Found at moonta sa,

really heavy doesn't scratch to easy either and has a bit on it that looks like it had been melted at some point

Pretty sure this is the same stuff we came across when in Moonta last month at the Copper mines, It's 90% iron. Didn't scratch also...

I can't remember the name of it but I'll ask my uncle, he knows.

Looks like slag to me.
