This specimen comes from a Canadian collection which was focussed on native elements. This was originally purchased from an old stash with was brought to market 20 years ago. The specimen displays herringbone-patterned spinel-twinned silver crystals. It comes from the El Bonanza Mine, Port Radium, North West Territories, Canada.
It is difficult to get just copper chisel chips anymore. This specimen with both copper and silver is unique. As shown in the photos there is a generous amount of silver. This piece was acquired from the collection of John Perona in August of 2014. I in turn purchased it from Michigan collector, Ed Coleman, last week. It is from the Cliff Mine, Keweenaw County, Michigan.
