After the first significant gold discovery in Serra do Caldeirão in 2015 (An opportune harvest of Gold in Serra do Caldeirão claims, Brazil), there have been new small finds in the area.

A novelty at Tucson 2016. Parallel aggregates of very sharp and well defined octahedral crystals, with sharp skeletal growths.
