In 1902, under French possession, the company "Société des mines d'etain de Cao Bang" (Cao Bang tin mine) began exploiting the mine until Vietnam’s independence. Tin and other minerals thereafter are mined at Tinh Tuc and adjacent areas until today. The development of this group of mines has strongly influenced the development of Tinh Tuc Town at the beginning of and during the 20th century.
Similar to other mineral deposits around the Pia Oac granite massif, the gas rich hot magma that intruded (c.85-95 million years ago, Cretaceous period) into the limestone (containing Crinoids, formed under shallow and warm marine conditions c.360-270 million years ago, Carboniferous-Permian period) had resulted in tin and other related minerals.
Tin is of high economic value. It is a silvery-white metal that is soft, malleable and fairly resistant to corrosion. Its extraction and use can be dated to the beginnings of the Bronze Age around 3000BC. When first used it was mixed with copper to produce bronze, which is a very resistant metal. After that, because of its low toxicity, tin was used for houseware manufacture (plate, pots etc.). Today alloys made from ... View more
