According to University of Cambridge they have discovered a new mineral from Penberthy Croft mine and have named it
Penberthycroftite......I bet they were up all night thinking of that one :lol:
Hopefully this will only be a temporary name.
I was discovered microscopically, so gurt big chunks are unlikely to exist.
It's basically an arseno suphide-ish mineral, and has associations with most of the common gangue materials found in practically all Cornish metal mines, and so could be present in other mines.
