MD-213096 - Chalcophanite - - Archived Cole Mine (Cole shaft; Cole No. 3), Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA small cabinet, 5.5 x 4.2 x 3.4 cm.
5.5 x 4.2 x 3.4 cm. Chalcophanite is a rare zinc, iron, manganese hydroxide. This fine, 3-dimensional, mammilary crust from the Cole Shaft at Bisbee is composed entirely of sparkly, purplish-black chalcophanite botryoids. The very rich Cole Shaft produced ore intermittently from 1905 to 1975. Complete all-around and pristine, with only contacting at the base. Ex. Mark Bandy and Dave Stoudt Collections. Mark Bandy was a very prominent American mining engineer and mineral collector who died in 1963.
MD-230619 - Willemite, Chalcophanite, Hemimorphite - - Archived Potosí Mine, Aquiles Serdán, West Camp, Santa Eulalia District, Mun. de Aquiles Serdán, Chihuahua, Mexico large cabinet, 15.8 x 10.0 x 6.2 cm.
15.8 x 10.0 x 6.2 cm. A fine, rare, large cabinet combination specimen from Santa Eulalia and the Dave Stoudt Collection. Both sides of the vuggy, 3-dimensional, very sturdy, sintered gossan matrix are richly covered with lustrous, translucent, gray willemite botryoids. The scattering of glassy hemimorphite blades to 1.5 cm is an elegant accent to the botryoidal willemite. Chalcophanite is an uncommon zinc, iron, manganese oxide, but is very rare at Santa Eulalia. The large "V" of sparkly, grape-like clusters of botryoidal chalcophanite on the front of the piece is very noteworthy. This Santa Eulalia specimen comes with a label with concise mine locality information, indicating that this is, indeed, a significant, large and rare specimen.
