Item Description

Whitneyite is a RARE variety of arsenic-rich copper. The initial description had a high arsenic content (up to 11.5%) and was connected with some intimately associated Algodonite (a Cu-As alloy). This is a very rich, solid hefty nodule of this rare copper ore from the famous mines in Houghton County. From an East Coast collection and comes with a century-old faded label. A historic and RARE old specimen from Copper Country. Mass is 268 grams. A MUST for the locality or species collector!
