Oops, just noticed the topic after searching for my graphite specimen from Tsumeb.
The specimen is very brittle and light in weight. Nothing metalic.
I've seen much bornites over the years and this one is certainly not.
Looks more like shungite with the conchoïdal fracture.
The blue shine is probably due to the background I used or the T-shirt is weared while I took the pic.
