[Rockhounds] need help to identify these rocks

[Andri]

Greetings to all the experts in the board!

I wish I could gather all detailed/technical info before posting this, but
I'm not a geologist, so I dont know much about this specimen. I hope that is
okay with the moderators. :) These rocks are taken as sample to what we
believe is Fe (iron ore?), but the looks is abit unusual: black, shaped in
chunks, weighing around 150gr,480gr, and 3kg for the biggest chunks. If you
see the photos I attach here, you can see that the stones has some cavity
(holes?) in it, and in some parts it glitters. These rocks were found in
mountaineous location, and can be found both on the surface and beneath the
ground.

 

Please see photos here:

Thank you very much in advance,
