Geology


Description

The show mine Grube Silberhardt is run by the Förderverein zur Erhaltung der Bergbau- und Hüttentradition e.V., a non-profit association. It was excavated by volunteers from 1997 and offered guided tours for the first time in 1999. From 2000, the first mine locomotive was ready to run again. The volunteers founded the association in 2002 and opened the mine the following year. At the same time, a 1.7 km-long Bergbauwanderweg (mining trail) with 14 stations was laid out, leading to various mine entrances, a furnace and a charcoal kiln. In 2017, a mining history exhibition was added to the show mine. The association is still actively expanding the show mine. At the moment, they are expanding the mineral exhibition and the mining history exhibition, and restoring a rope pulley which was donated by the Ruhrkohle AG (RAG).

Mining of silver-bearing ore began at this site as early as the 13th century. However, few details have survived from that time, but it is likely that only silver was mined. The only known fact is that mining ceased during the Thirty Years' War, between 1618 and 1648. Mining was resumed in 1752, but seems to have ceased again after some time.

The main phase of mining began in 1808, when Johann Caspar Rumpe, the mayor of Altena, acquired the mine. He sold it on to the miner Metzger as early as 1810, but after a partial collapse he bought it back again. In 1819, large quantities of silver-bearing galena were extracted and the Bröler Ironworks was converted for the smelting of lead and silver ore. In 1824 the Bröler Ironworks was extended, and mining seems to have taken off, presumably through improved smelting and the additional use of the lead content. The mine also received a waterworks in 1824; the increased mining made drainage necessary. In 1825 another stamping plant was built in Rosbach (Sieg). But in 1833 there was a miner revolt, and in 1834 mining ceased. This was probably not only due to staff problems, but also to the first investigations of the Sieg for contamination. It can be assumed that either environmental protection measures or compensation payments were already pending at that time.

In the following, the mine was reopened several times and closed again soon after, with changes of ownership occurring in quick succession. From 1859 to 1861 it was operated by small companies, and in 1863 by a joint-stock company Silberhardt en Jucht founded in Amsterdam. In 1873 a joint-stock company Ertsdelveriy Amsterdam was founded, shares with a nominal value of 150,000 guilders were issued, and in 1881 the mine was closed again. In 1884 a Mr. Dahm founded the 100 Kuxe Gewerkschaft Silberhardt, in 1892 the consolidation also took place and in 1900 the mine was opened. The only strange thing was that it produced nothing. In 1920 the Thyssen steelworks took over the mine, in 1924 a Mr Käsgen took over the processing plant and the mine, and in 1926 the property was sold by compulsory auction to the Vereinigte Stahlwerke. They actually produced from 1930 to 1936. In 1953 Erzbergbau Siegerland acquired the mine, and in 1965 Barbara Rohstoffbetriebe. All in all, the mine seems to have been not very profitable, and to have served primarily as a money pit for investors. With the rather impressive list of owners and bankruptcies, one can probably also suspect fraud. No mining seems to have taken place after 1936; the later owners merely secured the option.
