From the new find of 2007, this is another great discovery for this locality. This particular piece is a remarkable, very well crystallized, very rare, specimen consisting of small, bladed, beautiful blue color, radiating aggregates of Vauxite coated with tabular blades of greenish-white Paravauxite and Quartz on minor clay (probably decomposed Allophane) matrix. There are also some very tiny spots of brownish-tan Childrenite on the specimen as well. This piece is from the type locality for Vauxite and Paravauxite which were originally discovered along the Contacto and San Jose veins in this mine and first described by Sam Gordon and Mark Bandy.
