Seriously hard-to-identify minerals. I am sure both minerals or in the matrix, since it was originally identified by Dr. Jaroslov Hrysl. In fact the Hocartite is visible on the specimen as spongy-looking dull black semi-spherical crystal groups to about 1mm and shown in the photos at the yellow arrows. At times, rocking the specimen back and forth a brassy color is seen. A good phot of Hocartite can be seen in Bernard and Hyrsl "Minerals and Their Localities on page 320. As far as the Pirquitasite goes, I just don't see it.
