From 12th August 1845, the well-known Viennese jeweller Salomon Johann Nepomuk Goldschmidt took over the mine. A sophisticated business plan soon brought its “fruits” and mining became profitable after years. Among other things, Johann Nepomuk made a huge popularity of the jewel and its sale. He introduced a new system for the classification and evaluation of opal and employed approximately 350 miners in the mines.
