Thank you, I don't know why I couldn't work that out!  I don't know where this was found as it was in a box if stuff left in a house I bought but I live in Cornwall UK if that helps.

related to an answer for: Thanks, however....

It looks to be sedimentary. It looks like shale or coal. If you could answer a few questions, is it magnetic? Is it heavy compared to other rocks of comparable size. Maybe tin.

So, I typed in raw tin and found a specimen like yours. It is weakly attracted to a magnet, paramagnetic as opposed to ferromagnetic. Tin production in Cornwall is ancient..
