21NBX11: An important find from the well-known Atrevida mine in the summer of 2015 uncovered a single pocket, with coatings of greenish yellow millimeter-size Mimetite crystals, very sharp, translucent, and formed by an elongated prism and acute dipyramid. The Mimetite more or less completely covers the cubic Galena crystals that are implanted in a matrix covered with aggregates of white lenticular Baryte crystals. Most specimens also had small aggregates of Pyromorphite and lamellar Wulfenite crystals that can be located upon detailed inspection. Mimetite was a previously known species in this mine but not with this very sharp presentation, completely covering the Galena but absent from the Baryte.
