The uranium was mined in open pits and in underground mines. The largest open pit called "Lichtenberg" is located near Ronneburg. Its initial depth was 240 meters; after being partly refilled, the depth was still 160 meters at an open volume of 80 million m 3 in 1990. After depletion of the ore deposits located near the surface, mining continued at this place to depths of 500 meters.
