I can't exactly say that I can point to the areas where the Uytenbogaardtite occurs on this specimen. However, I can say it is in the area where the Gold particles are seen in the photos. The Uytenbogaardtite is probably the dark grey with tinges of purple. I've sold these slabs before and all were of excactly the same. The slab was undoubtedly cut for polished ore microscopy and EDS. Some of the areas, especially on the sides where it is not cut smooth, you will see a natural break lined with dark gray, sectile, Acanthite.
