The Princess Auguste Carolina mine or Auguste Caroline was a lead and silver mine in the Upper Harz Gangerzrevier . It was to the west of Wildemanner Straße ( L 515 ) and the innermost part of the mountain festival area near today's spa park in Lautenthal , a district of Langelsheim .
It is unclear whether the Guelph Princess Auguste Karoline von Braunschweig-Wolfenbüttel was the namesake, as her biographical data do not entirely coincide with the origin of the mine .
geology
The Princess Auguste Carolina mine built on the Bromberg ore resources of the Lautenthaler Gangzug , a hydrothermal vein structure in the north-western Upper Harz . In the area of the mountain town of Lautenthal, the corridor was mineralized over a striking length of almost two kilometers and in places down to a depth of over 600 meters with sulphidic, silver-containing lead and zinc minerals. The ore was located in an area between the Bromberger Schacht in the west and the Duke Ferdinand Albrecht pit in the east. The Bydgoszcz ore was separated from the Lautenthal ore under the Kranichsberg by a 100-meter-long dodging zone directly under the bed of the Innerste .
History and technology
Predecessor mining
The mining in Lautenthal began in a document around the year 1530. There are however, must be assumed that earlier in the Middle Ages Gangausbisse were visited on Kranichberg to-surface upcoming silver ores to win . Not far from the later Princess Auguste Carolina mine, first mentioned in 1533, the Grace God mine was built on Bramberge on the Bromberg ore mine .
Operation of the Princess Auguste Carolina Pit from 1757 to 1817
The pit Princess Augusta Carolina was first mentioned in 1757, then three were miners with the sinking of a shaft busy. For the year 1759, a weekly production of 18 tons of ore by eleven miners is documented. In 1764, the shaft had already reached a depth of 125 meters when a two-meter thick ore was exposed. The production rose to 60 tons per week and the workforce to 43 men.
With a shaft depth of 157 meters in 1768, the ore flow in the Ganges decreased. In the period up to 1786 only small and fluctuating amounts were extracted, up to a maximum of 6 tons / week. The number of employees fell again. From 1786, research work was only carried out sporadically by two miners. The depth of the shaft was 186 meters. From 1809 to 1814 an investigation of the deeper part of the corridor in the Princess Auguste Carolina mine field was carried out through a stretch from the Güte des Herr shaft .
In 1817 that was Berechtsame of the located on the eastern side of the Innerstetals pit Lautenthal lucky applied without there ever again dismantling began. The shaft itself remained open for many years and was only thrown out and filled in after the Lautenthalsglück mine was temporarily shut down in 1932 .
During the investigation work on the western Lautenthaler corridor train at the level of the Ernst-August-Stollen from 1954 to 1957, old structures of the Princess Auguste Carolina mine were visited on the cross passage 500 W. It was found that even larger amounts of zinc blende remained here. However , there was no further mining .

Current condition (2011)
The daytime facilities of the pit were located on the mountain festival site near the Lautenthaler Kurhaus. There you can still find the barred mouth of the day tunnel and the dump at the spa gardens. Members of the Mining and History Association Bergstadt Lautenthal from 1976 eV restored the first meters of the tunnel between 1988 and 1989 and set up a display board, a trolley and a reel there .
Parts of the former shaft building were used around 1932 for the construction of the show mine in the Upper Harz Mining Museum.
