- Greenside_Mine abstract "Greenside Mine (sometimes referred to as Greenside Lead Mine) was a successful lead mine in the Lake District of England, near Glenridding village, in the parish of Patterdale. This is now in Cumbria, but during the working life of the mine it was in the former county of Westmorland. Between 1825 and 1961 the mine produced around three million long tons (3,050,000 tonnes) of crude ore, which yielded some 200,000 long tons (203,000 tonnes) of lead and two million ounces (57 tonnes) of silver. Unusually for a 19th-century metalliferous mine in Britain there are very full records of its activities dating back to 1825.The mine probably opened during the second half of the 1700s but closed some time before 1819. In 1825 the Greenside Mining Company was formed and reopened the mine. The mine was very profitable until 1880 when the price of lead fell and it became more difficult to make good profits. Many other lead mines closed, but the company continued to work Greenside until 1935. Electricity was introduced to the mine in the 1890s, and it became the first metalliferous mine in Britain to use electric winding engines and an electric locomotive. In 1936 the Basinghall Mining Syndicate Ltd. reopened the mine, and turned it into the largest producer of lead ore in the United Kingdom during the 1940s. The mine closed in 1962 after lead reserves had been exhausted. Just before it closed the mine was used by the Atomic Weapons Research Establishment (AWRE) to conduct an experiment in detecting seismic signals from underground explosions.All the ore produced by the mine came from the Greenside Vein, a mineral vein which filled a geological fault running in a north-south direction under the east ridge of Green Side. This is a mountain in the Helvellyn range, near the head of Ullswater. Mining activities traced this fault for a length of 3,900 feet (1,200 m) and to a depth of 2,900 feet (880 m). Four areas of the vein, known as ore shoots, contained galena, an ore of lead which also contained small amounts of silver. At first the ore was mined simply by driving adits into the mountain-side. To access ore at greater depths, two longer levels were driven from lower down but further away, and then a series of shafts were sunk within the mine. The lowest point in the mine was roughly 100 m below sea level, where the andesite rock rested upon underlying shales in which the fault had not been mineralised.Two processing mills were built to crush the ore and separate out the galena from it, and the mine had its own smelt mill between 1828 and 1917. After that it was more economical to sell concentrated galena to a commercial smelter.".
