Arsenohauchecornite Locality: Vermilion Mine, Denison Township, Sudbury District, Ontario, Canada Dimensions: 1.7cm x 1.0cm x 0.7cm Desciption: Arsenohauchecornite is a very rare Ni-Bi-As sulfosalt (3 localities worldwide - MINDAT) and this famous Canadian mine is the Type Locality. Irregular masses and microcrystals of bronze-metallic arsenohauchecornite are noted on three sides of the thumbnail matrix. A couple of chalcopyrites are also noted. This is a rich example of this rarity. Mineral

Arsenolite (Size: 6.0 x 4.3 x 2.9 cm) Locality: White Caps Mine, Manhattan, Manhattan District, Nye County, Nevada, USA (Locality at mindat.org) Arsenolite is an uncommon arsenic oxide, formed as an oxidation product of arsenic-bearing sulphides in hydrothermal veins. Highly lustrous and translucent, yellow-green and colorless octahedrons are festooned on the sulfide matrix on this very rich and showy piece from the famous White Caps Mine at Manhattan, Nevada. The White Caps produced the finest USA stibnites. Old-time, very high quality and rich material. Ex. Howard Belsky Collection. Mineral

The grains used for single-crystal X-ray diffraction study were extracted from the red (arsenoústalečite) and blue (stibioústalečite) boxes. Holotype sample. Mineral

Arsentsumebite, Mimetite Locality: Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia (Locality at mindat.org) Size: 5.6 x 4.3 x 2.9 cm. An exceptionally rare and rich, very old-time specimen. This was originally labeled as pyromorphite (but never checked by analysis). Pyromorphite is not reported in crystalline form of any quality from Tsumeb and this would have been a miraculous piece. Further study has confirmed it is actually arsentsumebite pseudomorph after mimetite. Specimens of this type were reported to have been found in the upper oxidation zone, and so it most likely dates to 75 years or more in age. Ex. Gary Hansen Collection. Mineral
