This museum opened to the public for the first time on 23rd May, 1998 with the intention of drawing attention to the mining history of the island.

In the entrance hall there is an impressive design showing how a volcano erupts and a large geological map of the island. There are illuminated panels showing mining today as well as tools and equipment from the mines and laboratories of the past.

On the first floor there are display cabinets with rocks and minerals from other parts of Greece and with the most industrially significant minerals of Milos today.

There are displays of fossils, obsidian,bauxite, alumina and aluminium. Photograps show us the now closed manganese mine at Vani, the sulphur mine at Paleorema as well as the place where mill-stones were quarried.

There is also a, tool found at Agia Kyriaki which was used during the Roman Period to grind minerals. The trunk of a large tree is on display which was found in a bentonite quarry at Aggeria 28 metres below the surface and the age of which is estimated at more than 2,000 years. The basement also offers surprises both scientific and cultural and a library of mining is being compiled.
