Description

No it's not a Cornish specimen ! This unusual piece was collected from the Cattlegrid mine and has only recently been unwrapped !

It is a superb specimen for an Australian locality featuring crust of crudely crystallised  'balls' of chalcopyrite to 3 mm across on a white sandstone matrix typical of this locale.

Some minor micro quartz crystals are present. It displays well and there is no damage to be found.
