Description

A real oddity from the Corbold Section of the Mount Elliot Mine, in the very early days of mining at Mount Elliot a number of superb native copper in gypsum specimen were recovered and of more recent times some attractive chalcotrichite specimens have been on the market. This is the first and only cuprite var chalcotrichite specimen that I have had the pleasure of handling, it came from the Jack & Dawn Leach Collection, whilst they collected extensively in the area, I do not know how they came by this specimen.
