A fine copper specimen, of a display quality similar to old 1800s-era Michigan pieces, with extremely sharp crystals to 1 cm forming thick clusters on a slight center of rock matrix. The association of contrasting green malachite (or another copper oxidation mineral) is a welcome accent, and immediately tells the eye that this is NOT from Michigan, as the crystal quality and structure might otherwise indicate on first glance! This is an important copper specimen from a rare copper origin in Mexico, so uncommonly seen in the specimen world that we were entirely unfamiliar with it and had to ask Dr. Peter Megaw to track this down for us and confirm it. According to the mining company website, Vizsla Silver Corp: The newly consolidated Panuco silver-gold project is an emerging high-grade discovery located in southern Sinaloa, Mexico, near the city of Mazatlán. It apparently will produce considerable tonnage of silver and gold, with associated copper. Apparently a number of older mines are already present, in this recently unified project. This particular specimen was #197MX in the collection of Kurt Hefendehl of Germany, indicated he purchased it prior to the early 2000s. We include it in this larger update of Mexican specimens from the Ruben Avila collection because it seemed a fitting place to show such an important copper, in context of an important Mexican location collection which did not have one of these present within it. We feel that even if this were from Michigan, where such copper is more typical and abundant, this would fetch a good price. From Mexico, it is much more desirable than the mere aesthetics alone. This is a heavy, attractive piece with good color, and is complete all around.
