I've been having a bit of a browse on the Museum of Wales Minearology database. I was vaguely aware of Glasdir Turf Copper etc, but not really aware of the porphory copper that it was derived from. All this appears to be based on Afon Wen, and its fault and intrusion. So, any hints for a Friday afternoon mooch? Not this Friday though, one for when summer gets it's act together.

Cheers, Robin

Found a geological itinerary, but unfortunately, he hasn't given grid references.

Some side investigations suggest locality 4 might be around SH 748 253

The porphyry Cu is part of a linked geological trail we put together some years ago. It's a good day out. Note that the porphyry Cu exposure is a SSSI. There's a trail guide available here:
