Azurite with Malachite

specimen number:
2063163

location:
Morenci Mine, Greenlee Co., Arizona, USA

description:
A grouping of lustrous deep blue bladed azurite crystals with very little attached matrix. Minor green malachite present. In good condition with slight micro damage present.

The Morenci Mine, located in Greenlee County, Arizona, is one of the oldest and largest copper-producing operations in North America, with mining history dating back to the late 1860s and early 1870s following initial discoveries by pioneers like Army Captain Willcox and the subsequent involvement of the Lezinsky brothers. Geologically, the deposit is a massive porphyry copper system centered on intrusive monzonite porphyry cutting through Precambrian granite and Paleozoic sedimentary rocks, where extensive supergene enrichment created vast blanket deposits of copper ores. Historically, operations transitioned from early underground high-grade extraction to massive open-pit mining and modern heap leaching, turning Morenci into a cornerstone of the American copper industry and a notable producer of fine secondary copper mineral specimens.
