Basalt is a hard, dense igneous rock formed from volcanic activity as cooled lava. We can find it on the black sand beaches of Hawaii to Sheepeater Cliffs in Yellowstone, in the U.S. to the Giant's Causeway in Ireland. We often think of it being pitch black, but it does vary in color depending on the local geology in which it formed.

The mine has been exploited since 1980 and since 2019 it has been exploited by "Artsate Syun".The reserves of the mine are about 2 million m³.Mine productivity can reach up to 400m³ per day.

Basalt is a type of volcanic rock that is formed from the solidification of molten lava. It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava. Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor.

The primary formation of the mine is a rhyolite and obsidian flow full of gas pockets. The Opal Solution or silica, was a secondary deposit carried by geyser activity. As a result of several eruptions over a period of time, the opal lays in layers. Most of the layers are thin, resulting in some of the most beautiful triplet opal in the world.
