 1856 and continued into the late 19th century. Holmslinn was chosen as the site to showcase pioneering hydraulic technology developed by the engineer W. G. Armstrong for winding and pumping, in place of the steam power used elsewhere in the district. Ore raised at Holmslinn was carried away for processing and then smelted at the Blackett-operated Allen smelting mill in Allendale.

Geology

Lead of the Allendale orefield; the vein is not named on the record, and the ore went to the Blackett company's Allen smelting mill.

Workings

Worked via a 70-metre shaft using W. G. Armstrong's pioneering hydraulic winding and pumping technology in place of steam power; a stone-built wheel pit housed a large overshot water wheel, its surplus water carried north to the river via a stone-lined tail race.

Closure

Worked until the late 19th century.

What remains

A Scheduled Monument and Grade II Listed Building, part of the Land of Lead and Silver project managed by the North Pennines National Landscape; the stone-built wheel pit survives.

• Blackett Level — The Blackett Level was driven to drain the shafts at Holms Linn among others, and the mine is named on the level's own account.
• Sipton Mine — Both sat on the same drainage system and were owned by the same families, Blackett and Beaumont.
