In 1977 he reopened the now-famous Sweet Home mine in Alma, Colorado to mine specimen rhodochrosite, hubnerite, fluorite, svanbergite and goyazite
To top it off, the Tysons offered a handful of fine thumbnail wardite specimens, with sharp, lustrous, pale blue-green pseudo-octahedral wardite crystals to 1.5 cm associated with white microcrystals of goyazite
; and they offered a few exceptional clusters of glassy pale green augelite crystals, and sprays of dark blue-green acicular gormanite as well.

Associated minerals are: goyazite
, "apatite," siderite, quartz, calcite, marcasite, pyrrhotite and pyrite.
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).

Among the more unusual minerals they found was a bonanza of goyazite
crystals (2-4 mm) with steep rhombohedral form, a habit nearly unique to Greenwood.
These crystals were originally thought to be the related species goyazite
, but chemical analysis has refined the identification to florencite-(Ce).
was observed on a single specimen as microscopic, pale, yellowish tan crystals as much as 1 mm in size, interstitial to small, prismatic quartz crystals.
