Baryte with Chalcopyrite

A somewhat unusual combination of creamy-grey blades of opaque to semi-translucent Baryte densely coating a sturdy matrix of brecciated Chalcopyrite.  From Mount Wellington mine, near to Truro in Cornwall, the Chalcopyrite is largely tarnished to a dull sooty black, but where exposed is bright brassy-gold with a rose to cherry-red iridescence.  An interesting combination of Baryte with Chalcopyrite from the long since closed Mount Wellington mine.
