The enargite here is being replaced by luzonite, is probably mostly replaced - but I do not think the replacement is 100% yet because of the general look of it. I could be wrong, and I cannot pin why I feel this way, but it just seems off in color or lustre, to me, compared to the full luzonite pseudomorphs I have seen in the past. Perhaps it is caught in transition, partly each species. Rarely do you see these specimens on matrix and here we have it on both pyrite and host rock matrix.

The word comes from the Greek *enarges* — meaning distinct — chosen for the sharp, distinct cleavage along which its crystals split[1].\n\nThe mineral was first described in 1850, by the German mineralogists Johann Friedrich August Breithaupt and Carl Friedrich Plattner[2]. They examined material from the copper mines of the San Francisco vein, in the Junín Department of Peru — still recognised as the type locality, the place where the species was first defined[3].\n\nFrom there enargite turned up in copper districts across the Americas and beyond. Notable specimens came from Butte, Montana; the San Juan Mountains of Colorado; and the Tintic and Bingham Canyon districts of Utah[4]. Mexico, Argentina, Chile, the Peruvian camps of Morococha and Cerro de Pasco, and the island of Luzon in the Philippines all yielded the mineral as well[4]. In several of these places it gathered in quantities large enough to be worked as a copper ore — the role that earned it a place in mining history[5].","claude-opus-4-8","1.7.0",{"markdown":784,"model_version":781,"prompt_version":782,"reviewed_at":11},"Where it gathers in quantity, enargite is mined as an ore of copper — nearly half its weight is the metal[1]. It concentrates in one kind of deposit above all: high-sulfidation epithermal systems[2]. These are ore bodies formed near the surface by hot, strongly acidic fluids rising from a magma below. They often sit close to a porphyry copper deposit — the large, low-grade bodies that supply most of the world's copper[2]. Butte in Montana, Chuquicamata in Chile, and the copper camps of Peru and the Philippines have all produced it[3].\n\nThe catch is the arsenic. Enargite carries a heavy load of it — the chemical formula is Cu₃AsS₄ — and arsenic is treated by smelters as a troublesome impurity, not a product[4]. Melted with the copper, it is diluted and emitted in the gas and slag streams, which forces special collection and handling so it does not escape as toxic dust or fume[4]. Buyers cap how much arsenic a concentrate may carry and charge a penalty above that limit, which makes enargite-rich ore costly to sell[5].\\\nThe usual fix is roasting — heating the concentrate so the arsenic volatilises and leaves through the gas before smelting[6]. Even so, the captured arsenic becomes a toxic waste that must be locked into a stable, disposable form[6].\n\nBeyond the copper it carries, enargite is also collected as mineral specimens — its sharp, lustrous black crystals are prized[1]. Because the mineral is an arsenic compound, specimens are handled with care: dust should not be inhaled, and hands are washed after contact[4]."]
