Choix in Sinaloa, Mexico, is a historic mining area that was worked for silver, lead, and zinc beginning in the 19th century. The deposits occur in hydrothermal veins cutting volcanic and sedimentary rocks, and mining continued intermittently into the 20th century. In the oxidized zones of these deposits, smithsonite formed as a secondary zinc mineral, often occurring as botryoidal crusts and smooth masses. Smithsonite from the Choix area is known for its attractive colors, including blue, green, and pink tones, and is valued by collectors for its appearance and classic locality.
