Glassy blue crystals of Minasragrite with pale green prismatic Retgersite. Both were confirmed with XRD. The black matrix is Patronite. All three are rare minerals. The American Vanadium Company mined the deposit in 1906 and is located high in the Peruvian Andes. It was first large scale commercial vanadium deposit to be mined and had a profound effect on the steel industry. An old copy of the label by "Jandorf" is included (see prov. tab).

This is a good representative specimen of Sincosite from the Union Carbide mine. The deposit was mined for vanadium. The Sincosite was a one-time accurence found by the mine geologist Paul Thompson. The Sincosite on this specimen reaches only 0.5mm and occurs as square plates and little rosettes. Sincosite is a fairly rare mineral found in only a handful of deposits around the world.
