The pit Fischbacher work was a iron ore - and lead ore mine in the municipality Niederfischbach in district Altenkirchen in Rhineland-Palatinate .

In the 15th century the rights to mine lead ore were granted, and from 1880 silver was also mined. A company was founded around 1770, it consisted of a consolidation of the individual pits Krautgarten, Blumengarten and Wendelseifen.

Between 1860 and 1897 the mine was sold three times:

• 1860: by a Belgian mining company

• 1878: by an English mining company

• 1897: by "Niederfischbacher Berg- und Hüttengesellschaft"

In 1869 they started to sink a shaft. However, proper civil engineering did not take place until 1869. The shaft had a size of 2.54 × 0.9 m and a depth of 390 m. From 1893 it was called the old shaft, after a second shaft had already been sunk in 1880.

This was 465 m deep. The total depth of the pit was 510 m, on which 12 levels were distributed; up to 350 staff members worked in it. In 1869 the mine produced 12,388 t of spate iron stone, 71 t of lead ore and 92 t of copper ore.

In 1888 the mine was connected to the Betzdorf-Olpe railway. In 1897, 9,702 t of iron ore were still being mined. In 1901 it went bankrupt and was shut down in 1902. Two years later, the mine workings were finally given up. A total of 212,562 t of iron ore and 34,700 t of silver-bearing lead ore were mined.
