Chukilite
Chukilite is a rare lead copper telluride mineral with the chemical formula PbCu3(TeO3)2(OH)2. It is a secondary mineral found in oxidized tellurium-bearing copper deposits.
Chukilite typically occurs as aggregates of platy or acicular crystals. Its color ranges from green to bluish-green. It possesses a vitreous luster and a Mohs hardness of 3.
The mineral was first described in 1989 from its type locality, the Bambollita mine in Moctezuma, Sonora, Mexico. The name is derived from the Quechua word "chuklla," meaning "copper," in reference to its copper content.
Notable occurrences of chukilite, in addition to the type locality, are relatively scarce. It is found in association with other rare tellurates such as dugganite, emmonsite, and zemannite.
Chukilite is of interest primarily to mineral collectors and mineralogists due to its rarity and unique composition. It does not have any known significant industrial applications.
