The Aurora mine is a former non-ferrous metal ore mine in the Bensberg ore district in Lohmar . The mine field was in the vicinity of Jexmühle between Bleifeld and Altenrath .
history
In the years 1825 to 1832, a deep tunnel was excavated from the bottom of the valley in the vicinity of the houses Jexmühle 18-24 on the left side of the Jexmühlenbach, in which, after 490 m, the St. Georg corridor was found . At 600 m you came across the Encounter corridor and at 640 m the Aurora corridor . The corridors were one to two meters thick and carried lead and copper ores , but also zinc blende . Work was resumed in the period from 1855 to 1858 with moderate success. In 1856, a processing plant was built near the Aurora tunnel , which was operated with water from the Jexmühlenbach and pit water from the tunnel.
A conversion application of February 24, 1866 for the length field Aurora in a square field led to the award on December 5, 1867 to the Honrath union. Excluded from this award, however, were the Längenfelder St. Georg , Encounter and Linné . On June 15, 1874, the individual fields Aurora, Aurora Tiefstollen, Wilhelm II, Maria, Gustav I, continuation, Silberhütte I and II and Johanna were consolidated . In this list, the fields of St. George, encounter and Linnaeus are no longer mentioned, so that it can be assumed that these were already consolidated at an earlier point in time. The Aurora mine field was awarded for lead, zinc, copper and iron ores . The owner was AG for mining, lead and zinc production in Stolberg and in Westphalia .
Experimental work has been carried out since 1905 and annual reports are available. In 1905, 10 workers cleared the Johann-Wilhelm-Stollen along its entire length and started the clearing work on the St. Georgs-Gang. The experimental work with 23 workers in the aisles of Joyful Hope, St. George, Encounter and Aurora had no results worth mentioning in 1906. In 1907 too, 17 workers had unfavorable results. In 1908, the exploration work with two workers was stopped in March. In 1909, six workers were busy improving the weather management in the Johann Wilhelm tunnel over a length of 60 meters. The end of the work came in 1910. The last time a worker had extended the tunnel by twelve meters. Small amounts of zinc blende and galena were found over the last 4.5 meters. The total production between 1855 and 1911 was around 12,000 t of lead and 1,060 t of zinc ore. The northern field was economically more productive than the other parts and was opened up to a depth of 130 meters .
St. Georg pit field
The St. Georg pit field was awarded on April 14, 1853. It was near sticks . The underground work carried out as early as 1834 showed, in addition to quartz, coarse lead luster as well as traces of spate iron stone , zinc blende and copper gravel.
Pit field encounter
The pit field encounter was muted on May 30, 1858 in the Oberhauser meadows near Hoferberg, Wolfberg and Hoven . The award took place on December 19, 1854. A 40-meter-long corridor was immediately excavated and a 16-meter-deep cavity was sunk. Copper, lead and zinc were found.
Linnée pit field
The Linné mine field was originally muted as Längenfeld on October 9, 1854 . After a field inspection on March 23, 1855, it was awarded on August 18, 1855 for lead, zinc and copper. It had an 18-meter-deep shaft east of Bleisiefen on the northern edge of Oberhaus bei Bleifeld. In 1855 50 hundredweight galena were promoted.
