This wulfenite specimen was news at Ste Marie Show in 2005, it was part of small find brought to the show by Guangha (George) Liu.
The locality was given as Mian Ning Mine in Sichuan, China. At the time there was a lot of discussion, but the find was short lived.
The specimen featured was quite large and rich, not the best and landed in my collection, packed away for a number of years it emerged recently chez TVM.
Taking photographs of the piece I noticed a small yellow blob to one edge. On closer investigation this stands out as a single roughly prismatic mimetite crystal with wulfenite developed in alignment in tangents across - possibly epitaxially - see below.
I don't recall seeing this before, and this is the only mimetite crystal I can find on this specimen or have seen on this material.
A true needle in a haystack but worthy of note I am sure,
