Check their cores for - graphitics and carbon black.
Moreso carbon black - which is saught afterr for its electrical / properties / anodes ( ev space )
Im seeing - marble...
marble is made from limestone that became overheated.
Even the gloss shining black - looks like glass could be tourmaline - rhyolites overheatred turining to
gem like glasss...these are usually found near graphitics and carbon black minerals.
If one zooms in...
you'll see a healthy dose of, carbon black...
this is also the stuff - graphene is made ourt of.
graphene markets are well... hello.
Yip.. the junior should have their cores assayed for carbon black and check for its carbon purity.
pretty simple to do...
