In 1977 he reopened the now-famous Sweet Home mine in Alma, Colorado to mine specimen rhodochrosite, hubnerite, fluorite, svanbergite
and goyazite crystals.
Brussilhof, near the town of Radium in British Columbia, about 200 thumbnail and small-miniature specimens of very fine dolomite, some with microcrystals of svanbergite
, were found last spring.
For example, he made in-depth studies of the mineralogy of the now-famous Brumado mine in Bahia, recovering countless superb crystal specimens of uvite, dolomite, hematite, magnesite and Japan-law twinned quartz, as well as rarities such as chernovite, agardite-(Y), florencite-(Ce), woodhouseite and svanbergite
among many others.
Other minerals encountered at Brumado include: talc, goyazite, svanbergite
, chernotive-(Y), wakefieldite-(Y), florencite-(Ce), anhydrite, celestite, barite and numerous other species.
Kosnar purchased back many Sweet Home specimens from high-graders, including 1-cm tetrahedrite crystals, ruby-red hubnerite crystals, twinned stromeyerite, and good crystals of goyazite, svanbergite
and fluorite (Bancroft, 1984).
Paul Hlava (written communication, 1994) confirmed the identification of the Ransom sample and indicated that in addition to an inner composition of goyzite, there was an outside growth of svanbergite
