Cobalt district ores occur in distinct mineral assemblages as outlined by William Petruk in the 1971 publication "The Silver-Arsenides of the Cobalt-Gowganda Region, Ontario". This specimen fits well in group 2 of Petruk's which contain high Silver and Allargentum. It is sawed and polished on one side. The Silver is easily seen in matrix as well as the brassy luster of the Nickeline and Breithauptite.
