"50 m west of the Erlenbach estate, between the Lütticher Straße and the Herzogenweg, excavations were started in November 1940 by the "Stolberger Zinc Works". 20–30 miners were working in three shifts.
The required tools and machinery were usually dismantled at the mine site in Lontzen and transported by heavy horse-drawn wagons to the Erlenbach site.
As for the mine site itself, we can say that it was so small that it barely stood out from the street. The high shaft tower with two baskets was the most striking.
In the occupied hangars, built from corrugated metal plates, several materials were stored. These hangars served as engine room and forge, as pumping chamber and ore storage. The compressor and the transformer were also housed within.
100 meters to the northwest stood the dynamite bunker, which was buried in the ground.
The air shaft was located about 50 meters to the north.
In the first year, the shaft had reached a depth of 15 meters. At this level, a bit of "blende" was mined. The detected ore was found as a layer 15 cm thick, a meter wide and 15 meters long.
After further drilling in 1941 to a depth of 35 m, the water suddenly rose by 9 m. They decided to install heavy pumps to pump the water out of the shaft.
The mined ore was dumped on the local "Halde" (dump).
Note here that no cargo of "blende" was ever carried off-site.
The works were continued until the end of the war.
Immediately thereafter, the shaft was closed and filled up, and all the materials stayed behind on the grounds."
