From the new find of 2009, 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 hosting a pale greenish Paravauxite on minor clay (probably decomposed Allophane) matrix. It is very difficult to obtain any specimens of this incredibly beautiful phosphate and to find two "Vauxite" species together on one piece is fantastic. 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.
