It was not until 1859 that renewed interest was shown in the mines, when Andreas Cordellas was sent to ascertain the likelihood of reopening them. The report given to the Greek government was evidently a glowing one regarding the reworking of the ancient smelt slag. The Greek Metal Works Company of Lavrion was set up in 1873 with the purpose to recover the metals still held in the poorly smelted slags. The Greek company continued to process the old smelt slag until 1917. It’s at the same time (1875) when this company began work on the recovery of metals in the ancient slags, a French company called Compagnie Francaise des Mines du Laurium took an interest in the remaining orebodies in the area. The mines came into the ownership of Giovanni Battista Serpieri (1832-1897), after whom the mineral Serpierite is named. Not only did the French company extend development on known ore bodies, but they also discovered new reserves. Mining in the area continued until 1982 when all work was stopped and the mine closed for the last time.
