Item Description

A seldom seen specimen of native copper from the Isle Royal Mines, very close to the modern day location of Michigan Tech. This piece is a fairly aesthetic flattened plate of copper with a lovely reddish-brown patina and minor associated mint-green colored Malachite. A great piece for any fan of native elements, copper or minerals of the Upper Peninsula of Michigan. Specimen weight is 92.9 grams. From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974 ( https://www.mindat.org/photo-326405.html ).
