Description and Identifying Characteristics Its perfect cubic cleavage, metallic luster, lead-gray color, and relative softness readily distinguish galena from most other metallic minerals. Perhaps its most distinctive feature though, is its very high density (high specific gravity). Once you pass the locality [Nontron] on the D675 take the D3 in the direction of Saint-Estèphe, where you will find on the left remains of prospective searches with baryte, and sometimes galena crystals as well. At the exit of Nontron towards Saint-Pardoux on the D707 [there are] workings with amphibolite, galena, muscovite, and tourmaline."The formula for circumference of a circle is 2πr, where “r” is the radius of the circle and the value of π is approximately 22/7 or 3.14. The circumference of a circle is also called the perimeter of the circle.Galena, also called lead glance, is the natural mineral form of lead sulfide . It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite.

Other/historical names associated with this locality: Balmat #3; St. Joe No. 3 Mine. A Zn-Pb mine in a sulfide orebody. No. 3 mine vertical shaft sunk was to 900 feet in 1951. No. 3 mine operated 1951-1985.Easily recognized by it good cleavage, high specific gravity, softness, and lead-gray streak, this mineral is the primary ore mineral of lead. It is a very common sulfide that has been worked for its lead content as early as 3000 BC. The name is derived from the Latin galena, a name originally given to lead ore.
