Elevated Bi content in till (10s of ppm) is likely hosted in the Bi-rich minerals native bismuth (Bi), bismuthinite ([Bi.sub.2]S3), bismutite ([Bi.sub.2](C[O.sub.2])[O.sub.2]), and joseite (Bi4(S,Te)3) that were recovered from the heavy mineral fraction of metal-rich till samples overlying and up to 4 km down ice (southeast) of the deposit (McClenaghan et al.
An even more arcane Bolivian rarity is joseite ([Bi.sub.4]Te[S.sub.2]), which showed up in Tucson in the form of the first euhedral crystals of this species ever discovered: the loose, dull, metallic gray, bladed crystals, reaching 1.75 cm, were found enclosed in massive native bismuth at the Tazna mine, but popped out freely when the bismuth was cleaved; Alfredo Petrov offered a few small-thumbnail crystals at the Smuggler's Inn.
The nodules contain numerous inclusions of other species including hedleyite, joseite, hessite, electrum and graphite.
