A fine cluster of inter-grown spherical growths of chalcopyrite with associated sulfides naturally, although weakly, held together in a cluster. This rare material came out of a few pockets in 2017-18 and not much has turned up since, although ball and oddly shaped chalcopyrite has continued to come out in small, erratic finds during COVID. We even have some of these on matrix, for those who doubt they are natural (see iRocks.com Wisdom Pocket Blog for photos, as well). Yet, they are very similar to "blister copper" growths found at other localities, particularly Cornwall and Connecticut, in the past centuries. Although rare, such spherical growths are not improbable and with all the wealth of China's copper mines, we see an amazing variety of forms turn up.
