(Mina La Blanco)
La Blanco is a small
Co-Cudeposit close to the town of Freirina; mined on a small scale in the 19th century (Ref.: Maurizio Dini).
Type locality for the now discredited species "Freirinite", which turned out to be lavendulan.
Some interesting looking samples here.

A beautiful, large matrix specimen with a huge display face covered by sharp, metallic, acicular erythrite crystals. The matrix is
heavy cobaltite-rich matrix, solid ore, weighing several kilos. This specimen was given by the eminent researcher in the area, Dr. Domeyko, who sent many study samples to the Academy during its heyday. Ex. Academy of Natural Sciences Philadelphia Collection.
