Alfred Larose
Formula:
(Cu,Ag)21PbBiS13
Colour:
Pale buff (polished section)
Lustre:
Metallic
Hardness:
3 - 3½
Specific Gravity:
6.19 (Calculated)
Crystal System:
Orthorhombic
Name:
Named after Alfred LaRose (1870-1940), blacksmith and prospector who was one of the principal discoverers in 1903 of the rich silver deposits of the Cobalt area of northern Ontario, which led to a huge exploration and mining boom in the region. Two versions of the name are found in the literature, LaRose and Larose, the latter traditionally used by the family, but the former used in the naming of the mine. LaRose was inducted into the Canadian Mining Hall of Fame in 2003.
Note: Electron microbe analyses of larosite from Norway (Cook et al., 2010) gave Cu20.47Ag3.68Fe0.22Pb1.01Bi1.06S15.00 calculated on the basis of 15 S atoms.
