The mine was discovered in 1968 by three Galicians who gave their name (from their surnames SEñarís, RAma and BALboa) to the concession and who found it while exploring these mountains in the Pico Sacro area in search of "seixo" (from the Galician: hard white rock) of good quality.

RM2497   Aluminium

Bulla Island, Caspian Sea, Gobustan, Azerbaijan

Small particles containing grains of native aluminum, an extreme rarity. In the images we can see that they are associated with magnetite. They most likely contain akdalaite, an oxide hydroxide of aluminum, which we have not confirmed due to the limitations of the electron microscopy technique. We will send report to the buyer.
The Bulla or Boulla is a mud volcano on the island of the same name, in the Baku archipelago, a few km SE of the city of Baku. The most intense eruptions occurred in 1857 and 1940, when erupting breccia volumes reached a few million cubic meters. The most interesting mineralization (native metals, akdalaite) is related to the ejection of the 1947 eruption.

RM2455   Balangeroite

Poggio San Vittore mine, Balangero, Torino, Piemonte, Italy

Really fine specimen for this rare species. The balangeroite is a magnesium, iron anfd manganese silicate, only found in a few places worldwide. The serpentine Poggio San Vittore quarry, which were the best samples has been found and it is the type locality for the species, is abandoned since 1990. The mineral usually appears included in the serpentine matrix and only few fibers are aerial. In this specimen, fibers are totally aerial and with a good length.
